3.5 Checking the battery voltage
Leisure area battery
Touch the sensor for Check leisure area battery voltage.
"
The voltage of the leisure area battery is displayed:
All LEDs light up: Battery charged sufficiently
F
Yellow and red LEDs light up: Battery partially discharged (below
F
12.4V)
Only red LEDs light up: Battery flat (below 11.5V)
F
The following table shows the correct interpretation of the voltage of the lei-
sure area battery displayed on the scale.
These values apply to actual operation, not off-load voltage.
Battery voltage
Lower than 11.5V
Risk of total
discharge discharge
12,2V to 12.7V

If the voltage does not exceed this range for several hours.
ATTENTION!
Y
Total discharge results in damage to the leisure area battery:
A low battery charge, indicated by low voltage, must be prevented.
F
Switch off some consumers in the event of overloaded power supply.

Prior to taking the vehicle out of service, ensure that no inactive con-
F
sumers are still connected.
Measuring the off-load voltage is a simple and effective method of checking
the condition of the battery. Off-load voltage is the voltage of the charged
battery in a passive state, with no current being supplied or drawn.
Take the measurement several hours after the last charging. In the mean-
time, no significant load should be placed on the battery, meaning no current
should be drawn from it. There is a risk of total discharge if the off-load vol-
tage of the battery is 12.2V or lower.
