Electric vehicle (EV) battery warranties
Electric vehicle (EV) battery warranties generally cover defects and capacity loss but include specific exclusions and limitations.
Standard Warranty Coverage
- Typically, EV battery warranties last 8 years or 100,000 miles as mandated by federal law in the U.S., with some states like California requiring longer coverage (up to 10 years or 150,000 miles).
- The warranty usually covers battery capacity dropping below a certain threshold, commonly 60-70% of the original capacity, rather than total failure alone.
- Some manufacturers offer longer warranty periods or higher mileage limits, such as 10 years or warranties extending beyond 150,000 miles.
Common Exclusions and Limitations
- Physical damage: Any battery damage from accidents or external impacts is excluded from warranty coverage because warranties only cover defects or failures originating from manufacturing, not damage caused by outside influences.
- Improper use or maintenance: Use of non-standard charging equipment, failure to install required software/firmware updates, or neglecting recommended maintenance routines can void the warranty.
- Environmental and extreme conditions: Exposure to extreme temperatures or conditions that cause battery damage may lead to denied claims.
- Warranty start and end: Warranty coverage begins at the sale date/mileage of the vehicle and ends either when the time or mileage limit is reached.
Summary
EV battery warranties provide a baseline of 8 years or 100,000 miles coverage against manufacturing defects and excessive capacity loss (usually below 60-70%), but exclude physical damage, improper usage, neglect, and environmental abuse. Always review the specific warranty terms and fine print from the manufacturer for precise details.
