The Zinc Cylinder is used as the container and used as the negative electrode material of the battery at the same time. The manganese dioxide is the positive electrode, and the zinc chloride solution is the main component of the electrolyte, which is absorbed in the paste layer of the traditional carbon dry battery. This increases the amount of manganese dioxide used in the positive electrode, reduces the internal resistance of the battery, and improves the continuous discharge performance under a larger load. It is commonly known as high power battery (high power battery, after the battery model is marked with P). The battery does not contain mercury or heavy metals such as cadmium. The battery capacity of the same volume is 1-3 times higher than that of the normal carbon battery, making it a more cost-effective product. The electronic scales are mainly with AAA, AA or CR2032 batteries.
