The lithium battery charger is a charger designed to charge lithium-ion batteries. Lithium-ion batteries have higher requirements on chargers and require protection circuits. Therefore, lithium battery chargers usually have high control precision and can perform constant current and constant voltage charging on lithium-ion batteries.

[Charging process]

When the power is not connected, the LED on the board is not lit.

The power supply is connected to the circuit board, and the green LED is continuously lit. At this time, the circuit board waits for the lithium battery to be placed.

After the lithium battery is put in, it starts to charge and the LED turns orange.

When the lithium battery reaches the full condition, the charging stops and the LED turns orange.

After the lithium battery is fully charged, the battery is removed, the LED turns green, and the lithium battery is recharged.

The charging percentage is displayed during charging

LED lights:

Continuous green: waiting for the battery to be placed

Continuous yellow: charging

Continuous orange: The battery is fully charged or charged for 6 hours

Flashing orange: warning message (output short circuit, reverse polarity, abnormal temperature)
