Among all the tests, the discharge test (also known as load test or capacity test) is the only test that can accurately measure the true capacity of a battery system and in turn determine the state of health of batteries.
This document describes how DC load banks provide solutions for efec-tively testing batteries to ensure reliable operation. It also identifies industry standards that address battery testing. Battery capacity is the measure of energy that a battery can store. Capacity testing verifies that the battery can deliver its rated power when needed.
In any case, no matter how big the load is, power is dissipated in the instrument as heat during the test. Care should be taken to direct the heat dissipation away from the batteries and/or properly ventilate the area to avoid heating the room or batteries while testing.
There are a number of different tests like: visual inspections, specific gravity, float voltage and current measurements, discharge test, individual cell condition, inter-cell resistance, and others, which are recommended in IEEE, NERC and other standards for diagnosing the condition of the battery banks.
The necessary data can only be derived from performance testing. In order to obtain this data, a UPS battery string is typically tested using a DC load bank. The type of load test will depend on the type of batteries used in the UPS. The most meaningful tests record battery current, voltage, and temperature under load conditions.
Only one pause is allowed for the duration of the test and the pause time should not be counted in the total discharge time2. Once the test is completed, determine the battery capacity. The test equipment can then be disconnected. While performing the discharge test, one should be prepared to bypass weak cells approaching polarity reversal.
