Batteries going bad is NOT a Hummer H3 option; it is a free option on many cars, GM and other manufacturers. The rate of battery failure on the H3 is the same as on any GM vehicle, and from comparing notes in the auto industry, it is the same on any major brand. For all of you who have had one or two batteries, I don't know of anyone personally, who has replaced a battery in the first three years. Factory installed batteries meet manufacturers requirements, but that does not mean they are the greatest batteries made.
I did replace one in the first year of a vehicle's life, but it was my 03 Jeep Wrangler.
Now, if my battery does go dead, I will replace with an optima.
