I would rather buy Interstates. I seem to have good luck with them. But lost guy Walmart, I sure will work fine for most things.
Also, Wally Mart Cranking batts are only 850 ish amp. Merc 250 Pro XS spec to have 1000 amps as I recall, so I bought Interstate and were about the same price as I recall. My buddy buys the Walmart craking batts and he says it cranks is 250 merc just find and runs live wells and electronics etc.
