z Do not allow any metal objects such as key rings to touch the
(
) and ( ) 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).
z You are recommended to use it in the camera until it is
depleted 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
in the camera about once a year before returning it to storage.
z
Since this is a lithium-ion battery, you need not deplete it
before recharging.
z You are advised to charge the battery on the day of use, or one
day before, to ensure a full charge.
Even charged batteries continue to discharge naturally.
