Hybrid Battery Service – Comprehensive Warranty for All Hybrid Batteries

Hybrid Battery Service – Warranty Policy

At Hybrid Battery Service, we guarantee all our hybrid batteries for reliable and safe operation throughout the stated warranty period.
We are confident in the quality of our batteries: each battery comes with a minimum guaranteed lifespan that is always shorter than the actual potential lifespan of a battery.

1. Warranty Periods by Battery Capacity

Our warranty depends on the Battery Cell Capacity (Ah) to reflect the true durability of each battery type:

*The 6-year warranty option is available only for Toyota Prius Gen 2 (2004–2009), Toyota Prius Gen 3 (2010–2015), Toyota Prius V (2012–2017), and Lexus CT200h. Coverage applies when the 6-year warranty option is selected at purchase. All other models offer warranty options up to 4 years.

Note: New batteries with 6.5 Ah capacity last 8–15 years, so our warranty is always conservative and realistic.

2. Transfer of Warranty

• Warranty can be transferred to a new owner within 30 days of vehicle sale.
• One transfer per battery is allowed, with a copy of the sales receipt and the new owner’s name submitted to Hybrid Battery Service.

3. What the Warranty Covers

If Hybrid Battery Service confirms that a battery has a defect covered by the warranty, we will repair or replace the battery at no charge for the covered battery repair or replacement.

• Technical support and consultation from Hybrid Battery Service technicians are provided free of charge.
• When an approved warranty repair or replacement is performed at Hybrid Battery Service, HBS diagnostic, battery removal, and reinstallation labor required for that warranty service is included.
• When an approved warranty repair or replacement is performed through HBS Mobile Service, HBS technician labor is included. Travel, mileage, and logistics charges may apply and will be confirmed before the service is scheduled.
• Diagnostic, removal, installation, towing, or other labor performed by an independent repair shop, dealership, or third-party mechanic is not covered unless Hybrid Battery Service specifically approves the expense in writing before the work is performed.

Warranty Shipping and Transportation

Customers must contact Hybrid Battery Service before shipping a battery for a warranty claim. We will provide the appropriate return and shipping instructions.

If our inspection confirms that the battery failure is covered by the warranty, Hybrid Battery Service will cover the required shipping of the battery to and from our facility as part of the approved warranty claim.

If inspection determines that the reported problem is not caused by a covered hybrid battery defect, the customer is responsible for the applicable shipping and transportation costs. If the customer requests a replacement battery even though no covered battery defect is confirmed, the customer is also responsible for the applicable shipping costs.

Additional return and transportation terms are described in our Return Policy.

4. Exclusions

• Improper installation.
• Damage during shipping not documented at delivery.
• Commercial vehicle use (taxi, delivery, rideshare) unless declared at purchase.
• Damage from vehicle misuse or lack of maintenance.
• Vehicle modifications not compliant with manufacturer specifications.
• Removal, tampering, or damage to warranty labels.
• Third-party diagnostic, removal, or installation charges that were not approved by Hybrid Battery Service in writing before the work was performed.

5. How to File a Warranty Claim

1. Notify Hybrid Battery Service within 5 days of discovering a suspected battery problem.
2. Provide the diagnostic trouble codes (DTCs) from the vehicle, the vehicle VIN, the date of the diagnostic scan, and any other information requested by our technicians.
3. Our technicians will review the diagnostic information and provide the next steps. Do not ship the battery until Hybrid Battery Service provides return instructions.
4. If requested, the battery must be returned to Hybrid Battery Service for inspection and testing. The inspection determines whether the reported failure is covered by the warranty.
5. If a covered hybrid battery defect is confirmed, Hybrid Battery Service will repair or replace the battery and cover the required warranty shipping in accordance with this Warranty Policy and our Return Policy.
6. If inspection determines that the reported problem is not caused by a covered hybrid battery defect, the warranty does not cover the related shipping or optional replacement costs. The customer may request a replacement battery, but applicable shipping costs will be the customer’s responsibility.
7. Do not authorize third-party diagnostic, removal, installation, towing, or other warranty-related work before contacting Hybrid Battery Service. Third-party expenses are covered only when specifically approved by Hybrid Battery Service in writing before the work is performed.

6. Why Choose Hybrid Battery Service Warranty

• Over more than a decade of work, our average defect rate has never exceeded 2%.
• Conservative approach: The guaranteed period is always shorter than the actual expected lifespan.
• Transparent and simple process: 6 months – 6 years warranty depending on the selected battery configuration and battery cell capacity (Ah). Higher-capacity batteries provide more usable electrical energy and are paired with longer warranty coverage.
• Certified technician support: Fast, professional assistance whenever needed.

7. Legal Disclaimer

By accepting the battery, you agree that Hybrid Battery Service is not responsible for any indirect damages, loss of your property, or time, except for cases covered under this warranty.
