Get Servicing and Maintenance -> Charging the Conventional 12V Battery Guide for Fiat 600 SUV Second Generation (2023-2026)

WARNING The cables of the electrical

system must be correctly reconnected

to the conventional battery, i.e. the

positive cable (+) to the positive

terminal and the negative cable (–) to

the negative terminal.

SERVICE

INFORMATION

CHARGING THE

CONVENTIONAL 12V

BATTERY

In order to ensure economical and

safe vehicle operation and to maintain

the value of your vehicle, it is of vital

importance that all maintenance work

is carried out at the proper intervals as

specified.

For optimum service life of the battery,

it is essential to maintain an adequate

state of charge.

In some circumstances, it may be

necessary to charge the battery:

when using the vehicle mainly for

short journeys

if the vehicle is to be taken off the

road for several weeks

Consult a Fiat Dealership.

The conventional battery terminals

are marked with the positive (+) and

negative (-) terminal symbols, and are

shown on the cover of the battery itself.

The battery terminals must also be

corrosion-free and firmly secured

to the terminals. If a "quick-type"

conventional battery charger is used

with the battery fitted on the car, before

connecting it disconnect both cables of

the conventional battery itself. Do not

use a "quick-type" battery charger to

provide the starting voltage.

The detailed, up-to-date service

schedule for your vehicle is available at

the Fiat Dealership.

Severe operating conditions exist if one

or more of the following circumstances

occur frequently: Cold starting, stop

and go operation, e.g. for taxis and

police vehicles, trailer operation,

mountain driving, driving on poor and

sandy road surfaces, increased air

pollution, presence of airborne sand

and high dust content, driving at

high altitude and large variations of

temperature.

WARNINGS

WARNING After setting the ignition

device to STOP and closing the driver's

door, wait at least one minute before

disconnecting the electrical supply

from the conventional battery. When

reconnecting the electrical supply to

the conventional battery, make sure

that the ignition device is in the STOP

position and the driver's door is closed.

CHARGING THE

CONVENTIONAL 12V

BATTERY USING A

BATTERY CHARGER

WARNING To charge the vehicle's

battery yourself, use only a charger

compatible with lead-acid batteries with

a nominal voltage of 12 V.

Under these severe operating

conditions, certain service work may

be required more frequently than the

regular service interval indicated in

the service display. Contact a Fiat

Dealership for customised service

schedules.

WARNING Charging should be

slow at a low ampere rating for

approximately 24 hours. Regardless

of the duration of the operation, it is

always recommended to disconnect

the battery from the device as soon as

charging is complete to avoid potential

damage.

WARNING Follow the instructions

provided by the manufacturer of the

charger. Never reverse polarities.

233

WARNING For Hybrid version: the

hybrid system is connected to the 12 V

network through the DC/DC converter.

Any operation may affect the overall

behaviour of the system. To charge

the vehicle's battery yourself, use only

a charger compatible with lead-acid

batteries with a nominal voltage of 12

switch off all electrical consumers

(audio system, lighting, wipers, etc.)

switch off charger before connecting

the cables to the battery, so as to avoid

any dangerous sparks

ensure that the charger cables are in

good condition

lift the plastic cover on the (+)

terminal, if the vehicle has one

connect the positive (+) red cable of

the charger (1) fig. 303 to the positive

(+) terminal of battery (2)

connect the negative (-) black cable

of the charger (3) to a fastening bracket

on the 12 V battery's negative (-)

terminal (4) or to the vehicle grounding

point (5) near the 12 V battery in the

engine compartment

(Hybrid versions)

In case of failure, especially after long

storage, the 48 V battery may be

discharged and require a charging

process.

switch on the battery charger. At the

end of the charging operation, switch

off charger before disconnecting the

cables from battery

WARNING Do not try to charge the

hybrid system directly.The hybrid

system is connected to the 12 V

network through the DC/DC converter.

Any operation may affect the overall

behaviour of the system.

The label applied on the fuses cover

fig. 304 remind the correct connections

and to use a booster battery with the

same voltage (12 V).

WARNING Only use a specific 12 V

battery charger capable of maintaining

13.5 V with a high level of current 40-

50 A (approx. 600 W).To charge the

vehicle's battery yourself, use only

a charger compatible with lead-acid

Proceed as follows:

switch the ignition off

234

batteries with a nominal voltage of 12

V. Never use a 24 V or higher battery

booster.

Open the driver's door and turn the

ignition on without pressing the brake

pedal (to wake up the vehicle).

The hybrid system will automatically

start charging the 48 V battery after 1

minute with a 12 V power supply higher

than 13.5 V. The current supplied by

the battery charger should be about

30-50A.

In order to maintain an adequate state

of charge for starting the engine, we

recommend disconnecting the battery

if the vehicle is to be unused for an

extended period.

WARNING Follow the instructions

provided by the manufacturer of the

charger. Never reverse polarities.

Before disconnecting the battery:

close all openings (doors, boot,

windows)

switch off all electricity-consuming

devices (audio system, wipers, lamps,

etc.)

NOTE It is not necessary to disconnect

the battery.

When the appropriate energy level is

reached in the 48V battery (between

30 minutes to 40 minutes depending

on 12V battery state of charge), the

hybrid system automatically stops the

charging process of the 48 V battery.

At the end of the charging

operation, switch off charger (2) before

disconnecting the cables from 12 V

battery (1).

Proceed as follows:

switch off the ignition and wait for 4

minutes

Switch the ignition off

Switch off all electrical consumers

(audio system, lighting, wipers, etc.)

Switch off charger before connecting

the cables to the 12 V battery, so as to

avoid any dangerous sparks.

Ensure that the charger cables are in

good condition.

Lift the plastic cover on the (+)

terminal, if the vehicle has one.

Connect the cables of charger as

follows:

After accessing the battery, it is

only necessary to disconnect the (+)

terminal.

Following reconnection

After reconnecting the battery, turn on

the ignition and wait 1 minute before

starting the engine, to enable the

electronic systems to initialise.

Refit the plastic cover to the (+)

terminal, if the vehicle has one.

Operate the starter on the vehicle

and let the engine run.

WARNING For right-hand drive

Wait for it to return to idle.

versions, when the total distance

recorder has reached 62 miles (100

km), you must wait approximately 15

minutes before starting the engine.

Allow the engine to run for at least 20

minutes, with the vehicle stationary (in a

ventilate area to avoid accumulation of

exhaust gases), so that the 48V battery

reaches an adequate state of charge.

If minor problems nevertheless persist

following this operation, contact a Fiat

dealer or a qualified workshop.
