I had 3 lead acid car batts reveal weak starting last year. An Eye-opener. Used to get 10-years in the 455 Pontiacs with Hi-TQ Delco Starters. 2-year life is an embarrasing indicator.
My study on car Batts showed differing brands had identical case molds for same case size, like a Diehard, even the old batts that crapped, So I gave up on Batt quality and bought whatever Silver-grade in O'Rielly'sAdvancedZone sold.
Notable hopefuls (but not for me); Braille, AC-Delco, and all thee above.
$15-$18 core return at Advanced autoZone means the yard sale core for a dollar is a wise buy,
