A. It was sold in the batteries for notebooks after more than three times the continuous 12-hour rechargeable battery, to prevent “memory effect”

First ask a very idiotic problem: my friends have mobile phones it » Many of my friends in the use of mobile phones will consciously or unconsciously in accordance with the businessmen or others advise to do one thing, is to buy back the phone after the first three batteries are necessary and sufficient to 12 hours of electricity, and then, exhausted, and so only after further Filling. Reason to worry about their friends because the cell phone battery “memory effect,” memory effect is long battery cycle through specific work, automatically maintain this particular trend. So every time someone said that if only 50 to charge the battery % Of the time to get started, then the memory effect after the battery will charge the next time is sufficient to only 50 percent of the time on the “do not get the filling.” In fact, this “memory effect” that is the nickel-cadmium and nickel-metal hydride batteries, lithium-ion laptop batteries, the memory effect is almost negligible.

With the gradual improvement of the manufacturing process, lithium-ion rechargeable battery, such as the constant current of its deep-charging time control in four hours, there is no need to recharge the batteries of mobile phones get laptop batteries Of notebook battery, a charge on every dormant for two weeks or a month’s time, the laptop battery will conduct a depth of discharge, the term sounds a bit scary, in fact, is to use battery-powered, and then did not directly use the computer, automatically Off it. However, the number of deep discharge should not be too frequent.

B, using the AC adapter when the battery should be unloaded first, to avoid the batteries “explosive charge”

Currently used in notebook market lithium-ion batteries can be completed 300-600 (some data that can be more) of the charge and discharge process, we can calculate the, now on the market for sale Centrino models of battery life for the general official data for more than 5-6 hours, the Pentium 4 models battery life time for three hours, then to lithium-ion rechargeable battery discharge 600 as the standard, its notebook batteries can use long Time can be calculated by. Some friends in the use of the AC adapter when the battery down from his concern that if the battery inside left more power, the AC adapter plug on the results start charging, the battery of his wasted a so-called ” Number of charge cycles. ” In fact, this worry is unnecessary, because the laptop battery power can not be 100 percent sure of the state, using an AC adapter is certainly the time to complete the charging. But now many manufacturers of notebook computers are designed a battery protection measures, such as IBM’s notebook in power only less than 95 percent of the time before a charge, but not absolute, some did not rely entirely on the design capacity of the notebook OEM manufacturers In this regard may also some weaknesses. If you really pained own battery, it may wish to remove come!

Battery explosion of the risk of small things. But not absolute no, lithium-ion battery inside of lithium batteries, and they have a control board and management to complete the charge and discharge, if this control circuit some of the features of the original loss of the sensitivity of direct or failure will not be effective Current control, internal batteries temperature increases lead to the explosion. The internal battery or batteries will be a short-circuit in the explosion. But now the market is good that the notebooks are based on foreign high-quality batteries or directly buying other people’s batteries, a relatively better quality. The domestic part of the lithium-ion battery manufacturers are also more foreign imports and the batteries manufactured. So is an old saying that sentence, in the selection of notebooks, as many as possible ready to consider some budget products maker, correct.

C, battery life time did not meet official standards, certainly battery problems

Buy notebook all the friends will worry about this problem. Indeed, with Centrino notebook technology makes the birth of access to longer battery standby time possible. There are even manufacturers of notebook computers even more marked on a 10 hour “battery life standard.” In fact, this is just a grab the attention of consumers advertising only. Most laptop batteries are not achieve the so-called “official standards”, maybe my friends will recall that Asustek’s energy-saving technology patents Power 4 Gear technology (also upgraded version of Power 4 Gear +), known as M6 series of books will be battery life Extended to 5.5 hours, but Asustek’s sales staff told the author of the books of the time battery life for three hours about it. Of course the other hand, battery life for the manufacturing process is not our consumers can solve. So when the time did not have battery life, “the official battery life standards” when friends not surprised, not so long because of the use of time is a normal (if your notebook battery life time to reach the official standard, then please do not Paizhuan, I said that the majority of books).

Friends if the battery standby time has reached less than “the official standard battery life,” then we can through a number of ways to extend the:

1, 25 ℃ ~ 40 ℃ the use of standard external environment, the use of lithium-ion batteries can be best achieved if the temperature is too high, Not only their own laptop computers or even slow down the speed crashes, and the battery in this environment will also affect the efficiency of its use. So as far as possible in the indoor environment using a laptop.

