You can also get them at the higher end stereo shops around your town.

I bought mine at Sears though.

 

so uncle bubba, is it a good assumption then that its a fairly high failure rate then?

 

I have Optima Yellow Tops They work

 

I havent had a prob with my red tops yet and have some other friends running red and yellows with no issues.

 

I need to get mine tested to see if I have dropped a cell in them, I think that I might have and since I am still under warranty I would like to have them replaced, but i would pay the upgrade at the same time if it would be a upgrade from stock to red tops.

 

ok so does anyone know the model number or the group size of optimas i should be looking at?

OPTIMA Batteries

 

I'll have to look at my batteries or find the reciept. I got the size they had sitting on the shelf that was a higher amp rating than the recommended replacement. I guess the location of the battery posts is off a little; my battery cables barely reached, but it WORKS. I'm glad I got the "bigger" one.
