7.2 Safety
7.2.1 Battery Pack/Memory Backup Battery
Battery Pack
• Never disassemble or retrofit the battery pack. The battery pack has safety mechanism and
protection means incorporated to avoid hazards. Should they be damaged, the battery pack
could become hot, generate smoke, explode, or ignite.
• Never contact the “+” and “-“ terminals with a metal object such as wire. Also, do not carry or
store the battery with a metal case. Otherwise, the battery pack may be short-circuited resulting
in an excessive current and causing the battery pack to become hot, smoke, explode, or catch
fire.
• Neither dispose of the battery pack into a fire nor heat it. The insulation may be burnt, the gas
exhaust valve or safety mechanism may be damaged, or the internal electrolyte may ignite,
causing the battery pack to become hot, smoke, explode, or ignite.
• Neither leave nor use the battery pack in a place with a high temperature (over 80°C) or close
to a fire or hot stove. Should the resin separator be damaged due to excessive heat, the battery
pack may be short-circuited causing it to become heated, smoke, explode, or ignite.
• Do not soak the battery pack in fresh water or sea water. If the protection means incorporated in
the battery pack are damaged, the battery pack may become hot, smoke, explode, or ignite.
• Do not attempt to charge the battery pack close to a fire, in direct sunlight, or in a car parked in
the sun. A heated battery pack will trigger the internal hazard protection means to stop the
charging function. Or, the protection means may be damaged and the battery may be charged
with an excessive current or voltage, or have abnormal chemical reactions induced to cause it to
become hot, smoke, explode, or ignite.
• Do not stick a pin or nail in the battery pack. Neither hit it with a hammer nor stamp on it. If
this is done, the battery pack may be broken or deformed resulting in a short circuit and causing
it to become hot, smoke, explode, or ignite.
• Do not hit or throw the battery pack. If the protection means incorporated in the battery pack
are damaged, the battery pack may be charged with an excessive current or voltage, or have
abnormal chemical reactions induced to cause it to become hot, smoke, explode, or ignite.
• Never use a battery pack that is significantly damaged or deformed. It may become hot, smoke,
explosion, or ignite.
• Do not attempt to solder anything directly on the battery pack surface. The insulation may be
damaged or the gas exhaust valve or safety mechanism may be damaged, causing the battery
pack to become hot, smoke, explode, or ignite.
• Do not use the battery pack in other devices than the specified products by CASIO. The
performance or service life of it may be reduced or abnormal current may flow to cause it to
become hot, smoke, explode, or ignite.
• When charging the battery pack with battery charger or cradle use only the dedicated AC
adaptor supplied from CASIO, at a temperature between 0°C and 40°C. If the battery pack is
charged with chargers or cradles other than those specified by CASIO, it may be over-charged,
or charged with an excessive current, or have abnormal chemical reactions induced, causing it
to become hot, smoke, explode, or ignite.
