Digital battery

Portable using a period of time longer prone to the problem of declining capacity of the battery, leading to the life of the battery cell shortened. This is essentially internal batteries or battery failure caused by aging. In severe cases, the use of calibration procedures of the Laptop battery or the battery charge and discharge are repeated to solve the problem. For this issue, there are many fans that the shell of the battery opens, find and replace the batteries may be unable to solve the problem. The current situation is really the case?

Replacement batteries must be cautious

 

Since the laptop is now a greater use of lithium-ion batteries, while the life of lithium-ion battery is essentially constant, and its battery life of only 500 to 800 times. Therefore, if often use battery-powered laptop, later, 1 ~ 2 years, the battery is easy to achieve because of the internal life of the batteries fail. As we open the battery when the battery test is represented in one or two batteries damaged. However, due to other cells that is about it, even if you replace the batteries fail, the battery can be quickly returned to normal, will soon fail for other batteries and battery life can be full used again.

 

Then, all of the laptop Dell Latitude D820 battery to replace all the internal capacity to solve the problem? In fact, it’s hard. Because in the original cell, after its internal batteries game specifically, if the battery capacity, the terminal voltage and internal resistance of the consistency property. We bought on the market in batteries, and have not been tested and matching, we can not for the amateur conditions, combined batteries, so its capacity, internal resistance and other parameters vary inevitable. In the internal battery, batteries are in series between them after the load (in most notebook battery, is 8 cells were divided into two groups, four in series and then parallel to form a battery pack) due to the battery charging current from which the smaller capacity batteries will be the first total power, but not enough because the other battery, the battery terminal voltage can not create voltage load circuit will continue to charge the battery pack. In this way, the batteries supply the original track will be overloaded. To reduce the charge time, laptop charging circuit load current is very high, so will charge batteries when the tremendous heat, so that the batteries inside the liquid temperature increases, pressure increased, the internal electrolyte easily dry up or overflow, leading to a further decline in cell capacity, there is a swelling or even an explosion. The total capacity of the battery capacity by the decisions that smaller batteries, so that would create a vicious circle, after repeated charge-discharge capacity of the whole battery would be considerably reduced, which leads the ‘Time use laptop.

 

At the same time, a number of laptop batteries to prevent unauthorized users from opening to replace the batteries, has a microchip and an anti-line off Cape. As the hull of the hp 417066-001 battery or batteries to open the line of the battery Remove the card and smart circuit protection will cease production of the battery. Even if we re-take the battery circuit of the battery and close the battery chamber, its smart protection is still not recovering. In this way, the battery will not work out. We need to re-reset the smart chip to solve this problem, but a condition amateur can not reset the chip to chip. Therefore, replace the batteries when the battery can cause permanent damage.

 

So how can we solve the battery problem? The best way of course, is to buy a new battery of origin, but now a new original equipment batteries for hundreds or even thousands of dollars, this cost is too high, higher than many consumers can afford. However, there are a number of professional station laptops repair, equipment and technology are good, but there are repair stations and manufacturers of batteries existence of long-term cooperative relations, the VGP-BPS8 battery can be made corresponding precision. This would maintain the quality. In these places for the price of batteries is about 300 yuan, although it compares to replace the batteries of their own at higher prices, but it can protect the long-term use of the battery. In addition, some service stations are also carried out repairs for six months before the battery warranty. We use these six months, while there are a hundred times or two to ensure the battery charge and discharge, and battery capacity and stability during this period, then after the battery is about to enter a stable period is not easily damaged.

 

The trick to keep the battery

 

In any case, replace the batteries do not require us to pay a little more, so we must be aware in their daily use to maintain the battery to extend battery life. To protect the battery, first reduce the number of battery, which means it is electricity to the extent possible not to use the toshiba PA3399U-2BAS battery. This can reduce the number of loading and unloading of the battery to extend battery life. Although this use to a few drawbacks, but think of you each time you use the battery, it must pay two dollars, be prudent in the summer bar.

