How you can pay for your battery, that the maximum life out of him
1) Always use your notebook on a hard surface. Laptops are portable and it’s just your laptop on the bed set and use it at your leisure. This is one of the advantages of a portable computer. Flexibility. But if you want your notebook battery life have to be careful with overheating to extend your notebook. Heat is a major obstacle for the life of the battery longevity. Your laptop computer fan can not circulate the air properly when you sit your laptop on soft surfaces. 2) Keep your battery installed, if your laptop use on AC for an extended period. While your notebook is undoubtedly an intelligent charger with a constant trickle charge over months, you can make your battery will be reduced. For best results, only charge your Dell XPS M1530 battery , if it need to charge, hold your laptop battery plugged in all the time. More importantly than the trickle charger influence is the “storage” of a Li-Ion battery at elevated temperatures. The ideal storage temperature for a Li-Ion battery is at 0 degrees. C. The optimum storage charge level is above 40%. Unfortunately, we tend to store fully charged and the temperatures found in a current notebook find a significant reduction in battery for your notebook performance after only 12-18 months to find. 3) Use a full charge cycle before recharging Li-Ion and NiMH battery (most notebook battery), have no memory, you could find Akkun-in NiCd. However, each chemical a limited number of charge cycles, so you use a full charge cycle before they are loaded again to maximize your Dell xps m1330 battery to use. Since this can be very difficult to manage, you need value for money to keep track of costs, how far the battery is discharged before charging to consider it again. 4) Be careful if you store your notebook, this goes back to the heat problem. Let your Dell Studio 1537 battery in the car, where it is very hot.Akkus hate the heat and the battery is permanently on strike, if you expose it, much heat can cause. Note that all notebooks are created equal no. You can get from your last laptop will have hours 4 while on laptop battery , but your new laptop could be more juice to that gaming processor, or the power hogging programs are now run quality pull walk. Read your manual to learn what you expect from your laptop battery and be sure to compare apples to apples when you buy a Dell Inspiron 6400 battery. Not all battery VGP-BPS8 specifications are the same make. We recommend buying a battery, at least as much capacity as the original battery (which is the mAh rating), and preferably has the same chemical as well.

Windows7 injury laptop battery,Microsoft is under investigation
In Microsoft TechNet BBS, an official users to post said, he put himself in 2007 buy an HP laptop from Windows Vista upgraded to the Windows 7, but battery 3000ibs but from two hours became just half an hour, Microsoft is repeatedly propaganda new system can greatly extend battery 3000ibs. Online BBS in other countries also have the similar questions.
It is reported, the root of the problem is that Windows 7 added a new Dell Inspiron 6400 battery measuring tools, can judge the battery needs replacing and notify users, but in some cases, though, the system will battery business-as-usual misjudgment, think battery has exhausted, and recommend that users replaced immediately, sometimes directly closed system. Customers have reluctantly reflect that he saw hints indeed re-edited with old battery, but new batteries are still continue to get the same warning.
Some say the problem in early July Beta testing phase Windows to exist, but also some say the official version of RTM just happen. A user to post said: "in installation RTM version 7 before my Dell xps m1330 battery Windows has been very normal, use time in my installed all Beta and RC edition can adhere to nearly three hours. Now, just about twenty minutes Windows 7 will bring my notebook to shut. The situation is in me from the RC steering RTM appeared. Needless to say, I like everyone very upset."
Microsoft said in a statement has been aware of the problem, and points out and Windows 7 read system firmware about the way, in many different types of manufacturer of notebook do exist. Microsoft said: "we are with hardware partners to survey the problem. Windows 7 to judge by the firmware information need to change the Dell Studio 1537 battery. But we are working with partners troubleshooting source, obtaining required information and guidance after will TechNet) in (BBS update."
Microsoft says, sometimes this new tools are working properly, in other words, if it prompts you to replace batteries could be your Dell Latitude E5400 battery has really want to hang, but clearly the misstatement risk is too high.

