Amaron FLO batteries are made in a QS 9000, ISO 14001 & TS 16949 certified plant using world class technology and stringent quality control parameters that make them last long, really long. Some of the other features that add to making the Amaron FLO so good: longest life, patented BIC vents for enhanced safety, the highest cranking power and a completely unnecessary 48-month warranty. Amaron is the only battery that contains the patented Silven X alloy. And that’s what gives it the power to last long, really long. Amaron AAM FL 550113042 is completly different from Amaron FL 550114042 except AH.
