Battery Pack Handling Precautions
DANGER!
Treat the battery pack with care.
• Keep it away from fire (or it might explode).
• Do not expose the battery pack to temperature higher than 60 ºC. Do not leave
it near a heater or inside a car in hot weather.
• Do not try to disassemble or modify it.
• Do not drop or knock it.
• Do not get it wet.
❍ Charged battery packs continue to discharge naturally. Therefore, charge them on
the day of use, or the day before, to ensure a full charge.
❍ Attach the terminal cover whenever a battery pack is not in use. Contact to metallic
objects may cause a short circuit and damage the battery pack.
❍ Dirty terminals may cause a poor contact between the battery pack and the
camcorder. Wipe the terminals with a soft cloth.
❍ Since storing a charged battery pack for a long time (about 1 year) can shorten its
lifecycle or affect performance, we recommend to discharge the battery pack fully
and to store it in a dry place at temperatures no higher than 30 ˚C. If you do not
use the battery pack for long periods, charge and discharge it fully at least once a
year. If you have more than 1 battery pack, perform these precautions at the same
time for all battery packs.
❍ Although the battery pack's operating temperature range is from 0 ˚C to 40 ˚C, the
optimal range is from 10 ˚C to 30 ˚C. At cold temperatures, performance will
temporarily decline. Warm it in your pocket before use.
❍ Replace the battery pack if the usable time after full charge diminishes substantially
at normal temperatures.
