How to test the true extent of battery capacity

How to test the true extent of battery capacity

How to test the true extent of mobile phone battery Toshiba PA3331U-1BRS Battery capacity?


Lithium battery charging method is to limit pressure cross-flow mode, the general charge current are set at 0.2C.


C charge and discharge current tends to be used as a reference, C is the corresponding battery capacity values. MA, said battery capacity tends to be used, such as the L600 battery Toshiba PA3166U-1BRS Battery capacity of 1800mAh, the corresponding C is 1800mA. 0.2C is equivalent to 240mA.


Li-ion battery charge current is generally set at 0.2C, according to this principle, we can charge the battery time to calculate the approximate capacity of mobile phone batteries.


To L600, for example, to calculate the L600 battery Toshiba PA3191U-1BRS Battery capacity: The battery is marked 1800 milliamperes, according to "General Li-ion battery charge current set at 0.2C" calculated, 0.2 × 1800 = 360, the charging time from the L600 run, L600 the battery is full time for nearly 5 hours, 360 × 5 = 1800. This basic calculation out the cell phone battery capacity.


The machine can be seen the capacity of the battery capacity and is in line with annotations.


Many cottage machines, the battery capacity of the target are very large, and some shockingly big, full of quick charging time, and a use of two days of no electricity. In this way, we can easily determine the approximate battery Toshiba PA3285U-1BRS Battery capacity.

XP Useful tips: extending battery life

In the process of using a laptop computer, there is an important issue is battery Toshiba PA3395U-1BRS Battery life. In order to extend battery life a lot of computer manufacturers to design sophisticated programs to reduce as much as possible the use of hardware power, such as Intel's CPU automatically down-conversion technology.

But you know through the Windows XP system settings can also be reasonable to reduce the power consumption of notebook PCs do? In the Windows XP boot Toshiba PA3399U-1BRS Battery process, load a lot less than we might use the process and procedures. This makes the computer's start-up time extended in order to use too much power.


And notebook computer does not correctly distinguish lies in the different power modes need to activate the system processes and procedures, so we need a way to set the user to configure the table to achieve our objective. In the user account to add a new Toshiba PA3084U-1BRS Battery account, and then log on using the new account name and then "Start" menu items do not need to start to delete. This can increase the boot speed.


Later, when you use an external power supply when using the original account login system, using the built-in batteries with the new account sign-on system.


Finally, there is little to remind that in order to be more smooth transfer between the two accounts, during the installation process when the option "Allow everyone to use," and then the two Toshiba PA3098U-1BRS Battery accounts of the "My Documents" point to the same folder ( How See: XP Practical Skills: Moving "My Documents").

Scientists: the first to develop a urine-powered paper battery

Physicists in Singapore has announced that developed the first laptop battery urine-powered paper to the battery. They said that this credit card-sized battery can be used to power low-cost medical testing tools, and even used as a cell phone in case of emergency power supply.


Urine tests can find diseases, while the new battery will enable the test urine sample can also supply diagnostic equipment. Singapore Institute of Bioengineering and Nanotechnology of the Ki Bang Lee, said: "We are working to develop low-cost testing for the disease, the credit card-sized disposable biochip. Our battery can be easily integrated into such devices, in the urine and the like fluid or blood and other biological fluids to provide current contact. "


During the current bio-chip IBM 92P1102 Battery diagnostic tests, the need for external sensors (eg laser scanner) or an external power supply (such as conventional batteries). The Lee's sensor and battery technology will be installed in a plastic chip. Battery by a layer of soaked filter paper in copper chloride composition of this layer of filter paper clip in between the magnesium and copper strips. The urine of salt caused a chemical reaction, magnesium metal layer as the anode to lose e-, copper and copper chloride as the cathode to release electrons. Lee said that the urine-powered battery only 0.2 milliliters of urine can provide about 1.5 volts, the power of 1.5 milliwatts of electricity. If you activate the battery for the first time to run 15 hours later by adding a second drop of urine, the urine can be issued to add more IBM 08K8196 Battery power. The battery is currently available in a one-time equipment, you also can not be used as a laptop or iPod power supply.

