    EFB technology in the Bosch S4 EFB battery: For passenger cars with start/stop system

    In EFB technology, the positive plate is coated with so-called polyester scrim. This gives the active material additional grip on the plate. Deep cycle resistance is then greater than in traditional batteries, and the battery also remains ready for operation when subject to strong vibrations.

    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.
