Battery activation is called power scale calibration on Lenovo power management software. When Everest is used to test the power supply on the PC side, there is a design capacity, followed by the full charging capacity. If the two values are the same, Then you will see that the battery loss item below is 0%. Generally speaking, the fully charged capacity of the battery that has just left the factory or has not been maintained in time for a long time will be less than the design capacity. At this time, you will see that the battery loss is 1%. This means that the battery is not fully charged, and we need to fully charge and discharge it (after full discharge, charge continuously for 12 hours or more) It is beneficial to fully develop the potential of battery. This process of complete charging and discharging is called activating the battery. The power management software such as Lenovo Thinkpad has a power scale calibration function with similar principle.

Personally, I think some batteries with old technology, such as NiMH, should be activated. The theory of lithium-ion battery is to excite because a layer of SEI protection layer should be formed at the negative electrode. But this process has actually been completed in the production test stage. Personally, I think that consumers' misunderstanding of battery has caused such service.

Your mobile phone battery is starved to death. It can't be powered on and charged. At this time, it needs to be activated! First of all, the so-called starvation is the phenomenon that the battery cannot be recharged when the battery has been out of power or the power is very low. Then there are two ways to activate it. First, it can be activated after about 20 minutes of universal charging. The second is to provide the mobile phone repair shop with a professional voltage slightly higher, such as a 12V power supply to activate. Specifically, 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 minutes to power it up and open it! Finally, after activation, it can be charged with the same direct charge as the original one. It is unclear whether it will have a significant impact on the service life.
