Hello everyone, Lin Fei to answer the above questions, notebook battery maintenance of the top ten tips, notebook battery maintenance many people do not know, now let's take a look!

With the development of science and technology, computers have become quite popular in our country. It can be said that every family has a computer, so everyone must take good care of their own computer and will think of many ways to maintain their own computer. With the development of notebook computers, everyone has a personal computer, and everyone must take good care of notebook computers. Speaking of the maintenance of notebook computers, I would like to talk about the maintenance of notebook batteries. After all, batteries are important. Next, we will follow

Laptop battery

At present, most of the commonly used notebook batteries in the market use lithium-ion batteries. So what is a lithium-ion battery? Lithium-ion battery is a kind of rechargeable battery, which mainly depends on the movement of lithium ion between positive and negative electrodes. In the process of charge and discharge, Li is embedded and detached back and forth between the two electrodes: when the battery is charged, Li is detached from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Usually, materials containing lithium are used as electrodes. It is the representative of modern high-performance battery.

Why do lithium-ion batteries replace Ni-MH and Ni-Cr batteries? As the memory ability of lithium-ion battery is not obvious, it can be charged and discharged at any time, and users can charge and discharge anytime and anywhere. However, even if the memory of the lithium-ion battery is not obvious, the user's random charge and discharge will affect the life of the battery itself. According to the current authoritative test results, the life of general lithium-ion battery is about 1000 times of charge and discharge. Therefore, if there are no special circumstances, friends should put down their butcher's knives and reserve their delicate small lithium batteries for the time being.

Misunderstanding of Lithium Battery maintenance in Notebook

Battery maintenance has always been a hot topic for notebook users, but there are many misunderstandings in the maintenance process. In the final analysis, it comes from two aspects, one is that "thinking has not kept pace with the times (the transition from Ni-MH battery to lithium battery)", and the other is from mobile phone. Because mobile phones are the first devices that most users come into contact with using rechargeable batteries, they will naturally extend some of their habits of charging to laptops, which makes many users misunderstand. Next, the author will simply

The first charge must last 12 hours.

I believe many friends will hear the dealer tell you how to maintain the battery when buying a laptop. It takes 12 hours to charge for the first time, otherwise the battery will be affected. But I don't think it's appropriate, because today's laptops generally use lithium-ion batteries, and when laptops are full of lithium batteries, the charging current of most machines will be automatically cut off. Even if you continue to recharge for hundreds of hours, the state will not change. On the contrary, too long charging time will affect the battery life. In terms of current battery charging time, the slowest machines usually take about six hours to complete, and the rest of the "charging" is just a waste of their own time.

Myth 2: 3360 this notebook needs to be recharged three times before it can be used properly.

This phenomenon is unnecessary unless the battery of the product purchased by the user is more than a year or more, because the battery of the notebook battery is usually activated when it leaves the factory, storing part of the power for the user to test-drive. So users in the purchase of notebooks, the battery is already activated products, charge and discharge three times to increase the loss of the battery is just not necessary.

Misunderstanding: the battery needs to be calibrated regularly and charged and discharged every half a month or once a month.

This method is very suitable and necessary for the old Ni-MH battery, because the memory effect of the old battery is stronger, this method can ensure the service life of the battery. But for lithium-ion batteries, this cycle is too frequent. Although the memory effect of lithium-ion battery has not been completely eliminated, it has greatly weakened the memory effect. If you use the battery regularly, you should discharge the battery to a relatively low level (about 10-15%) and charge it, but if you overuse it (0-1%), it will cause a lot of damage to the lithium battery. So generally speaking, it is enough to do this once every two months. If you rarely use batteries, you can only do it every 3 months.

Myth 4: correction can improve battery capacity.

The so-called notebook battery calibration is to charge and discharge the battery deeply when the actual capacity of the battery is different from that recorded in the control circuit, so that the control circuit can refresh the record and make it close to the actual situation of the battery. This operation can only tell the user to see the actual capacity of the battery, not an increase in capacity. The key factor is the actual capacity of the battery, because if the actual capacity of your battery is higher than that recorded in the control circuit, correction can increase the apparent capacity of the battery. On the contrary, if the actual capacity of the battery is lower than that recorded in the control circuit, the correction will reduce the apparent capacity of the battery. This is why many people argue about the effect of correction. So I hope you will not be deceived by these two data, because the correction shows the true capacity of the battery and eliminates the deviation between the battery and the control circuit. As for whether the displayed capacity will increase or decrease, this is the state of the battery itself, not the result of your correction.

Myth 5: compatible adapters can also be used.

