Reconditioning / Repair an Old 12V Car Battery: Part 2 With CCA Results
HTML-код
- Опубликовано: 5 окт 2024
- In this video I show you how to revive or recondition an old dead car battery with Epsom Salt. We also cut open a battery so I can show you how the process works. This is a cheap way to save a battery from the dump.This time I take 3 junk car batteries and manage to repair two of them back up to 80-90% of the cold cranking amps.

Very interesting video. Back in the early 70s my wifes Dodge wouldn't start. We were poor as church mice. I remembered my dad pouring the acid out of a bad battery and flushing it out with a strong flow of water. I set up two cinder blocks spaced almost the same width of the battery. Turned the battery upside down on the blocks. Attached a sprayer wand on garden hose and sprayed up into each cell until it ran clean. Let it drain then poured old acid back in thru filter materal. Installed the battery and the car cranked without first charging it. This has worked about 1/2 the time over the years. Interesting I could have revived the other1/2. Thanks for the video. Didn't have RUclips back then. We had popular science magazine, Car and Driver, Ask Smokie. I would go to the library and check out repair manuals or copy the pages I needed on a memiorgraff machine at .05 a page. Still got them on file in my shop. Thanks for the video.
Making use of the ruclips.net/user/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type
Scammer bs story to sell a book.We are here to learn something not BUY this guys book.
The best detailed epson reconditioning with detailed proof on RUclips so far
This is by far the best video in the subject... So I did it to a battery (500 CCA) someone sold me for $8 dollars. I charged it up, leave it rest for 5 hours and test it with a Foxpro Battery Tester and give me the next results:
Volts: 12.89 V
CCA measured: 296 CCA
CCA rated: 500 CCA
SOH (State of Health or life expectancy): 50%
SOC (State of Charge): 100%
Resistance: 10.28 microOhms
Note from Tester: REPLACE BATTERY
The battery was made in 2016. It is almost 4 years old and was used in a Honda Civic. So I drain all the acid, rinse the battery with tap water almost 15 times, prepare a solution of Epsom salt to a concentration of 20g/100ml of deionized water and put it to charge in a professional charger I bougth. The charger took almost 5 hours to be 100%. I let it rest for 5 hours and then test it with the following results:
Volts: 12.29 V
CCA measured: 335 CCA
CCA rated: 500 CCA
SOH (State of Health or life expectancy): 56%
SOC (State of Charge): 54%
(yeah... the tester tought the battery was undercharged but actually I believe the voltage with the epsom salt is much lower than with sulfuric acid)
Resistance: 9.11 microOhms
Note from Tester: GOOD BATTERY-RECHARGE IT
You can tell there was a improvement in the measures... So I naturally discharge the battery with a inverter (I know... this isn´t the best to discharge a battery because only made it to 11V, it is better with a bulb like in the video but I can´t find one DC bulb in my city). After "discharging" the battery with the inverter I put it charging once more. The charger only took 50 minutes to full charge it again (I assume this is because the discharge was not complete). After this I let it rest for 5 hours and I did a new test with the following results:
Volts: 12.12 V
CCA measured: 351 CCA
CCA rated: 500 CCA
SOH (State of Health or life expectancy): 59%
SOC (State of Charge): 40%
Resistance: 8.73 microOhms
Note from Tester: GOOD BATTERY-RECHARGE IT
The CCA improve (... not much by the way, from 296 CCA originally full charge with sulfuric acid to 351 CCA "full charge" with Epsom Salt electrolyte), so I am tempted to continue discharging and charging again like in the video. But something ocurred. I accidently drain some Epsom Salt diluited in water directly from the battery (the battery was boiling being charged and the levels of water raised so I had to drain a little) and put it in a plastic container with a alum teaspoon inside. After 2 days I figure out the color of the Epsom Salt solution changed to blue and the surface of the teaspoon had a black precipitate, so I thougth maybe the magnesium solution with electric charge on it was corroding the alum or maybe in the Epsom Salt solution after be charge in the battery formed some sulfuric acid. This made me do some research about magnesium corroding the lead plates in the battery and efectively found in some websites information about it. So obviously this is counterproductive to the reacconditioning process so I am tempted now to drain all the epsom Salt solution from the battery and fill it with sulfuric acid again.
But to continue the test I decided ignore this fact and continue the cycle process. So I discharge and recharge the battery again. I did the test but this time let the battery rest for 24 hours after charge. These were the results:
Volts: 11.84 V
CCA measured: 317 CCA
CCA rated: 500 CCA
SOH (State of Health or life expectancy): 53%
SOC (State of Charge): 5%
Resistance: 9.62 microOhms
Note from Tester: GOOD BATTERY-RECHARGE IT
So this is a little dissapointing because the voltage drop in 24 hours and the CCA too. The next step is to drain all the epsom salt solution from the battery and fill it with sulfuric acid recharge it and test. I will do this in the next days...
PARTIAL CONCLUSIONS
So far we can make some conclusions....
1. There is not "magic" in the Epsom Salt. It worked like a desulfator maybe with the increase in the electroconductivity (evidenced in my case with the marked improvement in the resistance) made by the magnesium cations in the negative plates.
2. The Epsom Salt solution inside the battery can corrode the lead plates, so it doesn´t works like a electrolyte replacement.
3. The Magnesium sulfate has a lower residual voltage than sulfuric acid, so thats is not good for cars.
4. After the Epsom Salt ("treatment") maybe it is necessary to drain it completely from the battery and refill it with sulphuric acid again to restore the voltage and avoid the corrosion...
Note: maybe some of these "conclusions" are wrong. So please let me know it... Please.
I will update the results after drain all the Epsom Salt and refill it with sulphuric acid.
Thank you.
Watch video 2 on my channel. Great post.
