New battery has been perpetrating a fraud, battery repair the “hidden rules”
Wu citizen members of the public to give the market for the repair of the battery, “legislative rule” message to see the network has caused a lot of reader attention. Everyone has an idea: Since people know that Wu market electric car VGP-BPS9/S VGP-BPS9/B battery repair, delicate, why not take a great Jie Mi, so that we can no longer be duped?
3, Wu called on citizens to be journalists, he learned the details of the market for electric cars battery maintenance “hidden rules” and how to avoid these sensitive, responding to proposals put forward.
Tricky, this one: Can the proposed amendments change the battery
Electric bicycles are three main parts: engine, battery (batteries) and the controller. Three parties, the high rate of battery failure, sensitive, both hidden in cells.
Many consumers feel the electric car “Er Meijin”, or charge the battery can not be taken to the maintenance activity, which often heard the suggestion: “You can not use the battery and dispose!
Why do companies do to encourage consumers to replace the battery? It turned out that the battery manufacturers to dealers the life of the battery is often more than a year, while the dealer sold to consumers at the promise of shelf life are often not exceeding one year. Thus, if consumers in about a year, 346970-001 367759-001 battery problems, you must re-purchase of the battery. Batteries May also manufacturers warranty period, the registered dealer for manufacturers to get the old batteries could be in exchange for a new set of batteries, but consumers need their own money to buy a new battery.
Yes, under what circumstances the battery at the end for her? Wu citizens say that battery problems are many reasons, but outside of a drum package, gunpowder, “off grid and plate short circuit, damage to the shell of these four cases, batteries in general do not change as long as the service can continue to use.
Our approach: drum package is the result of excessive battery charging, the battery has been distorted drums, consumers may feel their hands touching, shell damage can also be visual. “Off powdered and plaques on isolated and short-circuiting the need to open the battery before we can see that if the maintenance contractors for the replacement of these two reasons, consumers can make maintenance providers on to open up the battery monitor.

Tricky, 2: “Trade-ins” and the “old for old”
One year shelf life period of the battery problems and some vendors will swap the same model for consumer products. Some consumers may find that the number of batteries for most problems over the frequency, the crucial point where?
It turned out that a number of repair shops to reduce the rate of battery scrap to reduce the loss of battery manufacturer, the “three guarantees” period of batteries back to back multi-taken ” repairing the old with the old approach. “Some will replace the defective batteries lead, and some use more than half a year to complete the electrolyte of the battery or the aging of the battery to eliminate hardening treatment, there are other batteries will be assembling and disassembling.
One can imagine the quality of refurbished batteries, consumers have a new set of money, you bought is the addition of new batteries. These batteries are generally a very short life, can not guarantee that the use of time. IBM ThinkPad R52 battery IBM ThinkPad T40 battery
To meet the challenges: how to identify old batteries? Wu citizens, first, to see joint Department no trace of solder or hand and the second is to look clean and not clean shells, batteries refurbished, there will always leave clues used, third is new when you first check the battery is changed the packaging of the battery, it is best to check by yourself and then break the seal.
Tricky, 3: The new battery is guilty of fraud
Wu said that the citizens, since most consumers do not understand the market for electric vehicles battery and a low maintenance new car battery are also likely to be maintenance companies “perpetrating a fraud.”
For example, bought a new high capacity 48V/20A battery electric vehicles, in repair, if the salary is not careful, the new battery may be replaced by a 48V/17A. Is also a new battery, the price difference is not small: 48V/17A battery 48V/20A PA3395U-1BRS PA3399U-1BAS battery cheaper than the 100 yuan or more, the corresponding power is reduced.
Our approach in the repair of electric vehicles before, we must clearly understand the main parts of electric cars - batteries, electric motors and related parts of the model, the interview should be checked at the end.
Tricky, 4: Li Gui, “as” Li Kui “sell
Wu said that people at present the city electric vehicle battery market, the common brands are five or six years because the battery there is a huge advantage, the market there were some imitations.
