As the electric vehicle (EV) market evolves, concerns about battery health continue to shape decisions for manufacturers and fleet operators alike. Geotab’s latest study provides reassuring news: EV batteries are holding up better than previously expected, retaining an average of 91% of their capacity after five years.

This insight, based on real-world fleet data, underscores incremental improvements in battery technology, offering a promising outlook for fleet managers aiming to extend vehicle lifespans and maximize return on investment.

Clarifying battery degradation myths

Battery degradation has long been a sticking point for those hesitant about EV adoption. While past concerns painted a negative picture, the latest data offers a clearer perspective: degradation is happening at a slower, more manageable rate than anticipated. Geotab’s analysis, showing an average annual degradation rate of just 1.8%, adds to a growing body of evidence dispelling the misconception that EV batteries don’t last.

However, it’s important to note that this data represents one piece of a complex puzzle. Factors like usage patterns, climate, and charging behavior still influence battery performance. And as technology advances, new variables emerge—such as ultra-fast chargers, which may impact battery life in ways we don’t yet fully understand. The key to navigating this complexity is data. Fleet operators should embrace it as a partner in the journey toward electrification. Reliable data will help ensure that fleets make informed decisions as technology evolves.
