Tesla may repair or replace your High Voltage battery at no charge if it develops a covered defect—or falls below its applicable capacity guarantee—before the warranty expires. But fewer miles on the dashboard does not automatically qualify you for a replacement, and an eight-year warranty can end earlier when you reach its mileage limit.
Before approving an expensive repair, check three things: which battery has the problem, the warranty attached to your exact vehicle, and Tesla’s diagnosis. Those details matter more than a general statement that “Tesla batteries have an eight-year warranty.”

How Long Is the Tesla Battery Warranty?
Tesla’s current U.S. warranty summary lists the following limits. Every period ends when either the time limit or mileage limit is reached, whichever comes first.
| Model or Configuration | Battery and Drive Unit Coverage | Minimum Capacity Retention |
|---|---|---|
| Model S, Model X and Cybertruck | 8 years or 150,000 miles | 70% |
| Model 3 RWD; Model Y RWD and AWD configurations listed in Tesla’s 100,000-mile category | 8 years or 100,000 miles | 70% |
| Model 3 Premium RWD, Premium AWD and Performance AWD | 8 years or 120,000 miles | 70% |
| Model Y Premium RWD, Premium AWD, Performance AWD and Model Y L Premium Launch Series | 8 years or 120,000 miles | 70% |

Buying or owning an older Tesla? Use the warranty issued with that vehicle. Older documents may use names such as Standard Range, Standard Range Plus or Long Range, and some earlier Model S and Model X warranties differ substantially. A current chart does not rewrite an older car’s contract.
Check Your Actual Coverage in the Tesla App
Open the Tesla app, select Specs & Warranty, then open the Warranty tab. Review the dates and mileage limits alongside your original warranty documents.
For example, a vehicle with an eight-year/100,000-mile battery warranty can run out of coverage after five years if it reaches the mileage limit. Being younger than eight years is not enough.
When Will Tesla Replace a Battery for Free?
There are two important routes to a covered battery remedy:
- A covered malfunction or defect: The battery develops a qualifying problem during the applicable coverage period.
- A qualifying capacity loss: Battery capacity falls below the minimum guaranteed by that vehicle’s warranty during the coverage period.
A defective battery does not have to fall below 70% capacity before it can qualify. A battery can retain plenty of capacity and still develop a covered fault that prevents normal charging or operation.
However, an approved claim does not necessarily mean a complete new pack. Tesla determines whether repair or replacement is appropriate.
The question to ask: “What component failed, is the failure covered, and what repair are you proposing?” Asking only for a new battery can skip the diagnosis that determines the answer.
Which Tesla Battery Has Failed?
The High Voltage battery stores the energy used to drive the car. The smaller low-voltage battery supports electronics and vehicle controls. Depending on the model and production date, owners may refer to that smaller battery as a 12-volt battery, although not every Tesla uses the same low-voltage system.
A low-voltage warning, blank screen or no-start condition does not automatically mean the traction battery needs replacement. The smaller battery is not covered by the same long Battery and Drive Unit Limited Warranty.
Ask Tesla to identify the affected system before comparing repair costs.
What Does Tesla’s 70% Battery Capacity Guarantee Mean?
Where the warranty specifies a 70% minimum, it guarantees a capacity floor during the applicable time and mileage period. It does not promise that the battery will retain its original capacity indefinitely.
As a simplified example, a battery that originally had 75 kWh of usable capacity would have a 70% reference point of 52.5 kWh. This illustrates the percentage; it is not a substitute for Tesla’s measurement method or the original-capacity figure Tesla uses for your vehicle.
Less Driving Range Does Not Necessarily Mean Less Battery Capacity
Real-world range also depends on:
- Outside temperature and battery temperature.
- Highway speed, hills and headwinds.
- Cabin heating and air-conditioning use.
- Wheel and tire choices, tire pressure and vehicle load.
- Driving conditions and the vehicle’s range estimates.
A cold-weather trip that uses more electricity does not, by itself, establish permanent capacity loss. Similarly, dividing today’s dashboard range by the original advertised range does not produce a reliable warranty test.
Important distinction: A battery at 80% capacity may disappoint its owner while remaining above the capacity guarantee. A battery at 90% capacity could still have a separate covered defect.
What Can Lead to a Tesla Battery Warranty Denial?