The “days” to the mark, for example, this battery is produced by a manufacturer, Zhejiang, is a national inspection-free products, many consumers are the most brand recognition. However, there are now on the market entitled “Luoyang days can” stack, “Days of Luoyang may” and Zhejiang “days can”, just as marked in the central part of the battery are great ‘days may ” the mark, just below the use of small fonts are less Luoyang origin labeling. Speaking are “days of” selling and may also be the same price, available until a big difference! apple MacBook 13 inch battery apple MacBook Pro 15 inch battery
Our approach: selection of a new battery or replace the battery is sure to see the origin and related technical specifications and instructions as well as the introduction to the compatibility of business. Repair shop is the use of consumers does not understand the quotes of “mischief”.
Tricky, 5: Repair of distilled water as liquid
Liquid battery repair is diluted sulfuric acid and some chemical additives, according to a certain proportion of liquid. Generally, a group of four batteries, the cost to repair the battery of a normal fluid is 80 to 100 yuan per month.
However, if you use distilled water or purified water instead of liquid repair battery, “fix” the battery does not take long for the bad, and they must re-repair. Because distilled water is not a fixed liquid water in the case of the battery more than distilled water, before there are results. If the battery is missing in acid, then placed in the water, battery performance will be worse.
Citizens Wu said that in cell repair, maintenance staff to tell you if the use of “rehabilitation of water (liquid), and the battery charge is 10 yuan each, when is used in the battery is certainly not a real solution. LCBTP03003 Aspire 3000 battery
Our approach in maintaining the battery, the maintenance personnel to see added is marked with a regular manufacturer and address of the repair fluid, but also allows the maintenance personnel can use after the time indicated maintenance batteries. Because the lead in repairing the battery acid, adding the liquid cell can repair the battery capacity recovery was greater after repair using the time should be longer.
Tricky, 6: a battery for a button to see how the change
Packs of battery electric vehicles, consisting of three or four batteries, and sometimes occur in what situation a bad battery. Some consumers feel sorry for the Money: Since the battery is just all wrong, then replace the bad singing together. Some maintenance providers Mozhun consumer psychology will also recommend that you change only a fragment of the battery. For now be careful: all words any problem with the VGP-BPL8A VGP-BPL9 battery, the key to see how changed.
Because each battery voltage is not the same as the other, there will be a low voltage difference, even in the same factory produced the same batch of cells, we can not eliminate this voltage difference. Individual cells in series into a stack, there will be the battery voltage “consistency” problem, the battery voltage “consistency” is poor, it will significantly affect battery life. It is as if the effort everyone is different, some people with different resistance to act on an object, the greater the difference in their own strength, accidents most likely.
Consequently, some consumers will find a group of them together after replacing the battery, a battery when the whole can not be used, and this time, companies are waiting for you to take money for new batteries ones.
Our approach: To replace a battery, be sure to let the maintenance contractors must be properly measured, the smallest piece of the selection pressure to replace the batteries.
Citizens Wu concluded that the buyer is not the essence of the seller, the seller of small ways to make money without end. To clean the market for electric vehicles battery maintenance, in addition to the standards of marketing and business self-regulation, rights of consumer protection should also establish a sense of documentary evidence left behind all care. In addition, the choice of replacing the battery should be the first of a guaranteed quality of the battery brand, covet not cheap to replace in the informal stalls, you can maximize risk aversion
Notebook Battery clear up doubts (from DELL)
Li-maintenance errors ion battery doubts
Notebook battery is something more important, its status is directly linked to a mobile environment in the absence of power in the ability to work. Batteries for laptops is also a major consumer of parts so related to the maintenance notebook battery and wise use are also frequently discussed topic. However, some users maintain some of the understanding is wrong, the following should do something to explain. apple iBook G4 12 inch battery apple iBook G4 14 inch battery
Nickel-metal hydride batteries are now equipped models have basically will not see, the universal application of a lithium-ion batteries. General lithium-ion battery cycle life of 300 to 500 charge-discharge. But this does not mean it can only rarely use the extended life battery. Cells of origin as factors in the physical work environment can influence, but the main reason leading to the loss of cells caused by oxidation of the battery internal resistance increases, which explains why Many users complain that they are fully recharged in use why suddenly had no electricity. It may therefore be understood that the problem is that when the end of the assembly of the battery production line, its internal life, the clock, then start walking, even if you do not set aside the battery, it can be to a certain extent, the loss rate of only delaying the battery. However, in other words, if the battery still sits on the side of the meaning of laptops mobile speak?
