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.The Bosch S4 Blue are suited to cars with medium electrical demand such as air conditioning, heated seats, cruise control etc. These Bosch Batteries will normally be fitted to modern vehicles typically from 2000 onwards. The Bosch S5 Silver are suited to newer vehicles with higher electrical demands that come equipped with features such as parking sensors, trip computer, heated front windscreen etc. These Bosch Batteries are mainly for the latest high end vehicles and large diesel Engines. 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. If nobody is home or the courier does not feel its safe to leave securely, they will reattempt the following day. They normally do this 2 times and then return to the sender (us). Larger Commercial & Marine batteries which need to be sent via pallet may incur an extra postal charge.
