batteries
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.
When current flows from a battery, does voltage decrease?
However, a battery also has an effective internal resistance. This resistance is dependent on a number of things (cell chemistry, temperature, cell age). The higher the internal resistance, the more voltage will be dropped internally, and the less force the battery has to push electrons. This reference is an excellent read on the subject.

In other words, the capacity of a battery does not determine its power output; it only determines the energy it can store. To know how long a battery will last or how much power it can deliver, you need to …
Calculate the current being drawn from a battery
The higher the current being drawn from a battery, the shorter its lifespan will be. This is because high currents can cause the battery to degrade and lose its capacity over time. 5.
