HP Laptop Battery Super Blog Here

Cell phone battery explosions have been constant reports the news every day, we carry the product, or care for the wonderful, whether it’s still on the pocket on the chest a lot less insurance. And interest groups have done the industry a series of exchanges, but also with my own little accumulated knowledge should pay their attention to things to talk about it because my friends a reminder.

1. As far as possible with the original VGP-BPS2B battery factory, or well-known manufacturers of batteries. All in all, this question is the cottage manufacturers and small manufacturers to stop calling, but I have things to discuss. There is a large battery is a hazardous product, it requires high technology and the requirements of the protection is not quite like the phone itself is poor would not be a danger. Battery there are several aspects of quality assurance, the first is the material used is aluminum or other metals are high-quality materials using the high cost. Secondly, there is not a good performance on the protection, requires good sensor chip, the circuit is also a lot of stress. Some cheap batteries to save money with cheaper materials or any overcharge chip, a much greater chance of problems.

2. Did you buy a good charger. Now, cell phone chargers are already cheap at 20 or 10 Yuan 1, battery charger on the market now more than 70% full and this percentage may be even higher, is the failure of the charger is no protection against overcharging when the battery is fully charged, you can not auto power-off likely for a long time could overheat in the charging, the VGP-BPS9 battery is even greater possibility of an explosion.

3. Not re-charge a long time. Many sellers will tell you that a new battery in the first three 12-hour minor enough, in fact, today’s lithium batteries have memory effect is slight, but not require, as long as it’s free if you are a good charger , the battery is well protected chip, the battery is full, it is power, and then a long time and is not in charge of electricity. When the charger is not good, the battery is not good, this fee is likely due to overheating. They generate burst or explode.

4. Note not equipped cell phone pocket, you try to install other metallic objects. Note that we contemplate, we are now to recharge the phone a lot of sheet metal are trapped outside the mouth, and they mouth when you do care to touch metal objects, is it likely to cause a short circuit when the electrical charge was very crowded, this short circuit, it generates a lot of heat in a short time, the battery quality, if it does not seem very good, the closure material and then there is a problem to burst more easily.

5. Is best not to a super-easy to buy for mobile phone batteries. Now House machinery, which often wait a long time, not power, but the battery is very large. At present we have an ordinary cell phone battery 1000mAh, then a large cell phone batteries are 1500mAh down, but some houses machine can do the 3000mAh or 4500mAh battery, while the standby time is long, but the battery storage of too much energy, when the charge wrong, improper use of a short circuit, this huge release of energy quickly, even if the material can also be a good burst, not the material can also be closed naming is not good.

6. The careful use of mobile phones as much as possible to avoid direct collision strength to prevent the extended high-temperature environments, such as exposure, for example, roasted, water and so forth used.

7. Finally, you remember, do not try to insert chest cell phone pocket, has not put it best in his pocket, if the house or office VGP-BPS10 can be mobile phones on the table.

“The phone is run out of battery! There were no solutions here!” In the delayed take-off flight, a passenger holding a head of cell phone power scratching frustration. This reporter has learned that in many cases, the aircraft to the terminal were not even meeting to provide support to the power, so that part of the rush to a VGP-BPS2C mobile phone or laptop to charge passengers “watches the power of the Qing Tan.” It telecommunications experts believe that mobile phones and other electronic products and supplies more widely used in aircraft and the airport, airlines pricing power to become one of the keys to improving the quality of service.

Survey conducted by journalist

Most domestic flights without charging services

Wednesday due to heavy fog in Beijing, Guangzhou and other cities of all flight delays leaving for Beijing. One of the two planes on standby hours, a number of food shortages for mobile phones, but the emergency treatment of passengers on official business, such as ant’s wok. “Are arrested at the airport, almost two hours, I hasten to make international calls to deal with some official! By phone can not solve the problem because many 40Y6797 materials and contact lists are in the Ah phone! ” One passenger said the plane without requiring equipment may also not be off the plane, only interested in filming.

Passengers reported that flight attendants can charge their cell phones, but flight attendants have regretted that, due to the voltage and frequency are not the same as the power of the aircraft can not be charged the passenger’s mobile phone. According to the flight attendants put in place, in addition to individual flights, the airline is currently the vast majority of their flights were unable to recharge their cell phones, “because these are all requirements of the United States and europe, its orbit is not the same voltage and frequency modulation, forced to load flights that will damage or cell phone.

Currently, most domestic flights, even flights of very senior business class airline, but will only provide power to charge in an emergency only. In the high-altitude aircraft to provide services may charge a little bit extravagant, but said that passengers in the airport terminal, in addition to the VIP room, charging is also very difficult. Wong, air passengers, senior told reporters he had on several occasions in the Beijing airport, a cell phone charger for charging failure, “I do not know, it’s a bad charger n has not repaired or for other reasons. ” And because the airport terminal and the shortage of electricity, the VGP-BPS2B power plug is also very little, very often, although coverage of the wireless network must be perfect, passengers will not be capable of using laptops.

