Powering the future of transportation.
EV batteries are designed to last longer than the vehicle it powers, can have a second-life supporting energy storage, and can be recycled into new batteries.
EVs are incredibly efficient compared to gas-powered vehicles. Much of this is due to the battery.
Studies show that internal combustion engine (ICE) vehicles lose about 80% of the original fuel energy as heat. Electric vehicles, on the other hand, only lose about 11% of their original energy when propelling the vehicle.
A study by Yale University highlights that even an EV running on electricity generated from fossil fuels (like coal or natural gas) will be more energy efficient compared to an ICE vehicle.
All of this is in short thanks to the amazing battery technologies that power each EV.
Will I need to replace my EV’s battery?
Batteries are designed to support the EV it powers for 15-20 years, and are unlikely to need to be replaced. In fact, most EV batteries will be repurposed for other uses after the vehicle is retired—such as for energy storage or for recycled material content for future batteries. Recurrent has long studied the age of EV batteries and has published some pretty stark findings: across all 30,000 surveyed vehicles (from 2011 onwards) less than 4% of all EV batteries have been replaced. For modern EVs, on sale since 2022, the replacement rate is a lowly 0.3%.
Even while EV battery replacement rates for newer cars have remained low, it may ease consumer’s concerns that all automakers have lengthy battery warranties for electric cars. These warranties cover the driver for battery replacements if necessary: the federal minimum warranty is 8 years or 100,000 miles, though some manufacturers provide stronger terms. This is significantly stronger than the average powertrain warranty for a gas-powered vehicle (5 years and 60,000 miles).

Long Lifespan
Batteries often last 15–20 years in everyday use.
Reliable Performance
Replacement rates are very low across all models.
Sustainable Lifecycle
Retired batteries can be reused, then fully recycled.
Do EV batteries lose range over time? How much?
The battery’s efficiency will deteriorate over time and vary by battery design and manufacturer. Recent analysis by Recurrent suggests that EV battery degradation has been minimal and that the remaining range of EVs after 150,000 miles is gettingbetter with newer models (an improvement of around 10%) as EV battery technology has continued to improve.
That said, there are a few things you can do to limit battery degradation over time. For example, keeping your battery charged between 25-75% has been shown to protect it. Avoiding parking for extended times in extreme heat is also a good practice.
What happens to the battery when my EV is retired?
It all depends on the state of the battery.
When EV batteries degrade to about 70–80 percent of their original capacity, they may no longer be optimal for use in a vehicle, but they still retain significant energy storage potential. Rather than being immediately recycled these EV batteries can be repurposed for secondary applications, most notably battery energy storage systems (BESS). Storage is now being increasingly utilized in the U.S.
Once these batteries reach their end of life, they can be transferred over to advanced battery recyclers for the purposes of critical mineral reclamation. While the recycling process varies depending on the specific EV battery chemistry, recycling allows for the recovery and refinement of critical minerals – so that they can be reused in a new EV battery and begin the cycle anew. By 2035, domestic U.S. battery recycling could recover enough material to supply up to 1.55 million passenger EVs annually—equivalent to nearly 10 percent of U.S. passenger vehicle sales in 2025.
ZETA published a holistic report in August 2025 highlighting the emergence of the EV battery recycling industry entitled, “Closing the Loop: Strategies for Electric Vehicle Battery Management and Critical Materials Recovery.”
Battery recycling should be a strategic pillar of U.S. industrial policy that reduces dependence on adversary-controlled critical mineral supply chains while supporting energy security, economic competitiveness, and national defense.
Advanced battery recyclers are scaling rapidly, driven by market forces—over 20 facilities have been announced or are operational across the U.S., supported by more than $9.65 billion in private investment.
The majority of end-of-life EV battery packs are currently being exported to China. By scaling up domestic EV battery recycling, we can anchor more critical mineral value here at home and improve supply chains with allied trade partners.
A market-based approach—backed by clear policy guardrails—is essential. Federal and state leaders should adopt flexible, performance-based regulations, provide incentives for recycled content, and invest in infrastructure and R&D to accelerate recovery capacity
Although battery recycling is gaining momentum, challenges still remain, such as transportation barriers, cost responsibilities, regulatory oversight, and a lack of consistent collection and labeling standards. Clearer federal guidance and stronger industry coordination will be key to building a cohesive national battery recycling strategy.
