Appendix
Battery Pack
This camcorder uses a lithium-ion type
battery pack.
Charging
• Charge the battery pack immediately (or a
day) before use. The battery pack gradually
self-discharges even if stored in a fully
charged state.
• Charge the battery pack between 50°F and
86°F (10°C and 30°C).
• Fully charge the battery pack. Use of an
insufficiently charged battery pack will
shorten actual time of use.
• Refresh (discharging before charging) is
unnecessary.
Use
• To conserve battery power, be sure to turn off
the camcorder power when not in use.
• Battery consumption may vary depending on
the condition of use. Recording with many
starts and stops, frequent zooming, and
recording in low temperatures will shorten
actual recording times.
• Use of a weak battery pack may cause loss
of power while operating the camcorder. Use
a fully charged battery pack to protect both
the battery pack and the unit.
• It is recommended that you have enough
battery packs on hand to handle two or three
times your estimated recording time. See
page 20 for the approximate times of actual
recording for the battery packs.
Battery power is consumed even when the
camcorder power is turned off. If you are not
going to use your camcorder immediately,
remove the battery pack (see page 10).
Note:
• Use only SHARP BT-L221 or BT-L441 battery
packs. These are designed specifically for use
with this camcorder.
Storage
• Store the battery pack in a fully discharged
state.
• Store the battery pack in a dry, cool place.
• When storing a fully charged battery pack,
put the cover on it so that the “CHARGE”
mark printed on the label is seen through the
window, as shown.
When storing a battery pack that is not fully
charged, put the cover upside down so that
only the battery pack casing can be seen
through the window.
Cautions:
• Improper handling of the battery pack may
present a risk of fire or explosion. Pay close
attention to the following:
— Do not allow metallic objects to come in
contact with the terminals. This can cause a
short circuit.
— Do not disassemble or repair the battery pack
by yourself.
— Do not use any battery charging equipment
other than that designed for use with these
battery packs.
— Do not place the battery pack under direct
sunlight or in excessively hot places (over
140°F or 60°C) such as the dashboard of
cars.
— Do not expose the battery pack to moisture or
water.
— Do not drop the battery pack or subject it to
strong force.
— Keep the battery pack out of reach of
children.
— Dispose of used battery packs promptly. Do
not dispose of them in fire.
• To protect the terminals, put the cover on the
battery pack when it is not being used.

Notes:
• The battery pack will become warm during
charging and use. This is not a malfunction.
• The battery pack has a limited service life. If the
period of use becomes noticeably shorter with a
normal charge, the battery pack is at the end of
its service life. Replace it with a new battery
pack.
• If the terminals of the battery pack are dirty, wipe
the terminals with a soft, dry cloth.
