Turn a dead non-spillable sealed lead acid battery in to a good semi-spillable lead acid battery by simple methods. No Epsom Salt or Alum Rock is used in this video!
I have watched at least 50 videos, and this one was perfect, explains everything clearly, shows everything and how to do, no annoying background music or distractions, no tricks, just clear, precise, well layed out explanation. Thank you.
Agree great job started watching you on other videos over a year ago (I recognized the voice) only reason I watched as your ebike vids I love the builds, mods and explanations as I was learning back then! Thank you!
I have tried ALL the methods to revive lead acid batteries over the last 55 years! Some of them helped a little most of them turned the battery into junk! I tried this method on my 3 year old motorcycle battery that lost two cells??? don't know why?? I always charge the battery on a tender for a week when removed in the fall and recharge again in the spring for a week prior to going back into service. I have yard equipment batteries that are 12-15 years old and continue to work like new! When I removed the "do not remove" cap string on the battery, I noticed it was bone dry! I took this procedure 1 step further and added batt acid to just cover the plates. The cells took between 20-30 cc's of acid each!! I used a 2 Amp charger, the start voltage was 10.50 V it stayed there for 3-4 hrs. when I had looked at the meter again the voltage was now 11.75 V it was a steady reading. 4-5 hrs later to my pleasant surprise it showed 13.05 Volts! Over night next morning I had 15.88V. I will tenter charge for a week and check the open ckt voltage after 24 hrs. $11.00 for acid to save a $150.00 battery! Thanks for sharing something that actually WORKS!!
Video recording was good, non of that stupid moving camera everywhere. Explanation was good, content was great. You actually did a capacity test and a load test. Great video. I gave you a thumbs up
Kudos for the Video! Forgive me for the intrusion, I am interested in your opinion. Have you thought about - Lammywalness Trendy Trade Guide (erm, check it on google should be there)? It is an awesome exclusive product for learning how to recondition batteries at home without the headache. Ive heard some incredible things about it and my close friend Aubrey after many years got astronomical results with it.
There are several components to doing a pro job. One resource I found that succeeds in merging these is the Jons Mender Guide (google it if you're interested) definately the most useful info i've seen. look at this amazing website.
What a great video. This should win an award and RUclips creators should reference it as exactly how to convey information effectively. Thanks and good job.
interesting points ,if anyone else is searching for how to recondition a lead acid battery try Jadonite Renovate Battery Buddy (do a search on google ) ? Ive heard some great things about it and my buddy got amazing success with it.
Increasing the sulfuric acid concentration is detrimental to the performance of the battery, because more will remain as a precipitate and eventually crystallize. His gains probably could have been achived with just distilled water, but hey, that's ONE piece of content that doesn't exist anywhere on RUclips, maybe I should make it...but lead sulfate is nasty stuff.
A lot of people think battery reconditioning is hard however I think I know it's incredibly simple. I have done it hundreds of time before, in fact it's what I do for a living [Check Details Here==> t.co/uUSuy6Yk5g ]. Anybody can recondition batteries, you just need to know the techniques.?
The more we all understand the hazards of reconditioning a battery, the safer we can all be when it comes to maintaining your battery. It just doesn’t make sense to blindly trust that tow truck mechanic trying to make $500 on a battery that just needs to be reconditioned. Did you make your video?
Hi, When I was gainfully employed, I maintained emergency services radio communication systems in the Highlands of Scotland. Some remote installations employed 12 and 24v dc solar/wind systems... Here are some tips I learnt the hard way! (when your up a gum tree without a paddle) Most service techs carried a variable 24 volt 10amp bench power supply in their vehicles... When we found a dud 12 v battery that would not charge (open circuit)we would dismantled it as shown in the video... With a multimeter connected to the neg terminal.. the positive meter terminal was connected to a thin screwdriver ..the screwdriver was pushed gently into each hole to touching the cell plates, that should measure around 2volts then the next hole 4 volts and so on... increasing by approx 2 volts each time eventually you will find an open circuit cell (probably dry) top up with distilled water and let it soak for an hour ...Now replace the multi meter with the bench power supply and carry out the same process watching the current meter and adjusting the voltage to find the faulty cell causing the open circuit...Eventually current will flow between the positive and negative terminals...Now connect the variable power supply with a car headlamp bulb in series to limit the current ...Now crank it up to 24volts whilst watching the current meter gradually reducing the voltage to keep the current at around 2amps...Now charge the entire battery at 13.8 volts for a few hours (after topping up all the cells with distilled water) ... Finally replace the rubber caps and cover with a strip of gaffer tape... At the next planned visit we would normally exchange the battery.. PS always wear safety glasses when doing this work!
🤩nice final drive 👍for 2 weeks I regenerate 4 gel batteries 12 v/20 ah with the addition of distilled water only, with a desulfator prototype made by me,
Caution, that is the best method, however, it does not work the vast majority of times; After 40 years as a mechanic i tried everything on batteries; when they are sulfated they are JUNK; ONE cell dies,the whole set of 6 is junk,and it's a shame that the cells are not replaceable one by one, like with the lifepo4s.
