Chemical Battery

Laptop No Comments »
Chemical batteries, is across the electrochemical reaction, the positive, the negative electrode material of the active chemical energy into electrical energy a device class. After long-term research, development, ushered in a wide variety of chemical batteries, widely used in the situation. Great as a building can accommodate a lot of great invention, small enough to count the species in millimeters. All the time is not a better life for our service. The development of modern electronic technology, chemical batteries made very high demands. Each chemical battery technology breakthroughs have enabled a revolutionary electronic device. Modern society, people, daily life, more and more inseparable from the chemistry of the battery. Today, scientists are focusing their electrochemical interest as a chemical battery powered electric car niche.

Dry and liquid battery

The distinction between liquid and dry cells is limited to the period of early cell development. The first battery of glass container filled with electrolyte and two electrodes. Has been launched to paste electrolytes based batteries, also known as dry cells.

There are still “liquid” batteries. The size is usually a very large variety. Such as those used as a source of uninterruptible power supply in large stationary lead-acid batteries or solar cells in supporting the use of lead acid batteries. For mobile devices, some using a full-sealed, maintenance-free lead-acid batteries, these batteries have been used successfully for many years in which the sulfuric acid electrolyte is determined by the silica gel or fiber glass suction separator pay.

Disposable batteries and rechargeable batteries

Disposable batteries commonly called “disposable” batteries, because their power runs out, you can not recharge using only discarded. Common disposable batteries, including alkaline manganese batteries, zinc-manganese batteries, lithium batteries, zinc, zinc-air, zinc-mercury batteries, mercury batteries, battery, and hydroxide magnesium, manganese batteries.

Rechargeable battery according to materials and production processes on the different currents are lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-hydride batteries, metal, lithium-ion battery. The advantage is a long life cycle, which may be more than 200 full charge and discharge, and some rechargeable batteries power the load higher than most disposable batteries. Ordinary Ni-Cd, Ni-MH battery, the memory effect only, causing inconvenience to use, often cause early failure.

Theory of battery time

The theory of the charging time of battery: battery charger power divided by the output current.

For example, a 800mAh battery, for example, the charger output current 500MA load when the time is equivalent to 800MAH/500MA = 1.6 hours, while the charger shows charging is completed, preferably about half an hour or and should be given to supplement the battery power up time.

Fuel Cell

Fuel cells is the chemical energy of fuel through an electrochemical reaction into electrical energy directly to the camera is using batteries to hydrogen fuel at the anode is produced by oxidation of hydrogen oxidation hydrogen ions, whereas the reduction reaction of oxygen carried to the cathode, and Coming of the anode generates hydrogen ions with water. Oxidation process-reduction reaction can generate electricity. Fuel cell technology, including the existence, in the alkaline fuel cell (AFC), the fuel cell Phosphoric Acid (PAFC) cell proton exchange membrane fuel (PEMFC) fuel cell molten carbonate (MCFC), solid oxide fuel cell (SOFC) and Fuel Cell Direct Methanol (DMFC), etc., whose use of the oxidation of methanol as a positive response to the cell technology fuel, but he is optimistic about the industry and positive developments.

charging after run out of battery can extend the battery’s life

Laptop No Comments »
In lady security company advertising these days use mobile battery is very concerned about fat. She told reporters that his company advertising and telephone number of every day, but she bought a cell phone before the battery is not sustainable to use for a year, and now the battery can be used that ‘one day. Reporters ask how to use the battery of Samsung Service Center Miss Zhao, Ms. Zhao said the use of mobile phones should pay attention to:

      Zhao, new phone purchased, the first mobile phone charging time should be longer. Phone purchased on the market in general on the battery is full power (currently the majority of mobile phone battery was activated before use), so customers after the purchase and then charge the battery is first usually the first charge time should be longer, but different brand of mobile phone battery charging time to first use the length and frequency are not the same, the customer must conform strictly the instructions. Such as Samsung, the battery runs for the first time, the price of only 4 to 6 hours, then perhaps, but some brands for the first time required to charge 6 to 8 hours, or even three times in front of a certain time must be sufficiently specific circumstances and needs vary airport in. Currently, the market capacity of mobile phone batteries, 600 mA, 800 mA, 1200 milliamps, etc. In short, the higher the number, the more Long battery mode, but the relatively long duration of load will be more.

