1, how to charge the battery for the new

The use of lithium batteries should be noted that after some time the battery is placed into hibernation, lower than normal capacity at this time, the use of time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal battery charge and discharge cycle can be activated to restore normal capacity. As the battery lithium own characteristics, its decision is almost no memory effect. Therefore, the new lithium Apple battery cell phone users in the activation process does not require special methods and equipment. Not only in theory that, from the practice of my own, from the outset the standard method of charging that “activation” approach is the best.

For lithium batteries, “activate” issue, many said is: charging time must be more than 12 hours, repeated three times to activate the battery. This “three times before charging to charge more than 12 hours” the statement obviously is from the nickel battery (such as nickel cadmium and nickel hydride) inherited view. Therefore, this argument can be said to misrepresent the start. Lithium and nickel battery charge and discharge characteristics are very different, and can very clearly tell you that I have had access to technical information for all the serious official stressed the overcharge and over discharge will have lithium batteries, especially lithium liquid Ion battery causing great harm. Therefore the best charging method in accordance with standard time and standard charge, especially not for more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for charging the mobile phone standard method.

In addition, lithium batteries cell phone or battery charger will automatically stop after full charge, there is no nickel-power charger for 10 hours the so-called the “trickle” charge. That is, if your lithium batteries in full, on the white charger is also sufficient. We can not guarantee anyone the battery charge and discharge protection circuit features and never change the quality of safety, so long your battery will be hovering at the edge of danger. This is also another charge against the chief reason.

In addition, in some mobile phones, charging over a certain time, if not remove the charger, this time not only to stop charging system, will begin discharge – charge cycle. Perhaps the makers of this approach has its own purpose, but apparently the battery and cell phone / charger is detrimental in terms of life expectancy. At the same time, long charging would take a long time, often require night, but to our power grid situation, at night in many parts of the voltage are high, and volatile. As already said, the lithium battery is very delicate, and its power than the nickel-resistance in the charge and discharge aspects of fluctuations in the capacity of much less, so this brings additional risk.

In addition, another aspect can not be ignored is also not suitable for Li-ion battery over discharge, over-discharge of the lithium batteries also very unfavorable. This leads to the following questions.

2, normal use should be when to start charging

Often see this argument, because the frequency of charging and discharging is limited, so it should be possible to run out of phone battery power recharging. But I find a lithium-ion batteries on charge and discharge cycle test table, on the life cycle of data is as follows:

Cycle life (10% DOD):> 1000 times

Cycle life (100% DOD):> 200 times

Which is the depth of discharge DOD abbreviation. Can be seen from the table, number of charge cycles and the depth of discharge, 10% DOD cycle life than when the 100% DOD for much longer. Of course, if the relative charge equivalent to the actual total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter fully charge and discharge, Fujifilm battery or better than some, but the previous users of that claim to do some amendments: Under normal case, you should have reservation in accordance with the remaining battery power runs out and the principle of full charge, but if your battery is expected in the first two days you can not adhere to time throughout the day, you should start charging time of course, if you are willing to back the charger to the office has a different matter.

And you need to charge in order to meet the anticipated upcoming busy communications will lead to an important event, even though there are a lot of battery power over time, then you simply charge ahead of time because you do not really lost, “1″ charge and cycle life , that is, “0.x” plays it, and often this x will be very small.

Run out of battery power and then filling the remaining principle is not to your extreme. And long, like charging a very popular saying that “as the phone battery run out, the best use automatic Shutdown.” Actually, this is just practice on nickel batteries, seeks to prevent occurrence of memory effect, unfortunately, it is also circulating on the current lithium. It has been because the cell phone battery low warning appears, is still not charging to use the example has been used in automatic shutdown. The results of this case in the later charge the phone and boot in no response, had to give customer service overhaul. In fact, this is the result of excessive discharge as a result of the battery voltage is too low, so do not have a normal result of the charge and start conditions.
