There are several methods and devices that can be used to test a battery's capacity. The easiest and most common way to test a battery’s capacity is to measure its voltage and current under load. Once the battery is fully charged first, a load is placed on the battery and then the voltage and current of the battery is measured.
Step-by-Step Multimeter Testing: Charge the Battery Fully: Ensure the battery is fully charged. Set Up the Multimeter: Configure the multimeter to measure current and voltage. Measure Voltage: Connect the multimeter to the battery terminals to measure the voltage. Measure Current: Measure the current the battery provides to a device.
Measure the current: Use a data acquisition system or a microcontroller with an analog-to-digital converter (ADC) to measure the current flowing in and out of the battery. Integrate the current over time: Integrate the measured current over time to obtain the total charge transfer (in Coulombs).
To estimate battery capacity using a multimeter, follow these steps: Measure the OCV using the multimeter’s voltage setting. Compare the measured voltage with the manufacturer’s voltage vs. state of charge (SOC) chart. Estimate the battery capacity by multiplying the rated capacity by the SOC percentage obtained from the chart.
Allow the battery to rest: Before measuring the OCV, let the battery rest for a specified period (typically 1-2 hours) to minimize the effects of voltage fluctuations due to load changes. Measure the open-circuit voltage: Use a digital multimeter or another accurate voltage measurement device to measure the battery’s OCV.
The capacity of any battery is the total area under that curve, the area under the curve is integral, so if you know how to do your integrals and you’ve got the actual data, you can do an integral of it, but we would not do that. The other easier way to do it is to log the voltage and the current from the battery for a given load.
