For starters, I've put a quart of water in the "good" set and and two quarts of water in the other ... I don't think that the guy that owns the golf cart knows that batteries need water.
The first pair charged for four hours at 25 amps and then ran at diminishing current for three more. I have the second pair on know. I'm thinking to get as much charge as I can into all of them and then to do more testing.
