A 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; and 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.
