Guide: In the use of a lithium battery, it should be noted that the battery will enter the sleep state after a period of time. At this time, the capacity is below normal, and the usage time is also shortened. However, the lithium battery is easy to activate, as long as it passes through 3-5 normal charge and discharge cycles, the battery can be activated, and normal capacity is restored.

Due to the characteristics of the lithium battery itself, it determines that there is almost no memory effect. It should be noted in the use of lithium batteries that the battery is placed in a sleep state. At this time, the capacity is below the normal value, and the usage time is also shortened.

However, the lithium battery is easy to activate, as long as it passes through 3-5 normal charge and discharge cycles, the battery can be activated, and normal capacity is restored. Due to the characteristics of the lithium battery itself, it determines that there is almost no memory effect. Therefore, the new lithium battery in the user's phone is in the process of activation, it is not required for special methods and equipment.

Not only theory is theory, from my own practice, from the beginning, I use standard methods to charge this "natural activation" mode is the best. The correct lithium battery activation and charge and discharge method For the "activation" problem of lithium 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 12 hours more" said that it is obvious to continuing 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 lithium batteries and nickel batteries can be very different, and you can tell you very clearly. All serious formal technical materials I have reviewed emphasize that they will overcharge and over-discharge will for lithium 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. Typically, the charging method described in the instruction manual is the standard charging method.

At the same time, long charging takes a long time, often needs to be carried out at 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 battery is very delicate, it is much more resistant to the fluctuations in charge and discharge, so this is a dangerous danger. In addition, another aspect of not ignored is that lithium batteries are also not suitable for over-discharge, and over-discharge is also very disadvantageous to lithium batteries.

Tool / raw material lithium battery, nickel-hydrogen battery, lithium battery charger, nickel-hydrogen battery charger step / method should start the charging forum whenever you can see this, because the number of charge and discharge is limited, So you should charge the battery as much as possible with light. But I found an experimental table for lithium-ion battery charging cycles, and the data on the loop life is listed as follows: 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 equivalent to the relative total capacity of the actual charging: 10% * 1000 = 100, 100% * 200 = 200, the latter 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 charging according to the battery remaining battery, but if your battery is not possible to insist on two hours in the second day, you should start charging in time, of course, if you are willing Carrying up the charger to the office is another matter. When you need to charge to cope with it is expected that it is inconvenient or conditionally not allowed to charge, even when there is a lot of power, then you only charge in advance, because you don't really lose "1" times charging cycle life, that is, " 0.X "times, 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 as long charging, "Try to use the battery's electricity, it is best to use automatic shutdown". This practice is actually just the practice of nickel battery, the purpose is to avoid memory effects, unfortunately, it is also circulating it on the lithium battery.

Since the battery causes the battery due to excessive discharge, it does not have normal charging and power-on conditions. The correct approach to the lithium battery is attributed. The most important tips for the charge and discharge problem in the use of lithium batteries are: 1, charging according to the standard time and program, even the top three times; 2, when there is an electric quantity When you are too low, you should start charging in time; 3.

Activation of lithium batteries does not require a special method, in normal use, lithium batteries will naturally. If you insist on "the first three 12-hour long charging activation" method, it will not have effects. Therefore, all pursuing 12 to 16 hours of ultra-long charging and use lithium batteries to automatic shutdown, are wrong.

If you have done according to the wrong statement, please correct it in time, maybe it is not too late. Note that the original charger itself protects and controls the quality of the control circuit, there is still a considerable guarantee of the protection of lithium batteries. Therefore, the understanding of the charging rules is the focus.

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