Sweden's Carla studied 20 European EVs to see which held their battery capacity best over 10,000 miles. At the top of the list, three Korean EVs dominated. You can get one, the Kia EV6, in the US today. It placed third, while Volvo's XC40 Recharge placed fourth. Those may sound like lower finishing spots, but both kept 95.95% and 94.70% of their battery capacity, respectively.The test analyzed around 10,000 batteries from Sweden's electric car market, and was carried out over the course of four years from 2022 to 2026. The study examined how battery health is changing as owners actually use their cars. Typically, batteries lose some of their capacity, and therefore total range, after regular driving. Manufacturers work hard to stave that off, with range being arguably the most important consideration for many EV shoppers.LONDON, ENGLAND - APRIL 16: A Tesla Model 3 and Telsa Energy products including solar panels are displayed during the Everything Electric show at ExCel London on April 16, 2025 in London, England. (Photo by John Keeble/Getty Images)John Keeble/Getty ImagesSome of America's most popular EVs, like the Tesla Model 3 and Volkswagen ID.4, fell outside the top five. The Model 3's battery measured in at 93% of its total capacity, while the VW came in with 92.77% of its total 77 kilowatt hours of capacity.AdvertisementAdvertisementOf the top three models, the Kia e-Niro, Hyundai Kona, and Kia EV6, only the latter is sold in the US. All three retained a battery capacity of more than 95%, with the e-Niro keeping 97.25% of its battery capacity. Battery capacity will matter most for American readers here: plenty of American EVs, like the EV6, use CATL's LFP battery, which showed reduced degradation compared to those from LG and Panasonic. The composition of batteries is nearly as important as the manufacturer, but the overall trend continues to show that new batteries last far longer and hold their charge better than buyers might think.This story was originally published by Men's Journal on Jul 21, 2026, where it first appeared in the News section.
