Battery Life - Nikon D100 Manual

Battery Life

The number of shots that can be taken with an EN-EL3 battery varies with the condition
of the battery, temperature, and how the camera is used.
Case 1
At room temperature (20 C/68 F), approximately 1600 shots can be taken with a
fully-charged (1400 mAh) EN-EL3 battery and an AF-S 24–85 mm f/3.5–4.5 G lens un-
der the following standard Nikon test conditions: continuous shooting mode; continu-
ous-servo autofocus; image quality set to JPEG Basic; image size set to Medium; shutter
1
speed / s; shutter-release pressed halfway for three seconds and focus cycled from
250
infinity to minimum range three times with each shot; after six shots, monitor turned
on for five seconds and then turned off; cycle repeated once exposure meters have
turned off.
Case 2
At room temperature (20 C/68 F), approximately 370 shots can be taken with a fully-
charged (1400 mAh) EN-EL3 battery and an AF-S 24–85 mm f/3.5–4.5 G lens under the
following standard Nikon test conditions: single-frame shooting mode; single-servo
autofocus; image quality set to JPEG Normal; image size set to Large; shutter speed
1
/ s; shutter-release pressed halfway for five seconds and focus cycled from infinity to
250
minimum range once with each shot; next shot taken after exposure meters have turned
off; built-in Speedlight fired at full power with every other shot; AF-assist illuminator
lights when flash is used; camera turned off for one minute after every ten shots.
The following can reduce battery life:
• Using the monitor
• Keeping the shutter-release button pressed halfway
• Repeated autofocus operations
• Taking NEF (raw) or TIFF-RGB photographs
• Slow shutter speeds
To ensure that you get the most from rechargeable Nikon EN-EL3 batteries:
• Keep the battery contacts clean. Soiled contacts can reduce battery performance.
• Use batteries immediately after charging. Batteries will lose their charge if left un-
used.
