About the “InfoLITHIUM” battery pack
Your camcorder operates only with an “InfoLITHIUM” V series battery packs.
“InfoLITHIUM” V 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 AC Adaptor/charger
(sold separately).
The “InfoLITHIUM” battery pack calculates the power consumption according to the operating
conditions of your camcorder, and displays the remaining battery capacity in minutes.

To charge the battery pack

Be sure to charge the battery pack before you start using your camcorder.
We recommend that you charge the battery pack in an ambient temperature range of 10 ˚C to 30 ˚C
(50 °F to 86 °F) until the POWER/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.
The POWER/CHG (charge) lamp flashes during charging under the following conditions.
The battery pack is not attached correctly.
The battery pack is damaged.
The temperature of the battery pack is low.
Remove the battery pack from your camcorder and put it in a warm place.
The temperature of the battery pack is high.
Remove the battery pack from your camcorder and put it in a cool place.

To use the battery pack effectively

Battery pack performance decreases when the ambient temperature is 10 ˚C (50 °F) or below, and
the length of time you can use the battery pack becomes shorter. If that happens, one of the following
is recommended to enable longer use of the battery pack:
Put the battery pack in a pocket to warm it up, and install it on your camcorder immediately before
you start shooting.
Use a large capacity battery pack: NP-FV70/NP -FV100 (sold separately).
Frequent use of the LCD screen or a frequent playback, fast forward or reverse operation wears out
the battery pack faster.
Be sure to close the LCD screen 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 2 or 3 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. 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 rough guide only.
Depending on the operating conditions or ambient temperature, the icon that indicates a low
battery may flash even if there are still 20 minutes of power remaining.
