odd thing
 

My battery died while I was on vacation for 10 days. I was just wondering if that could have been caused by my system taking power while the car is off. Is that possible?

shouldnt!
winterpeg ... hmm was it in a shop? if not was it plugged in?
did u check it, did it have any voltage at all?

yes.
no, because it was in my garage.
I think it might have had the tiniest bit.

you checked made sure headlights and were all off?

ya, everything light wise and anything that would have drained power while the car was off was off.

What kind of car alarm do you have? Was it armed?

just the one that is stock with the car. it's an 02 maxima. And command start. and yes it was armed

I am pretty sure it was the alarm that did it. I had an 02 Chrysler 300m that was parked for a week with nothing but factory equipment and it was completely dead after a week. It was so dead it didn't even take a boost, it had to actually be charged up before it would start and that was just the stock one as well.

i had no idea an alram could take that much power. my school is on strike and the first week or so i didn't drive anywhere but when i finally decided to go for a drive my van started no problem
