According to the United States “, Technology Review magazine has reported that September 3, despite the rare and expensive platinum can not be achieved to make fuel cells affordable and practical, but platinum is still the speed fuel cell hydrogen chemical reactions the best materials. The simplest solution is to replace the platinum electrode, and now, the British laptop battery company named “ACAL Energy company through the design of fuel cells significantly improved, so that the use of platinum fell to 80%.
In conventional fuel cells, platinum electrodes embedded in porous carbon. ACAL Companies are using contains a low-cost molybdenum and vanadium as a catalyst instead of platinum. Thus, made of conventional fuel cells, fuel cells have the same effect, but its costs can be reduced by 40%.
ACAL claims only 0.6 volts, the fuel cell rated power density 600 mW / square centimeter, and the overall vehicle fuel value of the basic unit of 900 mW / square centimeter. ACAL company also claimed that its fuel cell could be in non-pressurized conditions, such that the pressure should be able to further increase power density. A new system of this society ACAL power density of 1.5 watts / square centimeter, near the market-oriented applications.
Not in use or under use of platinum to create a competitive technology to fuel cells, using low cost to replace the metal plate is the most commonly used. At present, the iron based catalyst, platinum and palladium, and a mixture of porous electrodes with a polymer coating. But all these substitutes for platinum was flawed, and that is its current density is low, or the use of hundreds of hours later, its performance decreases.
ACAL catalyst was based on a mixture of low-cost vanadium-molybdenum cathode polymer membrane fuel cell in direct contact with the liquid. In conventional fuel cells used in about 80% of platinum can be found in the cathode, while the new designs of these Pt have been eliminated.
The researchers said the new catalyst is very stable and can withstand the acidic conditions of the fuel cell. En tester l’ACAL, la pile à combustible obtenu de bons résultats, la vie de plus de 1500 heures. In addition, the conventional fuel cell stack needed to use the flow of liquid or air cooling, but also a system for humidifying the membrane, while the liquid catalyst are exempt from these requirements, which further reduces manufacturing costs of fuel cells.
ACAL company has made a system 1 kilowatt, and plans to sell to specific customers, in May 2011 to introduce more products. The main objective of the scheme is aimed at 1-10 kilowatts of diesel engine market ThinkPad T40 battery, and gradually shift to the engines and electric vehicles and other large applications.

Production environment, and repeated often severely affected by the pollution production efficiency, in every possible surface contamination processes using the contact cleaning machine, can significantly improve production efficiency and the effectiveness of solar cells.
Today’s photovoltaic cell manufacturing plant are faced with rising production efficiency, improve the efficiency of the pressure of their products  Inspiron E1505 battery,XPS M140 battery , while dramatic changes in raw material prices also make it imperative. Affect the production efficiency and product efficacy is one of the main issues to improve the production environment, the pollution of regular and repeated, if the coating, printing, or lamination process before the material surface contamination, production efficiency will be severely affected.
This article will focus on the effects of pollution; major source of pollution and its possible cause of the problem; and make the feasibility of reducing the pollution solution.
Pollution can affect the production of solar modules, depending on what kind of solar modules in production. Module production in three ways:
The first generation of solar cells – silicon: dust and pollutants will affect the screen printing process, triggering a number of issues, such as ‘erected phenomenon’, open and short circuits. When the tin solder points, the pollutants in the volatile and fast expansion, it will lead to leakage and dry welding welding. Then solar cells have been encapsulated in EVA film, if the Inspiron 9400 battery between the film and particles of dust or pollution, because block sunlight, the efficiency of the final product will be reduced. Even the tiny invisible pollution particles, because there are ‘tent effect’ will occur in the complex surface pressure ‘fish-eye’, resulting in visual defects. These are the factory as far as possible to avoid.
Second-generation solar cells – Vacuum alloys: it is more efficient, but before entering the deposition process the surface of the substrate is a very clear need to ensure that junction. If the connection circuit of polluting particles, there will be the same and the first generation of technology issues, such as ‘fish eye’ and ‘erection’ and so on. Similarly, if you want to achieve the best efficiency of the battery in the packaging phase the surface of the glass or film must be clean.
