Living with battery (to power TV, fans and charge phones)

Fastpaddler - I believe that most motorhomes (not all) will only charge the house battery if the "house battery switch" is in the "on" or "run" position. I set that switch to the "store" or "off" position if parked in my driveway and plugged into AC power. If not shut off, my charger is not smart enough to cut down the charging rate and will heat the water in the battery enough to vaporize the water. Some call it "boiling out the water".
