How to charge the battery?


In the use of lithium batteries, we should pay attention to that when the battery is placed for a period of time, it will go to sleep state. At that time, the capacity is lower than the normal value, and the use time will also be shortened. But the lithium battery is easy to activate, and the battery can be activated by 3 - 5 normal charging and discharging cycles to restore the normal capacity. Because of the characteristics of the lithium battery itself, it has decided that it has almost no memory effect. Therefore, the new lithium battery in the user's cell phone does not require special methods and equipment during the activation process. Not only in theory, but in my own practice, it is the best to use standard methods to recharge this "natural activation" approach from the beginning.


For the "activation" of lithium batteries, many of the claims are that the charge time must exceed 12 hours, repeated three times, in order to activate the battery. The term "charge for the first three times for more than 12 hours" is obviously a continuation of nickel batteries, such as nickel and nickel, and nickel hydrogen. So this statement can be said to be misunderstood at the beginning. There was a big difference between the charging and discharging characteristics of lithium batteries and nickel battery, very clear and can tell you, I have had access to all serious formal technical data are emphasized and charge off will discharge lithium batteries, especially liquid lithium ion battery causing great harm. So it's best to charge the charge according to standard time and standard methods, especially if you don't take over 12 hours of super long charge. Usually, the charging method introduced in the handset instructions is the standard charging method suitable for the mobile phone.


In addition, the battery or battery charger of lithium battery will stop automatically after the battery is filled. There is no so-called "trickle charge" that the nickel electric charger calls for 10 hours. That is to say, if your lithium battery is full, put it on the charger. None of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality is guaranteed. So your battery will linger on the dangerous edge for a long time. This is another reason why we are opposed to long charging.


In addition, when some cell phones are charged for a certain time, if they do not pick up the charger, the system will not only stop charging, but also start the discharge charging cycle. Perhaps the manufacturer of this practice has its own purpose, but it is clear that the battery and the life of the cell phone / charger are disadvantageous. At the same time, long charging takes a long time, and often needs to be carried out at night. In the case of China's power grid, the voltage at night is quite high and fluctuating in many places. As already mentioned, the lithium battery is very delicate, its ability than nickel in the charge discharge resistant fluctuation is much worse, so this brings additional risk.


In addition, another aspect that can not be ignored is that lithium batteries are also not suitable for overdischarge, and overdischarge is also very bad for lithium batteries. This leads to the following questions.
