Battery Life
The number of shots that can be taken with a fully-charged EN-EL3 battery
(1400 mAh) varies with the con di tion of the batteries, temperature, and how the
camera is used. The following measurements were performed at a temperature of
20 °C (68 °F).
Example 1: 2000 shots
AF-S DX ED 18–55 mm f/3.5–5.6G lens; con tin u ous shoot ing mode; con tin u ous-
servo autofocus; image quality set to JPEG Basic; im age size set to M; shutter speed

to min i mum range three times; after six shots, mon i tor turned on for fi ve seconds
and then turned off; cycle re peat ed once exposure meters have turned off.
Example 2: 400 shots
AF-S DX ED 18–55 mm f/3.5–5.6G lens; sin gle-frame shoot ing mode; single-ser vo

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
To ensure maximum battery performance:
• Keep the battery contacts clean. Soiled contacts can reduce battery performance.
• Use EN-EL3 batteries immediately after charging. Batteries will lose their charge if
left un used.
