Bosch S3/S4/S5 battery with PowerFrame® technology

  • Product information

    S5/S4/S3 with PowerFrame® technology: Optimum starting performance for every passenger ca

    With its S5, S4 and S3 batteries, Bosch offers three made-to-measure battery lines for a great variety of requirements and vehicle types. The grid with special PowerFrame ® technology – responsible for optimum electricity flow, lower corrosion and a longer service life – is crucial for the performance and reliability of these Bosch batteries. The S5, S4 and S3 therefore satisfy the stringent international quality requirements for cold starting performance and capacity.

    PowerFrame® technology: More power right from the start

    The 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 resistant to corrosion.

    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 cycle 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.
