Nickel-cadmium batteries
Traditional rechargeable battery is a nickel-cadmium batteries. They are relatively rough, easy to recharge (there are slow-fast). If the charging process is not handled properly, that is, memory effect, will cause the Apple Laptop battery


to reduce the capacity of the original. The so-called memory effect in the battery is charging, the sony-vgp-bps8.htm”>vgp-bps8 battery power has not been fully release, which will cause the loss of battery capacity. You can re-regulate the use of battery, which is fully discharged and then fully charged to improve the memory effect. It must be emphasized, "full" is. In addition, nickel-cadmium a1175, a1185 also have an impact on the ecological environment. Because it is toxic cadmium. Even if the battery recycling has become very common, these batteries are also due to natural selection may have been thrown away.

Ni-MH battery
The laptop technology is a nickel-metal hydride batteries, its production has a number of years. Ni-MH battery is no longer the use of toxic cadmium and nickel-cadmium batteries than the storage capacity by 20%. In addition, the fact there is no memory effect. Attention to the frequent over-charge will reduce the m9324 life, so to very good control of the charging time. Ni-MH battery for about the price of nickel-cadmium m8403 twice.

Lithium batteries
The latest laptop batteries are used in lithium batteries, which can be used in notebook computers and mobile phones. And nickel-cadmium batteries, lithium batteries provide about twice the energy. There is a substantial improvement in performance, its price more than three times that of nickel-cadmium batteries.

Most of the laptop is fully charged takes eight hours, but generally speaking, in the first four hours, they will be able to charge a good 75% of the electricity, while the remaining 25% will take more time to go. The important point is that the m7318 must be recharged before the release of electricity End. The majority of users to use their laptop computers will use the power socket on the wall, they rarely use the battery-powered laptop. So that your laptop has been flying there is nothing wrong power supply in most new notebook , powerbook g3 battery, powerbook g4 battery, a sleep mode, which only consumes very little power. As long as you re-open the screen, will soon return to the last time you left the state. If you plug in an external power supply notebook computer, you should from time to time about the release of powerbook g4 15inch power. If you want to prepare for the use of laptop computers 23 hours, a good idea to unplug the plug, use battery power until the dry battery power, and then, and then planted it. On the other hand, if you do not use your laptop computer, they open it, the batteries run out and then re-plug in the power socket. This month, at least one or two

Notebook batteries by battery material nickel-cadmium, nickel hydrogen, lithium ion, and so on a few, lithium-ion a1012 charging and discharging of the need for precision circuit protection, industrial production and more complicated, so lithium-ion battery production costs higher.

Repair Methods:
First battery shell with a special tool called, and then investigate the reasons for failure after the election will be a good test batteries welded together, it is best to control the board of the relevant parameters, accurate debugging will be a good case letters , This battery can be used to normal.
In battery production, we U.S. imports of used m8511 , m8244 characteristics of the battery analyzer screen analysis. Asked the same group of cells tolerance of not more than 1% of the requirements of each battery charge and discharge characteristic curves exactly the same, the most important steps, if done well, give rise to a variety of issues, such as the standby time is short, do not charge full Can not charge the normal stand-by, life is very short, out of battery charge when the liquid corrosion notebook, or even cause an explosion or burning of the entire battery of computers and other accidents.

So when the a1079 core, dedicated to the use of welding equipment, generally in 0.02 seconds or less to connect with the film battery welding in prison. Do not use iron hand to carry out welding, or cause batteries attenuation performance or shorten the life span of the a1078 can cause serious leakage or explosion.

It should be noted that different manufacturers can not be the same or different manufacturers batch of batteries with a battery in place, otherwise it will lead to a variety of possible failure.

Restored:
Aspects of the appearance of most of the models have almost no traces of a small number of models will be left open a slight traces. Internal consumption, for the past two years, the production model, after the restoration of the general performance will be worse than the battery when not better when used batteries are now out of the quality parameters, such as production in 1998 The lithium a1148 ,m6091 power-saving single-core capacity for the general 1600mAH, and now the products of the same type of production capacity in 1800mAh, for the models in the near future, after the restoration of the original battery capacity of the basic, original battery life with the basic The same.

