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 radio and the lights should not be
operated for a long time without using the 230 V power supply.
Position See chapter 16.
Discharging The living area battery is discharged by the closed circuit current which some
electrical appliances continuously require.
A completely charged living area battery will be totally discharged via a closed
circuit current (inactive appliances).
Low temperatures outside reduce the capacity available.
The self-discharge rate of the battery is also dependant on temperature. At 20
to 25 °C the self-discharge rate is approx. 3 % of the capacity per month. The
self-discharge rate will increase with rising temperatures: At 35 °C the self-dis-
charge rate is approx. 20 % of the capacity per month.
An older battery no longer has the complete capacity available.
The higher the number of active electrical appliances, the faster the energy of
the living area battery is consumed.
Charging Only use the transformer/rectifier to charge the living area battery. Therefore,
connect the vehicle to a 230 V power supply system as often as possible.

Z Before disconnecting or connecting the terminals of the battery, switch off
the vehicle engine as well as the 230 V and 12 V power supplies and all
appliances. Danger of short circuit!
Z If the starter battery or living area battery are disconnected, do not apply
the ignition. There is a danger of short circuit from exposed cable ends.
Z For models with a Fiat base vehicle, the radio in the driver's cabin is con-
nected to the living area battery.
Z Total discharge damages the battery.
Z Recharge battery in good time.
Z Charge the battery for at least 48 hours after a total discharge.
Z Further information can be obtained in the separate documentation for the
living area battery.
Z Do not cover the ventilation slots. Danger of overheating!
