Battery Life
Battery life varies with charge state and shooting conditions. The number of shots that can be taken
with a fully-charged EN-ELg battery (lO00mAh) is approximately 470 shots in single-frame shooting
mode and 2,200 shots in continuous shooting mode. Battery life for single frame shooting mode is
measured according to CIPA standards (lens cycled from infinity to minimum range and shutter
released at default settings once every 30s; flash fired with every other shot). Battery life for continu-
ous shooting mode is measured with image quality set to JPEG Basic, a shutter speed of Y2s0s, t he
shutter release pressed halfway for three seconds and focus then cycled from infinity to minimum
range three times; after six shots, the monitor is turned on for five seconds and then turned off; the
cycle is repeated once exposure meters have turned off. All measurements are performed with an 18
55ramf/3.S
B.6GII ED AF-S DX Zoom-Nikkor lens.
The following car/reduce battery life:
. Using the monitor • Taking RAW (NEF) photographs
. Keeping the shutter-release button pressed half- • Slow shutter speeds
way . Using vibration reduction with VR lenses
. Repeated autofocus operations
To ensure maximum battery performance:
. Keep the battery contacts clean. Soiled contacts can reduce battery performance.
. Use batteries immediately after charging. Batteries will lose their charge if left unused.
The battery level displayed by the camera may vary with changes in temperature.
