The battery is either a 12 V battery or, if the car is the mild hybrid1 type, a 48 V battery that also allows regenerative braking while driving.
Location
Support battery maintenance
The support battery normally requires no more service than the normal 12 V battery (starter battery). A workshop should be contacted in the event of questions or problems - an authorised Volvo workshop is recommended.
Important
If the 12 V battery is replaced, make sure you replace it with a battery with the same size, cold starting capacity and type as the original battery. Volvo recommends that you use an authorised Volvo workshop for replacing the battery.
Warning
48 V voltage can be dangerous in the event of incorrect intervention. Do not touch anything on the batteries that is not clearly described in the owner's manual.
- 48 V support battery must never be used for jump starting.
- External electrical equipment must not, under any circumstances, be connected to the 48 V battery.
- The 48 V battery may only be serviced and replaced by a workshop – an authorised Volvo workshop is recommended.
Specifications for support battery
If the car is the mild hybrid1 type, it will be equipped with a lithium-ion type 48 V battery instead.