A laptop consumes several times more power than a mobile phone. If a mobile phone lasts only 8 hours, it can only be said that the battery of the phone is relatively poor. For the original, the 8-hour battery life is quite excellent. In addition, the laptop adapter also bears the power demand of the laptop while charging, so the laptop actually does not have a compatible adapter. The compatible adapters mentioned by the maintenance staff are only for those users who are greedy for bargains. Here, I do not encourage users to buy, because the current, voltage and even power interface of each laptop are different. Although there are some compatible chargers on the market and the price is very cheap, there are a lot of problems in using them. For example, the adapter interface is the same, but the voltage and current are lower than the machine's standard value. When the machine is working at full speed, the battery may not get enough charging current, which does great harm to the battery. On the contrary, if the voltage and current are much lower than the standard value, there may be a situation in which the machine cannot or can be turned on at all.

Myth 6: batteries need to be fully charged or photovoltaic for storage.

Whether it is fully charged or stored, it is not a very good way to store the battery, because the method of storing the battery after photovoltaic storage for a long time will cause the cell to lose its activity and eventually make the battery not rechargeable; although the battery fully charged preservation will not make the battery useless, but the security risks are great, so the author does not advocate here. If the user wants to save the battery, it is best to discharge the battery to about 40% of the battery. At the same time, the lithium battery is afraid of humidity and high temperature, so it should be stored in a cool and dry place, but the temperature should not be too low. Otherwise, the capacity will be greatly reduced, about 20 degrees Celsius is the ideal storage temperature. Let me show you a table: the percentage is the percentage of the saturation state relative to the initial value at that time.

Storage temperature 40% charging state 100% charging state

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)

Myth 7: add your own battery when the electronics are about to be scrapped.

This phenomenon generally occurs in enthusiasts, because they know about notebook accessories, but it is this practice that leads to the complete scrapping of batteries, because some of the major manufacturers will do so when the machines leave the factory, so a self-locking function will be set up before leaving the factory. Once the battery is out of control circuit, the circuit will enter the self-locking state. Only by using specific means can it be untied. Before that, the control circuit will not work, that is to say, the battery is equivalent to scrapped, the notebook battery cell is not a dry battery that can be changed at will, if you have to change the battery, then please go to the professional after-sales maintenance point to replace it.

Myth 8: remove the battery when plugging in AC power to prevent repeated charge and discharge

This phenomenon is very common, many users deal with batteries in this way, but the author believes that this practice is totally unnecessary. First of all, at present, there is a characteristic of notebook power circuit control in the market, that is, when the notebook battery is 90% or 95%, it often takes 2-4 weeks for the notebook battery to discharge naturally. Then the battery must be fully charged and discharged after it has been idle for a long time. What you should be concerned about at this time is that the battery should exercise instead of being recharged after being idle. Secondly, the author believes that even if the battery is recharged and discharged, the loss will not be much greater than the loss of battery power caused by you often not using the battery. Finally, the author would like to remind everyone that the data in your notebook is important, or is it that a little bit of battery power is important? if you do not plug in the battery when the power is suddenly cut off, it is likely that it will cause unnecessary damage to your notebook and some important data will not be recovered.

Misunderstanding and correct maintenance methods of notebook battery

1. First of all, if users want to make the battery of the notebook last long, they need to have a good start. When we buy a notebook, the battery should have some remaining power, which is for the user to use when checking the machine (if the user finds that the battery is full, then prove that the machine has been used). At this time, you should not use the external power supply, use up the remaining power in the battery until it is turned off, and then use the external power supply to charge.

two。 Don't charge the battery on rainy days: there is often thunder on rainy days, and the instantaneous current shock caused by lightning is extremely disadvantageous to the battery. In addition, a stable voltage is also particularly important in the use of notebook batteries. Users should try to avoid connecting laptop power adapters and high-power appliances (such as air conditioners, refrigerators, washing machines) to the same power outlet.

3. Regular battery maintenance: if you cannot guarantee that the battery will be thoroughly clean and recharged every time, it should be charged and discharged at least once a month, or regularly maintained with BIOS's built-in battery calibration function, which is good for prolonging battery life.

4. If some users do not use the battery for a long time, they need to charge the battery to more than 50% of the battery for storage, which is beneficial to the subsequent use of the battery. In addition, in the process of storage, we must pay attention to the indoor temperature, too high or too low temperature on the battery is also relatively great, the best storage temperature is about 20 degrees.

The above is the notebook battery maintenance introduction, we can know that most notebook batteries are lithium batteries, lithium battery memory is not very good, so it can be charged and discharged at any time, but it is also easy to cause damage to the battery, so the above also listed a lot of notebook battery maintenance misunderstandings, we must pay attention to these misunderstandings, because these misunderstandings we are used to I don't think there will be any big problem, but in fact, these habits are the root cause of computer damage. I hope the above introduction is helpful to you.

At the end of this article, I hope it will be helpful to you.
