Battery Endurance

The movie footage or number of shots that can be recorded with a fully-charged EN‑EL18c (2500 mAh) rechargeable Li-ion battery 1 is given below. Actual endurance varies with such factors as the condition of the battery, the interval between shots, and the options selected in the camera menus.

  • Photographs, single-frame release mode: Approximately 3580 (CIPA standard 2)

  • Photographs, continuous release modes: Approximately 8670 (Nikon standard 3)

  • Movies: Approximately 105 minutes 4

Actions such as the following can reduce battery endurance:

  • Using the monitor, for example for live view photography

  • Keeping the shutter-release button pressed halfway

  • Repeated autofocus operations

  • Taking NEF (RAW) photographs

  • Slow shutter speeds

  • Using camera Ethernet, Wi-Fi (wireless LAN), and Bluetooth features

  • Using the built-in GNSS receiver

  • Using the camera with optional accessories connected

  • Using VR (vibration reduction) with VR lenses

  • Repeatedly zooming in and out with AF-P lenses

To ensure that you get the most from rechargeable Nikon EN‑EL18c 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.

  • Check the condition of the battery regularly using the [Battery info] option in the setup menu. If a j icon appears in the [Calibration] field, calibrate the battery in the MH-26a battery charger ( Calibrating Batteries ). If the battery has not been used for more than six months, recharge the battery when calibration is complete.

  1. EN-EL18b/EN-EL18a/EN-EL18 batteries can also be used. Note, however, that the EN‑EL18 can take fewer pictures on a single charge than the EN‑EL18c/EN-EL18b/EN-EL18a.

  2. Lens cycled from infinity to minimum range and one photograph taken at default settings once every 30 s. Live view not used. Measured at 23 °C/73.4 °F (±2 °C/3.6 °F) with an AF-S NIKKOR 24–70mm f/2.8E ED VR lens.

  3. Image quality set to JPEG normal, image size set to large, shutter speed 1/250 s, focus cycled from infinity to minimum range three times after shutter-release button has been pressed halfway for 3 s; six shots are then taken in succession and monitor turned on for 5 s and then turned off; no operations performed until stand-by timer has expired. The cycle is then repeated. Measured at 23 °C/73.4 °F (±2 °C/3.6 °F) with an AF-S NIKKOR 70–200mm f/2.8E FL ED VR lens (VR off).

  4. Actual battery endurance as measured under conditions specified by the Camera and Imaging Products Association (CIPA). Measured at 23 °C/73.4 °F (±2 °C/3.6 °F) with an AF-S NIKKOR 24–70mm f/2.8E ED VR lens. Measurement performed at default settings.

    • Each shot can be up to 29 minutes 59 seconds in length.

    • If camera temperature rises, recording may end before maximum length or size is reached.
