Battery Life
The number of shots that can be taken with fully-charged batteries varies with the
condition of the battery, temperature, and how the camera is used.
Sample figures
for EN-EL9a (1080 mAh) batteries are given below.
Single-frame release mode (CIPA standard
1
): Approximately 550 shots
Continuous release mode (Nikon standard
2
): Approximately 2000 shots
1 Measured at 23 °C/73.4 °F (±2 °C/3.6 °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
exposure meters to turn off after monitor is turned off; flash fired at full power
once every other shot.
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 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 exposure meters have turned off.
The following can reduce battery life:
Using the monitor for extended periods
Keeping the shutter-release button pressed halfway
Repeated autofocus operations
Taking NEF (RAW) photographs
Slow shutter speeds
Using VR (vibration reduction) mode with VR lenses
To ensure that you get the most from rechargeable Nikon EN-EL9a 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.