The voltage drop and lower CCA indicates a single cell (2V) is failing. Drain and save the acid. Drain the battery a few times with plain water into a bucket as there might be a buildup of lead precipitate that has come loose, that is causing a cell to start shorting. ie. make sure the inside of the battery is as clean as you can get it. Drain the water, rinse with de-mineralized water and re-add your acid. 12.6V or above is what your battery should be when new and ready for service.
If it's still no good, then the plates are shorting somewhere, and the battery will likely never be suitable for cranking a car properly, particularly under load. The lead grills they use do lose pieces over time and those pieces are what can cause a short. A mechanical issue with a battery like that is not worth persisting with.

You are teaching me a lot about restoring old battery’s as I have restored only one however it is 2 plus years old and still doing the job.
Any update after replenishing with battery acid?
Ok so i watched this over and over maybe 20+ times, and then scoured the internet for hours trying to figure out WHY this does what it does. First i want to start off by nailing down exactly what the two plates are. You have a lead plate Pb and a Lead Oxide plate PbO2. In the normal sequence of a battery you have sulfuric acid in betweent he two plates. until the Sulfuric acid is in place you ahve zero charge. When you put the acid into the battery it dissolves the lead on the negative plates and you release hydrogen gas and two free elections which flow towards the + plate. The sulhate ion free electrons and lead oxide combine to make a lead sulphate on the surface of the battery. Typicall this is a soft lead sulfate.
On charginging this whole process goes in reveres to essentially put the electrical energy BACK into the sulfuric acid. When the battery sits for extended periods of time the lead sulpahte becomes crystallized and is exceptionally tough to remove by charging alone. It is this reason that old timers suggest a very low current (like .5 amp) charging to slowly crack some of these crystals open. This is also whay old or discharged batteries will get destroyed in the winter. The reaction removes the sulfuric acid and makes it essentially water. Wehn water freezes, it expands and will cause the side of the battery to bulge and can also break off sections of battery cells creating dead cells because parts fall off. Sulfuric acid at the proper Specific gravity ensures the proper percentage or Molarity. At the 33-40% or 3 Molar of sulfuric acid, sulfuric acid has a freezing temperature of -50 to -70C (-58F to -94). Maintaining the correct concentration and full charge of a battery in cold temps are even more critical than just the reduced reaction at a colder temp (hence CCA 0deg)
So what i finally found was an old electrical review journal that explained how using Carbonate of soda, also koown as baking soda would dissolve this lead sulfate layer. Essentially the epsom salts has almost the same reaction. If you know anything about chemistry and looked up Magnesium or sodium blocks of metal thrown into water you have seen how reactive they can be. By putting the magnesium sulfate and then putting a small charge on it you are essentially softening up the lead sulfate and rendering it able to dissolve into solution again. The emptying and refilling every so often allows a refreshing of a once saturated solution with a fresh unsaturated solution. I have followed this video and i am working on a 1080 CCa battery 900 CCA @ 0deg that was all of a whopping 50 CCA when i started. I am currently at 500 CCA and i am warming it up as it was outside. I susupect i will pick up about another 200CCA. I Picked up 6 quarts of battery acid (1.28sg or 36% sulphuric acid) I am hoping it will jump a further 200 on top of that. If it does in the warm enviornment then i am abouve 90% capacity. I will post again if you like what the final results are here.
Yes, I did the same research before I started the tests, the difference is that I cant get 1 million views by doing a 15 minute explanation on the science of why it works, no one but us cares :)
Car Groves you could do a 5 min montage for a quick and dirty ... lol
Wanted to know how your experiment turned out.
@@julianparker8681 So the first one was a 1090 amp battery (900 CCA) it was only 20 months old . When i first pulled it, it was a mindblwing 63 CCA. It is for a 6 cylinder diesel car. I ran it through about 2 different runs of epsom salts and ran it through 5 -6 cycles of each. After the second time around i rinced and drainded from tap water until all the little "SAND" stop coming out. At this point i realized i didnt have the correct specific gravity of sulphuric acid. It needs to be 30% and have a specific Gravity of 1.268 ... you can buy the tester on amazon. so i went to a NAPA and got a 6 quarat box of the correct barrery acid for $20. Only thing is when i poured it in, it reacted and dropped it down to 1.177. so i drained it to attain the volume that i needed in the battery and put almost twice the volume and put it in the oven to concentrate. DO NOT MICROWAVE IT. you will get nucleation sites and you will get acid splatters. The sulfuric acid boils at 460F so set the oven at 400F and the water will cook off. It will never boil because of the sulphuric acid. i did this until when it rested in the battery it can the correct Specific gravity. When it was at this point i tested and came up with 945 CCA and it turned over the car. I have since gone through this procedure with 3 other batteries with the same result.
@@kamaksi24 so you did the epsom salt/demineralized water soak/charge cycle first...5-6 times. then drained that out and added the proper sulfuric acid mixture into the cells testing the acidity of solution until you get it to 1.268, adjusting the solution by concentrating it.....correct? I have 6 10 yr old 6V batteries on a golf cart that holds a charge for about 2 runs around the park in FL...will do this when I get back down for sure!
Computer chargers are a bane to mechanics everywhere. To solve the "Bad Battery" indication on my computer charger, I made a set of clip(jumper) wires to allow connection with another known good battery. The secret to doing this is to put a blocking diode and 20 amp fuse into the positive lead. This allows the charger to "see" the good batteries voltage and turn on....but the blocking diode keeps all the charging current from going to the good battery...instead the charge is put into the "bad" battery. You can usually disconnect the good battery after about 30 minutes of charging. The 20 amp fuse is to protect the good battery should the bad battery have an internal short. The diode I used was a 35 amp diode out of a junk alternator. Been using this trick for over 4 years and it hasn't failed me yet. Total cost was about $5 for the 2 pairs of battery clamps....... as I had everything else in my junk box.