We see no need for the introduction of lithium-ion batteries in hybrid vehicles to move
There is no doubt that the nickel-metal hydride energy storage system has proven in many applications. Despite this great success, expect Johnson Controls-Saft a similar development as has taken place in portable batteries in recent years. Attractive technical features ensure that displaced are increasingly nickel-metal hydride of lithium-ion Dell Studio 1537 battery.
Current concerns about the lithium-ion technology are the result of some critical incidents involving lithium-ion portable batteries. In this context, some important facts often overlooked or not adequately considered. The few incidents with a portable battery cells are indeed spectacular and always seem to represent the headlines, but not the whole picture. The failure rate of lithium-ion batteries is well below 1 ppm.
Its motor vehicle used lithium-ion technology is crucial significantly from the Dell Latitude E6500 battery in the device area related. While portable batteries are optimized mainly toward ever-higher energy densities, which can lead to greater security risks, lithium-ion batteries for cars are developed specifically in the direction of high performance, robustness and security. Undoubtedly, lithium-ion batteries for their preparation and handling much more sophisticated products than nickel-metal hydride and lead acid batteries. However, there is a proven technology for the production and operation of these batteries. Especially the subject of security in the overall design of the Dell xps m1330 battery system on multiple levels (cell, battery, control software) as shown redundant.
Johnson Controls-Saft is a manufacturer of two new battery systems, nickel metal hydride and lithium ion, a clear preference in favor of lithium-ion batteries. The in-house available technology has reached a level of maturity that we as an opportunity for us and our customers. We see no need for the introduction of lithium-ion batteries in hybrid vehicles to move and to bridge this period, with nickel-metal hydride batteries. The first vehicles with lithium-ion Dell Inspiron 6400 battery from our company are already in 2009 in hybrid vehicles appear on the market. Johnson Controls-SAFT in February 2008, a lithium-ion battery production for automotive applications in Nersac (France) commissioned.

Electric vehicles with range extender
The automotive industry is now more than ever before the challenge of making mobility sustainable world, affordable and environmentally sound. The CO2 debate has been the use of secondary energy source “electricity” is set for the individual at the center of discussion. This play not only with purely electric vehicles, the so-called plug-in hybrids, which have a rechargeable Dell Studio 1735 battery from the power grid and use it as both an all-electric drive and an internal combustion engine path, then a special role.
The battery technology is on these concepts, the key element. There are great efforts to develop suitable vehicle battery systems. For the foreseeable future, the lithium-ion technology is to be preferred, even if there are still technical limitations that must be sent to expand. This includes in particular the behavior of the Dell xps m1730 battery to provide at extreme ambient temperatures, a limited load capacity or a limited power for driving, heating or cooling the passenger compartment.
An efficient solution for the control of such restrictions may take the form of a so-called range extender module (SEM). SEMs are small, usually combustion engine-driven generators, which are used only when needed. For a virtually independent from the Dell Latitude E6500 battery range is possible, which will affect the acceptance of electric vehicles at the customer crucial.
The properties of these modules to the specific operating conditions such as significantly higher NVH requirements, less critical requirements for start time and dynamics in the operation or reduced life cycle requirements to adapt. The analysis of this specific requirement profile is unconventional solutions, such as an external combustion or low-vibration, low space-rotary engines to the list of considered alternative solutions.
After almost one year trial period in FEV LiIon battery electric vehicle with REM provides important findings that confirm the benefits of an SEM approach. The Wankel engine used allows a package of REM in the space of the former tanks, the volume was reduced to twelve liters, and features a excellent NVH characteristics. After extensive dynamometer and road testing the vehicle with REM was approved for road traffic.
In addition to the NVH adjustment and the everyday use the designers did not ignore the system cost in its sights. Since the cost of a REM about 1-2 kWh Li-ion battery capacity corresponding to the overall costs compared to a pure electric vehicle can be reduced significantly. In the present vehicle would reduce the costs of the “system” by the electric drive REM by about 30%.

Laptop battery must be replaced occasionally
One advantage of laptops over computers is that you can transport it and use at any location of the battery. But a prerequisite for this is that you have a functional battery.
