There are instances where -guaranteed- reliability are warranted. Like when a person is way the hell and gone remote boondocking on vacation and a bad battery virtually destroys the vacation ($3,000 vacation versus perhaps 185 dollars in cost of batteries)
I'll harp on this once again - Golf courses are cheapskates. They'll kill over a nickel. They can purchase any battery on the face of the earth but WHY OH WHY do most golf courses INSIST on Trojans? They are not sold to golf courses at a far cheaper rate than an Oxide or US Battery. Quite the opposite. They are a hell of a lot more expensive. Are the golf course management teams stupid? Some of the largest courses employ MBA accountants to analyze to the last freakin' penny how much a battery ACTUALLY COSTS over a given period of time. The TIME accumulated on hour meters versus the ELECTRIC BILL used to recharge the cars.
And courses almost to the last one specify Trojan. There has to be a reason why the choice of thousands of batteries narrows it to a few select brands (Crown is another choice but logistics favor the Trojan overwhelmingly).
I am noted for being a hell of a cheapskate. Being I am familiar with storage batteries and the inconvenience and overall cost of premature battery failure you could not suck me into buying the "Low Cost Leader" for love nor money. I am here in Mexico, and when I buy a battery I DEMAND RELIABILITY, because in the end, a cheap battery is going to end up screwing me to the barn door.
Some folks do not mind installing batteries, alternators, and starters with velcro fasteners and wing nuts. It's purely price and lifetime guarantee that matters to them. Wearing out tires returning garbage to the vendor never enters their mind.
I have a set of 2-volt batteries that have lasted 2-1/2 times as long as the "Industry Standard" but they cost 180% that of the lesser battery. It's not just the purchase price for me, it's the forklift and 18-wheeler needed to make them available for warranty. Did I mention the hassle and out of service factors?
So when someone insists on obtaining a battery with the best reputation, they have their reasons. Those reasons are absolutely just as valid as reasons given for purchasing the least expensive battery a person can find.
I respect both when the reasons are justified. But please don't try and compare a US Battery and Oxide or other low price leader with a Trojan, Crown or Rolls. They are batteries designed for a SPECIFIC market.
