(Discharge Rate) The discharge power of a battery is the amount of power that the battery can deliver over a certain period of time. The discharge power rating is usually expressed in amperes (A) or watts (W). The higher the discharge rate, the more power the battery can deliver. Batteries are one of the most important inventions of our 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.
The charge and discharge current of a battery is measured in C-rate. Most of portable batteries are rated at 1C. This means that a 1000mAh battery would provide 1000mA for one hour if discharged at 1C rate. The same battery discharged at 0.5C would provide 500mA for two hours.
This occurs since, particularly for lead acid batteries, extracting the full battery capacity from the battery dramatically reduced battery lifetime. The depth of discharge (DOD) is the fraction of battery capacity that can be used from the battery and will be specified by the manufacturer.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
The battery voltage at discharge is the amount of voltage that is present in the battery when it is not being used. This can be affected by many factors, such as the type of battery, the age of the battery, and how much charge is left in the battery. The average battery voltage at discharge is around 12 volts.

How To Calculate Battery Discharge Rate
You can use Peukert''s law to determine the discharge rate of a battery. Peukert''s Law is (t=Hbigg(frac{C}{IH}bigg)^k) in which H is the rated discharge time in hours, C is the rated capacity of the discharge rate in amp-hours (also called the AH amp-hour rating), I is the discharge current in amps, k is the Peukert constant without dimensions and t is the actual …

In electricity, the discharge rate is usually expressed in the following 2 ways. (1) Time rate: It is the discharge rate expressed in terms of discharge time, i.e. the time experienced by a certain current discharge to the specified termination voltage ch as C/5, C/10, C/20 (2) C rate: the ratio of the battery discharge current relative to the rated capacity, that is, times the rate.

How to Calculate the time of Charging and Discharging of battery?
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
