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-D80 multi-power battery pack are given below.
• CIPA standard

1

One EN-EL3e battery (camera)

: Approximately 850 shots

One EN-EL3e battery (MB-D80)

: Approximately 850 shots

Two EN-EL3e batteries (MB-D80)

: Approximately 1700 shots

six AA batteries (MB-D80)

: Approximately 600 shots

• Nikon standard

One EN-EL3e battery (camera)

: Approximately 4200 shots

One EN-EL3e battery (MB-D80)

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; 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. Live view not used.

2 Measured at 20 °C/68 °F with an AF-S DX NIKKOR 18–105mm f/3.5–5.6G ED VR lens under

the following test conditions: release mode set to

9, autofocus mode set to AF-C, image

quality set to JPEG basic, image size set to M (medium), white balance set to A, ISO
sensitivity set to ISO 200, shutter speed

s, focus cycled from infinity to minimum range

three times after exposure meters have been on 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
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-EL3e 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.
