The invention discloses an anti-acid-leakage epoxy resin pouring-free valve control storage battery large cover, which comprises a large cover body, the large cover body comprises a positive electrode end and a negative electrode end, the positive electrode end and the negative electrode end are respectively provided with a pole column cavity, a pole column is arranged in each pole column cavity, and the cavity wall of each pole column cavity is provided with a plurality of grooves; a terminal cavity is arranged on one side of each pole cavity, a terminal is arranged in each terminal cavity, and a plurality of terminal grooves are formed in each terminal. Due to the staggered structural design of the terminal and the pole and the five concave-convex pit structures of the terminal, the phenomenon of acid leakage and acid leakage of the terminal is effectively eradicated; the structure is used for replacing a large cover using a straight-out terminal structure, so that the processing procedure is greatly simpli
