I am having a serious problem with my 1994 Camaro. If the car is not driven within a few days, the battery is completely drained. I have been through two diehard silver batteries and two autozone gold batteries. The car has an alarm (with keyless entry), remote start (which doesn't work), and a truck mounted CD changer, other than that it is bone stock. I'm not sure what kind of shop to take it to to find out what is killing the batteries. I took the 2nd autozone one out today and it will not charge, it is reporting a bad cell. The battery is less than one month old and only driven twice. If the car is driven everyday it seems the alternator keeps it charged enough.

Any help would be appericated.

Disconnect a battery cable and insert a 12V test light. The glow of the bulb will show the amount of current being sucked from the battery.

After connecting the test light, disconnect those accessories one by one to see which one is drawing the current, bulb glows less. You've located your power sucker.
