15. Battery and Charger Information
■ Battery Information
You device is powered by a rechargeable battery. The battery intended for use
with this device is BL-4B 700 mAh Li-Ion. This device is intended for use when
supplied with power from the following chargers: AC-6U. The battery can be
charged and discharged hundreds of times, but it will eventually wear out. When
the talk and standby times are noticeably shorter than normal, replace the
battery. Use only approved batteries, and recharge your battery only with
approved chargers designated for this device. Use of an unapproved battery or
charger may present a risk of fire, explosion, leakage, or other hazard.
If a battery is being used for the first time or if the battery has not been used for a
prolonged period, it may be necessary to connect the charger, then disconnect
and reconnect it to begin charging the battery. If the battery is completely
discharged, it may take several minutes before the charging indicator appears on
the display or before any calls can be made.
Always turn the device off and disconnect the charger before removing the
battery.
Unplug the charger from the electrical plug and the device when not in use. Do
not leave a fully charged battery connected to a charger, since overcharging may
shorten its lifetime. If left unused, a fully charged battery will lose its charge over
time.
Always try to keep the battery between 15°C and 25°C (59°F and 77°F). Extreme
temperatures reduce the capacity and lifetime of the battery. A device with a hot
or cold battery may not work temporarily. Battery performance is particularly
limited in temperatures well below freezing.
Do not short-circuit the battery. Accidental short-circuiting can occur when a
metallic object such as a coin, clip, or pen causes direct connection of the positive
(+) and negative (-) terminals of the battery. (These look like metal strips on the
battery.) This might happen, 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.
Do not dispose of batteries in a fire as they may explode. Batteries may also
explode if damaged. Dispose of batteries according to local regulations. Please
recycle when possible. Do not dispose as household waste.
