For example, a battery with a nominal capacity of 100 Ah (C 10 capacity for a 10hour discharge), when discharged with a 10 A current (C/10 rate) will take 10 hours to discharge the battery fully. However, if the same battery is discharged with double the current (20 A), due to the internal losses, the discharge time would not be the expected 5 hours, but a shorter time.

The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
By calculating the discharge rate, you can choose the appropriate discharge rate for your specific application and ensure the safety of the battery. To calculate the discharge rate of a lithium-ion battery, you need to know two values: the battery's capacity in ampere-hours (Ah) and the discharge current in amperes (A).
The charge and discharge current of the battery is measured in C-rate. The majority of portable batteries are with a rating of 1C. Which means that a 1000mAh battery provides 1000mA for just one hour if discharged at 1C rate. Exactly the same battery discharged at . 5C provides 500mA for 2 hrs.
Charge Rate (C‐rate) is the rate of charge or discharge of a battery relative to its rated capacity. For example, a 1C rate will fully charge or discharge a battery in 1 hour. At a discharge rate of 0.5C, a battery will be fully discharged in 2 hours.
Battery capacity: The discharge rate can also affect the battery's capacity. The higher the discharge rate, the lower the effective capacity of the battery. By calculating the discharge rate, you can determine the effective capacity of the battery for your specific application and choose the appropriate battery capacity.
