What is the reason why the battery cannot be charged? How is it diagnosed?
Battery charging means that the battery charging time is long, and the voltage rises slowly during normal operation. The reasons are as follows:
1. In the charging circuit The terminal is loose or rusty, which increases the resistance and reduces the current intensity.
2. The battery plate is vulcanized, and a layer of white aluminum sulfate grains with poor conductivity is attached to the surface of the battery plate. When the coarse crystal grains are blocked by the plate holes, the electrolyte is not easy to penetrate, the internal resistance increases, and the current cannot pass through.
3. Charging or discharging the colloidal storage battery by taking a large current will damage the battery panel. If the specific gravity of the electrolyte is too large or the liquid level is not enough, the battery panel is damaged. When making a diagnosis, check whether the connector is loose or corroded, and judge whether the board is vulcanized according to the charging phenomenon. If the temperature of the electrolyte increases rapidly or the charging time is not long, the electrolyte will produce a large number of bubbles, but the voltage has not been improved, and the specific gravity of the electrolyte has not increased significantly, so that the electrode plates will be vulcanized. When the vulcanization is not serious, you can pour out the entire electrolyte, pour in distilled water, and then charge it for a long time with a small current of about 2 amperes to dissolve the aluminum sulfate, but the battery temperature is not allowed to rise. When the specific gravity of the electrolyte does not increase within a few hours, the battery is fully charged and discharged.
After many charge and discharge cycles, the active material should be replaced. If it is still abnormal, the new product should be replaced. Contact: 18038832979
