I got these two sla batterys from a ups that was left on and drained to 0 volts.
I have got them to charge to around 12.3 volts but when I try to go to 13.8 they start to get very warm about 30 to 40 c at 1 amp.
I have been charging them at 400ma and they still get warm and voltage does not seem to increase should I just give up?