Now the battery in the factory before they had been activated (if you are buying a hoarding goods, time, hoarding, and require re-activation). So, no need to bought off enough to come back in the first three minor more than 12 hours


Battery calibration method:


When the battery capacity DELL 08K8194 Battery dropped a lot of sense to use significantly less time and can be used when the battery calibration, the official statement is the best 3 months corrected time.


1. Press F2 to enter BIOS


2. Chose to enter the menu POWER


3. Select START BATTERY CALIBRATION later, you are prompted, then connect the power adapter in order to facilitate machine-to-charge the battery.


4. When the screen appears, the following prompt, please remove the power adapter. And wait for the machine automatically shut down to complete discharge.


PLEASE REMOVE AC ADAPTER


5. To be connected to the adapter is turned off, the charge to the charging indicator light is off, that is the completion of the battery IBM 92P1087 Batterycalibration

South Korea has developed the world's most efficient battery is two times the existing battery Author: Toshio Baba,

Local Time this week, three South Korean IBM 08K8199 Battery scientists say they have developed a new prototype flexible solar cells. According to scientists, the newly developed flexible solar cells is now the world's most efficient batteries.


According to Electronics and Telecommunications Research Institute (ETRI) development team leader Ryu Gwang-seon said, it is noteworthy that the new flexible solar cell manufacturing cost is very low, after testing with traditional silicon-based solar cells than it is produce the most efficient current.


Gwang-seon said in a telephone IBM 92P1073 Battery different from the traditional silicon-based solar cells, scientists have newly developed products to titanium oxide, pigments, and the electrolyte layer sandwiched between thin plastic and stainless steel plating to protect. Scientists said the new solar cell thickness of only 0.4 mm, which convert solar energy into electrical energy efficiency of existing solar cells is almost twice.


Gwang-seon said: "We, including the United States and Japan, including six countries submitted a document, register a new solar energy technology is being patented. End of this year, we plan to transfer this technology to the enterprise, making it as soon as possible commercialization." He added that the new solar cell has soft features, this product will be used for future mobile phones and laptop battery computers, it is relatively resistant to impact, mounted on glass can be used in the automotive industry.


Gwang-seon said the new flexible solar cells can be attached to the tie on consumers, will come from the sun's energy into a current post for portable electronic devices. He said that his development team after a four-year study to develop a new solar cells.


He refused to disclose the details of investing in the technology, but cites the investment plan is now underway.


Electronics and Telecommunications IBM 92P1077 Battery Research Institute, said the new product development is the South Korean government to seek national information technology industry, new revenue sources part of the plan. The Academy said in a statement, in the global solar cell market is expected to market size in 2010 will reach 10 billion U.S. dollars.

San Francisco, Apple Computer Inc. announced a recall of 1.8 million notebook computer batteries.

In various computer makers to recall details of the brand has been providing for the recall of specific measures for consumers.


Lenovo Group announced on its website specifically IBM ThinkPad A20M Battery recall the recall involves the specific methods and models, including models include: In February 2005 ~ September 2006 to buy the following notebook computer models and registered consumers of notebook batteries may be the scope of the recall, R Series (R51e, R52, R60, R60e); T Series (T43, T43p, T60); X Series (X60, X60s). Lenovo Group, said that in February 2005 to September 2006 period for the purchase of these two brand laptop users, in identifying their own use of the laptop battery has been recalled, just bring warranty card, batteries, and notebook , to the designated repair station can be replaced free of charge a new battery.


The Zhu said that Lenovo now also launched a "free door for the battery" measures. Consumers only need to make sure your computer to recall the list, telephone notification Lenovo branches throughout the country and service agencies can be. "Moreover, with some companies have limited free replacement in March is different from Lenovo's replacement for an indefinite IBM ThinkPad A20 Battery period."


Dell said the problem of these batteries was April 1, 2004 to July 2006 and 18 between the delivery. On its Web site, Dell computer models listed in the recall. Dell (China) said to this reporter, Dell's first through e-mail and telephone, etc. and have accurate contact information, the user directly linked to the same time, also offers a special recall web sites to provide multiple languages including Chinese version, "Users simply enter the serial number of the battery can be easily carried out online inquiry."


