Is it worth recycling those 18650 lithium batteries you've been storing? In this video, we perform the ultimate test: a nearly 4-hour full discharge test to measure the real capacity (mAh) of two used cells connected in parallel. We use the popular ZB2L3 module to subject the batteries to a controlled discharge down to the safety voltage. Find out the final capacity obtained, how the discharge curve behaves, and if your old batteries have enough life left to be recycled in projects. KEY EXPERIMENTAL RESULTS: Total Capacity Obtained (2 cells): 4490 mAh Actual Capacity per Cell: 2245 mAh (Excellent performance for used batteries!) Average Discharge Current: 1.105 Amps Programmed Cut-Off Voltage: 3.0V 00:00 Introduction: The end of old batteries and the era of 18650 Lithium. 01:50 Equipment: ZB2L3 module, used cells, and multimeters. 03:20 Setup: Connecting cells and load resistors. 04:45 Start of Test: Constant Current (CC) phase and data logging. 07:10 Discharge Curve: Analyzing how the voltage behaves during the test. 09:30 Current: Explanation of the 1.1A in the discharge circuit. 11:05 The Final Result! The ZB2L3 cuts in and reveals the Total Capacity. 12:30 Conclusion: Analysis of 2245 mAh per cell and feasibility for recycling.
