Battery Pack Handling Precautions
z Keep the battery pack and camera terminals
( ) clean at all times. Dirty terminals may
cause a 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.
z Do not cover the battery charger with anything,
such as a tablecloth, cushion or blanket, when it is
charging. Heat will build up internally and possibly
lead to fire.
z Do not charge Battery other than Battery Pack NB-
2LH/NB-2L (sold separately) with the supplied
battery charger.
z The battery pack continues to discharge a small
amount when left in the camera (even with the
power turned off) or battery charger. This shortens
the battery life. Remove the battery pack when the
camera is not in use.
z 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). When using
Battery Pack NB-2LH, you can distinguish between
a discharged battery pack and fully charged battery
pack by changing the direction of the battery cover
(Fig. C and D). Recharge the battery fully before
using it again.
z 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.
z Since storing a fully charged battery pack for long
periods of time (about 1 year) can shorten its
lifecycle or affect performance, store the battery in
an indoor location with low relative humidity and
between the temperatures of 0 to 30 °C (32 to
86 °F). If you do not use the battery pack for long
periods of time, charge it fully and discharge it fully
