A: how many cycle lithium batteries can be used with normal?

Source: 2020 - 03 - 30 14:08 hits: lithium battery can use how long? A: how many cycle you can usually use? What factors affect the life? Refers to the capacity of the battery charging cycle from full to empty, and then from empty to full, this is different from charge. Lithium-ion batteries used in the first day, for example, half of the battery, then charge. If the next day or so, with half of the charge, a total of two charge drops, it can only be classified as a charge cycle, not two. Therefore, may take a few time charge to complete a cycle. Each cycle, the capacity of the battery will reduce a little. However, the power of small size, high quality batteries in many times after charging still can maintain 80% of the original capacity, many lithium-ion products in two to three years later still can continue to use. The lithium battery and, of course, life is still need to be replaced. 500 times, refers to the manufacturer in a stable discharge depth ( Such as 80%) 625 times or so after the number of charging, charging cycle of 500 times. ( 80% * 625 = 500) ( Ignore the lithium battery capacity to reduce etc. ) But due to various effects of real life, especially when charging discharge depth is not stable, so '500 times charging cycles can only be used as a reference battery life. Right way: end of the service life of lithium battery and charging cycle times, have no direct relationship with the charging times. , in a nutshell, lithium batteries, for example, use half of the charge on the first day, and then charging. If the next day or so, with half of the charge, a total of two charge drops, it can only be classified as a charge cycle, not two. Therefore, may take a few time charge to complete a cycle. Every time you complete a charge cycle, charging will reduce a little. But small cuts in the,, after many cycles remained 80% of the original high quality battery capacity, that is why many lithium-ion products in two or three years later still can continue to use. Of course, when the lithium battery life rose, it will need to be replaced. Lithium battery service life of the general is 300 ~ 500 times charging cycle. Assumption completely discharge power is to ask, if a reduction in the number of power in the future of every charge cycle does not consider, a total of 300 Q - 500 Q of electricity can provide or make up a life of lithium. Every time so we know that if we use 1/2 charge, we can charge 600 - 1000 times; If each time with a third of the power, you can charge 900 ~ 1500 times. For example, if a random charging, variable number. In a word, no matter how the charging, there are 300 q and 500 q battery into this point is stable. Therefore, we can also understand, lithium battery life is associated with the total power of the battery, has nothing to do with how much power. Deep discharge and shallow discharge no difference influence on the service life of lithium. Shallow discharge light charging of lithium battery, in fact, much better, only in the power supply module of product to the lithium battery on time to do it, have a deep discharge charge is necessary. Therefore, the use of lithium power supply in the process of products do not need to be jammed, everything is for the first, at any time the charging, don't worry about life. If the use of lithium temperature more than 35 ℃, the battery power will decrease, which means that the battery life won't be as long as usual. If you have to recharge your device under this temperature, damage will be bigger. Even if the battery is stored in high temperature environment, the battery quality also would inevitably suffer. Therefore, to keep the appropriate operating temperature is a good way to prolong the service life of the lithium battery. If in the low temperature environment, namely the below 4 ℃ using lithium battery, also found that using time of the battery, some mobile phone original lithium battery charging even in low temperature environment. But don't worry too much about, this is just a temporary situation, like not to be used in high temperature, once the temperature, the battery will be heated, the molecules in restoring the original battery. In order to make full use of lithium ion battery, they usually need to keep the electron flow. If you don't often use lithium battery, please be sure to remember every month for lithium battery to the end of a charge cycle for a power calibration, which deeply to recharge.
