I did this method with an already dead 12 year old battery and 8 years later it still has enough juice to start my lawn tractor. It works like a charm. Thanks for this.
When I lived in Denver, there was a small company that did an actual rebuild. They'd cut the top off and put in new lead plates. Just like your video, several people told me that it would never work. The batteries I bought from the guy had the top cut off and epoxied back on. I don't know what he used. I had one of his batteries last over 12 years in a one ton Chevy van. Why would you listen to this video and complain that it would never work? Either do it or STFU. The man is just trying to help people. I for one will say thank you. Smiles.
... thanks for your honesty John, one thing to remember is the true condition of a battery is not in it's unloaded terminal voltage but in how it reacts under load. A good way to test is to take an old 12V incandescent lightbulb, a 60 watt seal-beam would work... measure the initial voltage then watch it drop over time. The batterie's amp-hour.. so many amperes for so many hours, it's simple math, it's the capacity at it's rated voltage is what counts for most. Once a flooded lead acid battery under load drops down to 11 volts, it's considered done... fully discharged. Something to remember.. yes a battery will recharge at 2 amps... but in the end they are being charged at 40 to 50 amps by an alternator, and the instantaneous discharge amperage can be 150 amps. Those are the end use realities John...
I watched a bunch of people trying various products. You are absolutely correct, only clean sulfuric acid will truly give you the chemical reaction required to produce the amperage required to start a vehicle. Thanks for doing the right thing. You’re a good man.
Thank you!!! I have been so confused.... so many videos telling me I need special chargers, videos don't do this... You must do this.. Etc... Etc... Etc... Thank you for explaining the truth and how to do this in a nice simple way!
Thanks John , I like your video , I like your talk and I like your walk , "no BS" straight to the point , I wish more people would do videos like yourself.
Thanks John. After reviewing some comments, I did find out that "hardware store" Sulfuric acid is fine. But then, someone elaborated about Epsom Salt being an acid replacement, in effect; explaining the reaction involved, and implying you could run with just that; no fresh acid. That was very interesting, and seemed like maybe even a better long term solution, because the remaining salt could continually donate more magnesium as time goes by. But of course, we want to know: What is the best route after done charging with the Salt? Leave it in, or replace with fresh Acid for service use?
Hi John, You say don't ever use baking soda to wash out a bat after you drain the old electrolyte ... because of the sediment collecting at the bottom of the cells. My suggestion would be not to try to use a strong alkaline mix ... not so much that you will see sediment. Do NOT saturate or even come close to saturated solution ... Also if you keep it warm the bicarbonate will not recrystallize/sediment ... maybe a heating pad under the bat will keep it good. After a few good rinses with a weaker solution then a few more with just distilled water then do the Epsom salt conditioning ... this should be enough to get a mild sulfated condition out of the way. If it's really sulfated then only reverse high voltage fast discharges are required to break up nasty sulfate bridges. This is usually for really old bats that have been abused to the hilt. I'm trying to recall my old chem classes about how Magnesium Sulfate can/would dissolve whatever the sulfate bridges form in a cell. I'm thinking copper sulfate bridges ? Since the residues one sees under the cell caps is blueish green ... copper sulfate. I know the chemistry is simple but it's been quite a while and I'm a musician not a chemist these days. What is the pH value of the Epsom salt solution you use ? If it's alkaline then baking soda will do the same thing in just a first initial cleaning. Just a weak solution ... water will do the rest ...just extra time and effort to get it nice and clean ... then the Epsom salt solution will do the rest. Next question ... you didn't specify how you mixed the new sulfuric acid electrolyte solution. I suppose it's hard to know what the volume of each cell is in order to calculate the acid water balance for the right balance in a calculation. The acid I have on hand says it's somewhere between 70 and 90 % pure ... really hard to know for sure. The really pure stuff is super expensive so I don't buy that stuff. So using that reference how would you mix it with distilled water ie. ratio ? I'm sure there is a specific gravity measurement but the only SG unit I have requires large amounts of solution to measure ... like 250 ml or more. I was thinking of those anti-freeze SG dealy's ... not sure if that would work with battery electrolyte. I remember waaay back that you could use one to test battery electrolyte concentration but I'm leaning to no ... also maybe a ppm meter might be used ? So Basically I am in the throes of reviving a bat that almost looks like it has a weak cell. Left on 2A charge for 2 days and it only got up to 11.68 VDC. Water levels were quite low when I checked so topped up and set to charge for 2 plus days. Only got to 11.68 VDC. ... gotta be a weak cell ... will do the indie cell test next. Would be helpful if you had mentioned in yer vid how you mixed the new sulfuric acid electrolyte for the right balance ? How much water to how much acid and @ what % strength ? You seem like a pretty stand up guy and I like that quality in a HU-man ... I'm very much into Tesla and all that entails. I am quite versed in EM theory and how it has been lets say ... attenuated in the text books. I have designed a new DC motor that when a mechanical load is put upon it, the power usage goes DOWN ! I have video evidence to support it. THIS is NOT supposed to happen !!! Today's motors use a lot more WATTS when the load is applied whether electrical or mechanical ... this is standard theory. I built a motor that defies that principal ... explain that to the math guys. You know what none of that stuff I just wrote is important ... I have a god damned battery to revive !!!
