Laptop Batteries - How does a Laptop Battery work?

Just like their AA, AAA, and C cell cousins, laptop batteries create an electrochemical reaction that forces a stream of electrons from one place to another. And just like household batteries, laptop batteries have a positive and negative terminal where electrons are received and sent, respectively.
Laptop batteries, however, have unique characteristics compared to household batteries

1. They are rechargeable
2. The laptop battery is composed of multiple internal cells
3. They contain a small printed circuit board
4. Their overall shape of a laptop battery and the location of their terminals vary from model to model

Rechargeable batteries are significantly more complicated to design than a non-rechargeable battery because the electrochemical reaction that provides power must be reversible. As Lawrence Berkeley Lab's staff scientist Frank McLarnon explained to Scientific American.com:

"When a battery is discharged, an electrochemical oxidation reaction proceeds at the negative electrode, and an electrochemical reduction reaction occurs at the positive electrode. When one attempts to recharge a battery by reversing the direction of electric current flow, the opposite takes place: a reduction reaction proceeds at the negative electrode, and an oxidation reaction takes place at the positive electrode.

"In the case of the rechargeable battery, the electrochemical oxidation-reduction reactions are reversible at both electrodes?In the case of the non-rechargeable battery, when one attempts to recharge the battery by reversing the direction of electron current flow, at least one of the electrochemical oxidation-reduction reactions is not reversible. When the battery is charged, the overall reduction reaction that proceeds at the negative electrode may not be the true reverse of the oxidation reaction that proceeded when the battery was discharged.

If the laptop battery process isn't exact, then unwanted build up can take place on either terminal over time, which can cause a dangerous short-circuit.

Also unlike a household battery, laptop batteries are composed of multiple internal cells. These cells are arranged in series and in parallel in such a way that the laptop battery has a higher voltage level than the individual cells. Laptop batteries also contain a small circuit board that controls the way the cells are recharged. Without this board, the laptop battery would not function properly.

Of course, the most obvious difference about laptop batteries is that their physical shape is different from the traditional cylindrical form of a AA, AAA or C battery. Laptop manufacturers custom design their laptop battery packs to conform with the overall functionality of the laptop model. Some laptops and their laptop batteries are engineered for their light weight and small size, others for their ability to replace the functionality of a desktop system. As a result, one size can't fit all in the world of laptop computers. This causes laptop batteries to vary across different models.

The world's largest solar energy company(USA) fought in China

The world's largest solar cell production in the U.S. manufacturer First Solar Inc. (FirstSolar, Nasdaq: FSLR) CEO Bo Song Si In an interview with the China Securities newspaper interview that the PV market is currently facing many uncertainties, but the world right Energy.The demand is still strong growth. Despite the uncertainty in some sectors other circumstances would be a slowdown or a recession, the country for more clean energy and economic programs, strong demand and therefore optimistic about the prospects for the industry.

Germany announced that it recently cut subsidies for solar power industry on the PV market led to concerns about the future, but the Song Bo thought that Germany's "renewable energy priority law" (EEG) remains one of the best one so far clean energy legislation, He said that the bill not only created a market in Germany, very good to encourage competition in the market for the industry's enterprises to establish a clear long-term picture for the future, and created a good framework for FirstSolar and other Companies continue to reduce costs, and thus the future development of new energy markets.

PV market in Europe in recent years have begun to shrink so that FirstSolar fought in China. September 8, 2009, FirstSolar announced in the next 10 years in Inner Mongolia Erdos (Quote stock bar) to build the world's largest installed capacity of 2000 MW solar power station, the project investment of up to several billions of dollars. This is the first big U.S. companies to enter the field of PV.

According to the company the information provided, the project is expected to be launched this summer, the first phase of 30 MW demonstration project, two, three, and four projects were 100 MW, 870 MW and 1,000 MW. Phase II and III will be completed in 2014, while the four works will be completed in 2019.

