I've had two Optima's. The "old Optima" lasted 6-7 years with some abuse. I was very happy. During that time it sounds like Optima went through quality problems... then got better. I bought a "new Optima" about 3 years ago and it has been fine.

That said, I use Optima only on the battery in trunk to prevent leaks and a rotted trunk floor. In DD's and other projects, Walmart or parts store "better" or "best" has served me well.
