Battery
Charge and Health
To check the battery charge, press and release 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 four lights are on, the battery has 80 percent of its charge remaining. If
no lights appear, the battery has no charge.
To check the battery health
using the charge gauge, 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.