      Secondly, the mobile phone battery is preferable to use the full power of not being able after reloading, so as to extend mobile phone battery life. On Miss due to busy every day with two of the battery is fully charged, and sometimes there are one or two batteries of cell phones do not work out, she went to charge. Samsung customer service for Ms. Zhao said, time is not desirable. The lifetime of the mobile phone battery and battery charger has a significant relationship between the number of times, pricing and the higher the number the higher the amount of wear on the battery. On Miss if the battery runs out after charging the battery of his mobile phone a lot of positive and sustainable results.

      Never interrupt the loading process. We used some bad habits: for example, the process of charging the unplug the charger to see what temperature the battery, then reconnect the charger or a temporary emergency, unplug the phone to talk about phone. This will normally lead to instability in the charge cycle, the battery to restart a charge cycle is complete, but before the charging cycle is complete and this charge will reduce the life cycle of the battery of instability.

Laptop battery life

Laptop No Comments »
Lithium-life laptop battery ion is limited, typically 300 to 500 times after repeated loading, they can not be reloaded into the file. Therefore, according to information we are currently in the hands can be seen, to keep the battery “life to the fullest,” or try to run out of power again.
Use an external power supply, do not disconnect the battery. From the perspective of lithium batteries, as rechargeable lithium batteries have a number of limitations, so he got out of the laptop, or can be worn over battery life. But this approach to the laptop itself is very dangerous if a sudden power outage, due to currents and other factors have an impact on the notebook itself. As some of the big names in this field was very good considering, as the ThinkPad is a special built-in technology to protect the battery, only less than 95% of the battery to recharge when it is ibm thinkpad r50 battery

Battery cells and rechargeable batteries, the difference between the ordinary

Laptop No Comments »
1. If you buy a replaceable battery, is not as long as the voltage is the same as you can. For what brand and power requirements must also be the same? There are changed, the laptop battery from the circuit at the end, will not affect the recognition?

  
  

A: The device is a single 18,650 battery voltage lithium 3.7 volts, so the interior must be loaded into the series of notebooks and parallel combinations to get the laptop to the required voltage and capacity. Under normal circumstances, after the circuit can be solved by fleas brush circuit does not recognize the issue of battery.

  
  

 

  
  

2. If you can not buy batteries, then the market can be used on the 5th player rechargeable batteries? What will be bad consequences. Is it too can be as long as the voltage is the same?

  
  

A: First, I doubt not, on voltages, so it certainly can not be replaced, now available in the market on the 5th battery, mostly nickel-hydrogen batteries, is not common, the consequences are very serious, another notebook adapter to charge the battery explosion.
 
3. Different types of batteries may be interchangeable? I mean, lithium-ion, batteries nickel hydrogen and nickel-cadmium batteries in between. How do batteries last? Ordinary rechargeable batteries, so what?

  
  

A: Different types of batteries are not interchangeable, because the operating voltage of different batteries have different voltages can withstand

The battery industry is with the wind drift

This year, with the introduction of a new energy policy and the Government of solar energy, change-intensive approach: from a “positive focus” on the importance of “strategic” than the A-share market is pure concept solar stock, expand the New Energy (02218. SZ) shares less than 11 yuan for the year increased by 34 or so along the road, or up to 200 %.

The new revenue expansion can come from three main businesses in 2008, the company recorded total operating profit of 290 million yuan, net profit of 73 million euros, the product mainly for the overseas market sea, the proportion of exports to reach 90%. Among them, civil solar cell products, which represents 40% of main income; chips amorphous silicon solar cells and components accounted for 31% of the chips of crystalline silicon solar cells and components accounted for 29%. The company achieved sales of amorphous silicon solar 13mW, sales of crystalline silicon solar 5 MW. Companies over the last three years average sales growth of 30%, with an average rate of return of 24%, overall activity, the average gross margin of 36%.

