PROBLEM TO BE SOLVED: To provide an electrolyte filling device in which there is no splash of the electrolyte at the filling of the electrolyte and the electrolyte can be filled after the lead plate of the positive electrode and the lead plate of the upper lid are jointed. SOLUTION: The electrolyte filling device 40 comprises an enclosed chamber part 1 that houses in closed state the battery 10 of which the upper lid 10b is connected and the opening part 10a is formed, an electrolyte storage part 2 for storing the electrolyte, a pipe 3 for communicating between the enclosed chamber part 1 and the electrolyte storage part 2, and a piston shaft 4a for pumping out the electrolyte. By making negative pressure the internal pressure of the battery 10 that is not filled with the electrolyte, the electrolyte is pumped out from the electrolyte storage part 2 into the battery 10, and filling is started, then, after a prescribed time has elapsed, the internal pressure of the battery is changed to an intensified pressure, and the electrolyte is penetrated inside the electrode plates group in the battery 10, and the electrolyte is filled according to the penetration speed.
