One thing about the design of the car battery is that you can have ONE (or more) cells with higher resistance. This is known as "out of balance" the thing is that it can go down hill fast from there because the cell that NEEDS more charge will get LESS charge because of resistance in that cell. What I found is that if you up the amps, in my case it was over 70, the cell that needed the charge started to bubble. The cell the needed the charge was bubbling FAR LESS than the other cells, but I kept doing this for short periods of about 3~5 min, then let it cool. After about 20 times, going as far as 150 amps, the lesser cells would boil at a lower amperage and more than before, but still less that the others. This was the ONLY thing that brought the battery back to life. The tests were 1.5A float, 10A 1970s charger, new pulse battery 'fixer', DC stick welder. I also tried moving the acid from one cell to another and may or may not have helped, but both went down. Next test is a washout. Full charge, full drain into bucket, repeated rinse/flush of the battery to clean the crap at the bottom, then 150F water with epsom salt, full charge, then rinse again before restoring either the old acid or fresh acid. BTW, getting a marine or RV battery works in a car/truck and is a much better choice for a non-daily driver that'll sit a bit. One last note: the battery in question was NOT maintained with a regular maintainer and would require higher amps to keep it from dying off over about 10 days. It cranked a 460 truck engine with the lights on for over 30 seconds several times and was about 8 years old.

Lower the power after bubbling the salvation and make sure you keep edible to electrolyte in your plates when doing that, but don't do it.While you do that take it off the power source before you do that

I've seen a couple videos on this, but they were with a DC welder - is that what you have?

Yes, it's a welder/inverter. Here's a link to a better video I made kzbin.info/www/bejne/p6bWqGSkptCYhKssi=SpSSvIQGZ3jqzfat

Sorry for the abrupt ending. The main takeaways are: the tool to measure the Specific Gravity is on the left of the screen. It's about $8. The Stick Welder was about $300. After putting the battery back in my truck, I turned everything on for a couple of minutes (like headlights etc) and it was still 12.73V. Excellent results so far.

Hi there... I have experimented with this stuff and found that high amps is not so good... I now only go to 30 or 40 amps for a little bit longer... GdVd

I was taught to push 200amp into it 15 mins on rest for an hour a few times or more if needed I’ve done it a few times with good results

I tried that but I think I did it too long. This way seems pretty safe to prevent overcooking.

GOOD LUCK... The lead plates are POROUS from the factory and they CRUMBLE to the bottom of the battery,NOTHING can revive that... 30 years as a mechanic, i found only one way to revive a BAD battery: i trade it in for a new one NOTHING else works,IF it does no longer take a charge Is that your experience too?

It worked on 2 out of 3 batteries. Still working a year later.

does this work? what does it really do to the battery? I have a battery here from my truck that's in poor condition. my old battery charger doesn't work great any more, it tends to cook batteries if left on too long. that's what happened to my truck battery, forgot to turn it off over night, oops. what can I do to recover the battery? it's already shot, so no loss if it makes it worse.

I'm using a welder/inverter. The liquid acid crystalizes and sticks to the lead plates, this returns the crystals to liquid form. Some guys claim to have recovered batteries that are completely dead, 0 volts. Here's a link to a better video I made kzbin.info/www/bejne/p6bWqGSkptCYhKssi=SpSSvIQGZ3jqzfat

would battery charger work? one with wheels on.

The old analog style might, but most these days have a timer that shuts them off after a couple of minutes and you're limited on what amperage setting you use. I tried my battery charger once and overcooked it. I like being able to adjust the amperage to get as close to 16.5 volts to slowly cook it. 200 amps seems way too hot. If you're gonna try the battery charger, maybe just run the 200 amp booster for two minutes and let it cool for eight, like a 20% duty cycle. Just be careful, and if the battery is bad it's bad, doesn't hurt to experiment.
