By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
A load bank, voltmeters, and an amp meter will be utilized to discharge the battery at a specific current till a minimum voltage is achieved. The findings will be recorded across time intervals to determine whether the battery matches the required amp-hour rating according to discharge current & duration.

Load Testing: Unlike the voltage test that measures static voltage, the load test evaluates how well a battery can maintain voltage under load. This is achieved by running a load and measuring its current while observing voltage drop.
Battery testing methods range from basic voltage to more advanced methods like diagnostic battery management (dbm), which helps detect subtle battery issues that could go unnoticed. Different battery chemistries require unique battery testing methods, such as lithium-ion (li-ion), lead-acid, and nickel-based batteries.
This provides the most accurate readings and calibrates the smart battery to correct tracking errors, but the service is time consuming and causes stress. Common test methods include time domain by activating the battery with pulses to observe ion-flow in Li-ion, and frequency domain by scanning a battery with multiple frequencies.
