Laptop battery in the end like how the charge is correct, how can we look for laptop batteries charge more lasting, you need to know the correct way to extend your laptop rechargeable sony vgp-bps8a battery,sony vgp-bps9 battery life, but also enables your notebook more secure. That the following are some basic notebook on battery charging basics.

Here are charging the explanation, if you do not want to become professional, you can skip. . .
1. Ni-Cd and Ni-MH battery charging method:
a. Constant current charge: The entire process of charging a certain value of charge current, this method the most common.
b. Constant Charging: Charging at both ends of the process of charging power supply to maintain a constant value, the circuit current as the battery voltage increases and decreases.
c. constant current constant voltage charging: constant current charging the battery first by CC, when the battery voltage increases to a certain value, the voltage remains the same CV, the circuit current is reduced to a very small and eventually tends to 0.
2. Lithium battery charging method: constant current constant voltage charging: constant current charging the sony vgp-bps9/b battery,sony vgp-bps9/s battery first by CC, when the battery voltage increases to a certain value, the voltage remains the same CV, the circuit current is reduced to a very small and eventually tend to 0
 
It talked about activation problems.
Q: bought a new laptop, in the end do not need to activate?
A: need to activate, one or two is enough, preferably more than 10 hours each time;
Q: So, how to properly charge? Some people say that the machine automatically shut down each time you use to recharge better. Some people say do not bother to pay attention to at any time will do.
A: This does not matter, and at any time charge will do.
Q: Many people use an external power supply, in order to save battery wear and tear, all unplug battery. This approach advocates do?
A: Yes, calling for that.
Edit Summary: From the mouth of one dealer, we can see him every time guidance to consumers when they purchase promotion: buy a new laptop computer, to activate the battery; lithium sony vgp-bps9a battery,sony vgp-bps9a/b battery no memory effect, therefore, can be charged; regular external power supply using a laptop, it is best to pull down the battery.
Common battery charging method are there?
Here let us listen to the next one specializes in notebook computer lithium battery engineers answer.
Q: bought a new laptop, in the end do not need to activate?
A: No, because those laptop batteries have been activated at the factory Well, as long as the normal use of the line;
Q: So, how to properly charge? Some people say that the machine automatically shut down each time you use to recharge better. Some people say do not bother to pay attention to at any time will do.
A: at any time will do. Each time you use to recharge the machine automatically shut down better, so take full advantage of each charge and discharge are on the long battery life. Similarly, 500 times, "at any time charge" could put 500 ran out of the year, and "each time you use the machine automatically shut down and then recharged," has only used two or three hundred times, naturally the latter better.
Q: If you charge, charge half to a halt due to power outages. Followed by a full, this is counted once or twice a charge?
A: be counted twice.
Q: Can this be the so-called "memory effect" do?
A: Lithium sony vgp-bps13/s battery,sony vgp-bps10 battery no memory effect.
Q: Many people use an external power supply, in order to save battery wear and tear, all unplug battery. This approach advocates do?
A: Yes, calling for that to avoid the transfer of power from the external to the built-in loss.
Edit Summary: The answer from engineers, we can see that the idea is: buy a new laptop without having a long time to activate the battery; in order to extend laptop battery life, the best every time when a re-charge the battery consumption of finished ; If regular external power supply using a laptop, it is best to take off the battery.
Finally, we interviewed his friend was a "monastic years," the books players in the notebook technology has many unique insights to see how he answers these questions:
Q: We bought a new laptop, in the end do not need to activate?
A: No, because those laptop batteries have been activated at the factory good;
Q: So, how to properly charge? Some people say that the machine automatically shut down each time you use to recharge better. Some people say do not bother to pay attention to at any time will do.
A: no need to go to pay attention to, are generally higher than 100% stopped charging, and less than 95% of them are charging. This technology is not just limited to IBM's battery, because the sinking, power management chip is ALMTL products, and now the sony vgp-bps10a battery,sony vgp-bps10a/b battery manufacturers basically use this program. Of course, some super-cheap laptop batteries, I can not be sure.
Q: If you charge, charge half to a halt due to power outages. Followed by a full, this is counted once or twice a charge?
A: be counted twice.
Q: Many people use an external power supply, in order to save battery wear and tear, all unplug battery. This approach advocates do?
A: no need to remove the battery. Battery Built-in anti-overcharge protection circuit, the battery fully charged in the case, will not have the battery caused by wear and tear; Secondly, remove the battery again if the power outage, would be a bad image notebook itself.
Edit Summary: This is the name players to promote the books: the new notebooks do not have time to buy to activate the battery; in order to extend laptop battery life, the best every time the battery consumption of finished and re-charge; regular external power supply using a laptop, in order to protect notebooks, it is best not to remove the battery.
Sort out the three major controversies laptop battery
   The data on notebook distributors, laptop sony vgp-bps10b battery,sony vgp-bps11 battery engineers and books in the words of players, you must know how to deal with their own battery of books. According to the information that the new battery to activate the work have been completed at the factory, the new notebook's battery power with a little natural wear and tear in order to avoid the harm to the battery, do not have to listen to those dealers call "to pass 10 hours or more time to activate "or similar argument.
   Notebook computer lithium-ion battery life is limited, generally 300 to 500 times after repeated charge, they can not be recharged inside the. Consequently, according to the information we are currently in the hands can be seen, in order to maintain the battery's "maximum life", or try to run out of electric re-charge. However, Xiao Bian would like to remind you that we buy laptops is to use is to allow it to become their own work, study arms, the day care to care to go this way, do you too much trouble?
   For the third debate, our view is: Use an external power supply, do not unplug the battery. From the perspective of lithium batteries, as rechargeable lithium sony vgp-bpl11 battery,sony vgp-bps13 battery have a certain number of limitations, and therefore it taken down from the laptop, or can be extended more battery life. But this approach to the notebook computer itself is very dangerous, if a sudden power outages, due to currents and other factors impact on the notebook itself. As some of the big names in this area was pretty good considering, such as the ThinkPad, it is a special built-in battery protection technology, only battery power less than 95% of the time carry out the charge.
  Here, readers can usually add the proposed purchase of a spare battery, usually on the notebook in general, to prevent blackouts and other bad situation, after all, books are burned because of power outages to the data there are also many of the destroyed. Out of the house can be bought for. This is the best.
  Is not recommended go to the store to buy a lot of help major brands sony vgp-bps13/b battery,sony vgp-bps13a/b battery,sony vgp-bps13b/b battery manufacturer has its own website, where you can buy cheaper than half may be even more the quality is guaranteed.

