はなく弧状でもよい。In the drawing, (1) is divided into six cell chambers (3) by the partition wall (2), and the electrode plate group (4) is housed in each cell chamber (3) and connected in series by connecting the cells. The connected monoblock storage battery case is shown, and a single common battery cover (5) is formed on the upper surface of the opening of the case (1) by a conventional method to form a monoblock storage battery. The lid (5) corresponds to each of the cell chambers (3), and a liquid injection port is provided for each.
(6), on the lower surface of the rim, a cylindrical upper limit liquid level indicator (7) with the lower end (7a) positioned corresponding to the upper limit of the specified liquid level of the electrolytic solution is projected downwardly. , The upper part of the indicator (7) is provided with a thread (8a) on its inner periphery to form a cylinder (8) for mounting the liquid mouth plug,
A liquid mouth plug (9) was detachably attached to this. In other words,
In the illustrated example, a tubular indicator (7) is provided at the lower end of the liquid mouth plug attachment tubular body (8), but the indicator (7) does not need to be tubular and may be arcuate. Good.

Apply the liquid port plug (9) to the liquid injection port (6). During use of the storage battery, the electrolytic solution decreases, and as shown in the drawing, when the upper limit U to the lower limit D of the specified liquid level is reached, the electrolyte is replenished to the upper limit by the above method and used again. As a practical matter, in a storage battery equipped with the indicator (7), the electrolytic solution level fluctuates due to vibration due to transportation of the battery or a decrease in the amount of the electrolytic solution, and the battery often separates from the lower end of the indicator (7). However, if this overlaps with the case where high voltage leaks to the battery case or lid or when static electricity is charged, a spark is generated between the indicator (7) and the electrolyte surface, and the battery case or lid is scratched. There is a danger such as.
