Charge Gauge
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 
"
for more information about the battery operating time.
