In order to extend the service life of the battery of a newly purchased laptop, it is very important to maintain it correctly. PHP editor Baicao brings you a notebook battery maintenance guide, introducing various practical maintenance skills and precautions to help you effectively maintain battery health.
As a professional second-hand notebook seller, battery loss has always been a headache. A good battery is inseparable from loss, but good usage habits will make the battery last longer and age more slowly!
1. The biggest problem when using a computer when fully charged is "storage passivation" (storage passivation means that when charging, it shows that it is fully charged, the voltage drops rapidly during use, and the capacity decreases compared with the normal state). Storage passivation occurs when the computer is fully charged. The most serious problem is that long-term use of the computer while plugged in and fully charged will cause passivation. High temperatures will also accelerate the process of passivation and battery aging. But if it is only used at full power for office use, there will be no problem, because now the battery has its own control circuit, which is relatively complete, so there is no need to worry too much. It would be better if you could charge and discharge the battery once a week!
2. If we don’t use the computer’s battery frequently, it’s a good idea to remove the battery. Of course, you should also pay attention to the fact that the battery power should not be too high when removed (it is the same as when it is removed from the machine when fully charged), nor too low (the battery will self-discharge). Storage with low power can easily lead to undervoltage due to self-discharge, which can cause great damage to the battery.
3. Having said that there are many positives, what is a scientific charging method? First of all, when using the battery, try to reduce the depth of charge and discharge as much as possible. That is, the lower the battery's depth of discharge, the more charges the battery can achieve. For example, if the battery level drops from 90% to 80%, we will charge it. Secondly, the battery should not be overcharged and should be kept at about 40% as much as possible. At the same time, the battery temperature should not be too high. When the battery temperature is low and the battery power is maintained at about 40%, the loss of battery capacity within one year is very limited. On the contrary, if the battery is 100% fully charged and in a very high temperature environment, the loss of battery capacity will be very obvious.
Of course, we can’t control it so accurately when using it, and no one can have so much energy to keep an eye on the battery. Therefore, you only need to remember the following points:
First: When the battery is used frequently, we can charge it at a convenient time.
Second: When the battery is used occasionally, we can discharge the battery several times regularly.
Third: When the battery is not used frequently, we only need to shut down the battery when 80% of the battery is used, unplug the battery and store it in a cool place with a low temperature, activate the passivated electrodes, and charge it at the same time. Provide the electricity needed for self-discharge in the next storage period.
ps: Lithium batteries do not have a memory effect. They are more afraid of overcharging or over-discharging. Currently, the current batteries have their own control circuits, and they are relatively complete. We will not have any big problems in normal use.
Summary: If the methods listed above are out of convenience, there is no need to do them. After all, the laptop is just a productivity tool. You can use it how you want and there is no need to provide it. Normally, TB can buy batteries and that’s about it. Hundreds of dollars
1. In Windows Power Management, set the power usage plan to "Always on" and turn off the following options. All menus related to turning off the device are set to "Never".
2. Take out the battery and leave it for half a month to a month, so that the battery will be exhausted and the power supply will be used to maintain the operation of the microprocessor module. When the module is charged again, it will automatically return to its original, newer state.
3. Disassemble the battery, disconnect the control circuit from the battery, and discharge the circuit board. An artificial method to restore the initial state by forcing a circuit reset.
4. In the "Alarm" tab, set the "Low Power Alarm" to 10%. If the operation is set to "Do Not Operate", set the "Severe Power Lack Alarm" to 3%. Adjust the screen brightness during "Standby" to the lowest level.
5. Confirm that all windows have been closed and all data from previous work has been saved. Check whether the battery charge exceeds 80%, unplug the power source and all external devices. At this time, wait for the laptop to automatically discharge. After discharge, the laptop will automatically shut down and plug in to charge the laptop. Be sure to wait until full before turning on the power, and reset settings before calibrating.
6. When you use the computer for a long time, try to adjust the battery to energy saving rather than high efficiency, so that the battery can be better maintained.
1. The life of the laptop battery should be maintained from the beginning of use. When you first buy the laptop, you should use up the battery and then fully charge it, then fully charge it and then use it up. Repeat this three times, which will help activate the battery better.
