Aviloo has launched a first-of-its-kind battery warranty — financially backed protection for used EV buyers, built on the same FLASH Test PAD already runs. Here's what it means for buyers and sellers in plain English.
The single biggest barrier to buying a used electric vehicle has always been the battery. You can't see it, you can't feel it degrading, and until recently you had no independent way to verify its condition. Even with an Aviloo certificate telling you the State of Health on the day of testing, some buyers still ask: but what about a year from now?
On 1st June 2026, Aviloo answered that question directly.
The Aviloo Battery Warranty is a financially backed protection product, issued separately from — but based on — the same Aviloo FLASH Test that PAD has been running since launch. Where the certificate describes the battery's condition at the time of the test, the warranty goes a step further: it provides financial protection against future degradation beyond a calculated threshold.
The Aviloo certificate — which PAD issues with every EV and PHEV battery test — describes the battery's condition right now. It's a snapshot: SOH percentage, cell voltages, energy capacity, benchmarking against comparable vehicles. That snapshot is independently verified, timestamped, and accepted by dealers and insurers across Europe.
The warranty is a forward-looking product. It says: if this battery degrades beyond a certain point within the next year, there's a financial safety net. Certificate and warranty are separate documents — but the warranty can only exist because the certificate does. You can't offer financially backed protection without an independently verified baseline measurement. That's precisely why Aviloo built the warranty on top of the FLASH Test rather than the car's own BMS readout.
The used EV market has a trust problem that even a certificate only partially solves. A buyer can accept that the battery is at 87% today — but they're still wondering whether that number will hold up. "What if it drops to 75% by next summer?" That uncertainty has been driving down used EV prices and making buyers hesitant even with a certificate in hand.
The warranty changes the calculation. A buyer who knows they have a year of financial protection against unexpected degradation can commit with genuine confidence — not just a certificate to show the next buyer, but actual coverage if something goes wrong. Aviloo's CEO Marcus Berger put it plainly: for the first time, the battery becomes a reliable selling point rather than a risk factor.
If you're selling a used EV, the certificate already helps you command a higher price — research shows £450–£900 more on average for certified vehicles. The warranty adds another layer: instead of just proving the battery is healthy today, you can offer buyers the assurance of what happens if it isn't tomorrow. That removes the last negotiating angle buyers have on battery condition.
What doesn't change while we wait: PAD's Aviloo FLASH Test is identical to the test that underpins the warranty in every market where it's live. The certificate you receive today is the same independently verified document. When UK availability is confirmed, nothing about the test changes — it's already the right one.
The Aviloo Battery Warranty is part of a broader shift in how used EVs are valued and sold. Aviloo has built the world's largest EV battery diagnostics database over several years — covering over 96% of available brands — and the warranty product draws on that data to calculate individual SoH thresholds per vehicle. It's not a blanket policy; it's a calculated commitment based on what that specific battery model should do over 20,000km.
For the used EV market to mature, this kind of product was inevitable. A car buyer wouldn't purchase a second-hand petrol vehicle without some warranty protection. The same expectation is coming for EVs — and the Aviloo Battery Warranty is the first credible answer to it.
The Aviloo FLASH Test PAD runs is the same test the battery warranty is built on. Book now and the right documentation is already in place when UK warranty availability is confirmed.
