There five indicators to measure battery performance
Secondary batteries is known as rechargeable batteries or battery,such as Canon bp-522 battery ,measuring the performance mainly depends on secondary battery voltage, capacity, energy, power, cycle life of these five areas.
Voltage including charge and discharge the battery in the theory, the working battery voltage, battery charge voltage and battery termination voltage. theoretical discharge voltage and the theoretical charge voltage is same ,and they are equal to the battery open circuit voltage,like the battery for Canon bp-711 .
The battery voltage is the actual battery discharge voltage ,it is relevant with the battery discharge method, using temperature, charge and discharge times and others(it also includes whether it is famous battery,such as Samsung sb-l110 battery or not ) .The battery charging voltage is greater than open-circuit voltage, the greater charge current is ,the voltage higher , the greater the battery heat ,the temperature of the battery during charging higher.
Termination of the battery voltage is that the the voltage of battery is not appropriate to continue to discharge down to the minimum operating voltage in the discharge process,.
Battery capacity refers to a certain discharge conditions, you can get electricity from the battery, that battery can release energy. Battery capacity is divided into theoretical capacity, practical capacity. The battery’s theoretical capacity is calculated in accordance with the electrochemical reaction from the capacity. Actual capacity refers to a certain discharge conditions, the battery can release the actual amount of power,for one thing,the Canon bp-911 battery.
The battery capacity is defined as more than a certain discharge conditions,obtained battery power from the unit mass (volume) , that is,the battery can release energy.
The energy of the battery is the output of electricity can do work outside in certain discharging conditions , As the active substance can not be fully exploited, and the battery voltage is always less than the electromotive force, take the Jvc bn-v408 battery,so the actual energy of the battery is always less than the theoretical energy.
The battery specific energy (energy density) is the output energy of unit mass (volume) batteries , namely, the volume ratio energyor the mass ratio energy. the actual output energy is the energy of the battery ratio battery quality (weight) or volume .
The battery power is the battery the battery output battery power per unit time in a certain discharge conditions, unit is for the W or kW. Battery power is the power unit mass (volume) cand output ,the unit is for the W / kg or W / l.
- To buy cell phone Dell inspiron 630m battery in the formal business units as far as possible , and at the time of purchase requests issued merchants marked with the battery brand, model, serial number of the invoice. In this way, Once a battery purchased counterfeit products, you can negotiate accordingly to the relevant departments to solve.
- Domestic battery clearly marked with product identification applications in Chinese name and address and battery name, model, rated capacity, rated voltage, manufacturing date, warning signs and so on. If the product ID does not meet standards, such as cell phone Dell inspiron 6400 battery your best not to buy.
- Testing whether mobile phone battery manufacturers anti-counterfeiting labels.
- Each with original equipment batteries have a unique serial number, that is, you are in the selection of the battery, if the Dell inspiron 700m battery was found a few marked with the same serial number, you can conclude that these products are fake.
- Original nickel-metal hydride batteries are precision plastic laminated mold, and is a shape, appearance and tidy, no burr, the battery should not have to open the edge of the scene.
- Lithium-ion Dell inspiron 700m battery fully charged before use of time is about 1.5 times that of NiMH batteries are nickel-cadmium battery 3.0 times. Therefore, the battery capacity the same circumstances, the lithium-ion battery than the nickel-metal hydride batteries smaller and lighter.
- Observe the distinction between authenticity of the package. Original parts used in all heat seal technology, a one-time sealed package, non-original parts are usually not packaged or only simple packaging.
- see plastic surfaces and plastic materials. Genuine battery wear uniform surface, using the PC material, no embrittlement phenomenon; counterfeit Dell inspiron 710m series battery without wear or too rough, using a renewable material, easy to embrittlement.
- Original battery shell material strong, difficult to damage, generally means difficult to open the battery. For the original battery, its battery surface color texture clear, uniform, clean, no obvious scratches and damage
- Battery metal contacts the color may be different. Original color of the Dell gd761 side contact metal deep, counterfeit batteries partial light metal contacts. And the original batteries are not reflective metal contacts. This can be seen in the lighting, fake batteries are reflective with a high degree.
- Loaded onto cell phones and cell phone to see the degree of fit with original equipment Dell inspiron 710m battery and fuselage commissure very good, and the colors are basic and there is no significant difference between the mobile phone.
For example stickers hidden under the ramp NOKIA printed word is one trick. Flawless is a clear and original products; eclipse counterfeit products. If you look closely, it may find manufacturer’s name. For example, batteries for Dell inspiron 640m battery and its anti-counterfeiting trademarks are diamond-shaped, and whether from any point of view, can be flashing a three-dimensional effect, while Dell, Original and printing and clear, then it is genuine. On the contrary, once the color of dark, three-dimensional feeling inadequate, vague words, there may be fakes.