The current products as solar cells stable crystalline silicon solar cell, conversion efficiency, in future, the market will continue to occupy a dominant position. However, solar cells crystalline silicon due to a more mature product, the gross margin is not high, large-scale international companies also generally maintained at 17% ~ 20%.

Amorphous silicon thin-film batteries with low costs, high margins (50%) and good potential for development is to become manufacturers current national and international solar energy for the new domain. In 2008, Rio Cell New amorphous silicon solar can be taken into account for the turnover ratio of 31.28%, gross margin reached 47.39%.

Although the conversion efficiency is low compared to solar cells crystalline silicon there is a large gap, however, given the crystalline silicon industry, intense competition, excessive reliance on silicon raw materials, and high cost of current international manufacturers and domestic solar began participating in the a-Si solar cell field.

As a second generation of the representation of a thin film amorphous silicon solar cell business by expanding into the new technology of solar cells in amorphous silicon and equipment has an independent research project remains strong and strengths development, and clients are primarily long-term customers, relatively stable and not now - crystalline silicon solar cell production and export volume ranks consecutive year, China first. If production line as the company more than 70% of their own R & D, manufacturing facilities, dependence on imported production equipment from other similar companies, the company significantly reduces the cost of the margin Gross product is much higher than the industry average.

However, the financial crisis, in October last year, the PV industry in product prices and demand faced by dual-drop this year, one quarter of poor results, net income fell 36%, the second quarter, although improved, but
In the short term, foreign demand remained sluggish, the industry is still no significant improvement in the plight of the products exported to over 90% of the extension is still optimistic about the New Business Performance.

While construction companies Leshan industrial park and new production lines will reach full capacity, the company will increase production of dual-battery business, performance will be significantly increased. However, in industry, attracted by high margins and other solar companies are springing up like a production plan can only lead to future competition in the field of solar cells in amorphous silicon increased the level of margins decline risks.

Contrast Apart listed companies in the battery industry, as the first purely domestic firms listed photovoltaic cells, the cells multiply the new silicon may be amorphous solar in China is currently the largest production and sales, competitive advantages are obvious, results in strong growth, with a value of more good investment. Taking into account the valuation levels of international manufacturers of photovoltaic cells, or about 50 times earnings, and A-share market valuation of solar companies is much higher than the international market, the company expects EPS for 2009 approximately 0.45, consistent with the assessment given at 80 times PE and reasonable price for the 32 ~ 40.

In Europe and the United States, given the grim economic situation, there are some risks, we recommend investors to be cautious outlook in the short term investment.

Celestial Dealers: Financial crisis sales increased rather than decreased

Laptop No Comments »
August 22, 2009 Celestial cup brand battery new money in place Resorts Qingyuan, followed by provincial officials across the country have expressed their “celestial sphere battery sales environment of the financial crisis has not affected, but to achieve growth Fast. This encouraging situation occurs because the business heaven implement brand strategy, ahead in marketing concepts and models, the system of product development have achieved success. ”
Liaoning, Shenyang, said Zhou, the celestial sphere in marketing Northeast, sales of batteries for one year a higher level, but in 2008 as sales of the battery the celestial sphere has increased more rapidly than ever before. Shijiazhuang, Hebei Mr.Yan began in 2008 and companies celestial sphere, while also operated Nanfu, deer and other brands. However, Mr Yan said that the financial crisis, although the impact of the mainland market is not great, some batteries or a decrease in sales of the brand, but marks his agent sold Celestial on the market in Hebei are improved significantly. There Sichuan Chang, Guangzhou, Mr. Liang and other provincial agencies across the country say they are agents of the market, sales of battery celestial sphere in 2008, and the first half of 2009 compared to sales of both substantial growth.

