Pair of wally's, group 31. I'm fussy about batteries but only had Walmart to choose from. Were for my boat but it's beached now and doesn't need so much oomph anyway.
Pair of Wally's group 24s next spring for the boat (they be pretty darned good turns out) but a better alternator incoming for the truck. Even my shop charger takes hours to bring 31s to a saturated charge. No way this dinky toy original alternator's gonna handle life out on the frozen wastelands of the Cariboo. Especially if I crank the original ford am radio!
Over all the various battery threads here and on FTE over the years, it's reported over and over that lead acid batteries are only made by 2 or at the most 3 companies and that the guys doing assembly would slap different stickers on the same run of batts. Walmart, Sears, Costco, NAPA, Orielly... apparently all come from the same manufacturers with essentially the same internals.
The point is it's little wonder that Interstate Economy and Walmart batts have very similar performance as the Sears, Interstate or NAPA stuff. The biggest difference seems to be the price.
This is further supported by a few test articles I've found that had no clear winner of the brands tested, but one form factor Die Hard would perform best while a Walmart cheap-o in a different form factor would win that category. Pretty interesting stuff, and I'm sure there are exceptions but that's the general idea.
