Support battery
The support battery normally requires no more
service than the normal battery that is used for
starting. A workshop should be contacted in the
event of questions or problems - an authorised
Volvo workshop is recommended.
IMPORTANT
If the following instruction is not observed
then the Start/Stop function may temporarily
cease to work after the connection of an
external battery or battery charger:
•
The negative battery terminal on the car's
starter battery must never be used for
connecting an external battery or battery
charger - only the car chassis may be
used as the grounding point.
See Jump starting with another battery
(p. 275) for a description of how the cable
clamps must be attached.
NOTE
If the starter battery has been discharged so
much that the car has no normal electrical
functions and the engine is then jump-started
with an external battery or a battery charger,
the Start/Stop function will continue to be
activated. If the Start/Stop function then
auto-stops the engine shortly after, there is a
great risk that engine auto-start will fail due
to insufficient battery capacity, because the
battery has not had the opportunity to
recharge.
If the car has been jump-started, or if there is
insufficient time to charge the battery with a
battery charger, the recommendation is to
temporarily deactivate the Start/Stop function
until the battery has been recharged by the
car. In an outside temperature of +15 °C, the
battery needs to be charged for at least
1 hour by the car. In a lower outside tempera-
ture, the charging time may increase to
3-4 hours. The recommendation is to charge
the battery using an external battery charger.
For more information on charging the starter
battery, see Starter battery - general (p. 369).
