Although the discharge test is a true test of the battery and provides valuable information, people are generally reluctant to do discharge testing, primarily because it is labor-intensive and time-consuming. It is also one of those tests that needs to be done right the first time on that day.
The battery discharge test is perhaps one of the most reliable tests you can perform on a battery or a battery bank. It provides a comprehensive insight into the health status of the cells. In this post, we will analyze this test applied to stationary battery technology, with a focus on battery banks. Let’s get started!
If a mistake is made while starting the test, the test cannot be restarted immediately because the battery discharge data can be affected by the previous attempt. Proper planning and preparation will ensure that there are no hiccups and a discharge test can be carried out in the right manner and with ease.
A discharge test carried out immediately after installation or commissioning of the string is called an acceptance test. For lead acid batteries, the measured percent capacity must be at least 90% of the rated capacity for the battery to pass the test. The results obtained from this test can be used as the baseline for future measurements.
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.
This test can be performed on all types of batteries. However, you must consider and be aware of the technical specifications of each battery bank. Such as cut-off voltage, maximum discharge current, temperature, among others. For instance, the working temperature for a sealed battery bank is much lower than for ventilated ones.
