CHARGING THE BATTERY
IMPORTANT The battery charging pro-
cedure is described only for information pur-
poses. This operation should be carried out
by Alfa Romeo Authorised Services.
Charging should be slow at a low amp rat-
ing for 24 hours. Charging for a longer time
may damage the battery.
Charge the battery as follows:
– Disconnect the battery negative termi-
nal ( – ).
– Connect the charger cables to the bat-
tery terminals ensuring that the bias is cor-
rect.
– Turn on the charger.
CHECKING THE CHARGE
The battery charge may be checked satis-
factorily using the indicator, and acting ac-
cording to the colour the indicator shows.

No action
– After charging, turn off the charger be-
fore disconnecting it from the battery.
– Re-connect the battery negative termi-
nal ( – ).
IMPORTANT If the battery is kept with
a charge of below 50% it is damaged by sul-
phation, its starting capability is reduced and
it is also more subject to the possibility of
freezing (this may occur already at -10 °C).
In the event of prolonged inactivity, refer
to the paragraph “Vehicle inactivity”, in the
chapter “Correct use of the car”.
Never attempt to charge a
frozen battery: it must
firstly be thawed, otherwise it
may burst. If freezing has occurred,
the battery should be checked be-
fore charging by specialised per-
sonnel, to make sure that the in-
ternal elements are not damaged
and that the body is not cracked,
with the risk of leaking poisonous
and corrosive acid.
WARNING
Working with a low fluid
level may damage the bat-
tery irreversibly, even causing it to
burst.