You have done great in this video.Please do a video on how to setup a battery reconditioning business:advice on the right tools and required materials necessary for the business
here's several tips for battery repairing do not attempt to do this until you know what you are doing - the acid can burn you check the voltage first - there may be a kaput cell which would waste your time. Check the battery fluid. Try to fully charge the battery. (I read about these and more from Jons Mender Guide site )

M Medina I watched a video that said if you drink tiny amounts of diluted battery acid then you can charge your car while driving it because your fingers will transmit micro electricity through the wheel is that true
It worked! I'd had all but given up on an old SLA.....but following these steps brought it back to life. I added more electrolyte as it charged - the amps went from 0.00 to 0.01 ......and the next morning 0.13.....and before I knew it, the thing was holding 12v. Thanks
Thank you. Chemistry and circuit diagrams. Explains it to intelligent humans so we can make INFORMED decisions. Much better than a numpty in a garage guessing what he's doing.
When you are finished. Build and use the Bedini "Energizer" to maintain the batteries for years as Sulfate is removed by Pulse charging them via back EMF. Thank you for sharing VUAECO. May you be blessed.
I am a Retired Avionics Tech. I forgot more than I learned about Electronics these days. But seriously you have expertly explained the method to keep batteries going and going. You expertly put the correct information that is needed. Now if I can ONLY figure out how to revive an AGM Lead Battery now, LOL The many fires and being not good for Cold Climates without a heat source for them, that the Lithium's are famous for, has led me back to Lead, LOL
Great video. The chemistry explanation helps with understanding why simply adding distilled water can't rejuvenate a dried out battery that won't take any charge. I loved the tests at the end too!
The real issue is if the battery plates are sulfated or not. If the plates are not sulfated adding distilled water will give you a usable battery. De sulfating with a welder is a little dangerous if you don't realize that the gas coming out of a sulfated battery is not so bad "UNTIL" it starts a rolling boil and realize that the fumes now smell like rotten eggs and burn your eye's. The chemical reaction takes place changing the liquid inside the battery. Remember too that the pre sulfuric acid phase is Hydrogen and Oxygen which is not dangerous BUT for the fact that it is highly explosive if ignited at the concentration close to the battery body. A fan and open area will avoid any issues there.
We used to always charge our dump truck batteries outdoors with a fan blowing away from us and obviously the caps popped off. You never want the batteries, boiling and building up pressure from what I understand. Would love to see a list of all of this guys. Tools and supplies for conditioning has batteries. Still have not found a better educational RUclips video.
There are many components to fixing a car battery. One place I found that succeeds in merging these is the Jons mender guide (check it out on google) without a doubt the most useful course that I have ever heard of. Check out this amazing site.
Ya i agree with what they all said, very well done video. clear, precise instructions and you actually tested them after!!! Love it! Thanks for putting out such useful content for others to see.

Man you're awesome. I wish I had people like you around when i was younger. Now I'm 41 crash coursing battery tech. Batteries have always interested me. Supposedly in the future we are supposed to go black. No wifi no cell. No radio. No electric. So a person should definitely learn about batteries
There are actually few older videos as well as written guides. I've been doing this few years ago, sadly it doesn't fully revive dead battery and it will most likely die in few months. Capacity is also significantly reduced.
I\'m not sure but ,if anyone else wants to uncover how to recondition old batteries at home try t.co/uUSuy6Yk5g ? Ive heard some decent things about it and my mate got excellent results with it.
@@marquishainse5985 It a very Expensive price of 47 Dollars . it big amount cost. give me ida's. My email theengineringzone13@gmail.com ok Thanks. Nasir
The chemistry of how battery functions and deteriates was very well explained. Very helpful. Not so sure if battery desulfation process will be successful. A battery recoverable capability varies.
This was very helpful. Thank you for putting this on youtube. I have watched a bunch of videos on rejuvenating batteries. Yours was one of the most useful And helpful. I appreciate it. Thank you!
I brought up a dead Costco interstate with a 20watt solar panel and the exact same solar charge controller used in this video connected directly to the battery. I did add some distilled water. The solar charge controller will charge the battery at exactly .1 volt (1/10 of a volt) higher than whatever charge is on the battery. I think it is better than using another battery to parallel charge. It did take over a week, but this 5 yr old battery was completey restored to something a only little less than new operating power. I also had a brand new non-Interstate car battery and it would only rate between 11.9 V- 12.2V depending how recently I drove the car. When brand new I treated that particular brand new battery to some extra electrolyte in the form of sodium sulfate salt (Na2SO4) which is supposed to quadraple battery life. This didn't make a difference in the performance of the battery with normal car alternator charging. Info from Turquoise Energy did tell me to cycle the battery, but lead acid are not deep cycle and I just relied on the alternator. (Although this sodium sulfate salt chemical is what they use on deep cycle lead acid). It is only when I left a 25w solar panel/$12 charge controller on the battery for a month or more, did I experience sustained higher than average charge levels. In fact, after that, when the car sat for 2 month undriven and uncharged in any way during covid and rain with the battery disconnected, the battery still held 12.5 volts: better than new!! Sulfation is reversible, corrosion is not. Extra electrolyte might help but, it is the trickle charge at the right voltage that makes the big difference. (It is not advised to put sodium sulfate salt into an old battery as it might cause bits to dislodge and short out the battery)
Great comment. Someone else had a similar story with a battery that refused to revive after mag. sulfate and pulse charging sessions. Spent a year on light shed led duty on a solar trickle charger and came back very close to new. Seems like desulfation can work but it can take a lot longer than people expecting to have an overnight fix for their ride's battery.