As laptops have batteries, you can use it basically for a certain period of time without electricity. Once the Dell xps m1730 battery is charged on electricity, it holds for a limited time. Many people appreciate it, to sit with his laptop in the garden in the park or in nature. Or they take him to a cafe to work there. In such places is not always a power supply is available, so it is advantageous if the laptop runs by battery.
But often it is so that the Dell XPS M1530 battery quickly loses functionality. Thus, the time in which one can use the laptop without power, shorter and shorter. Sometime it pays no more to take the laptop. The reason is that the batteries have a relatively high wear. In the long run they have to on energy, so that if one wants to use the laptop fully, often get the new battery must.
Nevertheless, there are several ways to extend the shelf life of the Dell Inspiron 1501 battery. You should check in advance how to best conserve battery power. This will save you money, since the battery must be replaced less than a thoughtless wear. It is not recommended, for example, the laptop constantly connected to the power to make, since it is harmful when a full battery is further charged. Instead, he was to be discharged to a certain level and then reconnect it. An alternative for people who always have their laptops are at the same place, is to take out the battery and run the computer only on electricity. The removed battery to store it in the refrigerator is best because it is protected in cold temperature at best. If you use the laptop without the battery, however, should be ensured that the cable can not be accidentally pulled. Because if you educate the computer suddenly the electricity, this has at least as problematic as the effects of wear on the Dell Studio 1535 battery.
But even these precautions can not prevent you replace the battery at some point, if you value the electroless usability of the computer. A spare battery can be purchased from the manufacturer or at other computer stores. It is important that you have obtained the correct battery for the corresponding computer model.
Kamenz: Saxon Centre for the battery technology of the future
The differences are enormous at first glanceIn the USA, the hyped battery technology specialist A123 Systems just managed the IPO, and benefits from substantial government support. The companies from the electric mobility is a world-known and well perceived. Quite different is a joint venture of large corporations, which in the quiet town of Saxony, with its 17 500 inhabitants Kamenz is based.
The Li-Tec Battery announced last September, in the race to have made the best Dell XPS M1530 battery solution for the automotive industry in the future very far. From 2011 Kamenz, several million cells are produced in batches – Li-Tec Battery in Europe is the first manufacturer of mass performance lithium-ion battery cells with ceramic technology.
Li-Tec is hidden behind a joint subsidiary of Evonik Industries AG and Daimler AGThat researches in a consortium with BASF, Bosch, STEAG Saar Energie and Volkswagen and brings the technology to maturity. Modestly takes support from the Ministry of Education: 60 million € is peanuts compared to what has been collected, for example, A123 Systems.
Nevertheless: The technology of the quiet, confident 50 kilometers northwest of Dresden, located Kamenz. Thus, the production-ready High-tech battery cell Li-Tec other products, superior claims to a substantial extent. Its leading position reaches the cell Li-Tec through the use of the unique ceramic storage technology, the Li-Tec has recently under the brand name has CERIO bundled.
CERIO based on a special combination of ceramic materials and high molecular ion conductors. This battery cells set the highest standards in terms of cycle life, power output and not least on security. Together with the compact design of the Dell Inspiron 1501 battery allows for high energy density and low weight is achieved. CERIO ? technology is the core of the ceramic separator SEPARION.
In the future-oriented partnership combines the chemical expertise of Evonik with the vehicle competence of Daimler. Li-Tec will provide future not only Dell xps m1730 battery cells for Mercedes-Benz Cars, but is also open to other Anbieter.Gesch?ftsführer Dr.
Andreas Gutsch is pleased with the high demand for the technology of Li-Tec:
Which technology will ultimately be the market leader, will prove the future. The opportunities for the company Kamenzer Li-Tec Battery seem to be big … In addition to Li-Tec is sitting with the German Accumotive GmbH & Co. KG Incidentally, another joint venture between Evonik and Daimler (90 percent) in Kamenz – the hub of European Dell Latitude E6500 battery technology.

Windows 7 kurios – battery warning for laptop is a feature not a bug!
Worldwide complain Windows 7 – user that indicates Windows 7 on battery issues. More specifically, is a warning note that the Dell Inspiron 1501 battery is charged or even lack of power had changed (although this is obviously not the case according to the display). To the complaints, Microsoft has indeed reacted and investigated this issue thoroughly within reason.
