Enhanced Flooded Batteries were developed for use in stop-start vehicles. The reduced cost of manufacturing EFBs is attractive for manufacturers in order to help keep overall new vehicle production costs down. The EFB design incorporates a porous fibre material, sometimes called "scrim", along with plates that are thicker than a conventional flooded battery. The use of low pressure contact material on the plates of EFBs retains the active material and improves their cycle performance which is necessary for stop-start applications. Examples of vehicles using an EFB include the Mazda CX-5, Subaru XV and the Ford Fiesta ECOnetic.
