Later today, General Motors will make some announcements* regarding the battery pack in the Chevrolet Volt. Volt marketing director Tony DiSalle and vehicle line director Tony Posawatz will be hitting the keyboards this afternoon to answer any questions from readers about the news. General Motors' massive battery lab in Warren, MI has been cycling battery packs for more than two years through accelerated tests in order to have confidence that the packs will last for 10 years and 150,000 miles. All indications so far are that GM's very careful handling of the battery charging and preconditioning will achieve the desired results.

The Brownstown, MI battery factory has been building packs on production tooling since January of this year for installation into the production verification vehicles being built at the Detroit-Hamtramck assembly plant. The facility will now ramp up for full production of the Volt starting this fall. The webchat starts at 4 p.m. EDT today and you can submit your questions using the form after the jump.

*UPDATE: Here's the news: General Motors announces 8-year/100,000-mile warranty for Volt battery

      If the warranty is going to be 10 years, 150k miles. The test battery better last way beyond that.

      For reference, Toyota tested Prius battery pack to 180 miles and saw very little degradation.

      With the info coming out of GM regarding how the Gen2 Volts may have a slightly smaller pack with a lighter pack conditioning system, it may be that the 2011 and 2012 Volts will be collectors items that are overbuilt in a very good way. But I am still waiting for confirmation that Posawitz statement that the charge sustaining mpg is still at 50 mpg, as he stated 5 or 6 months ago. After that, the only question is, will the MSRP be below $37,500. If it is, GM will have a moster hit on their hands.

      a surprise of 100 mile electric only range? dreaming of course... that would take a bite out of Nissan's lead though...

        The ability to drive over 75 miles in a day is a pretty big bite in itself... Unless of course you fancy effectively issuing yourself a house arrest. :P

        see, I was only dreaming...

        I drive over 100 miles in a day sometimes, but usually about 60-75... I'd like to be able to use all electric during the week for work (150 mile range or better is perfect) but have the range extender for long trips (which would be impossible in the Leaf)

        If I had a Volt, I would have to use gas, and while not as much, it's not worth it to give up my 40mpg Fit just yet... 4 years and I am hoping there is a more real world friendly fully electric car

      They're going to have a very nice warranty for their batteries, longer than their typical 5 years/100,000 miles.

      Typo ^ 180k miles
