Hey folks, I'm looking at getting a Group 27 AGM 12v 100Ah battery. It will likely be kept floating the vast majority of its life. If I walk into a store, and they even have one in stock, I'll pay about double what I'd pay if I buy a UPG battery online.
How is this even possible? Is there that big of a difference in the batteries or am I somehow avoiding a core charge by purchasing online? Anybody have any experience with a UB121000 or similar battery?
