You need more info, install anything recently? Any past battery problems?

But to answer your post, You have a parasitic drain, have fun tracing it. /thread.

How do you know the battery is eating? Is there a munching sound coming from underneath the hood?

Personally I don't find the oxidation mixed with road grime to be very appetizing. Plastic is yuck. This is better eating:

Hahaha...

Put the car in a dark garage and see if any "off" lights are faintly glowing. The turn signal/light switch stalk on one of my past cars had become worn so the light switch was just loose enough to make contact. Not enough to fully light the headlights but enough to complete the circuit.

Otherwise, any number of your add-on accessories will need to have the wiring checked.

i'm assuming it stops eating if the car is on (?). sounds like some sort of obsessive compulsive disorder.

since the car has a factory alarm, that will always put a draw on the battery while the car is off and it is armed. also the radio and ecu have power lines that are constant for memory purposes etc...., then theres the posibility you have something thats being left on for whatever reason.

Did you ever get the front of the car fixed? It could be when it was in the accident that some wires got cut or stripped and their getting grounded out or something. Check every wire in that area. I hate electrical problems but it usually turns out to be something stupid, but simple. Mysterious draws are a PITA, good luck.
