first time to charger battery
The use of lithium dell laptop battery should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, use of time has also come to shorten. But the very capacity of lithium batteries
Easy to activate, 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 laptop 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 to adopt
With the 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, repeated three times to do in order to activate the battery. This "The first three charge should be sufficient
More than 12 hours "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
The charge-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 overcharge and over-discharge lithium would
Pool, in particular liquid lithium-ion battery causing great dell Inspiron 4100 battery 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. That
, 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 safety,
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. Maybe
This approach has the vendor 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,
The situation with China's power grid in many places at night have higher voltage, but also volatile. As already said, the lithium dell Inspiron 2500 battery is very precious, and it more than nickel in the electric charge and discharge aspects of resistance to
Fluctuations in the capacity of 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. However, I find
To the one on lithium-ion dell Latitude CPX battery charge and discharge cycle test table, 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. Sure
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 that claim to be
To do some amendments: Under normal circumstances, you should have reserve dell Latitude C600 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
During the day time, you should start on time charge, of course, if you are willing to carrying a 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, 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 used up,
Best to use automatic shutdown. "This is really just practice on nickel dell Latitude C610 battery, The purpose is to avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. Once
Were 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
There was 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 dell Latitude C640 battery do not need to activate the special method, 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"
Method, in fact there will be no effect.
Therefore, all the pursuit of super-long 12-hour rechargeable lithium dell 1691P 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 and timely, and perhaps not too late.
Of course, cell phones and chargers to protect themselves and control circuit of good quality cases, 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.
In other words, a new generation of cells have not so much stress, and more convenient, casually when I wanted to charge to charge dell 75UYF battery, as long as no charge blasting machine like!

the decision lithium battery
First, the nominal voltage of power adapter normally dell laptop battery refers to the open circuit output voltage, that is, do not take any load, there is no current output voltage value. Therefore, that this is the power supply output voltage limit. For the internal use of the initiative power supply unit or voltage regulator components of the benchmark, in general the use of high resistance DC voltmeter can be directly measured nominal voltage (electromotive force should be a more accurate method of bridge belongs to the University of General Physics course experiment, not repeat them here), even if the mains voltage fluctuations in a certain place, is laptop battery secure in its output a constant value; but for a small market, low-cost transformers, such as the Walkman and the like to the type used is basically the traditional magnetic core transformer with four rectifier diode bridge rectifier coupled with a large filter capacitor on the bin, and so if you use common dc voltage meter measured value will be greater than the nominal voltage, because the output of bridge rectifier pulsating DC, simply said to be a sinusoidal voltage signal is a half weeks of time connected chain, after going through the filter capacitor will become flat after some, but the ripple coefficient remains high (ripple coefficient is the same magnitude of voltage signal fluctuation the average voltage ratio, the smaller the closer description voltage direct current), the so-called nominal voltage refers to the time integral of this voltage divided by the integration time, simple to understand is the dell D5318 battery right time, on average, if an ordinary DC Voltage Meter , measured value is very close to the maximum value of the voltage signal, so uncertainty. At the same time, if the electricity fluctuate, the output of such power will change as well.
In general, the real average no-load voltage of the power adapter is not necessarily exactly the same nominal voltage, because the characteristics of electronic components can not be exactly the same, so it allowed a certain margin of error, civil cases according to the need to control the use of 0.1% to about 5%. The smaller errors, the consistency of demand for electronic components, the higher the cost of industrial production, the higher the price of course, the more expensive.
Secondly, the power supply nominal current value. Regardless of any power supply has a certain amount of resistance, so when the power supply output current when the voltage drop in the internally generated, is equal to the output current multiplied by the power supply resistance. Led to two things, one is to produce heat, is equal to the square of the output current multiplied by resistance, so the power will be hot, the other is the nominal dell G5260 battery voltage minus the output voltage becomes the internal voltage drop, resulting in lower output voltage. The design is usually completed in considering the heat issues, the general restrictions on a current value, when the output current to achieve this is worth the time, the output voltage is reduced to 95% of nominal voltage, or other ratio, the manufacturers of products according to the different needs of the load can be set up be higher or lower proportion of the current value is the nominal current. Such as 72W power adapter for ibm16V nominal current is 4.5A (16 * 4.5 = 72, nonsense). If the load resistance is too low, resulting in the output current exceeds the nominal current, generally two things will happen, one more than the individual components due to heat capacity resulted in the burning dell G5266 battery heat damage caused by power supply, and the other is the thermal design margin left, only reflected in to further reduce the output voltage, if the decline too much may cause the load not work correctly.
