Optimas are great batteries. I put a 34R? reverse post in my 986 just as soon as the original gave up the ghost. When I was restoring my old 911 I went through three or four flooded batteries over the course of several years. When I finally bought an Optima I never had another engine cranking issue due to a weak battery. And they don't spew acid all over your body work. After replacing two gas tank support pans in early cars I swore I'd never rely on a vented battery again. I've a friend with an Elise using a Braille battery and he's extremely proud of that energy source but has to keep in on a maintainer if he's not going to drive the Lotus for more than a week. Be thankful that we have room to use a nice large battery in the Boxster / Cayman series. Buy what you like but the Optima's are, in my opinion, amazing.
