1. How to charge new batteries In use in lithium-ion batteries, the battery is placed in a sleep state, at which time capacity is below normal, the time of use is shortened. However, the lithium-ion battery is easily activated, and the battery can be activated as long as it passes through 3-5 normal charge and discharge cycles, and normal capacity is restored.

Due to the characteristics of the lithium-ion battery itself, it determines that there is almost no memory effect. Therefore, the new lithium ion battery in the user's mobile phone is not particularly method and equipment. Not only theory is theoretical, from my own practice, from the beginning, the standard method is used to charge this natural activation method is the best.

About the problem of activation of lithium-ion batteries, many statements are: charging time must be more than 12 hours, repeated three times in order to activate the battery. This first three-three charging should be charged more than 12 hours, which is obvious to continue from nickel batteries (such as nickel-cadmium and nickel hydrogen). So this kind of saying, you can say that the beginning is misuse.

The charging and discharging characteristics of the lithium-ion battery and nickel battery have a very big difference, and you can tell you very clearly. All serious formal technical information I have been inspected emphasizes that the charge and over-discharge will pairs of lithium-ion batteries, especially Liquid lithium-ion battery causes huge damage. Therefore, charging is preferably charged according to standard time and standard method, especially for more than 12 hours of long charging.

Generally, the charging method described in the mobile phone manual is to suit the standard charging method for the mobile phone. In addition, the mobile phone or charger of the lithium-ion battery will automatically stop after the battery is full, and there is no so-called trickle charging for the nickel electric charge. That is, if your lithium-ion battery is full, it is also white charge.

And we can't guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and quality, so your battery will be in dangerous edges. This is another reason why us oppose long charging. For some mobile phones, the charger is charged more than a certain period of time, if the charge is not removed, the system not only does not stop charging, but also starts the discharge - charging cycle.

Perhaps the manufacturer of this practice has its own purpose, but it is clear that the battery and mobile phone / charger are unfavorable. At the same time, long-term charging is long, often in the night, while in my country's power grid, the voltage in many parts is relatively high, and the fluctuations are large. As mentioned earlier, the lithium-ion battery is very delicate, it is much more resistant to the fluctuations in the charge and discharge, so this also brings additional dangers.

In addition, another aspect of not ignored is that the lithium ion battery is also not suitable for over-discharge, and the over-discharge is also very disadvantageous to the lithium-ion battery. 2. When should we start charging in normal use? We can often see this, because the number of charge and discharge is limited, so the electric battery should be charged as light as possible.

But I found a experimental table for lithium-ion battery charging cycles, and the data about cycle life is listed below: Circulation Life (10% DOD):> 1000 cycle life (100% DOD):> 200 times where DOD is discharge Depth English abbreviation. As can be seen from the table, the number of chargeable times and the discharge depth, the cycle life of 10% DOD is much longer than 100% DOD. Of course, if it is equally contrary to the relative total capacity of actual charging: 10% * 1000 = 100, 100% * 200 = 200, the latter's complete charge and discharge is still better, but the previous netizen's saying should be amended: in normal In the case, you should reserve the principle of recharging the remaining electricity of the battery, but if your battery is expected to stick to the whole day, you should start charging in time, of course, if you want to back Charger to the office is also.

And when you want to charge, it is expected that it is expected to lead to an important event that will lead to busy communication. It is 0.X, and often this X will be small.

The principle of battery remaining electricity is not to be tired to extreme. One statement on the same flow of long charging is the same, that is, try to use the battery's battery, it is best to automatically shut down. This practice is actually just the practice of nickel battery, the purpose is to prevent memory effects, unfortunately, it is also circulating on lithium-ion batteries.

Some people have appeared after the warning of the battery battery is too low, still not charging the use of automatic shutdown examples. Result The mobile phone in this example has no response in the later charging and boot, and has to send customer service inspection. This is actually because the battery causes the voltage to be too low due to excessive discharge, so that there is no normal charging and power-on conditions.