Its a poor design, great work around.
Ive done that quite often as well!
Great video. I love that you take us through the experiment that you're doing. I can say from some little experience with building hydrogen generators that what you've got going is something similar. A hydrogen generator basically is made up of plates close together with a water salt (Usually Sodium Hydroxide) solution. Just like a battery. Then a voltage is run through the plates and the small arc's in between the plates actually split the water molecule H2O into gas which is H and O2 (The O always binds with another O making it 2) So the bubbles that you see are H and O. So if you use a water solution in a closed battery you will always pop the caps when the alternator is constantly running amps through the plates. Hence why for batteries an acid solution is used which reacts to lead where a salt solution would be better with a non corrosive plate like low iron steel, platinum, or gold. The combination of salts, oxygen, and water will corrode most anything very fast. Even good steel you can actually watch the rust grow from it when amps are put to it. What im interested in is if you use the epsom salt like youre doing then rinse and replace with fresh sulfuric acid then will the batteries be brand new?
I was wondering the same thing. After cleaning charge with battery acid
You could talk better with the mask on? Put mask back on clown. Maybe I'll understand u then😅😢❤
The people I find I can trust the most with battery issues are those that wear flip flops while pouring out sulfuric acid and have no regard for the Hydrogen gas that can be present in a lead acid battery case as they use a vented brushed motor based Dremel to cut open said battery.
In college, my car battery was pretty much dead. I put an aspirin in each of the cells and a few hours later, there was enough power to turn over and start my 4 cylinder car. I was amazed.
Yes batteries are getting expensive for sure, and I have time on my hands to do this.
Thanks for you video. I missed some parts in the video, that maybe were just implied,
but here you go anyway, maybe you will find your way back around to these questions:
1.Did you re-use the old battery acid? or purchase new?
2.did you use 2amp charge on old battery with top removed? can you use 10 amp or 50 amp for a faster cleanse?
3.when you dumped the esalt distilled solution when you were getting junk out, did you use new esalt distilled water solution? or use the same solution you just dumped?
4.I read somewhere you could use baking soda instead of e salt? You ever tried that?
Fantastic video, definitely one of the better Epsom salt battery fix videos.
I have seen some people using 200A chargers, in 15 minute intervals as the high current significantly increases the cleaning efficiency of the Epsom salts. 👌
Im doing my girlfriends Audi battery that just died randomly, have had it on charge, with a dumb charger for 2 odd days and day 1 was 12.7 50cca day 2 of charge 8.5v 10 cca. My intellicharger wont over charge it, is what you need. So i will be using my 200amp dc welder. Will not be using Epsom salts method, but the high current for 15 minutes 5 times. Will report back with my feedback.
@@travismailsa1 well? Did you have any luck
@@THIRSTYGUMS yup all revived. Top up levels, ran at 50 amps for 15minutes then the next 4 cycles I went at 100 amps, obviously not just going straight to 100 amps. . Battery still going strong a week later. I have about 5 deep cycle batteries for our inverter that didn't hold much charge after a year. Will be repeating the same process as mentioned above
..... Nice fat blue spark at 20:50 ! Might be a good idea to wiggle the clamps a bit before switching on the charger to ensure a good contact. :-)
You are a true hero. Took Walmart batteries still under warranty and revived them in the interest of educating total strangers like me. Props to you brother. Thanks for your hard work. Loving your garage.
Glad I could help
How's it doing a year later?
The best video that I’ve seen on this subject. I bought a used golf cart for cheap. It has 6 6 volt batteries. Under load 4 are weak and 2 are bad. I have just a simple load tester. They all show around 6.4 volts. I think I’m going to try to recover the weak ones first and then possibly move on to the bad ones. With 6 batteries it’s going to take me a while.
Thank you for sharing your knowledge. Great video!
What were your final results?
First thing I noticed was one of those "green top" batteries. I've never had much luck reconditioning ANY of those Interstates. You might get them to take a charge but once they fade they don't recover anything like their original capacity and they seldom hold on to a solid charge... at least the ones I've dealt with. Not sure why, but a lot of those green-top Interstate batteries didn't seem to last past their original warranty but since they're usually pro-rated (you should check on just what sort of warranty the battery actually has) the owner just didn't bother and went with new. It's worth mentioning that some batteries are rather severely budget-based and the construction quality simply isn't what it could be and when they gag out they stay gagged. Nothing you can do will bring them back. I cut one of these budget batteries apart and saw that nearly half the lead on the plates had crumbled off and settled into the bottom of the case where it was shorting out what was left of the plates that still had some lead on them. You ain't gonna get that one back. Thus, when some people say they can recover Any battery, I become skeptical.
The bubbles you're seeing are water being split into hydrogen and oxygen gasses. The Epsom salt works it's way in between the crystal lattice of the lead sulfate and causes it to sluff off the lead cells, providing more surface area for the chemical reaction to generate electricity. More surface area=faster discharge rate available. Great video!
Thanks for watching James
Do you ever drain the salt water out and put acid back into the battery or are we replacing the old acid with the salt water
@@anthonypitts7878 either/or; what happens with the Epsom salt is the sulfate ion from MgSO4(7-H2O)gets donated by the magnesium and binds to the lead(or lead oxide, I believe) in a non-reversible reaction, leaving lead sulfate and magnesium oxide behind.
Lead sulfate is converted into lead metal and sulfuric acid when the battery charges, and reverses during discharge.
