Starter battery - general

The starter battery is used to drive the starter

motor and other electrical equipment in the

car.

The starter battery is a traditional 12 V bat-

tery.
The service life and function of the starter

battery is influenced by factors such as the

number of starts, discharging, driving style,

driving conditions, climatic conditions, etc.

•

Never disconnect the starter battery when

the engine is running.

•

Check that the cables to the starter bat-

tery are correctly connected and properly

tightened.

IMPORTANT

When replacing the starter battery, in cars

with Start/Stop function, a battery of the

correct type must be fitted, EFB

in cars

with manual gearbox and AGM

in cars

with automatic gearbox.

IMPORTANT

If the starter battery is replaced, make sure

you replace it with a battery with the same

cold starting capacity and type as the orig-

inal battery (see the label on the battery).

NOTE

•

The starter battery's container size

should be consistent with the original

battery's dimensions.

•

The starter battery's height is different

depending on size.

Enhanced Flooded Battery.

Absorbed Glass Mat.

10 Maintenance and service

379

WARNING

•

The battery can generate oxyhydrogen

gas, which is highly explosive. A spark

can be formed if a jump lead is con-

nected incorrectly, and this can be

enough for the battery to explode.

•

The battery contains sulphuric acid,

which can cause serious burns.

•

If sulphuric acid comes into contact

with eyes, skin or clothing, flush with

large quantities of water. If acid

splashes into the eyes - seek medical

attention immediately.

IMPORTANT

When charging the starter battery or the

support battery (p. 382), only use a mod-

ern battery charger with controlled charg-

ing voltage. Fast charging function must

not be used since it may damage the bat-

tery.

IMPORTANT

If the following instruction is not observed

then the energy saving function for info-

tainment system may be temporarily dis-

engaged, and/or the message in the com-

bined instrument panel's information dis-

play about the starter battery's state of

charge may be temporarily inapplicable,

following the connection of an external

starter battery or battery charger:

•

The negative battery terminal on the

car's starter battery must never be

used for connecting an external starter

battery or battery charger - only the

car chassis may be used as the

grounding point.

See Jump starting with battery (p. 270) for

a description of how the cable clamps

must be attached.

NOTE

The life of the battery is shortened if it

becomes discharged repeatedly.
The life of the battery is affected by several

factors, including driving conditions and

climate. Battery starting capacity decrea-

ses gradually with time and therefore

needs to be recharged if the car is not

used for a longer time or when it is only

driven short distances. Extreme cold fur-

ther limits starting capacity.
To maintain the battery in good condition,

at least 15 minutes of driving/week is rec-

ommended or that the battery is con-

nected to a battery charger with automatic

trickle charging.
A battery that is kept fully charged has a

maximum service life.

NOTE

•

The higher the current take-off in the

car, the more the alternator must be

working and the batteries charging =

Increased fuel consumption.

•

When the capacity of the starter bat-

tery has fallen below the lowest per-

missible level then the Start/Stop func-

tion is disengaged.

Temporarily reduced Start/Stop function due

to high current take-off means:

•

The engine starts automatically

without

the driver depressing the clutch pedal

(manual gearbox).

•

The engine starts automatically without

the driver lifting his/her foot off the foot

brake pedal (automatic gearbox).

Location of the batteries

A: Left-hand drive car. B: Right-hand drive car.

(1) Starter battery

(2) Support battery.

The support battery normally requires no

more service than the normal starter battery.

A workshop should be contacted in the event

of questions or problems - an authorised

Volvo workshop is recommended.

IMPORTANT

If the following instruction is not observed

then the Start/Stop function may tempo-

rarily cease to work after the connection of

an external battery or battery charger:

•

The negative battery terminal on the

car's starter battery must never be

used for connecting an external bat-

tery or battery charger - only the car

chassis may be used as the ground-

ing point.

See Jump starting with battery (p. 270) for

a description of how the cable clamps

must be attached.

Automatic starting can only take place if the gear lever is in neutral position.

See Starter battery - general (p. 378) for detailed description of the starter battery.

10 Maintenance and service

384

NOTE

If the battery has become so discharged

that everything is "black" and in principle

the car does not have all the normal elec-

trical functions and the engine is subse-

quently started using an external battery or

battery charger, then the Start/Stop func-

tion will be activated. It will then be possi-

ble for the engine to be auto-stopped but

in the event of an auto-stop the Start/Stop

function may fail to auto-start the engine

due to inadequate capacity in the battery.
The battery must first be charged in order

to ensure a successful auto-start after an

auto-stop. At an outside temperature of

+15 °C the battery needs to be charged for

at least 1 hour. At a lower outside tem-

perature a charging time of 3-4 hours is

recommended. The recommendation is

that the battery is charged using an exter-

nal battery charger.
If this is not possible then the recommen-

dation is to temporarily deactivate the

Start/Stop function until the battery has

been adequately recharged.
For more information on charging the

starter battery, see Starter battery - gen-

eral (p. 378).

Battery - symbols (p. 380)

Electrical system

The electrical system is single-pole and uses

the chassis and engine casing as a conductor.

The car has a voltage-regulated AC alterna-

tor.
The size, type and performance of the starter

battery depend on the car's equipment and

function.

IMPORTANT

If the starter battery is replaced, make sure

you replace it with a battery with the same

cold starting capacity and type as the orig-

inal battery (see the label on the battery).

Starter battery - general (p. 378)

Fuses - general

All electrical functions and components are

protected by a number of fuses in order to

protect the car's electrical system from dam-

age by short circuiting or overloading.

If an electrical component or function does

not work, it may be because the component's

fuse was temporarily overloaded and failed. If

the same fuse fails repeatedly then there is a

fault in the circuit. Volvo recommends that

you visit an authorised Volvo workshop for

checking.

Changing
1. Look in the fuse diagram to locate the

fuse.

2. Pull out the fuse and check from the side

to see whether the curved wire has

blown.

3. If this is the case, replace it with a new

fuse of the same colour and amperage.

WARNING

Never use a foreign object or a fuse with

an amperage higher than that specified

when replacing a fuse. This could cause

significant damage to the electrical system

and possibly lead to fire.
