A long-running worry still hangs over electric vehicles. Many drivers fear the battery will fail after only a few years and saddle them with huge repair costs.
In an online exchange, EV owners argued that the fear may come less from cars than from the rechargeable devices people know best.
Here's what to know
The discussion unfolded on Reddit, where the original poster summed up the myth.
"It's that the battery dies after X amount of years and leaves you with a $15-20k bill," they noted.
The poster also cited consumer surveys they said found 26% to 56% of car buyers believe that idea, while noting that full battery swaps happen in just 2.5% of EVs.
They argued that most EVs carry battery coverage lasting at least eight years or 100,000 miles, exceeding a typical gas powertrain warranty, and said packs generally last around eight to 15 years, with range fading over time instead of failing all at once.

As for why the myth persists, replies repeatedly cited phone battery experience.
"Most peoples' most important interaction with a chargeable product is their phone," they asserted. "And all of us have had phones where, after a year, the battery is down to 83% and it drains quickly compared to the beginning."
Early Nissan Leafs were also cited as a big reason the belief stuck. Commenters argued those first-generation models became associated with faster battery degradation, helping create the impression that EV packs wear out quickly.
More background
The thread also included people who said they once believed the warning themselves. One commenter, who described himself as a "local yokel and weekend wrench turner," said he had long seen EVs as "a financial trap" because a degraded battery seemed likely to make the car too expensive to keep.
He said that view changed after looking more closely at Bolt prices, fuel expenses, and battery failure rates. After reading up and taking a test drive, he wrote that he "went right to the bank and got the check."
Not everyone in the thread framed the issue as a simple rumor. One commenter argued that shoppers still don't get battery-life information in a form that is easy to understand, and said a warranty can't easily fill that role.
Commenters also said buyers often hold EVs to a different standard than gas cars, tolerating common maintenance issues more readily than they might accept future battery problems.
What can be done?
Several commenters said the conversation will change only when manufacturers make long-lived EVs more visible.
"Start advertising owners with EVs that have 200,000 miles on the original battery pack, and that will change the discussion," one declared.
They also pointed to improvements in vehicle design. The early Leaf kept surfacing as the cautionary example, while newer EV batteries held up much better.
As older EVs stay on the road and more buyers test-drive lower-cost models, more people may be able to compare rumor with firsthand experience.
One commenter captured that shift neatly, saying their phone had them worried about EV batteries: "It definitely did for me before I got an EV and realized it was an unfounded fear."
Where can I learn more?
Battery life and replacement costs remain two of the biggest sticking points for EV shoppers.
• A used Tesla Model Y left one owner fearing a $16,000 battery bill.
• In Northern Europe, wary shoppers heard owners say the battery outlasts the car.
• A Tesla Model 3 hit 250,000 miles, with battery loss and repairs closely tracked.
