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 your camcorder or 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 FULL appears in the display window, indicating that
the battery pack is fully charged. If you charge the battery outside of this temperature
range, you may not be able to efficiently charge the battery pack.
• After charging is completed, either disconnect the AC power adaptor 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
use the battery pack longer:
– 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/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.
• Have spare battery packs handy for two or three times the expected recording time,
and make 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 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.