Dell said the "11" period, Dell's service department IBM 02K7054 Battery through the 800 phone and e-mail address for the customer the battery recall problem. "Recognizing that the user belongs to recall the scope of the battery, we will soon deliver a new battery free of charge for the user and retrieve the old batteries."


The company is not involved in the battery recall, attitudes seem interesting.


Acer recalls the incident did not happen, its public relations department said that the Acer notebooks, some models use Sony batteries, "but Sony made available to the Acer's battery is different from other manufacturers (this paper Sony's has already been confirmed), we did not happen in the market to other manufacturers similar circumstances. we are very mindful of any related events, and with Sony to maintain close contact, concern the progress of the whole situation. "


At present, the same aloof from the IBM 02K6928 Battery Hewlett-Packard a more cautious approach than the Acer, the reporter repeated contact with the company, the company, due to excessive heat has not yet received the incident report, Hewlett-Packard currently no recall program. On the other hand, "HP is doing an active investigation of global scale and, if credible scientific report shows that the battery problems, Hewlett-Packard will soon be recalling their products."


Sony Corporation said that the batteries used in HP's core (battery cell) without recall.


But for consumers, "total recall after the explosion" is obviously not a perfect answer. So, for enterprises, how can we take preventive measures? How to be more active and effective public safety response to a similar incident?


Recall Mechanism


"Since there has not been preceded by similar incidents, we did not specifically recall system." Lenovo Chinese Foreign Ministry spokesman Zhu said, "But when you think from top to bottom, have attached great importance to such an event, for example, in this recall the incident, from the Group's global regional markets, Lenovo have set up a dedicated management IBM ThinkPad R32 Battery team, from the CEO to the global regions worldwide CEO, have been involved in customer-oriented problem-solving in the past. "


I understand that recall the incident took place already in the global IT industry, notebook computers, desktop computers, digital cameras, motherboards, etc. have appeared to recall a precedent.


However, according to a press surveys, including Lenovo, HP, Dell, Apple, Fujitsu, Acer, HP, etc., the company, although the services have an effective solution, but there is no mechanism for a complete recall.


In the domestic market, the reporter had an interview with IT to recall the topic of Tsinghua Tongfang, Founder Technology and other domestic manufacturers, the reply was that the company has not experienced product recall, but also the absence of complete recall mechanism.


"Product recalls after problems were chosen, which is a good thing, is IT industry forward." Secretary-General of the Chinese Institute of Electronics Ru Lin said, "This recall incident, the laptop battery so small parts are significant, this Note: In the international context of the IT industry IBM ThinkPad R40 Battery chain, the whole industry is a whole, one aspect of problem, will lead the entire industry, one aspect of doing a good job will affect the overall development. "


Ru Lin a strong appeal, "the recall mechanism for an industry important to the healthy development of China's auto industry has had its own recall of the mechanism, IT industry also should have its own recall of the mechanism!"


As a response to this incident, one of a number of international computer brands have to participate in the development of new battery standards.


In recent years, IT industry, more and more common within the recall of events. It is understood that the industry involved in the recall, there are two, namely, take the initiative to recall and state enterprise mandatory recall. According to Ru-lin, at present China's auto industry is only a "defective vehicle product recall regulations," while IT product that consumers can make reference to only "three guarantees" clause.


However, according to presentations, recall the "three guarantees" a great difference. Recall system means that operators have found that the goods or services provided there are serious deficiencies should take urgent measures to inform consumers, and to recall the product for repair, replacement or destruction. "Three Guarantees" refers to operators to provide goods or services, in accordance with relevant state regulations or the consumer agreed to undertake bag repair, replacement, a caveat vendor's responsibility.


IT recall the face of the lack of a mechanism, China's consumers in the face of the event, such as when the laptop battery IBM 92P1075 Battery recall how should they protect their own interests?


A telephone interview with journalists has been the subject of the China Consumer Association, from the information department of the association has been explained, where a woman is: "China Consumer Association to know laptop battery recall incident, but did not concern." In explaining why it Consumer Association of involving the general interests of consumers not concerned about the laptop battery recalls, the Consumer Association in the Department's lady, said: "not to say that what the community concerns, we will certainly concerned about anything."


