Get a 94R Interstate battery from Costco, or try Duracell from Sam's Club. They come with a three year replacement warranty. There's also one on Amazon for $160 from ACDelco. It's listed as from USA with a three year warranty. I would find the least expensive with the best warranty, just make sure it's an AGM battery.Anyone have a recommendation on a good upgraded main batt? Going to delete the stupid aux batt soon and figured I would upgrade the main since it will be the only battery and its 3 years old. Just started looking….any other options out there? Am I looking at the correct size/group?
2020 gasser, fyi.
