Support battery maintenance
The support battery normally requires no more service than the normal 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
Mild hybrid type cars have components that work with 48 V voltage, which can be dangerous in the event of incorrect intervention. Do not touch components that are 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.
