An exhaust pipe 3 communicating with the inside of the battery is provided in a recess 2 formed in the battery case lid 1, and a cap-shaped safety valve 4 made of an elastic material such as rubber is attached to the exhaust pipe 3. This safety valve 4
Is pressed by a cover lid 5 attached so as to cover the recess 2 so as not to come off from the exhaust pipe 3 when the battery is used. In the lead acid battery, when the cover 5 is first attached and the battery is initially charged, the electrolytic solution overflows from the exhaust stack 3 during charging and the recess 2 is formed.
Electrolyte was accumulated in the battery, which leaked out of the battery while the battery was in use, causing problems such as damage to external equipment.
In order to eliminate this problem, even if an attempt is made to send compressed air into the recess 2 to blow out the residual electrolytic solution, the gap between the lid 1 and the cover 5 is narrow, and compressed air can be sufficiently fed. There wasn't. Further, even if the lid or the cover is provided with one communication hole communicating with the recessed portion 2, the compressed air sent from the communication hole hits the exhaust pipe 3 and remains in the recessed portion 2 on the opposite side of the communication hole. The liquid could not be completely removed. Therefore, in the conventional method for manufacturing the lead storage battery described above, after the electrolytic solution is injected into the battery, the temporary cover is attached to the top surface of the concave portion 2 and the temporary cover is removed after charging, and the safety valve 4 is attached to the exhaust pipe 3. After mounting and removing the electrolytic solution remaining in the recessed portion 2, the cover 5 was attached.

もよい。Next, a method of manufacturing the sealed lead-acid battery having the above structure will be described with reference to FIGS. First,
A lid is attached to the battery case containing the pole group, and a sealed lead-acid battery having a terminal portion is prepared. Next, the electrolyte is injected from the exhaust tube 10 of this battery, the safety valve 8 is attached to the upper part of the exhaust tube 10, and the cover 7 is attached to the top surface of the recess 9. After that, this battery is charged for the first time. During the initial charging, as shown in FIG. 2, a gap is formed between the exhaust stack 10 and the safety valve 8, and the gas and the electrolytic solution in the battery reach the concave portion 9 through the gap, and the electrolytic solution is filled with the concave portion 9. Remains inside. When the initial charging is completed, the safety valve 8 comes into close contact with the outer wall of the exhaust stack 10 as shown in FIG. 3, and the inside of the battery is shut off from the outside. In this state, the pads 11a and 11b are put on the communication holes 7a and 7b of the cover 7,
Cleaning water is injected into the recess 9 from the communication holes 7a and 7b through the pads 11a and 11b. Next, the pad 11a
Compressed air is sent into the recess 9 from the one communication hole 7a through the inside. Then, the cleaning water and the electrolytic solution in the concave portion 9 are discharged to the outside of the battery together with the compressed air through the gap between the lid 6 and the cover 7. Next, compressed air is sent from the other communication hole 7a into the concave portion 9 through the pad 11b,
The washing water and the electrolytic solution are discharged to the outside of the battery in the same manner as above. In this way, the compressed air is alternately supplied from the pads 11a and 11b so that the cleaning water and the electrolytic solution do not remain in the concave portion 9, and the automatic cleaning is performed. In addition, the communication holes 7a and 7b of the present embodiment.
