How long does a Tesla battery last?
300,000 to 500,000 miles, typically.
Most Tesla batteries outlast the car itself, with minimal degradation over the first 150,000 miles. What settles it: how you charge and where you live.

What's your charging setup?
Why?
Degradation is slow Tesla batteries lose about 5% capacity in the first 50,000 miles, then level off.
Heat is the enemy Hot climates and frequent fast charging accelerate aging more than mileage.
Software helps Battery management keeps the pack healthy, so most packs outlast the car.
Exact lifespan varies by model, year, and how the car is used; newer chemistries may do better.
If your situation is different
What's your charging setup: Home L2. Closer to 500,000 miles. Slow, regular charging is gentlest on the pack.
What's your charging setup: Supercharger. Closer to 300,000 miles. Frequent fast charging adds heat and wear.
What's your charging setup: Mixed. Around 400,000 miles. A balance of both is typical and fine.
Who is a Tesla battery right for?
Right for
- Daily commuters with home charging
- Drivers in mild climates
- Owners keeping a car past 100,000 miles
- People who rarely use Superchargers
Wrong for
- Renters without a dedicated outlet
- Drivers in extreme heat with no garage
- Road-trippers who rely on fast charging
- Anyone expecting a 20-year lifespan
What does a Tesla battery cost in 2026?
| Figure | Value | Why it matters |
|---|---|---|
| Battery replacement cost | $5,000 to $20,000, 2026 | A new pack is the biggest single expense, often more than the car's resale value. |
| Warranty coverage | 8 years or 100,000 to 150,000 miles, 2026 | Tesla covers defects and excessive degradation during this period. |
| Capacity after 150,000 miles | About 90% of original, 2026 | Typical degradation levels off after the initial 5% drop. |
| Supercharger cost per mile | $0.10 to $0.25 per mile, 2026 | Fast charging is convenient but adds wear and costs more than home charging. |
What's the biggest Tesla battery mistake?
The biggest mistake is treating the battery like a fuel tank and running it to near-empty before charging. That habit, plus frequent Supercharging, accelerates degradation. Instead, keep the charge between 20% and 80% for daily driving and save full charges for trips.
How do you decide if a Tesla battery is worth it?
- Check your daily commute and whether you can install a home charger.
- Look up your model's warranty end date and miles.
- Estimate how often you'd use Superchargers versus home charging.
- Decide: if you can charge at home and drive under 100 miles a day, the battery will outlast the car.

How much does a used Tesla with high mileage go for?
High-mileage used Teslas run $15K to $30K. That's for a Model 3 or Y with 100K+ miles. Older Model S or X with similar miles can drop under $15K, but battery health matters more than the odometer.
