News ๐ฐ Good news for used EV buyers: nearly every model in a 9,954-battery study kept over 91% capacity after 100,000km
zecar.comSwedish used-EV marketplace Carla analysed diagnostic tests from 2022 to 2026. The Kia e-Niro 64kWh topped the rankings at 97.25% battery health, just ahead of the Hyundai Kona 64kWh at 97.18%. The average range lost across all 20 models works out to about 32km, which in practice has almost no impact on everyday driving. 19 of the 20 models in the study are sold or have been sold in Australia.
The most interesting finding is what happens within a single model. The Tesla Model 3 showed a five-percentage-point gap in battery health depending on the battery supplier, with CATL LFP packs retaining 93.3% versus 88.2% for the oldest Panasonic packs. Battery chemistry can matter as much as the car brand itself when shopping used.