FirstSolar in Europe, the Middle East and Africa Corporate CommunicationsDirector, BrandonMitchener said, according to company and signed by Erdos Cooperation.Memorandum of Understanding for implementation of the project, the company will actively examine and evaluate the establishment of manufacturing facilities in China, the feasibility and related issues, but the specific time and place not yet been determined.

Camcorder Battery F.A.Q. & Tips

• Camcorder Battery Usage Tips


1. A new camcorder battery comes in a discharged condition and must be charged before use (refer to the devices manual for charging instructions). Upon initial use (or after a prolonged storage period) the digital camcorder battery may require three to four charge/discharge cycles before achieving maximum capacity.
2. When charging the camcorder battery for the first time the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Remove the digital camcorder battery from the device, reinsert it and repeat the charging procedure.
3. It is important to condition (fully discharge and then fully charge) the camcorder battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run the device under the digital camcorder battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual.
4. If the camcorder battery will not be in use for a month or longer, it is recommended that digital camcorder battery be removed from the device and stored in a cool, dry, clean place.
5. The milliamp-hour (mAh) rating of the Hi-CapacityT camcorder battery will often be higher than the one on the original battery. A higher mAh rating is indicative of a longer lasting (higher capacity) battery and will not cause any incompatibilities. A Hi-CapacityT digital camcorder battery will, in most cases, outperform the original by 30% to 50%.
6. New camcorder needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity. Rechargeable batteries undergo self-discharging when left unused. Always store a digital camcorder in a fully charged staged for storage.
7. Don't short circuit terminal or store your digital camcorder with metal parts. Don't connect and disconnect the camcorder within a short interval to prevent irregular charging of the rechargeable battery.
8. It's okay to use different brands of digital camera batteries in the same device -- for example, Energizer, Duracell, and generic. Voltage is voltage, and the device neither knows nor cares that made the camera batteries you put in it. Remember, you can mix brands but not types
9. Camera Batteries self-discharge quicker when it's hot. They're fine at room temperature, but once it's over 90o or so, they'll start losing their charge faster. So don't leave digital camcorder in a hot car.
10. Don't overheat. Do not attempt to charge non-rechargeable batteries. This will overheat them and could cause a fire. Keep camcorder batteries out of hot places, like your car. Your car can be an oven, and baking your digital camcorder batteries shortens their life.
11. Store properly. Keep your camera batteries in a cool, dry place. The refrigerator is cool, but not dry. You could store your camera batteries in the refrigerator and maximize their life by using a silica gel to keep the batteries dry. This however, is an expensive and inconvenient option.
12. Don't short the connections. Keep your camcorder batteries organized. Don't let the ends touch the wrong thing or you'll short the digital camcorder battery.
13. Don't mix and match your camcorder. Use the same chemistry and brand. Never mix rechargeable and non-rechargeable batteries. That's very dangerous to you digital camcorder
14. Invest in a good charger for your camcorder. NiMH batteries should not be charged in a NiCad charger, unless the charger is specifically made for both chemistries. There are cheap chargers and there are expensive chargers. Make sure the charger you get has good reviews and is well made. Chargers with micro-controller chips are usually the best choice of your digital camcorder.
15. When charging your camera batteries occasionally discharge them fully before recharging them. This is especially helpful to NiCad batteries. Be careful not to discharge too deeply. (Less than 1v per cell for NiCad and NiMH. E.g., a 3.6v pack to no less than 3v.) Discharging to absolute zero will make your battery useless. It's best if you have a charger with a conditioner that will cycle the digital camera battery for you.
16. Be sure to store your camera batteries properly. Do not leave your batteries in a hot car, or in humid conditions. The best storage conditions are a cool, dry place. The refrigerator is fine if you stick in a packet of silica gel with your digital camera batteries in a sealed bag to keep them dry. It is a good idea to charge your NiCad or NiMH batteries fully before use if they have been in storage.
17. Many camera battery packs are made up of individual battery cells. When digital camcorder batteries are purchased to be made into a pack it is a good idea to equalize the charge on the batteries before building the pack.
18. Equalizing the camcorder batteries is nothing more than ensuring the voltage on each cell is within a very close range at the same state of charge (i.e. fully charged).If you do not equalize the batteries properly before building a pack, the charge and discharge cycles will be harder on some of the cells and will effectively shorten their life. Once a cell fails the entire digital camcorder pack will be weaker because of the one defunct cell.
19. The first way is to connect the set that will go in the camcorder pack in a parallel configuration. Leave them in this state for at least 24 hours. The cells that have a higher charge will charge the ones with a lower charge and digital camcorder will all equalize.
20. Camcorder Rechargeable batteries have been around for quite a while, and if you have been around for a while too you probably remember all the trouble with digital camcorder rechargeable batteries when the NiCad (Nickel Cadmium) rechargeable batteries first came out. There were major problems with memory effect and poor performance and most consumers gave up on using them before the technology had much of a chance to improve