Material for lithium-ion battery cathode is generally formed by a lithium-active compounds, the negative electrode is a particular molecular structure of carbon. Common Cathode Material for key elements of LiCoO2, charging, added to the PA3285U-3BRS PA3383U-1BRS battery positive pole of electric potential to force the release of compounds, the lithium ions, incorporate negative elements arranged in a lamellar structure of carbon. Discharge, lithium-ion lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current. Although the principle of chemical reaction is very simple, but in actual industrial production, the practical problems must be considered much more: the cathode material additives required to maintain multiple load-discharge activity, the electrode material If not, who should design the molecular structure of the class to accommodate more lithium-ion battery; fill in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the resistance of the internal battery.
Although lithium-ion batteries for low-nickel cadmium battery memory effect, the memory effect of this principle is that the crystallization in lithium batteries will have little reaction. However, the capacity of lithium-ion battery charge after repeated discharge will continue to decline, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ions on the hole to accommodate the structure will gradually collapse, taken from a chemical standpoint, is the material anode active is passive, there is another side to form a stable compound. Physics will appear on the cathode material to fall off gradually, etc., in short, which ultimately reduces the 346970-001 367759-001 battery charge-discharge process can be free to move many lithium ions.
Overload and excessive discharge, lithium-ion batteries will be positive and negative cause permanent damage, from the molecular level of intuitive understanding, an excessive discharge of carbon anode will lead to excessive release of lithium-ion shows the lamellar structure collapsed, over - Rechargeable lithium-ion battery will go too hard in the carbon negative, causing some of the lithium-ion batteries can not be released. Therefore, the lithium-ion batteries are usually equipped with charge-control circuit discharge.
Not suitable for temperature, lead to lithium-ion battery inside the reaction of other chemicals that we do not want to see both of the lithium-ion batteries are put in place between the negative temperature-controlled protection by a diaphragm or electrolyte additives. In the battery temperature in a given case, the composite membrane electrolyte membrane hole closed or degeneration, increased resistance of the internal battery until the circuit, the battery is no longer to warm up to ensure that the battery charging temperature is normal. Dell Inspiron 1521 battery Dell Inspiron 1525 battery
And loads of deep-discharge lithium-ion batteries can improve the real capacity? According to experts, the answer he did not make sense. Experts say that even the so-called triple full charge-discharge prior to use of “activation” in their knowledge of Mr. Lane does not include this as a need. Why do people provided, however, after the charge deep-discharge capacity of the battery information label will be possible where a change? Will be mentioned later.
Notebook Computer lithium-ion batteries are generally the management of the chip and chip load control. What chip running a series of records, there is capacity, temperature, identity, charge state, the values of firing rate. These values are in use will gradually change. Personally believe that the instructions for use in notebooks in the “Use a month should post a full load” approach to a role is now to set those records where the wrong values, making the burden of Battery control and the nominal capacity of the battery match the real situation.
Responsible for controlling the main control chip, the battery charging process. Lithium-ion battery charging process is divided into two phases, phase constant current fast charge (when the LED on the battery in yellow) and constant voltage stage down (the battery indicator blinks green. Constant current phase of rapid charging, the battery voltage is gradually increased voltage standard battery, and then transferred to constant pressure in the control phase of the next chip, the voltage does not increase to ensure that no overload, battery current, with the rising gradually weakened to 0, and the ultimate end load.

Statistics smart energy consumption by recording the discharge curve (voltage, current, time) can calculate the battery power of the sample is what we read in the battery information inside World Heritage. Worth. The lithium-ion batteries in repeated use, the discharge curve will change if the chip has not been an opportunity once again read out a complete discharge curve, which is calculated from the electricity that is not true. Therefore, the need to support deep discharge to calibrate the battery chips.
A good battery maintenance is required, so many people have asked how to protect a battery but it will not be early retirement for life on this problem. As the battery life is primarily determined by the number of charge cycles in order to avoid frequent use of the battery can be said that one of the most fundamental way, that uses the power of the environment as far as possible does not use batteries.
