Appendix
z Wipe the battery terminals well with a dry
cloth in the following situations, as the
terminals may be soiled with oil from one’s
skin or other dirt:
- 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 (0 to 30°C/32 to 90°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.
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.
