Battery information
Note that a new battery's full performance is 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 the 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.
For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time
to time by leaving the product switched on until it turns itself off (or by using the
battery discharge facility of any approved accessory available for the product). 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 that is damaged.
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 15°C and 25°C (59°F and 77°F). 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.
Do not dispose of batteries in a fire!
Dispose of batteries according to local regulations (e.g. recycling). Do not dispose
as household waste.
