How to buy a lithium battery charger?

　　First of all, you must first know which type of battery you use or in lithium batteries, and the second is to check the working voltage of the battery. According to the instructions of the battery label, you can buy a suitable charger.

　　It should be noted that the charging process of lithium -ion batteries is completely different from the charging process of nickel -cadmium and nickel -metalized batteries. It is a complex electrochemical response process. Therefore, a dedicated charger needs to be configured for charging. Even if the dedicated lithium battery charger is very strict due to the requirements for the charging voltage difference (generally 1%), whether the voltage when the battery is fully charged is 4.1V or 4.2V.

　　The quality of the charger plays a vital role in the life of lithium batteries. When the charging voltage or charging current is too large, the lithium -ion battery will even be scrapped. Therefore, people often say that a battery sometimes does not use bad, but bad. At the same time, the sustainable development of electronic technology and switching power technology has changed the design ideas of traditional linear power supply. Therefore, the research of lithium -ion battery charger improves its reliability and operating efficiency, ensure the safety of batteries, and extend the life of the battery. It has important practical engineering significance.
