Backup Battery
A new backup battery should last for approximately five (5) years, but the life of any
backup battery can be adversely affected by environmental conditions like moisture
and heat. To get the longest service from your backup battery, do not place the AT&T
Wireless Internet device in direct sunlight or in wet or extremely cold environments.
To test the condition of your backup battery, make sure the AT&T Wireless Internet
device is powered on. Unplug the AT&T Wireless Internet device from the wall
power outlet. If the Battery light turns red, then the backup battery may need to be
replaced. If the AT&T Wireless Internet device does not remain on once unplugged
from the wall power outlet, then the backup battery needs to be replaced.
It is recommended that you test your backup battery charge at least once per year
and replace it if necessary.
