Lead acid batteries

Why are these pile-o-crap batteries even produced anymore? Sure they are less $$ than an AGM battery. Bought a lead acid battery for my yard truck. 2 years later it went south. Not denying that an Optima is more $$ but have yet to have one last less than 8 years. Last one I replaced was almost ten years old....

Doug,my opine ( did retail parts 25 years, what a P.I.T.A..): most companies sell J.C.I.( Johnson Controls International).. That would be Auto zone/Carquest/Wally World/ Sears... They also bought Optima,some time back.The one battery I sold ( & personally used & liked ..) was a universal
optima style battery,similar to the Optima Red Top. You mentioned problems before,with the Harley batteries. Is this the issue, or is it the Ford diesel?..( In reference to my first sentence of this crappy statement: Retail battery prices have risen 20-30%, in the last three years..& the warranty has been shorted back.) My information, use it if you can...
