Nokia 311 - Manual (Page 100)

Always keep the battery between
15°C and 25°C (59°F and 77°F).
Extreme temperatures reduce the
capacity and lifetime of the battery. A
device with a hot or cold battery may
not work temporarily.
Accidental short-circuiting can
happen when a metallic object
touches the metal strips on the
battery, for example, if you carry a
spare battery in your pocket. Short-
circuiting may damage the battery or
the connecting object.
Do not dispose of batteries in a fire as
they may explode. Dispose of
batteries according to local
regulations. Recycle when possible.
Do not dispose as household waste.
Do not dismantle, cut, open, crush,
bend, puncture, or shred cells or
batteries. If a battery leaks, do not let
battery liquid touch skin or eyes. If
this happens, immediately flush the
affected areas with water, or seek
medical help.
Do not modify, remanufacture,
attempt to insert foreign objects into
the battery, or immerse or expose it
to water or other liquids. Batteries
may explode if damaged.
Use the battery and charger for their
intended purposes only. Improper
use, or use of unapproved batteries or
incompatible chargers may present a
risk of fire, explosion, or other hazard,
and may invalidate any approval or
warranty. If you believe the battery or
charger is damaged, take it to a
service centre for inspection before
continuing to use it. Never use a
damaged battery or charger. Only use
the charger indoors.
