Reconditioning a 12 Volt Car Battery: 100% Success
HTML-код
- Опубликовано: 4 июл 2024
- I take 4 junk 12V batteries and bring them back to life with a combo of epsom salt and used battery acid.
I've now done a part 2 with a cold cranking amp test and opened a battery up so you can see the process. Link below,

Don't take this wrong, but you almost sound like Jesse James, but almost look like Kevin Smith (Silent Bob). Really that's kinda legendary lol. And thanks for the vid, sir this is good stuff.
Haha Thanks, I think?
He honestly just looks like a genuinely good dude right?
Thank you
How much old used battery acid do you mix with a concentrated Epsom salt solution. What proportions? Also , once the battery is restored do you leave the Epsom salts and battery solution in the battery and continue to use it like that or does one discard that mixture once battery is fully charged and refill the battery with fresh clean acid?
You all probably dont give a damn but does anybody know a tool to log back into an Instagram account?
I stupidly forgot my password. I appreciate any tips you can offer me
Hi all. I'm a mechanic of 27 years. Not everything in this video is correct. If you have an old battery, I can give some simple advice. ( But be assured, the battery will never be like new). You MUST use a "load tester" first, to document the condition of the battery. NOT a Multi Meter, but a LOAD TESTER, that you dial the correct CCA (Cold Cranking Amps) value of the battery as displayed on the label. Once you document the poor condition of the batter, now it's time to recondition it. 1) remove car battery and place is on soft ground such as your lawn. DO NOT open caps or remove any acid yet. 2) Roll the battery around over and over for several minutes. use your boot and kick the battery and make it tumble for a few minutes (this rough contact breaks a lot of the buildup stuck to the plates). 3) Drain all the liquid into a container holding the battery upside down to drain it all. Keep this acid and allow the dirty looking liquid to settle over a few hours, This will take time until the sediments settles to the bottom of your bucket. 4) fill battery with water and repeat process of rolling it after putting caps back on, but DO NOT keep this liquid! instead, dispose of this waste. 5) Once battery is empty again and the captured Acid part 3 has settled and looks clear, carefully pour the acid into another container, leaving lead sludge behind. Finally top up the batter with the clean acid and test the battery on a "load tester".. Yes you can charge it, but prior to doing so, test to see if there is improvement. I recently done this to a Pajero V6 Petrol, that had a dead battery. The Battery bounced back and I got 6 healthy months from it, but eventually it failed to hold a charge. No Epsom salts used in this process, however I am sure that will only improve the condition to perhaps give you as much as 12 months of life out of it, but I cannot verify that as I haven't used salts.
You are correct, The trick is to get the stuff at the bottom broken up and out of the battery. That alone (if it causes bridging) can cause the load tester to give a thumbs down so I am not sure what you would gain by using the load tester first. I am not an expert by any means!
Your a mechanic you know well you should just change the battery come on for god sake all that pissing around and then the thing leaves you down at the worst possible moment. If you have got time to this and earn a living repairing vehicles I tip my hat to you sir. 👍
@@Blaaggarding this information is valuable and important to know and I'll give you an example. I was working as the mechanic on a remote stretch of hi way on the Nullarbor in Australia. Known as the worlds longest straight stretch of road. This road consumes many cars that were not prepared for the drive, and "the Car Graveyard" located 2km from where I was working, was full of perfectly good cars, with damaged engines. One day a Toyota 4X4 with a flat battery that couldn't be charged broke down nearby. The two young backpackers driving it was freaking out as they needed to get back to Perth to fly home in 5 days, Yet where we are, it will take a week to have a replacement battery sent in. This is when that knowledge is valuable as I did it to their car battery and got them to a point where they could start the car with ease each time, and keep going to complete their last 1400km journey. I certainly do not advice you do this trick to a dead battery and then rely on it like these people did to cross central Australia through the desert. But for their needs and the fact they had little option, it worked 100%. But you are correct, ALWAYS replace the battery and be done with it. Peace of mind is important.. Women will NEVER be comfortable with a quick fix like this. They freakout at the very idea that their could still break down. Men, love the challenge hahahaha

Why would anyone use that old acid out of the battery why not just put new battery acid in there with the distilled water
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
The true test is fully charging those batteries, then run them each with e.g. 20 A load (e.g. 4 headlight bulbs in parallel) until the voltage gets down to 11.0 V. You can then compute the total energy released to figure out how much capacity you end up with (basically the longer it takes the better the battery is). Simply being able to load the battery to correct voltage doesn't mean that you can do anything meaningful with the battery. A good car battery is rated between 50-120 Ah as new and if your reconditioned car battery has 2 Ah, it's practically not usable for anything even if it technically still works as perfectly good 2 Ah battery. If you truly just need 2 Ah battery, you should use NiMH or Li-on batteries instead.
