Default Battery Dead

I think I left my C6 out of reverse overnight and the battery was dead when I tried to start it. I charged the battery back up and drove for awhile to a restaurant. I ate dinner and came back out to a dead battery again. I had to get a jump, but drove the car for awhile again to charge it back up. Turn it off at home and tried to restart it and it started fine. Made sure I was in reverse and parked it for the night. Started it this morning and completely dead again. Charged it to full and let set for a couple of hours and battery dead again. Car is in reverse. Obviously something is draining the batter. Anyone had this problem before or have any advice?

You may have a bad battery. Charge it and then load test it. See if it holds a charge. If it is an 05, then you maybe due for a new battery.

It is an 05, but I have never had a battery problem before. This is a first. I can't believe this would have killed the battery. Has this been common with the 05 that the battery has to be replaced?

You may also want the dealer to do a parasitic draw test, see if there is any component or computer drawing more than normal mAmps after the car is shut off. I would definatley have them check the battery, charging system, draw test and any updates the dealer might have from GM.

These batteries do not take kindly to being discharged; I have heard of several that were toast after the first run-down. Are you under warrantee?
