238 Technical Notes
The approximate length of footage or number of shots that can be
recorded with a fully-charged EN-EL15b
1
battery varies with the monitor
mode. The figures for photographs
2
are as follows:
• Viewfinder only: 330 shots (Z 7), 310 shots (Z 6)
• Monitor only: 400 shots (Z 7), 380 shots (Z 6)
The figures for movies
3
are:
• Viewfinder only: 85 minutes
• Monitor only: 85 minutes
Actions such as the following can reduce battery endurance:
• Keeping the shutter-release button pressed halfway
• Repeated autofocus operations
• Taking NEF (RAW) photographs
• Slow shutter speeds
• Using camera Wi-Fi (wireless LAN) and Bluetooth features
• Using the camera with optional accessories connected
• Repeatedly zooming in and out
To ensure that you get the most from rechargeable Nikon EN-EL15b
batteries:
• Keep the battery contacts clean. Soiled contacts can reduce battery
performance.
• Use batteries immediately after charging. Batteries will lose their
charge if left unused.
1 EN-EL15a/EN-EL15 batteries can also be used, but note that you may not be able to take as
many pictures on a single charge. Endurance varies with the condition of the battery, the
temperature, the interval between shots, and the length of time menus are displayed.
