First, the first time you use the battery, the first three need to charge 12 hours?
This is completely unnecessary. Because today's laptops have a complete power management circuit and charging management system, when the battery reaches saturation, the control circuit will automatically switch to the open circuit state, so as long as it is full, it does not mean that the longer you charge, the longer you can use it. of.
Second, in order to prevent the memory effect, do you have to use the electricity to charge it?
It is not necessary to discharge the battery before each charge, and it is harmful. Because the practice proves that the deep discharge of the battery will unnecessarily shorten the battery life, it is recommended that the battery can be charged when it is used about 10%. Of course, when there is still more than 30% of the battery power, it is best not to charge, because the memory effect does exist.
3. When inserting AC power, take the battery down to prevent repeated charging and discharging?
My advice to you is: no! Of course, you can use the natural discharge of the lithium-ion battery to refute me, saying that after the battery is naturally discharged, if there is power supply, repeated charging and discharging will occur, reducing the battery life. And I give you the reason to "do not use" this answer:
1. Now the notebook's power control circuit is designed with this feature: when the battery reaches 90% (such as most HP models) or 95% will be charged, and the natural discharge to reach this capacity for 2 weeks to a In the month, when the battery is idle, it takes less than one month to fully charge and discharge to maintain the capacity of the battery. At this time, you should be concerned that the battery should be exercised instead of being recharged after being idle.
2. Even if the battery is "unfortunately" recharged, the loss will not be much greater than the power loss caused by the battery not being used for a long time.
3. Your data is much more precious than your battery or even your notebook. Sudden power outages not only hurt your notebook, but the irretrievable data is too late to regret.
Fourth, long-term storage of batteries need to be fully charged?
It is clear after reading the following table: (The percentage is the percentage of the current saturation relative to the initial value)
Storage temperature 40% state of charge 100% state of charge 0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (one year later)
40 degrees 85% (after one year) 65% (one year later)
60 degrees 75% (after one year) 60% (after 3 months)
Obviously, if you want to save the battery for a long time, it is best to put it in a dry and low temperature environment and let the remaining battery power be around 40%. Of course, it is best to take the battery out once a month to ensure that the battery is well preserved, and that the battery is completely lost and the battery is damaged.
5. How to extend the use time of the notebook as much as possible during use?
1. The screen brightness is lowered. The LCD screen is a large power consumer, and the brightness reduction can effectively extend the use time.
2. Turn on the power saving functions such as SpeedStep and PowerPlay. Today's notebook processors and display chips have the ability to reduce operating frequency and voltage to extend the use of time, open the appropriate options can greatly extend battery life.
3. Use the slowdown software of hard disk and optical drive: such as NERO DriveSpeed, PowerBooster and other software can reduce the speed of the drive such as optical drive, hard disk, etc., and can effectively reduce the work of the notebook.
From the day the laptop was born, the debate about the battery has never stopped, because the use of durability is a very important technical indicator of the notebook, and the capacity of the battery determines this important indicator of the notebook. How to use it to maximize the efficiency of the battery and extend the life of the battery? Below, we will list a few misunderstandings that we often encounter: (unspecified for the most commonly used lithium-ion battery)
