1. Polymer batteries have no memory. Excessive charging and discharging will speed up power consumption. According to my work-related experience, it can be said that the mobile phone has to run out of electricity and then recharge the battery. It can be said that it is the top of the wrong opinion ranking list. How can there be such wrong ideas? In fact, rechargeable batteries have memory. If you don’t need to finish charging the battery, it will damage the rechargeable battery. This thing is a characteristic of Ni-MH rechargeable batteries, and this kind of popular rechargeable batteries before lithium batteries were widely used (see No. 3 in the figure) Rechargeable battery) It is true that you must wait for the battery capacity to run out before the battery can be charged, otherwise the storage power of the rechargeable battery will be used less. However, nowadays, products such as smart phones, tablets, notebook computers, multi-digit cameras, and mobile switching power supplies are all used in lithium polymer lithium-ion batteries, which are widely called lithium batteries. This type of rechargeable battery has very different characteristics from the Ni-MH rechargeable battery: there is no memory, and it cannot be charged and discharged too much. The service life of lithium polymer lithium ion batteries is calculated based on the frequency of the battery charging cycle system, that is, the frequency of 0-100% battery charging. To put it simply, if a lithium battery has a service life of 1,000 cycles, in theory, if the battery is charged from 100% to 0% and then recharged from 0% to 100%, it is repeated a thousand times, then this rechargeable battery Similar to die forever! But in fact, the physical characteristics of lithium battery cause damage to the rechargeable battery itself when it is overcharged and discharged. If you often use 0% to charge the rechargeable battery, it is not easy to control whether the rechargeable battery is used for so many times. Circulatory system, and sacrifice immediately ahead of time! Therefore, the first application limitation of lithium battery is that it is definitely not necessary to charge the rechargeable battery completely without electricity. It is best to charge the rechargeable battery as much as possible when the battery can be charged, so that the rechargeable battery can make you grow old. Application of hello! If you often go out for a whole day and cannot charge the battery, and often drag the battery to go home, and the remaining rechargeable battery is less than 10% to charge the battery, then it is recommended that you not buy a mobile switching power supply to carry with you, don't always let you When the rechargeable battery is in ultra-low battery mode! 2. The battery is fully charged and there is no need to rush to unplug it. If you leave and unplug it, you can charge the battery. The second wrong view is that the battery must be fully charged and unplug it immediately. I don't know the origin of this name, but you don't need to go into the source of the wrong view. In fact, whether it is on mobile phones or computers, manufacturers are designing methods to prevent overcharging. When the rechargeable battery is full, it will automatically convert to DC switching power supply to supply the switching power supply on the computer or mobile phone, as shown in the figure. It can be seen that when the battery on the computer is charged to 100%, the MacBookPro will automatically convert to a DC switching power supply, and this situation will be maintained until the rechargeable battery drops to 95%. And if you pay attention to iOS6 (if you have it too...) after fully charged, the battery level on the upper right will also change to a power plug pattern design. This is a reminder to change the phone to an external DC switching power supply system. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
