VOLTAGE DEFINITIONS OF LITHIUM ION BATTERY LP18650

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 voltage at the end of discharging is 2.75 V to 3.2 V per cell, depending on discharge rate and temperature.
End of Charge Voltage: Terminal voltage after charge is 4.2 V.

CAPACITY DEFINITIONS OF LITHIUM ION BATTERY 18650

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.

CURRENT DEFINITIONS OF LITHIUM ION BATTERY 18650

Charge and discharge rates of Cylindrical lithium ion battery may be given as multiples of the Rated Capacity (C) in Ampères (A) with the term CA.
Example:

Rated Capacity C = 1000 mAh
0.1 CA = 100 mA, 1 CA = 1000 mA

Nominal Discharge Current:

The nominal discharge current of a CellPac LITE battery is the 5 hour discharge current (0.2 CA). It is the current at which the nominal capacity of a cell is discharged in 5 hours.

I = C/t = C/5 = 0.2 CA when t = 5 h
