Dead Battery

[Drewe30e]

So I haven't driven my car in a while and yesterday it wouldn't start (dead battery). After a jump everything was fine. However, I tried to start it again today and the battery is dead again. The battery is fairly old (3-4 years old) and probably should be replaced. The only thing that worries me is that it died in just over 12 hours. Could this solely be the battery or do you guys think I have a drain somewhere?

A battery that has experienced one or more full discharges will have significantly reduced capacity. And it isn't uncommon for an aged battery to fail to recover from a deep discharge. Replace the battery, and invest in a battery tender for those times when you won't be driving the car for a week or more.
