When is a good time to charge?
You can charge your battery 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 73.
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
while. This is called “trickle charge.”
Charging times depend on the type of battery and
charger used.
For approximate charging and operating times, see “Standby
and Talk Times” on page 76.
Can you make calls while charging?
Yes, you can. But your battery may not charge while a
call is in progress. Charging should resume once you
end the call.
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. Do not attempt to discharge the battery by
any other means.

Important Battery Information
•
The battery can be charged and discharged hundreds of
times but it will eventually wear out. When the operating
time (talk time and standby time) is noticeably shorter than
normal, it is time to buy a new battery.
•
Use only batteries approved by the phone manufacturer
and recharge your battery only with the chargers approved
by the 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,
since overcharging may shorten its life. If left unused a fully
charged battery will discharge itself over time.
•
(NiMH batteries only) 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.
•
Temperature extremes will affect the ability of your battery
to charge: allow it to cool down or warm up first.
•
Use the battery only for its intended purpose.
•
Never use any charger or battery which is damaged or
worn out.
•
Do not short circuit the battery. Accidental short circuiting
can occur when a metallic object (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 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, will reduce the
capacity and lifetime of the battery. Always try to keep the
battery between 59º F and 77º F (15º C and 25º C). A
phone with a hot or cold battery may temporarily not work,
even when the battery is fully charged. NiMH batteries’
performance is particularly limited in temperatures below
14º F (-10º C). Li-Ion batteries’ performance is particularly
limited in temperatures below 32º F (0º C).
•
Do not dispose of batteries in a fire!
•
Dispose of used batteries in accordance with any local
regulations.
