Well, I wanted to see if I could bring back from the dead some deep cell 12V batteries. I found I was just killing myself trying to bring Nicads back to life. Here are the results of attempting to bring two batteries ( Named Spark and Neon ) back to life.
Tested with inverter with 13W light bulb is pulling .58 Amps

I was VERY happy tonight to see that Neon lasted so long. What surprizes me is the acid in the cells in Neon still test bad?
But I guess I still have a long way to go before the sulfate on the cells returns back, I understand about 30 to forty recharges.
So, I am a believer that this will work to recharge batteries from the dead, I am getting 3 more cells, and hope to move on to golf cart batteries next.
Does anyone have a schematic for using more than one coil, or transistor? now have 4 ssgs, and I want to move up to the best way of charging these, and open to ideas. peace
