★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, and then continue to use, the voltage will drop rapidly, there may be over-discharge and damage, affecting the life. (Recommended discharge termination

(The voltage is set to 3.5V)

The charging voltage is generally: 4.20V-4.3V/4.35V.

★Measurement time calculation

Assuming that the battery capacity is 2000mAH, the discharge current of this tester is about 500mAH, (2000:500=4), and the measurement time is about 4 hours

about.
