Notebooks use lithium batteries
Now use the notebook more and more people, as the notebook one of the main components of lithium battery problems have also increased. So how should make good use of the laptop's lithium batteries do? Is to grasp two points:
1. Due to current red discharge.
2. To minimize the discharge less than the over-charge or discharge.
While the battery is a consumable, lithium-ion battery is no exception. However, no one wants to use the battery up the fine spirit of God, not the age that you snap on the end, no one wants to own the very beginning, half dead battery does not pull a living, this has been the rub in 2023, making good You realize how little value is the case, you do not say that?
Well, get down to business, following the battery began to speak. To explain, is limited to lithium-ion battery.
Appropriate to charge and discharge current
Literature in general and the state on the standard lithium-ion battery that the lithium-ion battery charge current should be between 0.2C to 1C. It is said that the capacity of the battery charge current, such as your battery is 4AH, then the 0.2C charge current is 0.2X4 = 0.8A, in other words, the charge current should be between 0.8 to 4A. In general, in charge current to the extent permitted by the smaller the better, rechargeable lithium-ion battery to start charging current stage should be, in my IBM R31, this current is 2.8A or so, which is equivalent to 0.7C, is charging its own circuit Control, can not be set. This indicator does not charge more than the standard, but do more, especially when using the battery capacity decline for some time after the charge current may be more than 1C. Now the length of time charge notebook users have also become targets regardless of the manufacturers were forced to charge current set so high.
So the first step is to reduce the charge current. I have friends working in the laboratory, a variety of readily available equipment, where he is on trial for a moment. Power output in the first string on a try resistance, the outcome of the current is reduced, but became intermittent charge, which is not a good thing. Through trial and error, 4 Ohm is a more ideal value, this time around 0.8A charge current is, very stable. This is only run through the machine's current power supply interface, the battery charge current estimated number of large, it should be slightly larger than 0.2C. Specific to a different machine, this value may be different. With the addition of the increase in battery voltage, charge current will be reduced, but decreased only slightly less than 0.05A. In such a state of charge, charging circuit seems to be not working, the battery indicator light is not bright. Such as the battery voltage up to 12.6V, charging circuits came into play into the battery trickle charge, at this time whether the series has resistance does not matter, the charge current by the charge control circuit, the last full charge after the end of the circuit automatically charge. The entire charge time is about 5.5 hours, if not resistance, charging time is about 3.5 hours.
Lithium-ion batteries is very precious, good charge control circuit is necessary. This charging method can reduce the charge current, battery life, while at the same time the use of the books of the original charge of the charge control circuit, it is also relatively simple to achieve, just buy a plug (from the power supply into books The kind, it is best to buy two, referred to the back of a method also used to good quality) and a can of resistance, resistance attention to the larger head, above, after all, there are about 2W of power Otherwise, it would be more heat resistance, the best use of their constant resistance to be a wire, the wire resistance of the resistance and temperature has nothing to do basic. But the shortcomings of this approach is obvious, that is not in charge of the work at the same time with books. Another charge when there will be a strange phenomenon, I do not write omitted here, you try to know, the good news is this phenomenon into the trickle charge after the state disappeared. Charging time is not a big deal, anyway, before the charge to sleep at night, wake up the next day on the charge Well, of course, if you are a person who goes to bed to bed or short-time special, it is a different matter. f4098a, f4809a, f4812a, 319411-001, presario 2100, presario 2500 Small charge current issue is resolved, the issue is now the turn of the discharge. In fact, this is difficult, after all, the book is designed to work, the discharge current will work with the state vary, here referred to the method used to be limited to special battery capacity to resume operation.
Start machines, power management settings do not always sleep (standby) and hibernation (hibernate), as are most other power-saving mode, including the CPU speed, hard drive shut down, turn off the display, and so on, and TP in the management process Do not have to shut down some of the hardware, such as sound cards and so on, and then open the battery status display window, to run in front! ! ! The closure of other programs, in particular, screen saver and the other from time to time to run the program! ! Do not use the machine, do not close the lid and let the battery discharge end (not to discharge the minimum value set to 0, I set up 3%). Display and hard drive shut down after the discharge current is about 0.5A, this is my IBM R31 can be achieved at the minimum discharge current, battery discharge to the minimum value after the machine will automatically shut down. Continue to discharge the entire time about more than 4 hours, according to your battery capacity may be different, this time to sleep is also a way to use the pass.
Well, the last to stress that the above-mentioned method is not dead, especially the discharge, there are ten time will be able to do so, otherwise the battery still doing? Charging the best use of small current charge, of course, if the battery urgent need for a direct power supply to plug inserted in the book on it.
I used this method of battery, put a charge 14 times the capacity has been maintained at over 45, and the design of the battery capacity is 43.2, which is also declining, but this release Filling time after the restoration of.
Speaking at the beginning of the two points, one appropriate charge and discharge, and the other is not to discharge less than the charge, discharge following a look at how to solve the problem of lack of charge on it:
To minimize the discharge less than the over-charge or discharge
In fact, a very good solution to the excessive discharge, not to terminate the limits of the discharge can be so low, I have been using 3%. f2299a, f3172a, pavilion zt1000 Often do not use batteries may be a long time, such as the battery remaining 70%, if the power switch, then the battery is automatically recharged, there will be no such a cycle, although battery life is not a cycle in order to set the absolute number of dead, But always it will reduce the capacity of the battery, lithium-ion battery was no memory effect, but it is just a memory effect it is relatively low. Unfortunately, IBM did not provide the solution to the shortage of charge-discharge method, but provides a solution to this problem. And that is what I found on the R31 may not necessarily suitable for other machines, but the method should also be more or less the same, you try not to forget after it posted for all to share.
