With the large number of lithium-ion batteries in use and the applications growing, a functional rapid-testing method is becoming a necessity. Several attempts have been tried, including measuring internal resistance, and the results have been mixed.
This application note addresses measurements with lithium ion batteries. Setup and important parameters of lithium ion batteries are explained for single batteries as well as battery stacks. Different experiments are described by means of measurements on single coin cells. Cyclic charge discharge, leakage current, and self discharge tests are
Rapid-test Methods. No single test can capture all health indicators of a battery. Many rapid-test devices look only at voltage and internal resistance. While capacity loss of a fading NiCd or NiMH may correlate with rising internal resistance, this relationship is less evident with lithium- and lead-based batteries. Advertising capacity

Here’s how to test lithium-ion battery with multimeter effectively: Set Up Your Multimeter: Set the multimeter to DC voltage mode, typically marked with a “V” and a straight line. Measure the Voltage: Connect the multimeter’s positive probe to the battery’s positive terminal and the negative probe to the negative terminal.
The internal voltage test of lithium battery is: (UL standard) The simulated battery is at an altitude of 15240m above sea level (low pressure 11.6kPa) to check whether the battery leaks or bulges.
To test self-discharge rate, follow these steps: Fully Charge the Battery: After charging, leave the battery unused and disconnected. Measure Voltage Over Time: After several days or weeks, recheck the voltage. A healthy lithium-ion battery 12V should lose only a minimal amount of charge when unused.
The performance tests of lithium batteries include voltage, internal resistance, capacity, internal voltage, self-discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance, etc. Performance test is up to 230 items. As well as overcharge, over discharge, weld-ability, corrosion resistance, etc.
