I ran across this video.

My boss has an old Meter maid cart thing that he uses around his property and the battery died. It's a Napa battery and one of the cells wont come up even after 2 days on a trickle charger.
The other 5 cells are good.
Under a 100A load it would drop to 4v which won't start the cart.
I did the Epson salt trick and after 2 hrs it had 12.6V and dropped to 10V under a 100A load. Be interesting to see how long it lasts.
I wouldn't recomend doing it to a car you take into Death Valley or your kid drives but for a tractor used around the house it should be ok.
I'm going to check it again tomorrow. It's at the shop with a 1157 bulb burning bright. I'll put it on a trickle charge tomorrow and see what happens.
