Battery Capacity
Since the capacity of a battery does not have a unique value, the manufacturers write an approximate value on their products. The approximate value is called Nominal Capacity and does not mean that it is the exact capacity of the cell. Fig. 2.2 shows a typical lithium battery used for cell phones. As it is indicated on the cover of the cell, it has Q n = 3500 …
Relation between battery cell capacity & internal resistance
Is more correct to say that internal resistance is related to battery discharge current. Indeed, a battery with higher discharge current will have a smaller internal resistance. For example, a LiPo prismatic cell of 3000mAh used to have a bigger discharge current than a cylindrical LiIon with the same capacity.

BU-904: How to Measure Capacity
SAE specifies the capacity of a starter battery by reserve capacity (RC). RC reflects the runtime in minutes at a steady discharge of 25A. DIN and IEC assess the battery in Ah and measure the runtime at a typical discharge rate of C/20 (5h rate) for starter batteries. A 60Ah would discharge at 12A.
Battery Capacity
If the battery is being discharged very quickly (i.e., the discharge current is high), then the amount of energy that can be extracted from the battery is reduced and the battery capacity is lower.
