We often see the 50$ original Dell laptop battery or Apple battery in Ebay. We are also asked about that : your battery is a original battery or not. You should realize that : the battery with the original Brand logo maybe not the original battery.

According to my 5-6 years market experience of laptop battery industry , http://www.battery4.us share some battery purchase note with you.

1. Now the laptop battery market is confusedly. Many low-cost “original” laptop batteries flooded the market. Most of these batteries are the original renovation battery (using a low-quality cells); the same pack with the original battery, no protection battery quality; Some of it is a true original stock battery, but most of them are produced for a long time (even more than two years).

The battery performance greatly reduced, as we all knows laptop battery is a consumable items, lose the performance even in stock; And there is no real brand new original laptop battery in the market, because battery manufacturers will be asked to produce the detail terms number battery by laptop manufacture, according to the amount of customized. The original laptop battery has an official one-year warranty, the market prices are mostly in the $150-200.

2. We all know, the lowest-cost maintenance approach to repair laptop battery (as Lifebook T4220 battery ) is replace the cells. Note that this is the least, sometimes you may have to replace protection board. A good imported batteries cell such as Sanyo, Sony, Samsung and other brands are 5.0$ or more in the market, high-capacity of 6$. Replaceme a 6-cell battery will takes about 35$ dollars or more.

Therefore, we can estimate the original laptop battery Price: 6 cell + battery protection board + enclosure + test fee + R & D costs + packaging + transportation + labor costs + a series of warranty after-sales and other costs, original laptop battery ex-factory price at least 60$, so You should carefully select these 40-50$ “original” Toshiba laptop battery in the market .

3. The main difference between High-quality and low-quality laptop battery Cells

I make the laptop battery as example to explain the diffenence for everyone. There are three kinds laptop battery in the market as following:

1. An original laptop batteries, good quality, need not any evaluation.
2. The famous brand laptop batteries like http://www.battery4.us, high quality and excellent price (the people’s favorite kind laptop batteries).
3. Waste batteries and “original batteries” gave as a gift when buying laptop, usually only stand 2 hours or less. Because these two kinds batteries capacity failed to reach the nominal capacity of standby time. So it is the worst laptop battery (Dell Inspiron 6000 Battery).
4. The replacement battery between 60$-100$ in the market. The battery can standby for 3-4 hours as original battery. But after used abour 10-12 months. The battery capacity reduced a lot or even scrapped. Although it can achieve the nominal capacity and the same standby time as original battery. But the other properties of the battery such as the battery charge and discharge times, the battery anti-aging properties simply can not up to standard. So it can only use 10-12 months.

Most of the 3-6 warranty months warrany “Original battery” and “OEM Dell XPS M140 Battery ” on the market are made of neutral batteries: It achieve the use of nominal time, but it is difficult to achieve the standard charge and discharge times, battery aging fast, average life between 3-6 months. (so they can only guarantee the battery up to six months).

In the end if you want to buy the high quality cheap price battery, just buy the 1 year warranty battery replacement in http://www.battery4.us/. Do not buy the “6 month or less warranty Original battery” in Ebay. As I know I saw many “original sony VGP-BPS8 VGP-BPS9 battery” in Ebay.

The company said that for this power plant to be developed, the company plans to use the latitude d820 battery for the electric car designed for a combination of ceramic storage technologies, polymer lithium-ion battery technology. This technique is safe and good, small size and high cycle stability and so on.

R & D projects as a first step, the company plans to start build a power one megawatt of electrical storage devices in the power station of Saarland in western Germany , the required storage capacity of the latitude d830 battery is about 700 kilowatt hours and the volume is only a power or hybrid electric vehicle battery 40 to 50 times. In theory, if the electrical storage devices charge and discharge is once every 15 minutes, it can ensure that 4000 families a year to power.

EVONIK chairman said that the new vostro 1500 battery and apple a1185 akku.once successfully developed, it will be able to solve the introduction of wind and solar power to the grid caused by power supply fluctuation. Industry experts pointed out that only German on the scheme renewable energy generating capacity will be increased to half of the total generating capacity by 2050, other EU countries will also be a growing number of wind power and solar power supply network. This gives renewable energy storage and transmission technology, higher and higher requirements. Experts predict that the future of advanced electrical storage devices will be billions of euros each year a huge market.

