When the battery is not in use, store it un- charged in a cool and dark place.

The battery is a sealed unit with no service- able parts. Do not try to open the case.

You can purchase additional standard or ex- tended capacity batteries through your local RadioShack store.

A battery can be charged and discharged hun- dreds of times, but it eventually wears out. When the operating time (talk time and stand- by time) is noticeably shorter than normal, it is time to get a new battery.

Leaving the battery in a hot or cold place, such as in a closed car in the summer or winter, re- duces the battery’s capacity and life. Always try to keep the battery between 59° and 77°F (15° and 25°C). A phone with a battery that is too hot or too cold might not work, even when the battery is fully charged, until the battery re- turns to a normal temperature. Nickel metal hydride (NiMH) batteries are particularly limit- ed in temperatures below 14°F (–10°C).

Use the battery only for its intended purpose.

Never use any charger or battery that is dam- aged or worn out.
