IBM 02K7039 Battery

Comparison of Laptop Computers


The purpose of this comparison is to help prospective laptop IBM Laptop Battery purchasers in their decision. In today's mobile climate, the average person can make good use of a reliable portable computer; this report is designed to help in that search. Of the many perspective computers, only several brands have been selected for this comparison. Those that have been selected are Pentium computers that boast the new MMX technology. MMX technology lends itself to portable computers because of the added internal processor cache, graphics acceleration, and lower power usage. The first two features add to the speed of the machine and the last to the travelling lifetime.

This report will compare laptop computers on the basis of the following: (1) features, (2) performance in hardware tests, and (3) price.


Options for Laptop Computers

Of the many laptops available,IBM 40Y6799 Battery some equipped with MMX, only four specific computers were chosen. These computers are equipped with MMX processors and stood out among other MMX computers for their performance as well as their value. Those chosen for this comparison are the Compaq Presario 1080, the Dell Latitude LM M166ST, the Gateway 2000 Solo 2200 166MMX, and the Micron Transport XPE P166. These computers all have Pentium 166 processors with a variety of other features that will be discussed in the following.

Points of Comparison

The industry of computers is an ever growing and continually more IBM FRU 92P1139 Battery competitive market. Many computer manufactures are emerging with well made, reliable systems that make a valid argument for themselves. Several of these computers are discussed below.

Features. Many different features are available on today's computer, but only the standard, essential features will be discussed here. These features are grouped into subheadings below for ease of use.


Memory: Each computer has a processor speed of 166 MHz. The Compaq has the least amount of standard memory with 16 MB, with a maximum of 48 MB. Both the Dell and Gateway computers come with 40 MB installed with their maximums being 72 and 80 MB IBM FRU 92P1141 Battery respectively. The Micron had the most standard memory at 48 MB, having a maximum at 80 MB also. The Micron machine rates best in this area [1:144-145].


Weight: For laptop computers, travel weight, that is the weight of all of the required equipment and carrying case, is very important. The Compaq and Dell come in with the lowest travel weight at 8.5 pounds. The Gateway came in right behind them with 8.6 pounds travelling. Of the four computers, the Micron was the heaviest, weighting in at 9.1 pounds. The Dell and Compaq are the best in the weight department [1:144-145].


Battery: Another key factor for laptop IBM FRU 92P1137 Battery computers is the length of time they can operate away from an outlet. The Dell computer had the longest rated battery life with a rating of 4 to 5 hours. Compaq's computer had a rating of 3 hours while Gateway and Micron's laptops were rated with 2.5 and 2.25 hours, respectively. Dell's computer has the best rating for battery life [1:144-145].


Storage: All computers rely on their storage unit to operate for the use of programs and storing information. The Presario had the smallest standard hard drive at 1.4 GB. Both the Dell and the Gateway computers had 2.1 GB hard drives. Micron rates at the top for this category for its 3 GB hard drive [1:144-145].

Overall, the Latitude from Dell gets the best rating for this section. It's light weight and long battery life aid in portability, and while its hard drive and memory are average for this group, they are more than sufficient for good IBM 02K6651 Battery performance.


Performance. The various machines were put through their paces to determine their comparative performance. The several different tests are listed below as well as the various computers' performances. The numbers don't mean much on their own and are best used in comparison.


Windows applications: The various computers were tested and scored on the execution time of eight top-selling Windows applications. The Compaq had the lowest score with a 29.4. The final three scored fairly closely together with the Dell coming in at 36.6, the Gateway having a score of 37.5, ad the Micron having a score of 39.5 [1:140-141]. The Micron ranks at the top of this category.


Processor: These tests were run by exercising the IBM 02K6928 Battery processor and memory with test that mirror the processor usage of many Window programs. The Latitude has the lowest rating at 322. Next in order for performance was the Presario at 328. The final two machines are fairly the same in this test with the Gateway testing at 331 and the Micron at 332 [1:140-141]. The Micron comes in at the top of this category also.