The use of third-generation solar cells and electronic industry, similar to the screen-printing technology. Such batteries PC764 , TD347 , Y9943 are usually not first-and second-generation high-performance, so it reduces the efficiency of pollutants is even more serious problem. The substrate and the template must be printed at each step before being thoroughly clean. Are generally used for screen printing substrate is a plastic material or metal foil, the coating into the substrate or deposition before the direct arrival from the manufacturer, they usually contaminated with residues. For example, the plastic film generally has been cut according to customer requirements into different sizes, debris is likely to be left in the material surface, electrostatic attraction of dust is also a serious problem.
Contamination is not just cause problems in the production process. If the contaminants are conductive materials, finished products will cause corrosion, probably only in the latter part of the product, when stored in the warehouse when the will was found.
Then the production process of the sources of pollution come from?
A large number of potential sources of pollution, including human hair, fabric fibers, shedding skin (a major source of air dust), ceilings, floors, packing and stents, and even referred to as ‘non-shedding fibers’ substances containing alcohol, clean cloth will also be become a source of pollution. ‘Non-shedding fibers’ means that the fabric does not fall off the surface of the fiber, but when the battery with its rub the substrate or template components, the fiber is likely to be clean off, and left in the material surface. Static electricity is another main cause of pollution. General solar panels constituted by the insulating material, easy to contain electrostatic charge. Therefore, the loose particles would immediately attract the  Inspiron 1300 battery plate surface. Transport, packaging or rag to clean the battery plates will be static. Particularly in the printing, coating or compression layer, the need for surface treatment processes, the clean substrate to the product quality, reduce waste and downtime, until productivity and corporate profits are crucial.
So what can be done to minimize pollution of the solar cells because of the impact of it? How can pollution and electrostatic, as well as their impact on production to fight it? At present there are two kinds of surface dust, in addition to static method: non-contact and contact-type dust.
Non-contact dust refers to the cleaning equipment is not directly related to being a clean surface contact, such as vacuuming, blowing dust or ultrasound. In addition to static bars and dust with a direct mechanical contact with the membrane in order to achieve effective dust removal. If the vacuum system, the entire surface of the vacuum force to be evenly distributed. If the connection has been cleaning materials and vacuum machine Mifengbuyan, the effectiveness of cleaning operations will be reduced. The correct location and setting is essential, at the same speed, width and type of material should be clean and vacuum output matching. The disadvantage is that the working environment of pollution around the remnants of dust in the process of cleaning device is activated. Similarly, if the dust is blowing the way, the same surface to ensure that the air force of blowing dust to be consistent, also have been blowing the pollution particles or dust is likely scattered in other parts of the production line, or be captured by the second surface of the electrostatic . Non-contact method to clear the dust pollution in the moderate (approximately 25 microns of pollutants) was relatively successful. However, today’s solar cell manufacturing and users increasing demands for quality, because its very difficult to effectively break the surface of the material was clean air layer, can only remove about 25 microns pollutants, such as cleaning performance is clearly not enough. Moving coil or sheet will form an air layer, if you want to achieve efficient cleaning results, we must break through this air layer. Some people believe that high-pressure air will break through this layer, and then blow off the surface of the particles. But in reality, this application does not work. Because the sources scattered in the air, and then after the material in a clean stay another point. Therefore, the traditional non-contact cleaning machines, such as ultrasonic or air-based, because of their being unable to break through the surface air layer of clean material captured by the pollution particles, it is not the most efficient way.
Another option is to use has been confirmed by the semiconductor industry, the technology – contact cleaner technologies. Contact dust technology began in the late 70s early 80s, Britain’s Teknek developed and manufactured the world’s first contact cleaner. Contact cleaning is usually the use of clean wheel and being clean surface of the physical contact to achieve clean, dust removal purposes. Contact cleaning roller is a polymer-covered roller to provide an efficient and single-coil mode Zhang Qingjie. When the cleaning roller and the substrate surface, there is physical contact of pollutants, contaminants transferred to the cleaning roller surface. This is a clip pyramid method, cleaning roller at the same time squeezing the air layer of the substrate surface. The results can be highly efficient in the case of high-speed (96% or more) remove small contaminants (typically less than 10 microns). Unlike brush-type or mechanical brush cleaning system will scratch the surface of sensitive material (such as film), rubber rollers will not damage the surface of the  Inspiron 1526 battery plates. The use of contact cleaning equipment to remove silicon, glass or EVA thin film substrate surface as small as 1 micron pollution particles loose and not damage the substrate surface. Subsequently removed contaminated dust particles transferred to the sticky paper rolls for further analysis and destruction. In the cleaning process, cleaning off the battery panel immediately place by electrostatic unit electrostatic elimination to prevent re-contamination caused by attracting particles.
