Battery Life

The movie footage or number of shots that can be recorded with fully-charged batteries varies with the condition of the battery, temperature, the interval between shots, and the length of time menus are displayed. Sample figures for EN-EL14a (1230 mAh) batteries are given below.

•Photographs, single-frame release mode (CIPA standard 1): Approximately 600 shots

•Photographs, continuous release mode (Nikon standard 2): Approximately 2000 shots

•Movies: Approximately 50 minutes at 1080/60p and 1080/50p 3

1 Measured at 23 °C/73.4 °F (±3 °C/5.4 °F) with an AF-S DX NIKKOR 18–55mm f/3.5–5.6G VR lens under the following test conditions: lens cycled from infinity to minimum range and one photograph taken at default settings once every 30 s; after photograph is taken, monitor is turned on for 4 s; tester waits for standby timer to expire after monitor is turned off; flash fired at full power once

every other shot. Live view not used.

2Measured at 20 °C/68 °F with an AF-S DX NIKKOR 18–55mm f/3.5–5.6G VR lens under the following test conditions: vibration reduction off, continuous high- speed release mode, focus mode set to AF-C, image quality set to JPEG basic, image size set to M (medium), white balance set to v, ISO sensitivity set to

ISO 100, 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 4 s and then turned off; cycle repeated once standby timer has expired.

3Measured at 23°C/73.4°F (±3°C/5.4°F) with the camera at default settings and an AF-S DX NIKKOR 18–55mm f/3.5–5.6G VR lens under conditions specified by the Camera and Imaging Products Association (CIPA). Individual movies can be up to 20 minutes in length or 4 GB in size; recording may end before these limits are reached if the camera temperature rises.

The following can reduce battery life:

•Using the monitor

•Keeping the shutter-release button pressed halfway

•Repeated autofocus operations

•Taking NEF (RAW) photographs

•Slow shutter speeds

•Using the built-in Wi-Fi or location data functions, or using an optional location data unit

•Using an Eye-Fi card

•Using VR (vibration reduction) mode with VR lenses

To ensure that you get the most from rechargeable Nikon EN-EL14a 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.