I can confirm that this worked for me on my grandsons TTR110 bike battery. It was totally dead for a long time, would not take a charge. After doing this it changed and starts the bike just fine. Thanks for making this great video.
I ALWAYS ADDED WATER TO MY SCOUTER BATTERY TO REVIVE IT A BIT. BUT WHAT I REALLY LIKED IN THIS THIS VIDEO IS THE 30% , 2 ML H2SO4 TO THE WATER. NEVER THOUGHT IT WOULD NEED ACID. THANKS FOR THE TIP. SUBSCRIBED.
This is one of the best videos on restoring a battery I have seen. I play around with restoring battery's because I have so many thing that use them. I,m going to try this. I subscribed to your channel, & thank you.
Excellent video. Very valuable information. I tried this process on almost a dead battery. I had to use trickle charger instead a big battery in parallel. It took about a week for first full charge. Battery has recovered. I am going to try this process on a very big battery.
Great video ive been getting free sla batteries like in your video from UPS units from a friend. Some have decent voltage some didn't. I watched other videos and was just useing distilled water. The results were very disapointing and furstrating. Thankyou for education. I just got my last batch of free batteries as my friend got a different job so no more free one. So perfect timing to find this. I recycled others incouldnt fix with the acid less process. I'm off the grid so this info is priceless to me. Side note I like seeing the kids electric vehicals I put two 24volt hoverboard batteries ran in parallel in my daughter's mini electric dirtbike it was to much fun to watch. Might try in series. Thankyou sir for the great video.
I had no idea that I could try charging the battery with another good battery in parallel. If I ever have a battery that does not want to charge I will try that. thank you very much Sir
God, that swamp of awful videos on this topic is deep. This video is the one you want, ignore all the others. Great work sir and thanks for making a to the point and factual video.
I like this guy patience it is a virtue. That parallel charging is how I saved my very expensive BMW battery connected together with a good battery put it on a charger overnight boom hold voltage before you can charge it all day all night it would not hold voltage past 10 volts now 12.56 solid
Thanks for the Video clip! Forgive me for chiming in, I am interested in your opinion. Have you researched - Lammywalness Trendy Trade Guide (do a search on google)? It is a great exclusive guide for learning how to recondition batteries at home minus the headache. Ive heard some awesome things about it and my BF after many years got great results with it.
Great video man! Thank you for showing the chemistry as people like to “theorize” fixes too much. Right now I’m working on multiple batteries that I’ve managed to desulfate with pulse currents, but I’m going to try and find some new Sulfuric acid which is hard to find around here. Thanks again! 💪👍🎉
I use " PulseTech" 110 Volt battery Desulphaters, they have worked great on 6 Volt, heavily Sulfated Trojan Golf cart batteries. I jump two 6 volt batteries together and use one 12 Volt pulse tech unit. I have three PulseTech units hooked up to my golf cart while not in use.After using the golf cart, I will charge up the cart pack of six 6 Volt Trojan batteries with the big cart charger, ( EZGO Total charge III) then check the battery water level in each cell and reconnect the PulseTech Desulfators. They have brought batteries back from the dead I've picked up at my local NAPA scrap battery pallet also. Sulfuric Acid can be obtained at any plumbing supply that sells building products for septic systems and cess pools which are still around in country areas etc. Septic tank/cess pool pampers will add a 5 gallon pal of sulfuric acid to a pumped out cell pool to break up the "bio mat" at the bottom to open it up and allow it to drain. So point is, sulfuric acid is available at one of these types of supply houses if your in a country area.
Good tips. I have a 5 AH battery which was bone dry and zero volts. Unknown age. Popped it open and added 1.25 mL acid per cell + water to top it off. Shook it around a bit to mix. Almost immediately it showed 7.5v. Now on a one amp trickle charger and slowly climbing in the charge current. Started out around 50 mA and already at 250 mA after running a while. The little trickle charger appears to be working fine without brute force jumpstart method required.
Hey would you be able to help me with my battery please? It’s been sitting for presumably 2 years, can I add 2ml of acid and top it of with water? And can I use my motorcycle’s alternator to charge it while I’m driving?
