How to maintain the laptop battery

The battery of the notebook is the most vulnerable part in The Notebook, which needs to be replaced every-times. So maintaining the laptop battery is the core of maintaining the laptop :-)

First, I got a new battery. Many users charge the lithium battery for 12 hours or more three times as prompted by the seller. There is also a lot of debate on the Internet, but I found in actual use, in fact, this is not necessary for the laptop battery. Why? Merchants say this is to fully activate the battery activity and completely wake up the new battery. It sounds like this is a sound and trustworthy reason, but have you ever thought about it. If the notebook battery has not been fully activated by the manufacturer, such a product can be said to be only a half product. It is impossible for every user to master the battery activation technique, but it is also impossible in reality. Therefore, the battery has been fully activated by the manufacturer before leaving the factory. So is 12 hours of charging favorable for battery usage? Here I give a negative answer. The current laptop battery has a sound power management circuit and charging management system. When the battery reaches saturation, the control circuit automatically switches to the short circuit status, so the future time is just a waste of time. How can we activate the battery activity? In fact, the manufacturer activates the battery by charging and discharging the battery for a long time without overload protection. Therefore, it is unnecessary to charge the first three times for 12 hours.

In this case, many users are very confused about the use of the battery, and should not be charged until the battery is fully exhausted. The answer to this question should be like this. If you can do this, it must be a good thing, but the premise is that you are not too troublesome. Of course, what I am talking about here is not excessive discharge. Practice has proved that excessive discharge is definitely harmful to the battery and it will shorten the service life of the battery. Therefore, when the notebook prompts that the power is low, it can be charged in a timely manner. Some merchants have repeatedly declared that their lithium battery has no memory effect, which is extremely irresponsible. So when your battery has a lot of power, it is better not to charge, because the memory effect does exist.

Third, for the battery that is not used for a long time, it is recommended to charge 40-50% of the power, placed in a low temperature shade, the following parameters can illustrate this problem.

Storage Temperature	40% charging status	100% charging status
0 degree	98% (one year later)	94% (one year later)
25 degrees	96% (one year later)	80% (one year later)
40 degrees	85% (one year later)	65% (one year later)
60 degrees	75% (one year later)	60% (3 months later)

(Percentage is the percentage of the relative initial value of the current saturation state)

Of course, it is best to take out the battery once a month to ensure that the battery is in good storage and not to completely drain the battery.

Fourth, in the usage instructions of the laptop, is it necessary to "use it once a month later. The lithium-ion batteries used in laptops are generally equipped with management chips and charging control chips. The management chip has a series of registers, including capacity, temperature, ID, charging status, discharge times, and other values. These values gradually change in use. I personally think that the main function of "One month after use should be fully filled" in the usage instructions of the laptop should be to correct improper values in these registers, so that the battery charging control and nominal capacity are consistent with the actual situation of the battery. Therefore, this kind of work cannot be omitted. After all, high-priced laptops are still charming and noble.

Finally, let's talk about how to make the battery of the current version more persistent. Now that you have bought a notebook, you need to use it. The battery is a consumable and will inevitably be decommissioned as time goes on. How can this battery be used longer? Power-saving technology? Sleep? Hold the hard disk? Reduce the screen brightness? All kinds of methods seem to be able to increase the so-called time extension. But have you ever thought that such a time extension makes sense? I don't run any program on this book, don't turn on the display screen, don't let the hard disk turn, I can't reach a longer time. It is absurd to think of such an approach. A notebook is used instead of a magnificent decoration. Therefore, I suggest that you use your notebook instead of using it. Maybe two years later, the notebook market is another place, and your capital has also gone to the ranks of retired users. As long as you pay attention to the daily usage habits of the battery, you can use the battery normally.
