Referenceinformation
Do not short-circuit the battery. Accidental short-circuiting can occur when
a metallic object, like a coin, a clip, or a pen causes a direct connection of
the + and - terminals of the battery, which are metal strips on the end of
the battery.
An example of short-circuiting could occur if you carry a spare battery in
your pocket or purse, where the battery could come into contact with
such objects as a coin. Short-circuiting could damage either the battery
or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in
either summer or winter conditions, will reduce the capacity and
lifetime of the battery. Always try to keep the battery between 59° F
and 77° F (15° C and 25° C).
A phone with a hot or cold battery might not work temporarily, even if the
battery is fully charged. The performance of Li-Ion batteries is particularly
limited in temperatures below 0° C (32° F).
The following list provides guidelines that you can follow:
When the operating time (talk time and standby time) is noticeably
shorter than normal, buy a new battery.
Use the battery only for its intended purpose.
Never use any charger or battery that is damaged and/or worn out.
Batteries must be recycled or disposed of properly. Do not dispose of
batteries by putting them in fire!
When you disconnect the power cord of any accessory, grasp and pull
the plug, not the cord.
