Step 2: Stopping a charge
The charger will stop automatically when the charger reaches a full charge, detects a
disconnection of the charge connector, or will stop when a fault occurs. It can be manually
stopped as well if the operator presses the “Stop” button.
NOTE: It is not necessary to press the red OFF button to terminate a charge. The OFF button
is only used to remove power to the system.
After a charge has been completed or stopped by the user, the screen will indicate the method
by which the charge was stopped. The display will also contain the data values obtained at the
end of charging (see Figure 5.5).

NOTE: If the operator disconnects the cables without pressing STOP, the charger will
immediately stop charging and prevent any arcing or damage to either the charger or battery.
Step 3: Disconnect battery cables from charger
5.3 Equalization
Proper equalization is necessary for the health of the pack. Too little equalizing may lead to
sulfation and decreased capacity, whereas excessive equalizing may lead to high water loss and
more maintenance. Webasto recommends equalizing at least once a week.
The equalization schedule is stored in the BMID and is automatically initiated according to its
preprogrammed schedule. To manually schedule an equalization during a charge, simply press
the “Equalize” button at any time during a charge, the equalize light will start flashing
indicating an equalization is scheduled, and the battery pack will be equalized following the fast
charge.
