Dell inspiron E1505 Laptop Battery

laptop li-ion battery separator be more efficient

As international oil prices high,adapter for laptop more and more car drivers to take into account in determining the fuel economy, which directly led to a worldwide market share of hybrid vehicles rose. Expected that by 2012, U.S. sales of hybrid cars will be increased to 100 million. In order to meet the demanding needs of hybrid cars, laptop battery is key components – membranes must be improved, improve energy efficiency, thus providing more power for this vehicle, the courage to deal with the challenges of the world’s energy shortages.

The important role of the diaphragm is small

Due to the high energy density lithium batteries(xps m1330 battery,latitude d830 battery), long cycle life, light weight, small size and other characteristics, but also has a safe, reliable and can quickly charge and discharge, etc., to become the new power technology in recent years, the research hotspot in the field of high-energy and high-power reserved popular. In the lithium battery structure, the inner membrane is a key component of the. Diaphragm made of plastic film is able to isolate the battery positive and negative, in order to prevent short circuit; also be in the battery overheating, through closed-cell function to block cell in the current conduction.

Chemical’s chief polymer scientist said Bai Peide, lithium battery separator battery costs account for the cost of a / 3. Membrane determines the performance of the batteries(gd761,kd476) interface structure, resistance and so on, a direct impact on the battery capacity, cycle performance, and security features such as, high-performance membrane in improving overall performance of the battery has an important role. At present 60% to 70% of the membrane market, mainly in wet bi-oriented process, because the wet, bi-lateral vertical stretch more evenly balanced. It is mainly used for high-end diaphragm wet, dry method has been applied in the low-end products.

A huge global market volume

Global Li-ion battery production in the past 15 to 17 years has maintained an average of 10% to 20% growth rate from 2001 onwards, the average annual growth rate was as high as 40%. Rapidly growing lithium battery market, in addition to watches, and other one-time button-type batteries,inspiron b120 battery and inspiron b130 battery, as well as secondary rechargeable lithium-ion batteries. In addition to the current lithium ion batteries are widely used in daily well-known mobile phones, notebook computers and MP3 and other digital electronic products, in electric cars, electric bicycles and some other high-power batteries have also been started.

At present, countries are scrambling to develop electric cars, hybrid cars will need batteries to provide power, as a pure electric vehicles matching power supply, lithium-ion power supply for its outstanding performance, is becoming the core of the power type. As the hybrid line with today’s national energy development needs of a large environmental protection, consumption growth must be greater than 20%. Reason to believe that lithium batteries will eventually occupy the dominant position of secondary battery market, as its key components, the lithium battery separator huge market capacity.

Personality development to improve energy efficiency

Battery separator is mainly the development of lithium-ion batteries(inspiron e1705 battery,inspiron e1505 battery) with the evolving needs and continue to develop, from the volume point of view, lithium-ion batteries are moving in the small and large two distinct direction. In some, such as mobile phones, digital cameras and other electronic products, in order to meet the beautiful, easy to carry the demand on the battery batteries battery factory has been very small. In pursuit of high energy density, in the small size of the electrode can accommodate more material, the battery manufacturers want to divide the thickness of the thinner the better. Smaller diaphragm is a challenge because of the need to do a thin membrane, but to be able to maintain the original battery capacity, cycle performance, and security features, and greater power, the design easier.

By contrast, in electric bicycles, electric vehicles and electric tools used by power batteries, in order to obtain high-capacity, high-power, usually a battery need to use dozens or even hundreds of batteries to concatenation. Because lithium batteries have the potential explosion hazard, the safety diaphragm is important. Due to become bigger and bigger, technically demanding more efficient and reduce greenhouse gas emissions, power stronger.

