Important 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 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.
