Battery Life
The number of shots that can be taken with a fully-charged EN-EL3e battery (1500 mAh) varies with
the condition of the battery, temperature, and how the camera is used. The following measurements
were performed at a temperature of 20 °C (68 °F).
Example 1: 2,700 shots
AF-S DX IF ED 18–135 mm f/3.5–5.6G lens; continuous shooting mode; continuous-servo autofocus;
image quality set to JPEG Basic; image size set to M; shutter speed ⁄ s; shutter-release button pressed
halfway for three seconds and focus cycled from infi nity to minimum range three times; after six shots,
monitor turned on for fi ve seconds and then turned off ; cycle repeated once exposure meters have
turned off .
Example 2: 600 shots
AF-S DX IF ED 18–135 mm f/3.5–5.6G lens; single-frame shooting mode; continuous-servo autofocus;
image quality set to JPEG Normal; image size set to L; shutter speed 1⁄250 s; shutter-release button
pressed halfway for fi ve seconds and focus cycled from infi nity to minimum range once; monitor
turned on for four seconds after each shot; built-in Speedlight fi red at full power with every other shot;
next shot taken after exposure meters have turned off .
