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 power adaptor.
The “InfoLITHIUM” battery pack calculates the power consumption according to the
operating conditions of your camcorder, and displays the remaining battery time in
minutes.
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 backlight of the display window goes out,
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 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 use
the battery pack longer:
– 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/FM90/FM91, 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/FM90/FM91, optional).
• Be certain 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-registant.
Remaining battery time indicator
•If the power may go 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 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 ten minutes.
How to store the battery pack
•Even if the battery pack is not used for a long time, store it in a dry, cool place after
fully charging it once per year and then using the battery pack up on your camcorder.
This is to maintain the battery pack’s functions.
•To use the battery pack up on your camcorder, leave your camcorder in the shooting
mode until the power goes off without a cassette inserted.
Battery life
•The battery life is limited. Battery capacity drops little by little as you use it more and
more, and as time passes. When the available battery time is shortened considerably, a
probable cause is that the battery pack has reached the end of its life. Please buy a new
battery pack.
•The battery life varies according to how it is stored and operating conditions and
environment for each battery pack.
