Correct me if I'm wrong but I don't think you have an electric winch. I would get a red top Optima battery.
The yellow top is a deep cycle. Thats good for a 2nd battery that is used for a winch.
The red top is a standard battery. It doesn't like to be completely discharged. On the other hand if you have a 2nd battery for a winch you are better off with a yellow top. Those deep cycle batteries can be discharged all the way. Actually that's good for a deep cycle battery.
I'm not sure but I think the Optima batteries are too big for the OEM battery tray. you might want one of these trays:
