Problems solved by technology

[0002] At present, there are many problems in the process of internalization of lead-acid batteries: 1. It is difficult to ensure that the positive plate of the battery is uniformly formed, and the positive plate is prone to white spots; 2. It is difficult to fully convert the active material of the battery; 3. It is difficult to ensure that the battery distribution The charging power before the group discharge is not too much, which reduces the authenticity of the discharge data; 4. The temperature difference after the battery is overcharged leads to the distortion of the battery discharge data; 5. Leakage often occurs after the battery leaves the factory
