We understand that lithium-ion batteries are not like nickel-chromium batteries, and now we often see that the lithium-ion batteries are often seen, and 18650 is also a kind of lithium-ion battery. After a long time, it will not be able to fill in the battery. Electrically, this is due to overhang, that is, the battery's voltage has been lower than the cutoff voltage of the battery discharge, and is generally about 2.

5V about the general lithium ion battery. How to deal with the battery for a long time without or the discharge voltage has reached a low battery, can you still be activated? Speaking of activation, a lot of lithium-ion batteries will not be a monomer, but in the form of a battery pack, then there will be a charging management board, and the important part is charging management IC. This IC has overchard, overchart , Overcurrent, short-circuit, etc.

So sometimes you can use the activation method to try it. Lithium-ion battery charging is generally used in a constant current-constant voltage, that is. Therefore, it can be charged with a DC power supply for a period of time.

When it arrives until the cutoff voltage is used to charge the original charger, although this method is time, it is not possible, after all, the battery has affected the performance of the battery, but There are also phenomena that have been activated for several years. So how do you maintain lithium-ion batteries? 1 Due to the self-discharge phenomenon of lithium ion batteries, if the battery is not used, the battery voltage cannot be less than its cutoff voltage, preferably from 3.8 to 4.

0V; 2 suggest that the lithium-ion battery is charged for half a year, It is the battery over the cutoff voltage; 3 battery storage ambient temperature and humidity should be appropriate, to operate according to specifications; Group charging. .