Battery: Battery life was tested by performing a combination of down time and heavy activity for the extent of the battery lifetime. The Micron and Gateway computers ranked at the bottom with 2 minutes 20 seconds and 2 minutes 19 seconds, respectively. Dell's Latitude was next with a battery life of 2 minutes 30 seconds. Finally, the Compaq was rated at 2 minutes 32 seconds [1:140-141]. The Compaq was at the top in this category.

In this battery of tests, the Micron appears to be the leader. Although the battery life is lower than two of the machines, the difference IBM 02K6620 Battery is not enough to negate the Transport's superior performance in the other tests.


Cost. The computers were priced by the manufacturers suggested price, but the prices grow considerably when adding options. The Compaq Presario sells for $4,299 for the average mail order price. The Latitude priced at $3,999 direct. Gateway's system can be purchased for $4,724 direct. Finally, and most expensively, the Micron sells for $5,199 direct.

Conclusions

Table 1 IBM 02K7039 Battery illustrates the preceding comparison of features, performance, and cost. From this information, the following conclusions can be stated:

The Dell is best in the features in terms of portability and average for the other areas.

The Micron Transport covers the other aspects with high end hardware, but is somewhat heavy and the battery life is short.

The Transport leads in most of the performance areas and is not far from the front in the area of tested battery life.

The Gateway computer performs very well behind the Micron machine.

The Micron computer is the most expensive with the Gateway computer being reasonably priced behind it.

Although the Micron and Dell laptop computers provide slightly better performance in certain areas, these advantages are not worth their higher price tags.

The Gateway laptop provides essentially the same features and performance as the Micron but at a lower price.

The Gateway laptop computer is the best choice based on the preceding IBM ThinkPad X60 Battery, conclusions.

Recommendation

Based on these comparisons, I would recommend the Gateway computer. It performed well in all of the tests and had good standard features for the price. Also, it was priced lower than the Micron laptop.

IBM ThinkPad T40 Battery

Refilling laptop batteries!



The Li-Ion battery in my IBM Thinkpad X31 laptop has been getting a bit long in the tooth. Rated at a 4.4 AH capacity new, /proc/acpi/battery/BAT0/info told me that it was only holding 1.8 AH now that it was a few years old. (This is normal for Li-Ion batteries, which degrade over time, even without multiple charge-discharge cycles.)


A brand new IBM (or Lenovo now) battery IBM Laptop Battery costs over a hundred dollars, but by shopping around I was able to find a "compatible" battery for as low as $50. It was only rated at 4.4AH, but that is relatively close to the 2nd generation 4.8AH batteries that IBM/Lenovo sell for twice as much. I started to wonder if it might be cheaper to buy  OEM li-ion cells and simply replace the cells (keeping the case, and charge/discharge electronics). The first step would be to determine what type of Li-Ion cells I'd need to buy, so I decided to open up my old batteryAs you can see, the standard X31 battery has six cells, in three parallel groups of 2. Cells are nominally 3.6volts, so this adds up to 3 x 3.6 or 10.8 volts. In the photo I have removed the shrink wrapped packaging from one cell to view the markings. Note the relatively complicated PCB along the back side of the cells that handles charging and discharging. If you zoom into the photo, you can see that the controller PCB is connected to each end of every pair of cells (orange and black wires to the far ends, silver metal tab connections to the middle two). This allows the controller to charge each parallel pair of cells at a different rate. The controller PCB is also connected to a thermocouple that is resting between the two middle cells. This gives the controller a temperature reading on the cells during charging and discharging. If the PCB detects that the temperature is too high, it can lower the charging rate, or shut down the power draw (and laptop).  Also note the heat fuse (small white block in series with the power line between the two leftmost cells) that is designed to open the circuit if the charge/discharge IBM ThinkPad T40 Battery, controller for some reason fails to maintain a safe temperature. All of these safeguards are designed to keep your laptop battery from igniting, and will be very important to maintain in any "re-manufactured" batteries.


