EV battery health analysis by Arval shows long-term durability well beyond warranty expectations. Based on 8300 battery health certificates issued between March 2023 and November 2024 across eight countries and 30 brands, results reveal an average battery health of 93%. Even after 200,000km, most batteries still retain close to 90% capacity, with 98% of batteries tested remaining above 80%.
This data underpins Arval’s use of battery health certificates when reselling used EVs, helping reassure buyers about performance and longevity – two key concerns in the secondhand EV market.
In the UK, 1400 used EVs have been tested since 2024. Buyers can view battery data via a QR code, which links to a certificate showing usable capacity and estimated range under different conditions.
The battery-health certificates are generated by Moba and Aviloo, both accredited by the Car Remarketing Association Europe. Arval sees this transparency as essential for building trust, supporting EV education and enabling more sustainable purchase decisions.
Gary Burns, remarketing director at Arval UK, said battery health remains critical for both trade and retail buyers. With this initiative, Arval is helping remove key adoption barriers and improve understanding of EV durability. The battery health report reflects real-world data logged by the vehicle itself, not theoretical projections.
