Never use any charger or battery that is damaged in any way.
•
Use the battery only for its intended purpose.
•
If you use the device near a network base station, it uses less power; talk and standby times are greatly affected by the
network signal strength 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's 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, as 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, as you will reduce the capacity and life of the
battery. Always try to keep the battery at room temperature. A device with a hot or cold battery may be temporarily inoperational,
even when the battery is fully charged. Li-ion batteries are particularly affected by temperatures below 0
˚
C (32
˚
F).
•
Accidental short circuiting can occur when a metallic object, such as a coin, clip, or pen, causes a direct connection between
the + and – terminals of the battery (the metal strips on the back of the battery)—for example, when you carry a spare battery
