Then, the pull block 5 is pulled to draw the storage box 3 out of the bottom plate 1. Then, the connecting wires and other equipment in the storage box 3 are connected to the battery charge and discharge tester 2, and the battery charge and discharge tester 2 can be used normally. When the battery charge and discharge tester 2 completes the test of the lithium-ion battery, the connecting wires and other equipment are removed from the battery charge and discharge tester 2, and then put into the storage box 3. When the connecting wires and other equipment are all put into the storage box 3, the storage box 3 is put back into the bottom plate 1, so that the connecting wires and other equipment can be stored, and the battery charge and discharge The related equipment needed by the electric tester 2 will not be far away from the surroundings of the battery charge and discharge tester 2, which is convenient for the subsequent search and use of the related equipment of the battery charge and discharge tester 2.
