How to use
Charging
•Before use, be sure to charge the battery with the specified charger. During
charging, LEDs will light one by one in order via “Check Charging.”
•LEDs are lit until actual charging is complete (more than 90%) (They cannot
be put out partway through charging). The LEDs are not lit from actual
charging complete-fully charged. The battery will be fully charged about 1
hour after actual charging is complete.
•When charging a battery with it installed in your camcorder with a charging
lamp, the camcorder’s charging lamp will not be lit (fully charged) after
about 1 hour once the battery LED goes out (actual charging).
* Depending on the camcorder, there are models that go out at the same
time as the battery when actual charging is complete. For details, please
see the operating instruction for the camcorder you are using.
•We recommend charging the battery fully in an ambient temperature of
between 10-30°C. Effective charging cannot be performed outside this
temperature range.
P
Note
When charging the battery after it has not been used for a long period of time,
the LEDs may not light immediately after the start of charging or during
charging; this is not a malfunction.
To check the remaining battery capacity
•Indicates the remaining capacity of the battery via 4 LEDs.
•When the Check Capacity button (PUSH)
C
is pushed, LED
D
lights for
about 3 seconds.
P
Note
1. LEDs will not light when charging with an AC adaptor/charger (AC-
VQ850/SQ950 or the like) with an LCD even if
C
is pushed during
charging. Check the time remaining on the AC adaptor/charger’s LCD.
2. LEDs will not light when installing and using (including charging) the
battery in your camcorder that is “InfoLITHIUM”-capable even if
C
is
pushed during charging. Check the time remaining on your camcorder’s
LCD.
3. The level remaining as displayed by your camcorder and that in the LED
indicator may not match. Use this as a guideline.
Level remaining
•When charging in a battery charger (BC-VM50 or the like), pushing
C
will
cause the LED to light.
•When a camcorder light (HVL-20DM, HVL-IRM or the like) is in use,
pushing
C
will cause the LED to light.
Good use of the battery
•In cold places, the time that the battery can be used will decrease when the
ambient temperature is low and battery performance drops. We
recommend the following for longer worry-free use:
– Put the battery in a pocket and warm it; install it in the device that will be
used immediately before shooting.
•Actively turn off the power switch during shooting or replay. Battery
power is consumed even when in shooting standby or paused replay.
•Have spare battery handy for two or three times the expected recording
time, and make trial recording before taking the actual recording.
Battery storage
Even when the battery will not be used for a long period of time, fully charge
the battery about once a year to maintain battery functions and use it up in
the device that will be used; then, store it in a cool place with a low level of
humidity.
Battery life
•The battery life is limited. Battery capacity drops little by little as you use it
more and more, and as battery has reached the end of its life. Please buy a
new battery.
•The battery life varies according to how it is stored and operating conditions
and environment for each battery.
Warranty for Images/Recorded Contents
Compensation for images/recorded contents will not be provided in the
