Additional Information
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 the battery pack
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.
With an AC adaptor/charger (optional), the remaining battery time and charging time
are 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 FULL appears in the display window, indicating that
the battery pack is fully charged. If you charge the battery pack outside of this
temperature range, you may not be able to efficiently charge the battery pack.
• 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 becomes shorter. 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 camcorder immediately before you start taking shots.
– Use the large capacity battery pack (NP-FM70/QM71/FM90/FM91/QM91,
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/FM90/FM91/QM91, 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 recording before the actual recording.
• Do not expose the battery pack to water. The battery pack is not water-resistant.
