After 10 yrs. the Yuasa YTZ10S in my 2001 F4i finally gave up. Considering the exceptionally long life I got out of this battery I'd like to replace it with the exact same product. In shopping for a new one I found several equivalent size models with prices ranging from $60 to $120 all with 1 year warrantys. The specs on the most expensive ones say they are made by companies sub contracted by Yausa but I'm wondering if I could get 10 years out of them. Any recommendations ?