If u want correct acid proportion mix small amount in, test with hydrometer, if SG is too low add some more acid in, small amount to prevent over reaction, check SG again. Continue til SG gets high enough to show in the green region. Must have hydrometer to measure the concentration which should be 35% (65% water).
Funny stuff dude. I like how you came clean on the first video and I agree with your advice about just go and get another battery if you can afford one. You blew my mind when you let the cat out of the bag about 2 by 4's, lol...loving it!
Thanks, honest man. How about rinsing the battery sells with baking soda solution a few times before putting Epsom salt solution in the battery and then charging it would that be good, because I have heard the surface of the plates in the sells need to be cleaned by the baking soda solution.
thanks john for the info can we wash the battery out with spring water or rain water and than do the salt just to get the black stuff out of it first thanks again
Both acids & bases can be variably corrosive in degrees as cleaning agents & electrolytes, but on opposite sides of the PH scale where they react until stabilized in a more neutral or diluted position.
Sometimes the method does work have used household vinegar and emergencies to get a battery going. And then I went to the store and bought a newt eventually bought a new one 12:19
Get in touch with the size details of your traction battery box (Height, width and length), the voltage and some picture if you can and we will send out a no obligation quote.
So, do you need to put acid in or not? You aren't real clear. Do you have to trickle charge a bit before tipping out the original acid? Do you tip all the acid out? Will the Epsom salt mixture revive the battery after a trickle charge or not? Do you have to wait two years before putting new acid in or not? So much conflicting information on this topic. I did watch a video where some guy rinsed out the battery several times with baking soda solution. Guaranteed to work he said. It did in his video. I wondered what the Epsom salt would have to work with if the battery were really cleaned out. Oh well, I'll try something. My battery costs 500 dollars.
Awwwe...! C'mon brother, I like spam fried with bologna mayo and tomato.😂 Good vid my man, I appreciate your attitude towards the nay-sayers and this vlog even if I didn't let my battery sit for 3yrs it worked like a charm !!! TY
John, I'm surprised you haven't mentioned in either Pt.1 or Pt2 the most important electrical aspect of a battery. "CURRENT." Yes voltage is important but the real "proof in the pudding" as you call it is how much current that battery can produce when the proper "LOAD" is applied. When you take a car battery down to Walmart or Autozone, for example, to have them check to see if the battery is good what do they do? They use an electronic checker that puts a "resistive load" on the battery while monitoring the voltage and current. If the test battery can't supply the proper current then it's no good even if it initially displayed 10-12 volts unloaded. Please show your viewers the correct way to check a 12 volt battery. Put the proper load on it by installing in your truck and start the truck to prove your point. And, yes, for the record, I have tried your method on two different batteries. Both read the proper voltage until I tried to start the engine, ie, put the proper load on it, then the voltage dropped too low to do anything. I applaud you for correcting some misinformation in Pt2 but you still didn't test the current capacity by loading the battery.
@@youray95 He said he doesn't make $ off the 10% discounts you get from the codes he provided. And I think he also said "he doesn't do it for the $, but that doesn't mean he doesn't make ANY money form people viewing his videos. I'm not going to rewatch it to make sure I'm 100% correct, but I'm pretty sure he never claimed he never made $ from his RUclips videos. Either way, like you said, it's a great video, why not leave it at that...? But no, you basically comment saying great video, but you're a liar. Lol. That's one backwards ass compliment! Let me just say, great video, and thank you for teaching me something! And P.S... I hope you are making some $ off these videos, because imagine how much money you've saved your viewers! (Sorry, just couldn't read that comment and not call BS, lol)
Internal battery resistance reduces the CCA capacity of the battery. Caused by Sulfation. Epsom salt helps to desulfate but must do cycling/charge-discharge of battery to bring back the CCA level to the rated spec. CCA is shown on the battery label. Cold Cranking Amps design of the battery. He does not discuss these requirements for reconditioning the battery.
