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.
On battery replacement, it is important to install EFB batteries again in passenger cars that were fitted with this type of battery when new. Otherwise, the function and positive effects of the start/stop system would be impaired. The battery service life would also be reduced.
