What does the C rate stand for in the battery industry?

The C rate is representative of the charge and discharge capability of the lithium-ion polymer battery. The C rate is divided into a discharge rate and a charge rate, and "C" is used to indicate the ratio of the charge and discharge current of the battery, that is the rate.


For example, a 1200 mAh battery, 0.2 C means 240 mA (0.2 mA of the 1200 mAh battery), and 1 C means 1200 mA (1 times rate of the 1200 mAh battery). Normally high discharge rate batteries can be fast-charged.
