I am usually very good about not discharging the batteries too far and getting them back on the charger as soon as possible in order to maximize life. Earlier this week I screwed up.
I was in the garage working on moving waypoints and when I was finished I turned off the graph but forgot to turn off the main power and the network. I didn't find the mistake for a couple of days. At that point I shut everything off and checked the battery voltage before plugging in the charger. It was down to 11.98v.
Battery is the Duracell AGM Group 31. It appears to have charged up without a problem and has been holding at 12.92v. Can I expect this battery to fail sooner than it would have without this issue?
