General Motors announced recently that they would be guaranteeing the warranty on the electric car battery in the Chevy Volt for longer than their traditional car warranties. While conventional car engines get a warranty for up to 5 years or 100,000 miles, the Volt's LG Chem lithium-manganese battery is guaranteed for up to 8 years or 100,000 miles, the company announced recently.
The Chevy Volt can drive distances up to 40 miles on its rechargeable battery before a small gas engine takes over. GM announced the extended warranty after the completion of over 3 years of extensive testing of the vehicle and its 16 total kwh battery pack.
According to GM, the key features of the Volt battery that are giving them the confidence to offer such a long warranty are the battery's thermal management, cell design, energy management, and comprehensive diagnostic systems. Besides the battery, GM is also offering these additional warranties on the Volt:
- 100,000 mile/5-year transferable Engine Limited Warranty (for Range Extender)
- 100,000 mile/5-year 24/7 Roadside Assistance Program
- 100,000 mile/5-year 24/7 Courtesy Transportation Program
- 36,000 mile/ 3-year no deductible Bumper-to-Bumper transferable warranty
- 100,000 mile/6-year corrosion protection
