Description of the Related Art The concentration of dilute sulfuric acid as a chemical solution used in forming a battery case is lower than the concentration of dilute sulfuric acid as an electrolyte of a lead storage battery. The reason for this is that the use of low-concentration dilute sulfuric acid in the chemical conversion liquid improves the chemical conversion efficiency of the anode, and can reduce the time required for battery formation. Therefore, in the manufacture of a lead storage battery through the battery case formation process, a process of adjusting the sulfuric acid concentration of the electrolytic solution after the battery case formation process is required. So conventionally,
After the formation of the battery case, a part of the chemical solution was discharged, and dilute sulfuric acid adjusted to a higher concentration than the chemical solution was injected into the battery case to obtain an electrolytic solution having a predetermined sulfuric acid concentration and a predetermined amount.

量調整工程を簡略化することである。However, the conventional methods for adjusting the sulfuric acid concentration and liquid amount have the following disadvantages. (1) When trying to apply the conventional sulfuric acid concentration and liquid volume adjustment method to lead acid batteries of different models and models, especially lead acid batteries of different sulfuric acid concentrations in the electrolyte, the same number of models and models as above are required. Dilute sulfuric acid solutions of different concentrations and tanks containing them must be provided. Therefore, it is necessary to secure a large space for installing the tank. In addition, it is necessary to prepare many different concentrations of diluted sulfuric acid. (2) After discharging the chemical conversion liquid, the chemical conversion liquid is held in the battery case, particularly in the electrode plate and the separator. That is, there is a residual chemical solution. The amount of the residual chemical solution depends on the size, model and model of the battery case, that is, the number of electrode plates, the number of separators, the type of separator, and the like. Therefore, even if the lead acid batteries have the same sulfuric acid concentration (standard value) in the electrolytic solution, it is impossible to apply the conventional sulfuric acid concentration and liquid amount adjustment method described above if the size, model and model of the battery case are different. In view of the influence of the amount of the residual chemical solution, a large number of dilute sulfuric acid solutions having different concentrations and a tank containing the diluted sulfuric acid solution are required, which has the same problem as the disadvantage (1). The problem to be solved by the present invention is to simplify the process of adjusting the sulfuric acid concentration of the electrolyte and the amount of the electrolyte after the battery formation process for various types of lead-acid batteries.

る。Conventionally, the second diluted sulfuric acid and the third
Dilute sulfuric acid or dilute sulfuric acid corresponding to a mixed solution with water is required for the number and types of lead storage batteries. However, in the above-described configuration of the present invention, a diluted sulfuric acid having a desired concentration can be prepared by a mixing ratio of the second diluted sulfuric acid and the third diluted sulfuric acid or water. Therefore, for various types and types of lead-acid batteries, dilute sulfuric acid with a concentration suitable for each lead-acid battery is prepared, and the diluted sulfuric acid is placed in the battery case after formation of the battery case (for each type of lead-acid battery). An amount that can achieve the sulfuric acid concentration of the electrolytic solution can be injected. In the process of adjusting the sulfuric acid concentration and the amount of the electrolytic solution after the battery case formation process for various types of lead-acid batteries, only the second diluted sulfuric acid and the third diluted sulfuric acid or water are prepared, The number of the above-mentioned tanks is at least two, and the space for manufacturing can be saved. Also, there is no need to prepare many different concentrations of dilute sulfuric acid.
That is, it is possible to simplify the process of adjusting the sulfuric acid concentration and the amount of the electrolytic solution after the battery forming process for various types of lead storage batteries.

A 3R type lead storage battery will be described as an example. First, a required number of positive plates and negative plates are manufactured by a known method. Then, a positive electrode plate and a negative electrode plate are laminated via a flat glass fiber separator to constitute an electrode plate group, and the operations necessary for the subsequent production of a lead storage battery, for example, formation of a strap, electrode plates to a battery case , Insertion between cells, bonding process of battery lid and battery case, etc., before the battery case formation. Chemical solution during battery formation (No. 1)
Dilute sulfuric acid) has a specific gravity of 1.15 and an amount of 70 at 20 ° C.
Make it 0 ml. The charging operation is performed for 9 hours at 0.3 C with respect to the rated capacity of the lead storage battery at an ambient temperature of 25 ° C., and the battery case formation is completed. Thereafter, the lead storage battery is inverted for 60 seconds to discharge about 55% of the first diluted sulfuric acid. Then the specific gravity was 1.53 (20
150 ° C.) and a specific gravity of 1.28
230 ml of a second diluted sulfuric acid (20 ° C.) was mixed and injected into the battery case, and the frequency was 5 Hz, the amplitude was 50 mm, and the time was 1 hour.
By giving a vibration of 0 second, a lead storage battery having an electrolytic solution having a specific gravity of 1.28 (20 ° C.) was finally obtained. The sulfuric acid concentration of this electrolyte satisfies the standard value of the 55D23R type lead storage battery.

入したが、第1の希硫酸の排出量は特に限定されない。In this embodiment, a 55D23R type lead storage battery has been described. However, other types and types of lead storage batteries may be used if the appropriate concentrations and amounts of the second and third diluted sulfuric acids are known in advance. The invention can be applied. The effect of the present invention can be obtained even if the third diluted sulfuric acid is water instead of diluted sulfuric acid. However, when two types of liquids are mixed by means such as vibration, if one of them is water, mixing is considered to be difficult. Further, the mixing operation as in this example is not always necessary for the present invention. The reason is that when the second and third dilute sulfuric acid concentrations are very close to each other, it is considered that the electrolyte is sufficiently stirred during use of the lead-acid battery and does not adversely affect battery performance. Further, in this example, one kind of each of the second and third diluted sulfuric acids is prepared, but more than two kinds may be used. However, the use of one kind of the second and third diluted sulfuric acids as in this example can save space for manufacturing lead-acid batteries and can save the trouble of adjusting a large number of different concentrations of diluted sulfuric acid. Needless to say, it is the most preferable. In this example, the first dilute sulfuric acid was discharged at 55%, and then the second and third dilute sulfuric acids were injected into the battery case. However, the discharge amount of the first dilute sulfuric acid is not particularly limited.
