Battery discharge testing, also known as battery load testing, is a process that test battery health statement by constant current discharging of the set value by continuously the discharge current from a fully charged state and then measuring how long the battery lasts.
There are several methods: constant current discharge, constant power discharge, constant resistance discharge that can be used to perform a capacity test, but the most common method involves discharging the battery at a constant current until the voltage drops to a predetermined level.
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.
A performance test is defined as “a constant-current or constant-power capacity test made on a battery after it has been in service”2. It is the most commonly used discharge test method and it determines if the battery is performing according to the manufacturer’s specifications and/or if it is within acceptable limits.
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.
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.
