New Lithium Battery Can Store And Deliver More Than Three Times Power Of Conventional Lithium Batteries.

University Of Waterloo has laid the groundwork for a lithium battery that can store and deliver more than three times the power of conventional lithium ion batteries.(gd761,kd476)

The research team of professor Linda Nazar, graduate student David Xiulei Ji and postdoctoral fellow Kyu Tae Lee are one of the first to demonstrate robust electrochemical performance for a lithium-sulphur battery. The finding is reported in the online issue of Nature Materials.Many laptop batteries are made of them,such as dell xps M1330 battery ,inspiron b120 battery ,

The prospect of lithium-sulphur batteries has tantalized chemists for two decades, and not just because successfully combining the two chemistries delivers much higher energy densities. Sulphur is cheaper than many other materials currently used in lithium batteries. It has always showed great promise as the ideal partner for a safe, low cost, long lasting rechargeable battery, exactly the kind of battery needed for energy storage and transportation in a low carbon emission energy economy.

“The difficult challenge was always the cathode, the part of the battery that stores and releases electrons in the charge and recharge cycles,” said Dr. Nazar. “To enable a reversible electrochemical reaction at high current rates, the electrically-active sulphur needs to remain in the most intimate contact with a conductor, such as carbon.”

The Canadian research team leap-frogged the performance of other carbon-sulphur combinations by tackling the contact issue at the nanoscale level. Although they say the same approach could be used with other materials, for their proof of concept study they chose a member of a highly structured and porous carbon family called mesoporous carbon. At the nanoscale level, this type of carbon has a very uniform pore diameter and pore volume.

Using a nanocasting method, the team assembled a structure of 6.5 nanometre thick carbon rods separated by empty three to four nanometre wide channels. Carbon microfibres spanning the empty channels kept the voids open and prevented collapse of the architecture.

Filling the tiny voids proved simple. Sulphur was heated and melted. Once in contact with the carbon, it was drawn or imbibed into the channels by capillary forces, where it solidified and shrunk to form sulphur nanofibres. Scanning electron microscope sections revealed that all the spaces were uniformly filled with sulphur, exposing an enormous surface area of the active element to carbon and driving the exceptional test results of the new battery.Dell inspiron E1505 battery ,latitude d830 battery .

“This composite material can supply up to nearly 80 percent of the theoretical capacity of sulphur, which is three times the energy density of lithium transition metal oxide cathodes, at reasonable rates with good cycling stability,” said Dr. Nazar.

What is more, the researchers say, the high capacity of the carbon to incorporate active material opens the door for similar “imbibed” composites that could have applications in many areas of materials science.The technology can be used in laptop battery area,in the future,we can buy better dell gd761 ,kd476 battery .

The research team continues to study the material to work out remaining challenges and refine the cathode’s architecture and performance.

Sony Announces Lithium Ion Secondary Battery – Last Longer, Recharges Faster

Sony. It’s yet another name when it comes to pioneering technologies that the world presumptively desires. We always wanted to get more juice from our battery powered devices even to the extent that we attempt to squeeze the last drop out.

Be it the mobile phone or the digital camera, it’s the human tendency to greedily wish that the battery lasted a minute more so that you could capture that candid moment or make the last corporate call before your battery is dead and wait for a recharge until you are back in your den.

Well, keeping in view the exploiting usage of battery charge by most of the devices, Sony has finally come up with a new type of rechargeable laptop battery – a Lithium Ion Secondary battery, that combines high-power and long-life performance, better than sony vgp-bps2c,vgp-bps2a ,vgp-bps5a battery,using olivine-type lithium iron phosphate as the cathode material.

Need More Power? Sony is here!

So, what is the new substance science that your Chemistry teacher didn’t tell you about? It’s Olivine-type lithium iron phosphate, the material used for cathode that makes the Sony Rechargeable sony laptop Battery so performing, so different.

Thanks to its robust crystal structure and consistent performance, even at high temperatures. This, in fusion with the Sony’s Particle Design Technology that minimizes the resistance to increase output, make a perfect combination to deliver interestingly good battery performance.

The best part about it. Each battery can take up to 2000 charge-discharge cycles and still keep powering your devices by retaining more than 80% of power redemption. Also, each battery will take not more than 30 minutes to charge up to a level of 99%.