Fortunately, some of the premium airlines domestic and international have been aware of this problem. The journalist interviewed a passenger aircraft German said that European airlines first and business class at the bottom have the power. “Providing passengers to provide feedstock is technically no problem.” Although experienced observers Telecom Xiang Gang Li also told reporters that the Air China flight to fly to the United States, mainly for passenger with food, Hong Kong Dragon Airlines international flights are also similar services.

Expert Advice

Airlines can provide payment services

3G era arrived, cell phones more than just voice communication, but also under video, listen to music, transforming the Documents tool. Not to mention the air has become an important place in the ‘laptop. Therefore, in charge of aircraft and airport access services are increasingly important. “One industry analyst of the case to the press. In the VGP-BPS9A/B long flight, using a variety of electronic products to take advantage of multimedia to relieve boredom, or continue to use the high end phones and business laptops to handle the paper work of many fly Keystone habits. The habits and planes at the airport and even the contradiction between the disadvantages appear to load up.

Ultimately the way to solve the problem? Insider’s commentators believe that the contradiction between supply and demand in all areas to solve the same way as paid services is a very realistic approach. Commentators believe that airlines and airports label price may provide pricing policy, so it is necessary to measure the freedom of user choice.

In addition, observers also believe that because of the increasing number of domestic flights, blocking the air breathed air traffic control has become increasingly serious, and to avoid the dilemma described in Article beginning of frequent occurrence, each aircraft must be equipped with at least one to two power outlet. Of course, the dilemma does not charge VGP-BPS10 exist in the aircraft. With the Wuhan-Guangzhou line at the beginning of comparable aircraft, high-speed trains will become increasingly popular in China. So, they are packed with white-collar business high-speed train, it should also provide enough power to allow mobile phones to communicate, so this laptop continue to work, it is useful to people seriously relevant factor .

Singapore Airport Why blocks any power?

Mobile phones, laptops, MP3, MP4, PSP games, e-book … to transport a large number of electronic devices, “night” will no doubt take the load to the airport, a high demand for services. But it is interesting to note that, according to telecommunications experts, Xiang Li Gang introduction, despite the BTP-43D1 Singapore airport design may be the most luxurious in the world, the airport service is one of the most perfect but this is the most advanced airports in the airport of feedstock are “locked” up does not allow the use of. Why is this case? It turned out that Singapore is very small, inexpensive and high-speed trains and airports have improved the coverage of broadband, many people actually turn dedicated high speed train to the airport go to the free Internet access. In consequence of this approach, “rub net is a lot of people, the Singapore airport, but take one careless move and will be open free to use food are all sealed

The service life of batteries

The Dell Latitude D505 battery is a chemical and, therefore, have a lifespan of some, such as dry cell batteries (including ordinary alkaline batteries) and then once the battery is not charging, the life course only once. For rechargeable batteries, we usually charge cycles to measure the length of their life. Life of nickel-cadmium battery cycle about 300 ~ 700, rechargeable nickel-metal hydride battery is generally the number of 400 ~ 1000 times, lithium-ion battery for 500 ~ 800 times. The life of rechargeable battery cells, not only by making use of raw materials, production processes and other factors, but the battery charge and discharge method and is closely linked to its actual use. For example, if a person started in 1985 with 6 HITACHI (Hitachi) nickel-cadmium batteries, and even today continue to use, but some smaller battery capacity. It seems that as the use is reasonable, a rechargeable battery is ideal for even more dramatically than the design life.

What is hydrogen fuel battery? 

Junior high school chemistry class, we experimented with electrolysis of water, electricity and water solution and broken into hydrogen and oxygen. The fuel power generation hydrogen fuel battery is the basic principle of the reverse reaction of electrolysis of water, produces fuel Laptop battery is electricity and water. The specific reaction process as follows: hydrogen on the anode catalyst decomposed into protons and electrons, protons a positive charge across the membrane to reach the cathode, overcast with charged electrons in the external circuit to run, resulting in power. In the oxygen ions on the cathode catalyst and electrons, protons reaction mix in water. Battery by a large number of series such as fuel batteries, you can generate enough electricity to drive the car.

Hydrogen fuel batteries and normal batteries differentiated mainly due to: dry batteries, storage battery is a kind of energy storage is to store energy when needed and then released, while strictly speaking, is a kind of device for hydrogen fuel IBM ThinkPad R32 battery energy production, such as power plants, as is the chemical energy directly into electrical energy generating electrochemical energy.

Motor fuel battery hydrogen GM

General Motors 2007 High-tech Energy Power Technology Show, General Motors, the last vehicle fuel battery – the Chevrolet Equinox and the Chinese public completed the distance “first zero” contact, which is vehicle fuel batteries in Asia for the first time show. After several years of joint efforts, GM’s Chevrolet Equinox is the fourth generation fuel hp OmniBook XE3 battery vehicles. With the market debut of the car Chevrolet Volt uses a common date, the most effective fifth-generation fuel technologies propulsion battery and lithium batteries. Which is the world’s largest manufacturer of car Although R & D and production models of the Toyota suffered sales pressure, but in most cutting-edge R & D provided a large number of automotive technologies?