2, not commonly used to disable the equipment. Peacetime use of battery power when the best do not need to temporarily disable the interface are out, such as wireless card, printer port, infrared interface, 1394 FireWire interface, and so on, will not waste a lot of battery power, the specific method is ” Control Panel “-” system “- the” hardware “-” Device Manager “of the disabled to find their own equipment, then click on” inactive “on the need to use the time to” enable equipment “, is very simple. After the use of banned performance quite obviously, can save a lot of electricity.

3, reduce internal power consumption. Increasing the CPU speed, high-speed drives will bring a lot of energy consumption and increase the heat. Therefore, no special requirements, or the best use of the system or third-party software to control the speed drive, do not open too many windows and procedures in order to avoid CPU overload of work, so not only can reduce the battery power consumption, and can also reduce powder Hot, “Qiu Laohu” there is a season, it still has some advantages.

D, start-up rechargeable batteries for notebook very harmful

Boot charging in the end there are no victims » I once saw a Gemen boot my phone is charging, and then from that one: wow! You even dare to start-up charge, you are not afraid of battery explosion! » Although a joke, it reflects the many friends of the use of errors. In a notebook, before the design is, if some models now use battery-powered, then even if the AC adapter plug, books or the use of battery-powered, which is “sufficient and do not get” the phenomenon of today’s notebook computers are not so In the design of the danger, when the plug in the AC adapter, external power supply immediately and to begin to charge the battery. So now there is no need to recharge the shutdown.

E, long battery not casually placed on the side

This problem users are often overlooked. But this issue from time to small, and I talk to the engineers told reporters notebook, many notebook manufacturers on the proposed user in control of the battery power more than five percent of this approach is to remove the electrode passivation, because laptop battery factory in The time has already begun the slow self-discharge (activate the battery in the workshop on the matter has been completed, we do not need to worry about), a notebook may be in default six months after the purchase of consumers, and the battery has a six-month discharge The. I suggested to my friends here is the long-term if not used battery-powered AC adapter, the best laptop batteries to stay on 40 percent - 50 percent of them - more than self-discharge, if there is no electricity, then let the battery - , It is easy to problems or even scrapped. You want to, ah, self-discharge is certainly to take, but not inside it - you put what, ah, no problem Caiguai!

There is a need to pay attention to the question: if no long-term battery-powered and powered by an AC adapter (for example students), put the battery in a cool dry place such as cabinets. This approach was to avoid the humid environment, and if not, the best books of the battery and placed separately, do not believe we bought the phone and look at the books of attention, businesses are not separated from the cells and placed the

F, the Dead but there is no way to pull the battery

I have seen some friends before machines can not be normal shutdown of the phenomenon, or even shut down illegal not feasible to Guai Jiuguai the great “fainted dead” system! Finally on the big brother who directly to a two Duojiao eyes closed a three to pull the battery, only heard on the books Yishengcanjiao closed. In fact, this approach is very harmful, because they stand in the state, and the memory is the power, if hasty directly from the battery down, loss of data is inevitable, not in the AC adapter into the time for battery This can only harm is no benefit

1. To the appropriate current-discharge.

2. Minimize the discharge less than the over-charging or discharge.

Although the battery is a consumable, lithium-ion battery is no exception. But no one wants the battery to the fine spirit of God, to the age should not clicks on the finished, no one wants to own a battery start Bansi not pull the living, has been on 23 such Ceng, good people Experience is the chicken ribs matter how you say it is »

Well, Yanguizhengzhuan, below the battery began to speak. The first note, only lithium-ion battery. Current appropriate to charge and discharge

General literature and the state on lithium-ion batteries on the standards that the lithium-ion battery should be in charge current 0.2 C to 1 C between. This is the battery capacity that the charge current, such as your battery is 4 AH, then the charge current 0.2 C is 0.2 X4 = 0.8A, that is the charge current 0.8 should be between 4 A. In general, in charge current extent permitted by the smaller the better, lithium-ion batteries for the initial stage should be constant current charging, in my IBMR31, this current is about 2.8 A, equivalent to 0.7 C, is charging its control circuit And can not be your own. Although such a charge has not exceeded the standard indicators, but they do more, especially when the use of battery capacity decline after a period of time, the charge current may exceed 1 C. Charging time now notebook users regardless of the length has become the target of the forced manufacturers to charge current set so high.