But the result of this investigation for the user less likely to facilitate rather than be a slap in the face. Because Microsoft recognizes not mean that it is a bug in the operating system of trade – this concession can not afford to recent reports of success on market share of Windows 7 of course – but insisting instead that it is these warnings rather an internal Feature trade.
This finding was a collaboration with various manufacturers of notebooks previous, which had shown that all of a predefined boundary was not reached, the Windows 7 cause in the episode, to recommend to the user a Dell Vostro 1510 battery replacement.
According to Windows chief Steven Sinofsky had it essentially affected notebooks that are older than 1 1 / 2 years. That this was the case not quite, I unfortunately have to see for yourself, because even shows up on my netbook, which is just one less than six months old, and again under different circumstances, such a warning ..
Although known for a long time that the Dell Latitude E6500 battery of notebooks and netbooks lose gradually through the utilization and memory effects become more and more power, but Windows 7 is really overdoing. Microsoft still stirs from. The limit range of the Dell Studio 1537 battery is possibly also earlier (in the case: under Windows XP) was not reached. However, as with Windows XP, this function was not integrated, this state could eventually not be displayed. It follows that from the perspective of the Redmond software company and not a fault of the new operating system, but rather an intelligent feature. So much for the service availability of Microsoft.
For the future: the warning appears usually have to wait for when the battery is to provide only about 40 percent of its original term capable …
Battery-inventors, the country needs
For the electric car are professionals asked
Even the standard introduction of electric cars future music – but now is not only inspires the imagination of politicians and industry leaders, but also offers new career opportunities for graduates.
This is especially true for battery research. Anyone here expert, so electric chemist who is currently one of the most sought-after professions in general. For so far the series production of electric cars fails because of the lack of coverage, because the Dell Studio 1537 battery still have enough storage capacity.
In Germany there is no single production facility for advanced battery systems, lithium-ion technology, which are already used in mobile phone batteries or laptop computers. Knowledge is scarce.
The only represented in Germany Dell Inspiron 1501 battery producer Varta made, based on the old nickel-cadmium technology is not suitable for electric cars. So far, employers and funding agencies were lacking in this area. But this is changing now. Thus, the Technical University of Munich has recently set a research and teaching focus around the Dell xps m1210 battery technology and called for a number of new professorships and programs to life. The same happened in other universities: two from the Ministry of Education funded networks have been prescribed for nearly a dozen universities in the research at the battery of the future. Besides electric chemists are among the research organizations researcher with a focus on physical chemistry and iron researchers as well as mechanical engineers, electrical engineers and computer scientists.
Apart from the electric mobility Dell Latitude E6500 battery research also provides logistical and information technology perspective new fields. Because the electric cars also require a comprehensive infrastructure of charging points and charging systems. Here, too, just create new jobs, for example in the energy companies.

Lithium-ion battery is not the same lithium-ion battery
Until recently, mobile devices with strong currents need – such as power tools and medical equipment – rely on nickel-cadmium and nickel metal hydride batteries. With advances in lithium-based batteries as they apply in relation to the nickel-based batteries in terms of load capacity to be equivalent or even better. It is expected that lithium-based batteries will prevail in these high-current applications.
The cobalt-based lithium-ion was first introduced in 1991 by Sony. Because of their high energy density, continued this battery chemistry by very quickly. The spinel-based lithium-ion had a slower start, probably because of its lower energy density. Upon his release in 1996 called for the operator, especially longer terms. Since many mobile devices today require high current, lithium is now at the front and is enjoying strong demand. This has become even so large that the manufacturers of these batteries can not meet her. Therefore, there is so little advertising for that Dell Latitude D400 battery
type. E-One Moli Energy (Canada) is a leading manufacturer of spinel lithium-ion batteries of cylindrical shape. The company has specialized in the cell styles 18650 and 26700th Other major producers of spinel lithium-ion batteries are Sanyo, Panasonic and Sony.