@@christianpowerssavesthewor8404 The 12.58 V that you measured is voltage. When you run the starter you need power and for that you need current. The power is literally current multiplied by voltage.
The problem is that when battery is bad, the voltage drops rapidly when you try to drain practically any current.
A simple test is to measure your battery voltage like you did and then turn on the headlights and turn the ignition to "ON" but not try starting the car.
Then measure the battery voltage once per minute.
The current needed for the headlights should cause less than 0.01 V drop per minute (but the drop from 12.58 V in this example to headlights on state could be e.g. 0.3 V even with fully functioning battery).
The reason for this is that the total energy stored by the battery is limited by the lead surface touching the electrolyte. With damaged battery needing reconditioning the lead surface is damaged and cannot react with the electrolyte over (large?) designed areas.
As a result, you get expected voltage but the total energy is very low so draining any current will drain the energy fast out of the battery.
Again, energy is literally power multiplied by time. So the above test with headlights on is actually draining energy from the battery and the voltage drop is used as a proxy to estimate the remaining energy in the battery.
You can imagine 12.7 V meaning "100%" and about 10.7 V meaning "0%".
@@MikkoRantalainen
Thank you for the explanation, I didn't know when he use the boil distill water because it looks to me he still refill the batteries with the same electrolyte removed from them.
@@Brooslinks Oh, you do need to add any lost water but also the part of the lead surfaces that's always submerged get damaged over time. And all the damage there cannot be recovered, no matter what you do and that's the part of the damage I meant above. The parts that are not submerged obviously do nothing for the energy storage so you always want max amount of distilled water in a lead battery.
Old skool tech
@@brianlitecky9798 Definitely. Lead batteries were invented around 1859 and the only thing that has changed is purity of the materials used. The less contamination you have, the longer the battery can live.
Of course, the body of the battery is nowadays plastic instead of glass for obvious reasons.
My car battery would not hold a charge but the cells tested fine. Put a tbsp of concentrated Epsom salt water in each, trickle charged overnight. Battery lasted fine with no problems and I sold the car three years later. I did not flush the battery or anything. My Dad did his lawn tractor battery the same way - still acting like a normal battery after 4 years.
Thanks for the comment!
Thanks! Like anyone researching any subject, I can take parts of your information and combine it with other videos, current knowledge, comments (neg and pos), and find more resources to double check safety and make my own informed decision. Having the guts to show your methods helps us all learn!
ruclips.net/video/RNnSYuTuLk4/видео.html
That is one of the most wise comments I have ever read on any how to video. thank you for sharing those super positive and wise words about how to look stuff up online. Feels like some people forget that's how you do it lol
Just looked at your video. And I enjoyed watching it! So many of us who owns cars, trucks, motorcycles, etc., for transportation, always thinks that when batteries goes dead, you must always spend more money again to but a new one. I've revived two very old batteries that were dead, by just hooking a 20 watt solar panel directly to them without a solar panel controller. And BOOM! Batteries still works, installed, and started a Dodge Caravan. And the other one is a backup. Someday I'll try your trick, and let you know how it works out!
Thanks for watching
George, how long did you leave the battery hooked up to the 20 watt solar panel? Thanks, friend.
I have some dead batteries and I am going to try that trick to see if it will work on the ones I have because I am tired of buying batteries for my vehicles and lawn mowers. Thanks for the tip and I am glad to have found you and I believe my charger will work on each of them and hopefully they will work again.
The coating in the battery is sulfur oxide. The metal looking debris is mostly lead and some of the steel grid that is imbedded in the lead plate to hold it all together. The Epson salt trick works 1 time. It somewhat removes the sulfur oxide, but over time will deposit magnesium into the plate.
If it works, it works.
