Anyone use this type of battery???

Any testimonials....
Im limited to space of group 24 but looking for more amps and longevity..

These seem to give you group 27 & 31 features in the same size as group 24

Any thoughts...

I have three Optima's (blue tops I think) in my Island Runner and will never buy another reguler battery again. 4 years old and I have never put a charger on them. The boat has sat for a couple months in the winter and they still cranked with no problem. I have also drained the slave battery, with a left on light, two times and the motors charged it up while running out and it never gave me a problem.

the guys at the worldcat website swear by them...