According to the report of the battery industry statistics show that China's battery industry is facing severe challenges, resulting in industry-wide economic decline in profitability of battery manufacturers are suffering a huge impact on loss-making enterprises to expand, some business failures are converted, the two main reasons:

1, battery materials prices continued to rise

China's battery industry is currently facing a serious problem of "internal and external" troubled. As countries around the world to improve environmental protection requirements, and some developed countries have stopped the lead, cadmium, nickel and other nonferrous metal production in the country in order to pass on its own environment pollution; This resulted in electrolytic lead prices soared, from 2003 to 4,500 yuan per ton rose to 13,000 yuan per ton early this year; nickel price from 150,000 yuan per ton last year or so, now risen to nearly 450 thousand yuan per ton. In addition, raw materials,compaq laptop battery,compaq evo n400c battery cobalt, cadmium, natural manganese powder, zinc and other prices are soaring to varying degrees. As the price of export products is well established with the signing of the contract, raw material prices, the price can not sync to follow, resulting in a "export more, the greater the loss" situation. Of domestic battery production coupled with fierce competition among enterprises, leading to their accumulation in recent years, the low rate of weak to resist risks; of these factors are intertwined with each other a direct result of domestic battery producers are moving forward with difficulty and had to have reduced the scale of production and marketing in order to reduce the loss of .

Second, the export tax rebate policy adjustment on the battery industry, the impact of

September 14, 2006, the State Ministry of Finance jointly issued by five ministries and the "some of the goods on the adjustment of export tax rebate rate and the addition of the processing trade ban catalog notice." According to "Notice" provisions of lead-acid compaq evo n410c battery,compaq evo n400 battery, mercury oxide battery export tax rebate policy has been canceled; As early as in 2004, the battery began to export tax rebate rate down year by year, and will be progressively removed in rebate. The current lead-acid batteries, mercury oxide, and nickel-cadmium batteries have been included in the prohibited category in processing trade directory, for inclusion in this directory should be levied on imports of goods, import duties and import taxes.

