What's the best modern battery for my Duster?

I have had excellent luck with NAPA batteries for about 20 years now. I don't know who makes them, but they are good. DON'T buy a Walmart or Sams battery. I think the brand is Eveready. I have had a few and had bad luck with them.
Also, sign up for sale Emails from NAPA, and you will get 20 or 25% off sale Emails all the time. That is the best time to buy a battery.
