eOo not allow any metal objects
such as key rings to touch the
(::8
and
e
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).
eEven 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.
eSince 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 OF) 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.
elf the performance of the battery pack diminishes substantially even when it
is fully charged, its life has been exceeded and it should be replaced.
