There are two indicator lights on the charger, the green light is on when the charger is connected to the power supply, the charger light is red when charging and green when fully charged
The state of shipment is basically fully charged, so the first charge is displayed for a very short time to become a green light.
When no battery pack is connected, the green light shown at this time is the power indicator, which means that the charger is powered on.
Compatible with BATOCA type A lithium-ion battery.
