The Battery
•
Check the battery level when taking the camera out, and charge the battery if necessary. Do not
continue charging once the battery is fully charged, as this will result in reduced battery
performance. If possible, carry a fully-charged spare battery when taking pictures on important
occasions.
•
Do not use the battery at ambient temperatures below 0 °C (32 °F) or above 40 °C (104 °F). Failure
to observe this precaution could damage the battery or impair its performance.
•
Charge the battery in an indoor environment that is between 5 and 35 °C (41 to 95 °F).
•
When charging the battery by connecting the COOLPIX S640 to the Charging AC Adapter EH-68P/
EH-68P (AR) or to a computer, the chargeable capacity may decrease when the battery
temperature is between 45 to 60 °C (113 to 140 °F). The battery will not charge if its temperature is
below 0 °C (32 °F) or above 60 °C (140 °F).
•
If an exhausted battery is used at a low temperature, the camera may not turn on. Be sure that the
battery is fully charged and spare batteries are prepared before heading outside to take pictures in
cold weather. Keep spare batteries in a warm place and exchange as necessary. Once warmed, a
cold battery that could not be used temporarily due to lowered performance may recover some of
its charge.
•
Should the battery terminals become dirty, the camera may not turn on due to poor contact. Wipe
the terminals off with a clean, dry cloth before use.
•
If the battery will not be used for some time, insert it in the camera and run it flat before removing
it for storage. Attach the included terminal cover to the battery and store it in a cool location with
an ambient temperature of 15 to 25 °C (59 to 77 °F). Do not store the battery in hot or extremely
cold locations.
•
While the battery is in storage, charge it at least once every six months and then use the camera to
run it flat again before storing it in a cool location.
•
Always remove the battery from the camera or battery charger when it is not being used. Left
installed, minute amounts of current flow even when unused, and the battery may become
excessively drained and no longer function.
•
A marked drop in the time a fully-charged battery retains its charge, when used at room
temperature, indicates that the battery needs to be replaced. Purchase a new battery.
•
Replace the battery when it no longer holds a charge. Used batteries are a valuable resource.
Please recycle used batteries in accordance with local regulations.
