On the cell phone lithium battery of knowledge

This part is the focus of this article, we talk about three points.

1, how to charge the battery for a new

The use of lithium batteries should be noted that a period of time after the battery is placed into hibernation,Hp laptop battery
lower than normal capacity at this time, use of time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycles the battery can be activated to restore to normal capacity. As the lithium battery's own characteristics, its decision is almost no memory effect. Mobile phones so users of the new lithium battery in the activation process does not require special methods and equipment. Not only the theory that, from my own practice point of view, from the outset on the use of standard method of charging that "activation" approach is the best.

For the lithium battery "activate" problem, many say is: recharge time must be more than 12 hours, HP DP390A Battery, HP PP2100 Battery, HP Presario R3000 Battery(compaq r3000 battery),repeated three times to do in order to activate the battery. This "The first three charging more than 12 hours to charge" was obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that a beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics are very big difference, but also very clear to tell you that I have gone through all the serious official stressed that technical information and charge-off will discharge lithium batteries, especially lithium liquid ion battery causing great harm. Accordance with the standard charge and therefore the best time and the standard method of charging, in particular, not to carry out more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.

In addition, lithium batteries cell phone or the charger will automatically stop after the battery is full charge, there is no electricity nickel charger for 10 hours of the so-called "trickle" charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change and the quality of fail-safe, so your battery will be a long-term at the brink of danger. This is also another charge against the chief reason.

In addition, in some mobile phones, charging more than a certain time, if they do not remove the charger, this time not only to stop charging system will start to discharge - charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that 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 at night, but to our power grid situation, at night in many places higher than the voltage, but also volatile. As already said, HP DP390A Battery, the lithium batteries is very precious, and it more than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.

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

2, normal use should be when to start charging

In our forums, often see this argument, because the number of charging and discharging is limited, so phone the battery should be used up as much as possible recharge. But I found one on the lithium-ion battery charge and discharge cycle test table,HP DP390A Battery, HP PP2100 Battery, HP Presario R3000 Battery(compaq r3000 battery), on the cycle life data is as follows:

Cycle life (10% DOD):> 1000 times

Cycle life (100% DOD):> 200 times

DOD is the depth of discharge in which the English abbreviation. Can be seen from the table may be the depth of charge and discharge times, 10% DOD cycle life than when the 100% DOD for much longer. Of course, if the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter a full charge and discharge, or better than some, but in front of friends do say that some of the amendments: Under normal case, you should have a reserve battery power is left in accordance with the principle of charging run out of charge again, but if your battery in your first two days can not be expected to persist throughout the day, when they should start on time charge, of course, if you are willing to back the charger to the office again a different matter.

And you need to recharge in order to cope with the anticipated upcoming busy communications will lead to an important event, even though there are a lot of battery power over time, then you just charge ahead, because you are not really lost, "a" sub-charge cycle life , that is, "0.x" times only, HP PP2100 Battery, and often this x will be very small.

Run out of battery power and then filling the remainder of the principle is not want you to go to the extreme. And long, like charging a widespread view that "as far as possible the cell phone battery power runs out, it is best to use automatic shutdown." This is really just practice on nickel batteries, The purpose is to avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, still do not charge to continue to use the example has been used in automatic shutdown. The results in this case, cell phone charging and starting later in the no response, had to give customer service overhaul. In fact, this is because of the battery caused by excessive electrical discharges in low voltage, so that does not have the normal charge and the boot and conditions.

3, for lithium batteries cell phones right way

To sum up, I lithium batteries used in mobile phone charging and discharging, the most important tips are:

1, in accordance with standards and procedures, charging time, even the first three have to do so;

2, When the phone prompts when electricity is too low, we should try to begin charging a timely manner;

3, lithium batteries do not need to activate the special method,HP DP390A Battery, HP PP2100 Battery, HP Presario R3000 Battery(compaq r3000 battery), in a normal cell phone use lithium batteries will naturally activated. If you insist on spreading the use of "the three previous 12-hour long activation charge" approach, in fact there will be no effect.

Therefore, all the pursuit of super-long 12-hour rechargeable lithium battery cell phone use and the integration of the practice of automatic shutdown, are wrong. If you have previously done in accordance with the wrong argument, please correct in time, perhaps not too late.

Of course, cell phones and chargers to protect themselves and control circuit good quality cases, HP Presario R3000 Battery the protection of lithium batteries is still quite guaranteed. Therefore, the charge is the focus of understanding of the rules, and in some cases also may make some concessions. For example you find in your cell phone the night before bed charge, you can also start charging before going to bed. Crux of the problem, you should know what the right thing, and do not deliberately wrong to do so in accordance with.

Would like to younet with friends on the concerted efforts to grasp the knowledge about lithium batteries lithium batteries and learn the proper use of the scientific method, early in the lithium battery cell phone has long been an error with the spread and practice of saying good-bye.
