Mercedes EQA, Hyundai IONIQ 5, and BMW i4 show best battery retention
A comprehensive analysis of over 500,000 battery tests reveals which electric vehicles maintain the healthiest battery packs over time.
A sweeping independent analysis of more than half a million battery tests has identified which electric vehicles best preserve their power storage systems. The research, described as the largest of its kind, tracked battery health across numerous models to establish clear performance rankings in this critical category for EV owners and buyers.
The Mercedes EQA, Hyundai IONIQ 5, and BMW i4 emerged at the top of the rankings, outperforming their competitors in maintaining battery capacity over the vehicles' lifespans. These three models demonstrated notably stronger retention of their original battery performance compared to other electric cars examined in the study.
The findings provide valuable data for consumers evaluating which electric vehicles offer the most durable battery systems, an increasingly important consideration as the secondhand EV market grows and battery longevity becomes a primary concern for used-car shoppers.