@@edoardo120 That might work but sometimes they get oxidized internally so it might not recover. 2 years is not that long so it may be fine. Mine was bone dry so if yours is mostly full you could try topping it off with just a little distilled water. I guess the amount of acid you add would depend upon that. For a bone dry 5 Ah battery, it was 1.25 mL acid per cell. If yours is rated at 10 Ah battery, then you would need 2.5 mL acid per cell (if it was bone dry). Otherwise it won't need as much, obviously. Yes, the motorcycle can charge it while running however it's better if you put it on a 12v trickle charger for a few hours before you try riding. You can always push start the bike too. Be careful about charging it too fast. 2 amp car charger should be fine. Just don't cook it to death on a 5-10 amp car charger. It will boil over.
@@nefariumxxx thanks, so how should I calculate the amount of acid needed for 12v 10ah battery? Is there a risk of putting too much acid? Amy safe and reliable way to do that?
@@edoardo120 If each cell is bone dry for that size, use 2.5 mL acid per cell and then fill the rest with distilled water. Wear eye protection and gloves to protect against splashing, outdoors when you do it. Careful not to make sparks when charging because the battery produced hydrogen which can explode. If your cells are not bone dry I would just try adding distilled water and seeing if it will take a charge.

Congratulations. Good explanations and diagrams. Excellent, steady camera views. Very good video! Thank you. Could use a bit more explanation, early in the video, to know when the process is completed.
I agree johnathan ..he has explained in a way that's easy to understand more about what the problem is and what is going on thru every step in what ends up being very informative and helpful video. Most people either expect you to just know what they are doing and why and leave you with very little useful information ...or they are to technical. To follow....or they dumb it down so much it's ridiculous ....i am proud you said something ...i am quite impressed with his video and would like to say thank you.
You are a fucking G my man, found you through the tire bead break video but this is something I need to do as well. Love your accent too, reminds me of my good friend’s dad 😇
Lol, you beat me to this comment. I wanted to say exactly the same. Definitely a great video and worth a sub, even though I haven't even seen what his channel is about...
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!
You also can use 18 volts at 500 nillamp to desulphate the plates this process takes 20 to 24 hours still using distilled water leaving the caps off to reduce pressure buld up.
Thanks for all the explanation. I might not get it but all good. I still haven’t had the guts to try this yet. But every couple of years I gotta buy batteries for my two project cars. Gonna try this method this year.
interesting points ,if anyone else is searching for vaginosis home cure try Jadonite Best BV Buddy (should be on google have a look ) ? Ive heard some extraordinary things about it and my m8 got great results with it.
Not certain about the points made but ,if anyone else needs to find out about how to recondition old batteries at home try Bablim Battery Booster (Have a quick look on google cant remember the place now ) ? Ive heard some pretty good things about it and my partner got great results with it.
I still can`t believe how great this battery reconditioning plan ( Check Details Here>>> t.co/Folp6e7Dkc ) worked. It worked on my drill battery, several AA and AAA batteries, and my camera battery; now they are useable again! This is very fun to do also. It really works for any kind of batteries!?
Great explanation, can't wait to try this! I also have a Victron Blue Smart IP22 Charger which would attempt to charge even completely discharged battery. I tested it already on my 18ah 12v battery that has a shorted cell the voltage drops to 10.4v soon after charging but it can be used and recharged. See what happens.
I was searching for an explanation on what's going on inside the battery chemically. I just don't understand the Epsom salt deal. Thanks for the video. I subscribed, even without knowing what your channel is about.
Very good video! I have some suggestions: 1. Don't fill the cell until you can see liquid water in the cells. This is an Absorbent Glass Mat (AGM) construction which has a fiberglass mat covering the plates. The mats are meant to be about 98% saturated with water, so you should fill them until the mats look damp (wet and shiny when you shine a flashlight into the hole), but not enough to have actual liquid water in the space around the plates 2. Water level always rises when the lead acid battery is charged. So when filling a sulphated battery fill it to the bare minimum, charge it so the water level rises, then top up to the correct level (if necessary) after charging 3. It was interesting that you added battery acid. In theory you should be able to use just distilled water, because the lead sulphate partially dissolved to become sulfuric acid.
It's sometimes necessary to add a small amount of acid since a small amount of sulphur is lost during the charge and discharge cycles. This is why you have to clean the terminals on a non-sealed battery and preferably coat them with anti-corrosion grease. If you want to go to the effort of doing this properly you would top up the cells with water, carefully stick a (preferably lead) probe in there and charge the cells individually, and then use a pH tester and add little bits of acid until the cells were roughly balanced. Not really worth it on a $20 battery, but it's essentially the same process that you would use on much larger, expensive batteries, so it can be good practice. I've been able to get over 10 years out of some of my automotive batteries by making sure to fill and balance them once a year or so. Over filling AGM cells isn't a huge problem, but do note that until enough electrolyte has evaporated to get them down to the proper level again you really need to make sure they remain upright at all times. So don't use this process on portable equipment batteries that might be tipped over. For stationary stuff though it should be fine as long as you don't fill them so full that they overflow during the charging process. Get one of those acid-proof containers to put them in like you would with a flooded battery until the level is proper again.