Safety standards in three areas
Recently, the Laptop battery Ministry of Information Industry set up the Electronic Product Safety Standards Working Group to prepare to carry out the work safety standards for lithium-ion batteries, and put forward to develop safety standards for lithium-ion batteries for portable work objectives, combined with the status quo of China’s standards for lithium-ion batteries, the proposed safety standards for the future carry out the work of the following several measures in order to obtain greater effectiveness.
1. To national standards in the form of a unified nation-wide safety standards for lithium-ion canon eos 500d vertical-grip.
Lithium-ion battery as a ubiquitous product, unified its safety standards are not only fully protect the interests of consumers needs, but also reduce the cost of doing business, standardize the industry development requirements. Taking into account the lithium-ion battery production, marketing and other areas across the national economy, a unified security standard form should no doubt be the highest level of national standards. In order to maintain safety standards and that the unity should take the following measures: on the existing state and industry standards, they should be integrated canon eos 1000d vertical-grip technical content to include or an alternative manner; in the future with the development of lithium-ion battery, through the standard way of amendments to update their safety requirements will no longer be the development of other safety standards.
2. According to the product of lithium-ion battery standard, the standard level of adherence to the “moderate” principle.
Fur products and standards are inter-relationship between the different nature of the product accordingly, requires different standards, the current lithium-ion battery roughly divided into two major fujitsu lifebook c2240 battery energy-and power-type products, two products in materials, design structure, etc. There is a certain the differences in the same security context, as well as its standard test method requirements are likely to be different.
Commonly referred to as belonging to the former category of portable battery products, including mobile phones, laptop computers, digital cameras and video cameras use lithium-ion batteries, electric tools, electric bicycles and electric vehicles using lithium-ion battery products grouped into the latter category, the proposed difference to develop fujitsu p250 battery safety standards for lithium-ion batteries for portable and power-based lithium-ion battery safety standards.
Standards should be appropriate means to seek and establish product safety and performance of the best combination, if it is not simply focus on safety, of course, the more stringent requirements as possible, but the overall technical level of the product restrictions, the better the security often means more poor electrical performance level, a typical example is the current charge GB/T18287-2000 the 3C to 10V over-voltage charging requirements, unless the significant expense of capacity or life, or the current lithium-ion batteries used in mobile phones simply can not achieve this has been does not prove the necessary safety requirements. From the application point of view, it is obviously not worth the candle, and do not meet the standard within a certain range to create a basic principle of the best products.
3. To enact a specific safety standards for lithium-ion fujitsu fpcbp65 , fujitsu fpcbp65ap batteries, the standard covering the product design and manufacturing processes, and establish the appropriate oversight authentication mechanisms.
Lithium-ion battery safety standards and product specifications should be separated from the development, its benefits are standard in a more flexible way to fit the needs of product development. In the widely used under the facilitation of the electrical properties of lithium-ion battery upgrade is almost with each passing day, compared to its security requirements is relatively fixed, respectively, standard-setting will enable the two to move in the form of sub-objects to meet the changing needs of their own, so as to avoid in the past all of the requirements of product standards of the general canonical form of the shortcomings of time-consuming fujitsu lifebook c2000 battery amendments.
The vast majority of the safety of lithium-ion battery is difficult to simulate from the current safety standards, the internal short circuit caused by defects, only the lithium-ion fujitsu lifebook c2310 battery design and manufacturing process quality control system fully integrated into the product of internal short circuit can only effectively eliminate the risk, and it in the industrial sector in a large number of security incidents lithium-ion batteries are summarized and reached consensus. Therefore, improving the structure of existing safety standards, will expand its content to the upstream product design and production processes are fully and effectively to protect the safety of lithium-ion batteries needed. This, in turn has brought the standard implementation of operational problems, the proposed new forms of standards based on lithium-ion batteries to carry out mandatory safety certification, in addition to testing the final product, the authentication methods should also include product design and process review, supervision of the manufacturing process content and reference to quality system certification practices, establish a regular review and random sampling of the system, so will ensure that the maximum nikon d40 vertical-grip could be carried through standard content and implementation.

Lithium-ion Laptop battery safety
Standards should be appropriate means to seek and establish product safety and performance of the best combination, if it is not simply focus on safety, of course, the more stringent requirements as possible, but the overall technical level of the product restrictions, the better the security often means more poor electrical performance levels canon eos 350d vertical-grip.
Lithium-ion battery performance level is the most advanced and fastest growing commercial chemical power, and become mobile phones, laptop computers, digital cameras and other high-end portable consumer electronics products matching the power of choice. But its structure and principles of weakness, frequent occurrence in recent years, lithium-ion battery explosion wounding or recall of products due to security risks and other incidents, lithium-ion canon eos 400d vertical-grip safety has become a hot topic in national life, with the attendant safety standards for lithium-ion battery and related work has also become the focus of attention of various parties.