Lithium ion battery, how much you know?

Ni-MH battery main features:
1． Ni-MH battery energy density than nickel-cadmium batteries twice as large;
2.can reach 500 times the full cycle of charge and discharge;
3. using a special charger can charge one hour quick charge;
4. self-discharge characteristics of a good than the nickel-cadmium batteries, charge can be retained after a longer period;
5. up to three times the continuous and efficient discharge; can be applied range: cameras, video cameras, mobile phones, cordless phones, walkie-talkies, laptop computers, PDA, a variety of portable devices and electric power tools.
nickel-cadmium batteries
Nickel-cadmium batteries can be repeated in more than 500 charge and discharge, economic and durable. Its internal resistance is small, both the internal resistance is small, fast charge, but also to provide high current load, and the discharge voltage change is very small, is a very good DC power supply batteries. Compared with other types of batteries, nickel-cadmium batteries can withstand overcharge or over discharge. Nickel-cadmium battery discharge voltage is different according to their discharge device, each unit cell (Cell) is approximately 1.2V, the battery capacity of units of Ah (AH), mAh (milliamp hours), discharge voltage limit, said the termination of to "discharge termination voltage", nickel-cadmium battery discharge termination voltage 1.0/cell (cell for each cell batteries).
Self-discharge rate is low, nickel-cadmium batteries were placed in long cases, properties do not deteriorate after fully charging the full restoration of its original features, it can be -20 ℃ +60 ℃ temperature range. As the unit cell using metal containers, sturdy and durable; completely sealed manner, does not appear electrolyte leakage phenomenon, there is no need to add electrolyte. To improve battery performance and extend battery life The key is to avoid memory effect and excessive discharge. Nickel-cadmium batteries have memory effect, namely, nickel-cadmium power in several low-volume after working under the charge and discharge. If you want to conduct a large-capacity charge and discharge, the battery will not work, this shall be memory effect (Memoryeffect).
Memory effect makes the discharge termination voltage is set higher video recorders, camcorders, with the lower operating voltage, battery capacity of the surface, also with the reduced, but the discharge voltage reduction may be one or two fully discharge caused by the temporary phenomenon. Memory effect makes the performance of the battery can not be brought into full play, but also cause great inconvenience to the shooting. Thus, in use should pay attention to the use of the charger with a charge-discharge performance, such as Sony's BC-1WDCE, to avoid the memory effect of the production, such as the use of general charger BC-1WA, BC-1WB, it would be about 10 times After the charge to conduct a discharge, but also can reach the purpose to prevent the memory effect.
For nickel-cadmium batteries, each unit cell (Cell) voltage is 1.2V, therefore, 12V there are 10-cell battery (Cell) composed of 13.2V on Cell from 11 composed of the capacity of the battery to full state of charge-discharge to each unit cell (Cell) of 1.0 to represent, such as NP-23, NP-40, BP-95 suffix shall be the capacity figures are 2.3Ah, 4Ah, 9.5Ah and so on. Discharge termination voltage and full discharge does not mean that a unit cell voltage 0V, each unit (Cell) battery discharge to 1.0V means that when the over-discharge, over-discharge the battery will be there should be no damage, should be avoided.
lithium batteries
Newly-to-market with a large-capacity lithium battery, high-density, compact lightweight features. Because it has the NP-type battery is compatible with the size of other existing specifications and other particular specification, the user is very convenient in use. Because it is an ideal environment pollution-free batteries, which is characterized by: high energy, its energy is high-capacity nickel-cadmium battery 1.5 times; high density, the density of nickel-cadmium batteries two times the average working voltage is 3.6V . Operating voltage flat and large capacity, so that the camera can run uninterrupted for several hours of work, the load characteristics can be reflected in the 2C discharge, greatly satisfied the conditions in the emergency use. It can be a large temperature range, operating, discharge temperature range up to -20 ℃ +60 ℃.
