Which EV Brand Has the Best Battery Warranty?

Battery warranties are one of the most important factors to consider when buying an electric vehicle (EV). Since EV batteries degrade over time, a strong warranty ensures peace of mind and protects against expensive repairs or replacements. So, which EV brand offers the best battery warranty? Let’s take a deep dive into the top automakers, comparing their warranty coverage, mileage limits, and capacity guarantees.

What to Look for in an EV Battery Warranty?

• Duration & Mileage – Warranties typically last 8–10 years or 100,000–175,000 miles, whichever comes first.
• Battery Capacity Guarantee – Some automakers promise the battery will retain at least 70% of its original capacity during the warranty period.
• Transferability – If you sell your EV, some warranties transfer to the new owner, increasing the car’s resale value.
• Exclusions & Conditions – Some warranties exclude battery damage caused by fast charging, extreme temperatures, or software updates.