Thanks. Neat trick about checking cells. I think the "Don't set batteries on cement" goes back to the days when they had bakelite cases. I sat through about 5 minutes of the ez battery commercial before the smoke being blown up my ass started coming out of my ears and I went to youtube. I had watched your first vid before but hadn't tried it yet. I got a couple batteries laying around I'll try it on.
You're right, the proof is in the pudding. Well explained also. But one inconsistency: first video you said you can do this 4 times, this video you said it's a one time thing. Can you clarify?
I got my free multimeter from Harbor Freight. They also have a specialized battery tester showing cold crank amps, voltage, internal resistance, state of charge, state of health. Goes for about $60 but well worth it.
2007 battery says it is good to 2012, out of a Honda. 4 volts lol, Yeah, I bet the way the sides are swollen on the ends is not a good sign either. Honda wants $350. Auto parts stores $150 - $200. I had a 84 mazda p/u the battery went bad so I took the one out of my riding mower an ran it for over a year with no problems. Damn this batter looks a lot like a riding mower battery. Hmmm , what do you think ?
Did I miss your recommended set time for the Epson salt/distilled water to remain in and clean the battery? I’m sure it’s not three years on the ground. How long from water fill to dump empty? I’m a little slow on the recharge. LOL thanks for your response.good site
I'm sure that you realize by now that you do not remove the solution - it reacts with the acid and the gunk on the lead plates to make more acid apparently. I think that you can find out what the reaction is by googling Epson salts with sulfuric acid reaction. My guess is that the sulfate on the lead plates is destroyed as magnesium is released leaving sulfate ions to become more sulfuric acid which increases the strength of the acid so that it creates more reaction until the Epson salts are used up. The recharge is done at 1 to 2 amps for a long time. Others claim that you can forget the Epson salts and just trickle charge with rest periods for a very long time - like slow charge 24 hrs rest 2 hours slow charge 24 hours for a total of 4 to 5 days of charging. Then switch to a regular fast charger to top it off after the last rest. When finished the battery should have a voltage over 13 vdc but it will slowly drift down to 12.6 vdc within an hour or two. Then it will slowly drop a few tenths of a volt per day until about 10 to 11 vdc when you really should charge it again. Better yet leave a booster charger on it - one that will monitor the voltage for less than 13 vdc charges it to 13.5 vdc then quits charging until the voltage drops again, etc. The claim is that the slow charging will remove the sulfate that is on the plates and that the Epson salts really do nothing - the slow charge did it.
I could not resist - a cell of a lead acid battery at no load shows 2.1 to 2.2 vdc, which is 12.6 to 13.2 vdc for six cells. When loaded with a reasonable load like in an automobile not cranking, the voltage will be 12 vdc and a good battery will hold that voltage - that is where 12 volt battery comes from. The cranking voltage is more important and it will drop below 12 volts if the starter draws too many amps. In the winter time, they do, so that is spec'ed as cold cranking amps at a specified temperature. A 2x4 piece of lumber started out cut at 2" x 4", but then they planed it down to about 1.5" x 3.5" hence a 2x4. But I'm sure that you knew this, why not say so. Another thing; yes it is ok to place the battery on a piece of concrete, but realize that there is acid in it and the battery seems to always find a way to get enough acid on the concrete to disfigure the surface enough to wish you had not - and it doesn't take 3 years either, but a few months even with a new battery if not properly cleaned after being charged. I am not certain of the processes involved, but I know it happens because I have had it happen even though I generally put some cardboard or something under the battery for storage on the cement floor. When I have not done so, the battery let its presence be known.
I wish you shown the type of charger you used! The first video you said 2amp trickle charge, this video you talked about it getting stronger then , floating? I don't know if my charger does that, or even know what that means! Wish you shown your charger and explained that a bit this time around,, but good video, thanks!
Try Google dude, lol, there's plenty of info on that available. It's not like you have to depend solely on him to explain everything. If he did, he'd eventually be doing "Part 36" with a cane and a long beard, like ok, I forgot to explain how the lead plates are made and the brand of epson salt I used. Lol Take some initiative man!
Its one thing to "believe". And I do think its worth a go, but you have done no tests other than a voltage test, which is too low. After disconnecting immediately from charging for several hours, I'd expect it to see over 13 volts, and even if left to settle for some time, I'd want to see 12.6v or more. You could do a load test, or better yet, connect to your truck in the background and show it turning over. Science is about results.
