About 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 between your camcorder
and an AC Adaptor/charger (optional).
The “InfoLITHIUM” battery pack calculates the power consumption according to the
operating conditions of your camcorder, and displays the remaining battery time in
minutes. Estimated operating time and charging completion time are also displayed.
Charging the battery pack
•Be sure to charge the battery pack before you start using your camcorder.
•We recommend charging the battery pack in an ambient temperature of between 10°C
to 30°C (50°F to 86°F) until the charge lamp goes off. If you charge the battery outside
of this temperature range, you may not be able to efficiently charge the battery.
•After charging is completed, either disconnect the cable from the DC IN jack on your
camcorder or remove the battery pack.
Effective use of the battery pack
•Battery pack 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 to warm it up, and insert it in your camcorder
immediately before you start taking shots.
– Use the large-capacity battery pack (NP-FM70/QM71/QM71D/FM90/FM91/
QM91/QM91D, optional).
•Frequently using the LCD panel or frequently operating playback, fast-forward or
rewind wears out the battery pack faster. We recommend using the large-capacity
battery pack (NP-FM70/QM71/QM71D/FM90/FM91/QM91/QM91D, optional).
•Be sure to turn the POWER switch to OFF (CHG) when not taking shots or playing
back on your camcorder. The battery pack is also consumed when your camcorder is
in the standby mode or playback is paused.
•Have spare battery packs handy for two or three times the expected recording time,
and make a trial recordings before taking the actual recording.
•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 remaining battery time indicator indicates that the
battery pack has enough power to operate, charge the battery pack fully again so that
the indication on the remaining battery time 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. Regard the remaining battery time indication as the approximate
shooting time.
•The E mark indicating that there is little remaining battery time sometimes flashes
depending on the operating conditions or ambient temperature and environment even
if the remaining battery time is about five to 10 minutes.
