Starter battery
The electrical system is single-pole and uses the
chassis and engine casing as a conductor.
The starter battery is used to start up the electri-
cal system and drive the starter motor as well as
other electrical equipment in the car.
The starter battery should be replaced by a
workshop

.
The car has a voltage-regulated AC alternator.
The starter battery is a 12 V AGM battery,
designed for the carbon dioxide reducing func-
tions, Start/Stop and regenerative charging, and
to support the functionality of the car's different
systems.
The service life and function of the starter battery
is influenced by factors such as the number of
starts, discharging, driving style, driving condi-
tions, climatic conditions etc.
•
Never disconnect the starter battery when
the engine is running.
•
Check that the cables to the starter battery
are correctly connected and properly tight-
ened.
WARNING
•
The battery can generate oxyhydrogen
gas, which is highly explosive. A spark can
be formed if a jump lead is connected
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 imme-
diately.
When connecting an external starter battery or
battery charger, use the car's charging points in
the engine compartment. The battery terminals
on the car's starter battery in the cargo area must
not be used.
During charging, both the starter battery and the
support battery are charged.
Positive charging point
Negative charging point
IMPORTANT
When charging the starter battery and the
support battery, only use a modern battery
charger with controlled charging voltage. Fast
charging function must not be used since it
may damage the battery.

An authorised Volvo workshop is recommended.
