For a discharged battery, the acid density
must be no lower than 1.14 kg/l.
Checking the battery charge sta-
tus and calibrating the battery
charge indicator
CAUTION
Deep discharges shorten the service life of the bat-
tery.
Deep discharge begins when the battery charge dis-
play is red (3) (0% of the available battery capacity,
i.e. approx. 20% of the nominal capacity).
–
Deep discharge must be avoided (see the section
entitled "Equalising charge to prevent a deep dis-
charge of the battery").
–
Stop working with the truck immediately.
–
Charge the battery immediately.
–
Do not leave batteries in a discharged or partly
discharged state.
–
Apply the parking brake.
–
Switch on the truck.
–
Read the charge status on the display of
the display-operating unit.
–
Charge a discharged or partly discharged
battery.

Yellow:
Charge the battery soon.
3
Red:
Stop working. Charge the battery imme-
diately. The battery is at risk of deep dis-
charge.
Calibrating the battery charge indicator
When the battery is replaced, the discharge of
the newly inserted battery may be calculated
and displayed incorrectly due to different age-
ing or discharge. This can even occur when
the same battery types are used. Therefore,
the Access authorisation for the fleet manag-
er allows the battery charge indicator to be
