Tips for improving battery performance
Do not disassemble or short-circuit the battery.
Keep the metal contacts at the base of the battery clean.
If you have not used an internal or external battery for more than a
month, recharge it before using it.
Ask your local Kyocera Service Center to replace the internal battery when
it no longer maintains a charge.
Do not use any battery in direct sunlight or in places with high humidity,
such as the bathroom.
Never dispose of any battery in or near a fire. It could explode.
Do not charge any battery if the temperature is below 32ºF (0ºC) or above
122ºF (50ºC).
Do not store any battery in hot areas for long periods of time. Use these
storage guidelines:
under 1 month: -4º to 140ºF (-20º to 60ºC)
over 1 month: -4ºF to 113ºF (-20º to 45ºC)
