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.
In general, testing battery capacity is an important step in evaluating battery performance, and different testing methods have their own advantages and disadvantages. When choosing a test method, factors such as actual needs, equipment conditions, and test accuracy requirements should be considered comprehensively.
Before starting the acceptance capacity test, measure & record individual cell/unit float voltages. Load bank capability of delivering the required discharge current. Use digital voltmeters to check entire battery discharge voltage. Use an amp meter to check battery discharge current.
The time-adjusted technique is recommended since it is easier to calculate while remaining accurate. See the time-adjusted approach that follows: To compute % capacity using the time adjusted technique, divide actual discharge time by the rated time, then multiply by 100. This assuming the battery is at 25°C.
For professional maintenance personnel, the capacity tester is the preferred tool for measuring battery capacity. By simulating the actual charging and discharging process of the battery, the capacity tester can accurately measure the capacity information of the battery.
The ampere-hour rating is calculated by multiplying the number of amperes of current that the battery can supply by the number of hours it takes to reach a specific end point voltage. For an accurate current determined during the test, the time of the test should match the calculation.
