The battery Varta E24 is a classic lead-acid battery known for its reliability and relatively long lifespan. Its capacity is 70 Ah, and the maximum starting current is 630 amperes. The pole layout 1 means that the positive pole (+) is located on the left 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.
