Maximizing Camera Life and Performance
Caring for the Camera
C The Battery
• Check the battery level before using the camera and replace or charge the battery if necessary. Do
not continue charging once the battery is fully charged as this will result in reduced battery
performance. Whenever 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.
• When charging the battery inserted into the COOLPIX S4100 using the Charging AC adapter
EH-69P or a computer, the battery is not charged at battery temperatures below 0°C (32°F) or
above 45°C (113°F).
• Note that the battery may become hot during use; wait for the battery to cool before charging.
Failure to observe these precautions could damage the battery, impair its performance, or prevent
it from charging normally.
• On cold days, the capacity of batteries tends to decrease. Be sure that the battery is fully charged
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 may recover some of its charge.
• Dirt on the battery terminals can prevent the camera from functioning. Should the battery
terminals become dirty, wipe them 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. The battery should be stored in a cool location with an ambient temperature of 15°C
to 25°C (59°F to 77°F). Do not store the battery in hot or extremely cold locations.
• Always remove the battery from the camera or optional battery charger when it is not being used.
When inserted, minute amounts of current are drawn from the battery even when not in use. This
may result in excessive draining of the battery and complete loss of function. Turning the camera
on or off while the battery is exhausted can result in reduced battery life.
• Recharge the battery at least once every six months and completely exhaust it before returning it
to storage.
• After removing the battery from the camera or optional battery charger, return the battery to the
battery case and store in a cool place.
• 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 EN-EL19 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.
