If your batteries are plugged in all the time there is a chemical action taking place to keep batteries charged which means shedding of the lead plates. I realize more batteries die from undercharging (sulfation) than from overcharging (plate loss) but does anyone know how much plate loss there is from maintenance charging, like so many thousandths /day? I have never seen this posted here.
Prior to getting the full hook ups at home, we never had the RVs plugged in all the time, our batteries lasted about 5 years. Now that we have the full hook ups at home, our batteries last about 5 years.
