About Batteries Battery and Dual Battery Support When the external power adapter is not connected, your computer draws power from a PowerBook battery in the battery bay or expansion bay. You can also insert a second battery in the expansion bay to double the amount of battery life. Monitoring Battery Charge Level You can determine the charge left in your battery by looking at the battery level indicator lights on the battery itself. The charge can be checked whether the battery is in the PowerBook or not. The lights glow to show how much charge is left in the battery. A lighted circle indicates that the battery has power; an unlighted circle indicates lack of charge. The indicator lights remain lit for a few seconds after you press the battery level indicator button. Choose Mac Help from the Help menu and search for "battery. " Apple Computer, Inc.
