Battery Life
The number of shots that can be taken with fully-charged batter-
ies varies with the condition of the battery, temperature, the
interval between shots, and the length of time menus are dis-
played. Sample figures for EN-EL20 (1020 mAh) batteries are
given below.
Still images: Approximately 230
Movies: Approximately 70 minutes of HD footage at 1080/60i
Values for still images measured at 25 °C/77 °F with a fully-
charged EN-EL20 battery, a 1 NIKKOR VR 10–30mm f/3.5–5.6
lens, and a 16 GB Toshiba R95 W80MB/s UHS-I SDHC card
according to the CIPA standard under the following test condi-
tions: NORMAL-quality photographs taken at intervals of 30 s
with the flash fired with every other shot and the camera
turned off and then on after every ten shots.
The following can reduce battery life:
Keeping the shutter-release button pressed halfway
Repeated autofocus operations
Taking NEF (RAW) photographs
Slow shutter speeds
Using vibration reduction mode with VR lenses
To ensure that you get the most from rechargeable Nikon
EN-EL20 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.
