15 Reference information
This section provides information about your phone’s batteries, accessories, chargers,
safety guidelines and technical information. Be aware that the information in this
section is subject to change as batteries, chargers, and accessories change.
• BATTERY STATEMENTS
Charging and discharging
Your phone is powered by a rechargeable battery.
Note that a new battery's full performance may be achieved only after two or three
complete charge and discharge cycles!
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. Unplug the charger when
not in use. Do not leave the battery connected to a charger for longer than a week,
since overcharging may shorten its lifetime. If left unused, a fully charged battery
will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge; allow it to cool
down or warm up first.
For good operation times with NiMH batteries, 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.
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 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 59°F and 77°F (15°C and 25°C). A phone with a hot or
cold battery may temporarily not work, even when the battery is fully charged.
Batteries' performance is particularly limited in temperatures well below freezing.
