Servicing and replacement
The 12 V battery is maintenance-free.
Contact Polestar Customer Support if the 12 V battery needs to be replaced.
Important
12 V terminal
In the event of a total loss of power, the vehicle can't be unlocked, as the locks are electrically operated. To access the vehicle and charge it, the vehicle can be powered for a short time using the externally accessible 12 V terminal. You can also access it by removing a small panel below the front bumper, near the front left wheel.
- Polestar recommends that the 12 V terminal only be used by service technicians for the purpose of accessing the vehicle as part of immobilization recovery.
- Only use a 12 V charger with a maximum charging current below 30 A.
- Connecting any power source that delivers a current higher than 30 A will blow the terminal fuse and thus disable it.
- Only use the 12 V terminal for short amounts of time. It is not meant as a means of powering the vehicle continuously.
