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 batteries, temperature, and how the camera and WT-3 are used. The following measurements were performed at a temperature of 20 °C (68 °F) both with the WT-3 off and while uploading photographs to a Windows XP Professional SP2 computer using Auto send.

Example 1

Network None (WT-3 off ) Wireless (802.11g, infrastructure mode) Ethernet (100 base-TX)

No. of shots 160010001100 Camera Zoom Nikkor AF-S VR 70–200 mm f/2.8G IF ED lens (VR off ); continuous high- settings speed 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 infi nity to minimum range three times with each shot; after six shots, monitor turned on for fi ve seconds and then turned off; cycle repeated after eight seconds.

Example 2

Network None (WT-3 off ) Wireless (802.11g, infrastructure mode) Ethernet (100 base-TX)

No. of shots 300200210

Camera Zoom Nikkor AF-S VR 24–120 mm f/3.5–5.6G IF ED lens (VR off ); single-frame settings 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 fi ve seconds and focus cycled from infi nity to minimum range once with each shot; built-in Speedlight fi red at full power with every other shot; AF-assist illuminator lights when Speedlight is used; cycle repeated after eight seconds; camera turned off

for one minute after ten photographs have been transferred.

The following can reduce battery life:

 

• Using the monitor

• Repeated autofocus operations

• Keeping the shutter-release button pressed

• Taking NEF (RAW) photographs

halfway

• Slow shutter speeds

To ensure maximum battery performance:

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

Use EN-EL3e batteries immediately after charging. Batteries will lose their charge if left un- used.

The battery level displayed by the camera may vary with changes in temperature.
