There are "good" batteries and "not so good" batteries. Trojan, Johnson, Deka/East Penn, for example, all know how to build a good battery. But that doesn’t mean that every battery they build is equally good, or equally suited for the service you intend. For example, I’m using Trojan L-16 6-volt batteries. They make several different batteries, in several different product lines, that all fit that specification. The AH ratings vary from about 370 to 450, so I would guess that there are differences that go beyond just the capacity. So even going directly to the manufacturers will require research and some guesswork.
As Minnewaska points out, when you add a distributor that is private-labeling "something" from "somebody," you need to do a lot more research to know what’s on the shelf.
