The Lucas LE249 battery is a battery made using EFB (Enhanced Flooded Battery) technology. The battery capacity is 80 Ah, and the starting current is 740 A. The pole layout 0 means that the positive pole (+) is located on the right side of the battery, looking from the terminal side. B1 mounting involves the use of a strip located at the bottom of the battery casing, along its longer sides. This enables solid fastening of the battery to the surface with clamps or mounting brackets, effectively preventing it from shifting.