Great videos! My digital battery charger has a recondition mode that takes up to 24 hours (according to manual). Is this the same as the slow charge you talk about after prolonging the battery? I believe it's a desolate mode.
I had a new Interstate go bad in 6 weeks (1 dead cell), they replaced it, and gave me an upgrade, 2 months later it's dead, the Parasitic amp draw test showed my van pulled only .036 milliamps, the batteries were made in Mexico, go figure
I know this is an old video. And I hope you read this. In your first video you said not to reconditioned if less then 9v. Is there anyway to recover a battery less then 9 volts? Is there a chance batteries less then 9v will come back? I ask because one battery is $100, but 10 batteries is $1000.
@@Pioneerjohnmilandred well I picked up the acid and Epson today. Will try. If it works I plan to drain and acid it again. I have 8 batteries I need to do. Btw I figured cost and if it does it on two tries, $7 for acid and $2 for epson and water, per battery for a total of $9 to restore $120 battery is well worth it. At this point I will try the epson many times if thats what is needed. With all concidered, even if it takes 25 times its STILL better then half the price of a new battery. Bad news is they only had enough acid for 2 batteries. But if the Epson salt works I'll get more acid, another $25 for acid will cover all them. ( different store in a different city 100 miles away has acid in 5 gallons container) yeah I was surprised at the price though it would be more. Will be doing more batteries also, now that I know. Now I wish I knew how to get unwanted deep cells battieries.
@@realdevbro447 yes and it didn't work for me. BUT. 1st I believe the plates burned up. So no matter what nothing short of rebuild will work. NOW. I will say, in some it did improve the volts. Just not enough. Again back to the plates. By this I mean. A couple battaries were like 4ish volts. And it made them 6ish. In all the battaries I have dead cells. This is why I determined it fried the plates. And as a FYI. I know there is an arguement about this. By from what I learned from experience. Battaries will work on Epson salt. However the charge slowly drains. I have yet to do it. But I plan to have the batteries rebuilt. I looked into that and it seems reasonable.
YES! There are several videos that explain how to revive a drill battery pack. Your weed eater will have a battery just like a drill. Basically once the battery drains too low the charges "sees" it as bad, you have to use another charged battery to raise the voltage of the "dead" battery. It works, I have done it with Dewalt and Milwaukee batteries.
I have done this by taking the batteries apart and finding which cells are dead. Remove them and insert cells from another old battery of the same kind that are still good. You can make it last a little longer, but it is probably a waste of time since the activity of soldering on them, etc., and the fact that they are already old is going to be a problem shortly. Best thing to do is to buy a new unit - the 20 volt lithium ion (or higher voltage) battery with charger and one extra battery. Don't run the lithium until it gets hot - run it for just a certain length of time (you will discover how long they will run and swap them out several minutes before you think the battery will quit.) The batteries will last a lot longer if you don't let them get too hot so most power tools have protection for that, but exceed it if you can by shutting down periodically rather than running continuously or by feeling the battery. If the battery starts to get hot, let it cool off. Or you might switch to another charged battery and continue while the first one charges and then cools off again. The lithium ion batteries are much better than NMH or NiCad batteries and will output as much as either of them without the slow drain that the others exhibit (and which is a pita) while not being used. Earlier lithiums were less reliable but the lithium ions are great. Most of the old power tools that used NiCad or NMH batteries were 12 - 18 volt but the motors inside were rated at 20 vdc or higher. If you wanted to, the old tool could be reworked to operate with lithium ion batteries if some way to connect the battery can be devised. Check the motor in the tool for its rating, purchase two lithium ion batteries and charger (or use one from another tool that you already own) with a lower or equal voltage rating, devise a means to attach the battery and you can convert your tool to lithium. The battery has all of the protections within it so don't worry about the other connections other than + and -. Of course you have to quit before the battery gets hot anyway, but this should operate the tool like a champ. However, purchasing a new tool for lithium usually includes at least one battery and a charger plus a discount on the second battery so that is the way to go rather than modifying an old tool - plus you get a brand new tool.
Load test before and after. Charging high rates????? ark welder or jump starter. Volt meter tells nothing without a load test,. Want 200 AMps at 10volts.
Go for it, Man! The reason why batteries cost about $30 $30 years ago and over a hundred now, is that they know you can't run your car without it. They could charge $500 and people would still have to buy them. As for me, I am going to be reconditioning more often, as long as it does'nt leak.