Lithium battery is an excellent ideal battery, it is economical and practical, flexible, convenient, general shooting 1-2 batteries can now be responsible for the entire mission, but it impatience Overcharge, over-discharge and excessive current, so when excessive voltage and current of the passage is easy to produce short-circuit phenomenon, may also lead to dangerous, causing bodily injury and battery scrap, so lithium batteries are generally set up to protect the circuit, just in case the battery can be incorrectly used or charger to poor condition lead to too much voltage is passed, the circuit can be automatically cut off the circuit to ensure that the batteries and equipment safety and to avoid bodily harm. When used in the battery warning indicator light flashes when the timely replacement of new battery, should try to avoid excessive discharge, the non-10000 in unusual circumstances not to 2C discharge. As much as possible so that the battery used in the specifications. Lithium battery charging can accurately display the current charge amount, but also has the residual capacity display, LED section in order to express their residues. Durable and lightweight high-performance lithium batteries flexible, and greatly facilitate the television crews filming and Creation. Large capacity lithium battery, long life, pollution-free, light weight, no memory effect, self-discharge rate is low, high temperature or low temperature, can be used in a wider area, but are expensive and need to use a dedicated charger.
use and maintenance of batteries
Battery life is the use of a period of time, the charge-discharge capacity fell to 80% of the nominal capacity prior to the charge and discharge times they are not charging and discharging or complete failure is the battery life; self-discharge rate refers to the battery fully charged after Place the case of a long time without the slow self-discharge phenomenon. Self-discharge rate is low that a long time, after placing a small decline in capacity.
For the shoot out a program or news coverage, generally the use of portable video recording devices, and portable video recording devices supporting the use of batteries, whether efficient, high-quality work carried out to ensure continued long-term smooth filming the crucial link. The normal functioning of the battery with our TV, audio-visual education workers in their daily work in the proper use and careful maintenance are closely related, so the use and maintenance issues should arouse our attention.
1.in their daily work, it should be familiar with their own type of battery, it has the basic characteristics and performance. This guide us in the proper use and maintenance, is of great significance, for extending the battery life is also extremely important.
2.charging at room temperature is best controlled at between 10 ℃ -30 ℃, the right temperature higher than 30 degrees Celsius is best to take measures to avoid overheating occurred due to internal deformation of the battery; room temperature below 5 degrees Celsius, it will result in charging inadequate, affect the battery life.
3.the battery after a period of time after use, due to varying levels of discharge and aging of the existence of more or less inadequate charging and performance decline, under normal circumstances nickel-cadmium batteries can be about 10 times the charge and discharge cycles were followed by a one-off charge. Approach is to extend the charging time than the normal charge time extended approximately doubled. Specific examples are as follows: With SONY's BC - 1WA (B) Charger for NP-1 battery, in the green light flashes when fast charging, the green light stops flashing light when the fast-charge end of a long charge bit by bit began bit by bit to extend the charging time, charging time bit by bit over charging time, over 3-4 hours recharge time is appropriate.
4. the battery charge and discharge should be strictly in accordance with requirements and standards, avoid long-term overcharge, over-discharge, or charge less frequently. Does not completely discharge the battery when using the long-term or short-circuit for small current depth of discharge is caused by the battery capacity decline in life expectancy shortened important factor. Over time the use of action would not only affect illegal to use, but will certainly affect the battery capacity and life span.
5. in the popular BC-1WA (B) charger, the battery charging process should be a complete power failure can not be half-way or at the end of fast charging, the battery in a high-temperature state, re-connect the power, making quick battery charger once again charge, the results would impose an excessive charge. In use indicator flashes when the battery warning alarm, they should replace the batteries in time to avoid excessive battery discharge.
6. nickel-cadmium batteries Needless to charge when not in use a long-term preservation, however, it must discharge to the termination of the battery voltage (a video camera battery warning lights flashing) may be stored in the original packing carton packaging or cloth, paper packaging, the place dry ventilation Department store.(Come from:www.all-power-accessories.com)

