I have bought a new battery every year for three years now. Just got a new Interstate battery a month ago. Leave the car parked for about 3 days and it drags when it starts like its almost dead. After driving it charges and cranks right up normal. If I run the headlights, fog lights, heater, radio, wipers back and front and sit idling about 5 minutes the battery light comes on the dash with a warning sound. I cut off the lights and it goes off for a few more minutes then comes back on. If I cut off everything its fine. All summer its always fine except at night. The battery light comes on after driving a while at stop lights and the heater dies down like the car is going to shut off. New Battery, New Alternator not rebuilt. 97,000 miles on the car 2nd owner. Never changed the radio or anything its all factory. Have hot wired where the door locks and headlights stopped working as others did online just bypassing where the wire went threw and that's all that isn't factory on the car. Thanks for any ideas on how to fix this problem.
