Independent EV battery diagnostic company AVILOO has launched a battery warranty to provide used EV buyers with genuine, financially backed protection based entirely on independent battery health data.

The warranty comes into effect in July in the UK, launching simultaneously in Germany, the Netherlands, Finland, Austria, Belgium, Ireland and Switzerland, following successful rollouts in France and Sweden in June.

For most consumers, the battery - the single most expensive component in any electric vehicle - remains an unknown quantity at the point of purchase. Manufacturer-reported health figures are neither independently verified nor standardised. The AVILOO Battery Warranty changes that.

The Battery Warranty is issued as a standalone document, separate from AVILOO’s existing independent battery certificate. It is managed through AVILOO Connect, a new digital dashboard for professional EV remarketing, giving dealers, fleet operators, and remarketing platforms a single interface to manage battery test lifecycles from incoming inspection through to warranty issuance.

For each vehicle, an individual State of Health (SoH) floor is calculated using AVILOO’s proprietary diagnostics database - the largest battery health dataset in the world. The calculation sets the minimum SoH the battery must maintain at 20,000 kilometres over the one-year warranty period. Dealers can offer this warranty to buyers as a credible, independently underwritten selling point, without carrying the risk themselves.

Buyers receive a one-year warranty period during which they can carry out an AVILOO FLASH Test - a three-minute, manufacturer-neutral diagnostic that assesses real battery capacity, thermal management, and charging capability against original factory specifications, covering 96% of EV models currently on the road.

If the battery’s SoH falls below the calculated threshold during the warranty period, the buyer receives £2,700 in compensation plus a full refund of the FLASH Test costs. This is a concrete, unconditional financial backstop, not a vague assurance.

Marcus Berger, CEO of AVILOO, said: “The AVILOO Battery Warranty raises the used electric vehicle market to a new level. For the first time in the UK, we are providing the foundation for a warranty based solely on objective, independent measurement data. This builds trust and gives British dealers and buyers a level of certainty that simply has not existed before. The UK has one of Europe’s most dynamic used EV markets, and we see enormous appetite from both dealers and consumers to get this right. With the Battery Warranty, we are setting a new industry standard - one that provides orientation for all market participants, strengthens the case for electric mobility, and ensures that used EVs are seen not as a risk, but as a sustainable, trustworthy choice.”
