How Much Does It Cost to Replace a Tesla Battery?
Last Updated on February 5, 2026
A Tesla has more than one “battery.” There’s a large high-voltage battery pack that powers the motors, and there’s also a smaller low-voltage battery that runs electronics. Replacing the low-voltage battery can be similar to replacing an ordinary car battery—but replacing the high-voltage pack is a completely different (and much more expensive) repair.
So, what does it really cost to replace a Tesla’s high-voltage battery pack? It depends on your model, battery size, whether the replacement is new vs. remanufactured, and whether you’re still within Tesla’s warranty window.
- High-Voltage Battery Work Is a Big Repair: A Tesla pack replacement is typically a five-figure job when you’re out of warranty.
- Warranty Coverage Is the Game-Changer: Tesla’s battery warranty is 8 years with mileage limits by trim and includes a 70% capacity retention guarantee.
- Insurance Can Help in the Right Scenario: Collision or comprehensive may cover battery damage from a covered loss, but not normal aging or degradation.
- Diagnose Before You Replace: Battery warnings don’t always mean a full pack swap—get diagnostics and a written estimate before making decisions.

Tesla Battery Replacement Cost Range
In most out-of-warranty cases, a full high-voltage battery replacement is a five-figure repair. Publicly reported pricing and invoices commonly land in the $15,000 to $22,000 range for a complete pack replacement, with meaningful variation by model and pack size.
To make the numbers easier to compare, here are examples from publicly shared data and invoices (not a quote for your vehicle):
| Scenario | What’s Included | What You Might See | Source |
|---|---|---|---|
| Model 3 pack replacement example | Parts + labor for a full high-voltage pack swap | $15,799.27 (example invoice) | Recurrent (invoice example) |
| Out-of-warranty replacement (general range) | Complete pack replacement | $15,000–$22,000 (reported range) | Recurrent (reported range) |
Important: Pricing changes over time, and your final total can swing based on labor rates, local taxes/fees, parts availability, and whether Tesla installs a new or remanufactured pack.
What Drives the Cost of a Tesla Battery Replacement?
Tesla high-voltage battery replacement cost is mostly driven by the pack itself—but there are several other factors that can move the number up or down.
| Cost Driver | Why It Matters |
|---|---|
| Model and Battery Size | Bigger packs generally cost more to replace. |
| New vs. Remanufactured Pack | Many replacements use remanufactured packs; pricing can differ from a brand-new unit. |
| Labor and Diagnostics | High-voltage work requires specialized training, safety procedures, and equipment. |
| Related Parts and Fluids | Some jobs include additional components (connectors, seals, skid plates, coolant, fasteners). |
| Location and Taxes | Regional labor rates and taxes/fees can materially change the out-the-door total. |
Quick tip: If your Tesla shows a battery-related warning, use the app to request service and ask for a written estimate. “Battery issue” can sometimes mean a sensor, coolant component, or low-voltage problem—not automatically a full pack replacement.
How Tesla Battery Replacement Typically Works
Tesla’s high-voltage battery is a sealed pack made up of many cells and modules. In many repair situations, Tesla service will replace the entire pack rather than attempting a module-level rebuild on the vehicle. The removed pack is commonly returned through Tesla’s channels for remanufacturing or analysis, and the replacement pack may be new or remanufactured depending on availability and the repair context.
This “pack swap” approach can be faster and more consistent than attempting an on-car rebuild—but it’s one reason the repair can be so expensive when you’re out of warranty.
Other Options for Replacing a Tesla Battery
Some owners explore third-party options—especially if they’re out of warranty and facing a large estimate. Depending on the issue, a qualified EV repair facility may be able to repair the pack, source a used pack, or replace specific components at a lower cost than a full OEM pack swap.
Local EV Repair Shops: Look for a shop that explicitly advertises high-voltage EV training and Tesla experience. Battery diagnostics and isolation testing require specialized tools and strict safety procedures.
DIY Repairs: High-voltage systems are dangerous. DIY battery work is not recommended for most drivers due to electrocution risk, fire risk, and the likelihood of expensive mistakes.
Does Insurance Cover Tesla Battery Replacement Costs?
Auto insurance generally doesn’t pay to replace a battery because it’s “old,” degraded, or failing from normal use. Like any other vehicle, insurance doesn’t cover routine maintenance or wear-and-tear.
However, insurance can help in the right scenario: if the battery is damaged in a covered loss (like a collision, fire, vandalism, or certain types of road debris damage), then collision or comprehensive coverage may pay to repair or replace the damaged battery pack—subject to your deductible and policy limits. This is true whether you have Tesla Insurance or coverage from another carrier.
If your Tesla can’t drive after a covered claim, you may also be able to use roadside assistance coverage (if you carry it) for certain services. Some drivers also use third-party roadside programs like AAA for towing and related help.
Depending on your situation, your policy (or membership) may help with towing or certain service calls (like jumpstarts for low-voltage issues), but benefits vary by plan and provider.
Does My Tesla Warranty Cover Battery Replacement?
Battery replacement is most manageable when you’re still under warranty. Tesla’s battery warranty is separate from the basic vehicle warranty and includes a capacity retention guarantee.
As a general rule, Tesla’s Battery and Drive Unit Limited Warranty provides 8 years of coverage and includes a minimum 70% battery capacity retention guarantee during the warranty period (mileage limits vary by model and trim). For details, see Tesla’s warranty resources and your vehicle’s documents. (Related: what a car warranty covers.)
| Model/Trim (Common Examples) | Battery Warranty Term | Capacity Guarantee | Reference |
|---|---|---|---|
| Model 3 / Model Y Rear-Wheel Drive (select trims) | 8 years or 100,000 miles | Minimum 70% retention | Tesla Vehicle Warranty |
| Model 3 / Model Y Long Range & Performance (select trims) | 8 years or 120,000 miles | Minimum 70% retention | Tesla Vehicle Warranty |
| Model S / Model X (select trims) | 8 years or 150,000 miles | Minimum 70% retention | Tesla Vehicle Warranty |
Note: Warranty eligibility depends on the cause of the problem, vehicle history, and exclusions in Tesla’s warranty documents. Always confirm coverage inside your Tesla app (“Specs & Warranty”) or with Tesla Service.
Signs Your Tesla Battery May Need Service
Most drivers will notice gradual range loss over time, which is normal for EVs. What typically triggers service is a warning message, charging trouble, or a sudden performance change.
- Battery or powertrain alerts in the vehicle or Tesla app
- Sudden, unexplained range reduction (not tied to cold weather, speed, or tire pressure)
- Charging issues (won’t charge, repeatedly stops charging, or charges abnormally slowly)
- Vehicle won’t drive or enters reduced-power mode
- Unusual cooling behavior (fans running excessively) or visible fluid leaks
Final Word: Tesla Battery Replacement Cost
A Tesla high-voltage battery replacement can be expensive out of warranty—often in the $15,000 to $22,000 range for a full pack replacement, depending on model and circumstances. The good news is that battery replacements appear to be relatively uncommon for modern EVs, and Tesla’s battery warranty provides long-term protection with a 70% capacity retention guarantee during the warranty period.
If you’re seeing warnings, range issues, or charging problems, start with Tesla diagnostics and request a written estimate. If you’re out of warranty, compare options carefully—especially the warranty and safety standards of any third-party battery work.