2. If possible, try to use an external power supply. This will reduce the chance of battery use, and the battery will be better maintained and have a longer life.
3. Avoid charging for too long. The battery has a certain memory effect. Charging for too long will cause damage to the battery.
4. When using the battery, you must protect it from exposure to sunlight, moisture, corrosion from chemical liquids, and avoid contact between battery contacts and metal objects.
5. In addition to recharging after running out of power 3 times before starting, do not recharge the battery below 10% during normal use, otherwise the service life of the battery will be shortened.
6. If the laptop battery is not used for a long time, there is no need to unplug the battery. You only need to use the battery once a month to ensure that the battery is in good storage condition and will not damage the battery.
For most laptop users, battery life is a very important consideration. Generally speaking, the life of a laptop battery will begin to decline after 300 to 500 full charges and discharges. Mastering this basic rule can help us better maintain the battery.
Overcharging is one of the main causes of shortened battery life. Connecting to the power source for a long time and continuous charging will cause the battery capacity to decrease sharply. To prevent this from happening, we can unplug the charger when the battery is close to 100%.
Similarly, over-discharging can also damage the battery. While an occasional full discharge can help calibrate the battery's condition, long periods of full discharge will accelerate battery aging. The best practice is to start charging when the battery is below 20% to avoid complete depletion of battery.
Temperature also has a great impact on battery life. Temperatures that are too high or too low can have a negative impact on the battery. Therefore, try to avoid using your laptop in extreme temperatures as this will help extend battery life.
Reasonable usage habits are also crucial to maintaining the battery. For example, reducing the need for graphics processing and video playback can save battery energy; installing some tools to help manage battery is also a good choice.
This article can help readers better understand how to maintain laptop batteries, extend battery life, and reduce the inconvenience caused by battery aging.
1. (The most important thing) Don’t use batteries if it can be plugged in.
2. Keep the battery power between 30% and 80%
Let me focus on explaining the second point. Keeping it between 30% and 80% does not mean that the battery is used up to 30% like you usually use a mobile phone, and then Plug it in and charge it to 80%, and repeat. Instead, you need to set the battery charging threshold in the laptop BIOS so that when it reaches 80%, it will stop charging the battery and instead use the power supply directly. The advantage of this is that it will not increase battery cycles, and it will not keep the battery in a high-power state for a long time. These two points can effectively prevent battery aging and bulging.
To be honest, I actually read the sentence of the topic leader three times before I understood what it meant.
When it comes to how to maintain laptop batteries, there are basically the following principles:
1. You can unplug the battery when it is frequently plugged in and used
2. When the battery is not used for a long time, it should be fully discharged and then fully charged every 30 days or so. 1 time
3. Don’t drain the battery when using it frequently. It can be charged before there is about 20-30% left.
But I still want to say that whether it is for office or gaming, a laptop is a tool after all. Don’t It has become a burden for maintenance, and I have stopped eating because of choking. Use it as you want, just pay a little attention, and don't let it influence you.
1. For lithium-ion batteries, no activation is required, just use them directly.
2. When there is no external power supply, if the card in the slot is temporarily unavailable for the current working state, it is recommended to remove the card first to extend the battery life.
3. Avoid exposing the laptop and battery to the sun. The best working environment for the battery and laptop is 10-30 degrees.
4. Do not let the battery come into contact with water or other liquids.
5. Please do not unplug the external power supply during the charging process of the battery until it is fully charged; when using a laptop in an environment that can provide stable power supply, it is incorrect to remove the battery to extend battery life.
6. Please do not attempt to disassemble or modify the battery. Doing so may cause the battery to explode or leak internal liquid. Batteries not specified by Lenovo, and disassembled or modified batteries are not covered by the warranty.
7. Do not throw batteries into landfill garbage. When disposing of batteries, please follow local laws or regulations.
8. For models with removable batteries: If the computer will not be used for a long time, it is recommended to unplug the battery and store the battery separately. Batteries should be stored at room temperature (-10-35 degrees) and charged to 30% to 50%. It is recommended to charge the battery every 1 month or so to prevent excessive discharge.
