• Electric Vehicles EV batteries EVs ev range Most EV batteries outlast their cars, real-world data shows A new large‑scale UK dataset suggests EV batteries are holding up far better than many skeptics expected. • London‑based EV battery diagnostics companyGenerationalanalyzed more than 8,000 battery tests across 36 automakers and found the average EV battery State of Health (SoH) is 95.15% of original capacity. • The results cover passenger cars and light commercial vehicles ranging from brand‑new to 12 years old and with anywhere from zero to more than 160,000 miles on the odometer. • That’s a strong real‑world data point as debates about battery lifespan, resale value, and long‑term ownership costs continue to shape consumer confidence in used EVs. • What EV battery health data shows Across the entire sample, battery health remained high even as vehicles aged: Average State of Health across all vehicles: 95.15% 4‑5‑year‑old EVs: median 93.53% 8‑9‑year‑old EVs: median 85% High‑mileage EVs (100,000+ miles): frequently 88-95% SoH Even older vehicles rarely approached typical manufacturer warranty coverage, which is usually around 70% of the original capacity after eight years or 100,000 miles. • The dataset also shows a widening performance gap as vehicles age.
