Battery with indication function

The invention discloses a battery with an indication function. The battery comprises a housing, a negative plate, an electrolyte, a cell and a positive electrode terminal. The interior of the housingis divided into two cavities through a liquid sealing plate. The electrolyte is located in the cavity close to one side of the negative plate, and a transversely arranged conductive spring is arrangedin the other cavity. One end of the conductive spring makes contact with the cell, and the other end of the conductive spring is connected with a transversely arranged positive pole, wherein the positive pole is of a hollow structure, and the positive pole is connected with the positive electrode terminal through the transversely arranged spring. The positive electrode terminal is inserted into the positive pole and is in sliding connection with the positive pole. A conductive layer is arranged on the inner wall of the positive pole, a conductive sliding block is fixedly connected to the sidewall of the outer side of
