Eight years or 100,000 miles is common in the US. Some makers offer 10 years or 150,000 miles.
| Maker | Typical battery warranty | Capacity threshold |
|---|---|---|
| Hyundai and Kia | 10 yr / 100,000 mi (original owner) | 70% |

| Ford | 8 yr / 100,000 mi | 70% |

Figures are typical ranges and vary by car, climate and driving style.
What is covered
Usually a drop below a set capacity, often 70 percent, or a defect that prevents the car from working. Normal gradual loss is not a fault.
A warranty is a promise with fine print.
Fine print
Warranty can be reduced for second owners or for misuse. Check how fast charging and storage are treated.
Worth doing
- Read the warranty book
- Ask about second-owner terms
- Keep service records
- Note any exclusions
Practical tip
Warranty terms differ by region and model year. Confirm them with the manufacturer before you buy.
Bottom line
Read the capacity threshold and the transfer rules before you rely on it.
Specifications, prices and rules change. Confirm current details with the manufacturer or the relevant authority before you buy or repair.
