Battery Life
The number of shots that can be taken with fully-charged batteries varies with the condition of the battery, temperature, and how the camera is used. Sample figures for EN-EL9a (1080 mAh) batteries are given below.
•Single-frame release mode (CIPA standard 1): Approximately 510 shots•Continuous release mode (Nikon standard 2): Approximately 2900 shots1 Measured at 23 °C/73.4 °F (±2 °C/3.6 °F) with an AF-S DX NIKKOR 18–55mm f/3.5–5.6G VR lens under the following test conditions: lens cycled from infinity to minimum range and one photograph taken at default settings once every 30 s; after photograph is taken, monitor is turned on for 4 s; tester waits for exposure meters to turn off after monitor is turned off; flash fired at full power once every other shot. Live view not used.
2Measured at 20 °C/68 °F with an AF-S DX NIKKOR 18–55mm f/3.5–5.6G VR lens under the following test conditions: vibration reduction off, continuous release mode, focus mode set to AF-C, image quality set to JPEG basic, image size set to M (medium), white balance set to v, ISO sensitivity set to ISO 200, shutter speed 1/250 s, focus cycled from infinity to minimum range three times after shutter-release button has been pressed halfway for 3 s; six shots are then taken in succession and monitor turned on for 4 s 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) photographs
•Slow shutter speeds
•Using a GP-1 GPS unit
•Using VR (vibration reduction) mode with VR lenses
To ensure that you get the most from rechargeable Nikon EN-EL9a 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.