Technically you don't need a battery is a lot of cars. On my truck a battery is only to start it. The alt runs the truck after that. So as long as you have something to start your truck then you're good to go
Ok, I'm trying it with an old marine battery. So far I have killed it with baking soda, (suggested from another video not yours)did a few rinses with Epsom salt and distilled water with overnight charging at 2amps, this is the fourth day of rinsing and charging. I saved the old electrolyte ,it settled out over night with all of the muck on the bottom. I then poured off the clear electrolyte and re-used it with Epsom salt , right away voltage jumped up .I put on my charger and the resistance was at 2amps as compared to an original very high resistance. I only plan on using this battery on LED solar lighting around the yard or, for camping, not in a vehicle. Great video! If you are really into this , I found this during a search on this very subject using different sulfates. patents.google.com/patent/US5945236A/en Update! Day 6 I am surprised this battery came back to life, I put this in my old Ford Galaxie and it actually cranked the V8 engine over , however it still does not have the full cranking amps. I will let it sit a couple of days and try it again to see if it holds a charge. How long it will last , who knows?
Your method actually seems the best method that I have come across. I also am hoping to create a Solar battery bank for off grid charging of my phev Honda clarity
And it's concentration should be what? Also, can I bypass all that Epsom salt/water solution and simply replace sold acid with new one? Is that gonna work better as far as battery holding charge?
You proved nothing useful. I've seen lots of batteries gain voltage through different methods and have no useful amperage. Put that battery in a car and start it, that'll prove something.
Harbor Freight gives the OHM meters away for FREE with a coupon...ask a neighbor for a battery charger. Theres always at least one in your neighborhood.
All Americans are on a budget unless you're over at your house and then I start telling you how much everything cost you know the TV the couch the lamp know one damn good and well s*** ain't that much

So, do you need to put acid in or not? You aren't real clear. Do you have to trickle charge a bit before tipping out the original acid? Do you tip all the acid out? Will the Epsom salt mixture revive the battery after a trickle charge or not? Do you have to wait two years before putting new acid in or not?
So much conflicting information on this topic.
I did watch a video where some guy rinsed out the battery several times with baking soda solution. Guaranteed to work he said. It did in his video. I wondered what the Epsom salt would have to work with if the battery were really cleaned out.
Oh well, I'll try something.
My battery costs 500 dollars.
Eventually you can retire the battery as a 12v lighting circuit with 100w solar panel and charge controller.
I LIKE THE WAY THIS GUY IS YOU STUFF IS GREAT YOU DONT LIE
what can I do if I listen to those people and put the baking soda in the battery. what can i do to get the stuff out
Thanx very much , very good info that was well presented that I am going to have to try.
Will that start a car at 12.2 volt though? And also once in the car will it hold a high enough voltage to use even on a cold morning for example?
Acid or Epsom salts what do you use the first time clean acid or Epsom salts
Awwwe...!
C'mon brother, I like spam fried with bologna mayo and tomato.😂
Good vid my man, I appreciate your attitude towards the nay-sayers and this vlog even if I didn't let my battery sit for 3yrs it worked like a charm !!!
TY
have you ever try to solar charge it ????
Can you use the old battery acid that you took out if you strain it through a cloth? If not where can you buy a new battery acid from?
auto parts store
Caustic soda is alkaline, just like the baking soda you said to never use; both will neutralize an acid
John, I'm surprised you haven't mentioned in either Pt.1 or Pt2 the most important electrical aspect of a battery. "CURRENT." Yes voltage is important but the real "proof in the pudding" as you call it is how much current that battery can produce when the proper "LOAD" is applied. When you take a car battery down to Walmart or Autozone, for example, to have them check to see if the battery is good what do they do? They use an electronic checker that puts a "resistive load" on the battery while monitoring the voltage and current. If the test battery can't supply the proper current then it's no good even if it initially displayed 10-12 volts unloaded. Please show your viewers the correct way to check a 12 volt battery. Put the proper load on it by installing in your truck and start the truck to prove your point. And, yes, for the record, I have tried your method on two different batteries. Both read the proper voltage until I tried to start the engine, ie, put the proper load on it, then the voltage dropped too low to do anything. I applaud you for correcting some misinformation in Pt2 but you still didn't test the current capacity by loading the battery.

Internal battery resistance reduces the CCA capacity of the battery. Caused by Sulfation. Epsom salt helps to desulfate but must do cycling/charge-discharge of battery to bring back the CCA level to the rated spec. CCA is shown on the battery label. Cold Cranking Amps design of the battery. He does not discuss these requirements for reconditioning the battery.