3, the correct approach to the lithium-ion battery phone, I am the most important tips for the charge and discharge problem in the use of lithium-ion battery mobile phones are: 1 According to the standard time and program, even the first three times should be done; 2 When the phone is too low, it should be started to start charging in time; 3 The activation of the lithium ion battery is not a special method, and the lithium ion battery will naturally activate in the normal use of the phone. If you insist on the three 12-hour long charging activation methods to be used in the first three times, it will not actually have effects. Therefore, all the practices that pursue 12 hours of super long charging and use lithium-ion battery mobile phone automatic shutdown are incorrect.

If you used to do it according to the wrong statement, please correct it in time, maybe it is not too late. Of course, in the case where the mobile phone and the charger itself protects and controls the quality of the circuit, the protection of the lithium-ion battery is still quite guaranteed. Therefore, the understanding of the charging rules is the focus.

In some cases, some concessions can be made. For example, if you find that the phone must be charged before you go to bed, you can start charging before going to bed. The key to the problem is what you should learn about the correct approach, and don't deliberately do it according to the wrong statement.

4. How to use it to maximize the efficacy of the battery, extend the battery life? Misunderstanding, first use battery, the first three times to charge 12 hours, this is completely unnecessary. Because the current laptop has a complete power management circuit and the charging management system.

When the battery reaches saturation, the control circuit will automatically switch to the open state, so as long as it is full, it is not, the longer you can use it. of. Misunderstanding, in order to prevent memory effects, it is necessary to discharge the battery before charging, and it is harmful.

Because of practice proves: The battery's depth discharge will never reduce the battery life, it is recommended to charge when the battery is 10% left and right. Of course, when there is still more than 30% of the electricity, it is best not to charge, because the memory effect does exist. Misunderstanding three, when the AC is inserted, take the battery to prevent repeated charge of discharge, it is: No! Of course, you can take the natural discharge of the lithium-ion battery to refute me, saying that after the battery is naturally discharged, if there is power access There will be repeated charge and discharge, reducing the battery life of the battery.

And I have the reason why I don't have to use this answer: 1. Now the power control circuit of the notebook has designed this characteristic: It will be charged when the battery is 90% or 95%, and the capacity is reached by natural discharge. Time is 2 weeks to a month, when battery idle does not need to be fully charged and discharge to maintain the battery, this time you should care about the battery should exercise instead of being charged after it.

2. Even if the battery is unfortunately charged, the loss will not drop much more than the battery caused by the battery. 3.

Your data is much more precious than your battery or even your notebook. Suddenly, the power cut is not only harm to your notebook, but the data that cannot be saved is not regret. 4, while connecting the DC power supply without removing the battery without any damage, because the battery will not accept any electric injection after the battery is filled, the power will all direct all the power supply system directly to the notebook.

But when the notebook is running at high speed, it is best to remove the battery during the internal overheat, otherwise it is harmful. Misunderstanding 4, long-term storage battery to be filled with electric or put on the light, if you have long used AC power supplies for a long time, you can also remove the battery, place it to reduce the number of charge and discharge. However, pay attention to the long-term preservation of the light to make the battery lose activity, and even lead to control circuit protection self-locking and can no longer use.

Full of electric long-term preservation will bring secure hidden dangers, the most ideal storage method is to use power to 40% The left and right then saved in a cool dry place, about 20 degrees Celsius is ideal for preservation temperature. Of course, it is best to take the battery once every month, which can guarantee good storage status, and do not make the power loss and damage the battery. See the following table: (percentage for the percentage of saturation state relative to the initial value) storage temperature 40% charging state 100% charge state 0 degree 98% (one year later) 94% (one year later) 96% (one year) After 80% (a year later) 40 degrees 85% (one year later) 65% (one year later) 60 degrees 75% (one year later) 60% (3 months later) extending the working hours of the laptop battery Measures to lower the screen brightness to make good use of standby, sleep, etc.

Open the cpuspeedstep feature, which can greatly extend the working time of the battery: The SpeedSteP function of the CPU is booted by default in the BIOS. When using the battery, the CPU will automatically down, to achieve energy saving purposes. When using the battery, try to close the wireless, Bluetooth and the infrared port as possible.

Remove peripherals that do not need to be used and prevent large 3D programs, games, etc. to reduce unnecessary battery consumption. .
