[ 120 ]20 Do not short-circuit the battery. Accidental short-circuiting can occur whena metallic object, like a coin, a clip, or a pen causes a direct connection ofthe + and - terminals of the battery, which are metal strips on the edge ofthe battery.An example of short-circuiting could occur if you carry a spare battery inyour pocket or purse, where the battery could come into contact with suchobjects like a coin. Short-circuiting could damage either the battery or theconnecting object.Leaving the battery in hot or cold places, such as in a closed car in eithersummer or winter conditions, will reduce the capacity and lifetime ofthe 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 thebattery is fully charged. The performance of Li-Ion batteries is particularlylimited in temperatures below 0° C (32° F).The following list provides a guideline that you can follow:• When the operating time (talk time and standby time) is noticeablyshorter than normal, buy a new battery.• Use the battery only for its intended purpose.• Never use any charger or battery that is damaged or worn out.• Batteries must be recycled or disposed of properly.
