No joke, that is all I used when I worked there in the early 2000s. And the old yellow "MAXX" batteries lasted forever. I put a couple in my dad's company vehicles and they lasted 7 or 8 years. And I had one that lasted 6 in my old Blazer, and it was shaken and knocked around, run dead a few times. But after a charge would be fine again.
That was my experience with Optima yellow tops in the early 2000s. My 02 Tahoe had yellow tops (eventually dual yellow tops) that lasted almost 8 years first round, 4 or 5 on the second round, and just out of warranty the last time before I got the 09.
Manufacturer quality is not the same. IMHO, as the technology improved it allowed the companies to know how to build them to guarantee most last through their warranty, but not significantly exceed it so you’d need another.
And also IMHO, while someone could probably also do a 48 or 60 month battery at a premium price, I’ll bet their research indicated:
1) Not enough people would buy them at the same time-adjusted profit margin, and
2) There’s a higher risk that temperature extremes and short distance driving would cause premature failure and warranty claims.