This guy reminds me of Don Deluise during the Cannonball run days... 🤣🤦♀️😂🤷🏼♀️😁
Well thank you
@@CarGroves ya, I thought that was a nice compliment too :)
Are you even old enough to Know Dom Deluise!? LoL... Or "HIM"? LOL... CAPTAIN.....??? LOL
I wondered about letting the used acid set, and seeing if the solids settled out of the mix. Kind of cleaning the acid. Good video.
They settle out
Thank you so much for your presentation sir, now i really have an idea on how to reused my old batteries...thank you so much....from Philippines....
What's improving the CCA is the 30A shock you're giving it, that helps clean the plates. You actually skip the epsom salt completely. Just use a DC arc welder with adjustable output, and cycle it 5mins on, 10mins rest. Do that 5 times, some people say 60a for first cycle, 90a for 2-4th, and 115+ for the last, higher depending on how it's reacting to the first 4 cycles. High current zaps the plates clean, not just charging/discharging at low currents. Quite a few youtube vids showing the welder method and it seems to work well!
Best feet PPE I’ve ever seen when dealing with battery acid!
LoL
I aim to please :)
@@CarGroves Great video! Thanks a lot. Did you ever add the acid back to the battery? That part was a little unclear.
@@s.pellegrino7316 yes i put it back in later
Very nice video ,, i appreciate your intrest on battrry reviving ,, hope u will post more videos like this , thank you brother
No problem. I really like being able to see what the battery was doing. Thanks for watching.
Hello bro I'm going to try this experiment so can u say what model charger you have used in this project
Thanks in advance
@@raatheesh Its from Harbor Freight
Schumacher model number bro
@@raatheesh google it
ok so your last comment was to use the epsom salt solution as electrolyte while you recondition then when you have gotten the battery to maximum recovery stage replace the epsom salt solution with the origional battery acid ? do you use a specific gravity hydrometer to measure the h2s04 battery acid =sulfuric acid
That looks like a 1967 Mercury Cougar there in the background! I restored a '68 many years ago. Saw your first video which led me to this video. I own a used car dealership and probably go through ten batteries a month, which average at least $100 a pop! I'm gonna have my mechanic test that pallet of old batteries I have and see if we can bring those back to life.
Yes the solids will settle to the bottom. He is missing a step which is missing baking soda and water to help clean out the sulfate
20:43 always wiggle both to dig into the raw metal.... Do it several times to ensure a zero resistance connection. Also, I'll assume different gasses, if any are released and also this Epsom salt battery might have some bleeder current because the solution may conduct better. So maybe they run down quicker than factory. I can't find any proof of people using these reconditioned batteries over the long haul. Thanks for the awesome info.
been looking for information like this for years and have now found it. Thank yo very much and I have subscribed to learn more tricks. My big problem is that I cannot find a dumb charger which I have looked for for years on all the secondhand sights.Can't wait to get back to it .
We were doing this way back because of MONEY!! It worked great and you were RECYCLING and didn't even know it.😳😳😅😅
As I understand, the plates get corroded.
So why not use vinegar and baking soda? or Lemon juice and baking soda to clean the plates,.... and then heat them up by charging and discharging.
But great experiment of cutting off the top.
Great idea
In video one you use a mixture of the used acid and distilled water/Epsom salt mix. In the second video it was only Epsom salt and distilled water mixture. Which worked better? Also, I've seen many videos of people cleaning and flushing the battery with a distilled water and baking soda mixture. Is that helpful in cleaning the plates?
I had it in old battery that was 550 CCA and it wouldn't start my little four cylinder. And it was cold in the winter time so I brought the battery in the house tried to charge it the charger wouldn't charge it. I took a flathead screwdriver and stuck it down in the cells and scraped lightly around each cell. Then I put it back on the charger it would not charge. I had the Caps back on and everything and I got two pieces of metal and arced it a couple times then it took the charge. It charged up for 2 days on a trickle stuck it in the car and end up using it for another 2 years and sold the car with a battery in it
I like your video,don't know much about battery but i'm going to watch all your videos.
Great idea to open one battery. As this is the a key reason why we users need to do multiple flushes with Epsom Salts as commentors suggested. It is worth at least trying to clean the plates completely and do not give up after one or two flushes. Thanks for posting along with the commentors!!
Baking soda is also good for neutralizing chlorine bleach splashed in the eyes. happened to me while washing dishes at my family's mexican restaurant. Quick thinking coworker grabbed a box of arm & hammer & a glass mixed up a glass full & poured it into my eye, literally sending the stinging agony down the drain. Always keep a box open & handy in your kitchen, you never know...👁👁
The mustang battery was total trash!! If I finish this video and it's good your a magician 🎩
You'll just have to watch and see :)
Great and informative video. But you know how lucky you were that the spark from that open battery didn't blow that battery up and you with it? Very dangerous, open sparks and boiling batteries! I have seen more than one explode and hurt people. Be careful my friend!
I’m not sure what makes you think the battery would explode. The top is cut off and so no pressure can build. The water isn’t going to explode. The bubbles are not the water boiling by the way.
@Dean Clark thank you. Would it ever be concentrated enough for any concerns?
Ok so I just came across this video and would like to explain to everyone that this is all wrong. All you need to do with a dead battery is check the specific gravity of each cell. The low cells if already filled to top you drain as much as you can with the specific gravity tester. You then buy liquid sulfate (battery acid) from the autopart store. Top off each low cell with the new battery acid. Then with a manual charger only set to 200 amps for 15 min, after 15 min let it rest for an hour, repeat this x3 times. After the third time and a hour of rest. Charge the battery with a manual charger for 2 hours. At 20% of the amp hour rating. So say you have a 100 amp hour battery, a 20 amp charger. It you have a 80 amp hour battery 16 amps or 15 will suffice etc. After the 2 hour charge. Let the battery cool and sit for 1 hour. After that charger the battery at a 10% rate of its amp hours until fully charged. The new acid will boil all the old crud off the plates with the higher charging rates just like the the Epson salt has done without weakening the metals from the Epson salt. You do not need to drain all the fluid out of the battery.. just about a quarter by using the SG tester. The new acid will rejuvenate the old acid and distilled mix 95% of the time and bring your specific gravity back up to were it belongs. This is the 1st step.