@@laurenceperkins7468 Very interesting ideas. I recently killed a car battery by not using the car for 2 weeks (it had already been deep-discharged 4 times and I managed to revive it, but finally one of the cells developed a short. Its specific gravity was only 1.1 when all the other cells were almost normal. No amount of charging got rid of the short). I have been wondering for days how I could have charged that cell to balance the battery. You say to put a pure lead probe and charge the individual cell, that's a great idea. How do you do that exactly? Say you want to charge cell #5. The lead plates are the negative plates, so I assume when you put a lead probe in cell #5 it will have the potential of the negative (lead) plates, so you connect that probe to the negative terminal of a 2V charger. Then you put the second probe in the neighboring cell on the side that's closer to the positive terminal (let's say cell #6), put a probe in the acid and use that as your positive terminal. If my logic is correct, the probe in cell #6 will be at the same potential as the lead plate (negative) in cell #6 and hence at the same potential as the positive plate of the target cell (#5) since those plates are electrically connected in series. Is that how you balance-charge a lead-acid battery?
@@LMF5000 More-or-less. Depending on the design it can be horribly difficult to get your probe on just one of the plates though. On some batteries they're quite close together. In that case it's often easiest to (carefully and with proper safety equipment) take the top off the battery. Balance charging won't fix your shorted cell though. That's a much more dangerous process. You either need to disassemble it and recondition the plates (with lots of lead and acid exposure potential) or the shop down the road from me used to top them up with fresh electrolyte and then put them in a special acid-proof, explosion-proof box and dump 200A at 90V through them briefly. The heating makes the scale crack off the plates and burns out any shorts... Or else the battery explodes violently... One of the two. Hence the box.
@@laurenceperkins7468 Oh, you poke the plate with the nail? I thought it was completing the circuit via the electrolyte not by direct metal-to-metal contact. Interesting re the box, but with the considerable dangers of sulfuric acid and lead, and the cheap price of replacement batteries (relative to having a horrible accident with an exploding battery), I've opted to recycle any battery that doesn't recover with conservative charging/discharging/adding water/Epsom salt treatment. Personally I draw the line at pouring out the acid as then I'd have to figure out how and where to dispose of it safely.
@@LMF5000 If you can poke the proper plate with your probe it works a lot better. Otherwise you've got what amounts to another cell of some type depending on the kind of metal the probe is. I don't believe the battery shop still does it for the same reason. The cost of cleanup when one blows is more than the cost of a new battery, so not worth it unless you have no other options. To dispose of the acid, neutralize it with baking soda and then you mostly just have salt and water. There will be a tiny amount of dissolved lead, so I wouldn't recommend drinking it or pouring it anywhere that will take it directly into the ground water. On the other hand, there are places where the ground water naturally has more lead than that in it... So what's safe from there depends a lot on where you are and how many batteries you plan to do this with.

What a fantastic video! It includes a thorough explanation, tutorial, and test. You have a great set of tools as well.
Hi, When I was gainfully employed, I maintained emergency services radio communication systems in the Highlands of Scotland. Some remote installations employed 12 and 24v dc solar/wind systems... Here are some tips I learnt the hard way! (when your up a gum tree without a paddle)
Most service techs carried a variable 24 volt 10amp bench power supply in their vehicles... When we found a dud 12 v battery that would not charge (open circuit)we would dismantled it as shown in the video... With a multimeter connected to the neg terminal.. the positive meter terminal was connected to a thin screwdriver ..the screwdriver was pushed gently into each hole to touching the cell plates, that should measure around 2volts then the next hole 4 volts and so on... increasing by approx 2 volts each time eventually you will find an open circuit cell (probably dry) top up with distilled water and let it soak for an hour ...Now replace the multi meter with the bench power supply and carry out the same process watching the current meter and adjusting the voltage to find the faulty cell causing the open circuit...Eventually current will flow between the positive and negative terminals...Now connect the variable power supply with a car headlamp bulb in series to limit the current ...Now crank it up to 24volts whilst watching the current meter gradually reducing the voltage to keep the current at around 2amps...Now charge the entire battery at 13.8 volts for a few hours (after topping up all the cells with distilled water) ... Finally replace the rubber caps and cover with a strip of gaffer tape...
At the next planned visit we would normally exchange the battery..
PS always wear safety glasses when doing this work!
🤩nice final drive 👍for 2 weeks I regenerate 4 gel batteries 12 v/20 ah with the addition of distilled water only, with a desulfator prototype made by me,
Can you share the design? Tnx
Thank you very much for this. You are the first guy on RUclips that I have seen to come up with real science to charge an old battery.
Caution, that is the best method, however, it does not work the vast majority of times;
After 40 years as a mechanic i tried everything on batteries; when they are sulfated they are JUNK; ONE cell dies,the whole set of 6 is junk,and it's a shame that the cells are not replaceable one by one, like with the lifepo4s.