So the first step is to reduce the charge current. I have friends in the laboratory work, all furnished, in a trial to him. Power output in the first on a string try resistance, the current is reduced, but became intermittent charging, this is not a good thing. After repeated tests, 4 Ohm is a more ideal value, this time the charge current is about 0.8 A, very stable. This is only the power flows through the interface of the current machines, battery on the charge current estimated to be larger, it should be slightly larger than the 0.2 C. Specific to a different machine, this value may be different. With the addition of the battery voltage increase, the charge current will be reduced, but the decrease rate is very small, less than 0.05 A. In such a charged state, charging circuit seems to be non-functional, battery indicator light is not bright. Such as the battery voltage up to 12.6 V, charging circuit came into play, the battery into the trickle charge, and this time whether the series resistance has been insignificant, the charge current is controlled by the charging circuit, the last full automatic charging circuit after the end of charge. The charging time is about 5.5 hours, if not resistance, charging time is approximately 3.5 hours.

Lithium-ion batteries are Jiaogui, good charge control circuit is necessary. In this charging method, can reduce the charge current, extended battery life, while use of the books the original charge control circuit charge, and it is also relatively simple, just to buy a plug (that is from the power plug into the books The kind, the best buy two, the latter referred to in one way, to good quality) and a resistance can be, the attention of the resistance to the head, after all, are above about 2 W power consumption Otherwise, resistance would be more heat, the best use of their constant resistance to make a silk, silk such resistance and temperature for the resistance has nothing to do. But the shortcomings of this approach is also very clear, that is not in charge of working with books. In addition there will be time charge of a strange phenomenon, I omitted to write here, you try to know, Fortunately, this phenomenon into the trickle charge after the state lost. Charging time extension is not a big problem, since before the beginning of charge to sleep at night, woke up the next day on the charge of the good, of course, if you are sleeping Ye Maozai or special short time, different matter.

Small current charging issue is resolved, now turn to discharge a problem. In fact, it is very difficult, after all, the book is designed to work, work with the discharge current will differ by state, the method mentioned here only to be devoted to restoring the operation of the battery capacity.

Activated machines, power management settings in the state will never go to sleep (standby) and dormant (hibernate), are set to most other power-saving modes, including CPU speed, closing hard drive, display, and so close, and in the process of TP management Do not have to close some of the hardware, such as sound cards, etc., and open the battery status display window, so running in the future! ! ! Close other procedures, in particular a screen saver and other regular operating procedures! ! Do not use machines, do not close the lid, let the battery discharge end (not to discharge the minimum value set to 0, I set up the 3 per cent). Monitor and hard drive off after the discharge current is about 0.5 A, this is my IBMR31 to be able to achieve the minimum discharge current, battery discharge to set the minimum value after the machine will automatically shut down. The discharge time lasted about more than four hours, according to your different battery capacity may vary, the time is also sleeping with the means to kill.

Well, finally stressed that the above approach is not dead, especially the discharge, there are 10 times can do so once, or else to battery doing » Charging the best use the small current charge, of course, if the need batteries, plug directly into the book on it.

I used this method of battery, now put a charge of 14, capacity has remained at over 45, and battery design capacity is 43.2, which have decreased the time, but this charge after the all-time restored.

Beginning stresses two points, First, the appropriate charge and discharge, and second, not to discharge less than the charge, the following discharge look at how to solve the problem of insufficient charge on it: to minimize discharge less than the over-charging or discharge

In fact, the excessive discharge solved, not to terminate the discharge limits can be set at too low a level, I have been using three percent.

Very often just do not use batteries may be a long time, such as the battery remaining 70 percent, if the switch to power, then the battery is automatically charged, such a cycle would be no, although battery life is not absolutely determined to cycles of death, But always it will reduce battery capacity, lithium-ion battery said to no memory effect, but in fact only relatively low-only memory effect. Unfortunately, IBM did not provide solutions to discharge less than the charging method, but provided the basis to solve this problem. This is what I found on the R31, may not necessarily suited to other machines, but methods should also be close, do not forget after you tried to paste up the share.

R31 charging circuit in accordance with the power to decide whether or not the state of batteries. Power output voltage is 16 V, error of plus or minus 0.2 V, if the voltage is lower than 15.5 V, then charging circuit not to charge the battery, and books can work, which is IBM provided the basis to solve the problem. However, the foundation is weak, because if the voltage lower than the 15.2 V, books will be converted to use battery-powered, even if the power planted on the books is also useless. In other words, we can disruption of the space is 0.3 V.

If you can find a 15.5 V, over the current 3 A switching power supply, then the issue was resolved, otherwise continue to Read.