Ru-Lin said, and now, the question before us, and replicability, in addition to laptop batteries, other IT products there is no need to recall the problem?


In the current case of imperfect laws can only hope that manufacturers have a sense of social responsibility first, take the initiative to recall their products. However, corporate self-regulation alone will not solve the fundamental problems and develop a set of guiding the recall mechanism, or to urge every IT company to develop their own recall mechanism, an issue that requires the industry to face major problems.


Link 2: Battery out of stock


Battery recall events that may affect this year's laptop battery IBM 08K8197 Battery supply.


It is predicted that by the Sony battery recall events, notebook computer batteries out of stock will be postponed to next year. Analysts said this could affect the sales of notebook computers.


Notebook computer batteries recalled the incident is still ongoing, the information received from Sony, as at present, the number of recalls as high as eight million.


From a global point of view, the Japanese manufacturers to produce Li-ion laptop batteries account for about 70% of the global market, Sony is important to the Japanese notebook computer battery supplier. According to market research of Goldman Sachs (Japan), analysts said Sony's battery business will be affected by this incident "not optimistic" effect.


While many analysts said that the incident could be a related effect: the battery out of stock prices → → global notebook PC shipments were affected by the progress of ... ...


China Taiwan Province, battery suppliers Simplo spokesman for Ding Huimin had publicly affirmed the laptop battery "supply" facts. The company is Dell's another battery laptop battery supplier, Dell recalled about 4.1 million notebook computers manufactured by Sony lithium-ion batteries, the Taiwan S & P Technology has obtained a new Dell about 400,000 battery module of emergency orders.


However, Ding Huimin said, is still not taken place "big panic." Because, apart from Sony, the industry there are a number of China Taiwan Province and Japan, laptop battery supplier.


Others notebook battery suppliers, said a series of actions triggered the recall of notebook computer batteries out of stock situation is likely to continue into next year in June. Moreover, Sony's battery recall is also to other battery suppliers form a "chilling effect", which moves shipments more cautious than ever, this is bound to promote the supply of hard to alleviate the situation temporarily.


At present, the global battery supply is at an obvious shortages. The world's largest manufacturer of lithium-ion batteries can not meet the replacement Sanyo has the necessary orders, while the Samsung-made lithium-ion batteries also appeared in short supply situation. In addition, the use of Sanyo and Sony supply of batteries manufactured lithium battery manufacturers China Taiwan resistant to battery (NEXcell) claimed, and now orders for lithium batteries batteries is very difficult, the company said: "Small quantities of orders still to meet, and large quantities of orders is completely impossible to get the goods. "


Analysts said that as soon as possible to be rid of Sony's consumer notebook battery IBM 08K8198 Battery fear. IDC analyst Richard Shim said that, I think it will affect the consumers from the "desktop - laptop computer" the transition process. According to IDC expects notebook sales to increase by 24%, while the desktop is only 4%.

After the battery problem, Sony demonstrated a positive response to the attitude

After the battery problem, Sony demonstrated IBM 40Y6799 Battery a positive response to the attitude. The notebook computer makers are also held in the global recall of action, but in China, the attitude of each factory is not the same.


Sony's worldwide launch of the funding scheme to replace the battery. Li Xi explained that even the small risk probability, Sony have taken the most secure measures to protect the interests of customers and consumers. Therefore, Sony has taken on a global scale related to battery replacement program to eliminate the recent accident caused by battery overheating concerns. As a part of global action, Sony (China) Co., Ltd. will also actively cooperate with the take appropriate action to ensure that the interests of Chinese consumers and clients the greatest degree of protection.


Sony closely implicated vendors (such as Lenovo, Dell, Apple and other enterprises) and recall the work and take the initiative to start a "for the use of Sony-made lithium-ion battery IBM 40Y6797 Battery cell of a particular notebook computer battery packs worldwide self-replacement program, "and openly recalled 90000 Series VAIO notebook computer batteries.


