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 550 shots
•
Continuous release mode (Nikon standard
2
)
: Approximately 2000 shots
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.
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
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 for extended periods
•
Keeping the shutter-release button pressed halfway
•
Repeated autofocus operations
•
Taking NEF (RAW) photographs
•
Slow shutter speeds
•
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.
