I've never heard of them before, where did you buy from?

 

I got a question, why are the Optima Batteries so highly rated even tho it seems like the CCA is less than a standard Bosch?

 

I just picked mine up from local parts store. They have several different kinds, all with different colored tops.

A red top is generally what's used in automotive, it's gauranteed sealed, can be mounted sidewise, or even upside down. The CCA is pretty good but what's best about them is the longevity. I've ran one for close to 5 years in my daily driver with no issues. There's a variety of reasons they cost more, just google it as I can't recall them all off top of my head. lol

A Yellow top is a deep cycle battery, even higher CCA rating but those are generally used in marine or also automotive if running a very large electrical capacity. As in a massive aftermarker stereo with capacitators, amps, subs, ect ect....

And then there's a blue top but I dunno which one that does. lol

 

ok well thanks for the info, i just really wanted to know the base to these things. Ive never heard of them, and wondered why they were more expensive than any other battery. And that basically answers my question lol
