Analysis of notebook battery life and activation method

1. Regarding the activation of notebook batteries Due to the widespread use of electronic products such as mobile phones and notebook computers, lithium batteries have replaced the nickel-cadmium batteries that were widely used in the early years. But people still continue to use the nickel-cadmium battery application method, and I often see some good and bad companies out there in order to follow along with customers and mislead because they do not understand or are unwilling to spend time with customers to clarify. For example, there is a lot of discussion about activating a new laptop battery: activating the battery three times in 12 hours. It is claimed that the first three charges will take more than 12 hours. This is obviously a continuation of the nickel-cadmium battery, which was incorrectly reported at the beginning. In fact, long-term charging is more harmful to lithium batteries. So do you want to activate the battery? The answer is yes, the demand is activated! However, the end of this process is the manufacturer, not the user, and the user is not the talent. But why does some product manual say that the user should charge and discharge the phone three times before using the phone? Isn't this activation? Due to the characteristics of the lithium battery, it has almost no recall effect. Therefore, during the activation process of the new lithium battery, no special methods and equipment are required, and it can be used normally according to usual habits. 2. Regarding the battery life of notebooks, we all know that the life of a lithium battery is generally 500 normal charge and discharge cycles. But don't mistake it for 500 recharges! The charging cycle refers to the process in which the total power of the battery goes from full to empty, and then from empty to full. This is not the same as a one-time charge. For example, the battery uses 20% of the power on the first day, and then is fully charged with 100% of the power. Suppose I used 80% of the electricity the next day and I filled it up to 100%. There are two charges, but that is one cycle, not two. Therefore, it usually takes several charges to complete a cycle. After 500 cycles, the battery is almost exhausted. The terminal task does not mean that it is broken or unusable, but it has lost its function, for example, it can last more than two hours, and now it runs for half an hour. Therefore, some people take it for granted that if I disassemble the battery and use it less, I can protect it. In fact, whether you use it or not, the battery itself will wear out, generally within 3 to 5 years, even if you don't use it, the battery function will gradually wear out. When you take the battery apart and store it, you only postpone the time for self-depletion a little bit. This means that, assuming that within three to five years, even if your laptop's battery does not reach 500 charge and discharge cycles, its battery life will drop from 2 to 3 hours to about half an hour. In addition, in order to better serve us, it is a waste to buy the battery back, why we should put it on the side of our own consumption.
