Best Battery? Options

[ExSane]

I don't know which battery to get. My brother told me that I needed a better battery. I'm running on Duralast battery. Brand new, just got it like about 4 months ago. Which battery is best for like overall? Including sound, performance, etc.

As alot of people notice, not all of my electrical parts of my car get enough power. They steal each other's power left and right. Like for example, not all my bulbs light up in the back when I press on brake. They all work, but not all of them light up. Another example is when I turn on my headlights, my interior including my gauge cluster lights dimm down by 50%! I need a battery that can give my whole car full power. Or do I need a better Alternator?

thas not your battery.
its either bad connections (corroded terminals) or a bad or going bad alternator.

anyone have problems with their optima battery?

when I first got mine, it went bad in 1 month.
now it seems to be dying again..(1 year) I haven't had it tested yet, but my amp meter shows my altinator is charging, and I don't see a drain when the car is off.. i'm guessing the battery went bad... again

which style optima are you useing?
red or yellow top?

the red is a "starting" battery
the yellow is a deep cycle, which will go dead if its not kept charged.
