How Long Do Electric Car Batteries Actually Last? (2026 Real-World Data)
EV Battery Degradation: How Much Capacity Do Electric Cars Really Lose After 5 Years? If you're considering buying an electric vehicle—new or used—there is one major fear that often holds buyers back: "Will the battery die in a few years and cost a fortune to replace?" Because smartphones lose noticeable battery health after just two years, it's natural to assume electric cars suffer the exact same fate. But automotive battery packs are engineered with liquid thermal management, complex battery management systems (BMS), and protective software buffers. At Technically.gr , we analyzed recent fleet data and large-scale battery health studies to uncover the real numbers behind EV battery degradation after five years of daily driving. What Is EV Battery Degradation? Battery degradation refers to the gradual loss of a battery's capacity to hold an electric charge over time. It is measured by State of Health (SoH) : 100% SoH: A brand-new battery storing its maximum f...
