Why
The battery is also called battery. In addition to starting the engine, it can also supply power to the electrical equipment when the engine is not working. At the same time, it also has the function of voltage stabilizing and protecting the electrical equipment. It can be said that the battery is a very important power supply device on the vehicle of white powder.
The white oxide is mainly composed of lead sulfate and the Yellow oxide is mainly ferric sulfate. The conductivity of these two oxides is very poor. If they are in the contact position of wires, they will form a large contact resistance and reduce the output current of the battery. Serious will also affect battery charging. These oxides are soluble in water, so they can be washed off with boiling water of white powder.
