Reconditioning a 12 Volt Car Battery: 100% Success

Don't take this wrong, but you almost sound like Jesse James, but almost look like Kevin Smith (Silent Bob). Really that's kinda legendary lol. And thanks for the vid, sir this is good stuff.

Second video is up! I test CCA Amps and cut apart a battery so you can see the process. https://www.youtube.com/watch?v=RNnSYuTuLk4&t=46s

Making use of the youtube.com/post/UgkxcJ22tnHH9l1vjdIdEIG27iOG55P7L… reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

The true test is fully charging those batteries, then run them each with e.g. 20 A load (e.g. 4 headlight bulbs in parallel) until the voltage gets down to 11.0 V. You can then compute the total energy released to figure out how much capacity you end up with (basically the longer it takes the better the battery is). Simply being able to load the battery to correct voltage doesn't mean that you can do anything meaningful with the battery. A good car battery is rated between 50-120 Ah as new and if your reconditioned car battery has 2 Ah, it's practically not usable for anything even if it technically still works as perfectly good 2 Ah battery. If you truly just need 2 Ah battery, you should use NiMH or Li-on batteries instead.

Thanks! Like anyone researching any subject, I can take parts of your information and combine it with other videos, current knowledge, comments (neg and pos), and find more resources to double check safety and make my own informed decision. Having the guts to show your methods helps us all learn!

My car battery would not hold a charge but the cells tested fine. Put a tbsp of concentrated Epsom salt water in each, trickle charged overnight. Battery lasted fine with no problems and I sold the car three years later. I did not flush the battery or anything. My Dad did his lawn tractor battery the same way - still acting like a normal battery after 4 years.

Just looked at your video. And I enjoyed watching it! So many of us who owns cars, trucks, motorcycles, etc., for transportation, always thinks that when batteries goes dead, you must always spend more money again to but a new one. I've revived two very old batteries that were dead, by just hooking a 20 watt solar panel directly to them without a solar panel controller. And BOOM! Batteries still works, installed, and started a Dodge Caravan. And the other one is a backup. Someday I'll try your trick, and let you know how it works out!

I followed your advice and did this to my battery in my Jimmy. It quit holding a charge and would die after sitting a couple hours. Now is starting my car after sitting overnight. So cool. Thanks bud!

Hi all. I'm a mechanic of 27 years. Not everything in this video is correct. If you have an old battery, I can give some simple advice. ( But be assured, the battery will never be like new). You MUST use a "load tester" first, to document the condition of the battery. NOT a Multi Meter, but a LOAD TESTER, that you dial the correct CCA (Cold Cranking Amps) value of the battery as displayed on the label. Once you document the poor condition of the batter, now it's time to recondition it. 1) remove car battery and place is on soft ground such as your lawn. DO NOT open caps or remove any acid yet. 2) Roll the battery around over and over for several minutes. use your boot and kick the battery and make it tumble for a few minutes (this rough contact breaks a lot of the buildup stuck to the plates). 3) Drain all the liquid into a container holding the battery upside down to drain it all. Keep this acid and allow the dirty looking liquid to settle over a few hours, This will take time until the sediments settles to the bottom of your bucket. 4) fill battery with water and repeat process of rolling it after putting caps back on, but DO NOT keep this liquid! instead, dispose of this waste. 5) Once battery is empty again and the captured Acid part 3 has settled and looks clear, carefully pour the acid into another container, leaving lead sludge behind. Finally top up the batter with the clean acid and test the battery on a "load tester".. Yes you can charge it, but prior to doing so, test to see if there is improvement. I recently done this to a Pajero V6 Petrol, that had a dead battery. The Battery bounced back and I got 6 healthy months from it, but eventually it failed to hold a charge. No Epsom salts used in this process, however I am sure that will only improve the condition to perhaps give you as much as 12 months of life out of it, but I cannot verify that as I haven't used salts.

Thank you so much for taking the time to not only simplify, but also thoroughly explain the internals and operation of the batteries! Your explanation gives the viewers a better visual idea of what they're working with, and what they're trying to accomplish. Great video my friend, very informative!👍🏻

The coating in the battery is sulfur oxide. The metal looking debris is mostly lead and some of the steel grid that is imbedded in the lead plate to hold it all together. The Epson salt trick works 1 time. It somewhat removes the sulfur oxide, but over time will deposit magnesium into the plate.

I have some dead batteries and I am going to try that trick to see if it will work on the ones I have because I am tired of buying batteries for my vehicles and lawn mowers. Thanks for the tip and I am glad to have found you and I believe my charger will work on each of them and hopefully they will work again.

Nice video, thank you ! your time & adventurous kindness is beautiful

Thank you very much. Great info!

Great video, knowledge and safety is so important . My dads a marine engineer. He is a specialist with batteries. He loves his distilled water and Epsom salts. Great job😊👍🏽

Thanks a bunch will be trying this before buying a new battery.

Loved that joy u had at the end, starting your ATV. LOL

I tried doing this two ways. The first one I did I did it exactly like you did it but I used sulphuric acid because it was only $15 for 5 L. The second way I did it was I just drain the acid and then I refilled it with fresh sulphuric acid. I found your way works best. You really have to get that old crap out of the battery for it to be able to except and hold a charge thanks for the video I found it to be very informative peace out

Thanks mate, I am now a subscriber and I have the same safety shoes:)

Great vid...thank you for posting!
