I currently have an optima yellow top under my hood after I went through 2 red tops. I actually had the yellow top in the trunk and the red top under the hood connected through an isolator/relay. Unfortunately, the red top did not like that and ended up prematurely getting killed.

Now I've heard of EFX batteries and I was thinking about getting one. Reason being is that they are red in colour which will match the scheme of my car. Does anyone have any experience and how they compare with optima?
