If you use another type of battery, have the
battery type set with a diagnostic tester by a
qualified specialist workshop.
R
use batteries of the same age
Do not combine old and new batteries.
Checking the battery charge level
If the vehicle is used often or predominantly over
short distances or is parked for a long period,
check the battery charge level more often.
X
Disconnect the batteries.
X
Wait for approximately 8 seconds.
X Measure the no-load voltage of the battery.
X If the no-load voltage of the battery is over
12.6 V, reconnect the battery.
X
If the no-load voltage of the battery is under
12.6 V, charge the battery separately.
Charging the batteries
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases
can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Use a commercially-available battery
charger to charge the batteries. Make sure
that the charging voltage is correct. Do not
charge new batteries with rapid charging. The
charge current of used batteries should be
maximum 75 % of the battery capacity for
rapid charging. Otherwise, you could damage
the batteries.
! The charge current should not exceed 10%
of the battery capacity. A higher charge cur-
rent can damage the batteries.
Charge the batteries when the outside temper-
ature is above 0 †. The optimal outside tem-
perature is between 10 † and 25 †.
X Remove the batteries.
X
Unscrew the battery cell caps.
X
Check the battery fluid level.
X Charge the batteries separately.
X Connect and switch on the battery charger.
See the battery charger's operating instruc-
tions.
X If the batteries are charged, deactivate the
battery charger and screw the plugs into the
batteries.
X
Fit the batteries.
i After charging/replacing the batteries, the
battery charge level calculated may not be
correct. It takes approximately 3 days while
the vehicle is in operation for the teach-in
process to be completed.
The following event window displays are only
correct once the teach-in process has been
completed:
R
Consumer shutoff active
R
Battery charge level low
R
Battery charge level too low Start
engine
Checking the battery fluid level
! Tap water reduces the electrical power out-
put of the batteries. Add only distilled or de-
ionised water.
Do not use a metal funnel when adding distil-
led water. The metal funnel may cause a short
circuit and the batteries may be damaged.
Batteries in the chassis, one beside the other
(example: tractor/semitrailer combination)
Observe the safety notes on handling batteries.
