Why a new Battery?
 

Why is it that people buy these big ass batteries? Does it actually improve performance? If so how, and what actually is effected? I really want to know.:)

some just upgrade there batteries to the Optima redtop batteries. I've heard they are better batteries when you plan on adding alot of electronic things to your car.

Doh!
 

I should have posted this in another section!! can someone move it please!!:D
