How to charge the lithium battery so as not to damage the battery life?

How to use lithium batteries correctly How to use lithium batteries When using lithium batteries, it should be noted that the battery will enter a sleep state after a period of time. When the capacity is lower than the normal value, the use time will be shortened. However, lithium batteries are easily activated. Only after 3 to 5 normal charge and discharge cycles can the battery be activated and return to normal capacity. Due to the characteristics of lithium batteries, it has almost no memory effect. Therefore, do not use special methods or equipment to activate the new lithium battery in the user's mobile phone. This is not only theoretically correct, but there are many discussions about the activation of lithium batteries: the charging time must be more than 12 hours, repeated three times to activate the battery. This statement that the first three charging times exceeded 12 hours is obviously a continuation of nickel batteries (such as nickel-cadmium batteries and nickel-metal hydride batteries). So this is a misunderstanding at first. The charging and discharging characteristics of lithium batteries and nickel batteries are very different. All serious and formal technical documents emphasize that overcharging and overdischarging will cause great harm to lithium batteries, especially liquid lithium batteries. Therefore, it is best to charge according to the standard charging time and method, especially the charging time should not exceed 12 hours. Normally, the charging method described in the mobile phone manual is a standard charging method suitable for mobile phones. In addition, when the battery is fully charged, the lithium-ion mobile phone or charger will automatically stop charging. It is impossible to charge with a nickel coin charger for more than 10 hours. In other words, if the lithium battery is charged, it is also charged in white on the charger. As mentioned earlier, lithium batteries are very fragile, and their ability to withstand charge and discharge fluctuations is much worse than that of nickel batteries, which brings additional risks. In addition, another aspect that cannot be ignored is that lithium batteries are not suitable for overdischarge, and overdischarge is also very detrimental to lithium batteries. This leads to the following question. Charge according to the standard time and procedures, even the first three times; when the phone battery is too low, you should try to start charging as soon as possible; do not use special methods to activate the lithium battery, the lithium battery will be naturally activated when the phone is used normally. In fact, there is not much attention to the use of the battery, in other words, not too much attention. The number of times the battery is used depends more on the individual differences in the way the battery is made, rather than the way the battery is used. In addition to the quality of the battery itself, the battery life is limited. Once the battery leaves the processing line, its lifespan begins to decline. Regardless of whether you use it or not, the life of a lithium battery is 2 to 3 years. One of the important reasons for the decrease in battery capacity is the increase in internal resistance caused by oxidation. Eventually, the resistance of the electrolytic cell will reach a point where the battery is fully charged, but the battery cannot release the stored energy. Many people think that the first use of lithium batteries should be charged for more than 16 hours, which can fully activate the battery, in fact, did not do so, this is the popular nickel-metal hydride battery or nickel-cadmium battery charging method, not suitable for lithium batteries. Because the lithium polymer battery has no memory effect in theory, it can be ignored. So it only takes about 3 hours to charge, there is no problem at all. If it shows that the charging is complete and the external power supply is not needed for the time being, you can unplug the power supply instead of waiting so long. In fact, battery maintenance has always been a hot topic for laptop users, but in fact, the misunderstanding here is that in the final analysis, there are two aspects. One is thinking about not catching up with nickel metal hydride batteries and lithium batteries. The other is more interesting. Cell phones, because cell phones are the first time most users come into contact with the rechargeable batteries of reusable devices. Frequent deep charging and discharging: Lithium battery has small memory. Many people use lithium battery or lithium battery digital products. They like to use the last point of the battery (protection board protection) before charging. In the eyes of many people, this is also a way to activate the battery. . In the use of lithium batteries, charging is called deep charging and discharging. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
