An explosion-proof filter is installed to prevent the gas generated by the valve and external fire point from igniting and exploding inside the battery. In addition, for ready-to-use sealed storage batteries that require injection of liquid immediately before use in order to prevent self-discharge and deterioration of the electrode plates, separate check valves and explosion-proof filters are required for liquid injection. A liquid outlet plug must also be provided.
