Just had to get jumped yesterday. I didn't leave the lights on or anything, and the battery is about 8 months old. After the jump, I drove to the mall and got a haircut. Was in the mall for maybe 35 minutes. Car starts up fine. Went to gym for maybe 40 minutes. Car starts fine, went home. 10 hours later, car doesn't start. Seems like something relitively small is draining the batter when it's shut off. I say relatively small because it'll start up if the engine is off for a little while, but not if it's off for several hours. Kind of like leaving the dome light on, except it's not on. How can I check for sure if the battery is slowly getting drained while the car is off? This can't be a battery or alt problem, can it? The volts seem ok while driving.

your alternator might actually be failing.

Id get that checked out
and then id start checking the wiring.
