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. In the case of AA
batteries, capacity also varies with make and storage conditions; some batteries can
not be used. Sample figures for the camera and optional MB-D11 multi-power
battery pack are given below.
• CIPA standard
1
One EN-EL15 battery (camera) : Approximately 1050 shots
One EN-EL15 battery (MB-D11) : Approximately 1050 shots
Six AA batteries (MB-D11) : Approximately 650 shots
Two EN-EL15 batteries (one in camera and one in MB-D11) : Approximately 2100 shots
• Nikon standard 2
One EN-EL15 battery (camera) : Approximately 4500 shots
One EN-EL15 battery (MB-D11) : Approximately 4500 shots
Six AA batteries (MB-D11) : Approximately 1700 shots
Two EN-EL15 batteries (one in camera and one in MB-D11) : Approximately 9000 shots
1 Measured at 23 °C/73.4 °F (±2 °C/3.6 °F) with an AF-S DX NIKKOR 18–105mm f/3.5–5.6G
ED 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; flash fired once
every other shot. Live view not used.
2 Measured at 20 °C/68 °F with an AF-S NIKKOR 70–200mm f/2.8G ED VR II lens under the
following test conditions: image quality set to JPEG basic, image size set to M (medium),
shutter speed
1 /
250
s, shutter-release button pressed halfway for three seconds and focus
cycled from infinity to minimum range three times; six shots are then taken in succession
and monitor turned on for five seconds and then turned off; cycle repeated once
exposure meters have turned off.
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 optional WT-4 wireless transmitter
• Using a GP-1 GPS unit
• Using VR (vibration reduction) mode with VR lenses
To ensure that you get the most from rechargeable Nikon EN-EL15 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.
