Unusually fast battery drain problem

[SiFi]

Ever since the second week of owning the car, the battery seems to drain unusually quick. The only thing I had put in there was an alarm system and that should be drawing enough power to drain the battery after 2-3 days of non-use. Anyone else have this problem with their Matrixes? BTW, I got the 2004 XR two years ago. Thanks in advance for any reccomendations and suggestions.

Either the new alarm is draining the battery or
your battery won't hold the charge anymore.
It's kinda getting cold past week here in Boston and battery have to work harder.
Have the battery check out.

90% on that alarm.

Got it set to be sensitive? Could be going off at every car pass or door slam.

Or wiring could be jacked up (read, there may be a short somewhere)

we've had a lot of problems with toyota batteries. Our highlander go its battery replaced, my trix is looking to get a new one and so on. I'd unhook teh alarm system to clear that up first before whining to the dealer though.

Just disconnect the fuse from the alarm and see if the problem goes away.

The alarm isn't set too sensitive.. It's an AudioVox alarm... 795 if I can remember the model number correctly.

acrylucs, what's wrong with your Toyota batteries? Won't charge/ hold a charge?

Take it to an auto parts store, like auto zone, checker, kragen and get a free battery/alternator test. Guessing will just frustrate you.

pretty much. we left out highander untouched, not draining lights, nothing , for about 2 months, came back to a dead battery. it happened like 4 times, the dealer was clueless and saw the same results when we left it with them. my matrix also drains quick. it died once after a month of no use. no battery is that bad.

Already did that the first time the car won't start. They said the battery was good so I know it's something else. It doesn't really bother me that much. I'm not the one who has to drive it.

Nope. Not yet.. There isn't a fuse that I could pull to disable the alarm.. To do that, I would have to get to the brain and pull the power there. I was snowing all weekend here so I couldn't get around to doing that.
