Charging your new battery
Your phone can be used with either a rechargeable Li-Ion
or NiMH battery. Note that a new battery’s full performance
is achieved only after two or three complete charge and
discharge cycles.
With your phone powered
on or off, connect the lead
from the charger to the
bottom of your phone.
You can also place your
phone on the charging
stand (with the stand
connected to a standard
120V AC outlet via either the ACP-7U or ACP-9U AC/DC
adaptors).
When the battery begins charging, your phone will beep
once and the battery strength indicator on the right side
of the display will begin to scroll after a few seconds.

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 page 80.
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 page 97.
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 and other accessories" on page 99 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.
