Problems solved by technology

[0002] At present, in the process of manufacturing lead-acid batteries, the process of internalizing the battery is required. In order to prevent insufficient acid solution, the current method of internalizing the battery uses rich liquid formation, that is, full acid formation, that is, the existing acid adding pot There are openings on the upper and lower sides. When in use, it is always set on the acid charging hole of the battery. It cannot be separated from the battery, so it cannot be sealed and stored independently. During the production process, it is impossible to accurately obtain the required battery capacity through quantitative acid addition, let alone Flexible production according to the required battery capacity

Abstract

The invention relates to a manufacturing method of a storage battery, and the method comprises the following steps: 1, adding a first density sulfuric acid solution with the density of 1.04 g / cm<3>-1.28 g / cm<3> into a lead-acid storage battery; 2, performing electrifying for formation; 3, adding a second density sulfuric acid solution into the battery through an acid adding kettle, wherein the density of the second density sulfuric acid solution is 1.25-1.6 g / cm<3>, the density of the second density sulfuric acid solution is greater than the density of the first density sulfuric acid solution,and the acid adding kettle is an acid adding kettle capable of storing quantitative acid liquid. According to the manufacturing method of the storage battery, the capacity of the lead-acid storage battery can be accurately obtained, and flexible production is achieved.
