【The right way】
In the use of lithium batteries should be noted that although the battery factory are activated, but after a period of time into the dormant state, then the capacity in the virtual state. But the lithium battery is easy to activate, as long as after about 3 times the normal charge and discharge cycle can activate the battery, restore normal capacity. Due to the characteristics of the lithium battery itself, it is almost no memory effect. So the user's mobile phone in the new lithium battery in the activation process, is no need for special methods and equipment. Not only theoretically the case, from my own practice point of view, from the beginning to use 3 times the standard method of charging this "natural activation" approach is the best.
【misinformation】
For the lithium battery "activation" problem, many of the argument is: the charging time must be more than 12 hours, repeated three times in order to activate the battery. This "the first three charges to charge more than 12 hours" argument, obviously from the nickel batteries (such as nickel and cadmium and nickel hydrogen) continued to say. So this argument can be said that the beginning is misleading. Lithium batteries and nickel batteries charge and discharge characteristics of a very big difference, and can be very clear to tell you that I have read all the serious technical information are stressed overcharge and over discharge will be lithium batteries, especially liquid lithium Ion batteries cause great damage. So the best charge in accordance with standard time and standard method of charging, in particular, do not carry out more than 12 hours of long charge. Usually, the phone instructions on the charging method, is suitable for the phone's standard charging method.
【Battery killer - universal charge】
Universal charge just when the "universal" characteristics and ultra-low prices immediately make it popular north and south, not only dealers favor, consumers are more love. Universal charge to the dealer and machine friends have brought great convenience.
But soon, we found that the use of universal charge, the battery was inflated more than a few times.
The reason, the root of the problem or out of the universal "universal" requirements, because it should be applied to any battery, must be included in the charging voltage range of all possible batteries, then there will be "overcharge" "Full of dissatisfaction", "inflated" or even explode and so on all kinds of problems.
【Charge principle analysis】
(1) lithium battery will automatically stop after filling, but the phone will continue to power consumption, a little power consumption after the phone and immediately charge, this is full of stop - consumption of electricity and charge cycle called "trickle" charge , This state is most likely to inflate the battery. This is the first reason we are opposed to long charging
(2) a long time plug the charger, can not guarantee the battery charge and discharge protection circuit characteristics never change and quality foolproof, so your battery will be a long time in the dangerous edge of the wandering. This is another reason we oppose the long charge.
(3) At the same time, long charging takes a long time, often need to be carried out at night, and the situation in China's power grid, many places the night voltage is relatively high, and volatile. So this brings additional risk.
【When should you start charging in normal use?】
In our forum, you can often see this argument, because the number of charge and discharge is limited, so the phone battery should be used as much as possible to recharge the battery. But I found a test on the charge-discharge cycle of lithium-ion battery, the data on the cycle life is listed as follows:
Cycle life (10% DOD):> 1000 times
Cycle life (100% DOD):> 200 times
Where DOD is the abbreviation of the depth of discharge. As can be seen from the table, the number of chargeable and discharge depth, 10% DOD cycle life than 100% DOD to be much longer. Of course, if the equivalent of the actual capacity of the actual charge: 10% * 1000 = 100,100% * 200 = 200, the latter fully charge and discharge or to be better, but in front of that statement to do some amendments: In case you should keep the battery in accordance with the principle of the remaining battery charge and then charge the charge, but if your battery is expected in your second day can not adhere to the whole day, it should start charging in a timely manner, of course, if you are willing to back The charger to the office and when the other.
And you need to charge to cope with the expected arrival of important events that will lead to busy traffic, even when the battery has a lot of excess electricity, then you just charge in advance, because you did not really lose the "1" times the charge cycle life , That is, "0.x" times only, and often this x will be very small.
The battery remaining power out of the principle of reloading is not to you to the extreme. And long charge as widely circulated a saying, is "as far as possible the battery life of mobile phones, it is best to use automatic shutdown." This practice is only the practice of nickel batteries, the purpose is to avoid the memory effect occurs, unfortunately it is also circulating in the lithium battery today. Some people because the phone battery is too low after the warning appears, still do not charge to continue to use the automatic shutdown has been used examples. The results of this example in the phone in the subsequent charge and boot are no response, had to send customer service overhaul. This is actually because the battery due to excessive discharge caused by the voltage is too low, so do not have the normal charge and boot conditions caused.
