1. Step of measurement method of 18650 lithium battery capacity measurement
1. Simple method is constant to resist electricity. You need to use a multimeter and high -power resistance. First of all, you can charge, such as on the machine, on your mobile phone. Connecting the battery full load on this resistance, usually 10 ohm 5W cement resistance is discharged and discharged to the voltage below 2.75V, the total discharge time capacity = 0.37a*time is simple, but there is a certain error difference Essence
2. Formal method: Use a battery capacity detector, first charge it to 4.20V, and then put on hold for an hour of constant flow electricity. The arbitration method is 0.2 times, such as 1000mAh capacity. Time*constant current current = battery capacity This is done in accordance with the national standard 18287 lithium battery regulations. If it is nickel -metal hydride battery, the same is true, but the charging method is not constant voltage, but the discharge is to be dedicated to each method by 1.0V.
