2006 Solstice 2.4L
Went to the auto parts store where I got the battery from and they told me that they couldn't do an RMA/warranty replacement without charging and then testing the battery. They said they'd need a few hours, and after that time was up, I got a call and they said the battery tested totally working, so they wouldn't give me a replacement. I now have my battery from before all this, still at 12v, and the battery that was at 1.9v until today and is now at 12v, both in my possession.No security light? It should have been lit up solid. If it was blinking I would be concerned with an issue with the anti theft system.
That could have been a connection issue, it's hard to say for sure tho. Get the new battery and lets go from there.
