Does my MacBook need to be powered ON for these first two steps?
Thanks.

1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.

2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.

That is an awful lot, and is probably the cause. You should calibrate every month or so.

Yea I know! Im on a some what "vacation" in Arizona until March. Ive been here since October and all I really do is use my computer.
But whatever, its just a battery. Im not to worried about it I guess..
 
How can you find out the health of your battery, mine is charging at the moment but im interested to find out the health percentage.
