A Lithium Ion battery's published rated capacity is the capacity of the cell when the load current is one fifth of the rated capacity (the C Rate). When the current varies from C/5, the capacity will change due to chemical reaction rates including a chemical effect called concentration polarization.
The capacity of lithium-ion batteries can be reduced by as much as 25% at high current (C rating) and operating temperature as compared to their published capacity. Manufacturers typically publish the the capacity when the load is C/5 or one fifth of the rated capacity.
