Sonnak EFB

carbon boost 2.0

First invented by us in 2008, EFB batteries have come to play an increasingly crucial role for car manufacturers in order to reduce fuel consumption and emissions. Now we bring the latest OE generation to the aftermarket, featuring Carbon Boost 2.0.
The new Sonnak EFB battery supports all vehicles, with and without Start-Stop systems, which have high cycling requirements. When installed in cars with a Start-Stop system, Sonnak’s new EFB battery shows an unmatched energy recovery and exceptional dynamic charge acceptance. The battery also benefits from a longer overall lifespan, when installed in cars with conventional power train.