1. Charge the laptop battery correctly.
Nowadays laptop batteries are all lithium batteries. There is no need to completely drain them before recharging them. This is not good for the battery and will actually cause damage.
Correct maintenance method: It is best to charge the battery every time the remaining power is between 10% and 20%. The number of battery charge and discharge is fixed, which is good for the battery.
2. When the notebook is connected to DC power supply, it is best to remove the battery.
When the notebook is connected to the DC power supply, it will not cause any harm to the battery if it is not unplugged, because the battery will not receive any power injection after it is fully charged, and all power will be transferred directly to the notebook's power supply system.
Correct maintenance method: When the laptop is running at high speed, internal overheating is harmful to the battery. It is best to remove the battery and use DC power.
3. Laptop battery working environment
Do not use laptop batteries in the sun or at sub-zero temperatures. This will not only greatly reduce the battery life of the laptop, but also damage the life of the laptop battery. Try to only use laptop battery power in cool places with suitable temperatures.
4. It is best not to use laptop batteries when you can use DC power.
After one use, the battery life will be shortened. Minimize the number and duration of battery use.
5. If the laptop battery is not used for a long time, it can be charged to 40%-50%. Remove the laptop battery, place it in a sealed plastic bag, and store it in a dry environment. Laptop batteries that have been disassembled for a long time should also be fully charged and discharged at least once a month.
6. It is best to turn off the computer when charging and do not unplug the power supply during charging. Replace your laptop battery every two months.
7. Use the dedicated charging equipment provided with the notebook and do not use other power devices to charge the notebook.
8. Avoid human impact, disassembly, falling, heating or short circuit.
1. When using a new battery, you don’t need to charge it first, because it has residual power before leaving the factory, so put it into the laptop for use first, and then use it until the laptop prompts that the battery is low, then connect the external power supply and start charging for the first time.
Nowadays, the batteries sold by regular manufacturers are not activated, so there is no need to charge it three times, each time for 12 hours or more, as everyone thinks.
But at least the first time you charge it, you can charge it for a little longer. The charging indicator light on the laptop goes out and shows that it is fully charged (different manufacturers are different, some manufacturers always light up to indicate full) and then charge two more times. Three hours is enough.
In addition, it is very important that during the first two charging times, it is best not to use the computer and do not use it while charging. 2. In the process of using the battery, if the battery uses a certain amount of power, it is best to recharge it after using it up. That is to say, do not recharge the battery before it is fully used. For example, a 6-cell battery should be able to stand by for 3 and a half hours. If you have used it for an hour without plugging in the adapter (charger), there should be 60~70% of the power at this time. At this time, do not plug in the charger and start charging. It is best to put the 70% Recharge after use up. Recharging midway has the greatest impact on the life of the battery. Having said so much, in fact, in a simple sentence, do not charge a battery that is half used, wait until it is used to about 10% before charging again.
3. Some people take off the laptop battery when using the adapter. They think it should be protected first and then used when going out. This is also not advisable. If you don’t use the battery for a long time, it will be bad for the battery. In addition, it will be harmful to the battery. Laptops are also bad.
Because the electric ions in the battery need to flow frequently to keep the battery core active. If the electric ions in the battery are not allowed to flow for a long time, the battery content will gradually lose its effectiveness, and the battery will not be able to store electricity normally, and it will not be fully charged with electrons. . 4. The battery's standby time is a variable, which means it is not a fixed manufacturer's nominal time, because the manufacturer's standby time of several hours generally just refers to the theory of not doing anything after turning on the phone, and then waiting for the battery to run out. In actual use, usually just typing and surfing the Internet, it can be close to the manufacturer's nominal time, but if you watch movies or play games, this time will be reduced, because when watching movies and playing games, the CPU and graphics card of the two computers Large electricity consumers on the Internet will begin to work at full load, and their electricity consumption will increase.
If you only use simple basic functions such as surfing the Internet and typing, these two accessories are basically in a power-saving state.
The same goes for other accessories.
Don’t think that the sudden shortening of time means there is something wrong with the battery.
Open the win10 interface in the lower left corner. Find a built-in APP called "ASUSBattery Health" (if you don't have it, you can download it from the Microsoft store), turn off the battery maintenance mode and change it to the first one "Always full for outdoor use"
