3.7 volt 18650 lithium battery

　　How to use 26650 lithium battery reasonably

　　The service life of 26650 lithium battery is generally 300-500 battery charging cycles. Assuming that a complete charge and discharge provides 1Q of power consumption, if the reduction in power consumption after each battery charging cycle is not taken into account, the lithium battery can provide or supplement 300Q-500Q of electromagnetic energy during its service life. As we all know, if you charge 1/2 every time, then it can be charged 600-1000 times; if you charge 1/3 every time, then it can be charged 900-1500 times. In this way, if any battery is charged, the frequency is uncertain.

　　In fact, shallow discharge and shallow charging are more beneficial to lithium batteries. Deep discharge and deep charging are only necessary after the product's power supply has calibrated the lithium battery. Therefore, products using lithium battery power systems do not need to be limited to processing technology, everything is focused on convenience, and they can be charged at any time without worrying about affecting the service life.

　　Generally speaking, no matter how the battery is charged, the power of 300-500Q with full fuel is stable. Therefore, we can also understand that the service life of lithium batteries is related to the total charging capacity of the battery and has nothing to do with the frequency of charging. In terms of the service life of lithium batteries, there is not much difference between deep discharge and deep charging and shallow discharge and shallow charging. Therefore, some MP3 manufacturers publicize and say, "A certain model of MP3 uses strong lithium batteries, and the battery can be charged more than 1,500 times." This is completely deceiving consumers.

　　1. Prevent battery charging at too low temperatures.

　　Similarly, if the lithium battery is used in ultra-low temperature environments below 4°C, the service life of the 26650 lithium battery will also be shortened. Some genuine lithium batteries in mobile phones cannot even be charged in ultra-low temperature environments. But don’t worry too much. This is only a temporary situation. Unlike when used in a high-temperature environment, once the temperature rises and the molecular structure in the battery is heated, it will immediately respond to the original power consumption.

　　2. Prevent battery charging at excessive temperatures;

　　If the 26650 lithium battery is used to operate at the required operating temperature above 35°C, the power consumption of the battery will continue to decrease, that is, the power supply time of the battery will not be as long as in the past. If the equipment battery is charged at this temperature, the battery will suffer greater damage. Even storing the battery in a hot environment will inevitably cause relative damage to the quality of the battery. Therefore, trying to maintain a moderate operating temperature is a very good way to increase the service life of lithium batteries.

　　3. Apply frequently.

　　Life is about fitness. In order to make the 26650 lithium battery achieve greater efficiency, it must be used frequently to keep the electronics in the lithium battery fluid. If the lithium battery is used infrequently, you must remember to perform a charging cycle every month and perform a power calibration, that is, deep discharge and deep charging.
