Handling Precautions
• Keep the battery pack terminals ( ) clean at all times. Dirty
terminals may cause poor contact between the battery pack and
camera. Polish the terminals with a tissue or a dry cloth before charging
or using the battery pack.
• Do not rapidly overturn or wave the battery charger around when it
contains the battery pack. The battery pack could fly out.
• At low temperatures, battery pack performance may be reduced and the
low battery icon may appear earlier than usual. Under these conditions,
resuscitate the battery pack by warming it in a pocket immediately
before use. However, ensure that there are no metallic items in the
pocket that could cause a short circuit, such as a key holder, etc.
• Do not place anything, such as tablecloths, carpets, bedding or cushions,
on top of the battery charger while it is charging. Heat will build up and
could result in a fire.
• Do not charge batteries other than Battery Pack NB-1LH or NB-1L (sold
separately) in this charger.
• The battery pack continues to discharge a minimal portion of its power
while installed in the camera, even with the power off, or in the charger.
This will shorten battery life.
• Do not allow any metal objects such as keyrings to touch the “+” and “-”
terminals (Fig. A), as this can damage the battery pack. To carry the
battery pack or store it during
periods of disuse, always
replace the terminal cover
(Fig.B) or place it in the
supplied case and store it in a
cool, dry place. Recharge it
fully before using it again.
Even charged battery packs continue to discharge naturally. You are
advised to charge the battery on the day of use, or one day before,
to ensure a full charge.
Since storing a fully charged battery pack for long periods of time
(about 1 year) can shorten its life cycle or affect performance, you are
recommended to use the battery pack in the camera until it is
completely discharged and to store it at normal temperature (23°C/
73°F) or lower. If you do not use the battery pack for long periods of
time, charge it fully and discharge it fully in the camera at least once
a year before returning it to storage.
• If the performance of the battery pack diminishes substantially even when
it is fully charged, its life has been exceeded and it should be replaced.
