6 Frequently Asked Questions about “How to test the battery discharge”

What is a battery discharge test?

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.

Do you need a battery discharge test?

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.

What is a discharge test for a lead acid battery?

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.

Can a battery discharge test be restarted immediately?

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.

How to test a battery?

Pre-testing the condition of the battery is also important. It must be on float for a certain duration (3 days for lead acid batteries) prior to testing. Certain measurements can be done before starting a test. The continuity of the string can be verified by measuring impedance and strap resistance.

Can a battery pause be counted in a discharge test?

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.
