Yeah, I decided to just go with an interstate battery. Anyway, what I'm really looking for now is the size of the ring terminals that connect the ground from the battery to the motor, and the positive to the solenoid. Are they 1/4" 3/8" or what?The factory cables are fine performance wise. Now if they are frayed or corroded, I would change them to factory replacement cables. The gauge of the factory cables is more than adequate. As far as the battery, it has nothing to do with the alternator. I had Optima batteries back in like 1992, before they were even sold for cars. I like the Optimas, and the modern tech, but to be honest, nothing works as well on a daily driver as a regular factory style Nickel Cadmium. Don't get wrapped around the wire about the brand of the battery. There are only like 3 companies left that make nicads for cars, and every store just slaps their sticker on them.