Bai Peide convinced, lithium battery separator according to the different needs of different customers to develop targeted products, which divide the future trends. Although the divide is mainly single-market products, but Exxon Mobil has been able to put different materials on different membrane layers, each layer with different formulations vgp-bps2c battery of solvents and raw materials to multi-layer co-extruded to produce hot-melt thickness and diameter of hair, similar to divide and thus produce different properties of products, Bai Peide predict the future trend of multi-layer membrane is also obvious.

Still need to speed up the development of China

According to the Irish market research firm recently issued a lithium battery market forecasts show that China’s current production of lithium batteries as the world’s largest. In the global lithium battery production, the Chinese mainland accounted for 16.9%, China Taiwan region accounted for 6.9%. According to China’s Power Industry Association of Chemistry and Physics, Statistics, 2007 China Li-ion rechargeable battery production reached 1 billion.Affected by China’s lithium-ion battery separator market-oriented development has also begun to take shape, now showing a very good momentum of development. In accordance with the battery output of 1 billion is estimated that consumption of each diaphragm 300 million ~ 500 million square meters between the market value of 10 billion to 1.5 billion.

However, China’s research and development of lithium-ion battery separator got a late start, lithium-ion thinkpad t60 battery separator still mainly rely on imports, leading to the market price remains high. At present, only Japan, the United States and a few countries have a lithium battery separator production technology and the corresponding large-scale industry. China’s domestic market, over 80% of diaphragm were the United States, Japan and the occupation of imported products, domestic divide is mainly in the middle and low-end markets.

The future, China needs to strengthen the industry, academia, research inputs, to develop research achievements with independent intellectual property rights, breaking the Japanes and American enterprises in the membrane industry, technological monopoly; the other hand, enterprises and research institutes should strengthen cooperation, speed up the results The industrialization process of transformation.

Inspiron E1505 Dead Battery problem

I bought the Dell Inspiron E1505 about two years ago. Like so many of the others who bought this laptop, my Type gd761 , KD476 , 85Wh battery died just after the one year mark. The problem started when the battery light began flashing. The battery has a usage button on it which indicated that the battery was fully charged, however, every time I put the battery in the laptop, the light started to flash again. I found dozens of blogs and tech sites like this one where Dell users have voiced the same issues with this computer and its battery. (Just enter, “Problem with Dell Inspiron E1505 Battery” into your browser to see what I mean) All Dell will offer as a solution is to tell me to buy a new replacement battery.So I bought a new one on http://laptopsbattery.us/dell-inspiron-e1505-battery.htm

This battery started off incredibly strong, kept my Core2Duo Inspiron E1505 going for a solid 4-5 hours per charge, enough time for me not to need the charger as I studied on campus.

This Dell Inspiron E1505 battery–9 Cell Replacement Battery features lithium technology, which ensures maximum battery life and maximum power. It also features no memory effect that lets you recharge partially drained batteries without reducing performance.

The overall performance of this laptop was marginal at best, despite what anyone else thinks of it. My older Inspiron 1100 is a much better laptop and has never had any issues with it’s battery. I was enticed to buy the more expensive battery when I got the E1505 because the Dell wen site said it would last longer. Obviously, that is not true. Dell Customer Service will not take ownership of the problem that I am many others have had with this laptop. I’ve bought five computers from Dell in the past seven years or so. The E1505 was the latest purchase. My older Dell computers all work much better than the E1505. Personally, the E1505 is a useless piece of junk to me, if I cannot use it as a portable computer. Instead, it remains landlocked to a wall outlet if I want to use it.every year for a new inspiron E1505 battery. I either expected my money back, a free battery or a comparable replacement for the E1505, any of which I know I will never receive from Dell. They don’t really listen to their customers. I used to be a big Dell supporter, but not any longer. Dell sucks as far as i am concerned! My next system will come from HP. I won’t buy anymore Dell products and I’d suggest anyone else to avoid buying a Dell computer unless you also want a headache, or you enjoy being ignored by Dell when you have a problem with their products.

