Battery Life
The number of shots or movie footage that can be recorded with
fully-charged batteries varies with the condition of the battery,
temperature, the interval between shots, and the length of time
menus are displayed. Sample figures for EN-EL22 (1010 mAh)
batteries are given below.
• Still images: Approximately 270 shots
• Movies: Approximately 65 minutes at 1080/30p
Measured according to CIPA standards at 23 ±3 °C (73.4 ±5.4 °F)
with the camera at default settings, a fully-charged battery, a
1 NIKKOR VR 10–30mm f/3.5–5.6 PD-ZOOM lens, and a 16GB
SanDisk SDSDQXP-016G-J35 UHS-I microSDHC card. Value for
still images obtained under the following test conditions: pho-
tographs taken at intervals of 30 s with the built-in flash fired
with every other shot and the camera turned off and then on
after every ten shots. Value for movies obtained under the fol-
lowing test conditions: a series of 20 minute movies with a file
size of up to 4 GB were recorded; recording was only inter-
rupted when temperature warning was displayed.
The following can reduce battery life:
• Keeping the shutter-release button pressed halfway
• Repeated autofocus operations
• Taking NEF (RAW) photographs
• Slow shutter speeds
• Using a wireless mobile adapter
• Using vibration reduction mode with VR lenses
• Using zoom with power zoom lenses
To ensure that you get the most from rechargeable Nikon
EN-EL22 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.
