Using the Batteries
Precautions When Using Batteries
●Never use any charger or battery that is damaged in any way.
●Use the battery only for its intended purpose.
●If you use the phone near the network’s base station, it uses less
power; talk and standby times are greatly affected by the signal
strength on the cellular network and the parameters set by the
network operator.
strength on the cellular network and the parameters set by the
network operator.
●Battery charging times depend on the remaining battery charge and
the type of battery and charger used. The battery can be charged and
discharged hundreds of times, but it will gradually wear out. When
the operation time (talk time and standby time) is noticeably shorter
than normal, it is time to buy a new battery.
discharged hundreds of times, but it will gradually wear out. When
the operation time (talk time and standby time) is noticeably shorter
than normal, it is time to buy a new battery.
●If left unused, a fully charged battery will discharge itself over time.
●Use only approved batteries and recharge your battery only with
approved chargers. When a charger is not in use, disconnect it from
the power source. Do not leave the battery connected to a charger
for more than a week, since overcharging may shorten its life.

for more than a week, since overcharging may shorten its life.
●Extreme temperatures will affect the charging capacity of your
battery: it may require cooling or warming first.
●Do not leave the battery in hot or cold places, such as in a car in
summer or winter conditions, as you will reduce the capacity and life-
time of the battery. Always try to keep the battery at room
temperature. A phone with a hot or cold battery may temporarily not
work, even when the battery is fully charged. Li-ion batteries are
particularly affected by temperatures below 0 °C (32 °F).

particularly affected by temperatures below 0 °C (32 °F).
●Do not short-circuit the battery. Accidental short circuiting can occur
when a metallic object (coin, clip or pen) causes a direct connection
between the + and - terminals of the battery (metal strips on the
back of the battery), for example when you carry a spare battery in a
pocket or bag. Short-circuiting the terminals may damage the battery
or the object causing the short-circuit.

●Dispose of used batteries in accordance with local regulations.
Always recycle. Do not dispose of batteries in a fire.