China lithium batteries lose a fight to defend a patent bureau

China lithium batteries lose a fight to defend a patent bureau

In the first half of this year, this newspaper since 3114, the four successive interest of the University of Texas and its commercial mandate Hydro Quebec, Canada, Phostech alleges that the U.S. battery maker A123 (GEM), Inc., Vaillant (Valence) Company Infringement lithium ion phosphate patent dispute. This series of reports have caused widespread concern outside the industry. Today, lithium ion phosphate laptop batteries on the topic of the patent once again affects the electric car industry’s nerves, but the protagonist of the incident replaced by China.

On lithium ion phosphate in North America, playing a flurry of patent lawsuits when a lithium ion phosphate battery patents to defend the war broke out in China. DVD patent pool

To avoid recurrence of this tragedy, our country more than the battery(GD761, KD476 ) companies and research institutions are positive actions, to collect evidence to prove that Hydro Quebec and the French research center in China last year, the application of phosphorus acid, lithium ion-layering carbon technology patents (now an exclusive license to the Canadian Phostech company) is invalid. However, the present situation, the Chinese side want to win, extremely difficult.
The success of foreign companies in China apply for patents

layering of carbon this year, China’s electric cars and motive power batteries forum is particularly high. In almost every forum, can see the shadow of Canada Phostech company representatives.

Not long ago, the fourth South China Lithium Power (International) high-level Technical Forum held in Shenzhen. Made a special trip from Canada came to participate in the forum Phostech Rice, CEO? Toston smiling. After the introduction of products and technology, Toston answered live audience on the patent question. He said: “In the United States, the Tribunal intends to recess for some time to continue to hear from companies such as our A123 lithium ion phosphate battery patent dispute. Last December, the European Patent Office rejected the Phostech the company’s lithium ion phosphate battery patent application(Dell inspiron E1505 battery ,inspiron 1501 battery) . We intend to continue to apply for patents, is expected to be approved in 2010. In addition, in Japan, we are also actively apply for a patent. ”

Toston Phostech talked about companies in the United States, Japan and Europe application for a patent case, but did not mention China, and I wonder if the wish to avoid. According to report, in 1999, the French scientific research center, Professor Michael? Oman and Germany invented the carbon-layering technology, solves the conductivity of lithium ion phosphate materials, poor problem. Subsequently, from Hydro Quebec and the French Scientific Research Center have applied for the patent. In 2008, the two institutions in the Chinese patent application is approved, the patent has been the exclusive right to use license to the Canadian Phostech company. Seize the high ground in the patent

after, Phostech actively explore the Chinese market. Currently, the company has opened an office in Shanghai. At the same time, its high-level frequent appearances in China, and actively promote the company’s lithium ion phosphate batteries and materials.

two patents can not by pass

Chinese Academy of Engineering, Li-Quan Chen told reporters, in the lithium ion phosphate batteries,dell battery inspiron e1505 and material field, there are two core technology patents can not be bypass, one of which is the layering of carbon technology patents, and the other is the carbon-thermal reduction technology patents. The former has applications in China, the Canadian company has the exclusive right to use Phostech; the latter owned by the United States Viagra can be company, has yet to apply for a patent in China. However, Viagra can be company has set up two companies in Suzhou — Vaillant Technology Co., Ltd., Takeyasu Energy Limited, are responsible for the production of lithium ion phosphate materials, and battery production(dell GD761, KD476). In order to seize the Chinese market, Viagra can be company does not rule out the patent on the trivial.

Academician Li-Quan Chen also told this reporter in a surprising thing: It turned out that Viagra can be company owned by the carbon thermal reduction technology patents, is entirely his students — Dong masterpiece.

2000, the Dong switched from a Canadian company to enter the United States Vaillant, serving as a senior research fellow. Prior to that, he has been the French National Research Center for Condensed Matter Physics Institute of Chemistry of Bordeaux and received a doctorate and post-doctoral study in the United States. In Vaillant’s work, Dong fully demonstrated the Chinese people industrious, intelligent character in just six years, he helped Vaillant companies in 28 countries around the world applied for the patent materials, lithium ion phosphate (Dong is the inventor , the property Vaillant companies).