According to agency statistics, the export tax rebate rate down 1 percentage point each, equivalent to the cost of exports in general trade increased by about 1 percentage point; So the introduction of export tax rebate policy would reduce the competitiveness of the battery export market, which will speed up the battery industry to re-wash Brand, a number of competitive small and medium enterprises will be a serious loss, or even face closure.

Third, the green barriers abroad, the impact of China's battery industry

According to the EU "Official Gazette" The recent enactment of compaq evo n410 battery,compaq evo n600 battery and battery instruction, for the battery in the lead, cadmium, mercury made more stringent target, and involves the commitment to the expensive recovery costs. REACH regulations and directives based on RoSH improve battery registration fees and testing fees, substantially increased the cost of battery production and export cost of sales.

European Union and other developed countries frequently set the "green barriers", have resulted in a substantial increase in the cost of exports of batteries, some SMEs have to because of economic reasons and technical reasons to give up overseas markets.

Fourth, foreign anti-dumping and technical barriers to the impact of China's battery industry

China's battery industry after another 337 hit the U.S. case of alkaline manganese batteries investigation, the United States investigating the case of 337 lead-acid compaq evo n600c battery,compaq evo n610c battery, the United States corporate charge Ni-MH battery Chinese company royalties, the United States and Japan, the case of lithium-ion batteries and other intellectual property rights patent cases, in order to the respondent, consumption of used a large number of Chinese enterprises involved in the human, material and financial resources, the sales network has been badly hit.

Recently, China's battery industry is also hit South Korea alkaline manganese batteries of anti-dumping sunset review, India, dry batteries of anti-dumping sunset review. Has gone through the lead-acid batteries and other products for more than a dozen anti-dumping, the battery's export trade was severely affected.

Some anti-dumping cases and 337 enterprises involved in the investigation because they do not respond, which led to the prosecution the entire industry out of the local area market.

Responding to the lack of funding mechanisms in the current circumstances, the enterprises under immense pressure.

5,the RMB appreciation on the compaq evo n620c battery,compaq presario 2100 battery industry, the impact of

The RMB exchange rate from 2005 1:8.3, adjusting the current of about 1:7.5. China's battery production in about 80% of exports, the yuan appreciation, while the export price of the battery difficult to raise the cost of exports is markedly improved the battery to enable enterprises to economic decline.

6, transport costs

With the energy crisis, the battery transportation costs increase. In many parts of the Ministry of Communications goalkeeper lead-acid batteries and nickel-cadmium batteries as dangerous goods transport, and forced recruitment costs, increase the burden on businesses and affect economic efficiency.

7, the compaq presario 2500 battery,compaq presario r3000 battery industry, the situation serious occupational hazard, environmental protection and management of investment to improve

Lead-acid batteries and nickel-cadmium alkaline battery positive and negative main raw materials are lead, cadmium, nickel and other non-ferrous heavy metal compounds, especially metal ions cadmium and their toxicity and poisoning have a strong role in the manufacturing process stirring up the dust, the resulting waste water and waste, pollution, through a variety of ways by the human body after intake will continue to deposition, play a role, eventually leading to poisoning of the bone loose, hematopoietic function and kidney damage. Battery contaminated soil or water, and again by the growth of plants, vegetables and invades the human body for in-depth infringement.

To sum up, China's battery enterprises are facing difficulties, enterprises should strengthen technical, process and equipment innovations, improve the utilization of raw materials and improve resource utilization, reduce as much as possible due to rising raw material adverse effect ; actively improve the production process, speed up the pace of eliminating backward production capacity as soon as possible transition to the production of efficient, environmentally friendly and energy-saving compaq presario v4000 battery,compaq presario v5000 battery direction to promote the sustainable development of the battery industry.

According to foreign reports, the Chinese carmaker BYD Auto, said BYD to sell electric vehicle batteries are the same European and American car manufacturers to start negotiations.

BYD said in an interview CEO Wang Chuanfu BYD is working with an American and two European car manufacturers to sell lithium-ion batteries to negotiate, but Wang Chuanfu and BYD other management personnel refused to disclose the details of the manufacturer.

Wang Chuanfu indicated that they might sell to Europe and the United States toshiba pa3191u-4brs battery manufacturers have been in the F3 BYD dual-mode electric vehicle use. F3 dual-mode electric vehicles in China in December last year, an official for the corporate clients sales, despite limited, but the car belongs to the pioneers in the segment of the market than Toyota Motor Corporation plans to release later this year, a similar model time to market ahead of a year.

