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.
On alkaline batteries/Oxy Nickel
Primary Battery
• Alkaline batteries/Oxy Nickel Primary Battery
have a shorter life compared to the Nickel-Metal
Hydride batteries. For this reason, the power
may turn off even though the battery remaining
indicator shows sufficient battery life remaining.
• Battery performance differs greatly depending
on the manufacturer and the type of battery, and
in some cases the battery life may be extremely
short. This is especially true at low
temperatures, and you may not be able to shoot
at temperatures below 5°C (41°F).
• Do not mix new and old batteries.
• The battery remaining indicator may not display
the correct information when using alkaline
batteries/Oxy Nickel Primary Battery.
• Due to characteristics of alkaline batteries/Oxy
Nickel Primary Battery, there is a large
difference between the available shooting time
and the available playback time. For this reason,
the camera may turn off with the lens portion
extended when you switch the mode dial. In this
case, replace the batteries with new ones or fully
charged Nickel-Metal Hydride batteries.
