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...

Using inverter loads to get 21.5 amps draw average over the 10 hours would be say 200w of 120v lights using the divide by 10 rule for inverters (yours might be a little different from that, they do vary somewhat)
Start with the 200w of lights at 20a and let it run so by the 5 hour mark amps are up to 21.5 and by the 10 hour mark amps are 23
SG is supposed to decline linearly with SOC down past 50% so you can use SG without worrying about "SG lag" like you get with a recharge.
