1C, 2C, 0.2C in battery discharge means: 1, C represents the capacity of the battery itself, the unit is AH\/MAH;
2, C: used to indicate the ratio of the battery charge and discharge current size, that is, the multiplier. That is, the battery is 1000MAH, and the 1C discharge is 1000MAH discharge. Generally, the size of the charge and discharge current is commonly expressed by the charge and discharge ratio, that is, the charge and discharge ratio = charge and discharge current\/rated capacity; For example, when a battery with a rated capacity of 100Ah is discharged with 20A, its discharge rate is 0.2C. Battery discharge C rate, 1C,2C,0.2C is the battery discharge rate: a measure of how fast or slow the discharge is. Introduction to battery discharge efficiency: discharge rate is referred to as discharge rate, commonly used time rate and rate. 1, the time rate is the discharge rate expressed by the discharge time, that is, the time experienced by a certain current to the specified termination voltage, such as a battery rated capacity is 20 hours rate of 12AH, that is, C20=12AH, then the battery should be discharged with 12\/20=0.6A current, continuous 20H is qualified. 2, the ratio refers to the value of the battery discharge current is a multiple of the rated value, such as the discharge current is expressed as 0.1C20, for a 12AH (C20) battery, that is, the current discharge of (12\/20) *0.1=0.06A, 3C 20 refers to the current discharge of 1.8, the lower label of C indicates the discharge rate.
Used to indicate the size of the discharge current, C is used to indicate the capacity, such as 2000mah battery, discharge current 1C is 2a, 2C is 4a, 0.2C is 400ma.
