Nokia 232N Owner's Manual page 58

Temperature extremes will affect the ability of
your battery to charge: it may require cooling or
warming first.
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 on
the back 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 and
25° C (59° F and 77° F). A phone with a hot or cold
battery may temporarily not work, even when
the battery is fully charged. NiMH batteries
performance is particularly limited in temperatures
below -10°C (14° F).
Dispose of used batteries in accordance with local
regulations. Recycle! Do not dispose of batteries
in a fire!
