A lot of people assume EV batteries lose a large amount of capacity quickly, and that buying a used EV automatically means getting a worn-out battery.
Real-world data tells a different story.
An analysis by Swedish used-car platform Carla included 9,953 EV battery tests conducted between 2022 and 2026, using diagnostics from AVILOO, a company specializing in battery health testing.
The striking result? 94% of the vehicles tested still had more than 90% battery health, while more than half retained at least 95%. Only 13 vehicles out of nearly 10,000 tests recorded battery health below 80%.
Looking specifically at EVs that had traveled more than 100,000 km (62,000 miles), the published results for 20 models ranged from roughly 91.8% to 97.3% of their original capacity.
Some of the results included:
Kia e-Niro: 97.25%
Hyundai Kona Electric: 97.18%
Kia EV6: 95.95%
Volvo XC40 Recharge: 94.70%
Polestar 2: 94.35%
Tesla Model 3 LFP: 93.34%
Volkswagen ID.3: 91.79%
Put simply, an EV with more than 62,000 miles on the odometer may still have a battery far from the "end of its life." Some vehicles in this dataset were still retaining roughly 92% to 97% of their original capacity.⚡🚗
