Which ones are the newest?
I looked at the old one my neighbor still had in the back of his truck and I could not find a "Made In"
Thou the larger sticker on the front of both batteries say "Professional" only the old one had it on the top sticker the new one as you could see does not say it on the top stickers...
the mystery deepens....

My problem occured again. This time the truck sat for 6 days without me using it. I tried to start it on Sunday afternoon and the battery was dead. I followed the dealers directions and call their 24 hour service. They towed it from my house Sunday and as of today (Thursday) they still have not found the problem. The good news is they are not giving up and they did offer me a rental car. More to come.

Keep us updated, I suspect they do a few re-flashes of software to ensure that everything is shutting down like its supposed to when the battery reaches a certain level of discharge...

Did you ever solve it?
So a few weeks ago, my 07 Tahoe needed a jump start. The vehicle wasn't driven for about 12 days. The battery is new, was purchased back in March 2010. Its garaged kept, not exposed to totally cold outside temps here in Central VA. I understand 12 days is sort of a long time not to drive a vehicle and expect the battery to hold charge. The car is driven about 3 times a week mostly on long drives 1 - 1.5 hr (1 way) trips about 130 miles total.
Today I started the car and it was very slightly hesitant to start, it just wasnt a nice crisp start. The car was last driven on 12/04. I believe there was a service bulletin a while ago about the 07 Tahoes having battery issues or something about the BCM constantly running, and I think the fix was a s/w update. I believe my s/w is up to date on the car, but one thing that keeps happening is that when the battery dies, my engine hours are resetting back to zero. I wonder if there is some sort of slow drain or maybe my alternator is not up to par. I had the battery checked and it passed. My next step is to have the alternator tested.
Not sure what else could be the cause. If the car loses power like mine, will it lose the s/w updates that happened in the past?
Tthanks for any input!

Consider replacing both your battery cables the negative and the positive cable up to the meg-fuse. Both of my cables on my 07 appeared fine but when removed and connected to a meter the cables would open when flexed...
This resolved my random door locking, HVAC resets and occasional traction control errors, not to mention the random no start acting like a dead battery.
Another sign was the head lights dimming when the AC /cooling fans kicked on.

Thank you!
thanks so much for the suggestion. I’ve also had issues with all of what you’ve mentioned.....a/c quits working randomly, traction indicator issues, door locks won’t work for a few day, and power driver’s seat won’t move.
Where should I go to get something let like this done?
thanks again!

Any reputable auto repair shop can do the cables. Each cable is ~$ 50.00 or so, installation time is probably about 1.5 to 2 hrs. If you are able to do the repairs yourself, I would consider this a fairly easy repair. I would recommend checkout out Youtube videos of the process even if you have it done at a shop, just so you know what is being done.
