Maintaining Battery Charge
If you perform short daily trips
(approximately 10 miles/16 km), which
correspond to an annual total of 4000
miles/6000 km, or when the vehicle is
not going to be used for one week or
more, Maserati recommends connecting
the vehicle to a battery charger, to save
you the trouble of having to recharge the
battery. The battery charger will keep
the battery charged properly and at the
correct voltage levels required by the
systems and devices in the vehicle.
Before using the battery charger,
carefully follow the instructions
provided.
If you do not use a battery charger to
prevent the battery from going flat
when you are not going to use the
vehicle for long periods of time, you
need to check and recharge the battery
at least once every three weeks. Make
this check if you perform short daily
trips (approximately 10 miles/16 km)
which correspond to an annual total
of 6000 km/4000 miles. Please note
that allowing the battery to go flat
repeatedly can cause premature wear on
the internal cells and greatly reduce their
life, leading to problems with the ignition
system and other electrical/electronic
systems.
An Authorized Maserati Dealer is
available to advise you on how to
recharge your battery correctly and give
you useful information on battery care
and maintenance.
NOTE:
An Authorized Maserati Dealer can
provide you with any information about
the Maserati approved "Battery Charger
and Conditioner", available in the
"Genuine Accessories" range.
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
dangerous gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all times:
• always charge or recharge the battery
in a well-ventilated environment;
•
never charge or recharge a battery that
has frozen;
• ensure that any sparks or open flames
are nowhere near the battery while it
is charging;
• before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
