Also at idle, if i slowly rev through the rpms up to 2k, it sounds like almost a whine noise. Not real loud but i can hear it from inside the car with the radio off. Let me guess my alternator is dying..

As for the battery issue, it could be the current sensor acting up.

For the whine, it could be an idler pulley.
