They were ok. My buddy had one for his 68 Chevelle and it lasted for several years. I do know the newer ones last longer due to the newer technology.
Big thing with these batteries is to disconnect the negative terminal when the car is sitting not in use. I always do this over winter storage and never use a battery tender and my batteries have always been fine. Plus this kills all power in the event something shorts and starts a fire. Several of my cars have the original wire harnesses, plus I always have a fire extinguisher in the car.
The last battery I bought for my Chevelle at Jim's in Youngstown still works fine. When I bought it the guy that put it together told me the big thing was disconnecting the negative cable when not in use more so than using the tender. I have always done that anyhow so I was used to it.
