2. Description of keys and functions
u The charger has a button that selects the charging current. The current button is easy to use. In any case, hold down the selection key and hold it for 500 seconds to convert 1000mA charging current. Press the selection key lightly to change the rechargeable battery. When a battery is selected for charging (eg 3V 3.85V), it enters the charging state for 5 seconds.
u When the charger is connected to the 5V power supply, all the LEDs of the charger are all on instantly. If the battery is not in the charging operation, 500mA (LED) is displayed, and the LED indicator of the bad battery flashes.
u When the charger is connected to the battery, it automatically recognizes 3.7V lithium (Li-ion) and 1.2V Ni-MH.
u Iron phosphate 3.0V (Liepo4) and lithium battery 3.85V (Li-ion) need to be manually selected. When charging is selected, it will enter the charging state within 5 seconds. When the system is charged by default, tap the select key to query the battery type and cannot change other functions