I actually determined what type of li-ion cells were used by measuring them and then looking for li-ion cells of a similar size. They are about 2.5" high by 11/16" diameter, or very close to the 64.9mm x 18.3m diameter size of a 18650 style cell that I found on www.batteryspace.com.


My battery is rated at 4.4AH, or 4400mAH. As it has three sets of parallel cells, each set of two cells must have a 4400mAH capacity (because they are in series, you add the voltage, not the amperage), so each cell must have a 2200mAH capacity. 


From a mAH per dollar standpoint, batteryspace.com's 2000mAH cells are the best value, but I decided that since the total cost difference was only six dollars, I could afford purchasing the 2200mAH cells. These are slightly lower than the 2400 mAH capacity of the newcells that Ibm/Lenovo now use, and I'll end up with a 4.4AH battery (just like the original part number, before IBM/Lenovo upgraded it to 4.8AH).


Just the cells cost $34.20, but I chose to purchase IBM ThinkPad T41 Battery them with solder tabs attached (an extra $1.50) because I figure the people at batteryspace.com are better than me at attaching tabs, plus having extra tabs to work with (those that come on the cells, plus those I salvage from the original cells) will make my life easier. (Besides, the $7 of shipping is the largest extra expense….if the 2600mAH cells weren't almost twice as expensive as the 2200mAH cells I'd have gotten them just get a 5.2AH capacity battery!) The total cost was $43.42. A week later my batteries arrived. (Thanks UPS!)

ThinkPad T60 battery

Is Apple Sticking Its Head in the Sand?

It’s human nature to get on the bandwagon of a “good thing.” Take the screaming hype that is the netbook phenomenon,IBM Laptop Battery, for example. Although it’s clear the netbook trend is real, my hype meter wagged over into the “tilt” field when I read these words from Dan Nystedt of the IDG News Service:


“The network will truly become the computer, as Sun Microsystems used to say. Or in more modern terms,ThinkPad T60, 40Y6797, 40Y6799, FRU 92P1139, FRU 92P1141, FRU 92P1137, the Cloud for consumers will have arrived.”


Nystedt was writing to express surprise at Apple COO Tim Cook’s recent negative comments about netbooks. Like Nystedt, I don’t think any computer manufacturer can afford to ignore the netbook trend. I’ve even suggested in the past that Apple deliver a low-cost, netbook-style Mac.


I also can’t agree with Cook that the netbook experience is voided by what he described as “cramped keyboards, terrible software,ThinkPad T60, junky hardware, very small screens, and just not a consumer experience” during a quarterly financial conference call on Wednesday. On the other hand, Cook’s apparent condemnation of all existing netbooks does not mean that Apple is pooh-poohing the entire idea. Macworld’s editor in chief, Jason Snell, makes this point better than I could in his article Apple to netbooks: Drop dead.


Snell writes: “Apple … often runs down its competitors in a category before introducing its own game-changing product in that category.” I’ve found that statement to be true as well.


If you buy into that interpretation, Cook’s comments imply that Apple’s netbook product, if it has one,40Y6797, is likely to be one of two things:


1.) An iPhone 3.0 software-based, iPhone-derivative tablet-like device that Apple does not at all position as a netbook, but that is likely to be half smartphone, half small form-factor computer. Apple’s incredible success with its iPhone App Store has to be factored into the advantage that such a device would have.


2.) A lower-cost Mac with limitations that keep it from cutting into other Mac sales,ThinkPad T60, 40Y6797, 40Y6799, FRU 92P1139, FRU 92P1141, FRU 92P1137, but with a very intriguing, game-changing hardware design. More than likely, this option isn’t close to launch.