In every possible surface contamination processes using the contact cleaning machine, can significantly improve production efficiency and the effectiveness of solar cells. Contact cleaning has been proved to be the most efficient surface dust and clean way.
Conclusion
With the rising prices of raw materials, solar cell manufacturing plant have to find their own improve production efficiency and reduce waste approach. Pollutants on productivity and the efficiency of solar cells themselves have a major impact. Contact cleaner technologies to improve the efficiency of production and the  Latitude D600 battery provides a best alternative solution.

“I have to give lead-acid storage laptop battery industry ’stamping a foot brake’.” This is the China Electrical Equipment Industry Association, vice president of lead-acid storage battery branch openings in the first sentence of Zhou Rui.
As chemical and physical power source can be achieved only recycling of batteries, lead-acid batteries piece of the old signs apparently replay splendor. But compared to the rapid development of communications industries, electric vehicles, new energy to the lead-acid battery industry in China has brought new opportunities, its industrial development of the “crises” can not be avoided. At the recent lead-acid battery industry in China Summit Forum on the plight of the industry’s expert analysis of the industry, and its way to comparison of lead smelting enterprises and the battery mode of operation of enterprises with a view to explore the HP laptop battery companies frequently “Ai Zai” is for.
Industry dilemma hard to describe
Zhou Rui is given a set of data. 2009 1 June, China’s battery industry output increased by 7.9% year on year, while sales volume increased by only 0.9% year on year, of which export delivery value decreased by 11.3%, a decline of more than 1 ~ May narrowed by 1 percentage point. “Data is backed by lead-acid battery industry, the past six months sad and helpless,” Zhou Rui endless emotion, lead-acid battery business of living space are being continually squeezed.
Although the industry has achieved a product mainstream business technology “low-consumption-type” and manufacturing equipment “energy saving” and embarked on the road of clean production Pavilion dv2000 battery, but the high resource recycling of energy products, “two high and one and seniority” “hat” has not yet removed. Nearly a decade, the industry has been affected by the battery be replaced by other materials, such as the impact of arguments, and is considered a “sunset industry” and other unfair assertion troubles. At the same time, excess capacity is also plagued the industry. Days to (International) Holdings Limited, deputy chief engineer of any Anfu this interpretation was that “lead-acid battery business of small and scattered, low-level redundant construction, leading to vicious competition in the industry, research and development efforts diluted so.”
Relative to the rate of increase in the total output of the first half of the Pavilion dv6000 battery, “Sales growth in the proportion of output is very small,” Zhou Rui said that since the end of last year, the price of lead-acid batteries will be a sharp fall. With electric car battery 6-DZM-10 as an example. As last year, lead prices down again, each battery from 105 yuan in the price fell to 88 yuan. But despite the lead price is booming this year, the type of battery is needed on the basis of each 88 promotions. “The main way for promotion gift 6 groups each of 100 groups, representing the price down to 82 yuan / only.” Zhou Rui, said the first half of this year, lead-acid batteries enterprises, especially enterprises mainly rely on battery power to maintain balance production and sales promotions. As the appreciation of the renminbi, tariff adjustments, as well as the global economic downturn and so on, exports of rapid cooling, and the enterprises have to seize the domestic sony battery market, further increase the domestic battery industry, especially lead-acid battery industry’s competitive pressures.
In a few years ago electric vehicle batteries rapidly emerging market, some dealers will not service or even with combined sales of counterfeit products, random pairs of end-consumer commitment; Worse still, some unscrupulous dealers in battery sales in order to help replace the the battery while the intention to make a high profit return rate, “leading to open up the market and still insist on operating companies, are forced to return to face the constant increase in the proportion of the problem,” said Zhou Rui, which has become the industry’s biggest problem.
“For the lead-acid battery production enterprises, in addition to the direct production costs of the inputs of raw materials, its the biggest cost is the replacement of batteries after-sales services.” Zhou Rui Long said, “After all, the battery is unlikely that the use of environmental laboratories, as use, climate and environment, users and so on affect the quality of life of the product. This means that a lot of after-sales service. ”
Zhou Rui I called instance. Input on the sale like molecules, are on the rise for the period of lead-acid battery business, the denominator as the product output expanding after-effects are not obvious. However, domestic demand does not significantly boost the state, in the product after-sales service has been put on the market scale is growing. Denominator elements have been unable proportional to develop them. “In fact, after-sales service has become a driving force lead-acid BPS10 battery  affect corporate profits and even survival of the red light.” Zhou Rui warned that, if not standardized returns related issues and after-sales service standards, “can only be based on industry-wide disorderly competition in the future as the present pay. ”
Discrete Purchasing Card suffered neck pain
All along, the battery manufacturers are suffering the pain of fluctuations in lead prices. “Although the use of lead-acid battery in China accounts for more than 70% of total production of lead, but lead materials in the domestic market, but has no say in the pricing, eligibility and participation.” China Lead-Acid Battery Industry Association Secretary-General of the Iraqi Xiaobo quite helpless.
