2. The Battery
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.
New batteries must be charged with
the phone off for at least 24 hours
before initial use. A new battery’s
full performance is achieved only
after two or three complete charge
and discharge cycles!
Note: This chapter gives only the basics for battery usage.
See “Accessories” on page 48 for more information on
chargers and other accessories.

Removing a battery
Switch off the phone before removing the battery.
Charging a battery with Rapid Travel
Charger (ACH-4U)
1) Connect the lead from
the charger to the bot-
tom of the phone.
2) Connect the charger to
a standard 120V AC
outlet.
When the battery is charging, the battery
indicator on the right side of the display scrolls.
Allow the battery to completely charge.
Charging is finished when the segments stop
scrolling.
The charging times depend on the type of the
battery and the charger used.
See “Accessories” on page 48 for details.
When charging is finished, disconnect the charger from
the AC outlet and from the phone. When you disconnect
the power cord of any accessory, grasp and pull the plug,
not the cord.
Discharging the battery
Either leave your phone switched on until it turns itself off
or use the battery discharge facility of any approved

accessory available for your phone. The battery can be
charged and discharged hundreds of times but it will
eventually wear out. When the operating time is noticeably
shorter than normal, it is time to buy a new battery.
Battery Charge
The phone gives you a warning tone
and the message BATTERY LOW when
only a couple of minutes of talk time re-
main. When no more battery power
remains, you get a Recharge Battery
Tone and the message RECHARGE
BATTERY
. The phone switches itself off.
Connect your phone directly to a charger or place it on a
charging stand with the power on or off to begin charging.
Note: In some vehicles, the ignition must be on in order to
charge the phone with the cigarette lighter adapter.
If the message NOT CHARGING is displayed, charging is
suspended. Check that the battery is not overheated (over
104°F/40°C), too cold, or connected to a non-approved
charging device. Wait for a while, connect the charger to
the phone again and retry. If charging still fails, contact
qualified service personnel.
Important Battery Information
For good operation times, discharge the battery from time
to time by leaving your phone switched on until it turns
itself off or by using the battery discharge facility of any
approved accessory available for your phone. Do not
attempt to discharge the battery by any other means.
•
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 will discharge
itself in about a week at room temperature.
•
When the battery is not in use, store it uncharged in a
cool, dark and dry place.

•
Temperature extremes affect the ability of your battery
to charge: it may require cooling or warming first.
•
Do not short circuit the battery. Accidental short cir-
cuiting can occur when a metallic object (e.g. coin,
clip, or pen) causes direct connection of the + and -
terminals of the battery (metal strips on the back of
the battery), for example when you carry a spare bat-
tery in your pocket or purse. Short circuiting the termi-
nal may damage the battery or the connecting object.
•
Use the battery only for its intended purpose.
•
Never use any charger or battery that is damaged or
worn out.
•
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 59°F and 77°F (15°C and
25°C). A phone with a hot or cold battery may tempo-
rarily not work, even if the battery is fully charged.
NiMH battery performance is particularly limited in
temperatures below 14°F (-10°C).
•
The battery is a sealed unit with no serviceable parts.
Do not attempt to open the case.
•
Do not dispose of a battery in a fire! Dispose of used
batteries in accordance with local regulations.
Recycle!
