BOSCH Battery 85Ah 800A R+ (efb/starting)

Along with the increase in technological advancement in vehicles, the number of electric receivers responsible for comfort and safety increases. Bosch S4 is a reliable source of power for compact cars, middle class and those with a higher standard of equipment.

Bosch's S4E EFB (Enhanced Flooded Battery) technology bridges the gap between traditional starter batteries and AGM technology. The performance of the batteries in this technology proves useful in cars with Start / Stop systems. High resistance to cyclic operation ensures adequate power reserves when restarting the vehicle. The high amperage also meets the requirements of vehicles with a large number of electric consumers. In EFB technology, the positive plate is covered with a layer of polyester, which improves resistance to cyclic operation.

PowerFrame technology

The novelty of the Powerframe technology consists in the use of extrusion in place of the existing casting technologies and the cutting and stretching of the grate.

Patented grille made in PowerFrame technology ensures optimal current flow and reduced susceptibility to corrosion. The construction of a lead grille with shortened current paths ensures faster energy flow and current consumption, ensuring reliable engine start-up and extended battery life. A special lead alloy increases corrosion resistance and ensures a low discharge rate.
