Avaya Inc. Desktop Charger, Dual Charger, and Quad Charger User Guide
Battery Packs
Overview The WT will need to have its Battery Pack recharged
periodically. The Nickel Metal Hydride (NiMH) rechargeable
WT Battery Pack gives you four hours of talk time or 80 hours
of stand-by time (unless PTT is enabled in the 3626 Wireless
Telephon only). Stand-by time is when the handset is turned on,
but not in an active call.
Indications of low
battery
The WT will notify you when the charge on the Battery Pack is
low by displaying the battery icon. If you are in a call you will
hear a soft beep through the earpiece every thirty seconds. The
user has 15–30 minutes of battery life left. The alerts will
increase to every six seconds when there is about one minute of
battery life left.
Not in call: The message Low Battery and a loud beep indicate a
critically low Battery Pack charge. These occur when the user is
not in a call. The WT will not work until the Battery Pack is
charged.
Caution: Take care not to short the battery contacts on the Battery Pack
with metal objects such as coins, keys or paper clips. Shorting
the contacts can cause permanent damage.

Pack removal and
replacement
To remove, press down on the latch on the Battery Pack on the
back of the WT. The Battery Pack releases outward.
To replace, slide the lip of the Battery Pack into the bottom of
the cavity. Push the top of the Battery Pack until it snaps into
place. You should not have to force it against the WT.
3626
Battery Pack
removal and
replacement
To remove, hold the handset in one hand with the keypad facing
up. Press both Battery Pack release buttons (on the left and right
sides of the handset) at the same time. The Battery Pack will
release downward. You may catch it with the palm of your other
hand. If the Battery Pack does not release, gently shake the
handset while pressing both release buttons. Do not pry.
To replace, slide the Battery Pack straight into the cavity until it
snaps into place. You should not have to force it against the WT.
Changing the Battery
Pack while in a call
If you are using the Telephony Gateway in your telephone
system the Battery Pack may be changed while the call is still in
progress. Do not press End Call on the WT. Quickly remove the
discharged Battery Pack and replace with a charged Battery
Pack, then press Power On to turn the WT back on. Press Start
Call to resume the call in progress.
Battery Pack note Battery Packs are not interchangeable. The 3626 WT uses the
distinctive square model BPX100 Battery Pack. The Battery
Packs for the 3616 and 3620 WTs are the same rounded shape
but different colors. The 3616 model BPE100 Battery Pack is
black; the 3620 model BPN100 Battery Pack is steel blue.

Important:

Only use Avaya Battery Packs with Avaya WTs.