September 29, Lenovo Group and IBM announced the recall of Sony-manufactured lithium batteries ThinkPad notebook computers, as well as in China, sold part of the range of Lenovo notebook computer lithium-ion batteries, the world's total of 52 million units. Which involved a total of four series, 11 models.


The Dell and Apple are the first batch laptop battery of companies announced the battery recall. August 16, Dell's worldwide recall of 4.1 million batteries, so far, according to Dell China recognized the need to recall about 4.2 million. August 24, Apple recalled 1.8 million to the global issue of batteries.


Recalls an endless stream. October 5, Fuji leads to the global market issues recall 290,000 batteries. October 15, the additional recall of 51000, the total number of recalls has reached 328,000. In addition, Toshiba also recalled 830,000. According to a conservative estimate, as at present, is expected to be the total number of recalled Sony notebook batteries have been more than 8 million.


Fujitsu has said the foreign media, in response to a global recall of Sony's plan to decide on notebook batteries manufactured by Sony to "recall", but Fujitsu in the expression of its Chinese Web site has an interesting statement: "Fujitsu notebook computer does not appears similar to the Dell and Apple computer problems occurred in the Sony battery IBM ThinkPad T60 Battery packs ... ... Fujitsu plans to address some of the implementation of laptop battery pack models 'voluntary replacement' program. "


Fujitsu Limited on why he did not choose "direct recall," the reporter tried to interview the company, but has not been a positive response.


The recall of the above, Sony became the protagonist. In fact, Sony is expected to support only Apple and Dell battery recall program for the full cost of the 200 to 300 billion yen. The Toshiba, Hitachi, Fujitsu and other companies have said may be the battery IBM ThinkPad R60 Battery recall incident to the Sony Corporation claim to compensate for the battery recall incident caused damage to brand image and sales decline in losses.


Faced with this event, Sony's attitude is very positive. Chinese Foreign Ministry spokesman Zhu said, according to Lenovo, Sony, Lenovo will be shared with the recall of batteries from the losses caused to the Lenovo Group.


Sony also admitted that this incident will certainly give Sony a certain amount of economic losses. Li Xi said, "Sony's battery recalls will pay a certain amount of economic IBM ThinkPad A21M Battery costs." October 7, from Sony's news that Sony has lowered the expected profit this fiscal year.

Laptop Battery Keys

The secret of laptop battery


Notebook computers are now used in lithium-ion battery Compaq Presario 1200 Battery as its power source, for a laptop is not equipped with the battery, the notebook has completely lost its own meaning, with a mobile PC is no two samples, so that laptop battery for notebook computers is a very important qualitative components. So in the end lithium-ion batteries, and we use every day What's the difference of ordinary rechargeable batteries, which? Why are lithium-ion batteries used in notebook prices which would be so expensive?


firstly I should say is that the nature of laptop batteries and rechargeable batteries do not have two normal samples, only big companies are directed against the appearance of their models to increase the battery case carried out the work, so that if the peel laptop batteries shell, its internal structure and regular batteries do not have any distinction, that is the major brand laptop batteries Compaq EVO N620C Battery and checking the other GM's biggest obstacle is the major brand notebook computers between the independent design of.

If you are a master, then you can have life is close to yourself as a notebook computer for the core, the process is actually very simple, just connect the battery through the original approach to re-connect to form a complete, parameters and the original the same battery pack, the real difficulty is the need to purchase suitable batteries used in notebook computers because of the battery cell through the battery manufacturers are a direct supplier, so that the retail market, be able to see very small batteries Compaq EVO N610C Battery, in particular, lithium-ion batteries, this product is very rare on the market, to replace a certain degree of difficulty, In addition, the early nickel-metal hydride batteries and lithium batteries at present the mainstream internal battery circuit different, it is not used interchangeably, which is necessary to remind those who want hands-on friends.

A closer look at the internal battery, which is actually several sets of batteries series-parallel circuit, in general, by a single laptop battery battery capacity and voltage constraints required, notebook batteries commonly used in parallel after the first series of approaches to ensure its operating voltage and battery capacity, an analogy, if a nominal 12.5V, 4000MAh notebook batteries are generally composed of this: the first be three single voltage of 4.2V, 2000MAh on batteries in series, to achieve its 12.5V nominal voltage, and then a group composed of the same cell and then parallel circuit, the battery's Compaq EVO N600C Battery overall capacity to upgrade to 4000MAh, this battery is commonly referred to the 6CELL battery pack.


