What is the correct way to use the lithium battery for mobile phones?

Pay attention to three points when using lithium-ion batteries: \x0d\ 1, how to charge a new battery \x0d\ When using lithium-ion batteries, it should be noted that after being left for a period of time, the battery will enter a dormant state, when the capacity is lower than the normal value, and the service time will be shortened. However, the lithium battery is easy to activate, and it can be activated after 3-5 normal charge and discharge cycles to restore its normal capacity. It has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not need special methods and equipment in the activation process. It is best to use the standard method to charge this "natural activation" method from the beginning. \x0d\\x0d\ For the "activation" of lithium batteries, there are many arguments that the charging time must exceed 12 hours and be repeated three times. To activate the battery. This statement that "the first three charges should exceed 65,438+02 hours" is obviously a continuation of the statement of nickel batteries (such as nickel cadmium and nickel hydrogen). Therefore, this statement can be said to have been misinformed from the beginning. The charging and discharging characteristics of lithium battery and nickel battery are very different, which can clearly tell everyone. All the serious official technical data I have consulted emphasize that overcharge and overdischarge will cause great harm to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to the standard time and method, especially not more than 12 hours. Usually, the charging method introduced in the mobile phone manual is the standard charging method suitable for this mobile phone. \x0d\ In addition, the mobile phone or charger of lithium battery will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging of nickel battery charger for 10 hour. In other words, if your lithium battery is fully charged, it will be charged in vain. Moreover, none of us can guarantee that the characteristics of the battery charge and discharge protection circuit will never change and the quality will be foolproof. Therefore, your battery will be in danger for a long time. This is another reason against long-term charging. \x0d\ In addition, for some mobile phones, if the charger is not removed after charging for a certain period of time, the system will not only stop charging, but also start a discharge-charge cycle. Perhaps the manufacturer's practice has its own purpose, but it is obviously unfavorable to the life of batteries and mobile phones/chargers. At the same time, charging for a long time takes a long time. It often needs to be done at night, but according to the situation of China power grid, the voltage at night is relatively high and fluctuates greatly in many places. As mentioned above, lithium batteries are very fragile, and their fluctuation resistance in charge and discharge is much worse than that of nickel batteries, so this brings additional risks. \x0d\ In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for overdischarge, and overdischarge is also very unfavorable to lithium batteries. \ 2. When should I start charging under normal use \x0d\ Under normal circumstances, you should charge the battery sparingly according to the principle that the remaining battery is used up, but if your battery can't last all day the next day, you should start charging in time. Of course, if you are willing to take the charger to the office, that is another matter. \ x0d \ \ When you need to charge to cope with the upcoming important events that will lead to busy communication, even if the battery still has a lot of remaining power, you should only charge it in advance, because you have not really lost the life of "1" charging cycles, that is, "0.x" times, which is usually very small. \x0d\ The principle of recharging the battery after the remaining power is used up is not to make you go to extremes. And try to use up the battery of the mobile phone as much as possible, and it is best to turn it off automatically. This practice is actually only on nickel batteries, in order to avoid memory effect. Unfortunately, it is also circulating on lithium batteries today. There has been an example of someone using a mobile phone battery to automatically shut down without charging after warning that the battery is low. Therefore, the mobile phone in this example did not respond during the subsequent charging and startup. I have to send it to the customer service department for repair. This is actually caused by the low voltage caused by excessive discharge of the battery, which makes it not have normal charging and starting conditions. \x0d\3。 \x0d\ To sum up, the most important charging and discharging skills of lithium battery mobile phones are: \x0d\ 1, charging according to standard time and procedure, even for the first three times. \x0d\2。 When there is a low battery prompt, you should try to start charging in time; \x0d\3。 Lithium batteries do not need special methods to activate, and will naturally activate during normal use of mobile phones. If you insist on using the popular method of "charging for the first three times 12 for a short time", it will not have any effect in fact. \x0d\\x0d\ Therefore, all practices that pursue 12 short-term charging and use lithium-battery mobile phones to automatically turn off. It's all wrong If you did it according to the wrong statement before, please correct it in time, maybe it is not too late. \x0d\ Of course, if the protection and control circuits of mobile phones and chargers are of good quality, the protection of lithium batteries is quite guaranteed. Therefore, understanding the charging rules is the key, and some concessions can be made in some cases. For example, if you find that your mobile phone must be charged before going to bed at night, you can also start it before going to bed.
