A recent study by Recurrent has shown that battery replacements in EVs remain remarkably rare. The study, which examined data from over 20,000 electric vehicles spanning model years 2011 to 2024, found that only 2.5% of EV battery packs have been replaced to date. This figure excludes high-profile recalls, such as General Motors’ issues with the Chevy Bolt EV.
One of the main arguments against electric vehicles is the high cost of battery replacements, which can be as much as 50% of a vehicle’s value. Critics often cite this as a reason for considering EVs as less viable compared to traditional combustion-powered cars. However, Recurrent’s study provides a counter-narrative. The study indicates that battery replacements are infrequent, suggesting that concerns over the cost and frequency of battery replacements may be overstated.
The study acknowledges the occurrence of battery recalls, particularly from manufacturers like General Motors and Hyundai. Yet, these recalls have not significantly impacted the overall replacement rate. Notably, most battery replacements have been managed under warranty, minimizing financial burdens on consumers. For instance, a Hummer EV owner shared their experience where General Motors replaced their battery twice, providing a new battery, a loaner vehicle, and $250 for the old battery, all at no cost to the owner.
“GM called and asked if they could have my battery for an engineering study. They offered me $250.00, the new battery, and a loaner vehicle. Dealer turned it around in one day, as this was the second time they replaced my battery. Win win for everyone,” the Hummer EV owner noted.
Recurrent’s findings highlight a clear distinction in replacement rates between older and newer EV models. Vehicles produced before 2015 have a replacement rate of 13%, while those manufactured from 2016 onwards have a replacement rate of less than 1%. This disparity is attributed to advancements in battery technology, including improved battery chemistries and more effective thermal management systems.
As per Recurrent’s findings: “Across all years and models, outside of big recalls, only 2.5% have been replaced. This increase from last year is entirely due to older cars. For cars older than 2015, replacement rates are 13%, but under 1% for cars from 2016 and newer.”

The study points out that newer EVs are equipped with batteries that have better thermal management systems and more robust chemistries. These advancements contribute to a longer lifespan and reduced degradation of the batteries. Furthermore, the average battery size has increased by 122% between 2015 and 2022, providing newer EVs with larger capacities and greater resilience against capacity loss.
The findings of the study offer reassurance to current and prospective EV owners. The low replacement rates suggest that the perceived high cost and frequency of battery replacements may not be as significant a concern, especially for newer models. This could encourage more consumers to consider purchasing used EVs without worrying excessively about battery health.
While the study presents promising data, challenges remain in the EV sector. The high upfront cost of EV batteries and the ongoing need for innovation in battery technology are notable hurdles. However, the positive trends in battery longevity and the decreasing replacement rates underscore the progress being made.

Studies like the one conducted by Recurrent are crucial for informing potential EV buyers. They provide valuable insights into the realities of EV maintenance and ownership, helping to dispel misconceptions and build confidence in the market. As EV adoption continues to rise, such research will play an essential role in shaping consumer perceptions and driving the transition to electric mobility.
The study also sheds light on the future of EV battery technology. Continuous improvements in battery chemistry and thermal management are expected to bring incremental enhancements. Additionally, breakthroughs in battery technology, such as the development of solid-state batteries, could revolutionize the industry by providing significant leaps in performance and longevity.
