What does discharge current mean. The current flowing through the circuit in the discharge process is called the discharge current. For instance, the 1C rate means the entire battery will discharge within one hour, so if a battery has 100 Amp-hrs of capacity with 1C discharge rate, it will have 100 Amps discharge current.
Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.

Depth of Discharge. In many types of batteries, the full energy stored in the battery cannot be withdrawn (in other words, the battery cannot be fully discharged) without causing serious, and often irreparable damage to the battery. The Depth of Discharge (DOD) of a battery determines the fraction of power that can be withdrawn from the battery.
At a 2C discharge, the battery exhibits far higher stress than at 1C, limiting the cycle count to about 450 before the capacity drops to half the level. Figure 6: Cycle life of Li-ion Energy Cell at varying discharge levels [4] The wear and tear of all batteries increases with higher loads. Power Cells are more robust than Energy Cells.

As a battery discharges, chemical energy stored in the bonds holding together the electrodes is converted to electrical energy in the form of current flowing through the load. Consider an example battery with a magnesium anode and a nickel oxide cathode.

Note that the highest discharge current that is mentioned is 1000 mA = 1 A. That does not mean you cannot discharge with 2 A but realize that the battery''s capacity will be less at such a high current. You will get less energy out of the battery compared to a more realistic discharge current of for example 100 mA.
Max Discharge Current (7 Min.) = 7.5 A; Max Short-Duration Discharge Current (10 Sec.) = 25.0 A; This means you should expect, at a discharge rate of 2.2 A, that the battery would have a nominal capacity (down to 9 V) between 1.13 Ah and 1.5 Ah, giving you between 15 minutes and 1 hour runtime.