This is how you make a good informative video, based on science, facts and showing receipts.
Thank you!
here's several tips for battery repairing
do not attempt to do this until you know what you are doing - the acid can burn you
check the voltage first - there may be a kaput cell which would waste your time.
Check the battery fluid.
Try to fully charge the battery.

I am a Retired Avionics Tech. I forgot more than I learned about Electronics these days. But seriously you have expertly explained the method to keep batteries going and going. You expertly put the correct information that is needed. Now if I can ONLY figure out how to revive an AGM Lead Battery now, LOL The many fires and being not good for Cold Climates without a heat source for them, that the Lithium's are famous for, has led me back to Lead, LOL
Amazing video: Science, Practical & Fun filled. All the ingredients of a successful online content.... Kudos.
This is the best video on YT about lead acid batteries refurbishing.thanks
Thanks for this! I was about to throw out 2 batteries I replaced from my UPS and realized I can revive them, thanks to you!
Great video. The chemistry explanation helps with understanding why simply adding distilled water can't rejuvenate a dried out battery that won't take any charge. I loved the tests at the end too!
The real issue is if the battery plates are sulfated or not. If the plates are not sulfated adding distilled water will give you a usable battery. De sulfating with a welder is a little dangerous if you don't realize that the gas coming out of a sulfated battery is not so bad "UNTIL" it starts a rolling boil and realize that the fumes now smell like rotten eggs and burn your eye's. The chemical reaction takes place changing the liquid inside the battery. Remember too that the pre sulfuric acid phase is Hydrogen and Oxygen which is not dangerous BUT for the fact that it is highly explosive if ignited at the concentration close to the battery body.
A fan and open area will avoid any issues there.
We used to always charge our dump truck batteries outdoors with a fan blowing away from us and obviously the caps popped off. You never want the batteries, boiling and building up pressure from what I understand.
Would love to see a list of all of this guys. Tools and supplies for conditioning has batteries. Still have not found a better educational RUclips video.
OMG. THAT WAS TOTALLY FULFILLING SEEING THAT ALL THAT WAS FOR YOUR KID. BUT HIM DOING WHEELIES ON 48V WAS AWESOME!!!!!!
There are many components to fixing a car battery. One place I found that succeeds in merging these is the Jons mender guide (check it out on google) without a doubt the most useful course that I have ever heard of. Check out this amazing site.

You have made an excellent, science based, no bullshit video. Thank you very much! Subbing based on this video alone.
FINALLY SOMEONE EXPLAINED IT CORRECTLY! THANK YOU!!
We waited long enough
There are actually few older videos as well as written guides. I've been doing this few years ago, sadly it doesn't fully revive dead battery and it will most likely die in few months. Capacity is also significantly reduced.

This was very helpful. Thank you for putting this on youtube. I have watched a bunch of videos on rejuvenating batteries. Yours was one of the most useful And helpful. I appreciate it. Thank you!
I brought up a dead Costco interstate with a 20watt solar panel and the exact same solar charge controller used in this video connected directly to the battery. I did add some distilled water. The solar charge controller will charge the battery at exactly .1 volt (1/10 of a volt) higher than whatever charge is on the battery. I think it is better than using another battery to parallel charge. It did take over a week, but this 5 yr old battery was completey restored to something a only little less than new operating power. I also had a brand new non-Interstate car battery and it would only rate between 11.9 V- 12.2V depending how recently I drove the car. When brand new I treated that particular brand new battery to some extra electrolyte in the form of sodium sulfate salt (Na2SO4) which is supposed to quadraple battery life. This didn't make a difference in the performance of the battery with normal car alternator charging. Info from Turquoise Energy did tell me to cycle the battery, but lead acid are not deep cycle and I just relied on the alternator. (Although this sodium sulfate salt chemical is what they use on deep cycle lead acid). It is only when I left a 25w solar panel/$12 charge controller on the battery for a month or more, did I experience sustained higher than average charge levels. In fact, after that, when the car sat for 2 month undriven and uncharged in any way during covid and rain with the battery disconnected, the battery still held 12.5 volts: better than new!! Sulfation is reversible, corrosion is not. Extra electrolyte might help but, it is the trickle charge at the right voltage that makes the big difference. (It is not advised to put sodium sulfate salt into an old battery as it might cause bits to dislodge and short out the battery)
Great comment. Someone else had a similar story with a battery that refused to revive after mag. sulfate and pulse charging sessions.
Spent a year on light shed led duty on a solar trickle charger and came back very close to new. Seems like desulfation can work but it can take a lot longer than people expecting to have an overnight fix for their ride's battery.
I'm impressed. 👏👏👏 for a change I can make sense of the battery restore process. Thank you 👌

Excellent video. Very valuable information. I tried this process on almost a dead battery. I had to use trickle charger instead a big battery in parallel. It took about a week for first full charge. Battery has recovered. I am going to try this process on a very big battery.
