Risk of damage
The batteries contain sulfuric acid which is
highly caustic and corrosive. Always wear
gloves and protective glasses while topping up.
If possible, ensure that the check is carried out
by specialised personnel.
Failure to comply with these prescriptions can
result in the risk of serious injury and serious
damages to the vehicle.
Risk of injury

• Visually check that the level of the fluid is
between the “Min” and “Max” limits. If there are
no references, check that the fluid covers the
Lead plates in the elements by approx. 5 mm.
• When required, only use distilled water to top up
the elements whose level is below the minimum.
• Diagnose the state of efficiency of the battery
charging system if a voltage level of less than
27 V (for nominal 24 V systems) is detected while
the engine is running.
• Check that the terminals and clamps are clean,
well tightened and protected by battery terminal
grease or petroleum jelly.
Some batteries are equipped with a single cover for
the inspection plugs. To access the elements, use a
lever as indicated in the figure.
