[0003] The existing leakage prevention early warning device of lead-acid battery is composed of leakage detection shell wrapped on the outer wall of lead-acid battery shell and various lead-acid battery shell detection elements located in the leakage detection shell, the shell of lead-acid battery is monitored in real time by these elements, and the water vapor content in the leakage detection shell is monitored.
[0004] Because electrolyte is composed of dilute sulfuric acid with certain content concentration, the substance has certain corrosiveness, and when these detection elements encounter electrolyte leakage, they cannot be discovered in time, so the detection elements will be damaged, and these detection elements need corresponding signal receiving system, which greatly increases the complexity of circuit, and the cost of detection and early warning system is also increased. UTILITY MODEL CONTENT
[0005] The technical problem to be solved by the utility model is that the existing leakage prevention early warning device of lead-acid battery mostly uses various detection sensors to determine its state, which greatly increases the complexity of circuit, and these sensors are relatively expensive and are easily corroded by electrolyte, thereby reducing their service life.

[0007] As an improvement, the lead-acid battery includes a battery shell, a plurality of electrode sheets located inside the battery shell, and a battery shell cover sealing the battery shell.
[0008] As improvement, the top of the battery shell cover is provided with several electrolyte filling openings connected by threaded plugs.
[0009] As improvement, the cavity of the leakage detection shell is connected with the bottom surface of the battery shell and the sealing plate of the battery shell cover by waterproof glue.
[0010] As improvement, the wire connected with the resistance sheet through the sealing plate is bare wire, and the wires connected with the positive and negative poles of the resistance sheet are connected with the resistance early warning device by parallel connection.
[0011] As improvement, the inside of the leakage detection shell is provided with an isolation block for isolating the two resistance sheets.
[0012] The device determines whether the lead-acid storage battery is broken by the resistance change of the resistance sheet after contacting the electrolyte, and no other corresponding electronic element structure and inductor is needed during measurement, so that the failure rate is minimized, the stability is improved, and the resistance sheet is low in price and low in cost.
