Does that include KY jelly??? :Hump:
Most Diehards are built by "Johnson Controls". Same folks who build Interstate, Duralast, AC Delco, and probably 20 other brands[also the (n)Ever Start at WalMart]. The Platinum batteries are built by EnerSys, who also build their own Odyssey batteries.
While all these contract batteries aren't built to the same specifications, Johnson Controls has long been known for building "3/4 plate" batteries. These use plates shorter than industry standard, and a slightly stronger acid solution to develop the same amps as a properly built industry standard battery.
After years of selling them, product built by "East Penn" will always be my Go-To battery supplier. These are labeled "Exide" ,"Electro", NAPA, O'Riley Super Start, and dozens of others.
There are only about 4 actual manufacturers in the U.S.

See, I've had a totally different experience... We used to sell nothing but Exide at Belle Tire here in MI. I ran them in both vehicles (Grand Am and Vue) and the one in my Pontiac just shat out on me, no warning or anything. :blah: Swapped it with an Interstate (Which is all we will sell now) and never had an issue after that.
