The State of Charge (SoC) of a battery cell is required to maintain it''s safe operation and lifetime during charge, discharge and storage. However, SoC cannot be measured directly and is estimated from other measurements and known parameters. This leads to errors in the estimated SoC and that means it is not possible to fully exploit the full capability of the cell.

Connect the battery to a discharge resistor and measure the voltage over time. A healthy battery should maintain a stable voltage throughout the test. Measuring the internal resistance provides insight into the battery’s overall health. Connect the battery to a multimeter capable of measuring resistance and obtain the internal resistance reading.
Locate the positive and negative terminals on your battery. For an exact measurement of a battery’s charge, use a voltmeter. Start by finding the positive and negative terminals on the battery you’re measuring. These are marked on the battery.
A battery’s SOC is often measured by its voltage, as the process is simple and yields fairly accurate results. It basically converts a reading of the battery voltage to SOC and displays it to the user. Let’s try to understand this process with the help of an analogy. A battery is like a tank of water with a faucet at its base.
Short answer: Accurately determining the amount of charge left in a battery is no easy task, but there are a few methods that can be used, including estimation based on voltage, estimation based on current (Coulomb Counting), and estimation from internal impedance measurements.
Measure the time it takes for the battery to discharge completely. If the battery runs out of power quickly or fails to reach its rated capacity, it may need replacement. A discharge test determines the battery’s ability to sustain a steady output under load. Connect the battery to a discharge resistor and measure the voltage over time.
