New Study Shows Modern EV Batteries Retain 95% of Range After Five Years

Electric vehicle batteries are significantly more durable than popular perception suggests, according to new data from battery analytics company Recurrent. The study, based on more than 30,000 connected vehicles, found that the average EV retains approximately 95% of its original driving range after five years on the road, and 97% after three years.

The findings challenge one of the most persistent barriers to EV adoption: the fear that battery degradation will render an electric car impractical within a few years. Recurrent’s data shows that scenario is extremely rare, with only 1.5% of batteries in its study requiring replacement.

“Range cliff fear isn’t showing up in our data,” Recurrent’s research team reported.

How Automakers Maintain Range

The study’s results surprised even Recurrent’s researchers. More than two-thirds of the electric vehicles studied showed range figures above their original EPA estimates at the three-year mark, a finding the company said was unexpected.

Recurrent attributes the stability to a combination of engineering strategies. Some manufacturers hold back a portion of battery capacity at launch, then gradually unlock it through over-the-air software updates. Adjustments to range estimation algorithms also help maintain consistent figures over time.

Several automakers showed no “apparent” range loss whatsoever across the years analyzed, including Cadillac, Ford, Hyundai, Mercedes-Benz, and Rivian. Industry-wide, Geotab’s parallel analysis of 22,700 vehicles found an average annual capacity loss of approximately 2.3%, consistent with Recurrent’s five-year findings.

What Degrades Batteries

Heat, high voltage, and extreme states of charge remain the primary drivers of battery degradation, according to Recurrent’s research. Vehicles regularly fast-charged in hot climates showed more capacity loss than those charged slowly in temperate conditions.

The study noted that lithium-iron-phosphate (LFP) battery chemistries, increasingly popular in entry-level EVs, can be charged to 100% daily without accelerated degradation, unlike older nickel-cobalt-manganese (NCM) chemistries that benefit from being kept between 20% and 80% for daily use.

A 2026-model-year EV rated at 523 kilometres (approximately 325 miles) of range is expected to deliver roughly 497 kilometres (approximately 309 miles) by 2031, according to Recurrent’s projections, a loss of about 26 kilometres (approximately 16 miles) over five years.
