Battery Capacity
The actual figures will vary according to the shooting conditions and 
Movie data is excluded.
At low temperatures, the battery performance may diminish and the 
low battery icon (blinking red) may appear very rapidly. In these 
circumstances, the performance can be improved by warming the 
battery in a pocket before use.
