The number of times the shutter has been released with the 
current battery since the battery was last charged. Note that 
the camera may sometimes release the shutter without 
recording a photograph, for example when measuring preset 
white balance.
Calibration
j: Due to repeated use and recharging, calibration is 
required to ensure that battery level can be measured 
accurately; recalibrate battery before charging (
0 417).

Battery 
age
A five-level display showing battery age. 0 (
k) indicates that 
battery performance is unimpaired, 4 (
l) that the battery has 
reached the end of its charging life and should be replaced. 
Note that fresh batteries charged at temperatures under 
about 5 °C (41 °F) may show a temporary drop in charging life; 
the battery age display will however return to normal once 
the battery has been recharged at a temperature of about 
20 °C (68 °F) or higher.
