Battery Life

The number of shots that can be taken with a fully-charged EN-EL3a battery (1500 mAh) varies with the condition of the batteries, temperature, and how the camera is used. The following measurements were performed at a temperature of 20 °C (68 °F).

Example 1: 2500 shots

Zoom Nikkor AF-S DX 18–70 mm f/3.5–4.5G IF ED lens; continuous shooting mode; continuous-servo autofocus; image quality set to JPEG Basic; image size set to M; shutter speed ½50 s; shutter-release pressed halfway for three seconds and focus cycled from infinity to minimum range three times with each shot; after six shots, monitor turned on for five seconds and then turned off; cycle repeated once exposure meters have turned off.

Example 2: 500 shots

AF-S DX 18–70 mm f/3.5–4.5G IF ED lens; single-frame shooting mode; single-servo autofocus; image quality set to JPEG Normal; image size set to L; shutter speed ½50 s; shutter-release pressed halfway for five seconds and focus cycled from infinity to min- imum range once with each shot; built-in Speedlight fired at full power with every other shot; AF-assist illuminator lights when Speedlight is used; cycle repeated once exposure meters have turned off; camera turned off for one minute with every ten shots.

The following can reduce battery life:

 

• Using the monitor

• Repeated autofocus operations

• Keeping the shutter-release button

• Taking NEF (RAW) photographs

pressed halfway

• Slow shutter speeds

To ensure maximum battery performance:

Keep the battery contacts clean. Soiled contacts can reduce battery performance.

Use EN-EL3a batteries immediately after charging. Batteries will lose their charge if left unused.
