Chevy Volt's Batteries Protected by 8-Year / 100,000 Mile Warranty

General Motors is trying to ease buyers concerns about battery life by announcing it will guarantee the upcoming Chevrolet Volt's lithium-ion battery pack for 100,000 miles or a period of eight-years, whichever comes first.

In addition, GM noted that the warranty will be transferable at no cost to a new owner should a Volt buyer decide to sell his car. According to the Detroit automaker, "it's the automotive industry's longest, most comprehensive battery warranty for an electric vehicle".

The Volt's battery warranty covers all 161 battery components - and that's a pretty good thing for buyers as the cost of the 400 pound battery has been estimated between $8,000 to $10,000.

The car, which uses a small gasoline engine to produce electricity once the battery is depleted, will be priced at around $40,000 (before federal incentives) when it hits U.S. showrooms this fall.
