    The MotoBatt line of batteries is revolutionary in that they reduced 184 OEM part numbers down to just 34 utilizing their patented QuadFlex Advanced AGM technology. MotoBatt uses more lead per battery allowing them to have higher cold cranking amps (CCA) and amp hour capacity (AH). Typically, those two numbers work inverse to each other. In other words, you would need to lower AH to increase CCA and lower CCA to increase AH, but as you can see by the chart below the MBTX9U motorcycle battery using their advanced AGM technology has managed to increase both numbers.

    This Motobatt MBTX9U replacement battery comes with 4 Quadflex terminals and 1 spacer to adjust the desired height of the battery.

    Every MotoBatt AGM battery comes with a 2 year full replacement battery.
