My 2001 Ranger still has the OEM battery.<br />Although I am not having any trouble, I think I'm on borrowed time.<br /><br />I was looking at those 'Optima' batteries.... Anyone have one? Are they worth it? What are the advantages?<br /><br />I don't have any complaints on the OEM conventional battery... I'd just like to know what others have had good luck with. <br /><br />The only other battery I've ever used in my other cars is the Sears Die-Hard with no problems.<br /><br /><br />H.