Meanwhile, Microsoft is also positioning Windows 7 for netbooks, and the message seems to be clear to me — it’s aimed at netbook manufacturers: 40Y6799, You want to use Windows 7 on netbooks? We’re going to use some of our power at generating negative press to out-muscle you into paying the full notebook freight for Windows 7 instead of the lesser price for reduced-functionality Windows 7. Microsoft isn’t targeting this at netbook buyers. If it were, it wouldn’t be sending the message now. It would wait and quietly slip it under the rug at Windows 7 launch time.


I bet Microsoft wins this game, too. If your company requires Microsoft Office, and it’s thinking about buying netbooks, it needs Windows XP or Windows 7 on those netbooks. Either way, limiting simultaneous apps to three is an IT helpdesk headache waiting to bloom.


But the netbook phenomenon isn’t really about Apple or Microsoft. At least, not yet. And this is the kicker: Many people love the small form-factor, light-weight design of netbooks. Such computers are appealing to a wide range of potential buyers, FRU 92P1139, everything from casual computer users to on-the-go and even advanced business people (as travel computers). And there can be no denying that more and more enterprises are considering netbooks because of their need to reduce costs in a tough economy.


That brings me to the main point:ThinkPad T60, 40Y6797, 40Y6799, FRU 92P1139, FRU 92P1141, FRU 92P1137, It’s really no secret why the netbook phenomenon got kicked into high gear about six months ago. It’s about money and the most severe economic downturn in most people’s lifetimes. Take that out of the equation, and netbooks would still be on the rise, but they would be being considered by far fewer potential customers. So a big part of the netbook hype cycle was fueled by the money savings. Nothing wrong with that. But I question whether it’s a long-term phenomenon.


What’s going to happen when the economy comes back? It probably won’t happen overnight,FRU 92P1141, since many people’s financial change in perspective will linger long after the downturn becomes history. But the strongest motivator — saving money — will no longer be there. And the focus on netbooks may start to dissipate at that point. The desire to save money is not enough of demographic on which to hang a rapidly growing product category.


Cook has a point, too. The cramped keyboards, limited OSes and apps, constrained specs, and small screens may get old for at least some netbook users over time. Less is more only to a point. And then it just becomes, well, less.


The single most important factor in the future of notebooks, however, may not be the economy or even the netbook OS platforms like Android, Linux and Windows 7. The future of the product category probably hinges on hardware innovation yet to arrive.ThinkPad T60, 40Y6797, 40Y6799, FRU 92P1139, FRU 92P1141, FRU 92P1137, It’s an immature product category. If hardware makers can move beyond making very small portable computers cheaply with well considered trade-offs,FRU 92P1137, and can transition into creating hardware that becomes more or less indispensable, that’s what will make the trend stick.


The obvious direction for that kind of innovation would be convergence of netbooks with smartphones. That’s the direction that many Android-based netbooks are likely to head. But could mobile convergence divide the netbook category in two? I think that’s quite possible. Netbook buyers are not all highly mobile, nor are they all interested in paying the monthly subscription fees for 3G data services.


I don’t have the answers. No one does. But the questions are fascinating enough on their own

ThinkPad X60 battery

Nvidia: For Smartbooks, Windows CE Beats Android

Despite the hype surrounding Google Inc.’s Android operating system, Nvidia Inc.IBM Laptop Battery, sees more immediate promise in Microsoft Corp.’s Windows CE for ARM-based netbooks.


Mike Rayfield, general manager for Nvidia’s mobile business unit,02K6651, 02K6928, 02K6620, 02K7039
ThinkPad X60, FRU 92P1167, said Nvidia preferred Microsoft’s Windows CE over Android because of CE’s maturity. He said Android currently has a rough user interface.


Rayfield also plugged Nvidia CEO Jen-Hsun Huang’s prediction yesterday that Tegra, Nvidia’s System-on-Chip (SoC) for ARM hardware, could account for half of Nvidia’s revenue within a few years, while also reaping higher profit margins than Nvidia’s current products.


