8.3.3 Living Area Battery (Power Pack SE)
8.4 Check Living Area Battery
At low outside temperatures the living area battery can lose part of its capacity. The standard values
for the power consumption are included in the following "Balance of energy consumption" table. The
indicated operating hours are estimates and will vary depending on individual circumstances.
> Take note of the battery manufacturers users and maintenance instructions.
> Prior to commencing a journey ensure the living area battery is fully charged. For this
reason charge the battery for at least 20 hours before commencing the journey.
> During the trip, use every opportunity to charge the living area battery.
> After the trip, charge the living area battery for at least 20 hours, as normally, the living
area battery is never fully charged even during lengthy mobile use.
> Use the provided power pack to charge the living area battery. Use a regulated charg-
er for external charging.
> When the living area battery is changed, only use batteries of the same type. A dryfill
battery must only ever be replaced by a dryfill battery.
> The living area battery charges more quickly when the ambient temperatures are high
(above 30 °C). The self-discharge rate at +20 °C is 2 % per month, at +40 °C it is 15 to
20 % per month.
> A satisfactory measurement of the charging condition can only be made after 4 hours
of battery charging. Immediately after charging, the battery voltage is higher, after ap-
prox. 4 hours, it sinks to the so-called off-load voltage. The off-load voltage displays
the charging condition.
Off-load voltage (measured at the poles) Charging condition
Greater than 12.80 V 100 %
Approx. 12.55 V 75 %
Approx. 12.32 V 50 %
Approx. 12.18 V 25 %
Less than
12.00 V 0 %
> For long periods of inactivity (4 weeks or more), either disconnect the living area bat-
tery or recharge it regularly.
> The dryfill battery is maintenance-free. Maintenance-free means:
- It is not necessary to check the acid level.
- It is not necessary to lubricate the battery poles.
- It is not necessary to refill the distilled water.
Even a maintenance-free dryfill battery must be charged regularly.