Beautifully presented, thank you so much! Loved the ending with your son hahaha!
way cool excellent excellent explanation excellent video on a subject that everybody talks about and doesn't really know
Thank you for your kind and patient video and/or explanation.
Great video ive been getting free sla batteries like in your video from UPS units from a friend. Some have decent voltage some didn't. I watched other videos and was just useing distilled water. The results were very disapointing and furstrating. Thankyou for education. I just got my last batch of free batteries as my friend got a different job so no more free one. So perfect timing to find this. I recycled others incouldnt fix with the acid less process. I'm off the grid so this info is priceless to me. Side note I like seeing the kids electric vehicals I put two 24volt hoverboard batteries ran in parallel in my daughter's mini electric dirtbike it was to much fun to watch. Might try in series. Thankyou sir for the great video.
seeing that kid enjoyed the extra kick from the amps, awesome!
Thanks! I'll be shopping for some sulfuric acid this week! I have a couple batteries that need some help.
I had no idea that I could try charging the battery with another good battery in parallel. If I ever have a battery that does not want to charge I will try that. thank you very much Sir

It is a great exclusive guide for learning how to recondition batteries at home minus the headache. Ive heard some awesome things about it and my BF after many years got great results with it.
Great video man! Thank you for showing the chemistry as people like to “theorize” fixes too much. Right now I’m working on multiple batteries that I’ve managed to desulfate with pulse currents, but I’m going to try and find some new Sulfuric acid which is hard to find around here. Thanks again! 💪👍🎉
Drain cleaner is 93 percent pure
I use " PulseTech" 110 Volt battery Desulphaters, they have worked great on 6 Volt, heavily Sulfated Trojan Golf cart batteries. I jump two 6 volt batteries together and use one 12 Volt pulse tech unit. I have three PulseTech units hooked up to my golf cart while not in use.After using the golf cart, I will charge up the cart pack of six 6 Volt Trojan batteries with the big cart charger, ( EZGO Total charge III) then check the battery water level in each cell and reconnect the PulseTech Desulfators. They have brought batteries back from the dead I've picked up at my local NAPA scrap battery pallet also. Sulfuric Acid can be obtained at any plumbing supply that sells building products for septic systems and cess pools which are still around in country areas etc. Septic tank/cess pool pampers will add a 5 gallon pal of sulfuric acid to a pumped out cell pool to break up the "bio mat" at the bottom to open it up and allow it to drain. So point is, sulfuric acid is available at one of these types of supply houses if your in a country area.
Would the acid not clean inside the battery
Thank you for this video..I’ve been looking for exactly this for a long time!
Superb! Great explanation and tech. I like the solar charger too. Good work!
This is one of the best explained videos I have seen...thank you very much!!!
Great vid,want test 2 similar batteries,hope I get same results,might try connecting it to work van as I drive during the week.
this guy is an absolute genius
Good tips. I have a 5 AH battery which was bone dry and zero volts. Unknown age. Popped it open and added 1.25 mL acid per cell + water to top it off. Shook it around a bit to mix. Almost immediately it showed 7.5v. Now on a one amp trickle charger and slowly climbing in the charge current. Started out around 50 mA and already at 250 mA after running a while. The little trickle charger appears to be working fine without brute force jumpstart method required.
Hey would you be able to help me with my battery please? It’s been sitting for presumably 2 years, can I add 2ml of acid and top it of with water? And can I use my motorcycle’s alternator to charge it while I’m driving?
@@edoardo120 That might work but sometimes they get oxidized internally so it might not recover. 2 years is not that long so it may be fine. Mine was bone dry so if yours is mostly full you could try topping it off with just a little distilled water. I guess the amount of acid you add would depend upon that. For a bone dry 5 Ah battery, it was 1.25 mL acid per cell. If yours is rated at 10 Ah battery, then you would need 2.5 mL acid per cell (if it was bone dry). Otherwise it won't need as much, obviously. Yes, the motorcycle can charge it while running however it's better if you put it on a 12v trickle charger for a few hours before you try riding. You can always push start the bike too. Be careful about charging it too fast. 2 amp car charger should be fine. Just don't cook it to death on a 5-10 amp car charger. It will boil over.
@@nefariumxxx thanks, so how should I calculate the amount of acid needed for 12v 10ah battery? Is there a risk of putting too much acid? Amy safe and reliable way to do that?
@@edoardo120 If each cell is bone dry for that size, use 2.5 mL acid per cell and then fill the rest with distilled water. Wear eye protection and gloves to protect against splashing, outdoors when you do it. Careful not to make sparks when charging because the battery produced hydrogen which can explode. If your cells are not bone dry I would just try adding distilled water and seeing if it will take a charge.
Can you just buy the acid without a license?

Thank god no epsom you’re a hero
Great explanation, can't wait to try this! I also have a Victron Blue Smart IP22 Charger which would attempt to charge even completely discharged battery. I tested it already on my 18ah 12v battery that has a shorted cell the voltage drops to 10.4v soon after charging but it can be used and recharged. See what happens.