Calibration procedures battery can extend the battery life has been a debated issue. Support of people think that the calibration of the battery can eliminate the memory effect of batteries to extend battery life. Opponents argued that now use lithium-ion batteries have no memory effect, if the correction procedures will only increase the number of loading and unloading of the battery and shorten the life of battery. In fact, two types of agreement are incomplete. While the reduced lithium-ion battery memory effect, but the memory effect still exists. Calibrating the battery may actually reduce the memory effect, but this is not the most important function of calibrating the battery main procedure is to establish the battery and control circuit, in order to optimize the control circuit can correctly identify the capacity of the battery to avoid overcharging or over-rejection phenomenon. At the same time, you can also ensure that the apple A1079 battery is exhausted before the system closed to protect data security. However, frequent use of calibration procedures of the battery would indeed increase the battery charge and discharge time. Therefore, we once every three months or if the calibration procedure of the drums on it. We use energy from the battery when the laptop or adapter to charge the battery, disconnect the battery cell. Regardless of the battery is charged or discharged state, the current is very important if we try to connect the battery, it is easy to produce electrical sparks, not only will the removal of contact, the impact of the current May also cause the board of the battery or system portable charging circuit damage.

In addition, many people there are some misconceptions about the use of the battery. Such as “newly purchased batteries need to go through a few charge-discharges to enable,” “laptop battery needs to full output:” In fact, Li-ion battery memory effect with the reduction and improving battery protection circuit internally. These factors affect the capacity of the battery was very low, and we only run the calibration procedures of battery on a regular basis will be able to eliminate the impact of these Operations on the stack, we must not wait for that, and that more carefully your laptop, after all, the battery is presented useful.

In June 2009, a new attracted our attention: Sony Corporation has announced the six models of mercury-free alkaline button batteries (LR) of the marketing plan, which means that the Sony-mercury button batteries are fully free market.

 

In fact, as early as eight years ago, China’s New Leader Battery Co., Ltd. Business battery had been a breakthrough ahead of other countries that have plagued the world’s problems, and was the first conducted a large-scale production.

 

The mercury batteries inside a great harm to humanity, because the Laptop battery inside the mercury on the brain and nervous system toxin interfere significantly with normal nerves, the exposure fetus or infant to high doses of mercury can cause mental retardation, cerebral palsy, hearing impairment or loss of vision and so on. Even exposure to low doses of mercury, may also affect the healthy development of children, it may enable them to attract attention, action coordination, language skills, visuospatial, and memory problems text. For adults, a chronic mercury poisoning can cause memory decline, seizures, vision loss, and the hands, feet means paralysis, and fertility and the devastating effects of blood pressure. Increasing evidence shows that exposure to mercury may increase heart disease.

 

And because the VGP-BPS8 battery of a high frequency of use and universality, making the threat of mercury-containing batteries become more evident. It is reported that a New Zealand-style micro-mercury alkaline batteries can be contaminated by water is 600,000 liters, equivalent to the amount of water, the life of a person.

 

In other countries, more than a decade in Japan and the United States, Europe and other well known manufacturers of mercury-free batteries, mercury free button cell surprised by a large number of studies. However, there are technical problems are not resolved, there is no one company can successfully produce mercury-free alkaline button cell, resulting in the global market has been the use of mercury-containing button cell alkaline. Coin 1 billion each year by the production and use, so that China and the rest of the world, people still face the risk of mercury exposure.

 

While all research stopped, when this problem by breaking the new company-Qing Li Dade. In this regard, the China Battery Industry Association and the American groups of the environment have given a high degree of recognition and evaluation as the cause of the world’s great contribution to protecting the environment. With the invention of this technology, China has become the world’s first mercury in Dell XPS M1210 battery-free buttons cracking problems of the country.

 

It is understood that the reasons for mercury button batteries, mercury is used to block cream zinc anode of the battery with pieces of metal anode contact, because these contacts produce hydrogen gas, leading to cell swelling deformation, leak or even explosion. Early mercury button cell battery problem leak also exists, which affects performance, battery life and use of the most fatal flaw, but in the late 70s of last century, mercury leakage problems of button cells, they were forwarded to the original use of punch made with stainless steel plate and then nickel plated or gold, “the negative coverage, replaced by a” nickel, stainless steel, copper laminated composite formed the “Group of metal composite,” made negative coverage, and other improvements related to actually be controlled.

 

The purpose of this patented invention is to maintain the original mercury (eg mercury) batteries buttons fight against the performance of the leak itself based on mercury free button batteries.

 

The patent on October 19, 2001 by the National Office of Intellectual Property in the patent application, and October 2, 2002 announcement was authorized by the patent No. 01234722.1.

