My battery keeps dying. About once a week my car will not start and has to be charged. The battery gets completely drained. Also if I don't start my car once a day this happens. My battery is less that two months old.

It sounds like you have a seat or mirror switch that is stuck on which will drain the battery down. Also if a CD is stuck int he player the battery will get weak overnight.

Here is a complete guide on how to find easy battery drains.

Hi:

I can't think of any small motors that are located there. However, if you hear something running, it is most likely what is draining the battery. Try this. Remove one fuse at a time until the noise stops. Then reference your owner's manual to see what circuit the fuse is for.
