This new 100Ahbattery, only a few cycles, was brought to us by a boat owner who suspected something wrong. We tested this battery to BCI testing standards. The battery was charged to 1oo% in our lab, warmed to 77F (temp controlled water-bath), allowed to rest for 24 hours then a 5A constant load was applied and the battery was discharged to a 10.5V cut off. The battery could only deliver 72.27Ah. The customer states;
