• To access the battery lift the ground
coverage of the boot compartment
and remove the battery access cover
(see paragraph "To Disconnect the
Battery" in this chapter).
• Remove the protection cover and
connect the terminal clamp of the
charger positive cable (typically in
red) to the positive post (+) of the
battery.
• Connect the terminal clamp of the
charger negative cable (typically
in black) to the nut located by the
negative post (–) on the battery,
indicated in the picture.
The vehicle is equipped with a IBS
(Intelligent Battery Sensor) sensor able
to measure charging and discharging
currents and to calculate the state
of charge and state of health of the
battery. This sensor is located in at the
negative post (–) of the battery.
For a successful charge/recharge
operation, the charging current must
flow through the IBS sensor as shown
in the picture.
• Turn the charger on and follow the
instructions on its user manual to
completely recharge the battery.
• When the battery is recharged,
turn off the battery charger before
disconnecting it from the battery.
• Disconnect first the terminal clamp
of the charger black cable from the
battery and then the terminal clamp
of the red cable.
• Reassemble the protection cover
on the battery positive post and
the other parts removed for this
operation.
Maintaining Battery Charge
If you perform short daily trips
(approximately 16 km/10 miles),
which correspond to an annual total
Maintenance and Care
of 6000 km/4000 miles, 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 16
km/10 mi) 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.
The Service Network is available to
advise you on how to recharge your
battery correctly and give you useful
