Effective use of Nickel-Metal Hydride
batteries
• Batteries are discharged even when they are not
used. We recommend you charge the batteries
just before using 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 the poles of the batteries and the terminals on
the battery cover of the camera are dirty, the
battery life may be extremely shortened.
Occasionally wipe them with a dry cloth, etc. to
keep them clean.
• If you shoot a lot using the flash and the zoom,
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.
Battery life of Nickel-Metal Hydride
batteries
• The battery life is limited. The 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 their life.
• The battery life varies depending on storage,
operating conditions, and environment, and is
different for each battery.
