If your phone displays Not charging, charging is
suspended. Check that the battery is connected only to an
approved charging device. If the battery is very hot or
cold, wait for a while; charging will automatically resume
after the battery is restored to its normal operating
temperature. If charging still fails, contact your dealer.
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, since overcharging may shorten its life.
Important: If left unused, a fully charged battery will
discharge itself over time.

When is a good time to charge?

Actually, you can charge anytime. If you have a NiMH
battery, you should allow it to completely discharge once
in a while.
When your phone beeps once and displays Battery low,
you only have a couple of minutes of talk time remaining.
The repetition rate of these battery-low warnings depend
on the remaining battery capacity and the battery
condition. These warnings are more frequent when you’re
in a call.
Note: The phone will not give you the warning tone under certain
conditions. See “Warning and game tones” on page75.
Once all the power has drained from your battery, you’ll
hear three beeps with the message Recharge battery on
your display. At this point, your phone will switch itself
off and you’ll need to recharge your battery.

When is charging complete?

When the charge indicators stop scrolling, your
phone is considered fully charged. However, a
slight increase in charge may occur if your phone
is left connected to the charger for a couple more
hours. This is called “trickle charge” or
“maintenance charge.”

Charging times depend on the type of battery and
charger used.
For approximate charging and operating times, see “Batteries” on
page81.

Can you make calls while charging?

Yes, you can. But your battery may not charge while a call
is in progress (depending on which charger you are
using). Charging should resume once you end the call.
See "Chargers & Other Accessories" on page 83 for more
information.

Discharging NiMH batteries

A NiMH 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. The phone will display several messages that the
battery is low and that you need to recharge it; just
ignore them.
You can also use the battery discharge feature of any
approved accessory available for your phone. Do not
attempt to discharge the battery by any means other
than those just described.
Removing the battery
Note: Switch off the phone before removing the battery!
1. Press and hold the
button at the top
of the battery.
2. Slide the battery
toward the bot-
tom of the phone.
3. Lift the battery off
the phone.