Why Celestial batteries in the financial crisis, not only was not affected, but a substantial volume growth? Agents participating in the quasi-unanimity that the celestial sphere to emphasize the marketing strategy of the brand and market oriented research in a variety of products to enhance the scientific and technological innovation, further specialization, to ensure Many of the domestic market, while the financial crisis in 2008, few signs of when companies assess the situation and take timely and effective measures, such as depth distribution, etc., maintenance and development market has played an influential role in 2008 at the end of network marketing to promote the “Liao Shen Evening News” to promote the news brought her many customers and real sales.
Ms Zhou said that even if its market in the northeast, away from Guangzhou, but the celestial sphere of its marketing company to help large, so in cooperation with the celestial sphere of those years, year after year, its high turnover; Mr.Yan am happy to say that the celestial sphere of the company brand marketing strategy for his great help, for example, in 2009, the China Central Television on the celestial sphere ads Battery He also monitored the sales. There’s last year introduced the depth distribution, allowing the development of access to secondary and tertiary market for many marketing assistance, custom mode for market development this year Hebei series very able batteries for the province of Hebei, which should open the market exploits of famous military Sichuan, Mr. Chang that diversification produces heavenly society of great help to him, because the product some wholesalers to complete one-stop shopping, competitive advantage on the account. Mr. Zhang would like to seize business opportunities in Sichuan, and quickly occupied the market, so the exchange of the General Assembly, he was greedy and Celestial distribution companies in depth to discuss leadership issues , hoping to send the celestial sphere, “coach” the team’s marketing team in the celestial sphere of operations model, the development of the company’s momentum. Guangzhou, Mr Leung that the celestial sphere in recent years a great effort to promote the brand, but also paid close attention to how to foster innovation in the battery industry are very strong, and the results are obvious.

Celestial Industrial Co., Ltd. Guangzhou, Deng Hua, director of marketing presentations, heavenly batteries have always been very sharp on brand promotion, from 2006 on an annual basis to advertise on television station as well, but also in major media across the country to three-dimensional extension type, even when the battery through the celestial sphere Mitsubishi of Japan and the battery and the joint development of Guangdong University of Technology, product quality and technology was the development by leaps, so strong media awareness, acceptance of the product to the consumer more and more, which Dealer is extremely important, according to the characteristics of the farm product, the focus of the Research company on new products, so that a range of products to meet the needs of different consumer groups, the Celestial battery current has reached more than 200 kinds of species, another has developed a new series of The Cup -battery technology on the market for the future of the leap forward development has laid the groundwork in order to cope with the financial crisis, turn to join since last year, the company on a strategy bold and innovative marketing to adopt various means to implement the marketing strategy to help provincial governments Agents seize the financial crisis in other battery brands declining market opportunities, quickly open new markets to increase the share of battery market celestial sphere to distributors as partners, distributors and companies celestial achieve common development.

Buy Laptop and Battery from a Reputable Website

Laptop No Comments »

When we are ready to spend our hard earned money, we want to always make sure that we visit a reputable online store that will deliver the best possible quality and won’t just keep our money and deliver low quality products. However, it’s not always easy to merely browse a web site and then determine whether we have found just the perfect web site for shopping or not. Evaluating a site and determining its authenticity requires many things. We need to see whether the web site has certain traits or not. If it does, we should go ahead and order products from them.

When you are ready to buy your hp pavilion dv8000 battery or hp pavilion dv9000 battery  online, one of the most important things you should look for on a web site is if they offer money back guarantee or not. There are literally countless web sites selling computer software and hardware and since there are black sheep every where, there might be some web sites that won’t care about delivering quality products at all. So, having a money back guarantee will show that they take their business seriously and they do care about their customers.

Take a look at it in this manner: If you sell something online and you are offering a money back guarantee, won’t you offer quality products to avoid refunds? If you won’t deliver quality products, you will lose in many ways. Meaning, you will have to refund the money, you will have to get the product packed again, etc. So, to avoid all this hassle you will most certainly deliver quality products.

This is why money back guarantee is very important online. It serves as a security measure that the web site you intend to purchase your printer cartridges from will send out high quality toner cartridges to their customers, always.

Also, check and see if they have any restrictions with the money back guarantee. Ideally, there shouldn’t be any conditions at all. If a web site offers a 100% risk free money back guarantee, then it will show that they have faith in the quality of their products. If you think they are playing games and have not explained their money back guarantee in simple words, you may want to avoid buying your toner cartridges from them.

