Battery Information
Your phone is powered by a rechargeable battery. Use only batteries
approved by the phone manufacturer and recharge your battery only with the
chargers approved by the manufacturer. See "Important Battery Information"
below.
STOP: A new battery must be charged for a minimum of 12 hours before being
used for the first time. A new battery's full performance is
achieved only after two or three complete charge and discharge
cycles!
See your cellular service provider or dealer for the battery options
available for your phone.
Installing the Battery
Insert the lipped end of the battery under the ledge at the bottom of the
phone then snap the battery down into place on the phone.
Removing the Battery
Note: Switch off the phone's power before removing the battery!
Press the release button at the top edge of the battery, lift that end
of the battery and remove the battery from under the ledge at the bottom
of the phone.
Charging the Battery
Plug the charger into a wall outlet and connect the charger to the bottom
of your phone.
When charging starts, the battery segments scroll and the phone beeps
once. You can use the phone during charging, but charging will be reduced
for the duration of the call.
Note: In a call, charging will stop completely if you are using the
Travel Charger (ACP-7).
After the segments of the battery indicator stop scrolling and all
segments are displayed, the battery is fully charged. Disconnect the
charger from the power outlet and phone.
If the battery is too hot or cold, the charging may be interrupted until
the battery reaches its normal operating temperature.
Note: With a new, completely discharged battery, the phone may take up to
45 minutes to show that charging is in progress.
Charging Times
The battery charging times shown in the following table are approximate.
Travel Charger Rapid Travel Rapid Cig. Lighter
Battery ACP-7 Charger ACP-9 Charger LCH-9
BKH-6 Extended 5 hours 90 minutes 90 minutes
NiCd 1100 mAh
BKL-6 Extended 5 hours 90 minutes 90 minutes

Talk and Standby Times
Battery operation times depend greatly on how you use the batteries, as
well as on the coverage of the network and network parameters set by the
cellular service provider.
Battery Talk Time Standby Time
BKH-6 Extended 2 hours, 5 minutes 30 hours
NiCd 1100 mAh
BKL-6 Extended 2 hours, 5 minutes 30 hours
Vibra NiCd 1100 mAh
BMH-2 Light 50 minutes 15 hours
NiMH 550 mAh
Discharging the Battery
A battery lasts longer and performs better if you fully discharge it from
time to time. To discharge the battery, leave your phone switched on until
the battery is drained and the phone turns itself off. Then wait for 30
minutes before connecting to a charging source. (See "Deep Discharge"
below.)
Note: Do not attempt to discharge the battery by any other means.
Battery Low Warning
You get this message and a warning tone when the battery charge is low and
only a few minutes of talk time remain.
The repetition rate of the battery-low warnings depends on the remaining
battery capacity and the battery condition. The warnings are more frequent
when you're in a call.
Note: If you've selected the Vibra Only or Silent Ringing Option, you
won't hear any warning tones. See "Ringing Options (Menu 3 1)" in
Faxback Doc. # 47263.
When the battery charge is too low for the phone to work, the phone
displays RECHARGE BATTERY, then beeps, then shuts itself off.
Charge the battery as described earlier in this section.
Deep Discharge
If you regularly just 'top up' the charge in your battery without ever
allowing it to fully discharge first, its life will be shortened. In order
to get the maximum life from your battery you should allow it to discharge
completely about once a month.
To discharge the battery completely:
1) Leave the phone switched on until RECHARGE BATTERY appears, then let
the phone Switch off automatically.
2) Leave the phone alone for about 30 minutes (and do not connect a
charger within this time) after it switches itself off.
During this 30 minutes, the phone is in "Deep Discharge" mode. The way
to 'wake up' the phone is to connect it to a charger.
3) Fully charge the battery after Deep Discharge.
The phone may remind you to discharge the battery, by presenting a series
of battery advice messages. Press (\/) or OK to page through the
information, or press CLR to clear the messages.
Important Battery Information
Use only batteries and chargers approved by the phone manufacturer.
When a charger is not in use, disconnect it from the power source. Do
not leave the battery connected to a charger for longer than a week;
overcharging may shorten its life.
If left unused, a fully charged battery may completely drain
(discharge) in 1-4 weeks.
Never use any charger or battery that is damaged or worn out.
Use the battery only for its intended purpose.
Do not short circuit the battery. Accidental short circuiting can
occur when a metallic object (e.g. coin, clip or pen) causes direct
connection of the two terminals of the battery (metal strips on the
back of the battery), for example, when you carry a spare battery in
your pocket or purse. Short circuiting the terminals may damage the
battery or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in
summer or winter conditions, reduces the capacity and lifetime of the
battery. Always try to keep the battery between 41 and 95 degrees F
(5 and 35 degrees C). A phone with a hot or cold battery may
temporarily not work (or charge) even if the battery is fully charged.
NiMH battery performance is particularly limited in temperatures below
14 degrees F (-10 degrees C).
Temperature extremes affect the ability of your battery to charge: it
may require cooling or warming first.
When the battery is not in use, store it uncharged in a cool, dark and
dry place.
The battery is a sealed unit with no serviceable parts. Do not attempt
to open the case.
It is recommended that you allow your battery to fully discharge
before you recharge it.
The battery can be charged and discharged hundreds of times but will
eventually wear out. When the operating time is shorter than normal,
it is time to buy a new battery.
Do not dispose of a battery in a fire!
Dispose of used batteries in accordance with local regulations. Recycle!
NiCd NiMH
Nickel Cadmium and Nickel Metal Hydride batteries must be recycled or
disposed of properly. They must not be disposed of in municipal waste.
