This section contains instructions on the storage of the living area battery.

Store the disconnected battery in a cool and dry place.

In the case of a disconnected, fully charged gel battery it may suffice to
recharge the battery after 6 months.
Recommendation: Also charge a gel battery for 24 to 48 hours every 4 to
6 weeks.

If there is an "intelligent" charger with float charge functionality, have the
charger connected to the battery and switched on over the entire lay-up
time.
Fig. 130 Connecting auxiliary battery
To ensure that all batteries are charged or used up equally, the batteries are
connected according to Fig. 130.
8.3.6 Energy balance of the living area battery
The living area battery has a limited power supply only. For this reason, the
electrical appliances should not be operated without a 230 V power supply
for a longer period of time.
Below, the calculation of the maximum operating time of the currently availa-
ble battery capacity is described.

The example calculation refers to a new, optimally charged battery. The
actual effective battery capacity depends on the current charging condi-
tion and the age of the battery. The current battery capacity can be de-
termined by means of special indicator units.

If there is a second living area battery, the available capacity doubles.

All lamps are LED lamps with very low power consumption. Approxi-
mately 2 W of power consumption can be expected per LED lamp.

Record the daily requirement. Note the switching on times and the
power output of the devices used (see table below).