Sony focuses on the design with nickel, cobalt and manganese (NKM). Nickel, cobalt and manganese are Mehrmetalloxid as the crystalline structure of the cathode to the lithium is added. Within this type of battery, the Dell xps m1730 battery manufacturers offer a wide range of high energy density or high load capacity. These two properties can not be readily combined in a battery, but it must always be a trade. NKM can to 4.10 V / cell load, 100 mV less than cobalt and spinel-based lithium-types. A change in battery chemistry in order to raise the voltage to 4.20 V / cell would, but to a higher capacity, but also lead to a shortening of the cycle life. Instead of the normal 800 cycles to be achieved in a laboratory environment, the cycle number would drop to about 300.
Cathode with phosphate nanoparticles
The newest member of the family, the A123 lithium-ion system, adds to the nano-phosphate to the cathode. Although the manufacturer nor the metal used to keep secret, it is generally accepted that it is iron. The manufacturer specifies that this guy has in all commercially available lithium-ion battery has the highest energy density. The cell can be continuously at a current strength of 35 C discharged to zero (discharge) and tolerates Entladestromimpulse of up to 100 C. The phosphate-based battery has a nominal voltage of about 3.25 V / cell. The landing threshold voltage is at 3.60 V. This cell voltage is much lower than 4,20 V / cell of the cobalt-based lithium-ion batteries – the A123 system needs an appropriate charger. For this Dell Latitude E6400 battery type is a large demand is expected. The company A123 Systems was founded in 2001, among others, Motorola, Qualcomm and MIT was founded.
A mess of tension
Only about ten years, the nominal voltage of a lithium ion cell 3.60 V. An appropriate value because it corresponds to the nominal voltage of three cells connected in series, nickel (1.2 V). A higher cell voltage of Li-Ion brings a handsome Wh value on paper and therefore a marketing advantage with it, the device manufacturer, the cells still see as a 3.60-V cells.
The rated voltage of a lithium-ion batteries is determined by one with about 4,20 V fully charged Dell Latitude E5500 battery is discharged with a current of 0.5 C to 3.00 V, while the average voltage is measured. Due to lower internal resistance is the average voltage of a spinel Li-Ion batteries are higher than that of a cobalt-based batteries. Pure spinel has the lowest internal resistance and a rated voltage of 3.80 V / cell. The exception again is the phosphate-based lithium battery. This type differs most from conventional lithium-ion type.
What to do with sucking out batteries?
Many know the problem is that the notebook battery much too quickly loses its effectiveness. But what is this phenomenon and what can I do about it?
The biggest mistake you commit to the notebook user that does not complete loading and unloading of the Dell Latitude E6500 battery. Here, the partial discharge cause formation of a slag within the battery and causes slagged these areas are no longer usable. Since the battery is often invited back, although this still has capacity, engender the loading cycles are not completely. Each battery lasts only a certain number of charge cycles, which should be fully exploited due to this.
Another, often underestimated factor is the weather. Especially Notebook Batteries are very temperature sensitive and therefore should never be exposed to high or low temperatures. You should place the battery in the summer, therefore, never in the sun and protect it from cold in winter influences, so do not leave in the car or put on the windowsill.
Furthermore, the user should remove the laptop battery power during continuous operation of the device. The reason for this is that the Dell xps m1730 battery
even when not in use, absorbs heat from the notebook, which will also adversely impact the battery life. It should here be noted, however, according to various notebook manufacturers are that the battery has a charge in front of the removal of about 40%.
All these preventive measures are in compliance with their very helpful to share with the increased battery life. But what if the Dell Vostro 1510 battery has already lost its power?
If the capacity gone once lost it is very difficult to resuscitate the battery. Proposals are here by short-circuiting the battery over discharging by lightbulb to the use of professional chargers.
By the method of short-circuiting I would advise any user, for in the first forfeit in case of any warranty on the device and second is an explosion.
The discharging of the battery at the light bulb is a little older but apparently working his way back to breathe some life battery. By repeated loading and unloading of the battery with light bulb and battery charger can be reached that slagged areas can be used again also. There is no guarantee this is not, however, the effectiveness of this method varies from model to model.
