Tesla Battery Replacement Cost (2026): Real Prices by Model

5 min readBy the FSDClarity team

Replacing a Tesla's main battery pack out of warranty typically costs about $10,000–$16,000 for a Model 3 or Model Y and $12,000–$21,000 for a Model S or Model X, installed. But most owners never pay it: every Tesla has an 8-year battery warranty, and packs usually outlast it. If only part of the pack has failed, an independent shop may fix it for $2,000–$7,000 instead.

Pack replacement, out of warranty

$12,000 – $16,000

Battery warranty status

Likely covered

Your Model 3 Long Range is inside Tesla's 8-year / 120,000-mile Battery & Drive Unit warranty. If the pack fails or drops below 70% capacity, Tesla should repair or replace it at no cost.

Cheaper options than a full new pack

  • Module repair at an independent EV shop: about $2,000–$7,000, when only one module has failed.
  • Refurbished or used packs from EV specialists usually cost less than new, with a shorter warranty.
  • The 12V / low-voltage battery is a separate, small battery — usually about $200–$400 installed, not thousands.

Tesla doesn't publish battery prices, so these are installed estimates from 2026 third-party pricing and owner reports. A written quote from Tesla Service for your VIN is the only exact number.

ModelTypical out-of-warranty replacementBattery warranty

Model 3 Long Range / Performanceabout $12,000–$16,0008 years / 120,000 miles
Model Y RWDabout $10,000–$14,5008 years / 100,000 miles

Model Xabout $15,000–$21,0008 years / 150,000 miles

Why the range is wide: pack size, whether Tesla installs a new or remanufactured pack, labor rates in your area, and whether other parts such as coolant lines or the drive unit need work at the same time. Older Model S and Model X packs can push toward the top of the range.

High-voltage pack vs the 12V battery

Two different batteries get mixed up in searches:

  • The high-voltage pack is the big battery under the floor that drives the car. That's the $10,000+ part.
  • The 12V or low-voltage battery runs the computers, locks and lights, like the small battery in a gas car. Newer Teslas use a lithium-ion low-voltage battery. Replacing it typically costs about $200–$400 with Tesla Service.

If your Tesla shows a "12V battery needs service" alert, that's the small battery — not a pack failure.

Tesla vs independent repair shops

OptionTypical costGood to know
Tesla Service, full pack$10,000–$21,000Tesla-backed parts warranty; often a remanufactured pack
Independent EV shop, module repair$2,000–$7,000Only when the fault is in one module
Refurbished or used packLess than newShorter warranty; quality varies by supplier

Independent EV specialists can diagnose a pack and replace a single failed module, which is far cheaper than a whole pack. The catch: not every fault can be fixed that way, and a third-party repair may affect any remaining Tesla warranty. Get a diagnosis report in writing first.

What the 8-year warranty covers

Every Tesla has a Battery & Drive Unit Limited Warranty for 8 years, with a mileage cap that depends on the model (see the table above). Within that period, Tesla repairs or replaces the pack if it fails or drops below 70% of its original capacity.

Important details:

  • The warranty starts on the car's original delivery date, and transfers to new owners automatically.
  • Damage from a crash, flooding, fire or misuse isn't covered — that's an insurance matter.
  • Normal capacity loss above 70% isn't a defect.

How often do Tesla batteries actually fail?

Rarely before the warranty ends. Tesla reports that Model S and Model X packs keep about 88% of their original capacity after 200,000 miles on average, and owner data points the same way. Most cars will be retired for other reasons long before the pack needs replacing.

When replacement isn't worth it

On an older, high-mileage Tesla worth $12,000, a $14,000 battery doesn't add up. In that case, consider:

  1. A module repair at an independent EV shop, if the diagnosis allows.
  2. A refurbished pack, accepting a shorter warranty.
  3. Selling the car as-is to a buyer or shop that specializes in EV repairs.

On a newer car in good condition, replacing the pack usually makes sense — it can add years of life and resale value.

Does insurance cover battery replacement?

Only when the damage comes from a covered event, such as a collision, road debris puncturing the pack, or flooding under comprehensive coverage. Insurance doesn't pay for normal wear or age-related failure; that's what the warranty is for.

Frequently asked questions

How much does a Tesla Model 3 battery cost to replace?

About $10,000–$14,500 for an RWD and $12,000–$16,000 for a Long Range or Performance, installed, out of warranty.

How much is a Tesla Model Y battery replacement?

About $10,000–$14,500 for an RWD and $11,000–$16,000 for a Long Range or Performance, installed.

How long does a Tesla battery last?

Typically well beyond its 8-year warranty — Tesla's data shows about 12% capacity loss after 200,000 miles on Model S and X.

Can you replace just part of a Tesla battery?

Sometimes. Independent EV shops can replace a single failed module for $2,000–$7,000 when the fault allows. Tesla usually replaces the full pack.

The bottom line

Out of warranty, budget $10,000–$16,000 for a Model 3 or Model Y battery and more for a Model S or X — but check the warranty first, because most Teslas on the road are still covered. Run your car through the Battery Replacement Cost Estimator to see where you stand.
