Well then, I guess I have nothing to fret about. I was thinking 12.9v was fully charged.
Thanks!
My CG2 are 12.92 rested. My GP 31 are 12.76 rested.
A couple years ago I got a couple of the same CG2 batteries. They were heavily sulfated. I was able to get SG up to 1.270ish.(my new GG2 show 1.300) Rested voltage was 12.6 at just 5 amps after a bit voltage would sag to around 12.00 volts pull the amps and voltage. would rise to 12.5. Are the ends of the batteries round (this is a sign of sulfated plates)
