Explanation of lithium battery labeling parameters.cr2032 3v lithium battery

  1、 Single cell lithium battery voltage: 3.7V or 4.2V. The labeling may vary from different manufacturers, but the essence is the same. 3.7V refers to the typical value during stable discharge, and 4.2V refers to the voltage at full charge.

  2、 Capacity: 2200mAh. Battery capacity refers to the ability of a battery to store charges, that is, mAh is the unit of measurement for battery capacity, not the unit of measurement for electrical energy. The movement of charges generates current and does work, which is called electrical energy, also known as electrical work. The unit of description for electrical work is commonly known as "degree", which is (kilowatt hour). 1 degree=1000, the international unit is "watt hour", which is one thousandth of a degree. Electric power represents the rate of energy consumption, with P=U * I and P=1kW. An electrical appliance consumes 1 kilowatt hour of electricity per hour, which is one kilowatt hour of electricity.

  But what is the relationship between 2200mAh and these? 2200mAh indicates that the battery can be discharged for one hour with a voltage of 3.7V and a current of 2200mA.

  MAh is the unit of measurement for battery capacity, which is actually the total number of electrons stored inside the battery that can be used externally. 1C (Coulomb) is approximately equivalent to the amount of electricity of 6.25 x 10 ^ 18 electrons, which is C/Coulomb, the international unit.
