I have a BMV-712 connected to a 450 amp hour lead acid battery bank (Trojan t-105’s). Recently When I run my battery charger to bring the batteries to a fully charged state I’ve noticed that the consumed amp hours still read 40-50 amp hours consumed when the BMV synchronizes and resets the battery to fully charged and resets consumed amp hours to 0.
in other words I’m using 100+ amp hours over night but only registering a return of about 50-60 amp hours back into the bank when I fully charge them.
Is this normal?
Both my solar and my AC-DC battery charger bring the batteries to 14.82 volts for a specific time based on previous day’s discharge and then reduce batteries to 13.5 volts with minimal amps to sustain this. I have adjusted my battery settings because before I was getting fully charged status too early.
