Starter Battery - Volvo XC40 2019 Owner's Manual

Starter battery

The starter battery is used to start up the
electrical system and drive the starter motor
as well as other electrical equipment in the
car.
The electrical system is single-pole and uses
the chassis and engine casing as a conductor.
The car has a voltage-regulated AC alternator.
The starter battery is a 12 V battery, designed
for the carbon dioxide reducing functions
Start/stop and regenerative charging, and to
support the functionality of the car's different
systems.
The service life and function of the starter bat-
tery is influenced by factors such as the num-
ber 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.
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.
Do not connect the jump leads to any
•
fuel system component or any moving
part. Be careful of hot engine parts.
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.
Never smoke near the battery.

The service life and capacity of the
starter battery
The service life of the battery is affected by
several factors, including factors such as the
number of starts, discharging, driving style,
driving conditions, climatic conditions, etc.
Battery starting capacity decreases gradually
with time and therefore needs to be recharged
if the car is not used for a long time or when it
is only driven short distances. Extreme cold
further limits starting capacity. If the starter
MAINTENANCE AND SERVICE
battery is discharged a large number of times,
it will negatively affect the service life.
In order to maintain the starter battery in good
condition, it is recommended that there is at
least 15 minutes driving/week or that the bat-
tery is connected to a battery charger with
automatic trickle charging. A starter battery
that is kept fully charged has a maximum serv-
ice life.
Location
The starter battery is located in the engine compart-
ment.
WARNING
If the starter battery is disconnected, the
automatic opening and closing function
must be reset to work properly. A reset
must take place for pinch protection to
work.
