I've been searching for a while now and though people recommend an Optima battery they don't say which model. I know that it needs a vent/vent tube, but can anyone give me a more definite answer?

i've owned one in the past for another car...but I don't believe Optimum batts come in different shapes and the terminals may not be in the correct position.

I have always used Yellow.
You can put them in any position (not talking about polarities) even up side down , without any problems.
No vent tubes. They are completely sealed.

This is getting frustrating. It seems like everybody uses a different one. so far I have gotten yellow top, red top, vented and not vented.

I guess it doesn't really matter.
