The "InfoLITHIUM"
battery pack
What is the "InfoLITHIUM"
battery pack?
The "InfoLITHIUM" battery pack is a
lithium-ion battery pack that has functions
for communicating information related to
operating conditions of your camera.

The "InfoLITHIUM" battery pack

calculates the power consumption
according to the operating conditions of
your camera, and displays the remaining
battery time in minutes.
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). If you
charge the battery pack outside of this
temperature range, you may not be able to
efficiently charge the battery pack.

Effective use of the battery pack
• Battery performance decreases in low-
temperature surroundings, and the battery
life is shortened under such
circumstances. To use the battery pack
longer, we recommend you keep the
battery pack 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 or shoot a lot
using the flash, 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 pack to water.
The battery pack is not water-resistant.
Remaining battery time indicator
If the power goes off although the battery
remaining indicator indicates that the
battery pack has enough power to operate,
charge the battery pack fully again after
running it down so that the indication on the
battery remaining indicator is correct. Note,
however, that the correct battery indication
sometimes will not be restored if it is used
in high temperatures for a long time or left
in a fully charged state, or the battery pack
is frequently used.
How to store the battery pack
• If the battery pack is not to be used for a
long time, do the following procedure
once per year to maintain proper function.
1. Fully charge the battery.
2. Discharge on your camera.
3. Remove the battery from your camera
and store it in a dry, cool place.
• To use the battery pack up on your
camera, leave the POWER button to on in
slide show playback mode (page 55) until
the power goes off.
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 battery pack has
reached the end of its life.
• The battery life varies depending on
storage, operating conditions, and
environment, and is different for each
battery pack.