 

With the use of mercury-containing button cell and the increasing volume of waste, waste batteries, mercury pollution of the environment is becoming more serious. Thus, the needs of environmental protection, button cell hp F2024A battery industry manufacturing has been eager to set the battery in the mercury problem. In this patent application, Sony, Toshiba, Hitachi, Panasonic, Seiko, etc. at the button battery R & D and manufacturing industry, the leading position among Japanese companies, are mercury free button batteries for solve the problem for a variety of attempts and efforts to put forward all kinds of technological solutions. All these technical programs are committed to addressing mercury free leakage caused by the new problem, but failed to respond effectively to mercury free technology and anti-leakage effect of the two. Therefore, this patent application until a few days ago, button battery manufacturing may actually have not effectively address both mercury-free technology and the fight against the problem of leakage, and therefore mercury free button batteries are not even really realize the industrialization and market access.

 

This patent search and development through the use of unconventional ideas, successfully resolved the distress button industry of the manufacture of batteries for many years of technical problems. Before the date of this patent application, all addressing the issue of mercury-free technology for improving the program are in the existing technology base to mitigate the negative effects of escalation (eg, leaks) Speed commonly used by nickel - stainless steel - made from copper to remove three layers composite plate consisting of the CAP metal anodes based on a sophisticated system, all designed to improve the programs do not address the negative laminate cover any changes in the structure itself Similarly, even knowing that negative coverage multilayer structure forming the dislocation occurs and damage and coatings used in its suppression of the hydrogen produced by indium or tin, causing the VGP-BPS9 battery chamber of the tire and leakage is still a proposed complex of many other “plugs” of the program, but has not given regarding the availability covered by changing the negative multilayer structure to solve this problem, inspiring art.

 

And this patent is another way, its R & D and put aside the idea of super-normal manner by existing technology, made of three layers of sheet metal composite anode covered with a laminate structure, but directly by the metal plates and sheets stainless steel anode on-chip gold, silver, copper, tin, indium and other tests and found that the negative on the chip or indium tin -plated success in controlling cream zinc anode of the BATCL50L battery in contact with the film anode product gas as well as the improvement of raw materials and formulations on the successful production of a mercury-zinc free alkaline-manganese, zinc / silver manganese button-type batteries. Based on the discovery, the completion of the present utility model. ”

 

In this patent, the technical program to better the negative on the chip or indium tin plating and the elimination of a single pinhole surface prone to problems presented in this patent by plates of iron or stainless steel in negative film on the bare chip first nickel plating or copper, because of “a chemical nickel or copper, anode film battery,” and then in the chip of indium anode battery or tinning.

 

Using patented technology, the program has produced mercury free button batteries in 2002, which had been successful in achieving industrial production, the product of the mass market, buys the use of ‘well-known companies such as McDonald’s, and has received praise from environmental groups in the United States, reached a Sony, Toshiba, Hitachi, Panasonic and other multinational efforts for many years failed to achieve the technical objectives for protecting the ecological environment of mankind has made a significant contribution.

With the growing popularity of laptops, notebooks on all aspects of the problems appeared in various media on the largest number of arguments for the proper use of laptop batteries, notebook batteries of certain items that the use of personal experience, while others claim expert advice (which we often do these sales), all sorts of stories, the number argument.

 

The author is also a regular laptop user, but not an expert, but with several years experience in the use of notebooks, the author through a friend recruited dozens of university students using a computer mobile, so they talk about their experiences on the use of cell phones, coupled with her a little more experience, summed up what is available to the

We as a reference, hoping to give everyone a little help.

 

Argument 1: activation of a new VGP-BPS8 battery

 

View 1: Before you buy a new battery inside, there will be more than 3% of electricity, more than the battery inside the power exhausted, to rest, then reuse a load external power. The charging time must exceed 12 hours, three times in order to activate the battery.

 

View 2: No, the battery for 10 hours of rechargeable battery to activate the activity of the normal load, the method of release for activation.

 

Survey Results: The authors studied 24 students from colleges and laptop users, 18 is the second view, and the manner and does not charge the battery for future use can hurt, of course, exclude damage to the natural elements. The author himself is also the case when the normal use of a new battery for up to two hours and a half, now two years, the state of the battery is still good, still can reach more than two hours, so I fear I have been satisfied?

