How many times can the battery of HP notebook be reused? How to maintain.

It's the first time to use the battery. Do you need to charge it for the first three times 12 hours? This is completely unnecessary. Because notebook computers now have perfect power management circuits and charging management systems, when the battery reaches saturation, the control circuit will automatically switch to the open circuit state, so it is useless even if the charging time is longer. In order to prevent the memory effect, should we use up the electricity before recharging? It is unnecessary and harmful to discharge the battery before each charge, because practice has proved that deep discharge of the battery will unnecessarily shorten the service life. It is suggested that the battery can be recharged when it is used to about 10%. Of course, when the battery still has more than 30% charge, it is best not to charge it, because the memory effect does exist. Should the battery be taken out when AC power is plugged in to prevent repeated charging and discharging? My advice to you is: no, you may refute me with the natural discharge of lithium-ion battery, saying that if the battery discharges naturally, it will be repeatedly charged and discharged when there is a power supply connection, which will reduce the service life of the battery. And the answer I gave you was "no" for the following reasons: 1. At present, the power control circuits of notebooks are all designed in this way: the battery will only be charged if it reaches 90% (such as most models of HP) or 95%, and the time to reach this capacity through natural discharge is 2 weeks 1 month. What I want to say next is that the battery is idle for about a month and needs to be fully charged and discharged to maintain the battery capacity. At this time, you will 2. Even if the battery is "unfortunately" charged, the loss will not be much greater than the power drop caused by not using the battery for a long time. Your data is much more precious than your battery or even your notebook. Sudden power failure is not only harmful to your notebook, but also too late to regret irreparable data. Does the battery need to be fully charged for long-term storage? It is clear after reading the following table: (percentage is the percentage of saturated state relative to the initial value at that time) Storage temperature 40% State of charge 100% State of charge 0 degree 98% (one year later) 94% (one year later) 25 degree 96% (one year later) 80% (one year later) 40 degree 85% (one year later) 60. 60 degrees 75% (one year later) 60% (three months later) Obviously, if you want to store the battery for a long time, it is best to put it in a dry and low-temperature environment, and the remaining power of the battery is kept at about 40%. Of course, it is best to take it out once a month, which can not only ensure the good storage state of the battery, but also prevent the battery from being completely lost and damaged. How to prolong the use time of notebook as much as possible when using it? 1. Turn down the screen brightness. LCD is a big power consumer, and the decrease of brightness can effectively extend the service time; 2. Turn on power-saving functions such as SpeedStep and PowerPlay. The current notebook processor and display chip have the function of reducing the working frequency and voltage to prolong the service life, and opening the corresponding options can greatly prolong the service life of the battery; 3. Use the deceleration software of hard disk and CD-ROM drive. NERO DriveSpeed, PowerBooster and other software can reduce the rotational speed of CD-ROM drives, hard disks and other drives, and can also effectively reduce the power consumption of notebooks. 4. Make good use of standby, hibernation and other functions. When the computer is not used for a long time, the notebook can stand by or sleep, which saves electricity and prolongs the service life of the computer. The debate about batteries continues.