I agree he did not test the battery
How much acid do you put in each cell?
Thank you, and I appreciate you, and may peace be unto you and to your family and all that you have, Shalom.
Thanks. Neat trick about checking cells. I think the "Don't set batteries on cement" goes back to the days when they had bakelite cases. I sat through about 5 minutes of the ez battery commercial before the smoke being blown up my ass started coming out of my ears and I went to youtube. I had watched your first vid before but hadn't tried it yet. I got a couple batteries laying around I'll try it on.
Can you do this to a 2 year old battery that still works to prolonged it life ?
The only thing an old battery needs is probably topped up because they dry out...the main reason they get weak or die.
Hello .
So what I should do ???
I drain the battery 100%
And I cleaned with baking soda.
Still no charge...
You're right, the proof is in the pudding. Well explained also. But one inconsistency: first video you said you can do this 4 times, this video you said it's a one time thing. Can you clarify?
Just wondering if you have done a load test pon? Or could show it starting your vehicle
harbor freight tools gives the meters away with a purchase pretty often as well.
I got my free multimeter from Harbor Freight. They also have a specialized battery tester showing cold crank amps, voltage, internal resistance, state of charge, state of health. Goes for about $60 but well worth it.
How does it hold up to a load tester how much does it drop in volts. Good vi deo
Can one wash battery cells with tap water
Where do you buy battery acid
What is the salt for again the one that you mix first in the first video?
2007 battery says it is good to 2012, out of a Honda. 4 volts lol, Yeah, I bet the way the sides are swollen on the ends is not a good sign either. Honda wants $350. Auto parts stores $150 - $200. I had a 84 mazda p/u the battery went bad so I took the one out of my riding mower an ran it for over a year with no problems. Damn this batter looks a lot like a riding mower battery. Hmmm , what do you think ?
Did I miss your recommended set time for the Epson salt/distilled water to remain in and clean the battery? I’m sure it’s not three years on the ground. How long from water fill to dump empty? I’m a little slow on the recharge. LOL thanks for your response.good site
I'm sure that you realize by now that you do not remove the solution - it reacts with the acid and the gunk on the lead plates to make more acid apparently. I think that you can find out what the reaction is by googling Epson salts with sulfuric acid reaction. My guess is that the sulfate on the lead plates is destroyed as magnesium is released leaving sulfate ions to become more sulfuric acid which increases the strength of the acid so that it creates more reaction until the Epson salts are used up.
The recharge is done at 1 to 2 amps for a long time. Others claim that you can forget the Epson salts and just trickle charge with rest periods for a very long time - like slow charge 24 hrs rest 2 hours slow charge 24 hours for a total of 4 to 5 days of charging. Then switch to a regular fast charger to top it off after the last rest. When finished the battery should have a voltage over 13 vdc but it will slowly drift down to 12.6 vdc within an hour or two. Then it will slowly drop a few tenths of a volt per day until about 10 to 11 vdc when you really should charge it again. Better yet leave a booster charger on it - one that will monitor the voltage for less than 13 vdc charges it to 13.5 vdc then quits charging until the voltage drops again, etc. The claim is that the slow charging will remove the sulfate that is on the plates and that the Epson salts really do nothing - the slow charge did it.
You did great!
I could not resist - a cell of a lead acid battery at no load shows 2.1 to 2.2 vdc, which is 12.6 to 13.2 vdc for six cells. When loaded with a reasonable load like in an automobile not cranking, the voltage will be 12 vdc and a good battery will hold that voltage - that is where 12 volt battery comes from. The cranking voltage is more important and it will drop below 12 volts if the starter draws too many amps. In the winter time, they do, so that is spec'ed as cold cranking amps at a specified temperature.
A 2x4 piece of lumber started out cut at 2" x 4", but then they planed it down to about 1.5" x 3.5" hence a 2x4. But I'm sure that you knew this, why not say so.
Another thing; yes it is ok to place the battery on a piece of concrete, but realize that there is acid in it and the battery seems to always find a way to get enough acid on the concrete to disfigure the surface enough to wish you had not - and it doesn't take 3 years either, but a few months even with a new battery if not properly cleaned after being charged. I am not certain of the processes involved, but I know it happens because I have had it happen even though I generally put some cardboard or something under the battery for storage on the cement floor. When I have not done so, the battery let its presence be known.
