Electric vehicles (EVs) are no longer a niche choice; they’re a mainstream leasing option. One of the biggest factors behind this shift? dramatically improved battery confidence. Recent advances in battery health, longevity, range, and charging performance are addressing long-standing concerns about EV reliability, making consumers more comfortable committing to EV leases.
Stronger batteries mean greater peace of mind
A key barrier for prospective EV drivers has long been anxiety around battery degradation. Early EVs saw real-world capacity loss that worried drivers and fleet operators alike. But new data shows this concern is increasingly outdated.
A UK-wide study of over 8,000 electric cars, from the 2025 Battery Performance Index, published by EV battery diagnostics specialist Generational in February 2026, found the average state of health (SoH) for EV batteries sat at around 95%, comfortably above the minimum warranties many manufacturers offer. Even vehicles aged 8 to 12 years still retained a median SoH above 85%, highlighting real-world longevity well beyond typical lease terms.
Similarly, updated industry analyses report that the average annual battery degradation rate for modern EVs is about 2.3%, meaning most electric cars will retain robust battery capacity throughout and beyond a standard 3 to 4 year lease.
What this means for leasing: Customers can now count on their EV batteries to remain reliable and consistent throughout the contract, with minimal loss of range or performance.
Range and charging improvements easing range anxiety
Battery technologies have been steadily improving over the past year too. Manufacturers are designing packs with higher energy density and smarter thermal management systems, helping EVs deliver longer ranges and better performance across varying conditions. Recent data shows modern EVs commonly achieving 250–350 miles per charge, with many premium models comfortably exceeding 400 miles under standard testing cycles.
Charging speeds are rising alongside range. New battery platforms, including high-voltage architectures and advanced cell chemistry, now support rapid charging rates that were once science fiction. Some vehicles can add considerable range in a fraction of the time previously required, thanks to fast-charge improvements that maintain high input even in cold conditions and across different usage patterns.
These gains in range and charging remove one of the psychological hurdles for EV adoption - range anxiety - making electric cars more appealing to drivers considering leasing as a flexible alternative to ownership.
Popular EV leases
With batteries proving their durability and performance improving in leaps and bounds, leasing demand is growing, with certain models leading the way.
According to recent UK leasing data for 2025 and supporting many of the trends we're seeing at Xcite Car Leasing, the Tesla Model 3 was the most leased EV, with other popular choices including the Volkswagen ID.4 and Tesla Model Y. Other models regularly making a splash include the Polestar 2, Volkswagen ID.3, Peugeot e-3008, and a range of BMW EVs such as the i4 and iX1, in addition to the Chinese newcomers such as BYD and Chery.
Leasing uptake is growing faster than ever
- In the UK, drivers who lease are nearly twice as likely to choose an EV compared with the wider driving population.
- The British Vehicle Rental & Leasing Association (BVRLA) reported a 166% year-on-year increase in second-hand EV leases, demonstrating strong growth in both new and used EV lease markets.
This growth reflects not only broader EV adoption, but also improved confidence in battery life and reliability; a crucial consideration for companies and private drivers alike.
What drivers should watch next
Battery chemistry and electric vehicle technology continue to evolve. New concepts like sodium-ion cells - which offer rapid charge times and high durability - are nearing production, promising even faster charging and long life at lower cost.
Meanwhile, standardised battery health reporting and certificates are emerging within the leasing industry, giving lease customers even clearer insight into a car’s condition — another confidence booster that strengthens residual values and supports healthier leasing markets.
Conclusion
As EV batteries get better, so too does the case for leasing them. With robust performance data, longer ranges and improved charging, electric cars are shedding past weaknesses and becoming increasingly reliable, cost-effective leasing options. Whether for EV business leasing or personal use, leasing of electric vehicles is entering a period of accelerating growth, underpinned by growing confidence in the technology itself.
