To connect the battery to the camera:
Ensure that the main switch on the camera is off.
Plug the battery cable KC-20S or KC-29S (spiral cable) into the power
supply socket on the camera and the battery 28 V output socket.
Note: When the battery voltage drops below the warning level, the BAT1 level in the
camera display will start flashing. A white "i" will appear, signaling more information is
available on the INFO screen.
Note: For more information on setting the low battery warning level, see
Menu>System>Power (on page 91).

7.5 Onboard Batteries
The camera can be equipped with adapters for either V-Lock or Gold Mount
video-style batteries.
Four different adapters are available:
BAB-G: Back-mount adapter Gold Mount batteries
BAB-V: Back-mount adapter V-Lock batteries
BAT-G: Top-mount adapter Gold Mount batteries
BAT-V: Top-mount adapter V-Lock batteries
Note: Adapters must be installed by a trained technician!
7.6 V-Lock Batteries
V-Lock batteries are available from a number of manufacturers. Some of
these batteries are able to transmit information on their remaining capacity to
the camera. ALEXA displays the remaining capacity in percent on the
Homescreen of the camera display. For these batteries, the user does not
need to set the battery warning level due to the communication of camera
and battery. Currently, batteries by ID-X, Bebop or any battery using the TI-
protocol for battery communication will have their capacity displayed as
percentage in the camera.
