I have two new marine batteries which have only been used for 5 weeks. I fully charge both batteries at 25 amps, but they run down after two days to 25%.
I just bought a new marine battery. It came with 12.5v, 1.25 sg, I set the smart charger on 15A and when it went to float I measured the specific gravity of the fluid, the same as when I bought it 1.25. I set the charger to 2 amp and it seemed to be holding 2A, voltage indicated on charger was 14.6 but measured with meter was 14.2. Cutt-off to float is some % of charger setting so it cuts off early in 15A mode vs 2A mode. Impatient, I hooked up a manual charger for 15 hrs, final charge voltage was 15.3v and the sg had risen to 1.275. I believe I now have a fully charge battery.
