• The measurement method is based on the CIPA standard.
(CIPA: Camera & Imaging Products Association)
• The battery capacity decreases as the number of uses increases and also
over time.
• The number of images that can be recorded is decreased under the
following conditions:
– The surrounding temperature is low.
– The camera has been turned on and off many times.
– Focus mode is set to AF-C (Continuous AF).
– When the camera continues to focus for a long time without shooting,
including cases where you press and hold the shutter button halfway
down.
Effective use of the battery pack
Battery performance decreases in low temperature surroundings. So, the
time that the battery pack can be used is shorter in cold places. We
recommend the following to ensure longer battery pack use: put the battery
pack in a pocket close to your body to warm it up, and insert it in your
camera immediately before you start shooting.
Battery life
• The battery life is limited. Battery capacity decreases little by little as you
use it more and more, and as time passes. If the battery operating time
seems shortened considerably, a probable cause is that the battery pack
has reached the end of its life. Buy a new battery pack.
• The battery life varies according to how it is stored and the operating
conditions and environment in which each battery pack is used.
How to store the battery pack
If the battery pack is not to be used for a long time, fully charge it and then
fully use it up once a year on your camera before storing the battery pack in
a dry, cool place to prolong the battery life.
