Battery Pack Handling Precautions
zKeep 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.
zDo not rapidly overturn or wave the battery charger around when it
contains the battery pack. The battery pack could fly out.
zAt 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.
zDo 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.
zDo not charge batteries other than Battery Pack NB-3L in this charger.
zThe 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.
zDo not allow any metal objects
such as key rings 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).
zEven 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.
zSince storing a fully charged battery pack for long periods of time (about
one year) may shorten its life cycle or affect its performance, you are
recommended to use it in the camera until it is completely discharged and
to store it in a cool place at room temperature (0 °C to 30 °C). If you do not
use the battery pack for long periods of time, charge it fully and discharge it
fully in the camera about once a year before returning it to storage.
zIf the performance of the battery pack diminishes substantially even when it
is fully charged, its life has been exceeded and it should be replaced.
