PURPOSE:To shorten the injection time and save the labor without damaging an isolator by boring a hole on the side of a vacuum injecting jig provided with a liquid level sensor. CONSTITUTION:A liquid injecting jig 5 provided with a liquid level sensor 17 is fitted to the liquid injecting port 7 of a battery 1, a liquid injecting solenoid valve 10 is closed and a vacuum switching solenoid valve 14 is opened, then the battery 1 and the jig 5 are maintained vacuum. Next, when the solenoid valve 10 is opened, an electrolyte in a container 9 passes a cylinder 15 penetrating the jig 5 and is poured on the upper whole body of the battery 1 through a hole 16 bored on the side of the cylinder 15, thus the electrolyte is injected into the battery in a short time without damaging isolating plates such as electrode plates. Accordingly, the injection time is shortened and the labor is saved without damaging isolators. |