Google Nexus One phone will have the AT & T 3G version of the listing

Google Nexus One smart phones will soon appear to have used AT & T 3G services, the version listed.Users have to buy 529 U.S. dollars can not lock Nexus One, but this last month of the Android phone's 3G frequencies are supported, only T-Mobile USA are supported.

This means that if users want to use AT & T's SIM, please be able to use the 2.5G or EDGE network services. Yet even though the AT & T has been criticized for poor quality networks, but the company's 3G coverage is still large compared with T-Mobile.

However, users want Google Nexus One will soon have other options. According to a document sent to the FCC, there is a new version of the Nexus One will use the WCDMA Bands I, II and V frequency, that is, AT & T and Canadian carriers Roger, Bell Canada and Telus Mobility are using the frequency. The device can also be almost universal in Europe.

（CNET Technology News Network International reported February 3）

This means that these networks can be used on the new version of the Nexus One should be available in the near future. Google has said will be to create a service using the Verizon and Sprint Nextel's version is expected this spring.

FCC documents show the file will be posted on the latest Nexus One new examination on the phone tag. If you contrast the original version of the Nexus One label, can be found that they had come within a yard. The new FCC ID is NM899110, while the original version is NM899100. One of the facts show that this short of the new phone is a variant version of the previous paragraph.

Windows 7 warning to replace the battery? Perhaps it is a lie to you

Microsoft said that they had started to investigate what is the reason for Windows 7 users in the case of the battery no problem, but the battery in question receive their warning sign.

A Microsoft representative said in a statement Tuesday: "We have and our hardware partners to work together in the investigation, it looks like, and hardware-related."

This issue in the warning signal comes when the computer's BIOS will go to determine whether this computer's battery needs to be replaced. In some cases, this signal will appear, and some users will receive this warning, even if their battery is fully no problem.

But because of this warning was on the new features in Windows 7, so users come from the Vista upgrade when you see this warning, we should not ignore. Microsoft recommends that users contact them is to buy a computer manufacturer to confirm whether this warning in the warranty.

At the same time, Microsoft and computer vendors have said they tried to find where the problem lies in the co-operation. Microsoft said: "We and our partners, trying to find out what are the reasons and if we have discovered will be immediately posted on the forum."

Acer, Taiwan's President: has no intention of confrontation with the Apple iPad

Acer, Taiwan's president, Lin Hsien-Lang (Scott Lin) said that Acer's business in 2010 focused on ultra-thin notebook, no intention to jump into the sudden outbreak of flat-panel machine market, and Apple iPad confrontation.

Lin Hsien-Lang pointed out that the design iPad categories of products, Acer is right there is no technical difficulty, but this product does not comply with Acer's business model, because Apple's iTunes store through the provision of ecosystem support, including Acer, including the other Manufacturers little capacity and experience in this area, want to copy Apple's closed model is not realistic.

However, Lin Hsien-Lang that, iPad is unlikely to notebooks, Internet impact in this market, because they are completely different consumer-oriented crowd.

In 2010, Acer is expected to be the traditional large-size notebook notebook shipments accounted for 50-60% of the total, ultra-thin models accounted for 20-30% and another 20% of the online book, less than 20 mm thick notebooks will be Acer's a major focus of this year.

Lin Hsien-Lang also cites data from market research firm, said in 2009, Acer shipped about 31 million notebooks.

