• Keep the battery terminals clean at all times.
Dirty terminals may cause poor contact between the battery and
camera. Polish the terminals with a soft cotton swab before charging
or using the battery.
• At low temperatures, battery performance may be reduced and
the low battery icon (_'1) may appear earlier than usual.
Under these conditions, revive the battery 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 ring, etc.
The battery may short circuit.
• Do not allow any metal objects such as key rings to touch the
((_) and (0) terminals (Fig. A). To carry the battery or store it
during periods of disuse, always replace the terminal cover
(Fig.B).
These conditions can damage the battery. You may be able to check
the charge state depending upon how the terminal cover is attached
(Fig. C, D).

• You are recommended to use it in the camera until it is
completely discharged and to store it in an indoor location with
low relative humidity and between the temperatures of 0 -
30 °C (32 - 86 °F).
Storing a fully charged battery for long periods of time (about one
year) may shorten its life cycle or affect its performance. If you do not
use the battery for long periods of time, charge it fully and discharge it
fully in the camera about once a year before returning it to storage.
