On the “InfoLITHIUM” battery pack
This camera requires an “InfoLITHIUM” 
battery pack (T type).
What is an “InfoLITHIUM” battery 
An “InfoLITHIUM” battery pack is a 
lithium-ion battery pack that has functions 
for exchanging information related to 
operating conditions with 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 
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 
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 
• 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.
On the remaining battery time 
The power may go off although the battery 
remaining indicator shows there is enough power 
to operate. Use the battery pack up and charge the 
battery pack fully again so that the indication on 
the battery remaining indicator is correct. Note, 
however, that the correct battery indication 
sometimes will not be restored if the battery pack 
is used in high temperatures for a long time, left in 
a fully charged state or used frequently.
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 27) 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 
• The battery life varies according to how it is 
stored and the operating conditions and 
environment in which each battery pack is used.
