All devices get "leftover" battery charge percentage by simply measuring the voltage. The thing is that batteries when fully charged have a higher voltage and when fully discharged - lower. For example a 12v battery: charged - more than 12.6V, fully discharged 11.6V - 11.8V. A 3.7V battery: (fully) charged - 4.2V, fully discharged - 2.6V - 2.8V.

If you have a device that uses a coin battery, check the manufacturer''s website to see how long 350 mAH the battery is expected to last. You may also want to keep a spare battery on hand so you can replace it when necessary. A 3V lithium battery can last anywhere from 2 to 10 years, depending on the brand, type, and size. Factors such as
Gather the Necessary Tools for Testing a Lithium Battery . To test a lithium battery with a multimeter, you will need the following: A multimeter; A pair of safety glasses ; Gloves (optional) Insulated pliers or screwdrivers ; Crocodile clips ; Step by Step Guide on How to test lithium battery with multimeter Prepare the Battery for Testing
The voltage test is among the most critical tests to conduct when testing a lithium-ion battery with a multimeter. The battery''s voltage level, which can be used to determine whether it is completely charged or not, will be determined by this test.
The ideal voltage for a lithium-ion battery depends on its state of charge and specific chemistry. For a typical lithium-ion cell, the ideal voltage when fully charged is about 4.2V. During use, the ideal operating voltage is usually between 3.6V and 3.7V. What voltage is 50% for a lithium battery? For a standard lithium-ion cell, 50% charge is
3.IEC Standard Cycle Life Test:. IEC stipulates that the standard cycle life test of lithium batteries is: Step 1: Discharge the cell to 3.0V with the discharge rate at 0.2C and then charge to 4.2V with charging rate at 1C and constant current and constant voltage. The experiment requires that the cut-off current is 20mA.
To perform a load test, follow these steps: Connect the multimeter''s positive probe to the battery''s positive terminal and the negative probe to the negative terminal. Set the multimeter to the DC voltage setting. Turn on any devices that draw power from the battery. Take note of the voltage reading on the multimeter.
