Has any forum member replaced the batteries yet?

In addition to this story, I have not heard of any forum member who had to have a full battery replaced. I believe I have seen a few that needed a small part of the battery replaced. Chevy designed the battery so that it could be repaired or only have certain parts replaced. Additionally, liquid cooling and other tech has made it so the batteries have little to no range degradation over time. Most 2011 owners report no more than a mile or 2 of range loss.
Finally, the entire Voltec system is warrantied for 8 years or 100,000 miles. If you plan to use the car for any amount of time less than that, you should not be concerned.

Someone replaced their battery after a section of it failed. It was done DIY and looks very promising for anyone with some mechanical experience.

Not sure where you would fit nearly double the battery without removing the gasoline engine.
So far we have owned 2 Volts, a 2014 Premier, and a 2016 Volt Premier in which we traded in the 14 Volt for. Here in Oregon the warranty period for the propulsion battery is 150,000 miles. We had over 40,000 miles with the 14 Volt, and now have nearly 47,000 on the 16 Volt. We have noticed no range or battery degradation for either vehicle and we have a level 2 charger, Clipper Creek HCH 40 amp unit....
Think they mean the main car battery.
I was thinking maybe an improved battery in the same size, if possible? Perhaps a solid state battery in the future..

Bolt's (really, pretty much all BEVs) battery is much better packaged, fitting over 3x the capacity in less "intruding into the cabin space". I've always fantasized about a gen3 Volt with half or third of a Bolt's battery pack in it (in floor)... tons of range, no loss of cabin space, 3 real rear seats, etc.
As more energy dense cells come out, you could theoretically replace them inside the current pack's T-shape for a significant range boost. Doubt that will ever be available commercially, though.
Now you have. My early 2018 experienced a gradual high voltage battery failure about 4 months after purchase. GM provided a new battery at no cost. This took almost two weeks to ship and install. I had a loaner Malibu, so that was fine.
Just curious — did they say what caused the systemic failure of the battery pack?

Nope. My local dealer opened a ticket with GM Technical Assistance Center, and sent them diagnostic logs. The TAC made the call that the battery was bad, and I doubt the local dealer understands what happened either.
I had never heard of the TAC before this. Here's a short writeup about them:

A few out of 200,000. Free under the 8 year/100k mile (10 year/150k mile in CA) warranty. Outside the warranty DIY or via a dealer, costs will varywidely.
No, nor do I expect them to ever be available. Used from auto salvage yards are available.
GM's pre-production testing went to 200,000 miles (2X warranty) with no issues. Unlike air-cooled battery's from Nissan and others, GM's are aggressively (Dextron) water cooled to keep them from the degradation caused by heat, a known battery killer.
Here's some anecdotal data: my 2011 Volt is still going strong, no issues.
