About laptop batteries, experts help

I just bought this book, Dell's 1400, like you, I feel very distressed, and I don't feel at ease. After reading the above article, I can be relieved, (*hee-hee......

Generally speaking, there is no need to take off the battery after three activations. Because when the laptop is connected to the external power supply and plugged in the battery when in use, as long as the external power supply is used, the laptop will automatically cut off the power supply from the battery to the laptop, and all the motherboard can do at this time is to charge the battery. When the battery is fully charged, the battery will be automatically cut off from charging, which plays a role in supersaturation protection.

Today's batteries are lithium batteries, and the battery, as a physical element, is susceptible to various factors (dust, oxygen, etc.) in the working environment, and the main reason for battery loss is the increase in the internal resistance of the battery caused by oxidation. If you start from the chemical aspect, even if the lithium battery is removed and not used, the activity will be reduced no matter how you preserve its chemical activity (so some people recommend freezing, just to preserve his activity as much as possible, but in doing so, on the other hand, the physical structure of the battery is damaged, so there must be gains and losses), so when the battery assembly is finished and walks off the production line, its internal life clock will start to move, even if you put the battery aside, it is also wearing out, and the life is shortening.

I only use my laptop at home (I have a computer in my office at work), and I haven't taken off my battery since I figured it out.

When I first bought this book, I didn't know how to deal with the battery problem.,So according to what the Internet said.,How to charge and discharge.,How to save something.,Who expected that after a year of use, the standby of this book will change from more than 2 hours to an hour and a half.,The next software came down to test the battery.,Found that my battery was damaged and lost 1/5th.。 Later, I didn't care about the battery, and I kept it on the book (the external power supply was rarely broken), and now I have used it for half a year, and now the battery is still damaged as before. The point here is that if you take it off, it may cause the battery to oxidize and age faster than if you put it on the book.

Maybe you still suspect that this is accidental, but what I can tell you is that my sister also uses a notebook, which has been purchased longer than mine for two years and has never been removed, and I did a test some time ago, and her battery damage rate is less than 10% (such things are everywhere around me, I advise my friends not to take the battery, and their battery is not problematic now). If you want me to say, the laziest way is also a good way, and LZ doesn't have to worry too much about the battery. If you are really not at ease, you can use the next software battery mon or battery eater pro 2 to regularly test the health status of your battery, or you can also ask the after-sales personnel, but I believe that the answer they can give you will be the same as mine.

Battery problems, it is recommended to go to a repair center.

If it is not that the battery has been used for a long time, it is recommended to turn off the automatic alarm of Windows, fully charge the battery, and use it until you shut it down, and it will get better after three or five times. If the battery cell is aging, change the battery, or change the core, but the current core needs to be unlocked, and DIY is more difficult.