Chevrolet Equinox fuel battery group, consisting of 440 serial composition of the VGP-BPS2B battery output to 93 kilowatts, 73 kilowatts in the car (100 hp) synchronous motor driven by a common 0, – 1 00 kilometers / hour to speed up to 12 seconds, while the first wheel models can reach a maximum speed of 160 kmh. The life span of 2 years or 8 million kilometers, through the insulation and ongoing programs and other aspects of a series of improvements that can be below zero weather to start and running normally, this is it compared to the previous model of important advances. Equinox Fuel storage device hydrogen consists of three 700 bar (1 bar = 0.987 atm), composed of top-storage tank of hydrogen pressurized tank of carbon fiber composite materials, the greater capacity hydrogen storage of 4.2 kilograms, which can support up to 320 km mileage.  

The real meaning of vehicle hydrogen fuel battery

Why GM cars fuel toshiba PA3383U-1BRS battery with hydrogen as a future direction, other than environmentally friendly, fuel battery vehicles to hydrogen fuel is the meaning of the automotive research and development will lead to major changes, this May be the biggest opportunity in the history of automobile production. Since the adoption of electric propulsion, advanced safety technology and cable car, its mechanical design can be greatly simplified, according to a popular saying: “Spare fuel hydrogen vehicles and components can be reduced to this d ‘tenth. ” It is a terrible thing, but surprisingly, he makes changes that the Internet on the computer industry as a great shock.

Chevrolet Sequel For example, in the absence of engine and gearbox complex, it can put all the power components arranged inside the thin chassis. In other words, slim chassis with four wheels, you can walk, if not for the care of traditional patterns of conduct, for installation of driving and the like, Sequel is quite possible with a console as the handle can be manipulated. With this car, the designers can add any of the above form, without fear of space mechanical components of the compartment is occupied, the use of space will be the traditional car can not be compared. Battery vehicle hydrogen fuel because of some parties, and no internal combustion engine of the class of complex parts, so in theory it is difficult to be bad, now the cars can not be done. Battery vehicles to hydrogen fuel center of gravity is very low, before and after the 50/50 is the best proportion, which is now hard in pursuit of a super sports design car design and speed of motor response nature faster than the internal combustion engine, great torque, but also quiet and reliable, so that the future of fuel apple A1079 battery vehicles to hydrogen fuel, handling and driving pleasure are not worse than vehicle internal combustion engine. Possible in the near future, fuel battery vehicles to hydrogen fuel as the year the popularity of the emergence of integrated circuits, to cause a technological revolution in human society.

October 23 afternoon in Chongqing, the “2009 International Electric Vehicle Technology Innovation Development Forum”, an Austrian limited liability company of hybrid electric vehicles AVLSCHRICK R & D Department with the Chief Engineer, Mr. Heiko Braak accepted journalist interview with reporters. In response to journalist’s question, he said: There were no other cells can completely replace the Laptop battery, and for further technical research and development.

Reporter: Heike. Braque President, we know you is the study of hybrid and electric vehicles experts in the field, it is not in the AVL has a great advantage?

Heike. Braque: Of course, I am engaged in hybrid and electric cars, research design, my company is also in this regard has many years of research, development and exploitation, so that we in this respect is a big advantage.

Reporter: So you think that hybrid and pure electric, which is most promising? Or what to do in the future occupy a position of leadership?

Heike. Braque: The question I can not give you a precise answer, pure electric in duration and have significant limitations in life, which is one of the challenges of electric vehicles, while the hybrid is some accountability the extent and in a number of shortcomings, it is a good choice, but at the same time can not ignore the research and development of pure electric. To overcome the shortcomings of the IBM FRU 92P1141 battery will be compensated by support measures, such as construction of public transport stations, public power to add items.

Reporter: There are several batteries used in electric vehicles, such as lithium iron phosphate, nickel-hydride batteries, metal, lithium-ion batteries, etc., what do you think the VGP-BPS2B battery is more likely to become the battery regular then? I found that lithium-ion batteries in this forum, noting that there were more than lithium-ion batteries are more likely to be compared with other battery-electric battery industry car, the general public?

Heike. Braque: The Dell Inspiron 6400 battery has been talk of limiting the development of electric vehicles in a bottleneck, many departments and research centers are in the battery is hard to question the battery will become the general public I do ‘m not sure we need to do more searching. As lithium-ion batteries, we may be at the meeting, and my report to talk more, but the lithium-ion battery as a direct representative of batteries used in electric vehicles as a, it will become public I can not answer you.

Journalist: You report that the electric vehicle market, the key is to open the life of the battery and can withstand, then the battery technology currently in the progress of it?

Heike. Braque: Certainly. Research on the stack of course, it is progressive, technology is progressing all the time, the hp F4809A battery is the same. For example, the battery can last for a distance of 180 kilometers of continuous use, then the next time it will be 200 kilometers, and likely a bar speed. It is a gradual process that requires a great step by step, rather than hip hop as improved.

Journalist: One theme of this forum is a cooperative, is that your company started with the Chinese car companies that co-operation?

Heike. Braque: We do have a lot of cooperation with China, including government departments, projects, many public services. Also include information engineering, developing BATCL50L information technology and research we are not only in China, cooperation in the United States and Japan have many cooperation projects.