R31 charging circuit based on the situation of the power to decide whether to charge the battery. Power output voltage is 16V, the error of plus or minus 0.2V, if the voltage lower than 15.5V, so not to charge the battery charging circuit, and the book can work, which is provided by IBM to solve the problem. But this is the basis of vulnerability, as if the lower voltage 15.2V, books will be converted to use battery-powered, plug in the power supply even if the books will be of no avail. In other words, we can toss the space is 0.3V.
If you can find a 15.5V, over the current 3A switching power supply, then the problem is solved, otherwise please continue to look down.
The power to reduce the output voltage 0.5V is not an easy thing, the series resistance is not ideal because of the resistance as the current size of the voltage changes. I use the diode rectifier to permit the adoption of the current 2A above, otherwise the heat pipe. Rectifier diode forward voltage drop in the 0.7 to 0.5V, just to meet the requirements. Now this type of electronic tubes in the market are so high, the prices of less than 2 yuan. Specific to a different book may be different, it is best to install on-hand when there is a digital multimeter Test. Pipe is being in the series of power output, and then followed his own to buy a power plug inserted in the book. Then the anti-diode does not matter, be it the script does not work, and then in turn connected to it.
Like, power output voltage drop of 0.5V or so, if the drop too much, the book will switch to the battery, if the drop too low, the book will charge the battery, in particular how much you want to book their own tried to know.
Of course, if your battery has been full of this circuit there is no need, you can not have it, directly to the power output in the next book on it. f2019, f2019a, f2019b, omnibook 6000 Come to an end, the beginning of the two issues are resolved. Now you see the results of the test, it is estimated that in the book different results could be different, the best ones to take a circuit to try to avoid it took 10 innocent money 
Finally, I wish you good luck! You make good use of lithium batteries it!
To remind:
In the modified plug when the mistake is easy to engage in anti-polar (diodes engage in anti-polarity does not matter), so you must double-check by measuring multimeter and a different color of the wire connection is negative. I do not know engage in anti-polarity power supply will not burn the books, did not try!
With regard to the use of lithium-ion battery
1, for a new battery charge
In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the battery can be activated, the resumption of normal capacity. As the toshiba PA3384U-1BRS battery lithium own characteristics, its decision is almost no memory effect. Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the very beginning, the use of standard methods of charging that "activation" is the best way.
Lithium batteries for the "activation", a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. "The first three necessary and sufficient to charge more than 12 hours", it is obvious from the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not 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, the lithium battery in the phone or battery charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours 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 ibm ThinkPad T60 battery charge and discharge protection circuit features and never change the quality of safety, so your batteries will be in the long-term hovering on the brink of danger. This is also another charge against the chief reason.
In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge - charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that on the phone and battery / charger is the life span of a negative. At the same time, long charging would take a long time, often at night, and to our country's power grid situation, at night in many parts of the relatively high voltage, but also volatile. Said earlier, the lithium battery is very delicate 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, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.
2, in normal use when the charge should be
In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find on a lithium-ion ibm 40y6797 battery charge and discharge cycle test table, on the life cycle of figures is as follows:
Life cycle:> 1000 cycle life:> 200
DOD is the depth of the discharge of which the initials. Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD's a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative: 10% * 1000% * 100,100 = 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: normal Under the circumstances, you should have a reservation in accordance with the remaining battery power and then run out of filling the principle of charging, but if your battery is expected in the first 2 days you can not adhere to the whole day, should start on time charge, of course, if you are willing to back A charger to the office and when Bielun.
And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if there are a lot of battery power over time, then you just charge ahead of time because you do not have a real loss "1" sub-charge cycle life , That is, "0.x" times, but often this will be a very small x.
The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread view that "as far as possible the cell phone batteries run out of power, it is best to use automatic shutdown." This is only a matter of fact on nickel batteries, to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone was in charge of the boot in and there was no response, had to give customer service overhaul. In fact, this is due to the ibm 40Y6799 battery as a result of excessive discharge and led to the low voltage that does not have the normal charge of the boot and conditions.
Lithium batteries for mobile phones boils down to the correct approach, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with the standards and procedures, charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;
3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of "three times before the 12-hour long activation charge" approach, in fact there will not be the effect.
As a result, all 12 hours long pursuit of the lithium batteries and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.
Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium batteries or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.
8 Apple iPhone mobile phone ibm thinkpad r60 battery life 675 days Thu, 26 Jul 2007 00:40:45 +0800 Apple iPhone mobile phone is really a lot of press recently, PC MAG and even an in-depth study about the Apple iPhone's battery life. They believe in the best case, iPhone's battery can only be 675 days.
The data was something like this. According to official documents show that Apple, iPhone mobile phone battery charge and discharge in full after the 400 could reach 80% of the total electricity consumption. After user feedback, iPhone an average of 30 hours a need to recharge, PC Mag is the result of precise measurement 34 hours (which is estimated for charging an average of 1.5 days). The Apple iPhone is fully charged, the time is 4 hours. In accordance with the best of the situation and at the same time to each battery charge after the loss of electricity is included in the calculation, the battery life is 675 days.
Even in the off-line program, enter their mobile phone to buy Apple's iPhone will be able to arrive at the date of the date of the batteries need to be replaced
Some users have already released the iPhone to extend mobile phone battery life.
Upgrade to the latest software upgrade to the latest iPhone will allow more power.
3. At least once a month full charge and discharge your mobile phone iPhone, so the ibm FRU 92P1139 battery can be maintained at its best.
When you use the iPhone do not remember a time when mobile phone screen lock.
4.'s Not the best time to turn off wireless and Bluetooth.
Open the automatic brightness adjustment, this feature can help save power.
Turn off the music player's equalizer settings. Can contribute to saving energy.