Kickass follow up! Thanks man!
Salute......Salute..... Salute.... Good job...... Keep it up. M subscribing your channel.
hi John. hope you are fine. its a nice video. Here in germany its hard to find Epsom salt. is it also called Bathsalt?
What happens if some of your cells are short
Can you send me a 1x1 procedure. Thank you
Can you run more videos with differents types of batteries like N 200 etc?
I wish you shown the type of charger you used! The first video you said 2amp trickle charge, this video you talked about it getting stronger then , floating? I don't know if my charger does that, or even know what that means! Wish you shown your charger and explained that a bit this time around,, but good video, thanks!
Try Google dude, lol, there's plenty of info on that available. It's not like you have to depend solely on him to explain everything. If he did, he'd eventually be doing "Part 36" with a cane and a long beard, like ok, I forgot to explain how the lead plates are made and the brand of epson salt I used. Lol
Take some initiative man!
We got the Jamie from mythbusters look going on
Thank you for your time
Its one thing to "believe". And I do think its worth a go, but you have done no tests other than a voltage test, which is too low. After disconnecting immediately from charging for several hours, I'd expect it to see over 13 volts, and even if left to settle for some time, I'd want to see 12.6v or more. You could do a load test, or better yet, connect to your truck in the background and show it turning over. Science is about results.
Good video, good info! Thank you very much for taking your time to make this
what's the name of the acid and where can you buy it? By the way, thanks for info!!!
Great,informative vid. Thank You. I will try this on my motorcycle battery and let you know how it goes.
dito on all the good comments
God bless you. You did great.
How long will a battery last when you refurbish it
Til the lead in the plates gets too thin.
Thank you …. like your style .
Great videos! My digital battery charger has a recondition mode that takes up to 24 hours (according to manual). Is this the same as the slow charge you talk about after prolonging the battery? I believe it's a desolate mode.
I had a new Interstate go bad in 6 weeks (1 dead cell), they replaced it, and gave me an upgrade, 2 months later it's dead, the Parasitic amp draw test showed my van pulled only .036 milliamps, the batteries were made in Mexico, go figure
I know this is an old video. And I hope you read this.
In your first video you said not to reconditioned if less then 9v.
Is there anyway to recover a battery less then 9 volts?
Is there a chance batteries less then 9v will come back?
I ask because one battery is $100, but 10 batteries is $1000.
@@Pioneerjohnmilandred well I picked up the acid and Epson today. Will try. If it works I plan to drain and acid it again. I have 8 batteries I need to do.
Btw I figured cost and if it does it on two tries, $7 for acid and $2 for epson and water, per battery for a total of $9 to restore $120 battery is well worth it. At this point I will try the epson many times if thats what is needed. With all concidered, even if it takes 25 times its STILL better then half the price of a new battery. Bad news is they only had enough acid for 2 batteries. But if the Epson salt works I'll get more acid, another $25 for acid will cover all them. ( different store in a different city 100 miles away has acid in 5 gallons container) yeah I was surprised at the price though it would be more. Will be doing more batteries also, now that I know. Now I wish I knew how to get unwanted deep cells battieries.
@@pychohobo1832 did you try it?
@@realdevbro447 yes and it didn't work for me.
BUT.
1st I believe the plates burned up. So no matter what nothing short of rebuild will work.
NOW.
I will say, in some it did improve the volts. Just not enough. Again back to the plates. By this I mean. A couple battaries were like 4ish volts. And it made them 6ish.
In all the battaries I have dead cells. This is why I determined it fried the plates.
And as a FYI. I know there is an arguement about this. By from what I learned from experience. Battaries will work on Epson salt. However the charge slowly drains.
I have yet to do it. But I plan to have the batteries rebuilt. I looked into that and it seems reasonable.
@@pychohobo1832 Ty for the reply.
that was actually two words lol i still like the video very informative thanks
If a cell is dead then what I do
Get a new battery
Can this work on a optima battery
Gel ? No
Hey bro ,is it true even an 4yrs old battery can make it that way?
Where do you get fresh battery acid from?
@@Pioneerjohnmilandred When u buy this acid what is it called ? Just want to be sure of what im buying.
hahaha at 12:05 (No offence John, but technically that's two words!) 😂
going to try it ...my aspirin and desteeled water was no go ...guess this is my last dich thanks for the tips
I have like 10 batteries and none of them have removable caps. Most every battery I have seen over the years appear to be sealed.
Remove the sticker on the battery and you should find the caps.
what about an optma 12 volt battery. ???
i like your video id like to see your battery on a load tester.
