Chevrolet is backing its battery technology with what it hopes will be a confidence-inspiring guarantee for prospective Volt buyers.

The GM brand has announced it will offer an 8-year, 100,000 mile (160,000 km) warranty on the battery for the Chevy Volt model when it debuts next year. It is one of the most comprehensive warranty offered by any automaker on batteries, covering all 161 parts of the Volt power-pack. The warrant is also transferable to new owners of the vehicle without charge.

"The Chevrolet Volt's batteries have exceeded our performance targets and are ready to hit the road," said GM's director of global electrical systems, Micky Bly, in a press release.

The Chevy Volt is an extended-range, all-electric vehicle powered by an electric motor producing 112 kW (150 bhp) and 273 lb-ft (370 Nm). The Volt can run up to 40 miles (65 km) on electrical current alone. Afterwards, a small gasoline engine kicks in to serve as a generator to charge the 16-kWh lithium-ion battery and extend the range to about 340 miles (547 km). Chevrolet says the Volt will get 230 mpg - less than 1 liter per km, but that figure is still pending certification.

The Chevrolet Volt is set to go into production later this year. The Volt will go on sale in the U.S. and Europe in 2011.
