    PowerFrame® technology in Bosch S5/S4/S3 batteries

    The grid is of crucial importance for a battery's performance and reliability. The patented PowerFrame® offers considerable advantages over conventional grids, and is responsible for an optimum flow of electricity.

    Bosch S5/S4/S3 batteries therefore impress with their outstanding starting power and longer service life.

    More power right from the start: Advantages of PowerFrame® technology

     

    Rigid grid frame

    Prevents grid growth and corrosion at the edges and so damage to the separator, or short circuits caused by the grid making contact with the negative plate.

     

    Stamped grid

    The rigid, precise structure ensures excellent adhesion of the active material to the grid and permits low-resistance, rapid charging and discharging of the battery. In contrast to conventional grids, there is no brittleness arising from mechanical deformation during production.

     

    Optimum grid structure

    More lead is applied to the areas subject to a higher load: the grid is more hard-wearing and resist

     

    Grid designed for optimum flow

    In this innovative design, the grid bars lead directly to the plate link. The low flow resistance ensures optimum conductivity and the fastest possible supply of power to the electrical device.

     

    The SAE J240 (75 °C) life test shows that

    The stamped grid (right) exhibits minimal corrosion with virtually no loss of conductivity. In the grid on the left, the material between the alloy grains has suffered corrosion, resulting in a weak flow of current and a shorter service life.
