A battery’s capacity can be estimated relatively accurately using a set of measurements and some complex math, but the most simple way to measure a battery’s capacity is to measure the power going into or out of the cell. Power going into the cell would be charge testing and power coming out of the cell would be considered discharge testing.
This post demonstrates the procedure to test the capacity of a battery. The test will determine and compare the battery’s real capacity to its rated capacity. 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.
Accurate measurement of battery charge and capacity is essential for ensuring reliability, longevity, and efficiency. Mismanagement of batteries can lead to shortened lifespans, unexpected downtimes, and higher operational costs.
Multimeters are versatile tools that measure several electrical properties, including voltage, current, and resistance. When measuring battery capacity, a multimeter can help check the voltage and current output. While it’s useful for general diagnostics, it won’t provide an exact figure for capacity.
