On the battery pack
On charging the battery pack
We recommend charging the battery pack in an
ambient temperature of between 10°C to 30°C
(50°F to 86°F). You may not be able to efficiently
charge the battery pack outside of this temperature
range.
Effective use of the battery pack
• Battery performance decreases in low
temperature surroundings. So, the time that the
battery pack can be used is shorter in cold
places. We recommend the following to ensure
longer battery pack use:
– Put the battery pack in a pocket close to your
body to warm it up, and insert it in your
camera immediately before you start
shooting.
• The battery pack will run out quickly if you use
the flash or zoom frequently.
• We recommend having spare battery packs
handy for two or three times the expected
shooting time, and making trial shots before
taking the actual shots.
• Do not expose the battery pack to water. The
battery pack is not water-resistant.
• Do not leave the battery pack in extremely hot
places, such as in a car or under direct sunlight.
How to store the battery pack
• If the battery pack is not to be used for a long
time, fully charge it and then fully use it up once
a year on your camera before storing the battery
pack in a dry, cool place. Repeat this charging
and using up once a year to maintain the battery
pack’s function.
• To use the battery pack up, leave your camera in
slide show (page 52) playback mode until the
power goes off.
• To prevent staining the terminal, short-
circuiting, etc., be sure to use a supplied battery
case when carrying and storing.
On battery life
• The battery life is limited. Battery capacity
decreases little by little as you use it more and
more, and as time passes. If the battery
operating time seems shortened considerably, a
probable cause is that the battery pack has
reached the end of its life. Buy a new battery
pack.
• The battery life varies according to how it is
stored and the operating conditions and
environment in which each battery pack is used.
