XH-M239 18650 Lithium Battery Capacity Tester MaH/mwH Digital Battery Measurement Tools
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 (3.24 V), 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 that the discharge termination voltage is set to 3.5V) The charging voltage is generally: 4.20V-4.3V/4.35V.
Assuming that the battery capacity is 2000mAH, the discharge current of this detector is about 500mAH, (2000÷500=4), and the measurement time is about 4 hours.
