I have had my share of battery trouble through the years between racing cars and now boating. Once I stopped using Interstate batteries and switched to AC Delcos my battery problems are gone. I will use nothing but Delcos from here on out. I'm sure there are many other opinions out there but for the money I think you can't go wrong with them. BTW, I have a 2003 PT-175 and got only 2 years out of the Interstates that came with it.
