“InfoLITHIUM” battery pack
Your camera operates only with an “InfoLITHIUM” battery pack NP-FW50. You cannot
use any other battery packs. “InfoLITHIUM” W series battery packs have the
mark.
An “InfoLITHIUM” battery pack is a lithium-ion battery pack that has functions for
communicating information related to operating conditions with the camera.
The “InfoLITHIUM” battery pack calculates the power consumption according to the
operating conditions of your camera, and displays the remaining battery time in
percentages.
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). The battery pack may not be effectively charged in temperatures
outside this range.
Effective use of the battery pack
• Battery performance decreases in low temperature surroundings. So in cold places, the
operational time of the battery pack is shorter. To ensure longer battery pack use, we
recommend putting the battery pack in a pocket close to your body to warm it up, and
insert it in the camera immediately before you start shooting.
• The battery pack will run out quickly if you use the flash or record movies frequently.
• We recommend having spare battery packs handy 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 indicator
When the power goes off even though the remaining battery time indicator indicates that
the battery pack has enough power to operate, charge the battery pack again. Remaining
battery time will be indicated correctly. Note, however, that the battery indication will
not be restored if it is used in high temperatures for a long time, or if left after being
charged, or when the battery pack is frequently used. Use the remaining battery
indication as a rough guide only.
How to store the battery pack
• Fully discharge the battery pack before storing and store it in a cool, dry place. To
maintain the battery pack’s function, charge the battery pack and then fully discharge
it on the camera at least once a year.
• To use the battery pack up, leave the camera in slide show playback mode until the
power goes off.
• To prevent staining the terminal, short-circuiting, etc., be sure to use a plastic bag to
keep away from metal materials when carrying or storing the battery pack.
