How to properly charge a lithium battery to maintain its life

When computer city sales staffs answer the questions about lithium battery life, they often say that "it can charge one hundred times." In fact, the correct expression is "lithium battery cycle life is related to charging cycle times, rather than the number of charge times."

As everybody knows, lithium battery is one of the advantages that can be convenient time for at any time lithium ion batteries after charging, rather than to have to electric light to refill. So, what is charge cycle? A charge cycle means that all the power battery by full use empty, again by the empty into the full process, this is not the same as to charge. Speak a little bit more simple, 600 mAh lithium batteries, you first by 0 mAh 400 mAh, filling with ah ah with N ma; And then you charge the 150 mAh, N, with mAh; Finally, 100 mAh, when the last charge to 50 ma, a charge the battery cycle.(400 + 150 + 50 = 600)

A li-ion battery on the first day is only half of the battery, then charge for it. If so, the next day with half of the charge, the total charges down, it can only be counted as a charge cycle, instead of two. Often, therefore, may be charging after several times to complete a cycle. Each completed a charge cycle, power will reduce a little. This is why a lot of people who use lithium battery cell phone will often say: "this broken phone, just buy back can use 4 days, now charge used only three and a half days". The power decrease rate is very small, however, the high quality of battery charge cycle for many times, still will retain 80% of the original electricity, a lot of lithium electric power products after two or three years later still use as usual. Li-ion battery life eventually needs replacing.

The life of the lithium electricity generally is 300-500 charge cycles. If a completely discharge to provide power for 1 q, if you don't consider charging each cycle after power decreases, the lithium electricity within its life can provide or replenish a total of 300 q - 500 q of power. From this we know that, if every time filled with 1/2, translates to 600-1000 times; A third charge, every time. If you can charge 900-1500 times by analogy, if the random charging, the number of times. In a word, no matter how to charge, added into a total of 300 q - 500 q power that is constant. So, we can understand like this: the lithium battery life and the total charge capacity of the battery, and charging times. Deep feed deep and shallow charge for the influence of the li-ion battery life. Then, some MP3 manufacturers, said the propaganda "so-and-so type MP3 use strong lithium batteries, rechargeable more than 1500 times." This is purely ignorance deceives consumers.

Shallow put lightly, in fact, more beneficial for li-ion battery, only if the products do calibration for lithium electricity power supply module, it will have a deep filling necessary. So, the use of lithium electric power supply of the products don't have to be constrained in the process, all for first and charge at any time, don't have to worry about life.