Rayfield was coy, however, regarding reports that say Microsoft’s upcoming Zune HD media player will use Tegra.


“Microsoft hasn’t confirmed that …02K6651, so until they comment, I can’t,” he said.


For smartbooks, Nvidia is working with Microsoft to optimize Windows CE when it runs on Tegra. The counterpart to Nvidia’s Ion platform for Intel Atom-based netbooks, Tegra bundles an ARM CPU (the 750 MHz ARM 11) with specialized chips designed by Nvidia for graphics, HD video encoding and decoding, stereo sound and more.


That will allow Windows CE devices to offload much of the heavy multimedia work onto Tegra, 02K6928,resulting in better performance, 1080p video, and low power usage. Nvidia claims that Tegra smartbooks should allow users to listen to music for 25 days or watch HD video for 10 hours, versus 5 hours and 3 hours, 02K6651, 02K6928, 02K6620, 02K7039
ThinkPad X60, FRU 92P1167, respectively, for an Intel Atom netbook.


Nvidia chose to work with Windows CE first, said Rayfield, because it “is a rock-solid operating system that has been shipped billions of times.”


Windows CE also has a “low memory footprint and a good collection of apps,” Rayfield said.


He said Nvidia is also improving Tegra for use on Windows Mobile, a close variant of Windows CE, for ARM-based smartphones.


Nvidia is working with Google to accelerate Android, which is based on Linux, when running on Tegra hardware. 02K6620, But it will be about a year before that delivers for smartbooks, due to existing limitations in Android, he said.


For instance, Android screen icons that fit on smartphone screens (usually 4-inches and under) are oversized on a smartbook’s 8- or 9-inch screen, he said.


Also, all video and graphics rendering in Android is done today by the operating system’s Java code, a technique he says is too slow for HD video.


“There’s no hardware acceleration. It’s all software,” Rayfield said. “Everyone’s talking about Android for cell phones, but the reality doesn’t exist for the larger displays [of a smartbook.]”


A Google spokeswoman declined to respond to ,02K7039, Rayfield’s comments about Android.


Rayfield’s comments echo those about Android by others in the emerging smartbook space. Kerry McGuire, director of strategic alliances at ARM, told Computerworld recently, “I do think that there is more work that can and will be done to bring the things we love about Android into form factors [such as netbooks.]”


Rayfield evinced even less enthusiasm for more mainstream flavors of Linux available on ARM,02K6651, 02K6928, 02K6620, 02K7039
ThinkPad X60, FRU 92P1167, such as Canonical’s Ubuntu or Intel’s Moblin.


“The world soundly rejected the first netbooks that came out with Linux,” he said. “Printers didn’t work, and devices didn’t get recognized. The whole thing was a mess.”


Nvidia has garnered 42 design wins from 27 different manufacturers all building devices using Tegra, said Rayfield. More than half of the wins (26) are for smartbook or tablet designs.ThinkPad X60, Those can arrive to market in just six months, versus two years for smartphones designed for telecom carriers, Rayfield said.


Rayfield echoed comments by Nvidia executives during its analyst day on Tuesday that Tegra could make up more than half of Nvidia’s sales ($3.4 billion in fiscal year ending January 2009) very soon.


“It’s an aggressive statement, no doubt. But we’ve got a pretty good pipeline,” Rayfield said. Also, it won’t be long before consumers, rather than re-ripping Blu-ray movies to watch on different devices, will expect to be able to carry a single, HD-quality version of their videos around with them for easy sharing and viewing on large-screen TVs.


By using its own graphical expertise in Tegra rather than licensing it,02K6651, 02K6928, 02K6620, 02K7039
ThinkPad X60, FRU 92P1167, Nvidia hopes to reap gross profit margins of 45% on Tegra by charging commensurately for its better performance over competing platforms from Qualcomm (Snapdragon) and Freescale Semiconductor, Rayfield said.


