I just replaced an 0ptima red top that I purchased nine years ago. Only replaced it because of low number on some test they did. Hope I didn't make a mistake, it didn't ever fail me. But I was told they are not as good as they were when I purchased mine. Guess I'll see how this Delco holds up.
The Optima Blue top in my Cole is the original battery, purchased in 2009, and spins my 565 like the plugs are out. Certainly has given me my moneys worth, definitely will replace at the first sign of weakness.
