Well after calling around, the Gm batteries are on the national control list and no one but local dealers can get them and they are $3220.50 plus labor.
Looks like prices have gone up. It's definitely worth calling around for an "out the door" price.
Given what's in the pack (40 Toyota modules), it's one of the cheapest packs they (Toyota) produce.
If this is a vehicle you want to go another 100,000 miles, then there really isn't an option besides new, unless you're willing to deal with it 2-3 times.
I would just replace the bad cells, it isn't very hard to do, maybe 1.5 hours to remove and diagnose, 1 hour to reinstall, the cells are $38 on amazon & ebay. It is not dangerous, there are two kill switches before you can even open the battery, one is passively connected to the cover. Same cells as Prius just 40 instead of 28. look on youtube for "Prius cell test" or "replacement" I will warn you the battery is extremely heavy, probably 200+ pounds of dead weight, I did it by myself but it is a two man job....oh and take it out the tailgate, much easier than struggling through the door.

Doesn't sound like it worked out for you though... why would you recommend it?
A lot of my battery replacement decision on my 2009 Tahoe with 197,000 miles would be based upon actual vehicle value. There is a reason that Auto Insurance companies total out older vehicles that cost over 1/2 the value to repair. IT DOES NOT MAKE ECONOMIC SENSE. Now a few years back a medium to high mileage 2008 or 2009 or 2010 Tahoe/Yukon or Escalade might have had some real value. But at almost 10 years old and most approaching 200,000 miles the silly things are in the 6 to 7k value range. I personally would not consider a NEW battery at + $3,500.00 to be a savvy economic move at this point. If I need too I will probably swap a few modules around since it is actually pretty darn easy to access. (had it apart yesterday for cleaning and inspection) It is enticing to see a 5 year warranty on a GreenBean re-manufactured battery but most likely the old HO will die of other things before that 5 year warranty runs out anyway. Besides I can buy a LOT of Beer and Cigs for 2500 bones Haha Isn't that a cool looking battery pack? Hard to believe it still functions like new at 9yrs old and nearly 200k miles. Great job GM
