1)
For more details to cell-type allocations see section dimensional drawings.
2)
When the operating voltage is lower than the rated voltage, the same values apply as for rated voltage.
Higher values on request.
3)
With manual charging mechanism.
Weight is increased by around 5 kg if charging motor is fitted.
Weight is increased by around 2 kg if the motor-driven withdrawable assembly is used.