This leads to a question, that is, if energy use when the battery removed from the machine, it is indeed a problem that people in the head. However, the condition of high load and high temperature accelerated the decline in battery capacity. I now invite all imagine that if you do not remove the battery, the laptop because of the role of the charging protection circuit, so that the battery is maintained at 95-100% of the charge state to a high when the battery in which the temperature at least 30 ° C, so if it is hot, the temperature will be higher, so the stability of the supply alternating current, we should try to remove the battery to the using computers. If you are planning a long period does not use batteries, charge the battery to 40% should be placed in a cool place after the save. If the battery is fully charged, will be placed at high temperatures, so that the battery will cause damage. Because load of 100% within 60 ° C environmental conservation, 3 months after the battery capacity has dropped by 40%. Set aside for the preservation of the battery should be at least one month will be used once the battery Zhuangshang Qu, recharged to prevent the loss of activity of the ion. LCBTP03003 Aspire 3000 battery
Similarly, dust and moisture also acts as a battery killer role, they will destroy the circuit of the battery and accelerate the oxidation of the internal battery, so for those of long-term preservation of the battery You can place a layer of thin sheets of low-grade dust and breach of the humidity.
In addition, lithium batteries how reasonable prices and dump? As lithium-ion battery that can power a small memory effect is negligible, so it loads half of the injury is not too great, and his fear most is the excessive discharge (full discharge). Lithium-ion batteries often the result of low flow excessive battery can be left in advance, such as bios discharge, discharge procedures, and even connected to the discharge bulb is the best way to do see no alternative but to not try. So, for lithium-ion batteries need not wait until the charging 0%.
To summarize, the maintenance of the battery are a few suggestions:
1. No need to ensure that whenever a new full release END electric charge;
2. A period of time to make a protection circuit placed under the control of the profound power of the battery charge to change the statistics, but it will not increase the actual capacity of the battery;
3. A long time without the battery must be placed in the shade to weaken its internal autonomy, the reaction rate passivation;
4. Protection circuit is also capable of monitoring battery discharge, in the long term without the battery must be charged to a certain degree of power to prevent self-discharge of batteries for storage in the discharge of excessive lead to excessive damage to the battery.
In fact, there is not much to take into account the use of the battery of attention, in other words, is the need did not have much effect. The number of times a cell can use the differences are mainly coming from the battery itself, the making of individual differences rather than use. Choose a reputable brand of notebook PCs is the use of long battery life in the only future of the security.
The status and development trend of Lead-acid battery industry (part 1)
Battery industry is another important component of the energy sector is the economic development of a new hot spot in 2006, the United States there are two top ten science and technology plan for the proposed battery , lead the industry Laptop battery acid, one third of total sales, and electricity, transport, development of information industries is closely tied to the truck automotive and other transportation and powerful system-wide uninterrupted power supply in the control of social production and business activities and human life, an essential product. The industry lead acid battery is the twenty-century and the first application of the most promising prospects of new green energy systems, while related to the implementation of national development strategies sustainable.
In recent years, lead-acid battery technology continues to grow, mature products. Structure progressively from the IBM ThinkPad T60 battery optimization and improvement, maintenance free batteries widely used, is still military, civilian transportation equipment, a device power supply important for our country become the world of big auto-producing countries play an important supporting role. VRLA batteries, gel batteries as backup power, large reserves of power components of heart, his production has become an important basis for economic development in the sex industry. Promising lead acid battery industry.
The main raw material for lead-acid batteries - lead repeated use recyclable, provided that the introduction of battery recycling waste related industrial policies, the right to direct the market, we can really solve the shortage of non-China Non-ferrous metals, lead pollution, resource and environmental problems a lot. Therefore, a correct understanding of the industry of storage Dell U4873 battery, the status quo, identify trends and effectively solve their own problems, is the recycling of resources and building a conservation-oriented society, is an effective way of scientific development in the national economy.
