anyone have any experiences using one?

 

I have one. Not sure what you want to know though.

 

How much, where did you get it (or where to get best price), and which model?

 

Does this battery fit in the s2k?

 

calm down everybody.

CCA 500
model Optima
group size 51

 

what i mean is do they last a lot longer, give "more" power, what r they good for, etc?

thnks

 

The yellow top is a deep cycle battery - would be better put to use if you have a demanding audio system. If you are stock, you would be better of getting the red top - its cheaper too!

IIRC you need to make sure you get the 51R as this is the reverse poles battery - otherwise your cables wont reach!

 

I got one recently, I love how I can wash my car and crank my stereo, and sill start the car when I'm done

 

Here ya go~
