I don't remember the model number off the top of my head, but you can call the battery store and they should know. here's a link with stores they have in illinois,

Optima red tops are normally for just starting cars. But due to our larger engines, they aren't as effective.
Yellow tops are for stereo systems requiring extra batteries. They are more powerful than red tops, but are notorius for not starting well when it's cold. They are also known to leak, even though the whole point is that they aren't supposed to leak.
Blue tops I beleive are the same as yellow tops, but are supposed to be for marine applications.
