Oreilly batteries are usually East Penn. There are a few exceptions where Johnson Controls make them, but the part number ends in a J. From memory Johnson controls makes Autozone and Walmart batteries as well as Optima now. Our Kubota tractor has a battery from Tractor Supply in it. Priced closely to what Walmart sells them for and a 2 year warranty. Other than that when I was at a Nissan dealership Interstate supplied our batteries in a black case with a Nissan label. Once they ran out of Nissan labeled units and relabeled Toyota labeled batteries to restock our shelf. They were straight garbage. On the other hand the Deep Cycles on my travel trailer are Interstate and they have been on it since I bought it in 2015. They are still alive. I think the big difference there is I am able to keep the batteries topped off with electrolyte on it unlike the sealed garbage. At one time I had the best luck with Johnson Controls AGM batteries (Autozone Duralast Platinums). My Express van got 6 years out of the first one. Then they went down hill. About the same time Autozone eliminated the ProRata warranty that was 8 years on them and dropped to a straight 3 year warranty. They were not worth the money after that, considering a normal lead acid would last the same (post PCM controlling the alternator) for half as much.
PCM controlling the alternator in both my Express and Tahoe nearly doubled how long a normal lead acid maint free battery lasted in them. Also eliminates having to trickle charge a battery.
