The rate at which a battery is being discharged is expressed as the C rating. The C rating indicates how many hours a battery with a given capacity will last. 1C is the 1h rate and means that the discharge current will discharge the entire battery in 1 hour.

The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage. By measuring the discharge time and combining the current value, the battery capacity can be accurately calculated.
After the battery is discharged to a certain extent, the voltage is measured and the battery capacity is estimated according to the discharge curve. Although it is fast, it is recommended to use it as a preliminary screening method. 2. Constant current discharge method: a classic method for accurately measuring battery capacity
The discharge rate of a battery can be affected by a number of factors, including the load being placed on the battery, the age of the battery, and the temperature at which it is being used.