Zinc-manganese batteries is divided into cylindrical shape (with “R” indicated) and non-cylindrical battery (with “P” indicated) two kinds,according to their size and electrochemical system named after the battery,like the Samsung sb-lsm80 battery. However, prior toOctober 1990,a non-cylindrical-shaped battery is divided into shut-ping (using the “F” indicated) and side (moment) form (with “S” indicated). Dimensions mentioned here do not mean a whole cell (battery) form factor, but one of the single cell (cell) form factor. For example, the battery 6LR61 the overall shape is square (moment) form, but that one of the single cell LR61 is cylindrical, so the battery model is based on the shape of single cells “R” named. Shut by several cells in series flat-shaped zinc-manganese composite made of single cells, often referred to as stacked-type battery.

Neutral zinc-manganese batteries can be divided into cardboard paste-type cells and batteries,for one thing ,the Sony np-qm91 .according to the difference between isolation layer ; according to the level of battery capacity,they also can be divided into ordinary products (S), high-capacity (C) and high-power (P) 3 grades, but the recent IEC standard battery has been canceled C-, neutral zinc-manganese battery-free electrochemical system code. Alkaline zinc-manganese batteries combined in form and pre-electrochemical system, code-named code-named “L” said.

Zinc-manganese battery is the oldest of the original battery for Canon lp-e5 . the battery is still the leading civilian products. With the continuous development of science and technology, neutral, alkaline zinc-manganese batteries will gradually be replaced by zinc-manganese batteries. when the IEC standard is currently changed ,the battery C-type was removed .

1. Choose the “National Inspection-free”, ” famous brand” (such as Samsung sb-l160 )logo and the local brand-name batteries battery products, the quality of these products have a certain protection.
2. According to the requirements of electrical appliances, select the appropriate cell types and specifications of size and power apparatus ,and according to the size and characteristics of power, purchase equipment for electricity battery.
3. Pay attention to checking the battery production date and shelf life, buy the recent production of the battery (for one thing ,the new Nikon en-el7 battery), the new battery have good performance.
4. Pay attention to checking the appearance of the battery,should buy packaged refined appearance neat, clean, no signs of battery leakage.
5. Pay attention to the battery symbol, the battery should be marked with the production mark the make, battery polarity, the battery model, nominal voltage, trademarks, etc.; sales package (such as two heat-shrinkable, or four heat-shrinkable, or hang tag card ) It should have the Chinese factory, manufacturing date and shelf-life or shelf life of the deadline marked the implementation of the standard number. Purchase of alkaline zinc-manganese battery ALKALINE, or whether one should look at models LR words.
6. Due to mercury batteries harmful to the environment, in order to protect the environment, the purchaser should select the label marked “mercury-free”, “0% mercury,” and “no added mercury” indication of battery,take the Nikon en-el3e for example .

Should pay attention to the use of batteries :

1. Electrical appliances and battery contacts should be clean, if necessary, wipe with a damp cloth until the dry loaded correctly marked by polarity. When loading the battery to see for the polarity ( “+” and “-”) to install an extremely important ,and should be the specification requires the installation of electrical appliances with the use of the recommended batteries; do not follow instructions required will lead to equipment failure, damage to electrical appliances and / or battery.
2. Should also replace all batteries in a battery, do not mix old and new batteries together; the same model but a different type or brand of battery electrochemistry do not mix, such as Canon nb-4l and Canon nb-3l , and otherwise it would be a set of batteries in use in some of the battery over-discharge state, thereby increasing the possibility of leakage.
3. Can not heat for a one-time or charge the battery for recycling, or they may explode.
4. Can not make the battery short-circuit to avoid battery leakage and resulting damage to the heat generated by insulated packaging.
5. Electrical appliances should be removed from the battery for a long time without using , the power should be closed after using to avoid the battery going on to discharge its internal chemical reaction took place which led to leakage of the negative.
6. Used batteries for sony vgp-bps2a should not arbitrarily discarded, as far as possible separated from other garbage running.

Expert introduce how to safely use mobile phone:

A manufacturer who told this writer that the battery safety problems exist not only mobile phones. At present, all kinds of batteries (such as Fujifilm np-120 )has become a modern life, basic equipment, mobile phones, portable computers, portable devices can not do without the battery, if the use of low-quality batteries or used improperly, these batteries have the possibility of an explosion.

At present mobile phone mostly used lithium ,Samsung sb-l320 batteries, Generally, there are three reasons of the battery explosion.

1. The battery itself, the reasons. Since the apple a1022 of internal defects, the battery does not charge itself does not discharge the case of an explosion.
2. The long-term overcharge batteries. Lithium batteries might generate substantial transient discharge currents in a special temperature, humidity and poor contact, etc. or the environment , triggering spontaneous combustion or explosion.
3. The battery for Samsung sb-l160 short-circuit. This is less likely. In addition, consumers put mobile on the high temperature or next to flammable materials ,it may also trigger an explosion.