However, things are unpredictable Dong was perhaps never imagined that today, these patents would become the Chinese battery (dell xps m1330 battery,xps m1730 battery)enterprises to enter the field of lithium ion phosphate battery barrier.

“At that time, I can think of their own materials, lithium ion phosphate formulations and preparation methods are written out and apply for a patent. Some of the patent, Viagra can be company already has a corresponding time technology, and others are under development, there are simply not begun to study. This series of patents is very tight, almost covering the manufacturing aspects of lithium ion phosphate battery is indeed hard to break. “talking about past events, Dong so right , told reporters.

want the patent is invalid, the Chinese side little chance of toppling

“in the lithium ion phosphate batteries and materials, China has absolutely can not be called art. There are few enterprises that Patent no problem, it is nonsense, and there are many complex issues to be resolved. If we say that, for the University of Texas and the A123 between other organizations such as lithium ion phosphate patent dispute case, we are somewhat indifferent manner of taste, then this a company in China with access to packet Phostech deposited carbon technology patents, as well as companies such as Viagra can seize the Chinese market to accelerate the pace of the patent problem has become very realistic placed in front of us, not be evaded. “a company official said the battery.

Is aware of this, these batteries(dell inspiron b120 battery,inspiron b130 battery) before businesses and relevant research institutions together to gather evidence, look forward to tear down barriers to multinational patents.

State Intellectual Property Office a staff surnamed Wang told reporters, “Patent Law” Article 22 clearly provides that a patent application at least have novelty, creativity and practicality, and no other substantive issues, in order to be authorized. By the same token, if you want the patent invalid, the State Intellectual Property Office shall review committee to pursue the invalid request has been authorized by the patent to prove there is no novelty, inventiveness or usefulness. If rejected, you need to bring an action through the legal channels to resolve.

The staff member also said that the best means of proof is to find a one or more previously public documents, and to compare the patent claims, xps m1330 battery,if the overlap, you can prove that the patent the lack of novelty. Corporate sources, and now they have found an open literature, but the arguments are not particularly strong. Once the proceedings, the odds are not great.

Chinese Academy of Sciences Institute of Physics, doctoral tutor Huang Xue-Jie said, after the U.S. Japan’s NTT paid 30 million yuan (equivalent to RMB) settlement, the only solution of the lithium ion phosphate material patent disputes. Many enterprises in Taiwan is to spend money to buy other companies to Phostech the right to use the patent. “If in the end, China and Japan, companies have to embark on the road to spend money on patent licensing, which is China’s ion phosphate lithium battery manufacturers would be a bad news, but also a sad thing.”

Dell Latitude D820 D830 Notebook Computer

The Dell Latitude D830 is the successor to the Latitude D820, a mid sized business notebook with a 15.4″ screen and the new Santa Rosa platform. Weighing in at nearly six pounds it tips the scales at the upper end of the thin-and-light category. Pricing as of this writing starts at $899, and like most Dell notebooks there are plenty of customization options available.

Features Overview

My Latitude D820 was configured with the following major options:

Battery maintenance and correct using

Battery maintenance and correct using

Laptop battery can be said that the most important source of inspiration. No batteries to provide energy, you can not complete the special requirements of mobile office. Then we can at best laptop in the hands of a mobile PC Bale. The laptop battery maintenance and use of skills has become a headache for most consumers the best thing.

A. In the purchase laptop battery after more than three consecutive 12-hour continuous charging, to prevent “memory effect”

Memory effect refers to the battery to withstand a long time after a particular work cycle, automatically keep this particular trend. Therefore, saying that if every time the battery(dell inspiron e1505 battery) charge only 50% of the time began to use, then the subsequent memory effect the battery will be the next times when the charge can only charge to 50% of the time on the “can not be recharged inside of.”

