I have the same problem as jeffwater. seldom use the car in the winter and battery is dead if I don't run the car every two weeks or so. I don't see a switch on the trunk light. is it possible the light remains on when the trunk is closed? a new battery did not clear the problem, so there must be a drain on the battery somewhere.

Hi, Car batteries lose their power over time if not used or charged. If you store your car in winter, take the battery out and give it a slow charge every month. (just like you do with a motorcycle battery). Or, start the motor and let it run 15-20 minutes every couple weeks. I would recommend doing that anyway to keep the engine oil from draining completely out of your bearings and possibly siezing up motor upon startup a few months later or bearing/engine damage due to excess wear on dry bearings. Thats the nature of the beast, there is no cure for it. Mike
