1, charging mode
This charger is suitable for 14500/14650/16340/16650/17650/17670/18350/18490/18500/18650/18700/22650
/20700/21700/22700/25500/26650/26700 specifications of lithium battery.
2, circuit anti-reverse function
When the charger is in the charging or standby state, if the positive and negative terminals of each channel are short-circuited, cross-short, the battery itself is short-circuited, and the positive and negative terminals of the battery are reversed, the product protection function is activated, and the charger will not be damaged.
3, low voltage activation function
When the charger is in standby, the low voltage battery (battery voltage ≤ 2.9V) is correctly connected to the charging channel,and the trickle charge function of the charger is activated to automatically activate the low voltage battery.
Due to factors such as the number of times of over-discharge of the low-voltage battery, capacity, degree of over-discharge, and duration of low-voltage, the activation time varies greatly. After the battery is activated, charge it according to the charging process.
4, overcharge protection and automatic detection of charging function
Connect the battery to be charged. If the battery voltage is <4.10V, the charger starts the charging function and charges the rechargeable battery. When the battery is full, the charger activates the overcharge protection function and automatically stops charging.
If the battery is not removed after a long period of time, the charger will consume a certain amount of battery power. When the battery voltage is lower than 4.10V, the charger restarts the charging function.
