GC batteries are remarkable when properly constructed. Their electrolyte volume to active plate surface area side steps many potential issues. A GC with industrial .145" plates and paste would be awesome but that would come at a cost of high price and substantially lower capacity per footprint area.
However -
The manufacture of consistantly dependable GC batteries is an artform. The typical RVer does not even begin to approach the demands as needed on a golf course. But wanna be runners up become harder and harder to charge as time passes. They sulfate faster than a top of the line GC and in reality make a mockery of the supposed "savings" in the retail price.
None of the weaknesses of a bargain battery will show up under shallow occasional use. It's when batteries are cycled deeply and often that pretenders fall flat on their face. Positively false economic savings.
