Power The battery light displays charge status: ■ On: the battery pack is charging. ■ Blinking: the battery pack has reached a low-battery condition and is not charging. ■ Off: the battery pack is fully charged or not installed. For information about determining the amount of charge in a battery pack, refer to the "Monitoring the Charge in a Battery Pack" section next in this chapter. Monitoring the Charge in a Battery Pack Obtaining Accurate Charge Reports To increase the accuracy of battery charge reports: ■ Allow a battery pack to discharge to about 10 percent of a full charge through normal use before charging it. ■ When you charge a battery pack, charge it fully. The charge in even a new battery pack may be reported inaccurately until the battery pack has been fully charged at least once. ■ If a battery pack has been unused for one month or more, calibrate the battery pack instead of simply charging it. For information about battery calibration, refer to the "Calibrating a Battery Pack" section later in this chapter. Hardware and Software Guide 3-19
