What to do if the voltage of Battery II is too low for Truma BC 616 IU to start?

If the voltage of Battery II has dropped below 1.5 V and the mains charging process won't start, start the motor and let it run for about 30 seconds. This should raise the battery voltage above 1.5 V, allowing the charging process to start automatically.
