Dead car? What the hell?

[Smevans]

It's bitter cold here in Calgary, -10 to -25 celsius temperatures, and I've had my car sitting for a couple weeks (I've been out of town working). A couple days ago it was warmer out so I went to take my car for a spin and discovered that my battery was dead. I checked the fluid level in the cells and they're fine and boosted the car yesterday hoping that things would be okay. The car started, I took it for a drive and today I went out to start it again and my battery is dead, door won't unlock.

Does anyone have an idea of what could be causing this problem? Oh yeah, I checked for lights I may have left on or anything like that.

Ummm, a bad battery perhaps?? Just because the water levels are ok, doesnt mean your batterys not bad, and thats hella cold, that will kill your battery even if it wasnt completely bad, also the fact that you let it sit for 3 weeks in that cold.