China Li-ion batteries to be coordination between the various standards
Current domestic and international basic safety standards for lithium-ion batteries are in line with detection-based standard, that standard provides short-circuit, over canon eos 450d vertical-grip charge, over discharge, vibration, shock, extrusion, impact (drop), hot-box, low atmospheric pressure, temperature cycling and other electrical , mechanical and environmental aspects of the pilot project, to simulate the battery in normal use and foreseeable misuse of the time of application, to ensure that products in these cases, security. This standard form has the advantage of clear criteria, operability is good, just for the finished battery to carry out laboratory testing to determine whether you can meet the standards, the disadvantage is that can not be fully effective in protecting the product quality and reliability, because the security of a product performance is an integral aspect of product design and manufacturing processes formed and established, the current standard of evaluation subjects with this biased, in addition to safety tests are destructive tests fujitsu lifebook c2210 battery, can only be conducted using samples taken, this method itself There are also a certain degree of risk probability.
Contrast to the standard can be seen at home and abroad, China’s safety standards for lithium-ion batteries lack of overall planning, basic fragmented. On the one hand between the state and industry standards of 2, as well as a lack of coordination between various industry standards, there is a certain cross-standard objects fujitsu lifebook c2220 battery, repeating the other hand, there is no uniform standard of guiding ideology, both simple safety standards, including the electrical properties have , environmental performance and safety performance applicable to all the demands of the general norms such as the nature of standards. In contrast, the same organization within the system of foreign ideas and standards in the work of inter-relations are more unified, coordinated, such as the IEC for the safety of their products a separate standard-setting, other criteria such as product specification electrical properties of the total, and other requirements, safety requirements direct reference to safety standards; IEEE are developed for different purposes, including security requirements, respectively, including general specifications of products fujitsu lifebook c2230 battery.

Recently, U.S. researchers are jointly developing a tiered solar thermal hybrid solar cells, combied solar photovoltaic xps m1730 battery and theof thermoelectric materials to absorb two different forms of solar energy from light and heat . Meanwhile, the U.S. Department of Energy also hoped that the solar cells made of tiles, replacing the now widely used wooden tiles, to contribute for the environment.
Currently they are working with Columbia University in New York. The researchers hoped that the roof solar panels for xps m1330 battery solar thermal hybrid solar conversion efficiency can reach 12%, although the efficiency is not high, but considering the low cost,it is still attractive.
At present, models is produced: a photovoltaic solar Sony NP-FC11 cells is under the outermost layer of protection in the solar panels , followed by the researchers referred to as “functional upgrades sandwich”, and thermoelectric materials is composed of the plastic tube . the cold water go into Plastic Header Pipe and cooling panels to play the role of outflows into the hot water heating for people to use. the bottom of the cell plate is in the plastic tube below : plastic strengthened stories.
Photovoltaic solar Canon BP-511 cells convert solar electromagnetic radiation into electricity, while the thermal layer of solar thermal energy will be converted into electricity. Researchers presented, plastic pipe “feature upgrades sandwich” plays an important role in the whole hybrid solar panels, especially in the summer, the solar battery for Sony NP-FC11temperature is too high, the conversion efficiency becomes low, this time The role of plastic pipe cooling device will be very obvious.
Right now, in addion to the test from the laboratory at Columbia University, the xps m1530 battery will be tested in a roof area of 6.4 square meters of Douglas College (FDA) n constructio of New York, . The researchers also calculated the cost of the technology to generate electricity, which is the most basic standards to determine that a new energy technology can compete with fossil fuels,
These are the first stage of the experiment. If this phase is successful, researchers will be 6 months into the second stage: obtain one million U.S. dollars from the Department of Energy , in a year the solar Canon NB-2L cells technology was further improved. After the third phase is likely to cost 10 million U.S. dollars for the commercial production of the technology.
U.S. Department of Energy said they were very supportive of the plan. Solar cell for Canon NB-2LH has not been able to penetrate into the market, mainly due to the initial high cost, conversion efficiency is low, but the solar thermal hybrid rooftop solar panels are part of the building’s surface, and the efficiency has been improved.

By the influence of international financial crisis, the global semiconductor and consumer electronics industry slowdown. Among them, the semiconductor industry, annual sales revenue fell by 2.8%, the size of the consumer electronics industry increased by only 0.94%. However, the global solarDell xps m1730 battery industry has continued for five years of high growth momentum, and output continued to grow substantially.
Global solar Canon NB-2LH cell production capacity increase 83% compared with 2007, reaching 13GW; solar cell production grew 35% ,reaching 4725MW; PV installation growth is up to 35% compared with the previous year, reaching 3962MW; solar cell market reach 15.9 billion U.S. dollars. In solar cell applications, the 2008 installed capacity of solar cells in Europe accounted for 75% of the world’s installed capacity, Germany occupied the world’s installed capacity over 50%. In the past 15 years, the global PV industry growth rate is 25% in average .
