I got a problem. My battery died, i replaced it, the next morning it died, replaced it again and same thing. Pulled out the multimeter and tested the battery with all of the fuses and the alternator and everything is fine. The battery pulls .2 amps when the car is off. I even unplugged my radio and amp and everything i could think of. When i replaced the dead battery the car alarm went off, i know this means something but i dodnt know what it is. What do you guys think is pulling my battery. I appreciate the help. Thanks.

It could be almost anything causing your drain.

The first thing i would do is disconnect the alternator and then check the drain.

Failing that , pull one fuse at a time till you don't get a drain, then investigate that circuit.

200mA is nothing to worry about. That will not drain a battery over night. You have a different issue. What is your battery voltage at rest? What is it with the car running with everything off? and everything on? It should not drop below 10v even with the heater on, radio up, or what ever else is on. It should be 12V at rest, 14V running and maybe 12V or so with everything on.

Many alarms go off once you put a new battery in if it was armed when the battery died.

Are those new batteries you put in or just different one?

Perhaps your alternator is not charging.