Order to prevent the risk of further deterioration of the financial turmoil triggered deep-seated economic problems, the Fed announced an emergency rate cut this week in two 75 basis points, to a certain extent, eased the panic in financial markets filled with emotions, the world’s major stock markets have rebounded fujifilm np-95, after following the oversold Yang received. Despite the panic around the popularity to be a little relaxation, but the overall trend is still Zoudie zinc City Channel, lun 3 weeks straight zinc has dropped, the cumulative drop of 235 U.S. dollars / ton, the lowest point (2160 U.S. dollars / ton) touched the bottom of the support line (Zhou K chart, February 17, 2006 and November 23, 2007 low of connections); Shanghai zinc index fell for two consecutive weeks, the cumulative fall of 1618 yuan / ton, the lowest point (17,776 yuan / ton) are also the formation of the bottom of the support (17.6 thousand yuan / ton in the vicinity) stress test. Overall, zinc City last week, showed significant support will retest of the lows.

For the next week, zinc City, the trend caught on because canon nb-6l of their multiple negative factors, will continue to support the wishes of the performance of retest of the lows. Multiple adverse factors are beyond our focus is: the continuing turmoil in the macroeconomic environment; supply and demand data reproduce the excess pressure; investment funds, the formation of bottom pressure of a high position.

First, while the Fed’s emergency rate cut to a certain extent, to prevent the U.S. economy sliding into recession may fast, but monetary policy was helpless further exacerbated by global inflation. At the same time, investors are still worried that the collapse of the U.S. housing market has exposed the questionable mortgage casio battery , casio np-100 lending standards for the industry, followed by credit cards, auto loans and student loans could be the next troubled industry, which make the financial system and economically difficult.

Secondly, the China Nonferrous Metals Industry Association latest statistics show that in 2007 China’s zinc output of 3.714 million tons, increased 17.8% compared with 2006, the average monthly output of 33 million tons. Although the zinc price suddenly dropped from the primary and secondary smelters cut production starting in November or even stop production when compared, the market is estimated that in 2008 a quarter of the average monthly production will decline to 30 million tons, but the overall situation of the domestic surplus in 2008 to show greater pressure (07-08 zinc futures first annual report are described in detail sony vgp-bpl8 , sony vgp-bpl8a), while in 2008 the domestic regulation and control policy tightening will make the “China factor” strong demand growth in the supply of hard to arrival. Therefore, the excess pressure on zinc price to find strong support for retest of the lows.

Finally, the zinc municipal positions rising, while zinc prices have consistently fallen. This shows that most investment funds to see the empty zinc prices, see the empty pursuit of money and zinc prices will also seek a strong support base. From a technical trend of view, careful test of their ability to support LUN zinc 2000 (I pessimistic about the material in 1800 is expected to form a more powerful support), Shanghai zinc 16,600 yuan / ton (pessimism 15,000 yuan / ton sony vgp-bps9). Operation, I believe that Shanghai more than one-zinc reduction or leave the air rallies admission alone. Operational strategy, risks remain due to shock, short-term operation is appropriate.

“The world is flat canon nb-2lh, lithium battery industry chain are mutually beneficial and reciprocal, circular links.”

Live in a global economy, communications zero distance of the “global village” where we have to look at the world, a world vision to seek the cause of lithium.

South lithium creation and development of the forum, no doubt benefited from the South China lithium battery sector, especially the South China several Chinese leader in a global outlook and lithium pioneering spirit. The face of an open world, including South China, including B & K Technology lithium enterprises to actively canon nb-3l search for specificity based on industry marketing and industry connectivity strategy, to making China to explore business development and progress of the Pan-lithium and lithium and the world at the Pan-Electric industries face to face opportunities for exchanges.

To 2006, the first, in 2007 the second session of the South China successfully held the Forum, after lithium, as lithium in South China Forum on first organizer – B & K Technology farther cast their sights higher canon nb-4l, and the South China Lithium forum topics from the “China Lithium electricity, from manufacturing to the creation of “Innovation for the Pan-lithium electric industry’s” new inventions, new technologies, new applications, lithium electrical energy revolution. ” Electrician in 2008, the industry’s first lithium-concussion – the third High Level Forum on South China Lithium (International Year) team elite guests, including B & K’s on the kind invitation of the world’s elite eight-nation lithium technology, China’s lithium battery industry, consumer goods, the use of the field leaders and China’s top manufacturer’s at the helm lithium leader of the majority of China’s electrical industry personnel and even Lithium vision Miao Xiang of China’s electricity sector, the world’s lithium-lithium lap a pan-industry, world-class canon nb-5h exchange platform.

