Their is a backup battery system built into the On-Star module. It should never need replacing over the life of the vehicle.
Only if you have onstar. Some 2006 TB's have onstar, but most don't. It came standard in all GM vehicles as of 07. You probably have analog onstar which does not work anymore (not sure when that happened) but only the digital onstar works. If you have the analog and your in an accident onstar will try to connect but it wont work and possibly drain your battery. If you find out this is the case you may be able to upgrade to digital for a lot $$ or you can get it disabled at a Chevy dealership for free
