Nokia 9110 User Manual page 29

Note
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged or worn out.
Do not short-circuit the battery. Accidental short-circuiting can occur when a
metallic object (coin, clip or pen) causes direct connection of the + and -
terminals of the battery (metal strips at the bottom of the battery), for
example, when you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in summer or
winter conditions, will reduce the capacity and lifetime of the battery. Always
try to keep the battery between +15°C (+59°F) and +25°C (+77°F). A
communicator with a hot or cold battery may temporarily not work, even
when the battery is fully charged. The performance of Lithium-ion batteries is
particularly limited in temperatures below 0°C (+32°F).
Do not dispose of batteries in a fire!
Batteries must be recycled or disposed of properly. Batteries must not
be disposed of in municipal waste.
