Worried that EV batteries won’t last? A new study suggests those fears are outdated. According to vehicle telematics company Geotab, modern electric vehicle batteries can last up to 20 years, significantly longer than the average lifespan of a gasoline-powered vehicle in the U.S., which currently sits at 14 years. The study, which analyzed over 10,000 EVs, shows that EV batteries degrade at an average rate of just 1.8% per year, meaning most drivers can expect to retain over 64% of their original driving range even after two decades on the road.

Importantly, battery failure in EVs is extremely rare, with recent data showing a failure rate of less than 0.5% in electric vehicles built over the past 10 years. This suggests that EV battery reliability is no longer a question mark but a proven strength. While some degradation is inevitable—especially during the early years and in hotter climates—modern battery thermal management systems do an excellent job of protecting longevity.

To further maximize battery lifespan, drivers are encouraged to use slower charging methods like Level 1 or Level 2, avoid extreme heat during charging, and maintain the battery’s state of charge between 20% and 80%, especially for vehicles using nickel-based chemistries like NMC or NCM. Even lithium iron phosphate (LFP) batteries, which are more durable in this regard, can benefit from thoughtful charging habits.

Ultimately, this new data gives prospective EV buyers more confidence in the long-term value of electric vehicles. With lower operating costs, fewer maintenance concerns, and now a confirmed long-term battery performance outlook, EVs are proving to be a smart, sustainable choice for drivers looking to make the switch from gasoline to electric.