Keep up the good work my man
I like your style man.

i have bad 18v weed eater battery can a person make it work.
Ben Brewer no its probably lithium batt
YES! There are several videos that explain how to revive a drill battery pack. Your weed eater will have a battery just like a drill. Basically once the battery drains too low the charges "sees" it as bad, you have to use another charged battery to raise the voltage of the "dead" battery. It works, I have done it with Dewalt and Milwaukee batteries.
I have done this by taking the batteries apart and finding which cells are dead. Remove them and insert cells from another old battery of the same kind that are still good. You can make it last a little longer, but it is probably a waste of time since the activity of soldering on them, etc., and the fact that they are already old is going to be a problem shortly.
Best thing to do is to buy a new unit - the 20 volt lithium ion (or higher voltage) battery with charger and one extra battery. Don't run the lithium until it gets hot - run it for just a certain length of time (you will discover how long they will run and swap them out several minutes before you think the battery will quit.) The batteries will last a lot longer if you don't let them get too hot so most power tools have protection for that, but exceed it if you can by shutting down periodically rather than running continuously or by feeling the battery. If the battery starts to get hot, let it cool off. Or you might switch to another charged battery and continue while the first one charges and then cools off again.
The lithium ion batteries are much better than NMH or NiCad batteries and will output as much as either of them without the slow drain that the others exhibit (and which is a pita) while not being used. Earlier lithiums were less reliable but the lithium ions are great.
Most of the old power tools that used NiCad or NMH batteries were 12 - 18 volt but the motors inside were rated at 20 vdc or higher. If you wanted to, the old tool could be reworked to operate with lithium ion batteries if some way to connect the battery can be devised. Check the motor in the tool for its rating, purchase two lithium ion batteries and charger (or use one from another tool that you already own) with a lower or equal voltage rating, devise a means to attach the battery and you can convert your tool to lithium. The battery has all of the protections within it so don't worry about the other connections other than + and -. Of course you have to quit before the battery gets hot anyway, but this should operate the tool like a champ.
However, purchasing a new tool for lithium usually includes at least one battery and a charger plus a discount on the second battery so that is the way to go rather than modifying an old tool - plus you get a brand new tool.
when the chips are down..i want this dude not far down the hollow..
Load test before and after. Charging high rates????? ark welder or jump starter. Volt meter tells nothing without a load test,. Want 200 AMps at 10volts.
He didn't say, Suck It. He said, SOCKET!!! That is one word.
hahaha, my bad... I called him out on his use of two words!
Thanks for the info and the video brother :)
Go for it, Man! The reason why batteries cost about $30 $30 years ago and over a hundred now, is that they know you can't run your car without it. They could charge $500 and people would still have to buy them. As for me, I am going to be reconditioning more often, as long as it does'nt leak.
Technically you don't need a battery is a lot of cars. On my truck a battery is only to start it. The alt runs the truck after that. So as long as you have something to start your truck then you're good to go
Awesome video,Keep it up!
good job
Ok, I'm trying it with an old marine battery. So far I have killed it with baking soda, (suggested from another video not yours)did a few rinses with Epsom salt and distilled water with overnight charging at 2amps, this is the fourth day of rinsing and charging. I saved the old electrolyte ,it settled out over night with all of the muck on the bottom. I then poured off the clear electrolyte and re-used it with Epsom salt , right away voltage jumped up .I put on my charger and the resistance was at 2amps as compared to an original very high resistance. I only plan on using this battery on LED solar lighting around the yard or, for camping, not in a vehicle. Great video!
If you are really into this , I found this during a search on this very subject using different sulfates.

Update! Day 6
I am surprised this battery came back to life, I put this in my old Ford Galaxie and it actually cranked the V8 engine over , however it still does not have the full cranking amps. I will let it sit a couple of days and try it again to see if it holds a charge.
How long it will last , who knows?
Your method actually seems the best method that I have come across. I also am hoping to create a Solar battery bank for off grid charging of my phev Honda clarity
I did the same mistake w baking soda, what is your rinse process?
ob. how much acid
WHAT KIND OR TYPE OF ACID DO YOU PUT IN THERE?
And it's concentration should be what?
Also, can I bypass all that Epsom salt/water solution and simply replace sold acid with new one?
Is that gonna work better as far as battery holding charge?
You proved nothing useful. I've seen lots of batteries gain voltage through different methods and have no useful amperage. Put that battery in a car and start it, that'll prove something.
