Values for off-load voltage Charging condition of the battery
Less than 12 V Discharge or totally discharge
12.2 V 25 %
12.5 V 50 %
More than 12.7 V 100 %
Z Total discharge causes irreparable damage to the battery.
Z Measure the off-load voltage preferably several hours after the previous
charging (e.g. in the morning) and not directly after a current drain.
Z When leaving the vehicle, switch off the main 12 V power supply at the
panel. This prevents any unnecessary discharge of the living area battery.
Z The refrigerator control takes power from the battery capacity, even if the
12 V main switch is switched off. Therefore disconnect the living area bat-
tery from the 12 V power supply, if the vehicle will not be used for a long
period of time.
Z If the vehicle is not connected to the 230 V power supply and the water
pump is not used for a longer period of time: Switch off the power supply
for the water pump. The pump relay uses around 4 Ah current each day.
