Battery - check the charge capacity
Note
The vehicle must have remained turned off for at least 2 hours.
4.10.1
Check the charge indicator “inspection
glass” at Delivery inspection
Carry out a visual inspection on the charge indicator “inspection
glass” -arrow-.
The Charge indicator “inspection glass” informs the battery
charge condition.
Note
♦
Since the inspection glass is located on a single battery cell,
the indication only refers to this cell. A precise assessment on
the battery condition is only possible through a test to check
the battery charge capacity
♦
Specially when a battery is recharged, that is, even when the
battery is charged during driving, air bubbles can form under
the inspection viewing glass. These bubbles change the color
indication in the inspection viewing glass.
♦
The inspection viewing glass may be located at various posi‐
tions on the battery.
– Before making the visual inspection, tap lightly and carefully
with a screwdriver handle on the charge indicator glass
-arrow- so that air bubbles do not interfere with the inspection.
This way, any air bubbles that could influence the indicator are
eliminated and dissipate.
The color indication of the “inspection glass” becomes more ac‐
curate. There are three possible indications:
– Green → the battery is sufficiently charged.
– Black → no charge or insufficient charge, the battery must be
charged (repair measure). For battery recharging procedures
– Colorless or yellow → the battery must be replaced (repair
measure).
