The Battery Health Certificate
Issued by AVILOO — The Global Leader in Battery Diagnostics
Every certificate is issued directly by AVILOO using their TÜV-certified testing methodology. Battery Health Check is an authorised AVILOO partner — we provide the service, AVILOO provides the science. Certificates cannot be edited or modified by anyone, including us. That independence is exactly what makes them trustworthy.
What the Certificate Includes
AVILOO's battery health certificate is a comprehensive, independently verified document that gives buyers complete confidence in the vehicle's battery condition. Each certificate contains:
- State of Health (SoH) — independently calculated percentage, not from the vehicle's BMS
- Cell-level heatmap — visual map showing the condition of each individual cell, with colour-coded severity indicators
- Real-world range — three range metrics: WLTP range, peer-comparison range, and individual range estimate
- Benchmarking — how this battery compares to vehicles of the same make, model, age, and mileage
- QR code — for instant digital verification of certificate authenticity
- AVILOO CERTIFIED seal — awarded when no defects or anomalies are detected
Important Note
The certificate reports the battery's condition at the time of testing. It is not a forecast of future performance, nor is it a mechanical or electrical safety inspection. It provides an accurate, independently verified snapshot of battery health at the point of sale.
Why It Matters
88% of used EV buyers want an independent battery health assessment before purchase. An AVILOO certificate — the only TÜV-certified battery test in the world — gives them exactly that.
Because certificates are issued directly by AVILOO and cannot be altered, buyers know the results are genuine. No dealer can inflate the numbers. No middleman can adjust the findings. That is the trust your customers are looking for.
Legal Protection
The certificate serves as auditable evidence of battery condition at point of sale. Under the Consumer Rights Act 2015, dealers face a reversed burden of proof in the first six months — meaning defects are presumed to have been present at delivery unless proven otherwise.
A pre-sale AVILOO battery health certificate is your proof.