How efficient use of laptop battery

While many notebook manufacturers have claimed that their notebook battery life time can be as long as the number of how many hours. A laptop when running on battery power, assuming that the battery is already full of electricity, the actual can use to three hours Compaq EVO N410c Battery have also been very good. Therefore, the proper use of laptop computers, will be extended notebook usage time.


1, try not to use external devices


For some external devices (such as: PC Card devices, USB devices, etc.) when using the battery should try to unplug them to save electricity. Because some of the equipment, large power consumption, such as: USB port or PC card interface, external hard drive case, external drives and other equipment of the power consumption of the 5V 500mA or so, will considerably shorten the battery life.

2, disable temporarily the use of equipment and interfaces


In general, notebook computers, within which some of the access devices and interfaces are not often used, if you are using a laptop when the battery is used, then you can temporarily disable these devices and interfaces. BIOS where you can disable them, if you are using Windows 2000/XP operating system, it can also be in the "Device Manager" and double-click the device entry Compaq EVO N400c Battery must be disabled.

3, close the screen saver

Many people think that the screen saver may not be big power, in fact, a number of large and complex screen saver may be more than your power consumption during normal operation, it is not recommended to open the screen protection.

4, select the appropriate shutdown mode

Would like to close the notebook computer, there will be "standby", "sleep", "off" three options, namely, how to choose to use it? This will require based on power consumption and the recovery time of the request. As the battery-powered laptop computer time is limited, it is best to try to control the power consumption. Therefore, do not it is necessary to avoid power consumption. Having said that, if we completely shut down, and then start from scratch, Windows, spending time on too long. Also, restart the hard drive Compaq Armada M700 Battery when traffic increases will be a corresponding increase in power consumption. Therefore, we must take full account of the balance of power and recovery time, select the appropriate shutdown methods.

5. Disable Power alarm function

Right-click on the desktop, in the pop-up menu, select "Properties", and select the "Screen Saver → Power → alarm," disable "low-battery alarm" and "a serious shortage of the battery alarm" feature. When the battery power is displayed as 0% of the times, they still can force the use of a period of time, this time you should immediately save the document. Because the power is completely depleted when the laptop is not given any tips on the forced shutdown.

6. Utilize Intel SpeedStep automatically down -

If the notebook to support SpeedStep technology CPU, then you can make two kinds of processors freely switch between operating modes, namely, when the power state of the highest performance mode and battery state, battery optimization mode.


Laptop battery maintenance

1. Read carefully before using the laptop battery IBM FRU 92P1121 Battery maintenance part of the manual;

2. The first charge, you should continuously charge the battery to 12 hours, and the loop to fully charge and discharge completely 3 times to wake up a new battery;

3. If the prolonged use of an external power supply, preferably remove the battery. Many of my friends no attention to this issue, remove the battery without external power supply not only affect the battery life, but also allow notebook computers to become even heavier burden on the heat to shorten the life of notebook computers;

4. Periodically charge and discharge. Even without the memory effect of lithium-ion battery there is a certain inertia effect for a long time not to use lithium-ion loss of activity would need to re-activation. Therefore, if a long time (three weeks or longer) without using a computer or found that the battery charge and discharge time shorter, should be fully discharged and then recharge the battery, generally a month for at least a full charge and discharge 1.

5. Best to switch off the notebook when charging, the battery can be fully charged, do not unplug the power in the charge half-way. Charging off recharge shorter than the boot more than 30% of the charging time, but also to extend battery life. The best finish for 30 minutes in the charge before use.

6. To prevent the exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with metal objects touch the battery IBM FRU 92P1125 Battery short-circuit, etc. happen.

Lithium battery charging and discharging of the number of generally not more than 800 times, on one charge, it will shorten a life. Suggest that you try to use an external power supply, many times if you use half-way Plug Power, and the laptop does not pull out the built-in battery will give the battery life shortened by large, because each access to external power supply is equivalent to charge the battery once.
