Misunderstanding analysis and precautions of battery charger charging method


At present, batteries are widely used in mobile phones and other products. However, there are several misunderstandings in the charging methods, especially the saying that the first three charges take more than 12 hours is unpopular. However, is this kind of communication accurate? Let's take you to know.

At present, batteries are widely used in mobile phones and other products. However, there are several misunderstandings in the charging methods, especially the saying that the first three charges take more than 12 hours is unpopular. However, is this kind of communication accurate? Let's take you to know.
1、Charging method of battery charger
The most popular way to deal with the charging of new batteries is to charge for more than 12 hours to activate the battery. "But is this kind of saying accurate or wrong? The answer is wrong.
The first reason: for batteries, both overdischarge and overcharge will cause great damage to the batteries. It is best to charge the batteries according to the standard time and method, and remember not to charge for more than 12 hours.
The second reason is that the battery will stop charging when it is fully charged, but if it is placed on the charger continuously, it can present discharge charging cycle, the characteristics of the battery charging and discharging protection circuit can change, and the battery is at the edge of risk.
2、How to charge the battery charger
There are many different opinions on how to charge the battery when it is used abnormally. Some friends say that "it is necessary to turn off the battery on its own initiative and recharge it when there is no electricity left", but some friends show that they "charge as you use it".
The first reason is that the life of lithium battery is 300 ~ 500 charging cycles. Assuming that the power supplied by a complete discharge is 1q, the lithium battery can supply 300q ~ 500q power regardless of the reduction of power in each charging cycle in the future. If 1 / 2 charge is used each time, it can charge 600-1000 times; if 1 / 3 charge point is used each time, it can charge 900-1500 times; if random charge is used, the number of times is variable. The battery life is related to the total charge quantity of the battery, but it is related to the charging times.
The second reason: in fact, shallow discharge and shallow charge is more beneficial to the battery. As long as the power module of the product calibrates the battery, there is a need for deep discharge and deep charge. Therefore, in the normal use process, you can not stick to the use of photoelectric recharging, you can charge with the use, convenience first.
3、Battery charging method -- precautions
Note 1: avoid too high temperature when charging
If the temperature during charging is higher than the specified operating temperature (35 ℃), the battery power will be reduced, that is, the power supply time will be prolonged when the battery is fully charged, which will damage the battery quality and reduce the battery life.
Note 2: avoid too low temperature when charging
If the battery is at a low temperature (below 4 ℃) during charging, the power of the battery will be reduced, or even the battery will not be charged. However, the situation is different from that at a low temperature, and the battery will not be destroyed forever. When the temperature is reduced to a proper level, the battery power will return to the previous situation.
Note 3: often use
It is often used to keep the electrons in the battery active, which is conducive to the extension of its life. If you don't use it often, remember to realize a charging cycle for the battery every month, that is, deep discharge and deep charge once.
