USEFUL ADVICE FOR
LENGTHENING THE LIFE
OF YOUR BATTERY
To avoid draining your battery and
lengthen its life, observe the following
indications:
❒ when you park the car, ensure the
doors, tailgate and bonnet are closed
properly;
❒ the ceiling lights must be off. The car
is however provided with an auto-
matic system for switching off inter-
nal lights;
❒ do not keep accessories (e.g.: sound
system, hazard lights, etc.) switched
on for a long time when the engine
is not running;
The total intake of these systems (factory and after-market) must be less than 0.6 mA x Ah (of the battery) as shown in
the following table:
Battery
50 Ah
60 Ah
70 Ah
90 Ah
❒ before performing any operation on
the electrical system, disconnect the
battery negative terminal cable;
❒ battery terminals shall always be
perfectly tightened.
IMPORTANT A battery which is kept
at a charge of less than 50% (optical in-
dicator with dark colour without green
area in the middle) for any length of time
will be damaged by sulphation leading to
a reduction in cranking power.
Moreover, this might lead to a higher
risk of the battery electrolyte freezing
(this may even occur at –10°C). If the
car is inactive for a long period of time,
refer to "Car inactivity", in section "Cor-
rect use of the car".
Maximum admitted stand-by intake
If after buying the car, you want to in-
stall electric accessories which require
permanent electric supply (alarm, etc.)
contact Alfa Romeo Authorized Services
whose qualified personnel, in addition
to suggesting the most suitable devices
available at Lineaccessori Alfa Romeo,
will evaluate the overall electric ab-
sorption, checking whether the car's
electric system is capable of withstand-
ing the load required, or whether it
should be integrated with a more pow-
erful battery. In fact, since these devices
continue absorbing energy even when
the ignition key is off, they gradually run
down the battery.