The next generation of Tegra due early next year will boast 4 times the performance of today’s version,FRU 92P1167, while the 2011 update will improve performance 10 times over today’s, he said.

ThinkPad T43 battery

Catalyst: A fuel cell system must be high efficiency and high specific energy. To obtain high efficiency and high specific energy, it is necessary to improve the gaseous fuel and oxidizer in the process of the electrode reaction, namely, research and development of efficient catalysts. ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193,At present,IBM Laptop Battery, the use of other inexpensive and effective catalyst for the replacement of the precious metal catalyst to become one of the catalysts.


The feasibility of fuel cell



dell inspiron xps m1710 battery, so Western countries such as Japan, the United States and Europe have a fuel cell research and development program, China is also accelerating the process of fuel cell research, the development of fuel cells today nearly 200 years of history, which truly is a world wide attention in the 20th century, ThinkPad T42 Series,50's, from today, but also about 50 years, but fuel cell technology development is rapid.


Power gap calls for a new power technology


Portable electronic products in the global popularity of the increasing appearance of their products as well as the function of small light to the battery has become increasingly complicated and new challenges, and in addition to laptops, mobile phones and digital cameras, other products, there are also similar to the power supply gap . Existing rechargeable battery technology has matured, but the lithium-ion rechargeable battery capacity is not much room for improvement (less than 5% per year), in meeting growing energy demand will be much more difficult. But in the next few years is expected inside the existing battery technology will not be able to meet the growing portable electronics products of the energy demand,ThinkPad T43,new power technologies and products will be a huge market space and opportunities.


People's mobility more than ever before, and then expand the power of the gap. Notebook computer is the fastest growing areas, is expected shipments in 2006 to more than 50 million. Widespread adoption of Wi-Fi technology has actually cut off the shackles of Ethernet,ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193, and users will be the last hope is the path to remove the AC power cable, which is even more to promote a new battery technology.


The development of fuel cells


Because of its high energy conversion efficiency, clean and pollution-free, modular structural advantages and strong, fuel cells become the target of concern to the industry, to meet the immediate needs of the revolutionary power, fuel cells become a really strong player preparation. As early as 1839, ThinkPad R50,British scientists made W Grove on the principle of generating hydrogen and oxygen reaction, which is the first hydrogen fuel cell (FC) model. So far fuel cells mainly four kinds of types, they are as shown in table 1.

More than four kinds of fuel cells have their own characteristics,ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193, but also their different technical barriers and the development direction, but as a member of the fuel cell, they have the same general character, for which, combined with the characteristics of various types of batteries, fuel cells are summarized in the research and development should focus on several aspects.


Electrolyte membrane: H + only allows through, but did not break down the fuel does not allow infiltration of the past. Therefore, to study the electrolyte membrane including the proton conductivity of the electrolyte membrane, gas and other fuels to reduce the infiltration capacity, and enhance the redox and hydrolytic stability, improve the mechanical strength and thermal stability, in order to improve the surface properties and is suitable for catalyst combination. In addition, we must reduce costs and improve value for money.

Fuel: Study of fuel is the fuel of choice. At present, fuel cell applications, the main use of H 2 and CH 3 OH. Research on the replacement of fuel, fuel cells will enable the development of more sustainable.


System Architecture: System structure of the final results of the fuel cell. Because of the small fuel cell or micro fuel cell will be used in conjunction with the integrated circuit, so the development of system architecture is limited. How to carry out high-density fuel cell assembly,ThinkPad T42 Series, ThinkPad T43, ThinkPad R50, ThinkPad R51 Series, FRU 08K8193, the realization of portable electronic devices in the application of fuel cells, has become one of research directions.

laptop Battery recycle

Battery recycle

Battery is generally cylindrical in shape with two terminals, one positive electrode and one negative electrode that conduct electricity along with a substance called electrolyte, that works on the electrodes, chemically and help convert into electrical energy. IBM Laptop Battery,There is a copper wire that connects the two electrodes. Materials that are used in batteries are carbon, alkaline, chlorine, lithium ion, lead, nickel, sodium, silicon, copper, etc.


