[0002] The valve-regulated AGM lead-acid battery has a small gap between the plates due to its tight assembly process requirements. During the production process, the acid adding process needs to be done with a vacuum acid adding machine. First, the acid adding machine will extract the air inside the battery to create a negative pressure state inside the battery, making it easier for the acid to quickly enter the plates and separators inside the battery.

[0003] The patent document with the publication number CN215377644U discloses an acid adding pot, comprising: a shell, at least one acid adding chamber is arranged in the shell, a top cover is arranged on the top of each acid adding chamber, an acid adding nozzle is arranged on the bottom of each acid adding chamber, an acid adding hole for accommodating an acid filter sheet is arranged on the top cover, and a placing boss for placing the acid filter sheet is arranged on the acid adding hole. By arranging an acid adding hole for accommodating an acid filter sheet with a ventilating function on the top cover, and inserting an acid adding tube in the acid filter sheet, the purpose of filling the lead-acid battery with acid solution under a vacuum environment can be achieved, which greatly shortens the filling cycle.

If there is a difference between the vacuum value at the battery end and the value on the equipment, the acid solution cannot effectively infiltrate the plate and the separator, affecting the battery performance.