Coverage depends on the cause of the problem and the terms supplied with the vehicle. Situations requiring particular attention include:
- Expired coverage: The applicable date or mileage limit has been reached.
- Normal degradation: Capacity remains above the applicable minimum and no covered defect is found.
- External damage: Collision, underbody impact or flooding damaged the battery.
- Improper work: Damage resulted from an unsuitable repair, modification or charging accessory.
- Ignored instructions or warnings: A resulting failure is linked to disregarded battery-care instructions or active vehicle alerts.
- Vehicle history: Salvage, flood, rebuilt or total-loss history can create serious coverage restrictions.
A claim denial and a completely voided vehicle warranty are different issues. Ask Tesla whether it is rejecting one repair, applying a component-specific exclusion or determining that broader coverage no longer applies.
Does an Independent Repair Automatically Void Everything?
Do not assume that routine outside maintenance cancels every warranty. But opening or servicing the High Voltage battery is different from replacing tires or a cabin filter. Check the battery-specific restrictions before authorizing pack work elsewhere.
If Tesla denies coverage, ask it to identify the relevant exclusion and explain how the facts of your repair fit that exclusion.
What About a Battery Fire?
Tesla’s current Model S, 3, X and Y warranty contains a specific battery-fire provision, including circumstances involving driver error. It also sets exceptions for pre-existing damage and vehicles already totaled. Do not treat every fire as excluded—or promise that every fire is covered. Read the applicable vehicle document.
Review the current North American New Vehicle Limited Warranty, particularly the Battery and Drive Unit and Exclusions sections. Your original document controls if different.
How to Request a Tesla Battery Warranty Evaluation
- Save the alert. Photograph the full warning and any alert code.
- Record the circumstances. Note the date, odometer, charge level, temperature and what the vehicle would not do.
- Check remaining coverage. Save the warranty information shown in your app.
- Submit a service request promptly. Describe the symptom, such as charging stopping repeatedly or an unexpected power limitation.
- Clarify possible charges. Before approving work, ask what diagnosis or repair could become your responsibility if coverage is declined.
- Keep the paperwork. Save estimates, messages, test findings and the final invoice.
Report a developing problem while coverage remains active. Do not assume that noticing a symptom privately before expiration is equivalent to notifying Tesla.
Follow the vehicle’s warning instructions. If the display tells you to stop driving, stop safely and request assistance. Repeated driving or charging attempts are not an appropriate way to test a serious battery alert.
What if Tesla Says the Battery Is “Within Specification”?
Ask what that means in your case:
- Was battery capacity evaluated, or were only fault codes reviewed?
- Did the diagnosis explain the charging or driving symptom you reported?
- Is the problem in the battery, charging equipment or another vehicle component?
- What finding supports the coverage decision?
- What symptoms should trigger another appointment?
If the explanation does not address the problem, request further review through the service conversation. Keep the discussion focused on documented symptoms and diagnostic findings.
Will You Get a New Battery—and a New Eight-Year Warranty?
Neither is automatic. Tesla may use a new, reconditioned or remanufactured replacement. Its battery warranty describes capacity requirements for replacements, rather than promising that every replacement restores the car to factory-new condition.
A battery replaced under the original vehicle warranty generally remains covered only through the original applicable warranty period, subject to law. The replacement does not automatically restart eight years of protection.
What if You Pay for the Replacement Yourself?
A customer-paid qualifying High Voltage battery purchased directly from Tesla is a different situation. Tesla’s current Parts, Body & Paint Repair Limited Warranty lists four years or 50,000 miles, whichever comes first, for vehicle High Voltage batteries, with a separate Roadster exception.
This parts warranty addresses covered failures and does not automatically reproduce the original vehicle warranty’s capacity guarantee. Ask for the specific terms on your estimate and invoice.

| Situation | What to Confirm |
|---|---|
| Tesla replaces a battery under the original vehicle warranty | The remaining original coverage; do not assume a fresh eight-year term |
| You buy a qualifying replacement battery directly from Tesla | The applicable parts warranty, purchase date, mileage limit and covered failures |
| An independent specialist repairs or replaces the battery | That business’s written warranty, labor coverage, exclusions and claim procedure |
Does the Battery Warranty Transfer When You Buy a Used Tesla?
