Battery Replacement: What You Need to Know - ALL TEsla models

Replacing a battery in a Tesla—or any EV—can be a significant expense. A brand-new Tesla battery can cost over $10,000 USD, making it one of the most costly components to replace. The more affordable alternative is to purchase a used battery, which typically costs around $6,000, depending on availability and condition.

However, used batteries often come without a warranty or only limited coverage for a short period. Since the battery is essentially the heart of the vehicle, this isn’t a decision to take lightly. In an electric car, the battery powers everything—without it, the vehicle simply won’t function. That’s why it’s critical that any replacement battery be in reliable, tested condition. You’re not just swapping out a part—you’re restoring the core system that makes the vehicle run.

In some cases, the existing battery may be repairable, especially if the issue stems from a few bad cells or a balancing problem. To determine that, we’ll need to perform a full diagnostic scan on the vehicle. This will allow us to assess the battery’s health and give you a clear, informed recommendation on whether a repair or full replacement is the best option.