Apple Tablet PC second paragraph: Like Mac Non-iPhone

Bubble NetNews Channel February 2, according to foreign media report today, sources, Apple iPad in the development, while also developing other a Tablet PC. Larger device, more like a Mac, rather than the iPhone。

Rumors

Before the release of the iPad last Wednesday, there related to rumors that Apple might introduce two different sizes of tablet PCs. A 7-inch or so, while a 10.6 inches. Ultimately proves, iPad actual size of 9.7 inches. However, sources said Apple is developing a larger device, the largest is expected to reach 15.4 inches, with the existing MacBook Pro notebook is similar.

Although for the iPad, the 15.4-inch too big, but the sources said, this product is very different with the iPad. The product will be closer to the Mac, but will run the OS X operating system.

If this is true, Apple is expected as early as June of this year at the "Worldwide Developers Conference" posted on the product. Apple usually released at the event, the new iPhone, but Apple's Mac platform is also the developer of the most important an event, and the OS X operating system over the past two years has become a major component of the General Assembly. Including two years ago, Snow Leopard (OS X 10.6) surprise appearance, allowing developers to be as early as possible to see the true capacity of the product.

Earlier reports said that the developer will be at this year's Worldwide Developers Conference in advance to see OS X 10.7. If the OS X 10.7 is equipped with a number of important multi-touch capabilities, it is likely to be used in Apple's second paragraph of the Tablet PC. Of course, there may be used with touch-screen iMac.

As in the past, Apple likely will never be disclosed in the development of a number of projects for the second tablet PC might be just such a project. However, sources said, the new product will be released within the next year.

Details Forecast

The new product uses, may be iPad completely different. For example, the product is more likely to become a laptop or desktop directly alternatives. Therefore, it will almost certainly be equipped with an external keyboard and stand. Do not use brackets, you can hold in your hand the same as the iPad, or on his knees, through the touch screen for input. When using the bracket, you can make use of the Bluetooth mouse and keyboard for input.

According to a number of patents submitted by Apple as well as the launch of a large number of touch devices, Apple certainly has touch as a direction for the future development of computing technology. From the traditional notebook computing devices to such a new transition process, a large flat-panel computer can act as a good transition. iPhone makes a large number of users adapted to the touch screen, and thus laid the foundation for the iPad, while the iPad may also play a similar role, allowing users to advance to adapt to this new Tablet PC.

Despite the larger size of the Tablet PC is undoubtedly a higher price than the iPad, but if Apple is really positioning the product as a laptop alternative, then the price is still much room. If so, even if the price of more than 1000 U.S. dollars is also reasonable, which is vastly different with the iPad.

However, using this pricing, the user would want the product to provide the same powerful performance as the notebook. According to sources, the same as with the Mac, Apple has the potential to this product is equipped with Intel processors, rather than iPad used A4 processor. As a result although the performance will be improved, but it will be a corresponding increase in power consumption. Large touch screen with a larger chip power consumption will make this product the battery life of 10 hours less than the iPad. But as long as more than 5 hours, we can make the majority of customer satisfaction. Apple in the past few years has been battery life, there have been some competitive advantage, enabling their notebook battery life is much higher than the industry average.

As for weight, iPad weighs about 1.5 pounds (about 0.68 kilograms), while the screen size of 13.3-inch MacBook Air weighs about 3 pounds (about 1.36 kilograms). If Apple can be the keyboard and touch pad such as the unnecessary part of the MacBook Air removed, even with a larger screen, is still likely to be the weight of new equipment under 2 pounds (0.9 kilograms) to 3 pounds. But with such a large screen, it is necessary to provide a strong enough coat, carrying the process to avoid damage to the screen.

As for the OS X applications can or whether it will support multi-touch, is still hard to say. Safari obviously very easy to implement, but they need to re-design of other applications will be able to support this feature. But, as we have seen iPad conference, Apple do not take too long, you can modify the iWork suite of applications. Third-party developers may also be obtained from Apple's excellent set of development tools, the application upgrade.

However, all the above is just tip of the iceberg, but Apple has not been confirmed, the final message has yet to be announced Apple's end.