At either rate, the batteries are worthless to begin with, so if it’ll buy a even another year or two. That’s still a win win…
Thank you so much for taking the time to not only simplify, but also thoroughly explain the internals and operation of the batteries! Your explanation gives the viewers a better visual idea of what they're working with, and what they're trying to accomplish. Great video my friend, very informative!👍🏻
I've been doing this for 20 years with batteries found on the curb, I haven't bought a battery for 20 years
Where do you get the acid from?
Thanks for watching!
Where do u find batteries on the curb? Most battery places make u exchange or pay more
Im currently working on mine bug I think 1 of th cell died. Any way to save it?
Michael Garcia advance Auto was running a deal for every used battery you would trade in they would give you a $20 gift card. It had to be a car battery it could not be a lawnmower battery or a motorcycle battery which my motorcycle battery cost me $140 and did not last a year from advance.
Nice video, thank you ! your time & adventurous kindness is beautiful
Please let us know if your batteries were able to work. Showing a good number in the voltmeter does not means they may crank a start either they may hold the charge... Please let me know. Thanks again. Next time be a little more careful with your eyes and your stinky feet. Thanks to God for people like you...
Glad you enjoyed it!
*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*
do explain how you got a AA open to add epsom salt water
Not!
Yea aite
Bullsht troll. This exact posting is seen on all battery restoration videos. Go crawl back into your toilet liar.
I tried doing this two ways. The first one I did I did it exactly like you did it but I used sulphuric acid because it was only $15 for 5 L. The second way I did it was I just drain the acid and then I refilled it with fresh sulphuric acid. I found your way works best. You really have to get that old crap out of the battery for it to be able to except and hold a charge thanks for the video I found it to be very informative peace out
Thank you very much. Great info!
ruclips.net/video/1Ut53ma4Gko/видео.html
I followed your advice and did this to my battery in my Jimmy. It quit holding a charge and would die after sitting a couple hours. Now is starting my car after sitting overnight. So cool. Thanks bud!
Thanks a bunch will be trying this before buying a new battery.
Man you're amaizing 🙏
At the beginning of the video when you talked about voltages, a 10.8V battery is a totally dead battery. A fully charged Flooded Lead Acid (FLA) battery reads above 12.6V...sometimes 0.1 or 0.2V higher. And a voltage test indicates the state of charge of a battery but not its health. You need to do a load test and a capacity test, the latter is time consuming and you need to use specialized equipment. Its all fun though.
Great vid...thank you for posting!
Loved that joy u had at the end, starting your ATV. LOL
Looks good , interested to see if there is a volt drop over night
Great video, knowledge and safety is so important . My dads a marine engineer. He is a specialist with batteries. He loves his distilled water and Epsom salts. Great job😊👍🏽
Thanks for watching bill.
ruclips.net/video/RNnSYuTuLk4/видео.html
But he didn't know what he was doing.
I've seen a lot of folks do this battery restoration. I'd love to see a load test on the battery to gauge the capacity. I know it's not going to be perfect like new, just curious what percentage capacity has been recovered?
I have load tested an 800 amp starting battery with a 500 amp loaded tester. I tested the battery several times before recharging it the electrolyte specific gravity test show the acid to be in the high range before recharging.
Video 2
The open circuit voltage taken on the battery terminal does not indicate any capacity. Volts is potential, capacity is rated in VAh or Volts times Amperes multiplied by the time the load is applied.
Would of liked to see a load test on all 3. But good job restoring them. 👍
sulphation is the killer, sediment settles to the bottom and shorts out the cells. After bathing the batteries in epson salts( for an extended period), and a thorough flush, use distilled water, and proper amount of sulfuric acid to fill the cells. Don’t use the old electrolyte! You won’t be able to remove all the sulfation between the lead plates, but some more limited service of these used batteries is possible. The capacity and cranking amps will still be compromised. Worthwhile to do IF the batteries were not frozen when discharged, and no bulging or distortion of the lead plates is visible. cheers!
Obviously new acid would be ideal. I was just showing how to do it the cheapest way possible. Thanks for watching!
right, of all the assholes in the comments at least one person was able to be objective. if the plates can be cleared and new clean solution added some service can be restored.
in my mind, i think this process in combination with a large capacitor for extra cranking capacity is a pretty good solution.(then once failure takes place, find more dead batteries, rinse/repeat but obviously the capacitor would still be good)
Great video. Thank you. One note - Baking Soda and/or calcium (generally basic in solution) to neutralize acid may work, but vinegar wouldn't, Brotha. Vinegar is just another acid, albeit weaker than the sulfuric acid in batteries.