The safest but also most complicated and most expensive method is to use a professional charger. However, these are in most cases very expensive and also quite bulky. With this device you can easily complete the battery load and unload. The carrying of such a device is extremely impractical.
If the Dell Latitude E5400 battery is too late to save one only one option: A new battery must be her. We asked here about the price falls down a fast his jaw, as this may also crack the 200 € mark. There are Resellers for counterfeit laptop batteries, Which can sweeten the purchase of a new battery a bit. In my opinion, is the best option is for the extensive use of the direct purchase of a laptop replacement batteries. So one is always used appropriately in the situation and its battery in the case of a failure also well prepared. Watch it before you buy a notebook that it has a Lithium-ion battery features, the memory is completely negligible effect, for these models it can not fall victim to.

Five ways of selecting laptop battery
General international line of laptop battery brand products will provide a CD-ROM that came with the battery management tools, such as the ThinkPad's Thinkpad Configuration, SONY's PowerPanel so. This is my software we can use this tool to read the intelligent control chip inside the battery to find out the battery design capacity, actual capacity and other information.
However, these tools are only useful for original battery, and I recommend BatteryMon software, the parameters of the battery can be intuitive display. BatteryMon read the information board battery PCM, but for the core battery as to keep the original circuit, so for the core battery BatteryMon "eyes" still is an original battery. In this regard, we can according to the battery capacity information to select, in general, for the actual capacity of the battery core is often not consistent with the design capacity.
2. To see the appearance of selected
We buy laptop batteries at the time to carefully look at the battery shell process is good, edge is working fine, print fonts are clear, usually fake details and there was a clear distinction between genuine. If convenient, you can use BatteryMon test battery manufacturer and part number. Here suggest that you buy a second battery at the time were careful to bring Original battery.
3. By asking selected odor
If your sense of smell, then you can try to sniff odor. Brand new original battery and compatible batteries are generally factory of electronic products unique flavor (similar to sandalwood, I believe that this is a plastic smell more accurate) of this smell of perfume can be no ordinary imitation. The refurbished battery, repeated use of counterfeit batteries have no odor at all because, for the core battery is to use strong glue bonded, there will be irritating odor.
4. Dian weight of the selected
Very often, the weight and quality laptop battery is directly proportional to the time of purchase can be hand Diandian weight, lighter than the original battery, be wary! Of course, sometimes this approach is not very accurate, such as nickel-metal hydride batteries use the old batteries when.
5. Under the warranty to identify
If the warranty time is not more than six months or six months we should be careful, because the batteries are consumables, the number of charge is constant, with a little time, poor-quality batteries generally occurs in endurance performance after two months dropped rapidly, and can not charge and so on. It can be said from the time the warranty can determine the age of the battery, at least to judge the age of the batteries.
I have bought a dell inspiron b130 notebook to my sisiter.The quality is great.I have use it for a long time.The battery also very good.
Laptop battery repair method
Two concrete steps to fix: 1. Settings (if necessary repair to the best laptop battery (batteries not aging), this is the most important place. Therefore, we should pay attention.) Let notebook battery running really finished after this did not interfere with the remaining power, will revise its laptop battery itself, the minimum charge and discharge and charge curves of the synchronization between the. 2. Charge and discharge specific steps Description: Set in After doing the above, you filled up in accordance with the principle of complete charge and discharge the battery, and just bought a laptop battery recall that the activation step back, and my last laptop battery is fully charged Raiders discharge it? In accordance with the principle of charging and discharging the battery back and forth three times, you can shift the curve to the battery to correct the fix coming. Note: When must let the battery charge is full, the best way is to shut down a full 12 hours or at night, and then unplug the power supply discharge until the computer automatically fall off. This back and forth at least two cycles.
I have bought a acer aspire one laptop in a few years ago.The laptop battery have broken last moth.Then I repaired in this way.It's all right now.I hope my blog can help you.

How to calibrate laptop battery capacity
Laptop battery is a necessary spare parts. The use and charging, will face the problem of declining battery capacity, which is calibrated the battery problem. Well, there is no need to calibrate the battery, how calibrate the battery?
