Battery Dying, but okay????

Egan,

I have the same problem. Many years ago I was a car audio installer. One thing I noticed is the H2 pulls a lot of amps. Think how many 12v bulbs are lit with the ignition on and a door open. Add a very high amp pull during start up and we are hard on batteries. I found once I cycle a battery a couple of times it is pretty much shot.

As mentioned, I would pull the radio and amp fuses and see if it is killing the battery. If it doesn't, then I would look at replacing the battery.

Onstar is a know culprit too.
