The following can reduce battery life:
• Using the monitor
• Keeping the shutter-release button pressed halfway
• Repeated autofocus operations
• Taking NEF (RAW) or TIFF (RGB) photographs
• Slow shutter speeds
• Using optional WT-2/2A or WT-1 / 1A wireless transmitters
To ensure that you get the most from rechargeable Nikon EN-EL4a batteries:
• Keep the battery contacts clean. Soiled contacts can reduce battery performance.
• Use batteries immediately after charging. Batteries will lose their charge if left un-
used.
