I have seen others here recommend the Costco battery for our JK's. Seems like it is for their deep cycle battery. I checked today and they offer a "Marine" model. Is this the same battery others have recommended? I noticed the warranty is not as long as is on their regular gel cell battery specified in their catalog (group 34). Am hoping those who recommended their battery will chime in here. Is this the battery you bought and how has it treated you?
