About a week ago, I accidentally unplugged the charge cord to my van, which took the batteries to way below 50% I don't know how long, but my battery monitor showed all kinds of lights and warnings that the power was sucked out of them.
To check for damage, I plugged the batteries in and let them charge for almost a week. At this point the float charge was 13.1. I unplugged the cord at 8:30 a.m. to start my experiment.
From Wednesday 9:00 a.m. the charge was 12.5 all the way to 10:30 p.m. where it showed 12.5. On 8:45 a.m. Thursday. It was still 12.5. At 5:30 it was 12.4, which I would estimate is about half of the batteries. At this point I plugged it back in again because I didn't want to take the chance that it would go to critical low state again.
Based on this, do the batteries seem pretty solid? They are 4 AGM 6 volts in parallel. The only thing running was an Engle fridge which eats about 1 to 2 amps per hour. I would rate my batteries at 400 to 450 ah.
Based on the fact that it took so long for the batteries to go from 12.5 to 12.4, do you think I could have gone another day in an emergency?
