hi i have got myself a ctec xs 3600 this year for my car ,i still use the car over winter but only very good days,is it safe to leave it on conected via the cig lighter socket all the time,dont want to blow me car or gararge up,its putting charge in at the moment but i expect it to switch to maintainence soon,i know its a daft question, but i worry about doing some damage.many thanks pete
