Optima's are great as long as you keep them charged. I have seen many go over 10 years...
One of my blue tops is 10 1/2 years old. The other one bought at the same time lasted a week, and never could receive a full charge. It's replacement lasted barely 3 years and a couple weeks. The Interstate I replaced it with is 7 1/2 years old. They've gotten LOTS and LOTS and LOTS of use in my boat when I go fishing almost every day.

-Henry David Thoreau
Men and fish are alike. They both get into trouble when they open their mouths
