what's the best battery i can get under 100 bucks .

 

One that fits......

 

Best battery for what?

I'm pretty sure you can't get an Optima for under $100 so you might as well just get whatever they have at the auto parts store. It's just a battery.

 

yes i assumed i would be limited to an auto part store battery but they all can't be created equally which one makes a higher quality product ?????

 

Honestly, I've been driving for 2 years on a remanufactured Duralast (I think?) battery from Advance Auto Parts with no problems whatsoever. It's been fully drained and recharged 3 times (due to leaving the lights on twice, and the brake pedal switch stopper busting once and leaving my brake lights on) and it still performs like a brand new battery.

It cost me 30 bucks.

Oh, and this is all being used with a Sony 1000W (peak, idk the RMS rating) amp and 2 MA Audio 10" 350W (peak, once again idk the RMS rating) subwoofers. I have a capacitor now, but only because I got it in a deal with Danomatic93 when I bought the amp from him. The headlights don't dim when the bass hits, and they didn't dim before I had the capacitor either.

My alternator is new, but only because the bearing in my old one went bad. Even with the old 16-17 year old alternator, I still had no problems.

 

are those the guys that started selling head units at walmart.

 

I'm not sure what you mean. Are you talking about Duralast?

Duralast is a battery manufacturer. Dual might be the head units you are thinking of.

 

also if i put in a larger battery will there be any adverse effects ????
