Chapter 2: Battery installation and removal
■
Maximum backup battery:
provides up to 18 hours (6-cell) or 24 hours (8-cell) of backup
time, depending on model and usage. It replaces the battery door and increases the
height of your telephony modem by about 5/8" (16 mm).

Maximum battery installation and replacement
(page 20).
Note:
The backup times shown here are only an estimate and assume that your
battery is fully charged. If your battery is partially discharged (for example, if it is
in the middle of a self-test or is not yet fully charged), then your backup time will
be reduced.
Basic battery installation and replacement
Your telephony modem provides continued telephone service during power outages. The
battery backup is not intended to take the place of AC power.
To install and replace the backup battery.
1. Press down and pull back on the latch holding the battery door (on the bottom of your
telephony modem ). Pull the door toward you. Set the door aside in a safe place.

Risk of equipment damage
Improperly inserting the battery may
damage the battery connector in your telephony modem. Carefully follow the
instructions in the next step to avoid damage.
2. Hold the battery pack so that the guides on the battery align with the slots on your
telephony modem and slide the battery into the bay.
