I need to park my 2010 xc60 in the airport for about 10 days, and I suspect if the battery will still have the power to start the engine. It happened in winter that the battery ran out after not been driven for 2 days (I'm in New York). I suspected if there's electric leakage in the car, but the dealer said it was normal. So maybe some devices are using the battery even if the car is not running? I heard that the satellite radio is one of them, so I plan to remove the fuse temporally. Are there any other devices that I can disable without affecting driving the car?
