Starter Battery - Volvo XC 90 Owner's Manual

MAINTENANCE AND SERVICE

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 electrical equipment in the
car. The hybrid battery is used when the internal
combustion engine is started.
The starter battery should be replaced by a
workshop.
The starter battery is a 12V 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.
IMPORTANT
It is not possible to charge another car's bat-
tery by means of current through the charging
points. Using the charging points to charge
another car's battery may cause a fuse to
blow, which means that the charging points
will stop working.

IMPORTANT
When charging the starter battery, only use a
modern battery charger with controlled charg-
ing voltage. Fast charging function must not
be used since it may damage the battery.
