New Research Confirms That Modern EVs Rarely Need Battery Replacements

One of the most persistent concerns surrounding electric vehicles (EVs) is the fear of costly battery replacements. Whether from skeptical buyers or critics of EV technology, the worry remains the same: what happens when the battery dies? This concern often leads people to believe that owning an electric car might eventually destroy their finances.

However, new research from Recurrent, a company that specializes in tracking EV battery health, shows that these fears are largely outdated. According to InsideEVs, Recurrent’s latest findings confirm that modern EV batteries almost never need replacement.

Battery Replacements Are Far Less Common Than People Think

Liz Najman, Recurrent’s Director of Market Insights, explained that early-generation EVs did indeed face more battery issues. But in today’s EVs, those problems are extremely rare.

“You will rarely need to get a battery replaced,” Najman said, noting that while occasional defects can occur, most EV batteries perform reliably once the vehicle is in regular operation.

Recurrent’s data backs this up. When excluding major recall cases caused by manufacturing defects — such as the well-known Chevrolet Bolt and Hyundai Kona battery recalls — the overall EV battery replacement rate is only about 4%.

Replacement Rates Have Dropped Sharply Over Generations

EV technology has evolved rapidly, and battery replacement rates reflect this progress:

• First-generation EVs (2011–2016): 8.5% replacement rate
• Second-generation EVs (2017–2021): 2% replacement rate
• Third-generation EVs (2022 onward): 0.3% replacement rate

These numbers show a dramatic decline in replacements, indicating significant improvements in battery engineering.

Why Early EV Batteries Had More Issues?

Part of the higher failure rate in older EVs comes down to age — early 2010s models have simply been on the road longer. However, technology was also a major factor.

For example, the original Nissan Leaf lacked an active battery cooling system. Without proper temperature control, batteries degrade faster, especially in hot climates. Modern EVs, by contrast, are equipped with:

• Advanced liquid cooling systems
• Smarter and more efficient battery management systems (BMS)
• Better thermal controls and battery chemistry
• More durable cell designs

These advancements allow modern EV batteries to maintain their health over much longer periods.

Modern EV Batteries Are Built to Last

Today’s electric vehicles are engineered with longevity in mind. Manufacturers design their batteries to last for hundreds of thousands of kilometers, and real-world data increasingly shows that EV batteries often outlast the vehicle itself.

The myth of frequent, expensive battery replacements is gradually fading as research and historical data continue to prove otherwise. For buyers considering an electric vehicle, the message is clear: modern EV batteries are more durable and reliable than ever before.