It is in fact October 30th 2021 exactly 1 year later I just thought that was cool. I’d find it on this day. Also great video.
I was searching for an explanation on what's going on inside the battery chemically. I just don't understand the Epsom salt deal. Thanks for the video. I subscribed, even without knowing what your channel is about.
Epsom salts are an attempt to get the sulphate content of the electrolyte higher.
Very good video! I have some suggestions:
1. Don't fill the cell until you can see liquid water in the cells. This is an Absorbent Glass Mat (AGM) construction which has a fiberglass mat covering the plates. The mats are meant to be about 98% saturated with water, so you should fill them until the mats look damp (wet and shiny when you shine a flashlight into the hole), but not enough to have actual liquid water in the space around the plates
2. Water level always rises when the lead acid battery is charged. So when filling a sulphated battery fill it to the bare minimum, charge it so the water level rises, then top up to the correct level (if necessary) after charging
3. It was interesting that you added battery acid. In theory you should be able to use just distilled water, because the lead sulphate partially dissolved to become sulfuric acid.
It's sometimes necessary to add a small amount of acid since a small amount of sulphur is lost during the charge and discharge cycles. This is why you have to clean the terminals on a non-sealed battery and preferably coat them with anti-corrosion grease.
If you want to go to the effort of doing this properly you would top up the cells with water, carefully stick a (preferably lead) probe in there and charge the cells individually, and then use a pH tester and add little bits of acid until the cells were roughly balanced. Not really worth it on a $20 battery, but it's essentially the same process that you would use on much larger, expensive batteries, so it can be good practice. I've been able to get over 10 years out of some of my automotive batteries by making sure to fill and balance them once a year or so.
Over filling AGM cells isn't a huge problem, but do note that until enough electrolyte has evaporated to get them down to the proper level again you really need to make sure they remain upright at all times. So don't use this process on portable equipment batteries that might be tipped over. For stationary stuff though it should be fine as long as you don't fill them so full that they overflow during the charging process. Get one of those acid-proof containers to put them in like you would with a flooded battery until the level is proper again.
@@laurenceperkins7468 Very interesting ideas. I recently killed a car battery by not using the car for 2 weeks (it had already been deep-discharged 4 times and I managed to revive it, but finally one of the cells developed a short. Its specific gravity was only 1.1 when all the other cells were almost normal. No amount of charging got rid of the short). I have been wondering for days how I could have charged that cell to balance the battery. You say to put a pure lead probe and charge the individual cell, that's a great idea. How do you do that exactly?
Say you want to charge cell #5. The lead plates are the negative plates, so I assume when you put a lead probe in cell #5 it will have the potential of the negative (lead) plates, so you connect that probe to the negative terminal of a 2V charger. Then you put the second probe in the neighboring cell on the side that's closer to the positive terminal (let's say cell #6), put a probe in the acid and use that as your positive terminal. If my logic is correct, the probe in cell #6 will be at the same potential as the lead plate (negative) in cell #6 and hence at the same potential as the positive plate of the target cell (#5) since those plates are electrically connected in series. Is that how you balance-charge a lead-acid battery?
@@LMF5000 More-or-less. Depending on the design it can be horribly difficult to get your probe on just one of the plates though. On some batteries they're quite close together. In that case it's often easiest to (carefully and with proper safety equipment) take the top off the battery.
Balance charging won't fix your shorted cell though. That's a much more dangerous process. You either need to disassemble it and recondition the plates (with lots of lead and acid exposure potential) or the shop down the road from me used to top them up with fresh electrolyte and then put them in a special acid-proof, explosion-proof box and dump 200A at 90V through them briefly. The heating makes the scale crack off the plates and burns out any shorts... Or else the battery explodes violently... One of the two. Hence the box.
@@laurenceperkins7468 Oh, you poke the plate with the nail? I thought it was completing the circuit via the electrolyte not by direct metal-to-metal contact.
Interesting re the box, but with the considerable dangers of sulfuric acid and lead, and the cheap price of replacement batteries (relative to having a horrible accident with an exploding battery), I've opted to recycle any battery that doesn't recover with conservative charging/discharging/adding water/Epsom salt treatment. Personally I draw the line at pouring out the acid as then I'd have to figure out how and where to dispose of it safely.
@@LMF5000 If you can poke the proper plate with your probe it works a lot better. Otherwise you've got what amounts to another cell of some type depending on the kind of metal the probe is.
I don't believe the battery shop still does it for the same reason. The cost of cleanup when one blows is more than the cost of a new battery, so not worth it unless you have no other options.
To dispose of the acid, neutralize it with baking soda and then you mostly just have salt and water. There will be a tiny amount of dissolved lead, so I wouldn't recommend drinking it or pouring it anywhere that will take it directly into the ground water. On the other hand, there are places where the ground water naturally has more lead than that in it... So what's safe from there depends a lot on where you are and how many batteries you plan to do this with.
