How Much Does It Cost to Charge an Electric Car? Home vs. Public vs. Gas (2026)
Charging an EV at home costs about 6 cents a mile on average, less than half the cost of gas. Here's the math for home, public charging and every budget.
The average EV keeps about 95% of its range after five years, and replacements are rare. Battery life, warranties and how to make yours last.

"What happens when the battery dies?" It's the biggest worry for people considering an EV. In a 2026 AAA survey, 56% of people unlikely to buy an EV named battery repair or replacement costs as their top reason. The real-world data tells a much better story. Modern EV batteries are lasting far longer than most people expect, and very few ever need to be replaced.
Battery-health company Recurrent tracks thousands of EVs on the road. Its data shows the average EV keeps about 97% of its original range after three years and 95% after five. A 2026 EV with 325 miles of range would still have around 309 miles after five years.
Fleet-tracking company Geotab, which studied more than 22,700 vehicles, found average battery degradation of about 2.3% per year. Degradation also isn't a straight line. Batteries typically lose a few percent early, then level off and decline slowly for years.
And replacements are rare. Recurrent reports a battery replacement rate of just 0.3% for EVs from model year 2022 onward, and most of those were covered by warranty or recalls, not normal wear.
US federal rules require EV battery warranties of at least 8 years or 100,000 miles. Many automakers also guarantee the battery will keep a minimum capacity, usually 70%, during the warranty. Some go further. For example, Tesla's Long Range and Performance models carry an 8-year/120,000-mile battery warranty with 70% retention. Check your specific model's warranty booklet for details.
| Factor | Effect | What to do |
|---|---|---|
| Sitting at 100% for long periods | Stresses most NMC/NCA batteries | Charge to about 80–90% for daily driving, unless your car has an LFP battery |
| Very frequent DC fast charging | More heat and stress | Use home charging day to day; fast charge on trips |
| Extreme heat | Speeds up chemical aging | Park in shade or a garage in hot climates when possible |
| Sitting near 0% for long periods | Can damage cells | Avoid leaving the car nearly empty for days |
The good news: modern EVs have sophisticated battery management systems that control temperature and charging speed automatically. Normal driving and charging habits are fine. (See our guide: Should you charge to 80% or 100%?)
If a battery does need replacement outside of warranty, a full pack can cost anywhere from several thousand dollars to over $15,000 depending on the vehicle. But a full replacement is often not needed. Many repairs fix a single module or component for much less, and battery prices have fallen sharply over the past decade. For most owners, the battery will outlast the years they keep the car.
Even when an EV battery drops to 70–80% capacity, it still holds a lot of energy. Many are reused for home or grid energy storage, and others are recycled. Companies like Redwood Materials recover lithium, nickel, cobalt and copper to make new batteries.
How long do electric car batteries last?
Most are expected to last 15–20 years and well over 150,000 miles. Real-world data shows the average EV keeps about 95% of its range after 5 years.
How often do EV batteries need to be replaced?
Rarely. Only about 0.3% of 2022-and-newer EVs have needed a battery replacement, according to Recurrent.
What is the warranty on an EV battery?
At least 8 years or 100,000 miles in the US, often with a guaranteed minimum capacity of 70%.
Does fast charging ruin the battery?
No. Occasional fast charging has a small effect. Charging mostly at home is gentler on the battery over time.
The bottom line: The fear of a dead EV battery after a few years doesn't match the data. The average EV keeps about 95% of its range after five years, replacements are rare, and every new EV comes with at least an 8-year battery warranty. Charge sensibly, and your battery will likely outlast your ownership.

Charging an EV at home costs about 6 cents a mile on average, less than half the cost of gas. Here's the math for home, public charging and every budget.
