The service life of 26650 lithium-ion battery is generally within 300-500 battery charging cycle time. Assuming that a complete charge and discharge shows 1Q of power consumption, if the reduction in power consumption after each battery charging cycle time is not taken into account, the lithium-ion battery can show or fill up 300Q-500Q of electromagnetic energy during its service life. Everyone knows that if every time you charge 1/2, then it can charge 600-1000 times; if every time you charge 1/3, then it can charge 900-1500 times. In this way, if any battery is charged, the frequency is uncertain.

In fact, shallow charging and shallow charging are more beneficial to lithium-ion batteries, and deep charging and deep charging are only necessary after the commercial switching power supply is calibrated for lithium-ion batteries. Therefore, products that use lithium-ion battery power supply systems do not need to be limited to the processing technology, and everything is led by convenience, and the battery is charged anytime and anywhere, and there is no need to worry about jeopardizing the service life.energy storage battery types.

In general, no matter how the battery is charged, the power of 300-500Q with full fuel is all stable. Therefore, everyone can also understand 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. In terms of the service life of lithium-ion batteries, there is not much difference between deep discharge and shallow charge. Therefore, some MP3 manufacturers publicize and plan to say, “The MP3 of a certain model specification uses a strong lithium battery, and the battery charging frequency exceeds 1500 times.” It is completely deceiving the ignorance of consumers.

1. Prevent the battery from charging at too low temperature.

Similarly, if the lithium-ion battery is used in an ultra-low temperature natural environment below 4°C, the use time of the 26650 lithium battery will also be reduced. The genuine lithium-ion battery on some mobile phones can even be charged in an ultra-low temperature natural environment. However, there is no need to worry too much. This is only a temporary situation, unlike the application in a high-temperature natural environment. Once the temperature rises, the molecular structure in the rechargeable battery will immediately respond to the original power consumption.

2. Prevent the battery from charging at too high temperature;

If the 26650 lithium battery is used to work at the required operating temperature above 35°C, the power consumption of the rechargeable battery will continue to decrease, that is, the power supply system time of the rechargeable battery will not be as long as in the past. If the machine equipment battery is recharged under such temperature, the rechargeable battery will suffer more damage. Even storing the rechargeable battery in a relatively hot natural environment will cause relative harm to the quality of the rechargeable battery, which is difficult to prevent. Therefore, maintaining a moderate operating temperature as much as possible is a very good way to increase the service life of lithium-ion batteries.

3. Apply frequently.

Life is fitness exercise. In order to better enable the 26650 lithium battery to give full play to greater efficiency, it must be used frequently to make the electronic devices in the lithium-ion battery continue to maintain fluidity. If the lithium-ion battery is not used frequently, you must remember to carry out a battery charging cycle time every month and carry out a battery calibration, that is, deep discharge and deep charge.
