Appendix
- If the battery usage time has
considerably diminished
- If the number of recordable images has
considerably diminished
- When charging the batteries (insert and
remove the batteries two or three times
before charging)
- When charging completes in a matter of
a few minutes (the battery charger
indicator remains lit)
z You may not be able to fully charge the
batteries due to their specifications right
after purchase or after long periods of
non-use. If this happens, use the
batteries until their charge is depleted
before charging them again. After doing
this several times, battery performance
will be restored.
z Since storing fully charged batteries for
long periods of time (about 1 year) can
shorten their lifecycle or affect
performance, you are recommended to
use the batteries in the camera until they
are completely discharged and to store
them at normal temperature (23 °C/73 °F)
or less. If you do not use the batteries for
long periods of time, charge them fully
and discharge them fully in the camera at
least once a year before returning them
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’s AA-size NiMH batteries (four
piece set).
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 250 minutes for
the charger to fully recharge the
batteries (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
95°F).