The answer is yes. Because of this decline was not due to cell aging and is therefore appropriate to make this part of the calibration can restore the lost capacity. But the battery should be regularly calibrated, such as 1 to 2 months time.
Such as Compaq and IBM laptop's own power management in BIOS or a program to provide a battery calibration, so the two brands using friends can according to the prompts. For those who do not provide this feature the brand's users according to the following steps.
1. The screen saver is set to "None."
2. In the Windows Power Management power scheme will be set to "always open" and shut down equipment related to the following menu all set to "Never."
3. The alarm tab will be "insufficient power warning" is set to 10 percent, the operation is set to "do nothing"; will be "a serious power shortage alert," set to 3%, operating as a "stand-by."
4. The screen brightness set to maximum.
5. Confirm that all the windows closed, and save all the data before the work.
6. Check that the battery charge after more than 80%, unplug the power and all external devices, then if the screen automatically reduces brightness, then turn it hit the brightest.
OK, you can go to sleep, the discharge end of the notebook will automatically shut down after. After the power plug, so that notebook charge. Attention must be so completely full before turning on power, and then return to the power scheme settings before calibration.
The aim is to continuous low current discharge batteries, which discharge state in our daily use is impossible to achieve, as the normal state we may make various changes in current operations up and down.
IBM, SONY machine can detect that the battery capacity before and after the change, other machines can download a program called batterymon to see, you will find, little by little to restore capacity in the. However, here to recall that, if your battery is caused by excessive use of aging, Na this ad-hoc method is also not solve the problem of little use Du no.
This method is also recommended that a friend just to use the new machine hand: General Li battery before use in accordance with this method is best for 2 to 3 times the maximum possible in order to best performance of the battery into position.
A major breakthrough in laptop batteries

Apple admitted that some laptop batteries are charged will be expansion and deformation fault
Li-ion battery for iPod suspected quality problems caused by "explosion door" crisis was not resolved, but also cropped up more than laptop battery expansion events; just released to solve performance problems of the software upgrade the battery program, named by another notebook design flaw exists. Apple has to controversy, the flagship product ipod and laptop computer battery quality and widely questioned. In response, the industry told the "Daily Economic News" interview analysis, said a short time a series of similar quality problems, will likely lead to consumer crisis of confidence on the Apple brand.
April 27, Apple publicly admitted some of its MacBook and MacBookPro laptop battery charge failure may exist, and issued an upgrade program to improve battery performance. Although the Apple side stressed that the laptop battery charge arising from failure, "there is no security risk, the user can continue to use these batteries," but according to British media reports, MacBook battery issue than Apple's open to a serious extent.
It is understood that, as of now, MacBook users have reported numerous cell expansion events, the problem comes from 17-inch MacBookPro. As a system administrator, according to one user describes, his research lab ordered 4 sets of 17-inch, using CoreDuo processors MacBookPro, of which 3 units are in use during the expansion deformation of the battery occurred. He said, MacBookPro expansion of precursor of the battery occurred, MacBookPro when using battery power random shutdown, and pressure by the expansion of the battery, sometimes manifested as decreased sensitivity trackpad.
As MacBookPro battery, all in the foreign expansion, so there are problems specific type of products is still unknown. The source told reporters that such a battery can be replaced free of charge, but there are potential hazards such as heat explosion, and that the software fixes this problem can not be solved by. In response, Apple's head of public relations in China are maintained, Apple has confirmed that there is no security risk battery failure, consumers can continue to use, and maintenance plan that the battery is not the same as the previous battery recall program.
The source said that in today's digital audio player market, Apple's share of the market, whether Samsung, Sony, or innovation, Microsoft, can not hold a candle. Prior to rivals also did not pose a serious challenge to Apple. But the iPod "blast door" after the incident, another series of laptop batteries burst expansion, design flaws and other issues, Apple's product quality will inevitably suffer some of the wavering of suspected users, and even Apple's brand loyal "fans" will also quality of products already have doubts. Coupled with Apple's side is not yet on the iPod "explosive" issue and a public response notebook design flaw, nor take any substantive measures. Apple brand that consumers trust crisis, "may be only a matter of time."
