Charge Gauge
Before you install a battery, press the status button on the battery charge gauge to illuminate the
charge-level lights. Each light represents approximately 20 percent of the total battery charge. For
example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights
appear, the battery has no charge.
Health Gauge
The battery operating time is largely determined by the number of times it is charged. After
hundreds of charge and discharge cycles, batteries lose some charge capacity, or battery health. To
check the battery health, press and hold the status button on the battery charge gauge for at least
3 seconds. If no lights appear, the battery is in good condition, and more than 80 percent of its
original charge capacity remains. Each light represents incremental degradation. If five lights
appear, less than 60 percent of the charge capacity remains, and you should consider replacing the
battery. See your
User’s Guide for more information about the battery operating time.
NOTE:
When you press and hold the status button on the battery charge gauge for at least 3 seconds,
the charge-level lights will first light to display the current charge status. Then they switch to Health
status where they represent incremental degradation when lit.
