So this is now the second time in a row that my battery has died overnight, what the hell could be wrong?

I was in a slight fender bender on Saturday, but the car started fine Sunday and Monday. Now yesterday and today I come out to find a dead battery. What the hell could be wrong?

 

The only problem I know of that is electrical related is that I need a new starter. But its because the motor is sticking and it wont turn sometimes, maybe the solenoid has also gone bad?

 

I think this may be my problem

I had to manually put up my left headlight since the motor wouldnt push it up after the accident.

 

As long as the battery is known to be good, and the cable connections tight and no corrosion, check for battery drain utilizing either of the following 2 options. I keep this on file as it's asked quite often:

Connect a 12-volt bulb across the positive and negative battery terminals to test the bulb and the battery. If it glows brightly, then remove the negative battery cable and connect the bulb in series between the negative battery cable terminal clamp and the negative battery terminal. If the bulb continues to glow brightly, then start removing fuses or connections to the positive battery post one-at-a-time until the offending electrical component is identified by the bulb dimming.


A better approach is to use a DC ammeter inserted in series with the negative battery cable terminal clamp and the negative battery terminal. Starting with the highest scale, determine the current load. If the load is above 75 milliamps (.075 amps) after the initial surge, then start removing fuses or connections to the positive battery post one-at-a-time until the offending electrical component is identified by the parasitic load dropping to within 75 milliamps (.075 amps).
