acceptance charging rate AGM batteries
Hi all, It is generally thought that acceptance rate for a flooded deep cycle battery is about 12.5 amps per 100 amp-hours of capacity once the bank is at 85% state of charge. I know that accept...

Oh my. Last night at 0300 it was 78F. Mid nineties to 100, 3-6PM. With the ocean being 3/4 mile away this is not a dry air clime. I believe a few years ago I clearly stated when electrolyte was made inaccessible it vastly complicated the art of determining true state of charge. Things have not changed. VRB have an elevated voltage profile and do not bell-curve as profoundly as a flooded high antimony battery. There isn't a simple way or work-around. Construction and age variances plus capacity depletion would shatter a crystal ball.
