7.3 CHECKING ELECTROLYTE LEVEL IN LEAD-

ACID BATTERIES

7.3.1 MANUAL BATTERY FILLING

To ensure correct use and to prevent premature wear of lead-
acid batteries, the electrolyte level (the liquid inside each battery 
element) must be checked. This should be done monthly. 
If  you  do  not  have  the  automatic  demineralised  water  filling 
system for the batteries, the white bayonet cap of each 
individual battery cell must be unscrewed to check the level. 

The operation must be carried out with the vehicle fully charged, 
i.e. with the charger light steady green or the charge indicator 
above the steering wheel with all the LEDs lit. 
The T1 measurement at which the electrolyte level must be 
attested when the batteries are charged is 40 mm. If it is lower, 
demineralised water (deionised or distilled) must be added. 
If the electrolyte level has fallen below T, i.e. not visible when 
the batteries are flat, demineralised water must be added up to 
T=51mm. Then fill up to T1=40mm with the batteries charged.

7.3.2 AUTOMATIC BATTERY FILLING VIA 

HYDROLINK SYSTEM

If the vehicle is equipped with the 
automatic filling system, as shown in the 
picture  below,  simply  connect  the  filling 
tube and introduce demineralised water. 
The following procedure must be carried out:

•   remove the protective cap from the filling connector;
•  immerse  the  filling  pump  tube  (side  without  connector)  in  a 

container containing demineralised water. 
Squeeze and release the pump so that 
the water is introduced into the tube and 
removes all air. Beware of water escaping 
from the tube, it is, therefore, advisable to 
direct it into the container. 
•  insert the counterpart into the battery 
side charging connector 
•  squeeze and release the pump to start 
introducing demineralised water into the 
batteries. Continue pumping until the 
consistency changes and you can no 
longer introduce demineralised water into 
the charging system. 
• disconnect the charging tube and 
replace the cap on the battery side 
connector. 
Be careful when exposing the vehicle to 
temperatures below 0°C. The charging 
system containing water may freeze and 
be damaged. If the vehicle is exposed 

to such temperatures, remove the demineralised water in the 
system by purging the hoses.
