Technical Notes-Specifications Specifications Battery Life The number of shots that can be taken with an EN-EL3 battery varies with the condition of the battery, temperature, and how the camera is used. Case 1 At room temperature (20 °C/68 °F), approximately 1600 shots can be taken with a fully-charged (1400 mAh) EN-EL3 battery and an AF-S 24-85 mm f/3.5-4.5 G lens under the following standard Nikon test conditions: continuous shooting mode; continuous-servo autofocus; image quality set to JPEG Basic; image size set to Medium; shutter speed 1/250 s; shutter-release pressed halfway for three seconds and focus cycled from infinity to minimum range three times with each shot; after six shots, monitor turned on for five seconds and then turned off; cycle repeated once exposure meters have turned off. Case 2 At room temperature (20 °C/68 °F), approximately 370 shots can be taken with a fullycharged (1400 mAh) EN-EL3 battery and an AF-S 24-85 mm f/3.5-4.5 G lens under the following standard Nikon test conditions: single-frame shooting mode; single-servo autofocus; image quality set to JPEG Normal; image size set to Large; shutter speed 1/ s; shutter-release pressed halfway for five seconds and focus cycled from infinity to 250 minimum range once with each shot; next shot taken after exposure meters have turned off; built-in Speedlight fired at full power with every other shot; AF-assist illuminator lights when flash is used; camera turned off for one minute after every ten shots. 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 To ensure that you get the most from rechargeable Nikon EN-EL3 batteries: • Keep the battery contacts clean. Soiled contacts can reduce battery performance. • Use batteries immediately after charging. Batteries will lose their charge if left un- used. 197
