A 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

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.
