★ About 18650 battery:
The minimum discharge stop voltage of 18650 battery is generally 2.75V. Under normal circumstances, when the voltage drops to 0.875 times the rated voltage (3.24V), it should be charged. If you continue to use it, the voltage will drop rapidly, and it may be damaged by over-discharge, which will affect the life. (It is recommended to set discharge stop voltage to 3.5V). The charging voltage is generally 4.20V-4.3V/4.35V.
★ Measurement time calculation:
Assuming that battery capacity is 2000mAH, the discharge current of the tester is about 500mAH (2000+500=4), and the measurement time is about 4 hours.
