When should the lithium battery be charged in normal use

　　In our forum, we can often see this statement. Because the number of charges is limited, the electricity of the mobile phone battery should be charged as much as possible with light. But I found an experimental table of the lithium ion battery charging and discharge cycle.

　　Cycle life (10%dod):> 1000 times

　　Cycle life (100%dod):> 200 times

　　Among them, DOD is an English abbreviation with depth of discharge. It can be seen from the table that the number of charging times is related to the depth of discharge. The cycle life at 10%DOD is much longer than 100%DOD. Of course, if the relative total capacity of the actual charging is discounted: 10%*1000 = 100, 100%*200 = 200, the latter's complete charging and discharge is still better, but the previous saying of the netizen should be made: in normal In the case, you should have a reserved place to charge the principle of using the battery's remaining power, but if your battery cannot insist on the whole day of the day, you should start charging in time. Of course, if you are willing to carry back The charger went to the office to be another matter.

　　And when you need to charge to cope with important events that are expected to lead to a busy communication, even when there are still many electricity in the battery, you can only charge it in advance, because you do not really lose the life of the "1" charging cycle life. That is, "0.x", and often this X will be small. The principle of battery remaining power is used up and re -charging is not to go to extremes.

　　One of the extensive explanations like the long charging is "try to use the power of the mobile phone battery as much as possible, it is best to use it automatically." This approach is actually just a nickel battery. The purpose is to avoid the memory effect. Unfortunately, it is also circulating on the lithium battery. Someone once did not charging after the warning of the mobile phone battery power was too low, and continued to use it until automatic shutdown.
