Eddie, I used to deliver car batteries to our private label dealers in the late '80s - early '90s. We also handled Motorcraft replacement batteries for the Ford dealers. The OE Motorcraft batteries carried a 1 year warranty, and many didn't make it much past that. The replacements had a 5 year warranty, and I don't recall warrantying many, but the dealers may have warranteed them without going back through us. Of course that was 20 years ago.
In the '70s, Firestone came out with their "Forever Battery". JC Penney's sold a version of it too. The slogan was "The last battery your car will ever need!" I bought one for my '74 Ranchero, probably to replace the original. Turned out "forever" was about a year and a half. I'm not sure they were on the market that long. I know I didn't want another one. Oh, and I finally parked the Ranchero in 2005, so the "Forever" was definitely not the last battery it ever needed.
