Appendix
z Since storing a fully charged battery for
long periods of time (about one year)
can shorten its lifecycle or affect
performance, you are recommended to
use the battery in the camera until it is
completely discharged and to store it at
normal temperature (23 °C/73 °F or
less). If you do not use the battery 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.
z If battery usage time is considerably low
despite their terminals' being wiped and
the battery charger's indicator remaining
lit, it is possible that the batteries have
reached the end of their lifespan. Switch
to different, unused batteries. If you are
purchasing new batteries, look for
Canon AA-size NiMH batteries.
z Leaving batteries in the camera or
charger may damage it causing battery
leakage. Remove batteries from the
camera or charger and store in a dry
cool location when not in use.
z It takes approximately 110 minutes when
two batteries are loaded one at each
end of the charger and 250 minutes with
four for the charger to fully recharge
them (as determined by testing at Canon
facilities). Please do not charge batteries
in areas where the temperature is
outside the range of 0 to 35 °C (32 to
104 °F).
z Charging time varies according to
ambient temperature and to the
batteries' initial charge state.
z The battery charger may emit noise
while charging. This is not a malfunction.
z You can also use Battery/Charger Kit
CBK100. For Battery/Charger Kit
CBK100, use Canon AA-size NiMH
batteries NB-1AH.