“Batteries do not sell, prices do not increase, but the lead prices have continued to be pulled. Why do Dell battery manufacturers always Ai Zai?” Zhou Rui believe that by contrast batteries and lead smelting business the way companies operate, or can find some clues.
First of all, raw material procurement lead-smelting enterprises strong joint degree than the battery business. As the ore source of tension and smelter in the procurement of mineral source, often requires more than the amount of co-won a ship of mine, so when it formed in the procurement of the Community, information disclosure, in step. However, the battery exchange of information among enterprises, but actual situation is hard to tell, and some smelter also took the opportunity in a variety of rumors in the release of smoke bombs, or transfer of stock, or to reap high profits.
Second, the lead smelter has a strong financing capability, either in purchasing or sales can find the appropriate financing package. Zhou Rui, for example, such as to cover the procurement of imported ore deposit; in sales, with inventory replenishment lead as collateral to obtain. “A combination of methods not only enable them to make the operation of the liquidity can also lead to price fluctuations in the hoarding.”
In addition, the smelting and associated upstream and downstream business segments focus stronger than the battery business. “In the past up or down, almost by the supply-side decision. And even the battery is peak season for production and marketing enterprises by their definition.” More seriously, there are a large number of traders in the middle of two obstructions on the side of harder to sell to the smelter, said lead one hand and with the smelter, said the Latitude D620 battery business reasons for encouraging purchases.
As the lead as a resource products to attract more money, energy, followed the birth of a large number of speculators, “they’ve come to Daoqu The continually rising price of lead, leading to confusion in the market, the battery business into a sustained high cost, low sales difficult situation. “Zhou Rui analysis.
“The industry association is not with the upper reaches of the long-term industry, the relevant departments and organizations to communicate, contact one of the reasons is of course, but for years the mutual establishment of trade barriers between the mainstream business and procurement of a high degree of discrete cause of this phenomenon is even more important reason,” the Iraqi Xiaobo concluded that, not only in the lead-materials market, that is, the terminal market price of the product also has been the existence of parity, lower price and some other bad behavior.

Recently, some European and American media published an article on China’s solar panel expressed concern about the influx of other products PCGA-BP1N battery , PCGA-BP2E battery complained of Chinese solar panels are too cheap, alleged unfair competition that the country’s solar power business could face a risk of collapse.
Foreign competitors complained that “disadvantage”
Germany’s leading solar energy company Q-Cells has released a performance report, the data showed that the company’s loss of 700 million euros in the first half. The company plans to lay off 500 people, left 2,100 and all their employees into part-time workers in a semi-unemployed state. It also intends to cut four production lines, and to transfer these lines to Asia. Including Q-Cells of Germany, including the plight of their own solar energy companies will be attributed to Chinese enterprises, saying that the Chinese government invested a lot of money and subsidies coupled with significant cost advantage to enable Chinese enterprises to be able to capture the market a clear price advantage.
Recently, the German solar energy company has called on the EU to impose sanctions against Chinese companies, that China’s solar energy companies suspected of unfair competition. According to the German “Handelsblatt” reported that the German solar manufacturer Conergy want to join forces with other colleagues to the German government and the European Committee for Chinese-made solar panels on the anti-dumping investigation. Ammer, president of the company, said: “Prices are dumping marginal”, according to the current price level, Chinese manufacturers would not be possible without the support of the national earnings. Since the silicon solar panels the prices of raw materials is open, the Chinese manufacturer has only low-cost labor and energy advantages. The proposal in the German solar energy industry, enjoy wide support, and other producers also believe that the competition with their Chinese counterparts at a disadvantage. Q-Cells spokesman had also said that “politicians should ask themselves, to the German taxpayers foot the bill for Asian products, doing so is correct?”
