Proper Battery Handling
¡
Use AA-size alkaline or Canon AA-siz e NiMH batteries only.
For information on handling the AA-siz e rechargeable NiMH
batteries, see “Using the Optional Batter y Kits” (p. 144).
¡
Never use manganese or lithium batter ies, as these battery
types may overheat in the camera.
¡
Since the performance of alkaline batteries may differ
according to brand, the operating time of the batter ies you
purchase may not be as long as the batteries that came with
the camera.
¡
Camera operating time may shorten at low temperatures when
alkaline batteries are used. Also due to their specifications,
alkaline batteries may expire faster than NiMH batter ies. If you
are using the camera in cold areas or for a long time, we
recommend using Canon AA-size NiMH Battery Kit (a four-
piece set).

While it is possible to use AA-size nickel-cadmium batteries,
performance is unreliable and their use is not recommended.
