Abstract: An apparatus for filling a battery with electrolyte has an electrolyte feeding unit pivotally mounted on a body, an electrolyte filling port slidably installed within each of longitudinal holes of the case receiving unit, and a valve unit for opening the filling nozzle of the electrolyte filling port.
