How long is the service life of 26650 lithium-ion battery and precautions for its use

　　How many times can the 26,650 lithium battery be charged? It is believed that this is a long perplexing thing. In fact, the charging cycle of a typical 26650 lithium battery is 300~500. Assuming that the power provided by a full discharge is 1000, if the power reduction after each charging cycle is not considered, the lithium battery can provide or supplement a total of 300q~500q of power during its service life. 26650 lithium-ion battery charging In short, no matter how it is charged, the total power will increase by 300q-500q, which is constant. Therefore, we can also understand that the service life of the lithium ion battery is related to the total charge capacity of the battery, but not to the number of charges. Deep discharge and deep charge, shallow discharge and shallow charge have little effect on the life of lithium battery. Well, when some MP3/mp4 manufacturers publicized, they said that a certain type of MP3 uses a powerful lithium-ion battery, which can be charged more than 1500 times. This is pure ignorance of consumers. So what should we pay attention to when using 26,650 lithium battery? Now let's follow the new energy manufacturers to find out.

　　1、 Precautions for use of 26650 lithium-ion battery

　　(1) Prevent charging at excessive temperature. If the 26650 lithium-ion battery is used in an environment higher than the specified operating temperature (i.e. higher than 35 ℃), the power of the battery will continue to decrease, that is, the power supply time of the battery will not be as long as usual. If the device is charged at this temperature, the damage to the battery will be greater

　　(2) Prevent charging when the temperature is too low. If the lithium battery is used in a low temperature environment, that is, lower than 4C, the service life of the 26650 lithium ion battery will also be shortened, and the original lithium battery of some mobile phones cannot even be charged in a low temperature environment

　　(3) Regular use of life lies in exercise. If you want to maximize the efficiency of the 26650 lithium-ion battery, you should always use it to keep the electrons in the lithium-ion battery in a flowing state. If you do not use the lithium battery frequently, please remember to complete the charging cycle of the lithium battery every month and calibrate the power supply, that is, deep discharge and deep charge.