The remaining original warranty can follow the vehicle through a qualifying ownership transfer. You receive the unused portion—not a fresh eight-year battery warranty.
Before buying, ask for:
- The original warranty documents and coverage start date.
- Current mileage and remaining battery coverage.
- Battery replacement or repair invoices.
- Information about persistent battery or charging alerts.
- Collision, flood, title and total-loss history.
“Battery replaced recently” needs further explanation. Was it a warranty replacement, a customer-paid Tesla replacement or an independent repair? Those situations can leave the buyer with very different protection.
What Happens After Eight Years?
The battery does not expire when the warranty does. If it still works properly and provides enough range, reaching eight years is not itself a reason to replace it.
After coverage ends, the financial risk shifts toward the owner. If a problem develops, request an itemized diagnosis before deciding whether to repair the car, replace the pack or sell it.
Ask These Questions Before Approving a Major Repair
- Has the battery pack itself failed, or is another component responsible?
- Does the estimate include diagnosis, labor, taxes and related parts?
- Is the proposed pack new or remanufactured?
- What written warranty comes with the work?
- Are suitable repair alternatives available?
- How does the total compare with the car’s value and overall condition?
There is no single replacement price that fits every Tesla. Model, pack version, repair scope and service options change the bill. See our guides to EV battery replacement costs and Tesla battery repair alternatives.
Can You Extend Tesla Battery Coverage?
Tesla offers a separate High Voltage Battery and Drive Unit Extended Service Agreement for eligible Model 3 and Model Y vehicles. Published coverage is up to 24 months or 30,000 miles after the original battery warranty expires, with a $500 deductible per covered service visit.
Eligibility is restricted. Tesla currently requires an eligible vehicle purchased directly from Tesla with active original battery coverage; leased, branded-title and total-loss vehicles are excluded. There is no purchase grace period after the original battery warranty expires.
Check the app under Upgrades > Service Plans and read the Battery ESA eligibility and terms. Do not assume an ordinary extended service plan includes the traction battery.
Battery Warranty Mistakes That Can Cost You
- Waiting for the battery to reach 70% despite a fault. A covered defect can qualify separately from capacity loss.
- Confusing battery types. A low-voltage battery problem is not automatically a traction-battery failure.
- Ignoring mileage. Coverage can finish well before the eight-year anniversary.
- Expecting an automatic new pack. Repair or a remanufactured replacement may be the approved remedy.
- Assuming replacement restarts the clock. Confirm the remaining coverage in writing.
- Approving outside pack work before checking coverage. Understand the battery-specific restrictions first.
Frequently Asked Questions
Will Tesla replace my battery for free?
It may repair or replace it when a covered defect or qualifying capacity loss occurs within the applicable warranty period. Age alone, reduced dashboard range or an owner’s request does not establish eligibility.
What happens after eight years of a Tesla battery?
The original battery warranty may end, unless mileage ended it earlier. A functioning battery can remain in service; warranty expiration is not a replacement schedule.
At what mileage do you replace a Tesla battery?
There is no universal mileage. Replacement depends on condition, faults, usable capacity and whether repair makes sense. A warranty mileage cap is a coverage limit, not a prediction of failure.
Does charging to 100% void the warranty?
A single 100% charge does not, by itself, establish that the whole warranty is void. Follow the charging guidance for your exact vehicle and battery. Damage attributed to disregarding applicable instructions may be excluded.
Is an LFP battery covered differently?
Check the vehicle’s actual warranty. Battery chemistry alone does not tell you its mileage limit, and charging recommendations can differ between battery configurations.
How common is Tesla battery failure?
This warranty guide does not establish a verified failure rate. Battery degradation, low-voltage battery replacement and complete traction-battery failure are different events and should not be combined into one statistic.
Can a Tesla last 500,000 miles?
An individual high-mileage example does not guarantee that another Tesla will reach 500,000 miles—or do so on its original battery. Check repair history when evaluating such claims.
What wears out fastest on a Tesla?
That varies with the model and use. Tires, filters and other maintenance items should not be confused with battery-pack failure. The battery warranty does not cover every ownership expense.
Does the battery warranty guarantee a rental or loaner?
Do not assume transportation is automatically included. Ask Tesla what assistance is available for your appointment and confirm any charges before arranging it. See our guide to loaners during warranty repairs.