So, always look for a money back guarantee when you buy laptop battery  online to ensure that you will receive high quality toners that will last long and will give you professional quality print results.

IBM laptop battery repair combat

Laptop No Comments »

My IBM2611 laptop, spent more than three years, and the battery has not been looking the other. The last six months, the ability to supply energy to the battery deteriorates, watches today for a test, actually use just 20 minutes. Originally wanted to purchase blocks of new troubles, never thought to inquire about a blue accessories Monopoly Express, I would like: Battery lithium-R2611 850! My machine is that now the value of money? To put an aftermarket battery sold 350, said Paul month, but a month later?

There is no way the reader access to the chat bar Qiujiao web master. In various forums laptop or a Web site, anywhere on the old battery cores for the introduction, there are specialized to make the live dealers. A battery of 10 to 25 months. However, since I use the battery from IBM, there are eight nickel-hydride batteries, metal, calculate required at least 100 bar yuan. Although the 100 is a side dish, made after the event No, not even 20 minutes of the original disappeared. Can not take the risk.

      At that time, the Forum has a master above me in my mind: Ni-MH battery memory efficiency is very obvious, perhaps you should first try to discharge, and then decide what to do. I sent for multimeter, battery measurement in 2611 is negative, the battery of both ends of the interface is positive and negative. An amount of voltage is 10V, the voltage seems normal, completely discharged, the battery is still great potential responses.

Now, on the implementation of the landfill. Disconnect the AC charger, start the computer to see if the display power: 98%, open Winamp to play MP3 files, listening to 20 minutes, the computer prompts the preservation work. Showing 1% of electricity right now. The computer hibernates in soon. Stop, remove the battery, a voltage test, strange 10V! If he found two small 6V emergency bulb connected to a power supply, unusual light bulb, then such a bar to lie, after nearly two hours, the lights finally went out (and later found burnt out). The battery is installed, connected to the mains, boot, power management, the display is over, about 5 minutes, even charge 60%! How is this possible? ? ? Almost a half-hour of electricity filled. Start “Battery

Bar tests that showed that 100% of electricity, unplug the AC charger, battery

Bar shows 98% battery remaining, estimated time of 3 hours 10 minutes. Feel happy, but my heart: “Is this the list? Too easy a bar! “Start Winamp songs, but you have not seen the 10 minutes we heard the alarm sound!” Shortage of electricity, please change the battery. ” Capacity is displayed as 3%, then the computer goes into sleep mode. The battery took only 10 minutes, remove the battery, a voltage or 10 V, seems to release any means, connected to the bulb slowly wait. 5 minutes or so, the lights go out, a test voltage is still 10V. How Gaode, release to let go, it seems that unless you can not see the light bulbs burned! This seems not acceptable.

I installed the battery, disconnect the AC power, start the computer, you can even start! Consumption is still 3%. Then the sound of the alarm quickly, the computer in sleep. Now, I fell into meditation.

Since the battery is still able to boot the computer power is sufficient to show up. Shortly after launch, in sleep, the battery discharge is not stable, no power has been exhausted. So sure the remaining power is enough to start the computer. Better yet, try this: the computer to sleep, click the mouse to turn in a moment like a computer during sleep to activate it again, so that the effective discharge may be a little better. In this way the computer to sleep once every three minutes, time of day. Stir for 45 minutes, the computer may not be the last wake. Remove the battery, this voltage is below 5V, drawing a line on a 6V bulbs, to continue to discharge until the lights off, it must be said that the discharge of success.

Re-install the battery, connect AC, startup. Power Management Display: is in charge of electricity 1%.

I open the Word to prepare to write this article, noted that the display of the battery is still at 1%, but felt the position of the battery a little heat, it should be supported. Waited for 1 hour and 50 minutes, the display power of 43%. I really can not go on and so first test to say.

Disconnect the AC charger, start “Maximize Battery Wizard” to set the battery energy savings average (CPU Speed: CPU speed to medium Medium LCD

The most brilliant display brightness EVEL 7), have begun to measure the battery life, the program runs in the background Winamp, Word. The CPU usage to 100%.