Got it
You forgot to show how much battery acid it just skips over that particular part what's up with that need to know how much battery acid you were mixing with the distilled water Epsom salt solution
Thank u car groves for your tips.
Nice once and useful info, thank you...
Glad it was helpful!
This is awesome, thanks man. I had a dead battery but after watching this I never bought a battery again and the dead battery was alive again btw I watched part 2.
Same here also watched Part 3
Thanks mate, I am now a subscriber and I have the same safety shoes:)
:) Thanks for subscribing! Safety first haha
@@CarGroves Thanks for the Video clip! Sorry for chiming in, I would appreciate your initial thoughts. Have you ever tried - Rozardner Powerful Battery Reality (search on google)? It is a great exclusive guide for learning how to recondition an old battery without the hard work. Ive heard some awesome things about it and my close friend Aubrey after a lifetime of fighting got amazing success with it.
I like to wear a full face shield with my safety glasses whenever I mess with strong acids or Alkaline solutions. Acid in the eyes is bad. Lye, which is a strong alkaline (basic) will quickly blind you. (For an eye wash- Keep some baking soda when messing with acid. Keep vinegar when messing with Lye. )
Good video. Thanks
I have done this with a 12 year old interstate battery that was totally dead after sitting in my pickup truck that sat for over 5 years unused and it worked the battery was just as good as the day I bought it , it had full 12.5 v and I had no issues with it my truck started just fine for many more years ..This is real so save your money and try it before buying a new battery and yes I has tried charging it a few times long before I tried this with the battery charger it got up to 10.2 v but wouldn't even hold that for more then a day...this really works I poured out all the acid into a clean bucket added distilled water and Epsom salt about half way full then poured the acid back in to refill the other half of the battery ..note keep baking soda near by to neutralize any acid spilled or left over..goos luck everyone hope this helps
Thanks for watching and experimenting Richard
Was just talking about this with some neighbors. Dude said his Dad always flushed/hosed out the junk, refilled the battery and charged it. Old school repair for old school charging systems maybe but when I think of all the money I’ve spent on batteries I really want to try and repair one. Just for the experience. Thanks for validating our backyard mech discussion
Thanks for watching Ken!
Protip, don't dump out sulfuric in to a bucket acid while wearing flipflops and sweat pants. Also have a bucket with a baking soda solution to pour on you if you have a mishap
I'll take care of my own safety, thank you.

About 12.74 - 12.6 v volts fully charged battery. Approx 12.40 is 50 % ! Some ecu's go into limp mode as they don't get incoming voltage . Running it should read 14.4 v - 13.7 V approx. Even with lights / heaters on
Yes with an alternator charging it, new batteries come 12v
@@CarGroves - at 12v a lead acid car battery has only 25% of it's charge left. A properly charged car battery is approximately 12.7v.
@@flyingdutchman6984 And for that reason: A "fully charged" battery having only 11 volts (without any load) = good candidate for the trash can.

How many times can you repeat this process for each battery, how long does each battery hold its charge??
Thanks for the Video, very USEFUL..Thanxs
You are welcome!
Cheers and take care
Getting a battery to come back is very tricky. I have the top of the line charger from Harbor Freight. To see if a battery is doable, do this: Top all the ports off. Maintenance free is still toppable. Most of the time the cells are low. After 10 minutes of charging in AGM mode, do this test. (AGM mode with remove a short off a cell most of the time.) Take a multimeter, go to +, and read each cell with the probe tip stuck in the acid working towards -. If you get at least 1.8 volts difference between each cell, it's doable. Charge at 8/10 amps standard battery mode for 8 hours. Load test the battery. If it dies quickly, drain the battery & add fresh acid. Can be purchased at an auto parts store. Recharge the battery again. It should come fully back & hold a charge. I didn't add epsom salts or cadium tablets & had success.
"Top-of-the-line charger from Harbor Freight" lmao. That's like saying you selected the finest cut of beef from Taco Bell
I'm not sticking my multi-meters probes in the acid.

