Total discharge
Total discharge of the battery is imminent, if a battery is completely discharged
by an active appliance and by closed circuit current and the off-load voltage
falls below 12 V.
Capacity
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 capacity of the battery reduces proportionately.
External influences, such as temperature and age may alter the storage
capacity of the battery. Capacity details refer to new batteries operating at
room temperature.

12 V power supply
When the vehicle is not connected to the 240 V power supply or the 240 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 with 12 V operation or
the heater (circulation fan) should not be operated for a long time without using
the 240 V power supply.
During heater operation, the circulation fan is switched on and off by a
thermostat control. As a result the living area battery is loaded if no
240 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.
Switching off all 12 V
appliances:
Switch off battery cut-off switch on the transformer/rectifier. Thus, the living
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.
Switching off 12 V
appliances that are not
required:
Switch off 12 V main switch on the panel. Entrance step and basic light are
still supplied with power.
Z
Total discharge damages the battery.
Z
Depending on battery technology, capacity details have a conversion factor
of 1.3 to 1.7, which lowers the real capacity by this value.
Z
To disconnect
all
electrical 12 V appliances from the power supply, discon-
nect the living area battery from the 12 V power supply. In order to do this,
actuate the switch on the transformer/rectifier.
