How to know it's time to replace your EV battery

Electric vehicle batteries are designed for longevity, but they inevitably degrade over time. Unlike internal combustion engines that may show sudden mechanical failure, EV battery degradation is typically a gradual process. Experts suggest that owners should pay close attention to behavioral changes in their vehicles rather than relying solely on the age of the battery. Key warning signs include a noticeable reduction in the vehicle's maximum range on a full charge, longer charging times, or inconsistent power delivery during operation. Modern EVs often include built-in diagnostic tools that monitor battery health, providing data on state-of-health (SoH). While most manufacturers offer long-term warranties covering significant capacity loss, understanding these subtle performance shifts is crucial for maintenance planning. By monitoring these metrics, owners can better manage their vehicle's lifecycle and avoid unexpected service interruptions, ensuring their electric vehicle remains reliable for years to come.
