About the battery pack
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 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 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. In that case, put the battery pack in
a pocket to warm it up, and install it on your camcorder right before you start taking shots to use the
battery pack for a longer time.
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.
You may not be able to turn on the camcorder or the battery pack may not be effectively charged if
the terminal section of the battery is dirty. In this case, wipe any dust off lightly using a soft cloth or a
cotton swab to clean the battery.
About the remaining battery time indicator
When the power goes off even though the remaining battery indicator indicates that the battery pack
has enough power to operate, charge the battery pack fully again. Remaining battery indicator 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.
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.
To discharge the battery pack on your camcorder completely, select
[Setup] [
General Settings] [Power Save] [Off], and leave your camcorder in recording standby until
the power goes off. [Details]
To prevent staining the terminal, short-circuiting, etc., be sure to use a supplied battery case when
carrying or storing.
About battery life
Battery capacity decreases over time and through repeated use. If decreased usage time between
charges becomes significant, it is probably time to replace it with a new one.
Each battery’s life is governed by storage, operating and environmental conditions.
