Century Marathoner   Century Marathoner is a heavier duty MF Battery compared to ordinary MF batteries， as a result of the addition of more active material and utilization of thicker grids. The additional active materials enable the plates to produce more power under an optimized material utilization rate while the mechanical properties of the plate is enhanced by the new design and thicker grids; ensuring that plates have a higher corrosion resistance.  Better Grid Design  Century Marathoner utilizes the tried and tested Expanded Positive and negative Lead-Calcium-Tin Alloy Grids， that allow the grids of the plates to have finer grain structure vs cast grids. The finer grain structure minimizes the sulfuric acid’s ability to corrode the “hollow spaces in the grid structure” and the result is a longer testing grid / longer battery service life.   Low Water Consumption Rate  Thanks to its Lead Calcium-Tin alloy & Labyrinth design and gas liquid recombination cover; the Marathoner has a lower water loss and achieves a longer service life.  RAMCAR FIBREX TECHNOLOGY  It enhances the cohesiveness of active material components and allow active material compounds to freely expand. It enables contracts to its maximum during the charging and discharging process without breaking the bonds holding them together. This results in a more complete reaction of the active materials and acid; generating higher and consistent power.  Vibration Pads  The Vibration pads act like ‘plastic springs” that are placed inside each cell of the battery， ensuring tighter element fit， resulting to higher vibration resistance.   Strap Protection  The strap protector serves as “shields” in the event that the plates experience vertical grid growth and preventing the grid and other battery parts to short circuit.
