Battery Life
The number of shots that can be taken with a fully-charged EN-EL3e battery (1500 mAh) varies
with the con di tion 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)

The following can reduce battery life:
• Using the monitor
• Keeping the shutter-release button pressed
halfway
• Repeated autofocus operations
• Taking NEF (RAW) photographs
• 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.
