I want to buy at Optima Yellow top on Ebay anyone know the size number if there is any. I heard Optima are the best battery and I need a new one so I guess Ill get one. so please reply

 

Careful of the Ebay Optima's. Both the one's I bought were dead within a week.

I went with the Exide version of the Optima. A lot of other battery companies are now selling the spiral-wound totally sealed batteries in their higher-end models.
