What are the issues that must be paid attention to when using 26650 lithium batteries

The 26650 lithium battery refers to a cylindrical steel shell lithium battery cell with a diameter of 26 mm and a height of 65 mm. It is the same type of rechargeable battery as the 18650 lithium battery, and its knowledge level is different. The service life of 26650 lithium battery is generally 300-500 battery charging cycle time. Assuming that the output power shown by the complete charge and discharge is 1Q, if the output power reduction after each battery charging cycle system is not taken into account, the lithium battery can show or fill the output power of 300Q-500Q within its service life. Therefore, if you use 1/2 charge each time, you can charge 600-1000 times; if you use 1/3 charge each time, you can charge 900-1500 times. By analogy, if the charging standard is arbitrary, the frequency is uncertain. In fact, shallow charging and discharging shallow battery charging is more beneficial to lithium batteries. The commercial switching power supply is only required to charge the deep charge and discharge battery when it is calibrated for lithium batteries. Therefore, products that use lithium as the driving force need not be limited to the production process, everything is convenient, and the battery can be charged anytime, anywhere, without worrying about jeopardizing the service life. All in all, no matter how charged, the total output power of 300Q-500Q is stable. Therefore, everyone can also know that the service life of a lithium battery is related to the total battery charging capacity of the rechargeable battery, and is not related to the battery charging frequency. There is not much difference between deep charge and discharge and shallow charge and discharge on the life span of lithium batteries. What are the issues that must be paid attention to when using 26650 lithium batteries? 1. Beware of low temperature battery charging. If the lithium battery is used in an ultra-low temperature natural environment, that is, below 4°C, the use time of the 26650 lithium battery will be reduced. The original lithium battery on some mobile phones cannot be charged even in a low-temperature natural environment. But don't worry too much, this is only a temporary situation, and it is not the same as the use in a high-temperature natural environment. Once the temperature rises, the molecular structure in the rechargeable battery will be heated and immediately restored to the previous output power. 2. Beware of high temperature battery charging. If the 26650 lithium battery is used in a natural environment above the required operating temperature, that is, above 35°C, the battery power will continue to decrease, that is, the power supply system time of the rechargeable battery will not be as long as usual. If the machine and equipment must be charged at that temperature, the damage to the rechargeable battery will be even greater. Even if the rechargeable battery is stored in a high-temperature natural environment, it is difficult to guard against the relative harm to the quality of the rechargeable battery. Therefore, maintaining a stable operating temperature as much as possible is a good way to increase the life of lithium batteries. 3. Frequent use In order to fully utilize the greater high efficiency of the 26650 lithium battery, it is necessary to use it frequently, so that the electronic devices in the lithium battery are in a fluid state from beginning to end. If you don't use lithium batteries frequently, please remember to charge the lithium batteries for one battery charge cycle every month, and do a power calibration, that is, deep charge and discharge and deep battery charge.
