Lithium ion battery charger is the most common battery charger in our life. Some people even call it "button battery charger" according to its compact appearance as lithium ion battery. At present, there are still many mistakes about the charging method of lithium ion battery charger. Today, I will introduce the advantages and disadvantages of lithium ion battery charger and whether ordinary chargers can charge lithium ion batteries.

Lithium ion battery chargers are specially used to charge lithium ion batteries. Lithium ion batteries have high requirements on chargers and need to protect circuits. Therefore, lithium ion battery chargers usually have high control precision and can charge lithium ion batteries at constant current and voltage. Lithium ion battery charger has protection functions such as short circuit, reverse battery polarity, over-current and over-voltage. When the power supply voltage is low, it is in low power consumption sleep mode, and the battery leakage current is very small;

Advantages: high working voltage, small size, light weight, high energy, long life, safe and fast charging, wide allowable temperature range, small discharge current, no memory effect, no environmental pollution.

Disadvantages: It has no interchangeability with dry battery, cannot be charged quickly, has high internal impedance, large variation of working voltage, large discharge rate, fast capacity decline, and cannot be discharged with large current.
