Starter battery

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. 283) for a description of how the cable
clamps must be attached.
NOTE
If the battery has become so discharged that
everything is "black" and in principle the car
does not have all the normal electrical func-
tions and the engine is subsequently started
using an external battery or battery charger,
then the Start/Stop function will be activated.
It will then be possible for the engine to be
auto-stopped but in the event of an auto-stop
the Start/Stop function may fail to auto-start
the engine due to inadequate capacity in the
battery.
The battery must first be charged in order to
ensure a successful auto-start after an auto-
stop. At an outside temperature of +15 °C the
battery needs to be charged for at least
1 hour. At a lower outside temperature a
charging time of 3-4 hours is recommended.
The recommendation is that the battery is
charged using an external battery charger.
If this is not possible then the recommenda-
tion is to temporarily deactivate the
Start/Stop function until the battery has been
adequately recharged.
For more information on charging the starter
battery, see Starter battery - general (p. 391).
