I turn my conditioner off when we're away . Although it stops charging when the battery is full it remains live. It makes no sense to turn it off like this because it might equally cause trouble while I'm at work or in bed. There was a case a while ago where a dehumidifier burnt out and although it didn't burn the garage down it covered the car in black soot and ash and ruined the paint. So I turn as much as possible off when we're away. Paranoid? Moi?
