The Austrian battery-testing firm Aviloo has extended its battery warranty for used electric cars to 26 European countries, it said on 8 September 2026. The cover is free, and it attaches automatically to any Flash Test that meets the qualifying criteria.
What you actually get
The Flash Test is Aviloo's quick diagnostic: it reads the high-voltage battery's State of Health over the OBD port, independently of whatever the manufacturer's own display claims. A test that qualifies carries one year of warranty at no additional charge.
If the battery's SoH falls below a calculated limit during that year, the holder receives €3,000 in compensation and the cost of the test is refunded.
| Terms as published | |
|---|---|
| Price of cover | Free with a qualifying Flash Test |
| Duration | One year |
| Payout | €3,000 plus reimbursement of the test cost |
| Trigger | SoH falls below a calculated limit |
| Measured via | OBD interface, independent of manufacturer readout |
The qualifying SoH threshold is not published, and neither is the underwriter. Electrive's own assessment is blunt about it: on the information released so far, the extent of the protection cannot be judged, because the specific warranty terms would be the deciding factor. Treat the €3,000 as the headline and the small print as unseen.
Where it applies in Europe
Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Liechtenstein, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the UK.
It is a trade product
This is aimed at dealerships, used-car traders and leasing companies — the people who need an independent number to stand behind a car they are selling. A private seller is not the customer.
That shapes how to read it. A free warranty attached to a test is a sales tool for the test: it makes the dealer's SoH figure credible by putting money behind it, which is precisely the friction in used EV sales right now. Buyers do not trust a number the seller produced.
Why it lands for a used Tesla buyer
Because Tesla is the volume car in Europe's used EV market — and because Aviloo's own dataset puts Teslas closer to the threshold than most people assume.
TeslAnt covered the company's Battery Report drawn from more than 500,000 tests. Ranked by median State of Health at 150,000 km, the Model Y comes 15th of 20 models at 90.3% and the Model 3 17th at 88.9%, against leaders around 94%. Sixteen of the twenty models still hold at least 90%; the remaining four sit between 85% and 90%, and one of them is a Tesla.
That cuts against the intuition that a warranty is only worth having on a weak car. A Model 3 near the bottom of a tight field is exactly the case where a calculated SoH limit and a €3,000 payout stop being theoretical. If you are buying a used Model 3 or Model Y from a European dealer, the practical questions are now specific: was a Flash Test done, did it qualify, what limit was calculated for that car, and does the year of cover transfer to you.
The report's own headline finding argues the same way. Aviloo's conclusion was that the spread between individual cars of the same model widens with mileage, so the badge narrows the likely outcome without settling it. A warranty priced off a test on the actual car is a direct answer to that spread.
The regulatory backdrop
Independent testing is filling a gap regulation has not closed. France's industry signed a voluntary pact on displaying used-EV battery health on 4 September, with no obligation behind it, and UK bodies have pushed for mandatory battery health certificates on dealer-sold used EVs. The binding instrument, the EU battery passport, arrives in February 2027.
Until then a commercial warranty from a testing company is the closest thing European used-EV buyers have to a guarantee — which is both the opportunity Aviloo is taking and the reason to read terms it has not yet published.
