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.
