Technical Notes and Index
The Battery
• Be sure to read and follow the warnings of “For Your Safety” (Aix-xii) thoroughly before
using 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).
• When the battery temperature is between 0°C and 10°C (32°F–50°F) or 45°C–60°C
(113°F–140°F), the chargeable capacity may decrease.
• The battery is not charged at ambient temperatures below 0°C (32°F) or above 60°C
(140°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–25°C (59°F–77°F). Do not store the battery in hot or extremely cold
locations.
• Always remove the battery from the camera or 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. When the battery level is low, be sure to charge the battery before using it.
• 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 battery charger, attach the included
terminal cover to the battery and store it in a cool place.
