Aviloo is extending battery warranty to 26 countries. Poland is on the list since September.
Aviloo has launched its battery warranty for used electric vehicles in 26 European countries, and as of September it now includes Poland as well. The protection is tied to the Flash Test, and according to the company, it is available to qualifying vehicles at no extra cost.
This is an interesting move for buyers of used EVs, as it concerns the most expensive component of a car. However, the details regarding the warranty terms have not been fully disclosed yet.
The warranty relies on just one test
The program started in June 2026 in France and Sweden. It was later expanded to Germany, the United Kingdom, the Netherlands, Austria, Finland, Belgium, Switzerland, Ireland, Norway, and Denmark. As of September, Aviloo added more countries, including the Czech Republic, Spain, Italy, Portugal, Slovakia, Iceland, Cyprus, Greece, Bulgaria, Slovenia, Luxembourg, Hungary, Poland, and Liechtenstein.
The entire system is connected to the Flash Test service. It’s a quick test conducted via an OBD port designed to assess SoH, or the condition of the traction battery, regardless of what the car manufacturer shows on its screen or in diagnostics.
Aviloo targets its offerings primarily at dealers, used car sellers, and leasing companies. The logic is simple: you sell a used electric vehicle, run the test, and if the results meet certain criteria, the car comes with a battery warranty. On paper, it seems reasonable.
There’s one problem. We still don’t know how extensive this coverage is, what the payout limits are, or exactly which defects it covers. And it’s precisely this that separates marketing claims from actual value.
Aviloo adds its own battery health metrics
At the beginning of September, the company also published its own analysis of used EVs. It analyzed over 500,000 tests for 20 electric vehicle models and concluded that a car’s age and mileage only tell part of the story about its battery.
According to this analysis, after 150,000 km, the median SoH for the models tested ranged from 87% to 94%. This is a good result, at least on an overall level.
At the same time, differences between individual units of the same model were significant. For example, a Hyundai Ioniq 5 with a 72.6 kWh battery had a median SoH of 92.8% after 150,000 km, but the variation among cars exceeded 12 percentage points. The gap was even wider in other models.
This is actually the best argument for such a test. Two cars with the same model year and similar mileage can have batteries in completely different states. The issue is that the data comes from Aviloo itself, which makes money from battery diagnostics, so some skepticism is warranted.
If Aviloo offers reasonable warranty terms, it could become a useful tool for the used EV market. What do you think? When buying a used electric car, would you trust the SoH test more or the manufacturer’s warranty?