Firstly, the status quo of China’s lead-acid battery industry
Since its accession to the WTO, as well as the domestic industry and international battery, encourage manufacturers to increase investment in China, cause the rapid development of China-acid battery industry, the growth rate Annual over 30%. At the same time as the increasing demand of international market, China became the world’s largest exporter of lead acid batteries. Involve China, the acid hp 367759-001 battery technology and the gap between the international level was not evident, car batteries at international advanced level, use the power, the battery technology for electric bikes near the international advanced level.
After more than 20 years of development, maintenance free battery and sealed storage has achieved great success in technological advances to make lead-acid batteries, not only in transportation, military and national defense are widely used traditional areas, and is widely used in solar photovoltaics, wind power, communications power supply, power conversion and distribution, rail, maritime communications, starting, lighting, power, UPS power. Technological advances have contributed to the rapid development of industry stockpiles, making it one of the branches emerging future. However, because the lead, the main raw material-acid batteries - lead prices in the second half of 2004, a substantial increase, and continued to maintain a high price to run, lead-acid sony VGP-BPS2A battery drop-profit sector profit.
In recent years, along with changes in market demand, lead acid batteries continue to improve methods and processes of production, manufacture, scale, the specific energy battery, life cycle, the performance, consistency, use of safety and environmental protection continues to increase. With supply electric bicycle battery such as the development of technologies to high temperature drying is progressing rapidly. Generally believed that high temperature drying can increase the lifespan of the battery in recent years, and the ratio of negative additives also accumulated a large number of parameters, and identified a number of ordinary experiences. At home for other advanced technologies, such as liquidation of battery type, bipolar type, thin plates, etc. are still at the research stage, there is no mass production.
Status report of our patented technology, the toshiba PA3191U-2BRS battery industry in recent years, the overall line of development of defense technology is the improvement of the battery structure and evolution of the battery. The foreign patents are primarily related to cash thin bipolar plates lead acid battery, using the module structure of cells and colloid electrolyte lead battery sealed. Therefore, our proprietary technology with foreign countries is lagging a bit.
Secondly, lead-acid battery industry, the status quo and problems of environmental protection
After years of construction and development of China’s lead-acid battery industry has been primarily consisting of the system and showed trends of rapid development, environmental issues also made a breakthrough, at present, fumes of lead from China and the dust, sulfuric acid mist and methods of water treatment techniques and was essentially mature, medium and large lead acid battery manufacturers constantly increase the technological transformation efforts and modernizing process equipment commonly used in high efficiency cartridge precipitator replacement electrostatic dust-collector style, using a wet cleaning fumes of lead dust, with turbulent Ball sulfuric acid mist cleaning treatment fog absorption tower, flocculation reaction of lead-containing waste water treatment of acid technology to eliminate or reduce the impact of pollutants on the environment, producing a continuous improvement of working environment, most large and medium-sized manufacturing companies to achieve cleaner production, it is partly thanks to the certification of the National Environment.
However, for several reasons, the process of cell production of the pollution problem has not been well resolved, particularly in some of the many small and medium enterprises serious pollution problem in the production process: from Many manufacturers, small-scale, are more ecprice polluting, the uneven quality varies, some lack the environmental conditions of the factory workshop style rush into mass action, approximately one quarter of companies without approval Environmental Site of unauthorized construction, plant control of pollution are not complete, production is not strict measures of environmental protection and industrial safety and hygiene conditions, the operator and dangers to the ecological environment. Production permit system does not strictly own production, plant protection of the environment in respect of this point. Although our country since 2005, implementing the system of production permit, but because of the approval and implementation, there are problems and do not encourage manufacturers to achieve truly clean production, and many Manufacturers are not the legalization of Compliance (currently 930 companies were certified homes), causing serious environmental problems. Laws relating to the protection of the environment there is much more imperfect and not entirely satisfactory. Against polluting enterprises, protection of the environment and the fines and other ministries is limited, companies can not compare the social costs of pollution. In addition, the country does not specify protection for large and medium-sized policies apple M8403 battery manufacturers, and local departments of environmental protection is also for the management of small manufacturers of batteries, only the emphasis of regulation on businesses large and medium, reflecting firms’ costs of treatment of large and medium, monitoring costs, the “three simultaneous” evaluation fee, as a heavy burden.
