The minimum discharge stop voltage of 18650 battery is 2.75V. In general, when the voltage is reduced to 0.875 times of the rated voltage (3.24V), it should be charged, and if it continues to be used, the voltage will drop rapidly, and it may be damaged by overdischarge, which will affect the life span. (recommended discharge termination voltage 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 detector is about 500mAH. the measuring time is about 4 hours.
