The life of lithium iron phosphate battery is 500 times; 500 times of charge and discharge. After this number, the battery will die. In order to extend the life of the battery, many friends charge it every time when the battery is completely exhausted. Does this really prolong the life of the battery? The answer is negative. The life of lithium iron phosphate batteries is 500 times; it does not refer to the number of charges, but the cycle of charge and discharge. A charging cycle symbolizes the process of all the power of the battery from full to empty, and then from empty to full, which is not the same as a single charge. For example, a lithium battery uses only half of the electricity in the sky, and then it is fully charged. If it is still the same the next day, that is, it will be charged with half and charged twice in total, it can only be counted as one charging cycle, not two.

     Therefore, it usually takes a number of charges to achieve a cycle. Every time a charging cycle is achieved, the battery capacity will be reduced a little. However, the amount of electricity is very small. After repeated cycles of charging, the high-quality battery will still save 80% of the original capacity. Many lithium-powered products will still be used as usual after two or three years.

     Of course, the lithium battery life still needs to be replaced after it reaches its life. The so-called 500 times means that the manufacturer has achieved about 625 recharge times at a constant discharge depth, reaching 500 charging cycles. Because of the various effects of real life, especially the discharge depth during charging, is not constant, 500 charging cycles; can only be used as a reference battery life. Once a day, if you use it once, it will be counted as a round; if you fill half, if you use half, it will be counted as half a cycle. Therefore, according to the correct use of the battery, the electric vehicle is used every day, and the lithium iron phosphate battery life is at least three years old.

    We often have lithium iron phosphate batteries that are recharged after they are exhausted; or lithium iron phosphate batteries must be charged continuously after they are full, and they must be charged for 12 hours. However, if you make the lithium iron phosphate battery charge or discharge moderately, it will not only not extend the life of the lithium iron phosphate battery in electric vehicles, but also shorten it.