As the manufacturing process of the gradual improvement of lithium ion batteries,gd761,kd476,td347 etc. constant current charging method for deep-charging time of its control in 4 hours,Laptop battery is dead on the charge, every two weeks or a month’s time resting, will conduct a depth of laptop battery discharge, is to use battery-powered, no electricity and then used directly on the computer automatically shut down on it. However, the number of times the depth of discharge should not be too frequent.

B, using the AC adapter when the battery should be removed first in order to avoid the battery “full blast”

Currently on the market lithium-ion batteries used in laptops can complete 300 to 600 times of charging and discharging process, we can calculate what their own, and now on the market Centrino models of battery life time is normally more than the official data for 5-6 hours,inspiron b120 battery,inspiron b130 battery. Ben 4 models the battery usage time of 3 hours,Friends using the AC adapter when the battery get down and worried about is that if your are more left inside the battery power, plug in the AC adapter, the results of the results began to charge the battery caused by their own waste is a “charge number of times. “In fact, this worry is unnecessary, because the laptop battery power within the state certainly can not be hundred percent, so when using the AC adapter will definitely be completed charging.Notebook computers are designed with battery protection measures, such as IBM’s notebook only in the capacity less than 95% of the time will be charged.

The chance of battery explosion is small . However, May occur, lithium-ion batteries which are lithium batteries, a control circuit between them and the management board to complete the charge and discharge, if the control circuit to lose some of the features of the sensitivity of the original or direct failure, you can not be effectively control the current, internal batteries temperatures cause the explosion. Or the dell laptop battery short-circuit inside the batteries will explode.

C, the battery usage time did not meet the official standards, definitely the battery problem

If a friend who has reached the battery standby time less than “official battery using the standard,” then we can still be extended through a number of ways:

1,25 ℃ ~ 40 ℃ using a standard external environment, the use of lithium-ion batteries can reach the best condition, if the temperature is too high, not only run the notebook computer itself to slow down or even crash, but the battery in such an environment is also under the will affect its efficiency. So, as far as possible under the indoor environment using a laptop.

2, the less frequently used device is disabled. Usually when using the battery-powered best to temporarily disable the swap the unwanted interfaces, such as wireless network card, printer port, infrared port, 1394 Firewire port, etc., or would waste a lot of battery power,inspiron E1505 battery , the specific method is in the ” Control Panel “-” System “-” hardware “-” Device Manager “to find their own want to disable the device, and then click on” disabled “can be, and need to use the time to be” enabled devices “, is very simple. After disabling the use of results have been very obvious, you can save a lot of power.

3, reduce internal power consumption of devices. More and more CPU-frequency, high-speed hard drives will bring a lot of energy consumption and increased heat dissipation. Therefore, no special requirement, then the best use within the system or a third-party software to control the drive speed, do not open too many windows and programs in order to avoid CPU overload of work, so not only can reduce the battery power consumption, another can also reduce the bulk heat, in the “autumn tiger” there is the season, this is still a little benefit.

D, In starting laptop to charge the battery is very harmful

In the notebook, the previous design of some models is that if the use of battery-powered, then even if the plug AC adapter, books, or the use of battery-powered, dell gd761,kd476 battery.which means “can not be recharged into the” phenomenon of today’s notebook computers are not so The design of the dangerous, and when the plug when the AC adapter immediately shifted to an external power supply and began to charge the battery. So now there is no need for shutdown recharge.

E, long-term without batteries and leave it side

At present, many notebook manufacturers on the proposed user to control the battery power more than about 5%, this approach is to eliminate electrode passivation, since the laptop battery when the factory has begun to slowly self-discharge (to activate the battery thing has been in the workshop is complete).If long-term without the battery and AC adapter, if used, it is best left to the dell xps m1330 battery for at least 40% – 50% of the electricity I let the self-discharge, if there is no electricity, then let the battery self-discharge, it is easy to problems or even scrapped.