Step 2. If step 1 does not work and your battery is extremely old you can drain all fluid. Do not flush with fresh regular water. Add hot distilled water and Epson salt mix of 30% Epson salt 70 percent water. Or a quarter of a bag to 1 gallon and top off battery's. Let it fully charge. Then drain to 50% charge. Then again to 100% and repeat x5 with caps off and open to atmospheric pressure, then dump Epson salt and distilled water solution out completely, flush with distilled water only x2 by filling and draining right away x2 , then top off the fully drained battery with fresh brand new battery acid from.the autopart store and repeat the above step 1 process and enjoy your almost brand new battery that should last you another 2 to 5 years. Please note advanced auto, Napa , etc will carry acid other chains like autozone won't carry it. Hope this has helps yall
In response to your other video. I love the start of this video.
thanks
@@CarGroves The protection bit was hilarious. I just watched, 'Reconditioning a 12 Volt Car Battery: 100% Success' and browsing the asinine comments led me to this video. Thanks.
You should use a DC arc welder with adjustable amp control, 5 minutes on and 10 minutes off... About 3 or 4 time... If it's real junk crank up the amps for a few seconds to desulfate
Just an FYI. Those gas bubbles are hydrogen and can be very explosive from just connecting or disconnecting the battery while charger is plugged in.
Its in a 2400sqft shop with 20ft ceiling with roof vents. Do you suggest a bomb shelter?
@@CarGroves 😆 No brother but hydrogen and a lead acid battery can easily mame you if exploded. Happened to my uncle while he was disconnecting a charger with the caps off. ...Just sayin'...
@@CarGroves all it takes is a spark from taking the clamp off the terminal to ignite the hydrogen and the battery could explode. You've gotta keep the fan going to dilute the hydrogen. Another suggestion: connect a short piece of wire to each teminal and have the other end below the terminal then connect the charger to that end of the cable below the height of the top of the battery.
Hydrogen, being light, rises up and away from the possible arc when the batteries are disconnected and disconnected.
@@James-vq9nc Guys, again, its a 2400sqft shop, roof vents, and fans blowing. Everyone lived.
Great safety information. Thanks guys!
One of the best videos on that subject!
Thanks for watching Marco!
A lot of work was put into this subject, definitely looking forward to this one
Thanks for watching!
can we get an update on how long these lasted/ are you still using them?
297.9987 days
Are you being serious, or are you joking around?
@S U I have three batteries in daily drivers that have lasted at least 1 year
would love 2 see u start the mustang! the charm this old rusty piece of love emits is so freakingly outstanding.. greetings from eastern-germany..
Have you thought about replacing the negative plates with carbon plates I have read some really impressive thing when this is done right crazy high cycle life
Another quality video, my friend. I need to do this to a few batteries I have around. Hope you're well.
Doing great. Just knocking out rust repair on the Cougar. Picked up a parts car and hope to be able to have the Cougar up and going soon.
Good vid, but I must mention for safety for anyone watching this for advice that you're not using the charger clamps correctly to connect to the battery. Most likely that's why there was a spark when the charger was turned on.
Thanks for the info!
Then what would be the correct way
Digital CCA testers spoof old-days' resistive load tests by guesstimating internal resistance (clamps on posts being a major source of error when you're talking milliohms) and extrapolating. The best use case of a digital CCA tester is to convince your customer, as you work at an Autozone, to buy a new battery when they don't need one. I bought one and used it for a bit, but ended up throwing it in the trash after it recommended every customer get a new battery when I used it to test batteries with their oil change. Now I just roll my 1970's Snap-On resistive tester across the shop and offer double-check diags to customers when Autozone's convinced them to get an Optima Red-top that'll only last for 3 or 4 years.
Thanks, dude!!! Love the haters! That’s all I can say. You’ve just done a great charity! I can see you take people’s dumb comments with a big ol’ pinch of epsom salt. Stay salty my friend. You are the light of the world and Salt of this world. Keep letting it shine and Happy Easter, bro!!
Thanks buddy lol
great videos. keep em coming. question: after you stripped off the scaling with the epsom salt solution, do you flush out, then add the battery acid? very curious. please, and thank you.
