The invention discloses a waste storage battery storage device. The waste storage battery storage device comprises a storage box provided with a door leaf. A rubber layer extending to the inner side wall is arranged on a bottom plate in the storage box, and a first liquid guiding mechanism is arranged on the rubber layer. A plurality of storage racks are arranged in the storage box, and elastic guiding sliding mechanisms are arranged between the two ends and the inner side wall of the storage racks. The storage racks are further provided with second liquid guiding mechanisms communicating withthe first liquid guiding mechanism. A top plate of the storage box is provided with a storage rack pushing and pulling mechanism. A ventilation mechanism communicating with the interior of the storage box is arranged on the outer side wall of the storage box. A storage rack guiding conveying seat is inserted in the end part of the storage box, the storage rack guiding conveying seat is internallyprovided with a liquid containing cavity and a liquid discharge tube communicating with the liquid containing cavity, and the liquid containing cavity further communicates with the first liquid guiding mechanism. The centralized and orderly closed storage of waste storage batteries is realized, and the purpose of centralized collection of a leaked electrolyte solution is achieved, so that the harmless storage of the waste storage batteries is realized, and the problems of corrosion of surrounding objects and environmental damage caused by electrolyte solution leakage are solved compared withthe prior art; meanwhile, potential safety hazards are greatly reduced; and in addition, the storage of the waste storage batteries according to classification and time is achieved, and later search is facilitated.
