MotoBatt QuadFlex batteries offer the best balance between AH (ampere hours) and CCA (Cold Cranking Amps -18C). MotoBatt achieved this by increasing the size of the internal plates, utilizing the unused space found in other batteries.
This is made possible through a patented innovated cell connection system. Additionally, MotoBatt enhanced the thickness of the grid, the density of the paste, and the weight (content) of the active material to maximize the capacity allowed by its size, making the QuadFlex revolutionary to the Battery Market.