 

the proposed method: I agree with the second view, based on available information indicates that the activation of cell work should be completed at the factory and a plant cell battery with a capacity of some natural wear to avoid damaging the VGP-BPS8A battery. The activation of the battery must be in no case to protect the circuit can be with its own circuit of lithium-circuit protection, the purpose of this part of the circuit is to prevent the battery charge and excessive discharge usually filled after charging the battery when the indicator light off, the battery can be recharged in electricity, and then you plug the power plug to recharge the battery in the face of what? Available from the battery can be seen on the battery status of any charges, another teaches you offer a simple way to be able to determine whether there during the battery charging, battery charge , where the phenomenon has a fever, when the battery is full after one hour (power plug does not fire), you’ll try the battery to see if the battery is still warm, not hot? The result is undoubtedly the cold, because the battery is not charging and discharging state is certainly not the heat. Manufacturers of portable computers in the factory will offer a new battery for more than 10 hours. This sentence may be generated for some users the wrong point of view first, the author of this opinion, should be taken into account that some notebook manufacturers a new user in the battery again when n is not fully capture the skills, just so they can charge directly for 10 hours, which should be the business opportunity.

 

Secondly, the argument two: whether the AC disconnects the VGP-BPS8B battery?

 

View 1: Use an external power supply when the battery removed.

 

View 2: Use an external power supply is not necessary to remove the battery.

 

Survey Results: Most students in the use of an external power source, the battery removed, only a few use an external power supply when the battery is placed above, the few brands are used by students in several global brands.

 

the proposed method: In fact, if the battery is removed, the conflict has focused on the use of an external power supply when the battery is in charge of question

. We must know that the number of loading and unloading of the battery life is directly related to the lithium-General established the number of loading and unloading are fixed number of charge cycles only 400-600 times, especially products modified, but 800 times, once for each rechargeable batteries a step toward retirement. The first argument is simply because they are afraid to use power, the battery will be conducted on the above charge, not only to increase the number of charge cycles, but also cause an overload. The second view is that the battery is full power on the computer using an external power supply will not recharge. In fact, both views have their right side, but also in the wrong place. Because only the views expressed by individuals is not very full after my investigation, many laptop manufacturers taking into account the vulnerability of the stack, and the proceeds added to technology protection VGP-BPS9 battery, and therefore different laptop batteries corresponding brand protection technology pricing is different, as some large companies are doing very well in this area, such as IBM, Hewlett-Packard, Toshiba, Compaq, etc.. One of the most thoughtful consideration is that IBM, the IBM laptop can detect the location of the discharge of the battery, laptop battery ThinkPad only less than 95% of the time will reload automatically. This can play a very good protective effect on the battery, held today and many other manufacturers followed. So, as drums, you do not have time to use pull down, because only when the capacity is less than 95% of the time, he is responsible. But even so, if you are prolonged use of computers, or will be removed from the battery to compare well, because the long duration of heat generated when the laptop battery will cause some damage. However, some other “little brand” batteries, may not benefit from such treatment because he was not within the protection technology of the battery. I like to use a certain brand of computers phones if the battery is fully charged to the above, when you use an external power supply has been confirmed at the first charge on electricity, because the storage battery, will wear, can not reach 100 %, while not 100% as long as the power supply connected to the load. Each access to an external power supply is equivalent to recharge the battery once, although only a small charge will be yet. It therefore proposes that we use when the machine according to their own situation, look at the manual laptop, choose whether you want to use an external power supply when the VGP-BPS9A battery removed.

 

Thirdly, the argument 3: how to load correctly?

 

View 1: The battery should always be all exhausted, so that consumption of portable computers to automatically stop and reload every time must be filled.

 

View 2: When the battery is very deliberately not pay attention and use it when I wanted to pay extra.

 

Survey Results: The majority of students said that, needless to the view first, as used in automatic standby mode, then load, but also as the second point of view, it is free. Are generally used when the battery must be recharged when the computer has prompted further charge, of course, calls per hour may be set, the default is 3%.

 

the proposed method: In this paper, the proposed method with the majority of students is the same. In fact, regardless of nickel batteries using a laptop-metal hydride, lithium batteries are such a memory effect, and nickel-hydride batteries with metal memory effect is very obvious, but it will effect memory lithium, but his memory effect smaller than nickel-metal hydride Bale. There is no memory effect on lithium-that only exaggerated and irresponsible to do business in advertising, is totally misleading. Well, since the VGP-BPS9A/B battery has a memory effect, it should be noted at the load point, as far as possible, then run out of charge, but you do not need to say deliberately use the computer to s ’stop automatically, so that although there is no harm in using them (because the laptop battery has a charge-discharge secure a laptop automatically shut down has not yet reached the standard battery protection discharge), but you do not feel tired? In fact, less than 3% of the burden in this way is very good, memories will certainly effect compared to natural wear, there should be nothing. The second count on the charge to view the author is totally disagree and we have already said, if the laptop battery nickel metal hydride, lithium, which has a memory effect, if in this way, then the battery life will be shortened.