Batteries are classified into two- Dry cells and wet cells. The wet cell batteries are also termed storage 02K6928, 02K6620, 02K7039battery ( VGP-BPS5) as they can be recharged as many times as possible. Batteries are also divided as rechargeable and non-rechargeable or disposable batteries. The second type is again termed as primary cells, used till the chemical that produce the electrical current supply is fully consumed, at which point the battery is not needed anymore. These types of batteries are used very commonly in ThinkPad Z61t,small and portable piece of equipments that drain low current.


The other type is rechargeable or in other words secondary cells that can be “refueled” even after being completely consumed. For recharging, these batteries need some external help from devices as chargers or re-chargers.


In the present world due to the development of science and technology almost everything (papers, plastics, b, FRU 92P1167, ThinkPad Z60t, ThinkPad Z61t,atteries, aluminum, etc.) can be recycled without wasting it by just throwing it after use. Thus we see that recycling is a procedure by which waste products are recovered for reusing, which is also known as waste management.


Laptop Battery recycling falls under electronic waste or e-waste. Here any discarded, broken or unwanted electrical or electronic equipments, ThinkPad Z60t,containing toxic materials are recycled for further use. Batteries like, nickel-cadmium, lead, lithium batteries are made to reuse as the chemicals present in them can cause harm to the environment if allowed to stay long in open air after being discarded by the users. Moreover batteries are regarded as the most expensive energy source and their production requires much valuable recourse, so they are recycled so as to restore those valuable materials 02K6928, 02K6620, 02K7039
ThinkPad X60 from those old and used batteries through battery recyling.


Cadmium is a heavy metal and can cause pollution if burned or cremated. To avoid lead pollution lead-aced batteries are processed. This program is considered to be highly successful. Lithium-ion can be very dangerous if exposed to high temperature or sunlight, it can ignite or explode. 02K6928,Therefore battery recycling is a must if we want to protect our environment.


The Recycling Process:


First of all, the batteries to be recycled are sorted according to chemistries such as nickel-cadmium, FRU 92P1167,nickel-metal-hydride, lithium, alkaline etc. The combustible material, such as plastics and insulation, is then removed with a gas fired thermal oxidizer, which is the first step in the recycling process. Most recycling plants have scrubbers where the gases from the thermal oxidizer are neutralized to remove pollutants, producing clean, naked , FRU 92P1167, ThinkPad Z60t, ThinkPad Z61t,cells that contain precious metal content.


The metal in the inspiron 6400 batteries are then heated to liquefy, after they have been hacked into little pieces. Black slag left by burned out non-metallic substances are scraped off with a slag arm, and the different alloys that settle according to weight are skimmed off. Some plants pour the liquid metals directly into (65 pounds) or ‘hogs’ (2000 pounds) without separating on site, ThinkPad X60,which are then shipped to metal recovery plants to produce nickel, chromium and iron re-melt alloy for the manufacturing of other metal products.


State and Federal Regulations in the United States:

The Mercury-Containing and Rechargeable Battery Management Act was passed in 1996 by the U.S. Congress which requires regulated batteries such as Ni-CD batteries and sealed lead-acid batteries to:


1. be easily removable from consumer products to make it easier to recover them for recycling


2. include in the label the battery chemistry, the “three chasing arrows” symbol,02K7039 and a phrase that instructs users to properly recycle or dispose the battery


3. provide national uniformity in collection, storage, and transport


4. phase out the use of certain mercury-containing batteries


By recycling batteries the environment is not being polluted nearly as much, many natural resources are saved due to the rechargeable laitude d620 batteries also. 02K6620,There is a large variety of websites on the Internet with more quality information on recycling batteries.