For now, Sony has taken the initiative to develop these batteries only for motor based (power driven) tools for vgp-bps2c battery. Sony is planning to develop similar type of batteries for other mobile electronic devices in future, perhaps the ones that could replace our existing cell phone or digital camera batteries. And, the future is not that far.

There are no details on its pricing , scope of availability and rigid applicational fields yet. So, for now, click here to view detailed technical specifications from the Press Release.

Yesterday, my friend miss Yang took her HP DV2000 battery to my home and told me that her battery has died. She said that the battery can’t charge and she has changed a new battery, but still doesn’t work. It seems like a big problem, if the battery have problem, so we go to the repair store together.

We told all the information to the repairman Mr. Tan, he said that if you changed the hp laptop battery, then it proved the problem is not on the battery, and the laptop can work well, so the reason is only, that is the circuit on the laptop main board been damaged, so we have to unpack the laptop to check it.

Few minutes later, the laptop main board has been removed, you can see the position in below photo, this is the battery charge port, and if there is no external power supply connected, this is the power supply port of the battery.

To solve the problem should start at the charge port, check the battery pin has volt output or not, that is the right one highlighted in red circle in below photo, almost of the laptop supply 19V voltage to charge for the battery, then Mr. Tan test the charge pin with multimeter, the result showed the pin has no output voltage.

Since the charge pin has no output, then we to test the charging circuit of the pavilion dv2000 battery. Mr. Tan turned over the main board, so the component in the yellow circle is the charging circuit. This is a diode and FET (field-effect-tube), Mr. Tan tested the diode first, found one side has no voltage, so that’s mean the current has been cut before the diode, so next, we have to test the FET, the FET is a small 8 pin chip, and the FET also has no voltage. So the result showed the problem is not on diode and FET.

Mr. Tan tested the charging control chip finally, that is the component in the red circle on above photo. We tested that the current has not been enter into the FET, so there is big possibility of the charging chip has been damaged. After the test showed the problem is do like this, so the solving problem is quite simple, just change a same chip is okay.

Mr. Tan told us that there is no secret in this, and it is not caused by the wrong operation of user, as everybody knows that the hp battery(pavilion dv6000 battery,pavilion zv5000 battery) will generate big voltage when during each process of charge and discharge, pull in and put out will produce spark at the port, so this is easy to damage the battery or laptop main board, sometimes, after the laptop use for a long time, pull in and pull out the battery regularly will cause the problem of battery can’t charge, meanwhile, the quality of main board component is also important, take this laptop as an example, under normal condition, the big current during charging will damage the diode which at the end of the main board power supply circuit, but this laptop fired the power supply chip, obviously, the malfunction phenomenon is same, but the repair cost has been upgraded.

In the midst of a global recession, businesses struggle to find the value in buying powerful new computers. It is a situation that continues to prove torturous for Dell and seems to have paralyzed parts of the company’s turnaround efforts.

Dell, based in Round Rock, Tex., depends on selling computers to businesses and government bodies more than any of the other major computer makers. About three-quarters of its products go to such customers and dell laptop battery, while consumers make up the remainder. As businesses appear to be recovering more slowly than consumers, Dell is looking quite far ahead to find signs of optimism in the PC industry.

“We are preparing for what we believe will be a powerful replacement cycle,” said Michael S. Dell, the company’s founder and chief executive, during a conference call on Thursday to discuss the company’s first-quarter results. Mr. Dell expects sales to pick up in 2010, when customers may buy new computers to run Microsoft’s next operating system, Windows 7.

For now, Dell continues to struggle. In its first quarter, ended May 1, net income fell 63 percent, to $290 million, or 15 cents a share, from $784 million, or 38 cents a share, in the same period last year. Excluding restructuring and real estate charges, Dell earned 24 cents a share, beating analysts’ estimates by a penny.

The company, however, missed the analysts’ forecast on revenue. It fell 23 percent, to $12.34 billion, from $16.08 billion last year.

Revenue in all of Dell’s major businesses tumbled, including a 34 percent fall in desktop PC sales and a 20 percent drop in notebook PC sales(dell inspiron b120 battery ,inspiron b130 battery).

Dell has spent years trying to lessen its dependence on PCs by shifting its product mix toward data center equipment like server computers and storage systems. It has also tried to bolster its services segments and expand its consumer business. The company has long talked about making acquisitions, but it has sat on the sidelines during the recession and declined to make a major move.

