Battery Life - Nikon D5100 Reference Manual

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-EL14 (1030 mAh) batteries are given below.
• Single-frame release mode (CIPA standard
• Continuous release mode (Nikon standard
1 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.
2 Measured 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 100, shutter
1
speed /
250
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-EL14 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.
