Trick of COP calculation
#23 ·
I am not sure if this is the place or not to introduce Epsom salts to the line. Add a couple teaspoons of Epsom salts to the battery cells and try charging again. This wont help with charging on a conventional charge(although the article said it would) as I've seen but it works on the SG and SSG I've built. I had a winter battery that was empty from a boat charger boiling it out. It showed .08 volts and wouldn't charge on a conventional charger. I filled it up with spring water and no dice. Tried SG no dice. added Epsom salts with SG and it worked fine. I now have a good third battery although I don't have a battery checker it is good enough to turn over my 115hp boat motor for a long time. Another story!
