does anyone here have an optima battery in their car instead of a regular battery? is it worth the money to get one, cuzz my car battery keeps on dying over night i have to jump start it to get my car running. just wanna know how does optima battery compare to a regular battery. even if i do get one, would it be best to get the RED-top or YELLOW-top ones, since i know the yellow top is for car with aftermaket stereo system. i mean is it practical to get a yellow top over a red top when all i need is just to start my car, and not to listen to music when the car is not running?