So it's 1 gal distilled water, then 4lb bag Epson salt how much acid then didn't catch that. I enjoyed your video Thanks
Thanks for watching
I noticed you used a _CEN-TEC_ product for checking batteries. A Harbor Freight brand for around $70. Here is a review of that product on their website from someone, if interested: "I am an electrical engineer and auto enthusiast/former tech, so I will give you my observation with this product.This a conductance tester that uses a 4 wire connection(top and bottom of jaw are wired to different circuits). The idea is to measure the internal resistance of the battery, and estimate its capacity. Measuring a very low resistance item(like a wire for example)is impossible. Your meter will just read zero(the resistance of the probes). So the solution is to pump about 1 amp or so of current into whatever you are measuring, and then measure the voltage across the terminals, and compute the resistance using ohms law. This can give you internal resistance down into the milliohm range.So this device does the above, possibly using AC waveforms. All real world powersources have a hidden internal resistance. If the resistance increases, the CCA decreases (the amount of CURRENT it can deliver). So the device has a tiny computer that can compare resistance to an internal table of CCA capacity.In theory it may work well, and many batteries are warrantied because of the results of such a test. However, here are some observations.One is a sealed Lawn tractor battery that you can buy in WM or AAuto with 275/230CCA. It wasn't starting an old tractor. Charged it a few times, ran it thru a desulfate cycle. Voltage levels off to 12.45V(not so good). Tester says 165CCA, which is still kind of ok, should at least be able to turn the engine. The battery barely barely turns the engine 1/16 of a turn, then buzzing the solenoid, and the voltage drop when starting is 4.6V. So, technically the battery is ok according to the tester, but the real world says otherwise. After many starting attempts, the voltage dropped to 12.2 (at this point I know the battery is done, no need for a tester), and the CCA computed by the machine stayed around 160.Next case is a 9 year old big BXT-850 motorcraft in an explorer. 850 CCA. Truck is stitting for a few weeks, hook up the unit and it says the battery has less than 100CCA(bad battery). The voltage was 11.6 according to the tester. The charge may be low, but the truck DID START in a few cranks. The issue here could be other loads and computer drawing current. This could give false readings on some cars that have computers. A Lincoln I have takes 30 minutes to completely shut down all its computers and draw minimal current(even opening a door or inserting the key activates some equipment). Testing on a car with computers, lights, and possibly dirty terminals could give misleading results. So, like the instructions say, you have to wait until you are sure there are no loads, or remove the battery. Not so quick then....The unit has a frustrating interface, and it is hard to get the digits to advance. C'mon, this is 2013, buttons should work. I had electronic toys in the late 70s that worked better. Also, when you connect to the battery, there are noticeable small sparks at the terminals, since it powers up immediately. Not good. We all know batteries produce hydrogen when charging.Here is how to test a questionable battery:1) Charge it up2) Let it sit 15 min or run the headlights for 2 min.3) Check the voltage, should be around 12.6-12.74) Crank engine, voltage should be over about 9V5) Alternator should put out about 14VIf the car still don't start, charge it up again and repeat the process. If it fails, the battery is done.Should you buy it? The jury is out. Similar units are used by pimply faced teens in the auto stores to warranty batteries. I wouldn't use it as a sole determination of battery health. It is probably good to confirm condition or use as a starting point..."
If you really wanted it to boil and break loose the crud your supposed to use baking soda, while your asking water and dumping it out. Now you've only dumped out what was already lose inside the battery and it isn't going to last very long at most a year. But if you boil it out with the sofa then you'll be set for four plus years unless the battery was just far gone to begin with. My dad always said if your going to do it, you owe it to yourself to go ahead and do it right so you don't have to do it again?
Todd, there are many ways to skin a cat, bet your dad knew that too
Actually there's a million ways to skin a cat and they're all fucking wrong.
Thanks Excellent Vid. At any time do you ever put battery Acid back in?
Yes, I would put the used acid back in when you are done restoring the battery.
Adding this information in your video would make this video more complete.
@@SuperBigRol yes of course
Why did't you mention this information on your video? I searched about it alot.
That's what I'm thinking and my state you can buy the battery acid at the auto parts store for like $7 seems like it would do much better with that versus the Epsom salt and water which could freeze in extreme cold
Great video. First time viewer. You get to the point and i dont struggle to stay awake like most i watch. First time also reading all comments and replies. Big question; how do you put up with these assholes that dont comment on your video that gets to the point, but leave comments about the background; ie sandals, water run off, your cars in the background, the color of your f*****g gloves, etc. You got tough skin. Keep up the GREAT videos. "New Fan"
Thanks for watching Mark, I find it easier to laugh at them then get mad haha. Its easy being an arm chair quarter back, not so easy making the videos...
Also, you perhaps shouldhave the baking soda already mixed up in a large basin, ready to use.
I've responded to people who have had battery acid splashed on them..., and the last thing that they wouldhave been able to do, would be to calmly mix it up after the incident. No joke.
Everyone has their own personal percentage of risk they are comfortable taking. Some people are ok in flip flops, some need a full bio hazard suit. Only you can judge how safe you need to be.
That is a good idea, but not baking soda - use water. The acid is not that concentrated that it will hurt you - even on your bare skin - it won't even destroy your clothes immediately - it always waits for awhile, at least I seldom notice it until after the clothes are washed once. No amount of baking soda will stop that.
Baking soda on anything else where acid is present is almost as dangerous in the acid because it reacts making heat. The last thing that you want to do is put more chemicals into the fray if you are splashed.
The main reason for keeping water - distilled or not - available is to keep you from putting your potentially acid soaked hands up to your face to wipe your eyes if you splashed your face accidentally. You should not put baking soda anywhere on your body if there is acid there. At least I sure would not, even on clothing. If you are splashed with acid and can reach a working water hose, it would be better to hose yourself down.
Great video!
I've seen some use the technique of using baking soda to clean the battery first. Have you tried adding that to your process? Also, are you using any of the original sulfuric acid that you dumped out with the epsom salt mixture?
Thanks for the video! What do you think the success would be without replacing the factory acid with epsom salt solution? Have a little 700 CCA that currently shows about 350. Thinking of just discharging/recharging it several times with an inverter + load, but leaving the acid in it.
It should be with the acid. Just pour it out. Flush with water and baking soda, than put the acid back. It will be in mich better state
Have you seen any of the " boil your battery" videos, and if so what are your thoughts?
ok when do I add/replace battery acid? and do I mix with the epsom salt solution or do I dump out the epsom salt solution and replace with battery acid?
Dump the epsom solution. Flush with distilled water. Add acid solution. You can run with salt solution but capacity will be lower as I understand it.
