its capacity.
After recharging the battery, detach it and disconnect the 
charger from the power outlet.
When not using the camera, remove the battery.
If the battery is left in the camera for a prolonged period, a small 
amount of power current is released, resulting in excess discharge 
and shorter battery life. Store the battery with the protective cover 
(provided) attached. Storing the battery when it is fully charged may 
lower the battery’s performance.
The battery charger can also be used in foreign countries.
The battery charger is compatible with a 100 V AC to 240 V AC 50/
60 Hz power source. If necessary, attach a commercially-available 
plug adapter for the respective country or region. Do not attach any 
portable voltage transformer to the battery charger. Doing so can 
damage the battery charger.
If the battery becomes exhausted quickly even after being fully 
charged, the battery has reached the end of its service life.
Purchase a new battery.
