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.
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.
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.
By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage. By measuring the discharge time and combining the current value, the battery capacity can be accurately calculated.
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.
The purpose of this test is to apply a constant current to batteries, super capacitors, or electrode materials in order to charge and discharge between defined voltage limits. This will allow you to see how a material or cells capacity, efficiency, and similar parameters are affected as a function of cycle number.

A battery test system (BTS) offers high voltage and current control accuracy to charge and discharge a battery. It is mainly used in manufacturing during production of the battery. Battery …
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 …
The capacity test can be done in various ways: constant current discharge, constant power discharge, constant resistance discharge, load profile, etc. The constant current discharge method is the most popular and is widely used. While doing the test using this method, the test current is kept constant throughout the test.
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.
During a battery discharge test (lead acid 12v 190amp) 1 battery in a string of 40 has deteriorated so much that it is hating up a lot quicker than other battery''s in the string, for example the rest of the battery''s will be …
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.

Also, 40 percent of 2008 roadside failures were battery-related, ADAC reported. Testing battery capacity keeps your systems and devices working when you need them most. Types of Discharge Tests. There are several discharge tests for battery capacity, each with its own benefits: Constant Current Discharge: This method keeps the test current ...
As shown in the table above, the current for a 10h discharge down to 1.75V per cell is 16.4 A. If the capacity did not depend on the discharge current, we would expect the test current for a 5h test to be twice as high (32.8 A). However, in this case, the C/5 test current is slightly lower at 30.9 A.
Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage. By measuring the discharge …
2. Li-Ion Cell Discharge Current. The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery''s lifespan. It''s important to match the discharge current to ...