Good job 👍
after reconditioning the batteries how long do they work before going bad again
You use distilled water for you solution, but you rinse your batterys with a garden hose with city water, then put old acid in.
If a battery reads 12v doesnt mean it will crank a car.you need a load tester. Ive done this with batterys before ,sometimes it works. But never for very long. If you live where it gets cold in the winter, it wont work a all.
Thanks for the info
David, for flushing you could use old pond water, it doesn't matter.
12v is basically a dead battery when talking about cranking amps.
Anywhere from 12.7v to 13.1v usually a fully charged battery.
Where I live the way we test when battery getting too old is when it gets cold. It cranks at 30 degrees F will it crank at 10 degrees? Or even zero F.
Whats the ratio between epsom salt and acid solution may I know? Well if there was that much different in the voltage before -after it just might start a car.
50/50
Kudos for the video content! Forgive me for chiming in, I am interested in your opinion. Have you researched - Rozardner Powerful Battery Reality (search on google)? It is an awesome one off guide for learning how to recondition an old battery minus the normal expense. Ive heard some pretty good things about it and my mate after many years got astronomical results with it.
Oh snap
Finally . A video that shows how to properly charge a battery!!! Just what I was looking for.
Thanks!
Great video
This has been around for years, works good if you just want to make a car run so you can peddle it but not good for long term.
I think its hit or miss from my research
It's pretty much all miss. The people saying it worked have not tried putting that battery back in service. They will find out soon enough i guess
It works great if done correctly and there is no bad cells. You do have to replace the Sulfuric acid solution
what is the proportion of the used acid - epsom salt - distilled whater?
Great video, this is going to save a lot of money! Thanks!
Glad it was helpful!
Good information thanks for sharing
Afterwards, did you use it with the epsom salt solution or did you pour that out?

Nice video, educational, and easy to learned.
Glad you enjoyed it
Thank you for this video I learned a lot I’m gonna give this a try thank you
Would have been nice if you told us what the epsom salts/sulphuric mixture was when you refilled the batteries
I agree - seems like it was 4.5lbs of epsom salt to 1 gallon of distilled water ??
@@TomMcDonaldatYahooDotCom That mixture was explained well enough on video, but unclear was the refilling after draining and flushing the battery. Did you mix one portion of the previously drained fluid, with the H2O/epsom mixture (and if so to what ratio ?) or did you use the H2O/epsom salt mixture only
There's available volts and then there's available amps. You can have 12 volts but little amps and amps is what you need to drive a motor like a starter.
thats what i wanted to see? see them actually cranking an engine over 👍
Well what is the mixture ratio ,do you leave the Epson salt in it? , do you add more acid, do you mix the acid with the epson salt and put in the battery cells.
Good explanation good video. Thank you
You are welcome!

I think you need to load test, to really know!
I think you mean lead test, the lawn, before kids IQ drops below coco.
He won't because those batterys will FAIL a load test.
hi everyone ,if anyone else wants to learn about how to restore a battery try Jons Mender Guide ( search on google ) ? Ive heard some incredible things about it and my mate got excellent results with it.
Salt acts as an abrasive and scrubs the surface for you. That totally makes sense. I would shake them gently while the solution of salt is inside wondering why not use some new distilled water with salt but yeah great video 👍
Epsom salt isn't sodium chloride 'salt', it's magnesium sulfate.
thanks for sharing your experience sir. but something i missed here regarding the acid is there any acid been added or just solution of distilled water and epsom salt, thanks.
Voltage is one thing but current delivery is another. The amount of amp hours and cranking amps can't be measured with a multimeter and I doubt they would last
in operation. Sulphated plates cannot be physically cleaned this way as the plate separators are compressed with the swelling of sulphation, jamming the lead sulphate in place.
A tell tale of these un recoverable dead batteries is the bulging of the case, especially at the ends. The epsom salts may clear around the edges of the plates, but you'd be very lucky to get even 10% back.
How does interstate battery sell reconditioned batteries?
@@CarGroves two ways they can recondition them, one is to do production line impedance and load test and reject below a certain capacity, the other is to cut around the case just below the seam, lift out the plate assemblies, pressure blast the cell clusters and clean out the sediment cavity then reassemble, ultrasonic welding the plastic back together and adding new acid before charging. Again, they would be graded before reconditioning and any falling below the standard just get recycled. Car batteries are 99.9% recyclable, so they can't lose either way.
