Stereo & Electronics - Which Optima battery?

Which Optima Battery fits in my car? Is it the 75/35 Redtop and does it fit with the stock batteryholder? Thanks...

i know that one fit my 99ss and the 02 i have now i don't think the firebird is different. BUT i could be wrong :) mario

Red is lighter and smalle then the yellow.
Yellow top has more capacity and is usually for stereo applications

yellow top all the way. if youre gonna put a red top in there, you might as well get a no name brand and save some bucks. the yellow top is deep cycle, so you can discharge and recharge over 500 times. it will fit, but min is touching the a/c line. its worth it, and it looks nice.

What do you base that on? Strictly performance wise a red-top will do what you need and not add considerable weight. The yellow-tops are nice, but overkill for some applications. Please explain.......

Straight from Optima
"red top under hood or as cars only battery"
" yellow as a car audio battery or 2nd battery"
" if there are two batterys use a isolator" so they both can charge the samebut be seperate"
"and trickle charge it when it sits for long times"

I have had over a dozen (no joke had them lined up in the living room) yellow top batterys, all died whent red no problems so far. This is my only battery.

I have bought a redtop... Thanks for the reply.

Good choice, I have one and it fits perfectly, runs amazingly. BTW whoever said it wasn't, the Red Top IS a deep cycle battery, too. Again, good choice.
