Sounds like the alternator is going bad. Your battery shouldn't be providing any electrical power once your car is started. It's up to the alternator to do that. Better check the battery with a multimeter also. Since the alternator also charges the battery, if it's bad then the battery will start to go south too. Anything under 11.6V with the car off and the battery won't hold a charge. <---Going from memory with the voltage but I think that's the number.