B & K Technology Group, as China’s lithium industry pioneer and one of the leading actor in China’s lithium battery industry, an indispensable role. B & K, founded in the late 20th century technology, the erection of lithium power industry under the guidance of the spirit of the national banner, in nearly a decade of development and production of lithium-powered products, the products involved in used cell phones, Bluetooth, DVD, model aircraft aluminum lithium canon nb-5l batteries and other fields batteries, flexible packaging polymer lithium battery. In recent years, the rapid development in previous years, based on B & K Technology also created a sub-market, all kinds of lithium products, including solid-state polymer lithium battery, miner’s lamp battery, lithium batteries for electric vehicles, power tools such as cylindrical lithium batteries the use of lithium series of new materials, new technologies, products and applications during this period nearly 50 core technology patents, fully demonstrated its lead in the lithium industry, new concepts, research and development of new products, guide the development of the industry and to conquer new markets, a strong field实力. This same time, the B & K technology to good momentum of rapid development, BenQ has won national, provincial, and development of preferential policies for the honor, which will include the second half of 2007 was listed on the Shenzhen municipal enterprises and entrepreneurs plate special fund for the company market development plan in 2008 has laid a solid and important foundation sony vgp-bps8.

There are gaps on the need to have progress, progress will certainly be seeking the next step in the development of science and technology firmly in mind Banke “broad decision to heart, mind determine success or failure.” Banke dare to the development of science and technology the courage to connect China and the world of the pan Lithium-Ion battery industry, as the goal, through the South China Lithium forum as a platform, lifting China’s electricity industry in lithium power lithium sony vgp-bps8a battery industry in China, set policy, and then integrate into the world as a whole lithium battery industry in the wisdom of building our brand in China the world’s lithium, and look forward to more Chinese Pan-lithium enterprises, through this worldwide forum for the South China Li-ion lithium power industry platform, break through the bottleneck, to a world-class market and create a world-class brands leap forward.

“It depends on Yinshan a film to open the window into the river.” Seek a world vision lithium cause of cross-flow sea, a thousand sails compete.

To invite the world’s giant lithium lithium co-China study Chinese companies to test the thickness and width of the core of China, sony vgp-bps8b look forward to standing in the world’s forefront of lithium, which in China is the first time in the history of lithium.

A Japanese company canon nb-1lh has introduced a wonderful green rechargeable batteries. The cell shape and no different from ordinary batteries, but the difference is that it is a by “drink” to recharge the battery. The battery inside the material is aluminum and magnesium, they will join the liquid with the chemical reaction, resulting in generation of energy. Therefore, to give this rechargeable battery does not require any equipment, only through a special syringe to add some liquid inside the battery can be, whether it is pure water, fruit juice, even beer, can be used to charge it.

The international metals markets this week by the obvious impact on the global financial market turmoil, weekly U.S. banks due to sub-prime mortgage giants have a huge impact of bad debts sony vgp-bps9, which makes the global financial markets experienced a major earthquake, but the Tuesday night accident in the United States dropped 75 bank interest rates, but also to enable the financial markets rebound retaliatory, as in a non-ferrous metals, zinc can be spared.

In addition to the Shanghai zinc limit down there Tuesday, the fluctuation range than the outer disk is small, but the heat that the short-term intraday trading on speculation rather, Wednesday and Thursday there were 50 million lots more massive, synchronized position there was a marked recovery. Shanghai zinc trading this week, also features in recent months, the contract re-emergence of long months of premiums (in the month between February and April the difference sony vgp-bps9/b , sony vgp-bps9/s for example, to close the week +90, while the last week, compared with -220) This may be Chinese New Year holiday is subject to the effects of antecedent being prepared library strong Suozhi spot.

Ben Stein likes catching picture-perfect moments on his digital camera but has one big frustration. “The thinkpad x40 battery life is not reliable,” he says. “I never know when it’s going to die.”

But now, engineers are unveiling a new battery — called Oxyride — that boasts almost double the power and life of regular batteries.

“If you use this battery in a digital still camera, you’ll receive — minimum — twice as many photos as compared to alkaline batteries,” Brian Kimberlin, of Panasonic Battery Group in Secaucus, N.J., tells DBIS.

