It will take 2-3 hours to test (time is depending upon the batteries ) After 3 hours of test i got 1246mAh of capacity left in my old 18650 battery Happy to see that Thank you for visiting my Instructables Lithium Battery Capacity Tester : Hey! everyone My name is Steve . Today i'm going to show you How to Test Lithium Battery Capacity .
Test the capacity of a battery that has a voltage between 1.2 volts and 12 volts. Use the bigger tester below if testing more than 5ah. With this tester, you can check the capacity, voltage, and current of a lithium-ion battery cell.
There are several practical methods to determine the capacity of a lithium battery: Manufacturer’s Label: The easiest way is to check the battery label. Most manufacturers print the capacity in mAh or Ah directly on the battery. User Manual: The device’s user manual often specifies the recommended battery capacity.
Capacity tests are typically done with a discharge rate of 0.1C (100mA), which is about the same as a cell phone’s standby current draw. The other common test for lithium batteries is called an impedance test. This measures the internal resistance of the battery, which increases as the battery ages and wears out.
There are several methods and devices that can be used to test a battery's capacity. The easiest and most common way to test a battery’s capacity is to measure its voltage and current under load. Once the battery is fully charged first, a load is placed on the battery and then the voltage and current of the battery is measured.
In fact, there are a lot of lithium-ion cell chargers that include capacity measurement as a feature. A low-cost discharge tester can be used to test the capacity of a battery that has a voltage between 1.2 volts and 12 volts. This means that it is well suited to operate at single-cell lithium-ion voltage ranges.
