I used Optimas. They were fine. I changed to the Sam's Duracell AGM. I like them better.
ONE REASON I CHANGED .... I understand that Optima moved their plant to Mexico. The Duracell are made in USA and I like the specs better. There is a very helpful guy here that goes by Catfan name. I read a lot of his suggestions and saw logic to what he said to others so I moved away from the Optimas. Go ask him about them.