Using a finer, more concentrated material inside the battery, engineers have developed a way to fit more electrolyte — a key ingredient for carrying electricity — into the same size battery cell. The new thinkpad x40 battery is packed with more power and longer life.

Kimberlin says, “We’re putting a little more juice in the thinkpad x41 battery, and the components are stronger and better.”

The new thinkpad x40 battery also produces a higher voltage. With it, flashlights shine brighter, and camera flashes recover quicker.

“If something lasted twice as long, that maybe means I’ll have half as many worries,” Stein says. And for him, using it may mean not missing any more great shots.

The Oxyride battery is also ideal for music players and digital games. It hits the shelves this summer, but will cost about 20 percent more than regular alkaline batteries.

BACKGROUND: Matsushita Electric Industrial has developed a thinkpad t400 battery that delivers 1.5 times the power of a regular alkaline battery, and is cheaper than the lithium batteries used in many electronics devices.

HOW IT WORKS: Any battery converts chemical energy into electricity. There are two ends, called terminals: one is positively charged, while the other is negatively charged. Opposite charges attract. So when these two ends are connected by a metallic wire, electrons will flow from the negatively charged terminal to the positively charged one. This flow makes an electric current in the wire. The current can be used for power, simply by attaching a light bulb, for example.

A battery continually produces new electrons at the negative terminal from a series of chemical reactions. So the thinkpad x40 battery essentially acts like a pump, pulling electrons from the negative end of the conducting wire and pushing them into the positive end. A battery only holds a certain amount of reactants, and once those are used up, there can be no more chemical reactions, and the battery is dead.

ADVANTAGES: The voltage of a battery varies depending on the kinds of metals and chemicals used. Duracell and Energizer brands use alkaline combined with zinc and manganese oxide. Laptop computers and cell phones use lithium-ion batteries.(thinkpad t400 battery,thinkpad x30 battery) Oxyride batteries maintain higher voltage and output longer because they use oxy-nickel hydride, along with finer grain graphite and manganese dioxide. The company has figured out how to blend these ingredients so more can be stuffed inside a battery. An Oxyride-powered digital camera, for example, can take twice as many pictures as one powered by a standard lithium battery.

1. The development of new electrode materials and other battery components .

Modification of other SOFC ,Dell inspiron 1525 battery components allowed the system to optimize the structure to meet the medium-temperature fuel cell operation; development of the temperature under the conditions of a certain activity in the same time, they met with the electrolyte performance matches the electrode material; to improve the micro-electrode structure. One nano-electrode is a feasible route. It has small particle, increase the three-phase industry (catalytic center) in length and electrode / electrolyte contact area, greatly reducing the interface resistance; also can reduce the electrode thickness, so that gas is more easily spread to the three-phase interface, decreases due to electrode concentration polarization caused by reducing the efficiency of the Canon bp-2l12 battery.

2. Proton conductor, and protons – ion mixed conductor electrolyte development.

By a proton conductor as electrolyte, the water is produced in the oxidizer side, so there will be no oxygen ion conductor as electrolyte, as, after the fuel Dell inspiron 1526 battery reaction required to remove water from the fuel. When using methane and other hydrocarbon gases, only the pyrolysis of these fuels can be considered to be the hydrogen fuel cell proton conductor of fuel, while the remaining part of the restructuring could serve as a useful product is retained by the akku reaction such as ethane, after re – availability of ethylene. Some electrochemical reaction must use the proton conductor material. Such as: industry H2S emissions to deal with this fuel Dell inspiron 1720 battery can generate electricity at the same time, to be a useful by-product of S2.

3. Study the mechanism of proton conduction and to develop sufficiently in the conductivity-temperature proton conductor.

This is a promising Dell inspiron 1721 battery research direction. It should be said, proton – ion mixed conductor is a new solid electrolyte, to find the material itself is a new challenge, which for the deepening of our design of new SOFC, has a special significance.

4. New concepts and new methods.

The recent emergence of single-chamber fuel Dell inspiron 1521 battery is a new concept. Despite its many shortcomings, but it is a worthwhile research direction. Its main significance lies right to our future design of the battery to give a useful inspiration. For the electrode material structure, the traditional electrode majority of asymmetric electrodes, ie cathode and anode materials used in the different. If you are using symmetric electrodes, the Casio np-100 battery performance will be? This is worth studying. For the cell preparation methods, the method currently used mostly expensive, finished product rate is low. Research and development of soft chemical preparation routes, the introduction of mild conditions, the material preparation methods, is bound to have a strong competitive edge.