F, Death, but there is no way to pull the battery

The reason is because in the standby state, the memory is powered and working, if the rash direct access to the battery down, data loss is inevitable, but do not get inserted when the AC adapter, batteries, this approach can only be a hundred harm than good.

How to buy a replacement laptop battery

When we plan to buy a NON-OEM laptop battery, or just say replacement battery, first, we have to gather some understanding on laptop battery market. What kind of battery is a replacement laptop battery? (gd761,kd476) How does a replacement battery be produced? Where should we buy it? And what is the normal price? Second, we need to know how to judge the quality of a replacement laptop battery, judge it based on what kind of criteria and parameters? I have searched much battery knowledge regarding how to buy a replacement laptop battery and gathered below information for your review, hope it can give you some help or suggestions.

1. Try to know classifies of laptop battery in the market:

A. Original genuine laptop battery.

It is a kind of battery which the laptop manufacturer and laptop battery manufacturer sign cooperation agreement that the battery can’t be sale at exterior, it only supply to its laptop manufacturer offer to their subject area, which is the exclusive agency that sells at highly price,dell inspiron e1505 battery ,inspiron 1501 battery .

B. Counterfeit Original laptop battery

This kind of battery always been advertised as genuine OEM battery but sell at low price on some online stores. It is make use of some consumers anxious to get the expensive original laptop battery at cheap price. It is mainly made up of dissembled battery cells and the scrap circuit board that wrapped by a new enclosure, stick with original label to fool the consumers.

Notice: This kind of so-called original battery haven’t been undergo the strict security performance test, it is dangerous to use, and the online store holders are some retail individual management has no official after-sale guaranty.

C. Laptop battery be produced by OEM manufacturer

It should be produced by the formal OEM manufacturer, but there are still exists few non-formal OEM manufacturers impose the disordered market to gather in the poor quality dell laptop battery cells and old circuit board, change the enclosure and label the OEM sticker to cheat the consumers.

2. How to judge the quality of a replacement laptop battery?

Replacement laptop battery mainly made up of three parts, battery cell, PCM board, and enclosure. As you know these are the substantial parts directly affect the quality of a laptop battery, let us discuss the notes of how to choose a replacement laptop battery.

A. Replacement laptop battery cells

The quality of the cells decide the capacity, standby time, and using times of a laptop battery–sony vgp-bps2c ,sony vgp-bps2a battery. so we need to see the cells is imported or not, as the import quality is better. Then we need to know its security ability, it must has second protection, because second protection can avoid exploding basically, of course it should be based on the qualified battery cells, if the battery cells have problem, then it is empty even other parts are perfect.

Another thing is that the insulation material in the laptop battery is also critical, as the battery cells are easy to short-circuit if the insulation material has no effect. Therefore, even the battery cells have second protection it is also dangerous, and the insulation material have to resistant high temperature as well, fireproofing is better to avoid damage for the laptop battery.

B. Replacement laptop battery PCM board

PCM board determines the compatibility of a replacement laptop battery. Normally speaking, the replacement laptop battery manufacturer setups the PCM board program follow the original laptop battery manufacturer, this program no need to same as the original laptop battery, but it must match with the original laptop. To compatible with the laptop, it has to be tested by original laptop battery, this procedure will increase the cost of the replacement laptop battery manufacturer. Under the normal condition,sony vgp-bps2c and vgp-bps2a battery , the laptop batteries R&D person can judge the new program can compatible with original laptop or not, so many small scale replacement laptop battery manufacturers omit this test. But not all of the manufacturers omit this procedure, some large scale replacement laptop battery manufacturer in order to responsible for the consumers, they will spare no expense to do this test to achieve the battery compatible with original laptops perfectly.

C. Replacement laptop battery enclosure

It will be better if the enclosure is made from fireproof material, it can resistant high temperature to protect the component in the laptop battery.
