•
Before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
connected to the battery safely and
correctly.
It is possible to recharge the battery
without disconnecting the cables of
the vehicle electrical system.
• 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 an 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 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.
Maintenance and Care
• 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 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 and/or connecting the
battery charger, carefully follow the
instructions provided.
