Capacity Testing and 20 HR Rating
I'm thinking about doing a capacity test on my four GC2's. They have a 20hr rating of 215Ah. One thing I'm curious about is how the 20hr rating would have been determined. Being 6v, would they h...

Did another 70~99%, down to 3.7a @ 14.4v. Charger dropped into float at the 8 1/2 hour mark. At a P10 setting of 86%, charge ended at 101% and +5Ah's... So, very close... will try an 85% eff setting next. Amps tapered quite early though; in the low 80's % soc range (about -70Ah), so gonna try raising Vabs a little.
Just to clarify my intentions, I'm curious to see if there is a pair of settings that will record amps as tapering at a point where charging amps = missing A'hs, regardless of charge rate. So, if I can get the Tri to zero out just before float is engaged, and at a Vabs setting that has 45 amps beginning to taper at 89%/-45Ah's, then I will switch to the 75a charger to see if 75 amps begin to taper in the 82%/-75Ah range, at the same Vabs setting.
