"XH-M239 18650 Lithium Battery Capacity Tester Module MaH/mwH Digital Battery Measurement Tools Name: 18650 Lithium Battery Capacity Tester Model: XH-M239 Display accuracy: 0.1 Measurement accuracy: 1mAH Power supply voltage: DC5-12V/18650 battery Standby current: 5mA Discharge current: about 500mA Load power: 10W 8Ω Appearance size: 111*97*25mm Installation size: (as shown on the right) φ3mm Weight: 93g 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 (3.24 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. Measurement time calculation 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."
