After the Mirco is connected to the power, the indicator light is on, and the fourth light stops flashing; when the battery is inserted, the power grid shows the charging progress. 4 lights are on and stop flashing, indicating that the battery is fully charged.4. The key is to detect the battery power, and the LED indicates the corresponding power percentage.5.With 0 V voltage activation function.6.Charging mode: TC / CC / CV three-stage battery mode.TC: less than 2.9V, low current 0.1A chargingCC: constant charge 2A chargeCV: constant voltage 4.2V to cut-off current 0.15A7. Insert the 18650 lithium battery, connect the power supply, and the charger will automatically start charging the battery. When one battery is inserted (any slot), the charging current is 2A, and when two batteries are inserted, the charging current is 1A per slot. When the two charged batteries are inconsistent, the low-charge battery will be prioritized and recharged at the same time. To avoid overcharge and over discharge.8. This charger supports charging while discharging, giving priority to charging external devices. When the external device is charged, it is directly powered by the power supply, which can reduce the number of battery cycles and prolong the battery life.9. Suitable charge: without protection board 3.6V / 3.7V Li-ion / IMR / ICR / INR 18650 battery
