How to activate mobile phone and laptop lithium battery starved to death

Battery activation is called power ruler calibration in Lenovo's power management software. When using Everest to test the power supply on the PC side, there is a design capacity, and the bottom is followed by the full charge capacity. If the two values u200bu200bare the same, you will see that the battery loss item underneath is 0%; generally speaking, the battery loss item is 0%. Or the full charge capacity of the battery that has not been maintained for a long time will be less than the design capacity, and you will see that the battery loss is 1% at this time. This means that the battery is not completely overflowing, and we have to perform full charge and discharge (after full discharge, uninterrupted charging for 12 hours or more) to fully develop the potential of the battery. This complete charging and discharging process is called activating the battery. Power management software such as Lenovo Thinkpad has a power ruler calibration function with similar principles. I personally feel that some old technology batteries such as NiMH need to be activated. Lithium battery theory is to be intensified because a protective layer of SEI is formed on the negative electrode. But this process has actually been completed in the processing and detection stage. I personally feel that consumers’ misunderstandings about batteries have caused such services. Your mobile phone battery is starving to death, and it cannot be turned on and cannot be charged. You must activate it at this time! First of all, the so-called starvation is the phenomenon that the battery cannot be recharged when the battery has been discharged or the battery is very low. Then there are two methods for so-called activation: one is to use a universal recharge for about 20 minutes to activate. The second is to provide a professional mobile phone repair shop with a slightly higher voltage such as a 12-volt power supply to activate. The details are to put the positive and negative poles of the power supply on the positive and negative poles of the battery for tens of seconds or even a few minutes to power on it and get it through! Finally, after activation, it can be charged with direct charging the same as before. It is not known whether it will have a distinct impact on the lifespan.
