What You Need to Know About Electric Car Battery Warranties!

Warranties are available for electric car batteries; however, the details of these warranties might differ based on the manufacturer, the model, and occasionally even the location. We examine the fundamentals of electric car battery warranties, their scope, and consumer information to be aware of when evaluating an electric vehicle (EV) warranty conditions below.

General Principles of Electric Car Battery Warranties

Standard Warranty Periods: For their electric car batteries, the major EV manufacturers offer warranties that last 8 to 10 years or between 100,000 and 150,000 miles, whichever comes first. One of the costly parts of an electric car is the battery, and these warranties reassure consumers about its lifespan and dependability.

Coverage of Battery Degradation: Batteries with significant capacity loss under warranties. Because the battery’s ability to hold a charge diminishes with time if the capacity drops below a predetermined threshold (about 70–80% of its original capacity) during the warranty period, most manufacturers guarantee to replace or repair the battery. 

Manufacturer-Specific Battery Warranties


Depending on the model, Tesla offers an 8-year battery and drive unit warranty with mileage restrictions.


A 100,000-mile or eight-year battery guarantee with the Nissan Leaf. During the warranty, Nissan promises a minimum of 9 out of 12 bars, or around 70%, of battery capacity.  


The battery in the Chevrolet Bolt EV is guaranteed to retain at least 60% of its initial capacity for eight years, or 100,000 miles, whichever comes first.


The battery warranty on BMW electric cars, including the i3 and i4, is eight years or 100,000 miles. According to the warranty, the battery will always hold at least 70% of its initial capacity.

Hyundai and Kia:

Kia and Hyundai provide some of the best warranties. Like the Hyundai Kona Electric and Kia e-Niro, their electric vehicles (EVs) come with an 8-year or 100,000-mile warranty that covers any loss of battery capacity below 70%.

Important Considerations for Consumers

Understand the Terms: It is imperative that buyers carefully read and comprehend the terms of the warranty. It helps to know what is and is not covered so that proper care is to maintain the warranty and avoid unforeseen costs.

Maintain Proper Documentation: It is essential to keep thorough records of all repairs and maintenance done on the car. This documentation may be necessary if a warranty claim is necessary.  

Follow Manufacturer Recommendations: It is possible to contribute to the longevity and preserve warranty coverage by following the manufacturer’s recommended maintenance schedule and charging procedures.

Be aware of the Fine Print: Certain warranties have restrictions or requirements. For instance, for the guarantee to be effective, there may be a necessity for yearly battery checkups or other requirements.


Electric car battery guarantees provide a great deal of comfort to customers by guaranteeing the dependability and durability of the most vital part of their electric vehicle. Several manufacturers offer a comprehensive warranty for 8 to 10 years, encompassing problems and considerable capacity reduction. Customers should be careful to study the conditions, keep accurate records, and follow manufacturer recommendations to ensure they get the most out of the battery warranty on their electric vehicle. This kind of attention to detail can improve an electric vehicle’s overall ownership experience and help offset the high expenses of battery replacement or repairs.
