What is the capacity of the battery

The capacity of the battery is divided into rated capacity and actual capacity. The rated capacity of the battery refers to the design or manufacture of the battery to specify or ensure that the battery should emit a minimum amount of electricity under certain discharge conditions. Li-ion stipulates that the battery is charged for 3 hours under normal temperature, constant current (1C) constant voltage (4.2V) controlled charging conditions. The actual capacity of the battery refers to the actual amount of electricity discharged by the battery under certain discharge conditions, mainly by the discharge rate. And the effect of temperature (so strictly speaking, the battery capacity should indicate the charge and discharge conditions). Common units of capacity are: mAh, Ah = 1000mAh).
