Open Circuit Voltage (OCV):

Equilibrium potential 3.0 V to 4.2 V on average, dependent on temperature, storage duration and state of charge.
Nominal Voltage is typically 3.7 V, see specifications for individual batteries. 

End of Discharge Voltage:

The capacity C of the lithium ion battery is defined by the discharge current I and the discharge time t: C = I * t
I = constant discharge current
t = duration from the start of discharge to end of the discharge
Rated capacity: The rated capacity C represents the energy delivered by the battery at a discharge rate of 5 h (0.2 CA) expressed in mAh (milliampere-hours). The reference temperature is + 22 °C ± 3 °C, and the final discharge voltage is 3.0 V.

Available Capacity:

The factors that affect the available capacity are:

• Discharge rate
• End of discharge voltage
• Ambient temperature
• State of charge
• Cycle history

At the higher than nominal discharge rates, the available capacity is accordingly reduced.
