Polestar covers the high-voltage battery on the Polestar 2, 3 and 4 in Australia for 8 years or 160,000 km, and it is one of the few manufacturers to write the guarantee in the exact language a buyer cares about: if the battery's State of Health drops below 70% of its original capacity, it is repaired or replaced at no cost.
The warranty applies regardless of a change in ownership, so it follows the car onto the used market.
The terms
| Applies to | Years | Kilometres | Capacity floor | Transfers |
|---|---|---|---|---|
| Polestar 2, Polestar 3, Polestar 4 — all Australian model years | 8 | 160,000 km | 70% State of Health | Yes |
Why the wording matters
Most manufacturers describe battery cover in terms of "defects" and leave capacity loss ambiguous, or use a phrase like "excessive capacity loss" without ever defining excessive. Polestar names the metric and names the number. That makes a claim a factual question rather than an argument.
It also means a tested State of Health figure maps directly onto your warranty position. If a Polestar 2 tests at 78%, you know precisely where you stand relative to the guarantee, and precisely how much buffer is left.
What to check on a used Polestar
Polestar 2 has been sold in Australia in several configurations with genuinely different packs — 66 kWh usable on the early Standard Range Single Motor, 75 kWh on the Long Range cars, and 67 and 79 kWh on the facelifted versions from 2024. Range claims across those variants run from 478 km to 659 km. Which variant you are looking at changes the expected figures substantially, so identify it before you interpret any test result.
Then check the in-service date against the 8-year term, the odometer against 160,000 km, and the tested State of Health against the 70% floor.