Power output relatively stable, just started from 43% to 37% of the time by two points from 37% to 31% long term and 9 points from 31% to 25% of the time and 9 points from 25% to 3% of the time 10 minutes. The actual use of the battery 30 minutes, consuming electricity of 40%. If the proration of the fully charged battery must be able to use 80 minutes. At this point the battery has declared a perfect return.

Such a result is indeed so I was surprised, not expecting such a way to actually be able to approximate the original is to my old batteries glow a second spring, which is also a sense illustrates the quality of laptop batteries IBM. If you and I have the same scourge of books users can try IBM .

Several major errors of Laptop battery maintenance

Laptop No Comments »

1, for the first time the use of batteries, the first three to be recharged for 12 hours?
    This is totally unnecessary. Because laptops have improved the channels of power management and charging management system, when the battery reaches saturation, the control circuit will automatically switch to the state of the circuit as a full online and not to say that the more you charge can be used any longer.
2, to avoid the memory effect, we should be exhausted before the electric charge do?
    Each charge before the pairs of battery discharge is not necessary, but also harmful. Because it has been proven: the depth of discharge of the battery will not be necessary to shorten the battery life, it is recommended to use about 10% when the battery can be recharged when the. Of course, when the battery is still over 30% of the time advisable not to pay, because the memory effect exists. 

3, insert the area where the battery must win in order to prevent repeated charge-discharge do?
    I’ll give you suggestion is: No! Of course, you can take the natural discharge lithium-ion batteries to refute me by saying that the natural discharges of the battery after access to food appears if there is repeated charge and discharge and shorten of battery life. And I give you “instead of” This is the answer for several reasons:
a. Now, laptops are designed for control circuit power of this feature: it is when the battery reaches 90% (like most HP models), or 95% would, but to achieve this objective by the ability of ‘natural evacuation of one-time 2 weeks to months, when the battery dormant for about a month for a full charge and discharge to maintain the battery capacity, this time you should worry about is the battery should be exercising their body rather than doing nothing again after recharging.
b. Even if the battery has “unfortunately” Re was charged, bringing the loss, not a long time do not drop the battery caused much greater.
c. Your data that you or even your laptop batteries are much more valuable to a sudden power failure will not only damage your laptop and can not restore the data is too late to repent.

4, the long-term preservation needs of the battery is fully charged to do?
    See the table below is obvious: (percentage of saturation when the relative percentage of baseline)
    Storage Temperature 40% state of charge of 100% state of charge
    0 degree 98% (one year later) 94% (one year later)
25 degrees 96% (one year later) 80% (one year later)
40 degrees 85% (one year later) 65% (one year later)
60 degrees to 75% (one year later) 60% (3 months later)
Obviously, if you want long-term preservation batteries as much as possible on the environment and dry at low temperature and allow the remaining capacity of the battery in 40% of the best. Of course, the best to take the battery every month for use once, both to ensure the battery a good state of preservation, but also the loss of damage to dispose of the battery completely.
5, how to use the laptop as far as possible to extend the use of time?
a. The screen brightness to reduce. However, power-hungry brightness of the LCD screen can actually be extended to reduce the use of time.
b. Open SpeedStep and PowerPlay power-saving features such as. Now the laptop processors and graphics chips have a lower operating frequency and voltage to extend the use time functions, open the appropriate option can significantly extend battery life.
c. The use of hard disks and CD-ROM of the spin-down software: Nero as DriveSpeed, PowerBoost can reduce software such as CD-ROM, hard disk speed, etc. can also be effective in reducing consumption of portable power.
d. Make good use of standby, sleep and other functions. As a long time without a computer, allowing laptop to sleep or hibernate, saving electricity extended the life of the computer. 
6, finally:
Of course, the above five aspects of the user is often encountered and general users to compare the problems of confusion. For maintenance of the laptop battery in this topic, I think that as you use, you will find more problems, but also with the continuing development of portable computers, maybe now you find the problem in computers Portable future, maybe we will no longer be a problem.
