To ensure that the camera functions as expected when the optional MB-D18 multi-power battery pack is used with AA batteries, match the option selected in this menu to the type of batteries inserted in the battery pack.
Using AA Batteries
The capacity of AA batteries drops sharply at temperatures below 20 °C (68 °F) and varies with make and storage conditions; in some cases, batteries may cease to function before their expiry date. Some AA batteries cannot be used; due to their performance characteristics and limited capacity, alkaline batteries have less capacity than some other types and should only be used if no alternative is available and then only at warmer temperatures. The camera shows the level of AA batteries as follows:
| Control panel | Viewfinder | Description |
|---|---|---|
| L | — | Batteries fully charged. |
| H | d | Low battery. Ready fresh batteries. |
|
H (flashes) |
d (flashes) |
Shutter release disabled. Change batteries. |
