Someone can correct me if I am wrong but Interstate not what it used to be either, thought they were bought out by Exide which ranks right up there with FVP as far as battery quality goes IMO. As stated by others in this post I too like the NOCO Genius chargers, use them at my shop, was turned on to them by a recommendation from a post on this site a few years ago. I will point out also that I've seen some funky things occur with batteries that are seemingly good and will cause issues that will make you go HUH.Marine battery is interstate.
