What can drain the car battery when the car is off? Headlights or dome lights left on. Your battery is already weak or in poor condition. Severely corroded connections. Draining on your electrical system such as glove box or trunk light that doesn’t go off. Extreme temperatures either hot or cold. Lose belts or worn tensioners prevent alternator to work properly. You could have a charging system problem. Todays vehicles require a greater amount of reserve capacity when the engine is off.
