What is the capacity of the battery?

The capacity of the battery is divided into the rated capacity and the actual capacity. The rated capacity of the battery refers to the stipulation or guarantee that the battery should discharge the minimum amount of electricity under certain discharge conditions when designing and manufacturing the battery. The IEC standard stipulates that nickel-cadmium and nickel-metal hydride batteries are charged at 0.1C for 16 hours and discharged at 0.2C to 1.0V at a temperature of 20°C ± 5°C. The battery's rated capacity is expressed as C5. For lithium-ion batteries, it is stipulated to charge for 3 hours under normal temperature and constant current (1C)-constant voltage (4.2V) controlled charging conditions, and then discharge at 0.2C to 2.75V. The discharged electricity is its rated capacity. The actual capacity of the battery refers to the actual power released by the battery under certain discharge conditions, which is mainly affected by the discharge rate and temperature (so strictly speaking, the battery capacity should specify the charge and discharge conditions). The unit of battery capacity is Ah, mAh (1Ahu003d1000mAh). Disclaimer: Some pictures and content of articles published on this site are from the Internet.
