How would the cigarette lighter work? In every BMW I have owned the cigarette lighter is disconnected from the electrical system when the car is off.



P.S. Do yourself a favor and heed TJPark01's advice:
Quote:
Do both the registration and the battery tender. The registration tells your car the battery is new so it does not over charge the battery which will shorten the life of the new battery. This doesn't occur in a day/week/month, but it will slowly and systematically kill the battery due to overcharging it because the car thinks the battery is older than it is.
The number of people who will buy a $50-$70K automobile, throw in a cheap Walmart battery and totally ignore the manufacturer's advice to register the battery to the charging software that regulates the charging system in the car amazes me.