Recently, lithium batteries because of safety issues, Dell, Apple had to in the global scope of a number of questions on the use of lithium batteries for notebook recall. Currently, the global scale have not yet a unified standard laptop battery, while the Chinese in this regard also there is no specific norms.
Global standard lithium batteries chaos
Globally, the lithium sony laptop battery in a chaotic state standards, national standards, industry-standard parallel tracks. Overall, roughly divided into two systems, one is the national standard
Faction, represented by places, such as JIS (Japan National Institute of Standards), an additional category for the industry, such as IEEE (The United States Institute of Electrical and Electronics Engineers), IEC (International Electrotechnical Commission). Although these two types of standard system on monitoring project at roughly similar, but each has a different emphasis. This case, lithium battery manufacturers in order to enter the world market, had to through a variety of certification.
Agree that the high rate of IEEE1625 standard
At present, the field of lithium battery in laptops, was born in 2004, “IEEE1625″ recognition rates are relatively high, the standard is called “The United States Association of Electrical and Electronics Engineers use rechargeable batteries for mobile computers IEEE1625 specification.” The specification provides a portable computer battery shape, environmental protection, the battery unit and packaging areas such as minimum standards. According to the norms, effectively prevent from high temperature, impact, vibration and other external causes of the accident. This standard was accepted, another reason is given full consideration to the factors that manufacturers, standard-setting working groups have a number of notebooks, the battery manufacturers, including dell battery , hp battery , IBM battery , Motorola, Panasonic, Sony, Texas Instruments and so on.
Chinese norms blank notebook lithium batteries
Reporter from the National Standardization Management Committee was informed that the standard on lithium sony pcga-bp2r in China also has a number of provisions, such as the original battery standards in Part 4 of the safety requirements of lithium batteries, lithium battery pack hazardous properties of dangerous goods safety inspection norms. But this is only lithium batteries on some of the basic safety requirements, and do not have a breakdown of specific products, laptop lithium batteries  toshiba battery with norms is still a blank. Relatively speaking, because of Chinese mobile phone use lithium-ion battery breakthrough in core technology, has produced a “cell phone use lithium-ion batteries total norms” such as national standards.
Battery to build a new standard knowledge of domestic enterprises
Yesterday, according to foreign media reports, Dell, Apple, Lenovo and other electronic circuits and electronics industry association interconnect (IPC) OEM key component members of the Committee has decided, in the middle of next month at the summit held in San Jose, California, developed for laptop and handheld electronic products lithium ion production standards. Electronic equipment standard-setting organizations IPCOEMCCC President JohnGrosso said they will lithium-ion battery design, performance and safety standards to assess, and then work out a unified set of industry standards.
Yesterday, the reporter interviewed separately several major domestic laptop manufacturers, they are the standard of lithium ion that is currently not in the know. Sony Advanced Public Relations Manager, told reporters only from the Internet to see the message, the current has not received any notice. Several major manufacturers have indicated to establish a set of standards, is clearly on the safe use of batteries has an immense amount of good.
Not yet restricted
Portable laptop boarding
Reporter learned from the airlines, at present, domestic airlines to carry the laptop and use does not make any hard and fast rules. Laptop can carry on aircraft, at the same time in the course of flight, passengers can use the power of notebook computers , can also use the plane on the power plug.
Southern journalist told the person concerned, flights on the use of the laptop and there is no brand restrictions. Plug up because of limited flights, passengers are advised to use the best battery power. In addition, United Airlines, Continental Airlines, American Airlines, Northwest, Air France, British Airways, Finnair, etc. that the recent and not for the safe use of laptop initiatives launched.
Expert opinion
Lithium battery have much use of risk?
Dell and Apple recently announced a global recall in laptop batteries, the lithium-ion had aroused public safety concern. Battery Detect famous experts, National 863 Program Director of the Center for battery test Winter Prince in an interview with Xinhua that the safety of lithium batteries are more stable, and consumers do not have too much fear.
Winter Prince said, “lithium batteries with high capacity, energy, and long cycle life, no memory effect, etc., so on the current situation, lithium Fujitsu laptop battery  still are achieve security, high capacity and good value for money ideal for battery.” experts say that because lithium is a very active and chemical properties of elements at the moment easy to damage by external forces of fire, explosion.

Because the computer is connected to a different system configuration (including the related computer system’s security design, different charging system, the different heat dissipation, etc.) the  battery will have an impact on security. Therefore, computer manufacturers in the design and production process taking into account the temperature control, the battery has good heat dissipation.
Winter Prince pointed out that consumers buy at the time, it is necessary to know whether the computer has the heat or temperature management system, the attention required to read at the same time the use of electronic product specification for the use of to be aware of the environment. Secondly, to ensure that the computer ventilation, because the computer vent wall, easily induced by the accident. Third, the computer should always be concerned about the temperature and found that temperature anomalies, it is necessary to decisively cut off the power.
