... I don't know if it is the charger or the battery. I just went over and check it and the light is still red. I felt the battery and it is cool but the charger is pretty darn hot.

My guess would actually be that the charger is bad.
In some sense, I would rather have the charger be bad than the battery:
1. The battery is a 9 cell NiMH, which is sort of unusual and not so easy to find.
2. A standard NiMH peak detecting charger will be better than the stock charger: the peak detecting variety will be able to charge that battery in 1 hour.
