On Nickel Metal Hydride batteries
Effective use of the battery
• We recommend that you use batteries until they are 
completely drained before charging them.
• Battery performance decreases in low-temperature 
surroundings, and the battery life is shortened under 
such circumstances. To use the battery longer, we 
recommend you keep the battery in its case in a 
pocket close to your body to warm it, and insert it in 
your camera just before you start shooting. 
• If you use the LCD screen with [LCD LIGHT] to 
[ON], the battery power will be used up faster.
• We recommend having spare batteries handy for two 
or three times the expected shooting time, and try test 
shooting before actually using the camera. 
• Do not expose the battery to water. The battery is not 
water-resistant. 
Battery life
• The battery life is limited. Battery capacity decreases 
little by little as you use it more and more, and as time 
passes. When the battery operating time seems to 
have been considerably shortened, a probable cause 
is that the batteries have reached the end of its life. 
• The battery life varies depending on storage, 
operating conditions, and environment, and is 
different for each battery.
