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:

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.
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.
