Hybrid Battery Service – Warranty Policy
At Hybrid Battery Service, we guarantee reliable and safe operation of our hybrid batteries throughout the stated warranty period.
We stand behind the quality of our batteries. Each battery includes a minimum guaranteed lifespan that remains shorter than its potential service life.
1. Warranty Periods by Battery Capacity
Our warranty depends on the Battery Cell Capacity (Ah), which helps reflect the durability of each battery type.
What Is the Difference Between Our Warranty Options?
When you select a warranty option from Hybrid Battery Service, you choose a battery configuration with a corresponding tested capacity. You are not simply purchasing longer coverage for the same battery.
For longer-warranty options, we select battery modules that meet higher usable-capacity requirements. The table below shows the approximate capacity for each warranty option. Vehicle model availability may vary.
Warranty duration describes the coverage period under this policy. However, it does not represent the exact service life of the battery.
| Warranty Period | Battery Cell Capacity | Comments |
|---|---|---|
| 6 months | ~3.7 – 4 Ah | Minimum protection for smaller-capacity batteries |
| 1 year | ~4 Ah | Basic-capacity batteries |
| 2 years | ~4.6 Ah | Mid-range capacity batteries with guaranteed safe operation |
| 3 years | ~5.2 Ah | Premium mid-to-high capacity batteries (~80% of new) |
| 4 years | ~5.8 Ah | High-capacity batteries with a minimum guaranteed lifespan (~89% of new) |
| 6 years | ~6 Ah | Select models only. See details below. |
*We offer the 6-year warranty option only for Toyota Prius Gen 2 (2004–2009), Toyota Prius Gen 3 (2010–2015), Toyota Prius V (2012–2017), and Lexus CT200h. You must select the 6-year warranty option at purchase to receive this coverage. All other models offer warranty options of up to 4 years.
Note: New batteries with 6.5 Ah capacity typically last 8–15 years. Therefore, our warranty remains conservative and realistic.
2. Transfer of Warranty
- You may transfer the warranty to a new owner within 30 days of the vehicle sale.
- We allow one transfer per battery. To complete the transfer, submit a copy of the sales receipt and the new owner’s name to Hybrid Battery Service.
3. What the Warranty Covers
When Hybrid Battery Service confirms a warranty-covered battery defect, we will repair or replace the battery at no charge for the covered repair or replacement.
- Hybrid Battery Service technicians provide technical support and consultation free of charge.
- For approved warranty service at Hybrid Battery Service, HBS includes the required diagnostic, battery removal, and reinstallation labor.

6. Why Choose Hybrid Battery Service Warranty
- Over more than a decade of work, our average defect rate has never exceeded 2%.
- Conservative approach: We set the guaranteed period shorter than the actual expected lifespan.
- Transparent and simple process: We offer warranty periods from 6 months to 6 years based on the selected battery configuration and battery cell capacity (Ah). Higher-capacity batteries provide more usable electrical energy and qualify for longer warranty coverage.
- Certified technician support: Our team provides fast, professional assistance whenever you need it.