@@alasdair4161 a charged battery has the highest acid level. So if you took partially charged lead plates out and pressure blasted them and put them back in considering that they have some of the acid absorbed or converted into them or whatever. If you added full-strength acid after cleaning the plates and putting it back together wouldn't it make the acid level too high?
ruclips.net/video/RNnSYuTuLk4/видео.html
Alasdair, do they sell lead at the hardware or welding shops? wouldn't it be eaiser for consumers to just buy lead plates and build batteries from scratch?
I was told my Interstate battery needed replaced. I checked it out at home. I had neglected to clean & protect my terminals or check the water level. Addressing the issue solved the problem!
ruclips.net/video/RNnSYuTuLk4/видео.html
Good video. Love the OSHA approved flip flops, that's the best footwear for battery acid protection.
Before you empty fluid out of battery,try reversing the chargers polarity,and tap the post quickly a few times,it will knock off corrosion and plac,then continue with Epsom salt clean and new muriatic acid,if you want to reverse a battery polarity,completely drain 12 volt power and charge the opposite if you need it to work in either left or right to work in you're vehicle
You’re lucky you can still do that in the USA. Here in the UK all batteries are sealed now.
But you’re missing a trick by not settling and then filtering the old battery acid. If you filter the settled acid first through a very fine tea strainer to remove the larger particulate matter, then through coffee filters, you will have a far more extensive process, and end up with a much cleaner, more efficient and longer lasting acid.
It’s those floating particles which have come off the plates, that cause the drop in efficiency in batteries.
Metal doesn't float in acid
Car Groves that is of course true. But I’m not talking about metal - as you should already be aware. The corrosion or scale on the lead is correctly termed sulphate. As I believe we have both figured out, it’s this sulphate material that’s clogging up the battery, shorting out the cells and causing it to become inefficient. So it’s the sulphate that’s floating about, not metal.
Try thinking before typing a comment based upon assumption and insufficient knowledge. Many of the so-called ‘haters’ on here are actually sharing accurate information. I’m one of them.
will a coffee filter work ?
So for what you mixed the destill3d water and epson salt, when using the OLD used stuff to refill the batteries or did i miss something???
He mixed the distilled water/epson salt solution with the old battery acid, before he put them back in the battery.
Thanks for sharing
I will definitely try this method many thanks
Dude, this video was hilarious! Comedy is your thing.
Thanks for watching Brian!
Lots of vehicles will start with a battery fresh of the charger... how do these hold up after sitting unused for a week or two?
Great
That was pretty damn good!
Watch video 2 on my channel.
Thank this battery reconditioning plan t.co/uUSuy6Yk5g for the help reconditioning my batteries. I had Three dead batteries scheduled for disposing of. But I was able to recondition them using this technique in just One hour! It really works for all kinds of batteries!
Thsnks. To what ratio did you mix your water/epsom salt solution with the acid drained from the batteries?
my take is that you didn't clean the plates with the rinse or the epsom , but with the initial 50A charge. Sulfates are stuck on the plates and you'll need high amps to dissolve those precipitated placks on the plates. Usually a good 10-20 minutes on a 100-200A charge until you see bubbles coming out of the cells will recondition your batteries . I wouldn't advise playing around with highly concentrated sulphuric acid. It's extremely corrosive and dangerous if it gets on the skin , it literally slowly burns away any fabric.
and charging that same acid at 200amps is safe lol, pot meet kettle
What is the mixture of epsom salt to acid ?
Thanks for the information
Question, what happens if your battery is still full, should you just empty it and put brand new fluid? It's a battery made in 2010 December that just died last Thursday, my dad paid 400 something for it and I wanted to see if I can fix it, is it still possible or is it too old?
Battery minimum voltage should be 12.5.
They should also be load tested.
Hate to be negative, but there is many ways that a battery can fail.
As a battery ages the lead decomposes and ends up in the bottom. It belongs on the plates.
Even if one can bring it back to life it will usually have low cranking amps or test amps. If the battery gets discharged too many times it can also sulfate.
K Kenason absolutely! 13.5 is the optimal voltage
12.5 volts is the Minimum voltage if the battery is sitting not connected to a charger.
It is a static rest voltage.
