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.

EN-EL15c/EN-EL15a/EN-EL15 batteries can also be used. Note, however, that you will not be able to take as many pictures on a single charge using EN-EL15a/EN-EL15 batteries. Endurance varies with the condition of the battery, the temperature, the interval between shots, and the length of time menus are displayed.
