EV Batteries Last Longer Than Previously Feared

Electric vehicle (EV) batteries are demonstrating greater longevity than previously anticipated, with a new study revealing that most used EVs retain approximately 90 percent of their original usable battery capacity after 150,000 kilometers.

Despite a significant increase in global EV sales, partly due to rising fuel prices, concerns about long-term battery durability have remained a primary consideration for consumers contemplating a switch from internal combustion engine vehicles.

Industry norms typically provide battery warranties for eight years or 100,000 miles (160,000 km), obligating manufacturers to replace a battery if its capacity drops below 70 percent.

This latest research offers concrete data on the real-world performance and lifespan of EV batteries, potentially influencing purchasing decisions and mitigating consumer apprehension regarding battery degradation.
