Fairly recently I replaced my OEM battery with a new one. I haven't driven it for a few weeks and I noticed that it had died. The weather is quite nice here, so its not like the cold would drain it. I've checked all my interior lights to make sure they're not on, the headlights are off (not like it matters) so my question is what could be draining the battery?! Its pretty frustrating having to jump my car every time I need it.
For reference, the only real interior mods are a aftermarket headunit and some gauges.
