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...

Resting OCV's have improved dramatically. OCV was dropping down to 12.72 over just a couple days after a maintenance/top charge. I'm at my brother's place and have access to shore power :). I did another long charge Wednesday night, from 9:15pm 'til 7am Thursday. A 79 - 100%, which ended at 2.5a @ 14.3v (Should have been 14.4v float, so not sure why it was 14.3?). Assuming float kicked in around that 8+hr mark, the bank would have sat at ~ 14.4v float for about 1 1/2 hrs.
Since then, I've been periodically turning off the fridge (only load for the time being), to check OCV's. After nearly 23 hours of actual run time, at a little under 0.9a draw, Vbatt was 12.68v, and soc was 96% with 19Ah's removed... After a 45 minute rest, OCV was @ 12.76v. So things seem to be back to normal.