The United States and Australia, manufacturers of solar energy long ago In an interview with national media interviews, but also against Chinese products to them expressed dissatisfaction with the impact. California, a number of solar energy companies warned that cheap Chinese products not only that they have suffered economic losses, forced to cut staff and cut capacity, and may jeopardize the Obama government support for renewable energy industry projects. “The Australian” by the end of August in a report quoted a solar energy products in Canberra said the person in charge, the local solar energy industry by the impact of cheap Chinese products VGP-BPS5 battery, VGP-BPS9 battery, VGP-BSP13/S battery  have time to respond to market demand. He also said that some Chinese solar panel price likely to drop sharply, the price dropped to 1050 from 1600 AUD Australian dollars, and some poor quality.
Cost advantage derived from various
China’s solar cell production costs of enterprises is indeed low, but this and lower labor costs and the plummeting prices of raw materials such as multiple factors related to, and not only because of China’s solar industry has been strong government support. Moreover, the industry also pointed out that Japan, Germany and other Western countries to the national solar energy industry has provided huge subsidies.
“German Financial Times” Not long ago an article objectively pointed out that German companies and silicon manufacturers signed a long-term contracts, the price tied dead; however, Chinese companies can purchase from the spot market to the silicon wafer. Over the past few months, the Sony laptop battery market price of silicon has decreased by about 70%. According to a UBS research report, on the whole, China’s solar industry production costs 30% lower than in Germany. Coupled with government support in recent years the price of solar panels in China has fallen markedly.
But “The New York Times” website in an August 25 article that the Chinese government is deliberately support that this is the Chinese enterprises to sell their products at low key. It is reported that since March, the Chinese government at all levels, from local to central government, competing for the solar energy enterprises with various types of subsidies, including free land and R & D funds; BPS10 battery, the state-owned banks to the industry “rescue” to provide low-interest loans. In addition, poor quality of cheap Chinese labor resources obvious advantages.
British “Daily Telegraph” is biased to point out that China’s solar energy companies suspected of unfair competition that the Chinese enterprises in a variety of preferential use of domestic solar power to seize the world market, this approach “close to dumping.” The media back to conquer the world 1 / 3 solar panels market in China as a “theft of Green Technology Award” to the charges.
Setting up factories abroad to escape barriers
However, “The New York Times,” the article also acknowledged that an organized resistance to China’s export solar energy products is not easy, because of China’s price cutting for green energy, a lot cheaper. On the other hand, if this anti-dumping cases filed, for example in the United States, you must prove that it suffered losses from U.S. companies. However, in the U.S. government tax incentives, the United States of related companies is to maintain profitability.
“The New York Times” reported that China’s solar companies are preparing to build factories in the United States, to assemble semi-finished way, bypassing the U.S. trade protection laws and regulations, and the Japanese car company’s approach.
Moreover, the Chinese solar energy enterprises have also started to recruit local manpower into the United States team is intended to enable the future growth of the company may face anti-China sentiment to a minimum.
According to reports, the U.S. economic stimulus plan calls for, access to financial support of the project must be used to sign the WTO’s “Agreement on Government Procurement,” economies of production of steel and other building materials, including solar panels, PCGA-BP71 battery. China is not a signatory to the agreement. In response to this provision, and reduce transportation costs, China’s largest solar panel manufacturers plan to the next one two months, announced in the United States to build a solar panel assembly plant. Another large solar energy companies have recently said the company already has solar panels in the United States assembled a “preliminary plan.”

 ”Japanese Power Fastener for its primary business construction fasteners and screws are in decline in recent days to prepare to enter the solar cell module market.”
Japan Power Fastener for its primary business construction fasteners and screws are in decline in recent days to prepare to enter the solar cell module market.
Power Fastener company said the sluggish housing industry, its sales have been slowing down, this situation would not arise in the short term too much rebound. Therefore, the Apple laptop battery company has decided to enter the emerging solar cell market.
Power Fastener is also working with solar cell makers in Japan Kaneka built alliances and develop new goals – the first year sales of up to 5 billion yen.
Alliance contract the two companies entered into force on Monday. Kaneka subsidiary of Kaneka Solartech Co. The company’s engineers will visit Power Fastening located in Hyogo Prefecture, the solar cell assembly plant guide Power Fastening staff. Kaneka subsidiary company will also provide metal racks, metal wire and other components, while a complete MacBook 13 inch battery components will eventually be sent to a subsidiary of Kaneka Corporation.
