i HAVE 3 oPTIMA'S
1 red top for my truck, going on 4th year
1 blue top for the boat, first year, but it will go a week of vacation on the boat with lights, stereo, fish finder, and outboard 2 stroke before it even shows signs of getting weak.
1 red top, back up for boat, on 4th year.
I had one Optima go bad on me after 2 years, problem was my old electric fan, killed it. Optima replaced it for $20.
Optima's are like K&N's, if you care youshould have one.
I am lucky I get them cheap since my buddy works there, but still they can be mounted upside down, they are tiny, they last forever, and they just outperform all the other batteries I have tried, if it;s a snowmobile, a tractor, a car, or a superduty, it should have an Optima.
