What to pay attention to when charging a lithium battery for the first time

1. Overflowing: There is no activation problem when using lithium batteries for the first time. The reason is that the charging and discharging characteristics of lithium batteries and nickel-metal hydride batteries are very different. The deeper reason is that overcharging will affect the lithium battery. In particular, liquid lithium batteries cause great damage. Therefore, charging should be carried out according to standard time and standard methods, and never over-long charging. 2. New lithium batteries usually have a certain amount of power when they are in hand, and they can be used immediately, rather than having to be charged before use. From the theory and practice point of view, the first charge of lithium batteries is to use after-use or after-charge. The effect is exactly the same. There is a limit. It is best to charge the battery first if the factory date is more than half a year, because the battery is too low at this time. Third, the choice of power-off charging and power-on charging does not need to be deliberate, because the impact on battery performance is the same. Some lithium batteries are designed to be charged in a standby state, but this situation is relatively rare. Fourth, in terms of consumer electronics, the charging time for lithium batteries is generally 2 to 4 hours. The first charging time for new lithium batteries may be longer because there is no loss of capacity. As a result, it can be fully charged. Charge more It is also useless. The reason has already been mentioned above. If it has to say what uses it has, it is also a side-use. The first charging time of lithium batteries is often transformed into the concept of activation. In some lithium battery manuals, the requirement of using lithium batteries for three full charge and discharge for the first time seems to be activated, but the real purpose is not the same as that of nickel-hydrogen batteries to eliminate the memory effect. The important thing is to eliminate passivation, that is, some lithium crystals will appear during the transfer process of lithium batteries for up to 3 to 6 months, which will affect the activity. The process of eliminating passivation can be carried out during the first charge of the lithium battery, or it can be completed in a normal working environment, without deliberately doing it. Lithium batteries usually take 1-2 months or even longer from leaving the factory to use. During storage, due to spontaneous reactions such as self-discharge inside the battery, the battery consumes part of the power and does not reach the rated capacity value, so it is used for the first time Before, it is best to perform a supplementary charge to prevent customers from mistakenly thinking that the battery capacity is insufficient. The maintenance and maintenance of lithium batteries is very important. The correctness of the charging method directly affects the service life of the battery. We hope that the majority of users will pay more attention to it. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
