For years, the loudest argument against buying an electric vehicle wasn’t range anxiety or charging times — it was fear of the battery. Would that expensive pack survive more than a few years, or would it die an early, wallet-crushing death long before the rest of the car gave up? Real-world data, according to a report from The Wall Street Journal, is now quietly demolishing that worry.
Take Richard Symons, a UK-based used EV dealer whose five-year-old Tesla Model 3 has already racked up 247,000 miles — and still handles long-distance trips without breaking a sweat. His car isn’t a freak outlier. It’s increasingly the norm.
Battery analytics firm Recurrent estimates that after five years of ownership, the average EV retains up to 95 percent of its original driving range. That’s well above what early adopters dared hope for. Credit goes to smarter battery chemistry, better thermal management, and battery-management software that babies the cells to keep long-term wear in check.
The repair numbers are even more telling. Roughly one in 12 EVs built between 2011 and 2016 eventually needed a battery replacement. For models built from 2022 onward, that figure has collapsed to just 0.3 percent. The original Nissan Leaf — which lacked any modern battery cooling — is a poster child for the old, degradation-prone era that’s now firmly behind us.
Consumer perception, however, hasn’t caught up. A 2025 AutoPacific survey found that fear of pricey battery replacement remains the top reason prospective buyers steer clear of EVs. As Edmunds’ head of insights Jessica Caldwell told the Journal, plenty of shoppers still eye EV batteries with deep suspicion, reliability data be damned.
That said, batteries aren’t invincible. How you charge matters a lot:
- Frequent high-power DC fast charging takes a toll — Geotab data shows those batteries retain about 89.7 percent of capacity after several years.
- Batteries relying mostly on lower-frequency fast charging held onto 94.9 percent over the same period.
Regularly charging to 100 percent, leaving a pack fully discharged for long stretches, and operating in extreme temperatures all chip away at battery health too.
Replacement costs remain no joke — anywhere from roughly US$5,000 to US$16,000 outside warranty, depending on the automaker. The good news is that many manufacturers now design packs so individual modules can be repaired rather than swapping the whole thing, which trims long-term ownership costs.
The timing is awkward: US EV sales have slowed in 2026 following changes to government incentives. But analysts expect the long-term climb to resume. AlixPartners forecasts EVs will reach 11 percent of new US vehicle sales by 2030, with the global figure approaching 25 percent by the end of the decade. As more high-mileage EVs quietly clock the miles, one of the industry’s biggest bogeymen may finally be running out of charge.
