It's under warranty so, the battery is no cost. Surprisingly the no AGM has a 80cca advantage and, is lighter. Theoretically, AGMs charge faster and are better for high drain applications.. we will see how long it lasts.
The charging system on these cars are pretty advanced, I think it can adapt to the new battery.

Buy a better battery. Buying the same POS that died in the first place is doing the same thing and expecting different results.

I also have a GM extended warranty so, I may never need to buy a battery. If I did I think I would try a Odyssey Battery.
