Mini covers the high-voltage battery on the Cooper E, Cooper SE, Aceman and Countryman E for 8 years or 100,000 km for cars first registered on or after 1 November 2022. Subsequent owners are also entitled to all benefits.
That 100,000 km figure is the lowest distance cap of any manufacturer we hold verified Australian terms for — and Mini is owned by BMW, whose electric models get 160,000 km on otherwise identical warranty language.
Mini plug-in hybrids get 6 years or 100,000 km.
Like BMW, Mini publishes no capacity percentage. The only capacity language is "excessive capacity loss," undefined.
The terms
| Applies to | First registered | Years | Kilometres | Capacity guarantee | Transfers |
|---|---|---|---|---|---|
| Mini Electric — Cooper E, Cooper SE, Aceman, Countryman E | On or after 1 Nov 2022 | 8 | 100,000 km | None published | Yes |
| Mini Hybrid (PHEV) | On or after 1 Nov 2022 | 6 | 100,000 km | None published | Yes |
Why the cap matters more on a Mini than it looks
100,000 km sounds like a lot until you consider who buys a Mini Cooper SE. These are overwhelmingly city and commuter cars, often as a household's main vehicle, and 15,000–20,000 km a year is entirely ordinary. At that rate the distance cap arrives at around year six — well before the 8-year term expires.
In other words, for a typical Mini owner the kilometre limit is the binding constraint, not the time limit. A used Cooper SE with 80,000 km on it has perhaps 20,000 km of battery cover left, regardless of how many years remain.
The small-battery consideration
The original Cooper SE (F56) had just 28.9 kWh usable — one of the smallest packs ever sold in Australia — with a claimed 234 km. The newer J01 generation has 49.2 kWh usable and around 402 km.
On a small pack, every percentage point of degradation costs less absolute range than on a big one, but it hurts more proportionally against an already-short range. A 10% loss on the original Cooper SE takes a 234 km car down to roughly 210 km before you account for weather or motorway speeds.
What to check on a used Mini Electric
- The odometer against 100,000 km, which is usually the limit that runs out first
- Which generation the car is, because the packs differ by 20 kWh
- The tested State of Health, which on a short-range car changes usability, not just resale value
