Re: Never charge your battery while it's connected to the car.
Emergency vehicles are often (or used to be) connected up to chargers and when the hand-brake was taken off the charging plug was automatically ejected so the vehicle could move off. No disconnecting the battery to charge it. I use an Accumate on the bike and cars with no problems. The modern BMW bikes can be charged with the battery connected although there's a protocol however to 'inform' the bike's ecu that the charger is connected.
