Flyin, agree 100%. Had original Yuasa original for over 9 years. Replaced with Deka agm in 09 before they were even popular. Last 3 years. Because of price at wholesaler I bought another one this time using maintainer and in basement. Again , little over 3 years. Found another Yausa lead acid will see what happens. Maybe I need to try a agm for my cars even those lead acid ones been working many years for me. Yea Right
