I have a 2008 Buick Enclave and a passenger last night ran the audio CD for at least an hour with the car either in accessory or in the run position, engine not running. This ran the battery down and needed a jump to get the car started. My questions are:
- Would running the audio system for an hour cause the battery to run down with in the key in the accessory position (with an in-dash gps)?
- Possibly, the passenger could have put the ignition in the run position (engine not running). Would one hour in the run position and audio system on cause the battery to run down? I think it would.
- More inportantly, how long would it take for car charging system to fully charge the battery? It seemed that it was fully charged today after running for a couple of hours.
Regards,
