Using the battery''s operating voltage as the ordinate, discharge time, capacity, state of charge (SOC), or depth of discharge (DOD) as the abscissa, the curve drawn is called the lithium battery discharge curve. The most basic forms of discharge curves are voltage-time and current-time curves.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
Connect the probes: Place the red probe on the positive terminal and the black probe on the negative terminal. Read the voltage displayed on the screen. Interpreting the Voltage: A fully charged lithium battery (3.7V) should read between 4.1 and 4.2 volts when fully charged.
When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.
The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages
One of the simplest and most effective ways to gauge a lithium battery’s health is by measuring its voltage. Voltage essentially tells you how “full” the battery is at that moment. Steps to Check Voltage: Set your multimeter to DC voltage mode. Look for a “V” symbol with a straight line on your multimeter’s dial.
The charging conditions of the battery: charging rate, temperature, cut-off voltage affect the capacity of the battery, thus determining the discharge capacity. Method of determination of battery capacity: Different industries have different test standards according to the working conditions.

When the battery reaches its full charge cut-off voltage, constant voltage mode takes over, and there is a drop in the charging current. The charging current keeps coming down until it reaches below 0.05C. The battery reaches full charge voltage some time after the CV mode starts (as soon as one of the cells reaches its full charge voltage).
Lithium-ion cells can charge between 0°C and 60°C and can discharge between -20°C and 60°C. A standard operating temperature of 25±2°C during charge and discharge allows for the performance of the cell as per its datasheet.. Cells discharging at a temperature lower than 25°C deliver lower voltage and lower capacity resulting in lower energy delivered.
