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 top 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 objects such 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 15°C and 25°C (59°F and 77°F).

A phone with a hot or cold battery might not work temporarily, even if the battery is fully charged. The performance of 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.
