How to store the battery pack
To maintain the battery pack’s function, charge the battery pack and then fully discharge it
in the product at least once a year before storing it. Remove the battery pack from the
camera and store the battery in a cool, dry place.
To use the battery pack up, leave the product in slide show playback mode until the
power goes off.
To prevent staining the terminal, short-circuiting, etc., be sure to use a plastic bag to keep
away from metal materials when carrying or storing the battery pack.
On battery life
The battery life is limited. If you use the same battery repeatedly, or use the same battery
for a long period, the battery capacity decreases gradually. If the available time of the
battery is shortened significantly, it is probably time to replace the battery pack with a new
one.
The battery life varies according to how the battery pack is stored and the operating
conditions and environment in which each battery pack is used.
