3.5 Battery and motor drive inspection
3.5.1 Batteries
NOTE
The life of battery packs BK1-BK4 is estimated at 12-24 months.
There is no acceptable measuring procedure to determine the bat-
tery quality.
Battery life is dependent on the charging and discharging times
which are largely determined by the user.
The user must provide the charge/discharge time ratio.
The longest charging time is approx. 12 hrs. The three LEDs light up yellow on the control
panel (3/Fig. 27 / p. 58).
One discharge cycle allows for 80 exposures with maximum kV/mAs values and transport
operation of approx. 3,000 m.
Realistic statement: The MOBILETT does not need to be charged during the 12-hour
workday.
If the minimum battery charge is reached in < 5 hrs., the battery must be replaced.
