Start battery
The start (main) battery is used to power the
starter motor and other electrical components
and systems.
The start battery should only be replaced by a
trained and qualified Volvo service technician.
The vehicle has an alternating current generator.
The start battery is called an Absorbed Glass Mat
(AGM) 12-volt battery that is dimensioned for
use in vehicles with carbon dioxide-reducing
functions such as Start/Stop and regenerative
charging, and to support the vehicle's various
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.
WARNING
PROPOSITION 65 WARNING!
Battery posts, terminals, and related accesso-
ries contain lead and lead compounds, chemi-
cals known to the state of California to cause
cancer and reproductive harm. Wash hands
after handling.
If the start battery is being charged, the support
battery will also be charged.
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.
