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-
FM50/FM70/QM71/QM71D/FM91/
QM91/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-FM50/FM70/QM71/QM71D/
FM91/QM91/QM91D (optional).
• Be sure to set the POWER switch to (CHG)
OFF 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 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
E
even if there are still 5 to 10 minutes of battery
time remaining, depending on the operating
conditions or ambient temperature and
environment.

Additional Information
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 on your
camcorder once a year to maintain the proper
function.
To store the battery pack, remove it from your
camcorder and put it in a dry, cool place.
• To discharge the battery pack on your
camcorder completely, set [A.SHUT OFF] to
[NEVER] on the
menu and leave your camcorder in tape
recording standby until the power goes off
(p. 81).
About 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 depending on how it is
stored and the operating conditions and
environment for each battery pack.
