Technical Notes-Specifications Battery Life The number of shots that can be taken with fully charged batteries varies with the condition of the batteries, temperature, and how the camera is used. The following examples assume a fully-charged EN-EL3 battery (1400 mAh) or three fresh Sanyo CR2 batteries inserted in the MS-D70 battery holder at a temperature of 20 °C (68 °F). Example 1 Zoom Nikkor AF-S DX 18-70 mm f/3.5-4.5G IF ED lens; continuous shooting mode; continuous-servo autofocus; image quality set to JPEG Basic; image size set to M; shutter speed ½50 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. Number of shots (EN-EL3): 2000 Number of shots (CR2): 560 Example 2 AF-S DX 18-70 mm f/3.5-4.5G IF ED lens; single-frame shooting mode; single-servo autofocus; image quality set to JPEG Normal; image size set to L; shutter speed ½50 s; shutter-release pressed halfway for five seconds and focus cycled from infinity to min- imum range once with each shot; built-in Speedlight fired at full power with every other shot; AF-assist illuminator lights when Speedlight is used; cycle repeated once exposure meters have turned off; camera turned off for one second with every ten shots. Number of shots (EN-EL3): 400 Number of shots (CR2): 160 The following can reduce battery life: • Using the monitor • Repeated autofocus operations • Keeping the shutter-release button • Taking NEF (RAW) photographs pressed halfway • 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 unused. • CR2 batteries should not be reused after the "battery exhausted" indicator has been displayed. Although the batteries may recover some of their charge when removed from the camera, they will be prone to sudden drops in voltage that may result in unexpected errors. CR2 Batteries CR2 batteries are best suited for use at room temperature. At low temperatures, CR2 batteries loose much of their charge. The number of shots that can be taken with CR2 batteries may very depending on their make and condition. Some makes of CR2 battery can not be used. 205
