A Battery Life
The number of shots that can be taken with a fully-charged EN-EL4a
battery (2,500 mAh) varies with the condition of the battery, temperature,
and how the camera is used.
Sample figures are given below.
• CIPA standard: Approximately 4,400 shots. Measured at 23 °C/73.4 °F (±2 °C/
3.6 °F) with an AF-S NIKKOR 24–70mm f/2.8G ED lens under the following
test conditions: lens cycled from infinity to minimum range and one
photograph taken at default settings once every 30 s. Live view not used.
• Nikon standard: Approximately 5,300 shots. Measured at 20 °C/68 °F with an
AF-S VR 70–200mm f/2.8 ED lens under the following test conditions: image
quality set to JPEG normal, image size set to L (large), 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) or TIFF (RGB) photographs
• Slow shutter speeds
• Using the optional WT-4 wireless transmitter
• Using the optional GP-1 GPS unit
• Using VR (vibration reduction) mode with VR lenses
To ensure that you get the most from rechargeable Nikon EN-EL4a
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.
• Check the condition of the battery regularly using the [Battery info]
option in the setup menu (pg. 355).
If [j] is displayed for
[Calibration], calibrate the battery using the MH-22 quick charger.
