can you put that coil cell optima battery in an NA?

The cranking amps is 910.

 

I had one that had 1125 ca in my NA, it weighs a lot, but I got it for cheap and relocated it. So the answer is yes.

Also, I've heard bad things about the red-tops, but nothing bad about the yellow-tops.

 

The Yellow Top is a deep cycle battery. An automotive alternator does not provide the proper charge curve to charge it completely. Probably not an issue in the real world though.

A bigger issue is that Optima sucks. Over the past few years their quality has gone down the toilet. Look at Exide, or my personal favourite, Deka.

 

your alternator cant charge that battery completely get something with less cca

 

I have a red top in mine, its right around 800 i think. I love it, and its the only battery ive had that my FC cant kill
