GM says Volt battery system will have 8-year, 100,000-mile warranty
Automotive News -- July 14, 2010 - 12:01 am ET

General Motors Co., preparing to launch the first U.S. mass-market plug-in
hybrid, will offer buyers of its Chevrolet Volt an eight-year, 100,000-mile
warranty on the lithium-ion battery's 161 components.
The warranty also includes the battery's thermal management system, charging
system and electric-drive components, GM said today.
The Volt, which goes on sale in October or November, can run for up to 40
miles on battery power before it switches to power from a gasoline-powered
engine. A battery can charge in 8 to 10 hours on 120-volt power or about
four hours through a 240-volt hookup.
GM intends for the warranty length to give customers confidence in the
Volt's unfamiliar plug-in technology, said Micky Bly, GM's executive
director of global electrical systems, today at GM's battery plant in
Brownstown Township, Mich.
"It's one less question for the dealer," Bly said. GM has not announced the
warranty for the Volt's gasoline-powered engine, but Bly said it would be at
least as long as GM's standard five years or 100,000 miles.
The Volt battery's longevity stems in large part from the liquid heating and
cooling system that keeps the battery at optimal temperatures. The Volt is
the only such mass-market vehicle with a liquid-powered thermal management
system, GM said.
For example, the Nissan Leaf electric vehicle has an air-cooled battery.
Nissan hasn't released warranty information for the Leaf, which goes on sale
The Brownstown plant has been building prototypes for Volts since January
and will soon start batteries that will go on vehicles destined for

I think it is commendable that GM is going to provide such a long warranty
period for the batteries and related electronics in the Volt.....BUT,
suppose they get it wrong (and when hasn't GM gotten new technology wrong?).
I suppose they have to do something to offset the high cost of the Volt, but
if I was a GM stockholder, I would be worried that GM is openning themselves
up to huge warranty liability down the road.

Exactly like Mazda and there confidence in the Wankel rotary engine
which just about bankrupted them, until Ford bought them out.

Say for instance you have a lead acid battery that is in good condition,
but it has discharged and the battery is very cold, around zero degrees
(wintertime) and you want to charge up the battery.At that cold
temperature, it won't charge up, or will it?