To understand these concepts, we can determine the second question of this article. The same nominal power supply voltage, output current is different, the same can be used in the books. The underlying principle is the nominal current of large power can be replaced by a small nominal current of the power. Some of our friends there was any misunderstanding, I feel great nominal current of the power will burn books, because the current big Well. How much current is actually the same situation in the voltage depends on the load, that is, the work of books, when the books when the high load operation, the current was much bigger when the books go into dell Latitude CPi battery standby, the current on the smaller, short current equal to added to the books the voltage divided by the books on the equivalent resistance. Large nominal current power supply has sufficient current margin and will not replace the current power after a small nominal output voltage is too low or overheating situation. On the contrary, with a small current is replaced by high-current power supply on the existence of such a risk. But some friends instead of 72w with a 56w power supply is also no problem with them, because the power adapter is usually designed to leave a margin, load power must be less than the power supply power, so this place is in general use feasible, but the margin on the remaining Power are few, and the books once you pick a lot of peripherals, such as the two usb hard dell Inspiron 8200 battery drive, and then cpu running at full speed, and then there is a base with a drive at full speed to read the disk, and then with the same time charging the battery, estimated to be dangerous, it is necessary to keep your hands touch the power supply is not already a boiled egg. 72w more than the 16w adapter, 56w is the deal with this situation. So it is best not to use the small high-current power instead of high-current power supply. If you really do, conditional friends can try to Cece largest consumer of your books, when the actual needs of current measurement method is simple, a socket, a plug, an ammeter, Jigen wire, a soldering iron can be. If you have the power within the nominal dell Inspiron 8000 battery current, of course, is safe.
Answered the second question, the third question is very simple. Let us not doubt the power of your problem, first look at your books are doing, is not like the above said two usb hard drives, cpu running at full speed, hard disk read and write crazy, drive at full speed to read the disk, while charging the battery, loud the music, the screen brightness of the largest wireless network card has been detected signal, etc., make good use of power management, according to mandate a reasonable adjustment of the working state of books is very important. Many people do not like to use power management, I can even see a lot of friends after the installation of the power management software does not want any kind of management mode is enabled, then he should still be doing? Will not be just to see if the battery is left by How many, right?
As to the fourth question, the question of who is likely to electronic circuit is an outsider. Power to the books to the books and battery power supply is different, first of all that battery-powered, the battery's output is pure DC, very clean, direct access to DC transformer modules can be, the battery voltage is neither possible nor need to design very high, microelectronic circuits analog signals and digital signals to 5V voltage demand is now largely bounded by the dell Inspiron 8100 battery efficiency and remove the transformer module's pressure demand, 10.8V sufficient, but the decision lithium battery chemistry EMF the core of a power-saving 3.6V output voltage can only be around, so a lot of batteries are based on three series of the way, 10.8V have become a very popular battery voltage. Some of the battery 3.6V nominal value of an integer multiple of slightly larger than some, such as 3.7V or 11.2V, and so, in fact, in order to protect the battery (a very small number of manufacturers would discharge the battery termination voltage is set at 3.7V), or in the calculation of the battery When the design capacity of the manipulation. If you use the power supply, the situation is more complex, first of all need to join the voltage regulator further filtered to ensure that the power performance is not a good situation stable jobs, the voltage regulator after the two-pronged, all the way to the books Working power supply, another way to charge the battery, power supply to the books of that part of the experience when the same with the battery-powered, and give that part of the battery through the battery charge control circuit can be added to the batteries, the control the circuit can be very complex, it simply should include the primary regulator, precision tunable voltage regulator, SCR conditioning pulse output, regulated output, current feedback, the process of recording and computing chip, charge, charge self-feedback regulation process parameters, etc., so supply voltage must be greater than batteries have sufficient differential voltage is supplied to the charge control circuit margin of each unit. Really added to the final voltage on the batteries is by no dell Inspiron 4000 battery means 16V, please rest assured that is worried about a friend.
