Start battery
The vehicle's electrical system is single pole and
uses the body and engine block as conductors.
The start (main) battery is used to power electri-
cal components and systems. However, the
hybrid battery is used to start the gasoline
engine.
The start battery should only be replaced by a
trained and qualified Volvo service technician.
The start battery is an Absorbed Glass Mat
(AGM) 12-volt battery that is dimensioned for
use in vehicles to support electrical systems and
functions.
The service life of a battery is affected by factors
such as driving conditions/style, the number of
starts, climate, etc. Extreme cold may also further
decrease the battery’s starting capacity.
•
Never disconnect the start battery while the
engine is running.
•
Check that the start battery is correctly con-
nected and that the clamps on its terminals
are properly tightened.
WARNING
•
Never expose the battery to open flame
or electric spark.
•
Do not smoke near the battery.
•
Battery fluid contains sulfuric acid. Do not
allow battery fluid to contact eyes, skin,
fabrics or painted surfaces. If contact
occurs, flush the affected area immedi-
ately with water. Obtain medical help
immediately if eyes are affected.

It is not possible to charge another vehicle's bat-
tery using the connection points in the engine
compartment. If the connection points are used
to charge another vehicle's battery it may cause a
fuse to blow, which means that the connection
points will not function.
If an external auxiliary battery is used to start the
vehicle, use the connection points in the engine
compartment. The start battery's terminals should
never
be used. See the following illustration.
