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...

Well, either way, the Trimetric was way off on that post capacity test charge... 238Ah vs 216, at over 8a current still being accepted... so a ways to go. I haven't given up on the meter though, as I only installed it last fall, and have not used the camper full time from then 'til now. And I imagine solar charging will likely throw it off even more? I should probably recalibrate it, but then again, I don't rely on Ah counting to tell when the bank is back to full... I rely on x amount of amps at y amount of volts, based on past results.
I bought the Trimetric at the same time I bought the pm4b-60... I would not have bought either one, if I knew then what I know now.
"You got up to 2V in battery surface charge"
I can imagine how that could make error correction difficult. Energy removed at say 12.3v average, but replaced at say 14v average.
'Til now, I had no interest in dealing in Kwh's, but IF there really is a relatively simple way of doing so, then I'm willing to venture off into that wilderness.
