Little by little im noticing my 2013 HD 6.0 crank & start up weaker & weaker. The battery is atleast a couple years old & I'm willing to bet it's time for a new one. I definitely want an AGM battery. I was thinking about picking up one of those Optima yellow or red top batteries (I forget which one I was looking at getting) but numerous people at this point have told me there's way better options out there, Optima batteries are over hyped & not as good now as they once were.. What's a good quality, dependable AGM battery that will last?? If it matters, the truck is driven daily & everyday I have a guaranteed 30 mile drive to work, then 30 miles back home.. So the truck is ran & used a good bit. It's never sitting unused for more than a day or 2 tops, if at all. Thanks in advance!
