zThe Battery Charger CB-5AH/CB-5AHE can only be used
with Canon AA-size NiMH batteries NB-3AH and NB-2AH.
Do not attempt to charge any other types of batteries.
zDo not mix batteries with different purchase dates or different
charge states. When recharging batteries, always recharge
all 4 of them at the same time.
zDo not attempt to recharge fully charged batteries, as doing
so may reduce or impair battery performance. Also, do not
charge batteries for more than 24 consecutive hours.
z
Do not recharge batteries in enclosed areas that tend to retain
heat.
z
Repeatedly recharging batteries before they become fully
depleted may cause batteries to lose capacity. Do not recharge
the batteries until the LCD monitor (or viewfinder) displays the
"Change the batteries" message.
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 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)
zYou 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.
zSince 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 (0 - 30 °C (32 - 86 °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.
