CHECKING BATTERY CHARGE
Read the battery’s voltage level on the control panel.
To read the starter battery’s charge level, the vehicle’s
ignition must be on (but without the engine running).
Before reading:
• Ensure that the battery is not being charged (i.e.
engine not running and 230 V supply not connected).
• Switch off as many lights as possible.
The following are guideline values at 20°C:
> 12.5 V Battery fully charged.
12.2 V – 12.5 V Battery 50% charged.
< 12.2 V The battery needs charging.
BATTERY CHARGING
CHARGING BATTERIES
While the motorhome is connected to a 230 V supply,
the living area’s battery is automatically charged by
the battery charger. An icon is displayed on the control
panel.
The battery charger also trickle charges the vehicle’s
starter battery.
The battery does best when charged continuously
for at least 24 hours. To “top up”, the battery can be
charged for short periods . However, to maintain the
battery’s full capacity, it should be given a full charge
from time to time.
See also “Descriptions – Electrical system”.
SILENT MODE
The battery charger can be set to operate silently
(silent mode).
The battery is then charged at a lower power.
Set the times when silent (reduced) mode is to
start and stop.