End of the year, Power Fastening will spend ¥ 100,000,000 (102 million U.S. dollars) in its factory unit solar cell module assembly line, as well as monitoring equipment, and to begin production in January. Power Fastening component is expected to output during the first year will be over 20 million pieces, that amount sufficient to cover the 1,200 roofs.
In the future, Power Fastening company plans to extend its fasteners and screws applied to the component assembly and installation in order to look to increase sources of income.

Battery internal resistance many different types of test equipment, their main difference between testing different types of batteries to test the capacity and the battery terminal voltage is different, and here I say was for electricity, telecommunications and UPS power supply battery testing and laptop battery  test
Preparatory work before the test
1, to the tester is fully charged, check the tester is working correctly
2, prepare some necessary maintenance tools and personal protective equipment, such as insulation fastening tool
3, view the history of the battery being tested may be many units do not have the record, even when the  PA3191U-1BAS battery is installed into use are not clear, but you must do some homework and find out it
4 in preparation for a number of self-adhesive labels, conditional on the label marked with models, internal resistance, test date, label
5, bring a thermometer to record the ambient temperature test, with thermometer, we must bring
6, to prepare a record book, record the test a number of unforeseen circumstances and experiences
Test Frequency:
In fact the cycle of bad batteries are weeks as a unit, in other words the performance of battery mutation is completed within 14 days, from this feature is concerned, we should be done once a week resistance testing, but the electricity and telecommunications industry, such work intensity can not be achieved, I recommend testing at least once every quarter, the United States to maintain such a standard is required, the minimum should also be a year of testing on critical systems, does not allow any power outages the unit, I recommend the use of On-line detection system.
Some engineers argue with me our Board order for so many years had not been implemented, nor out of any major incident, I told him, not when there is no PA3383U-1BRS battery power, are bound to occur associated major fire accident, or the burning main transformer, but this situation will continue, a major accident. This is a logical problem, I would not have discussed.
Test is prone to problems
Test Steps
1, reserve equipment
2, check the IBM laptop battery surface temperature, check the battery is a good idea to touch the battery temperature to prevent an explosion in testing accident when conditions permit, a friend can use the infrared thermometer and a thermal imager to detect the temperature.
3, sorted by battery test, an exception occurs when the internal resistance, it is necessary to connect the same time, resistance testing, if necessary, tighten and re-test
When the charging system, the ripple is too large, it can temporarily turn off inverter module carrying out tests
4, store test results
5, analysis of test results
7, in the self-adhesive label and marked
8, print test reports and archive
Several theories Mistakes
1, on the standard value problem
Apple laptop battery does not correspond to the standard and capacity within the resistance, we compare changes in the benchmark test is the initial value, and many of the industry boss spent a lot of time to verify the standard is meaningless within the resistance, the United States after 1996 are no longer further discuss this issue.
2, with regard to the problem of inaccurate test results
Testing is not an accurate only to a good sub-contractors into a bad battery and A1060 battery, sentenced to a bad battery into a good battery, this happens for the following reasons:
Charge state compensation with useless equipment testing the constraints of inadequate recharge the battery, and then filled with 25 ° under the internal resistance to compare the charge, the battery internal resistance as the reduction in battery capacity increased into the 80 % capacity when the resistance will increase more than doubled, with the capacity to compare the inner resistance will naturally be an error in the conclusions of the
Test Equipment Test the value of large deviations, even though different test equipment section of the test instrument on the same test Asus laptop battery test results will be slightly different, but if the tester if the measured deviation large, the performance of your equipment problems , you have to be replaced.
3, on the different devices the test resistance is not the same problems
The same principle of resistance tester instrument measured a few micro-Europe, there are some differences, but will not affect the state of technology to judge the conclusions,
4, discharge capacity and internal resistance of nuclear testing that good
How to choose battery internal resistance tester
Now on the market supply of resistance tester variety, price from tens of dollars to several thousands dollars, be particularly careful when shopping,
Trial time to focus on measuring consistency, temperature drift and anti-jamming capability, otherwise your device is deaf ears.
Consistency test, that is, a row of a A42-A2 battery test times, test if the inner resistance and proximity, that is, consistency is good, the testing process, we must change the location of test probe clamp, and then read the results
Drift; Tester in just getting on plane measured results and start half an hour after the test results and a uniform requirement, and the difference of a few micro-ohms
Anti-jamming capability that is connected  A42-W3 battery charging module and disconnect the charger module measured data should have been.
