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

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.
2 Measured 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.
3 Measured 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.