BYD's toshiba pa3284u-1brs battery technology and the leading U.S. battery suppliers A123 Systems, Inc. (A123 Systems) technology in a design similar to, if the car manufacturer BYD to reach an agreement with Europe and the United States, BYD will be A123 Systems, Inc. competitors. A123 Systems Inc. executives declined comment.

Wang Chuanfu said that, compared to foreign competitors, BYD has the advantage of a low battery production costs. Last year, Warren Buffett's MidAmerican Energy Holdings Company was BYD stake to 230 million U.S. dollars, mainly because of promising low-cost toshiba pa3285u-1brs battery BYD production technology.

The face of the increasingly serious energy situation and environmental situation, the world's car manufacturers start to the commercialization of electric cars and hybrid race. The material is cars with lithium-ion power toshiba pa3285u-2brs battery the mainstream of development direction, but because of its relatively high price, cycle time is not long life and unstable explosive issues such as the applications subject to certain restrictions. But Wang Chuanfu said BYD's lithium batteries used in the chemical characteristics of a stable iron phosphate technology, security has been ensured, while costs are well controlled.

At present, BYD in the global electric vehicle market has a certain degree of brand recognition, BYD in the December 2008 Detroit auto show display plug-in hybrids so shocked the automotive world. If the car manufacturer BYD, and Europe and the United States to successfully reach an toshiba pa3285u-3brs battery,toshiba pa3331u-1brs battery,toshiba pa3356u-1brs battery agreement will further enhance the BYD in electric vehicle market reputation.

Recently, Swedish scientists have used cellulose produced by algae, like paper-thin, lightweight, flexible battery can be used to track products from the origin to the shelf's whereabouts, or used to track baggage through the airport security whereabouts. Related research published in the latest issue of "Nano Letters" on.


Electrochemical reaction on the work of the dell inspiron 9300 battery, each cell contains two electrodes (cathode and anode), the two electrodes immersed in electrolyte. Now widely used in mobile phones and laptop computers in the lithium battery anode from the carbon composition of lithium cobalt oxide cathode by the constitution, dissolved organic lithium salt containing electrolyte. When the battery is when you pass on the power electronic North Korea embarked on the cathode, forcing positively charged lithium-ion away from the cathode into the anode, when the battery discharge, the current from the anode for lithium-ion to return to the cathode.


Albert Te Milan Uppsala University in Sweden and his colleagues invented a result of the battery from the seaweed extract made from the cellulose (paper is extracted from trees or cotton, made from cellulose). Algae cellulose fiber is more slender, make a larger surface area of the dell inspiron 9400 battery so that it can store more charge.


However, the fiber itself is not conductive, Milan because of the team using a common conductive polymer polypyrrole (polypyrrole) to surround fiber. Polypyrrole is usually amorphous black solid, insoluble does not melt at 200 ℃ when the decomposition can be conductive. The researchers report their submerged algae fibers, resulting in a mixture can be conductive. Then, they are in such compounds in the manufacture of a new dell inspiron b120 battery poles, using filter paper soaked in salt water as electrolyte.


The new cell consists of two cellulose electrodes and caught in the salt-impregnated filter paper composition, looks like a sandwich, two cellulose electrodes located in between two glass slides. Poles attached to the platinum with the formation of conductive contact with the outside world. In the polypyrrole chemical changes occurred in storage and release of power, in which the molecules dell inspiron b130 battery exist in two forms, that is the term called "oxidation state" and "restore state", when these two states of the molecules to form loops, that is to generate electricity. The battery can be charged within a few seconds, but after 100 charge-discharge performance does not appear large losses.


Dr. Milan are due to find a business for this scientific and technological achievements "mother." At present, the efficiency of algal cells is only one-third of lithium-ion dell inspiron e1405 battery,dell inspiron e1505 battery which although not a substitute for lithium batteries, but there are also a unique display their abilities, can be used with a small radio devices, luggage tags, using the signal to Luggage regulators to track the location of baggage; also be used for "smart" packaging materials, such as with electronic display box. In addition, Dr. Milan battery can also be due to the recent successful development of the transistor components of paper-based charge.