Use a SG tester and if it is greater than 1.1, i keep it. I will evaporate the water off and increase the concentration again. anything less than that is essentially water and you can just dump it. once empty, rinse out at least 5 times, or longer if you keep getting "sand" coming out. This is when the Epsom salts goes in and you put it on a trickle charger... let it sit 2-3 weeks and check the voltage. If it less than 13v wait another week. I usually wait till it cycles and gives me a 14v max. Then empty out the salts and rinse it 5 times again. I have access to 6 quarts of 30% (1.26 SG) battery acid for like $20. I fill up the cells with this and the leftover that I reconcentrate. I also filter it out so there are no other solids in the acid. And you're done. It should test full CCA at theis point and you can put in your car!
You should try flushing them out with a baking soda solution before you the salt solution in it will clean your plates better it worked alot better for me.nice video!!!
_Alot_ is a town in India. _A lot_ is more than 1 of something.
... Great video !!! Thanks for making it, I really appreciated it. I am a little confused, (nothing unusual !), about the last part..... Did you drain out the "Epsom Salt Solution", (Magnesium Sulphate Solution), and put the original sulphuric acid solution back in ? Logic suggests to me that as premixed acid battery electrolyte solution is so cheap, it might be best to return the renovated battery back to factory chemical specs. ......... I did a bit of research and discovered the Magnesium Sulphate dissolves the sulphation on the plates, but I was amazed to see that it also worked as an electrolyte and permitted the batteries to take a charge. I'm very curious to know if permanent replacement of the original sulphuric acid electrolyte with Magnesium Sulphate would harm the plates over time. Thanks once again. :-) Chris (in Brazil).
I have a 2016 honda civic battery 51R drop voltage from 13.2 v to 10.57v overnight. I decided to recondition the batter. I used baking soda to clean it twice and flush water thru the battery at least 5 times. In 5 times fill the water shake the battery.. the water came out very dark. Finally i fill out epson salt 15oz with 1 gal hot distill water. I used battery jumper to initial charge after 1 hr I measured 12.2 volt with 40% of charge.. I just wonder why it comes back so fast within 1 hr...any idea... I do not have crank CCA tester and do not know what CCA at this moment. Going to buy one battery tester.. This video is awesome I learn a lot from you... very appreciated. Will update my process soon
Start it and go drive it around, it will charge faster
So essentially your turning the battery into a electrolysis tank to clean the plates then puting the acid back in. Can we get exact measurements of solution to acid on final product
Just dumped it all out and added the same acid back in
@@CarGroves So you reuse the acid you drained out and I assume added new acid to bring each cell to the proper level? Why not just put in new acid? The old acid surely has debris in it I wouldn't want to put back. When the old acid is dumped out it has sediment in the bottom of the container.
Is Epsom salt the best cleaning solution to desulfate the lead in the battery?
I would use high amp spurts to run though the Epson salt or some other cleaner solution,,, electrolysis to desulfate the lead plates at short intervals. I don't think the Epsom will clean well just soaking short time.
Then flush it out with tap water, then a final rinse out with distilled water. Then a final fill with a proper battery electrolyte from the auto store. Then charge. Good idea the baking soda in case the pouring hydrochloric acid spatters onto my flip-flops.
THANKS for doing this! Im doing various things w (4) batteries. Im still not clear on the purpose of epsom salt.....other than perhaps as a flushing (medium)?
So any update on longevity of a battery reconditioned in this manner?
What would be the results if after cleaning and charging using epson salts in was then cleaned out again with water and then refilled using the original filtered acid.
Enjoyed all yr tutorials and thank you for that but can you tell when draining the bateries in the bucket its not harmfull or dangerous not to use gloves? Noticed you do this with and without gloves? But this is a great video. Thanks from Amsterdam
You can google acid on skin
The drain line for your house air conditioner gives you free distilled water. Not that its expensive but still. Free is free.
Quality video, awesome explanation! Thanks for sharing!
Hello I'm sat watching the sulphate bubbling from your plates. I watch , "the house that never sleeps" complete similar process the biggest difference being he used the bicarbonate of soda 10oz to 1 gallon of water which once placed in he vigorously shook rolled an tousled the battery etc etc before decanting a filthy liquid! Then like you refilled with distilled water and Epsom salt then he charged with an old dumb 1amp charger for 48hour. I dont know if I explained well enough and would advise watching it for yourself to understand the level of filth that came out from the bicarbonate mixture. Would love to hear back if you try this. Thank you for the video
Thanks for watching. Getting old the old gunk out would help a lot.
Great Video. Are you mixing old acid with Epsom salt water and fill the battery here?
Does it matter how deeply I discharge a newly reconditioned deep cycle battery? I used a trolling motor to drain it completely after a successful first charge, but now my charger says it's failing to re-charge. Did I drain it too far? Should I start over? Thanks for the videos as always!
No idea
have you tried using a battery charger set in boost mode (200Amp) for 5 minute intervals with 1 hr reset in between? with caps off and topped off with distilled water before beginning.
200amp seems like an explosion waiting to happen
Great info. Thanks
Were you not curious to dump the Epsom salts and replace them with sulfuric acid? Perhps there will be a problem with Epsom salts and longevity? I would love to know how regular battery acid works inside the battery when compared to Epsom salts and also how much luck you have had with these batteries in the cars since doing this.
Still not happy about how you dispose of your lead juice. Perhaps you should evaporate everything in a large shallow tray and then melt down or dispose correctly of the lead.
Yes! Battery acid should be put back in, not epsom salt
Great video trying to show how to rejuvenate old battery's, but lacking mixture specs on BS + EPS...
Also poor display of safety, handling outpouring of the acid with NO safety glasses and bare feed in thongs??
google it
Very informative.

Thanks so much.
No idea
Love the ppe!
:)
dudes got his covid gear squared away
1 think the discharge and re-charge will work. But what voltage are you charging? You need high voltage desulphate e.g. 20v, 0.1A. So using smart charger may not work.
5 amp
Great Info, appreciate it very much, but if you could condense it to about ten min. Would be better.