Solar photovoltaic industry has been able to maintain high growth momentum, due to solar cell energy is the world’s new energy development as a renewable clean energy.
The EU Joint Research Center study shows that in the future world energy mix, renewable energy, especially solar energy photovoltaic power generation will account for an increasing share of solar cell for Sony NP-FC11, by 2030 it will account for 10% of the global energy mix to 2050, this proportion will increase to 25% by 2100 ,and will reach 64%.
On the other hand, governments attach great importance to PV industry, andsee it see it as the important step to cope with the international financial crisis and cultivate new economic growth point. Among them, Japan’s resumption of solar Dell xps m1330 battery energy policy, Prime Minister Taro Aso announced that by 2020 the size of Japan’s solar power generation would be 20 times higher than the current expansion. Obama’s New Energy the U.S. government will boost the U.S. economy as the main starting point, and plans to invest 150 billion U.S. dollars over the next decade to fund new energy research,especiallly the solar cell for Canon BP-911 . The Australian Government announced in May 2009 will spend 1.05 billion U.S. dollars to build the world’s largest solar power plant, and estimated that the project’s future could be powered 1000MWp.
At present, China is the world’s largest solar cell producer, and has 11 PV overseas listed company, in 2008 production of photovoltaic cells tablets is 1.78GW, ranking first in the solar Casio NP-20 cell area world, accounting for 26% of global production.
However, with the largest manufacturer of solar cells in sharp contrast, in 2008, China’s solar photovoltaic capacity is only 34MW, only 0.57% of total global installed capacity, in addition, huge gap exists between production and demand,coupled with industry as a whole lack of core technologies, it has also led to China’s excessive dependence on foreign solar Panasonic CGR-S003 cell industry.
In this context, in order to make the domestic PV market to achieve a major development, from the enterprise level, should step up product development,and improve the conversion efficiency of solar cell for Canon NB-4L, reducing product cost.
From the government perspective, at present, solar photovoltaic industry in the development of China country’s policy efforts and the implementation of the scope of subsidies has been further improved, particularly the solar Olympus li-10b cell industry’s policy has been further strengthened.

Recently, the New Leader Battery Co., Ltd. overcome technical difficulties, it fill gaps for the invention of the world in the production of mercury-free buttonSony NP-FP70batteries,it has made tremendous contributions for environmental protection in China and the world .
As a battery-producing country, China’s battery (such as :Kodak KLIC-8000))industry occupied the world’s output of more than half of the battery in 1995 . However, due to the battery prior to containing excessive levels of mercury, which we usually refer to the mercury, leading to environmental pollution and poisoning, making battery life safety issues stood out.
And a high using frequency of thePanasonic CGA-DU21 battery and universality, it maks the threat of mercury-containing batteries become more prominent. It is reported that a micro-mercury alkaline button batteries contaminated water is 60 million liters of drinking water,it is equivalent to the amount of a person’s life. Although in 1995, the United States and Europe have issued a ban on the sale of mercury-containing batteries with the relevant provisions, and it clearly defined alkaline zinc-manganese batteries can not be added mercury and mercury content of no more than 0.0005% of total Kodak KLIC-7004 cells, but because the world has no technology to produce mercury-free button batteries for button cells can only allow mercury content is no more than 2% of the total mass of the battery.
In other countries, well-known battery manufacturers of mercury-free button cell mercury-free overtaken by a large number of studies more than a decade in Japan and the United States and Europe and other(take the Dell xps m1330 battery, for example) . However, because there are technical problems not to be resolved, so there is no one company which can successfully produce mercury-free alkaline button batteries, resulting in mercury-containing alkaline button batteries has been used in the global market . Button cell are producted and used 1 billion each year , so that China and the rest of the world people are still faced with the danger of mercury exposure.
The problem with the new Canon NB-2L Battery Co., Ltd Lida invention can be resolved.October 3, 2002, the new Leader for the “mercury-free alkaline button batteries” utility model patents successfully been authorized. In order to avoid patent issues encountered in overseas markets, the company again sync have applied for a number of the patent in the United States, Germany, Britain and other EU countries. However, China’s mercury-free button batteries for Dell precision m90 series battery are quite bumpy road. Over the years, as competitors have mentioned many times repeated the request is invalid, and no mercury button batteries 10-year patent protection period is about to expire, the ultimate fate of the concern of the patent.
China Battery Industry Association believed that is a “landmark” of technological progress for mercury-free button cell ,Dell precision m series battery industry to the world . U.S. Natural Resources Environment Association has also issued a letter to the China Battery Industry Association, and praised the newly developed non-Lida’s tribute make a major contribution to global environmental protection .
