I believe the Optima batteries are basically one size fits all, with some differences. The red top, the most common in use, has a variation that has side as well as top posts. The blue top is intended for marine use, though not limited to that, and the yellow top is a deep cycle version intended for relatively lighter drain than starting or winching, but over a longer period of time before recharging is necessary. Most people I know use the red top.
Actually, the yellow top is designed for things like winching.
From Optima's site:

If your vehicle has a lot of accessories like running lights, high-performance stereo/AV system, winches, or hydraulics, your vehicle demands more from its battery. OPTIMA YellowTOP batteries provide the extra performance and deep cycling capability that your vehicle demands.
IIRC, they will not warranty a red top if it has been used for deep cycle activities.
