The Chevy Volt is finally coming together. GM just went public with the details surrounding its battery warranty and it’s on the same level as the Prius’s. The auto maker will cover the Volt’s LG Chem lithium-manganese pack for eight years or 100,000 miles. This comes after extensive testing over a three-year period in which testers logged over 1 million miles of driving and 4 million hours on the battery packs. Needless to say that GM tested the entire system thoroughly.
