On Nickel Metal Hydride batteries
Effective use of the battery
• We recommend that you use batteries until they are
completely drained before charging them.
• Battery performance decreases in low-temperature
surroundings, and the battery life is shortened under
such circumstances. To use the battery longer, we
recommend you keep the battery in its case in a
pocket close to your body to warm it, and insert it in
your camera just before you start shooting.
• If you use the LCD screen with [LCD LIGHT] to
[ON], the battery power will be used up faster.
• We recommend having spare batteries handy for two
or three times the expected shooting time, and try test
shooting before actually using the camera.
• Do not expose the battery to water. The battery is not
water-resistant.
Battery life
• The battery life is limited. Battery capacity decreases
little by little as you use it more and more, and as time
passes. When the battery operating time seems to
have been considerably shortened, a probable cause
is that the batteries have reached the end of its life.
• The battery life varies depending on storage,
operating conditions, and environment, and is
different for each battery.