The power to reduce the 0.5 V output voltage is not an easy thing, the series resistance does not work, because of resistance on the voltage will change with the current size. I use the silicon rectifying diodes, through the current request to allow in more than 2 A, or tube is too hot. Silicon Rectifier diode forward voltage drop of 0.7到0.5 V, and just to meet the requirements. Now such tubes in the electronic market Duo Deshi, the price of less than two yuan. To a different book on the specific situation may be different, the best-on-hand for the installation of a digital multimeter Cece. The tubes are positive in the series connection of power output, and then followed by a buy their own power plugs inserted on the book. It does not matter to the anti-diode, the book does not work to critize, and then in turn connected to it.

In this way, the power output voltage drop of around 0.5 V, if the decline too much, the book will switch to battery life, if dropped too low, the book will charge the battery, the specific number to you in his book on the experience to know.

Of course, if your battery has been full of this circuit there is no need, you can use it, directly to the power output to the books on it.

Here, mentioned at the beginning of the two issues are resolved. Now you see the results of the test, it is estimated that in the book on the different results might be different, their best try to ride a circuit, so spent 10 wronged money

Finally I wish you good luck! You make good use of the lithium batteries! Reminded:

Plug in the modification of the most common mistake is easy to engage in anti-polarity (diodes engage in anti-polarity does not matter), so you must double-check with multimeter measurement, and use different colors of the wires are connected negative. I do not know engage in anti-polarity power will burn the books, not tried.

    In general, to buy a new laptop just follow the normal charge / discharge form can be activated

     Since 2007 the fourth quarter, Japan, South Korea core of the battery factory frequent accidents, NB-assembly plant and the brand is a headache, but also to the mainland of China given the opportunity to plant cell batteries, the battery company in the past, Sony had a large number of battery recycling NB , NB market has started to use substantially NB battery of Korea, now China battery factory Chen Shi-core rise, beginning attention.
  
     NB industry pointed out that Asustek EeePC part of the battery cell batteries from mainland China plant, Taiwan’s new battery factory in Cape mainland China also have to find the battery core factory and certified by HP, HP will be in a low-priced machine, used, but quality problems NB plant still dare not let this effect, only in very small portion of low-end consumer product line a try.

     At present, China’s main production to the mainland batteries in Shenzhen, including BAK International (ChinaBakBattery)’s wholly-owned subsidiary of Shenzhen BAK Battery (BAK), AmperexTechnologyLimited (ATL), and other battery-core plants, have made Asustek Computer, Hewlett-Packard certification, in 2008 the mainland of China Core battery factory Fushang table, the battery capacity is expected to make up for some of the gap.

     However, the mainland of China battery market is still questioned the quality of focus, NB battery life in recent years increasingly demanding, consider battery safety through the NB brand certification threshold, once the battery problems, so easily affected by the NB brand image. Recent channel market is the mainland of China reported two, three battery company has not been certified and authorized Asus, private sales and EeePC battery problems.

     Although NB plant to cope with the current growth in demand for NB and mainland China must import batteries, but the mainland of China battery market share of the total NB very low, if South Korea’s LG Chemical (LGChem) Availability still unable to catch up with the accelerated progress of the second half of 2008 NB season or market pressure may arise out of stock.

     Taiwan assembly capacity of the battery, the first quarter of the battery pack NB Although limited market effect of the low season, as well as lithium batteries hard-core issues of supply and demand, the overall output was still a slight increase over the same period in 2007, the first quarter of Taiwan’s energy output value amounted to NT components 16 billion yuan (about 4 billion yuan), an increase of 9 percent. In addition, the recent rumor that the intention to intercept and large battery market, solve NB Availability pressure, and a spokesman for YAO De-chee-seok, battery manufacturing certification threshold amount of investment are high, refuted rumored to be bought mainland China battery factory core rumours.

 Answer:Go to the power options and see if their is anything in their you can change mate .

 Answer:Below is a search result on ebay it is probably the cheapest you will find!

 http://www.new-laptop-battery.com/  or http://www.mainec.com/ 

 There have any you want type battery

  Have a good time .

  Answer:If you replaced the battery and it won’t charge it’s because your computer is drawing more current than is being supplied by the charger. It’s a simple In vs. Out situation. If the charger is supplying 100 milliamps of current but the computer is using more than that, the battery will not absorb a charge. You need a tech to monitor the current your computer consumes, and check the charger to see if it’s delivedring enough power.

  Answer:Maybe make sure that all of the wires are plugged in right. You could always take it to Office Max or somewhere else and ask them, but they may tip the scales so that you end up buying something from them.

  If it alway bad ,you will buy new battery .
