4.3. Battery filling

Verify the electrolyte level using the floats in the center
of each filling cap.
Float doesn't emerge
è Insuffisant level
NOTE
Tilt the charger to gain access to the front
battery pack.
If necessary, fill the battery cells after the charge using
the centralised water filling system.
! CAUTION
Use only distilled or demineralised water to
fill the battery cells.
! CAUTION
Battery cells filling must be performed only
after charge (during charge, electrolyte level
increases and can overflow).

Float emerges
è Correct level
1- Ensure that the water can of the filling unit is
filled sufficiently with distilled water.
2- Position and hold the ELECTRICAL BATTERY
FILLING switch either to the left or to the right
to activate the filling unit.
3- Release the ELECTRICAL BATTERY FILLING
switch when the flow indicator stops turning.
4- Verify the proper electrolyte level in each
battery cell.
4.4. Electrolyte specific gravity
and battery voltage
Specific gravity and voltage measure is the most
important check to be performed on a battery. A
hydrometer is supplied with the work platform.
Specific gravity and voltage readings must be
performed at least once a month and recorded in a
battery service log.
The state of charge of the battery can be checked
by measuring the specific gravity of the electrolyte.
This value decreases as the battery discharges.
When the battery is fully charged, the specific gravity
is 1.280 kg/l.
When the battery is 80% discharged, the specific
gravity is 1.150 kg/l.
The following graphic shows the correspondence
between specific gravity and battery discharge.
