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...

Before this gets too far out of hand, I wish to reiterate my thoughts of kWh monitoring of batteries. kWh monitoring of batteries is an augmentation of VOLTS, AMPS and AMPERE HOURS. It is not a substitute for any of them, and none of the alternates can render the same information as kWh. Establishing Peukert Constant is one of them. Understanding meaning comprehension) of the different energy factors between low antimony, high antimony, lead calcium and VRB absorbed glass mat, gel and sealed calcium batteries is another. I won't even touch on hybrids. The issue is comparing the battery to itself over time, and VA charge/discharge/time values.
