WHAT IS THE EXPECTED EV BATTERY LIFESPAN?

Understanding propulsion EV battery life is key to feeling confident about making the switch to an electric vehicle like the GMC HUMMER EV Pickup, GMC HUMMER EV SUV or GMC Sierra EV. Learn what you can expect from a GMC propulsion EV battery lifespan, what’s covered under the limited warranty and how proper care can help you get the most out of your electric vehicle for years to come.

What is the life expectancy of an EV battery? The propulsion battery packs found in HUMMER EVs* and Sierra EVs,* as well as their internal components, are covered by a limited warranty* for 8 years or 100,000 miles, whichever comes first. Like all batteries, the amount of energy that the high voltage propulsion battery can store will decrease with time and miles driven. The limited warranty covers issues where the battery capacity falls below 75% of its original value during the warranty period, as determined by a certified dealer, with a battery appropriate for the age and mileage of the vehicle. If a repair or replacement is needed, it will be handled by a GMC EV Certified Dealer using new or refurbished components appropriate for your electric vehicle’s age and mileage.
