My car seems to kill batteries. I have gone through aprox. 4 batteries in the past three years. I believe something is constantly drawing off the battery. It is a 65 malibu. got a one wire alt. 700cca battery. mallory 6al box, what can I do to solve this problem.

Does the battery go dead if you don't drive it? Does it always go completely dead and you have to recharge it? To test for a draw, have everything turned off, disconnect a battery cable and hook a test light between the cable and battery. If the light lights, something is draining it. Make sure to disconnect any clocks or radios that need power for memory.

If I don't drive it at least like every two days it will be too drained to start the car. Right now I resort disconnecting the battery every time I park it.

Check your drain from the alternator.

Grab a 12v test light or DC amp meter, hook it between the negative terminal and cable, and start pulling fuses and unhooking things until the light or meter shows no draw.

Make sure you factor in dome lights if the door is open, and clock/radio if you have one as normal parasitic draw.