How laptop battery explosion
Foreign PC secure site to allow laptop users to fully understand the danger of explosion notebook lithium batteries, by using a well-made laptop battery laptop lithium batteries for a simulated explosion video.
This video shows detailed notebook battery explosion in the number of process: The first battery explosion, smoke; lead to the second battery chain reaction, explosion, fire; residual battery exploded violently burning - in the process , notebook high ambient temperature, and combustion for the chemical, electronic combustion, laptop notebook users must stay away from the accident, avoid water and other conductive material put out the first time, where possible, make a fire.In addition, on the side of the backup battery will produce violent explosions due to high temperatures, chemical reactions, and even burn.i have ever seen dell laptop battery explods in the website.it's terrible.and the laptop battery model is D410.
If your laptop battery recall and not to themselves and their families as a trifling matter of life and property must be replaced in order to avoid similar incidents in the video.
True and false laptop battery
Notebook of daily use, for various reasons, we often need to buy a second battery, the original notebook battery frequently need a thousand dollars, for the majority does no document Bu Xiao Ren's Touzi. If you accidentally encounter the unscrupulous businessmen, who buy counterfeit batteries, that a big loser.
Recently appeared on the market a number of counterfeit, IBM batteries, such batteries generally low cost, if consumers choose to buy inadvertently, not only suffered economic loss, and from security point of view, leave the battery poor quality and can not guarantee the safety of users.i have ever bought a false ibm thinkpad z60t battery
Voltage unbalance control is the battery for the ThinkPad computer assembly plant in the most important design element, but leave the battery manufacturers are a lack of consideration in this regard. Use fake batteries, the most serious may result in burn, fire or explosion accidents.
To make everyone in the purchase IBM's battery, to distinguish the authenticity, to avoid unnecessary losses, we following the "around," all-round introduction to IBM battery and false distinction between genuine battery.
Labeling (1)
True and false
1. Leave the battery label products digital bar code option is inconsistent.
2. Fake batteries do not have + / - mark.
3. IBM battery before the four digits of the digital section number for the FX0B the false battery 1Z46.

how to extend laptop battery life
Laptop battery really have a life, and its longevity directly affected by the charge and discharge times. If you are always installed batteries in the notebook computer , and disconnect the power shutdown mode, the battery will slowly discharge. When you connect an external power source, the battery will automatically begin charging. This constantly repeated charge and discharge, will significantly shorten the battery's useful life. Therefore, we recommend: When you use the laptop battery as far as possible every time to power the basic exhaust (less than 5%) and then plug in an external power supply for charging, and charging time should be controlled within 12 hours, and this is is the best way to avoid the memory effect. (In fact, this habit also applies to other electronic equipment batteries, including lithium ion batteries and nickel-hydrogen batteries.
If you use an external power supply in a fixed location for a long time, the best able to remove the laptop battery to maximize battery life. However, we should note that, even if the battery for long time also try to charge and discharge per month of their time, to ensure that their activity will not lost. In addition, if your notebook PC with a backup battery, then when it also needs care CAUTION: The battery backup for long time and does not charge excessive discharge phenomenon, please do not run out of battery power state of its long-term storage (half as much as possible about the remaining power). Of course, you should at least once every six months of their discharge and maintenance to maintain its optimum performance.
There has been significant performance degradation for the battery, you can use the battery calibration method to carry on the "Resurrection." Unfortunately, only a handful of laptop batteries to provide a correction function, for most uses, you need to do this manually. Concrete steps are as follows:
First, the abolition of notebook power-saving power management features, such as disabling the screensaver, the power scheme set to "always open" to "power shortage alert," the corresponding operation is set to "no action";
Retain only when "a serious power shortage alert," when the "standby" operation, in order to ensure that the system can be normal standby;
Then the screen brightness set to maximum, and save all data, close all of the program window;
After charging, unplug the power supply, so that a sustained small notebook current discharge;
Discharge end of the notebook will automatically be turned off, then plug in the power of the laptop for charging.
Repeat the above steps 2 to 3 times, you can save the batteries which has begun aging.