Sometimes the battery will be higher if it is pulled off the charger but it will settle to 12.5 or very slightly above within a few tenths if it is good and all the cells are contributing..
New batteries come 12.4
@@CarGroves I'm not going to debate one or two tenths of a volt.
Voltmeters are not that accurate
@@CarGroves ive been a master mechanic for 30 years a new Battery isnt fully charged off the shelf and they should charge yo 13.6 and should be load tested with a battery load tester to show they have the proper cranking amps the voltage doesn't mean nothing when it doesn't have the amps to crank it over , and it looses it's voltage the first time under a load.
Love the safety sandals lol
Samoan safety boots is what we call them in NZ
They are very comfortable

This guy needs to be in hollywood... poster boy for allllll diy nerds... he is what we all sound like inside.... not what others hear but what we hear as ourselves... no kidding...
Ha Thanks!
Thank you very much for the video. Where did you got the acid is it sold on local shops
He recycled the acid that was in the batteries
what was the cold cranking amps (cca) after they were charged?
Try video 2 on my channel

Sometimes it works and sometimes no. Worth a try though.
My thoughts on it too
A few bucks worth of distilled water and a few hours of mucking around is always worth a try to save $90.
Spraying water from a hose nozzle will make a nice pattern on your face when the acid spatters out of the "empty" cells.
It`s surprising how easy this reconditioning steps are t.co/Folp6e7Dkc ! My auto batteries, cellphone battery, drill battery, camera battery, along with other forms of batteries are all repaired and useful again! Since starting this program I have ended up saving over $ 400 on batteries!?
Hello Karen
Thank you....this was very helpful....Take Care!!
Thank you! You too!
Thank you for this very informative video. I myself have 3 car batteries that are dead and will follow your method to try and revive them. One question after rinsing the batteries with the epson salt and purified water solution, when emptied, do you just refill the battery with the old acid or with the acid and water/epson salt solution combined?
Put the old acid back in, watch my part 2 video
Did you try it yet
Volts mean nothing... it's all about the CCA (Cold Cranking Amps) or in other words, how much work the battery can do when fully charged?
Every spring my batteries are dead. Even after using a tender
@@alex124241 check out scotty kilmer on youtube.This guy knows everything about cars
Not true
Totally wrong
No load volts don't mean much, its voltage under load that matters
Liled and subscribed thanks for the video
Awesome job thank you so much brother
Well done, other videos I have seen have restored voltage but the battery still did not have enough grunt to use in a car ..... I will be interested to see a follow up from you on this matter ,,,
A second video is in the works.
Over time the plates get eaten up, the corrosion builds up in the boron and shorts out the plates.
Ideally acid removed, the top of the battery should be cut off, plates removed, core cleaned out, the badly damaged plates are replaced, battery then out back together.
Years ago this is what was down.
Cut the battery open?
@@CarGroves they use to cut the top of the battery off. My friends father worked at a battery reconditioning company.
He had a 6 volt VW with a 12v battery, his dad added a 6 volt tap for the 6 volt system on the car. The starter, charger, and engine where set for 12 volts.
Adding erosion salt will clean the plates up, but will not rebuild the plated
when I lived in the Dominican Repbublic ages ago, this was what was done in every small town and the guy who did this was called, in English, "el Battery Doctor". This was how all the farmers and truckers survived. I ran construction jobs off them and they seemed to work.
they used to salvage plates from other batteries so that you had a united nations of plates in you battery.
I did this for a battery that died a week after I owned the truck , the battery fluid was a bit low I dumped a couple bottles of water in it and it was perfect . Holds charge 2 weeks latter cranks the duramax no issue
Nice.
Took me a minit to notice I thought you had another person also working on batteries lol 😆
I enjoyed your video as I know the expense of purchasing a new car battery. I liked your video, then I saw all your negative comments, but maybe do the test again, and actually show the recharged battery being started on the car, and run for a while and start as normal for some journeys over a period of time. Thanks for sharing
Thanks for watching Dale, second video coming soon
Hard to know where to start. Reusing old mixed dirty electrolyte, 'vinegar' to neutralise sulfuric acid??? Thinking that a 12v battery under 11v is somehow useful? It's dead, gone. What about the sulfate that is covering the cell plates? Glasses and flip flops?
Yes, I wear glasses and flip flops. What are you wearing right now...
Great stuff super video n info thx great !!!
