Capacity refers to the amount of electricity which can be stored in a battery.
The capacity of a battery is given in ampere hours (Ah). The so-called
K20 value is normally used.
The K20 value indicates how much current a battery is able to dispense over
a time period of 20 hours without causing damage, or how much current is
required to charge a flat battery within 20 hours.
For example, if a battery can dispense 4 amps for 20 hours, then it has a
capacity of 4 A x 20 h = 80 Ah.
If more current flows, the discharging time of the battery will decrease pro-
portionately.
External influences, such as temperature and age may alter the storage ca-
pacity of the battery. Capacity details refer to new batteries operating at
room temperature.

Depending on battery technology, capacity details have a conversion
factor of 1.3 to 1.7, which lowers the real capacity by this value.
9.3 12 V power supply

To disconnect all electrical 12 V appliances from the power supply, dis-
connect the living area battery from the 12 V power supply. In order to
do this, actuate the switch on the transformer/rectifier.
When the vehicle is not connected to the 230 V power supply or the 230 V
power supply is switched off, the living area battery supplies the living area
with 12 V DC. The living area battery has a limited power supply only. For
this reason, electrical appliances such as the refrigerator and the heater(cir-
culation fan) should not be operated for a long time without using the 230 V

power supply.

During heater operation, the circulation fan is switched on and off by a ther-
mostat control. As a result the living area battery is loaded if no 230 V power
supply is connected.
In the case of longer lay-ups of the vehicle, all 12 V appliances must be
switched off to avoid discharging the living area battery.

Switch off battery cut-off switch on the transformer/rectifier. Thus, the liv-
ing area battery is fully disconnected from all electrical appliances.
If you leave the vehicle briefly and the refrigerator and/or the heater shall
continue working, it suffices to switch off all 12 V appliances not required.
Yet nevertheless, observe the charging condition of the living area battery.

Switch off 12 V main switch on the panel. Entrance step and basic light
are still supplied with power.
