I have an '05 with 96k miles and have no battery issues. Whenever I start it, the battery works great! I think it's mainly due to the fact that my alternator is powered by the 6.0 liter V-8 engine under the hood of my Hummer H2, which cranks out 325 horsepower. This power is also useful when passing malfunctioning hybrids on the interstate, hurdling my 9,000 pound vehicle towards my destination in a timely and oh, so comfortable fashion. I wish you all luck with your respective car troubles.
