What are the precautions for using lithium batteries in mobile devices?

Precautions for the use of lithium batteries in mobile devices The most important tips for charging and discharging lithium batteries in mobile devices: 1. Charge according to the standard time and procedure, even the first three times. Charge) Plug in the power supply and then plug the output end of the charger into the charging port of the mobile phone (switching and charging can be done) 2. When the mobile phone battery is too low prompt, you should try to start charging in time; the lithium battery is over discharged The most vulnerable! 3. There is no special method to activate the lithium battery. The lithium battery will be naturally activated during the normal use of the mobile phone. Regarding the activation of lithium batteries, many claims are: the charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement that the first three charges should be charged for more than 12 hours is obviously a continuation of the statement that nickel batteries (such as nickel-cadmium and nickel-metal hydride). So this statement can be said to be misinformation at the beginning. The charge and discharge characteristics of lithium batteries and nickel batteries are very different, and I can tell you very clearly that all the serious official technical materials I have reviewed emphasize that overcharge and overdischarge will affect lithium batteries, especially liquid lithium. The battery causes great damage. Therefore, it is best to charge according to the standard time and standard method, especially not to charge more than 12 hours. Generally, the charging method analyzed in the mobile phone manual is the standard charging method suitable for the mobile phone. In addition, lithium battery mobile phones or chargers will automatically stop charging after the battery is fully charged, and there is no such thing as a trickle charge that lasts for more than 10 hours as a nickel battery charger. In other words, if your lithium battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long charging. In addition, on some mobile phones, after charging for a certain period of time, if the charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly detrimental to the life of the battery and mobile phone/charger. At the same time, long-term charging takes a long time, often at night. According to the situation of my country's power grid, the voltage at night in many places is relatively high and fluctuates greatly. As mentioned earlier, lithium batteries are very delicate, and their ability to withstand fluctuations in charge and discharge is much worse than that of nickel batteries, so this brings additional dangers. In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for over-discharge, and over-discharge is also very detrimental to lithium batteries.
