[0002] Lead-acid batteries are mainly composed of positive plates, negative plates, electrolytes, separators and tank covers, among which the electrolyte is sulfuric acid solution; in the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main components of the positive and negative electrodes are both lead sulfate. During the production process of lead-acid batteries, a certain amount of sulfuric acid solution needs to be added according to the technical requirements of battery production. Among them, the accuracy of the amount of acid injected into the battery will affect the performance and consistency of the battery; in the acid addition process, the gas inside the battery shell is usually extracted first and a low vacuum is reached, and then the acid is poured into the battery shell. Under the action of the external atmospheric pressure, the acid quickly and evenly enters the battery shell.

[0003] However, in the actual production process, due to the lack of accuracy in controlling the amount of acid added, it is easy to have too much or too little acid. If too much sulfuric acid solution is added, it is easy to cause the sulfuric acid solution to overflow and cause corrosion and other problems. If too little sulfuric acid solution is added, it is easy to cause insufficient sulfuric acid solution and affect the storage performance of the battery. At the same time, due to the lack of accuracy in controlling the amount of acid added, the consistency between each battery is poor, especially reducing the life of the entire group of batteries after grouping.
