Detailed explanation of correct charging method of lithium ion battery -Lithium - Ion Battery Equipment
1. How to charge the new battery
In the use of lithium-ion batteries, it should be noted that the battery will enter the sleep state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time will also be shortened. However, lithium-ion batteries are easy to activate. They can be activated after 3-5 normal charge-discharge cycles to restore normal capacity. Because of the characteristics of lithium-ion battery itself, it has almost no memory effect.
As for the activation of lithium-ion batteries, many people say that the charging time must be more than 12 hours and repeated three times to activate the battery. The statement that the first three charges need more than 12 hours is clearly a continuation of nickel batteries (such as nickel cadmium and nickel hydrogen). So this statement can be said to be misinterpreted at the beginning. The charge and discharge characteristics of lithium-ion batteries and nickel batteries are very different, and I can tell you very clearly that all the serious official technical data I have reviewed emphasize that overcharge and overcharge will cause great damage to lithium-ion batteries, especially liquid lithium-ion batteries. Therefore, it is better to charge according to the standard time and standard method, especially do not charge for more than 12 hours. Generally, the charging method explained in the mobile phone manual is the standard charging method suitable for the mobile phone.(Lithium - Ion Battery Equipment)
In addition, the mobile phone or charger of lithium-ion battery will automatically stop charging after the battery overflows, and there is no so-called trickle charging of nickel battery charger for more than 10 hours. That is to say, if your lithium-ion battery is overflowing, it will be charged in vain if you put it on the charger. However, none of us can guarantee that the characteristics of the charge and discharge protection circuit of the battery will never change and the quality will be guaranteed, so your battery will be at the edge of danger for a long time. This is another reason why we oppose long-term charging.
In addition, for some mobile phones, if the charger is not removed after charging for a certain time, the system will not only stop charging, but also start the discharge-charge cycle. Maybe the manufacturer of this method has its own purpose, but it is obviously detrimental to the life of battery and mobile phone/charger. At the same time, long-term charging takes a long time, and often takes place at night. According to the situation of China's power grid, the voltage at night in many places is relatively high and fluctuates greatly. As we have said before, lithium-ion batteries are very delicate. They are much less resistant to fluctuations in charge and discharge than nickel batteries, which brings additional risks.
In addition, another aspect that cannot be ignored is that lithium-ion batteries are also not suitable for over-discharge, which is also very unfavorable for lithium-ion batteries. This leads to the following questions.
2. When to start charging in normal use
In our forum, we can often see this statement. Because the number of charging and discharging is limited, we should recharge the cell phone battery as much as possible. But I'm looking
According to a test table about the charge and discharge cycle of lithium-ion batteries, the data about the cycle life are listed as follows:
To sum up, my most important tip about the charging and discharging of lithium-ion battery mobile phones in use is:
A Charge according to the standard time and procedure, even the first three times;
B When there is a prompt that the battery of the mobile phone is too low, try to start charging as soon as possible;
C. There is no special way to activate the lithium-ion battery. The lithium-ion battery will be activated naturally during normal use of the mobile phone. If you insist on using the first three 12-hour long charging activation methods, it will not work.
Therefore, it is wrong to pursue 12 hours of ultra-long charging and to use lithium ion battery phones for automatic shutdown. If you used to do it in the wrong way,
Please correct it in time. It may not be too late.
Of course, the protection of lithium-ion batteries is quite guaranteed under the condition that the protection and control circuit of mobile phones and chargers are of good quality. Therefore, the understanding of charging rules is the key point. In some cases, it is also possible to make some compromises. For example, if you find that your mobile phone must be charged before you go to bed at night, you can also start charging before you go to bed. The key is that you should understand what is right and don't deliberately follow the wrong way.