Thank you
this means you threw away the old acid from the battery and replace with epsom salt solution and charge and discharge to remove dirt by keeping replacing new epsom salt solution until the charge is back up to maximum level of that amp meter reader thing u talking about... i hope that is correct
You need to buy a Stanley smart charger. They won't just say"bad battery" but actually bump into a recondition mode. Then start charging when done. The recondition mode desulfates the plates. When combined with the EPSON salt treatment, these batteries should be new.
I'll look into this, thanks.
People who do a job that claims to be creative have to be alone to recharge their batteries. You can’t live 24 hours a day in the spotlight and remain creative. For people like me, solitude is a victory.
Need to flush 4 times with baking soda and regular water, about 10 oz baking soda mixed with 1 gallon water, and yes you need to shake the battery around to get the solution everywhere inside the battery, after the first time you drain it, it will totally be safe to handle. Then follow up with the Epson salts: Mix 12 oz with 1gallon HOT DISTILLED water ,dissolve salts Completely. Now,Trickle charge 36-48 hrs. Then Discharge to 5-6 volts, do this at least 3 times , after that the best way to charge is-- caps off , 200 amp charge 15 min, disconnect, let sit 1 hour.. Do this 4 to 5 times ( be sure you add Epson Water as needed to keep just below the caps depth.) If you do not have a 200 amp charger increase the charge time as needed. This will REALLY work in all but the very worst damaged battery. The 200 amp will quickly de sulfate the plates. I have used a 50 amp increasing my charge time but it takes so long. Good Video and kudos for all the work you put into it. If you do not want to try my method use yours but add the baking soda flush and be amazed at the results.
Thanks for watching, might give this a try next time.
What do you think about dumping out the epsom salt solution after the voltage and CCA have been maximized using your process, and then reloading the battery with the filtered battery acid that was initially removed from the battery?
when i was young dad would put baking soda in make me roll it up and down the drive way risne repete add new jucie work for another year
Would mechanically cleaning it with a toothbrush and isopropyl alcohol help get the sulfate off of the surface of the lead plates?
The bubbles you are seeing in the battery is hydrogen. Very explosive. you are not cleaning the plates. ( I worked in a plant years ago. When a battery goes bad, the plates short out in the bottom of the battery from lead oxide falling to the bottom)
Did u mix the salt water with the acid or do u put salt water only?
First, I'm not trying to be an ass..., just concerned.
After your new video on the process, I still have one question...,
What did you do with the fluid containing the heavy lead sludge & acid?
Lead doesn't just go away, it's forever, my friend.
Dangerous to have it residing in the soil where you or your kids can be exposed to it..., for years.
I baked a cake with it, passed easily 2 days later.
@@CarGroves I'm surprise you still got a ass hole?

Someone did a video where they charged their battery after doing this at 200 amps. This energised the plates and helped clean them
I wouldn't do that, thats a dangerous amount of amps. Im sure it works, but...
sweet project cars
I watched that video, too. The guy didn't charge the battery at 200 amps, he put it on a 200 amp charger. The actual charging current is a function of the current capability of the charger, the electrical resistance inside the battery and cables, the battery plate size, and the charge of the battery. You can't tell what the actual charging current really is unless you measure it. This is why I went to this Car Groves video, but he doesn't get too detailed either. Plus, he never said if this trick will restore a battery well enough to start a car after the battery sits for a week. I tried the epsom salt trick, and it didn't work for me, but I didn't try repeated cyclings. I was always told that you do permanent damage to the battery every time you run it down like that. Now I may never know if this actually works, or if it gives false hope, like every other video out there.
After putting Epson salt and water in and charging and discharging what do you do after that do you keep the epson salt and water in or put new sulfuric acid in?
I would put the acid back in.
@@CarGroves why wouldn't you then do your final CCA test after you add back sulfuric acid?
@@AlanBaum because it doesn't effect the CCA reading for the video. Everyone wants every possible detail covered, the problem is thats a 3-5hr long video. Instead of picking apart others work, I suggest testing on your own...
@@CarGroves Hey, no problem, just trying to understand the science behind lead acid batteries w/o the acid. I would think that is vital to the chemistry for the electrical power. Does the Epsom salt and water solution convert to sulfuric acid after a charge?
@@AlanBaum there are many ways to hold a charge, acid is just one of them. en.wikipedia.org/wiki/Salt_water_battery
Hi,
once you finished with the epsom salt solution and you cleaned the plates do you have to empty it and fill it again with sulfuric acid solution?
(great video)
Yes
@@CarGroves Hi, ok so you got almost 85% of CCA out of the open battery, with only Epsom Salt water solution right? So why would you put the battery killing Acid back? It seems counter productive to me.
Do you have to put the acid back the battery

Gonna try this on a battery here shortly. Years ago my dog chewed thru a trickle charger cable and my dad hooked it up in reverse. So I take this 3 year old interstate battery from my new to me e30 and reverse charge it from about 4.0 to -8.0 volts. Realize the next day and switch it back, charging to 13.0 volts. 5 years later this battery is only used to move old cars and still works great, unsure of cca's tho.
You had negative 8 volts?
Car Groves lol yes I definitely did. Maybe it was negative 4 to 5 at the most, it’s been a while.
I’m also still wanting to try this with a 5 year old duralast. Whenever I remember to pick up some epsom salt
I know you probably won't see this but me and my dad are trying to revive a battery using this method we have filled the battery with the Epsom salt solution and put it on a trickle charger however we cannot get the voltage to move are we doing something wrong it will also not charge up on a regular charger
Try dumping out the crud and putting a fresh batch in, seems to work better with higher voltage charging
What type of plastic is the plastic bucket made out of that will contain battery acid? Also... Why don't you filter the lead out of the battery acid ?? And reuse it
