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...

BFL,
It has occurred to me, it could be a simple matter of how the Trimetric interprets the info one enters into it. For example, I can put in 430Ah as the bank's capacity, but not 215Ah. And then there are those parameters like amps at a particular Vabs, that constitute 'full'. Even the Trimetric is guess-timating to a degree, it seems.
Its Ah countdown appears to be very accurate, but when it comes to Ah's replaced, its accuracy seems to change, based on depth of cycle. And seeing as I will not be doing identical cycles daily, it may be difficult to choose an appropriate % of loss? But, hopefully with time and practice, I'll get a better hold on things.
I do not set the three things. I don't like they way they treat full as being less than true full. I just get AH, volts, and amps. So no % full reading. I compare the AH count SOC with the "morning voltage" to see if they "match" for SOC
I know the bank capacity roughly, so I can get the % if I want it from the AH. On a good sunny day, when AHs get back to zero and then go over to plus something, I reset to zero at sundown.
I could do the adjustment for that but not worth the bother to me the way I use it.
