The process below is what I Personally Use to recondition any "regular" lead acid batteries. It does work for batteries that have too much sulfite build up on the lead plates, to the point that it causes the resistance to rise until the battery is basically useless. OR in some cases, if you have battery that won't hold a charge, "slowly drains" when it is just sitting and nothing connected, *IF* its due to a so called "soft short" internally. Which basically means that there is enough sulfite/lead debris that has sunk to the bottom of the battery, and it has filled the catch tray until it is now touching more than one plate, this causes and internal short, and will drain the battery.

*DISCLAIMER: This is For INFORMATIONAL and EDUCATIONAL PURPOSES ONLY. DO NOT PERFORM ANY OF THIS YOURSELF. IF* you perform any of this, then you are accepting *FULL RESPONSIBILITY, * and hold me completely harmless in all ways, forms, and measures.

#1 - empty the battery of its original 'acid' into a bucket or other plastic container. Add baking soda to neutralize the sulfuric acid.
#2 - clean the entire top of the battery of any dirt or build up. Don't get the dirt into the open cells. Dirt on the top of a battery can actually become conductive and WILL drain a battery. This is why the top of any lead acid battery should be cleaned periodically.
#3 - place battery into some type of container that won't leak, like a plastic tote or something. This will catch any water that you spill when filling, or solution that may bubble over out of the battery.
#4 - Heat 1 gallon of water (this can be tap water, but distilled is always better, however this will not be kept in the battery) don't heat it so hot that it is boiling, just 100f to 130f (38c to 55c) or so.
#5 - Add approx 10oz of baking soda to the 1 gallon of hot water. Mix thoroughly until the baking soda is Completely Dissolved. Be careful if mixing in a closed container or bottle, as baking soda being mixed in hot water can build up some pressure.
#6 - Fill the battery, you may have to fill each cell slowly as sometimes it may react somewhat violently, especially the first fill. *Wear eye protection.*
#7 - When the reaction stops (almost no bubbling), empty and repeat this baking soda solution "wash" cycle at least 3 times, maybe more. The cleaner the water is when you empty the battery, the better.

#8 - Empty the battery of the final baking soda "wash" solution.
#9 - Fill the battery with **Distilled water**, put the caps back on and shake the battery good, remove caps, empty. Repeat this "rinse" cycle several times, to get any baking soda water residue washed out, along with any other debris that can be flushed out of the battery. When you empty the last time, the water should be fairly/mostly clear.

#10 - Lastly, heat 1 gallon of DISTILLED water, again to around 100f to 130f or so.
#11 - Mix in approx 12 oz of **EPSOM SALT** to one gallon of hot water, shake it up. Make sure the epsom salt is completely dissolved, which it should dissolve fairly easily in water at these temps. Be Careful if mixing in a closed container or bottle, as it may build some pressure, but usually not as much as the baking soda does.
#12- Place battery back into the tote or other plastic container. Place something, small piece of wood etc, under the "front" or "back" side of the battery so that it leans slightly in one direction. This will allow any solution that bubbles out to run off the side of the battery instead of "flooding" the top of the battery, as that would allow some of the charge being put into it to bypass the cells.
#13 - Fill the battery with the hot Epsom Salt Solution, and top off each cell.

#14 - Once filled, place the battery on charge. A "smart charger" will **NOT** work for this. You must have a plain old "dumb" charger that will "trickle" charge at low amps, usually 1 or 2 amps.

#15 - Put the battery on "trickle" low amp _(1 to 2 amps)_ charge. Charge for 24 hours.
#16 - After 24 hours, Temporarily disconnect charger. Check battery voltage with and without load. _(a Schumacher BT-100 battery load tester is currently $35 on amazon, always good to have for a number of reasons, but there are other methods of load testing a battery too, search YouTube)_ Write down the voltages. Top off any cells *IF* low with more Epsom Salt solution. Put the battery back on charge for another 24 hours. After 24 hours, recheck voltages, top off any low cells with Epsom Salt Solution, put back on charge.

Repeat this final step until the battery is *EITHER* putting out its full rated CCA _(cold cranking amps)_ capacity. *OR* until the battery "tops out" and the voltages do not rise anymore over the course of several days. This process may take a week or possibly longer before the battery will "level off". If the voltage Never Rises at all, or levels off at low voltages/low CCA... then your battery has a different problem, like a broken/disconnected plate or etc.

So Yes, this is not a "quick fix", and its takes some work. However, at the end of it, you usually will have a good working battery, for only a small $ investment.

And No, this does Not work with every battery, as there can be many different problems for why a battery goes "bad". But many batteries, especially if they aren't maintained or are allowed to sit for long periods of time without being charged _(like how lawnmower batteries usually are neglected all winter)._ As that is one of the reasons why the sulfite will build up on the plates to begin with.
*_*Side Note:_*_ Don't let a battery that is "run down" to be out in freezing weather, as if it is Very Low on charge, that means the "battery acid" is mostly water at that point, and the battery can freeze and bust the case._

However, even if it doesn't work on every battery, you can still save quite a few batteries using this process, and at the least extend a batteries life, sometimes as much as 4 years, which saves quite a few $$. Even if it only works for a few months to a year, it can get you by for a while, and can definitely get you out a pickle if no other means is available.

And YES, if the battery that you reconditioned starts to have problems again in the future, you can repeat this process and it should repair the battery again, so long as the problem is *still one of the two issues* that I described at the beginning of this post.

Hope this is a help to someone.

I love your famous youtube Musik hahaha ! The Spirit behind your Musik is soooo oo o full of love 2 New Science + Likes ....hahaha ! Bravo !

Here's an idea, just say pour salt water in it and charge for an hour.

[arminiuswarrior]

Dead battery can be charge when adding salt and disttiled water but the charge load will not last long coz of grounded circuit of plates have already damage and when over charge it will explode.

Bro, I respectfully tell you, beg you, supplicate you, do not use that choice of music in your life again. Is hyper annoying. I had to stop at 20 seconds to write you this comment because is horrible. Lets see if I can go back to watch your video.

Can we use inverter water instead of salt solution #plzreplyamericantech #americantech

[ΠάριςΑζής]

A) Salt destroys the lead acid battery. B) Only a few drops of electrolyte will never restore battery capacity. We talk about electrolyte. Not about medicine drops for curing caugh. C) Cutting the caps means destroying the mechanism of water reformation and increasing the possibility of electrolyte spilling around. D) This battery can only be used in vertical position only after that treatment. E) Charging for one hour and testing the battery for some seconds proves nothing about its health. You should measure its internal resistance before and after that treatment in order to reach a safe conclusion...

That is a joke...WATER AND worst bull I
ever seen on youtube.

I m hating informative vids with this silly background music 😐 it infected the world

[JamesBond-pbqy]

No gloves ?. He used a poker to get the blk caps off. Did he wipe them off ? I didn't see . So there would be acid residue on those caps if you didn't wipe them off and then you're touching them with your bare hands I hope he didn't wipe his eyes or his mouth or nose for any reason

[Cyberpuppy]

once the inner plates warp, and bend (or worse, touch) - the battery self-shorts and is, without internal mechanical re-tooling - VERY much dead. Pouring salts and "other gimmicks" don't repair neglect or poor servicing or mechanical/ design failure. End of story.

[mverdejr]

A 10 min video that could have just said, “add water.”

The salt (if table salt) is unnecessary and will eventually cause problems. Slicing the vent caps will also just accelerate dry out.

Nice video but fake idea hahaha .keep it up

Anything with fruity music like that gets a dislike from me.

Can I get better result if I add some seasonings! :)😀

Oh my God. Unwatchable due to pedophile music
