There is no display in the battery itself which enables its remaining charge level to be checked.
While the battery is installed in the detector, the remaining charge level information is output
from the management circuit (BMU: battery management unit) incorporated inside the battery,
and a 3-segment scale is displayed using the software in the Image Capture Computer.
The table below shows the remaining battery charge levels.
Display status Remaining charge level Prohibited operations, etc.
100 to 60%
59
to 9%
8
to 5%
Another 6 images can be taken using a
100-second cycle operation.
4
to 0%
Imaging operations are prohibited.
Operation will continue for 16 minutes
in the sleep mode.
The remaining charge level is posted with the detector serving as the master. Immediately after
the power of the detector is turned on, this level is read from the battery and sent to the software
in the image capture computer. After this, the level is read inside the detector from the battery at
fixed intervals, but no data is sent until a level below that indicated by the red underbars in the
above table is read.
The figure below shows the correlation between the discharge curves, remaining charge level
prediction curves and posting of the remaining charge level displays.
