About the
“InfoLITHIUM” battery
pack
This unit is compatible with an
“InfoLITHIUM” battery pack (M series).
Your camcorder operates only with an
“InfoLITHIUM” battery pack.
“InfoLITHIUM” M series battery packs
have the
mark.
What is an “InfoLITHIUM” battery
pack?
An “InfoLITHIUM” battery pack is a
lithium-ion battery pack that has functions
for communicating information related
to operating conditions between your
camcorder and an optional AC Adaptor/
charger.
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 appear.
To charge 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 CHG (charge) lamp
turns off. If you charge the battery pack outside
of this temperature range, you may not be able
to charge it efficiently.
• After charging is complete, disconnect the cable
from the DC IN jack on your camcorder or
remove the battery pack.
To use the battery pack effectively
• Battery pack performance decreases when the
surrounding temperature is 10°C (50 °F) or
below, and the length of time you can use the
battery pack becomes shorter. In that case, do
one of the following to use the battery pack for
a longer time.
– Put the battery pack in a pocket to warm it up,
and insert it in your camcorder right before
you start taking shots.
– Use a large capacity battery pack: NP-
QM71D/QM91D (optional).
• Frequent use of the LCD screen or a frequent
playback, fast forward or rewind operation
wears out the battery pack faster.
We recommend using a large capacity battery
pack: NP-QM71D/QM91D (optional).
• Be sure to set the POWER switch to OFF
(CHG) when not recording or playing back
on your camcorder. The battery pack is also
consumed when your camcorder is in recording
standby or playback pause.
• Have spare battery packs ready for two or
three times the expected recording time, and
make trial recordings before making the actual
recording.
• Do not expose the battery pack to water. The
battery pack is not water resistant.
About 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 fully again.
The indication on the 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 in a fully charged state, or when
the battery pack is frequently used. Use the
remaining battery time indication as a guide to
the approximate shooting time.
• The  mark that indicates low battery flashes
even if there are still 5 to 10 minutes of battery
time remaining, depending on the operating
conditions or ambient temperature and
environment.
About storage of the battery pack
• If the battery pack is not used for a long time,
fully charge the battery pack and use it up on
your camcorder once a year to maintain proper
function. To store the battery pack, remove it
from your camcorder and put it in a dry, cool
place.
