The utility model discloses a soft package battery sealing performance testing device, which is characterized in that a transverse support plate is arranged in a cabinet body, a battery pack is arranged on the support plate, a charge and discharge tester for carrying out charge and discharge tests on the battery pack is arranged in the cabinet body, an electric hydraulic push rod is arranged at a position, corresponding to the battery pack, of the top of the cabinet body, and the electric hydraulic push rod is connected with the battery pack. An extrusion plate is arranged at the end part of the electric hydraulic push rod; the air pressure change in the cabinet body is detected through the air pressure sensor, when the air pressure in the cabinet body rises, the swelling battery pack leaks air, and the sealing performance of the battery pack can be judged to be poor, and when the air pressure in the cabinet body does not change, the swelling battery pack does not leak air, and the sealing performance of the