Mr. Dell said the time to strike might be close. “Asset prices are getting pretty attractive,” he said on the conference call. “Certainly, we are looking at how we will expand inorganically. HD438 ,KD186 Battery”

Analysts contend that Dell’s options may dwindle if the company fails to act soon. Oracle, for example, has snatched up Dell’s long-time rival Sun Microsystems, and Hewlett-Packard bought the services giant Electronic Data Systems last year.

“Their targets are limited,” said Ashok Kumar, an analyst with Collins Stewart. “Eventually, Dell will have to step up their services profile, and the candidates are few and far between.” Dell had $9.7 billion in cash at the end of its first quarter.

But it has less buying power with its stock. Dell’s shares hit a 52-week high of $25.63 in August and have since dipped as low as $8. Shares of Dell closed up more than 3 percent on Thursday, at $11.48. After the release of the first-quarter results, Dell’s shares rose above $11.60 in after-hours trading.

While talking to financial analysts, Mr. Dell pointed repeatedly to the company’s recent cost-cutting measures. He stressed that Dell had focused on increasing its profits during the recession.

Dell’s operating expenses declined $312 million year over year. In addition, it produced $761 million in cash during the quarter.

The company acknowledges that its cost structure grew bloated in recent years, putting Dell at a disadvantage to Hewlett and Acer of Taiwan. Acer’s low costs have proved particularly beneficial during the downturn as its lower prices have helped it gain market share(acer aspire 3000 battery). According to technology analysts at Gartner, Acer is now tied with Dell as the second-largest PC maker in the world, trailing Hewlett.

Even if PC sales pick up in 2010 as Mr. Dell expects, the company could continue to find itself in a difficult position. “Dell cannot afford to go up against Acer’s low cost structure in the consumer market,” Mr. Kumar said. “And, on the corporate side, they have their work cut out for them as well because H.P is more of a one-stop shop for equipment.”

Dell Latitude D830 battery life time can be increased or decreased depending on the applications and tasks that you have your laptop doing. This article will tell you how to increase your Dell Latitude D830 battery life time.

Dell Latitude D830 battery life time can be increased or decreased depending on the applications and tasks that you have your laptop doing. For example, if you are playing a DVD movie, much power is being used, shorter time will your Dell Latitude D830 battery be used. If you are burning a CD-R/CD-RW or playing a full screen 3D video game, much power is being used. All these things take more power and in effect lessen the amount of time that you have in “portable” mode.
It is best to try to plug the laptop into the wall if possible in these situations. Remember that you can also get car power adapters for your laptop; this will charge your Dell Latitude D830 battery and power your laptop while you are on the road. Programs that take little power (giving you longer laptop battery life) include word processing programs like Microsoft Word or Corel Word Perfect, Microsoft Excel, Microsoft Access, Outlook Express, Internet Explorer, AOL, CompuServe, or any similar programs. Even the colors displayed on your screen can affect your Dell Latitude D830 battery life. Lighter colors take more power to produce. External connections such as USB Mice, USB Scanners, Memory Cards, Zip Drives, etc. all take more power from your precious Dell battery life. Keep these things in mind when power is of the essence.

Here are some tips to extend the life of your laptop battery:

1. Power down the display

Lowering the brightness may give you as much as an extra hour of runtime. And to increase even more the lifetime of your laptop battery lower the screen resolution and color depth. This will decrease the workload on the GPU, thus extending the battery runtime.

To change this settings follow the steps below:

2. Turn off unused devices

Many new notebooks provide a hard-wired On/Off switch for the Wi-Fi radio for this reason.
To save even more power go to the Control Panel, select System–>Hardware–>Device Manager, and disable the following items: Ethernet adapter, infrared transceiver, and Bluetooth radio . You should do this beacause having Bluetooth enabled and not using it actually consumes quite a bit of power.

3. Decrease hard drive activity

Defragmenting your hard drive regularly will decrease the frecuency with which your hard disk has to spin, therefore the dell inspiron E1505 battery will last longer. This is due to the fact that defragmentation optimizes the placement of the data on the drive and when a program makes a request for certain data it can be found more quickly.

To defragment your hard disk follow the steps in this article.

Another way to decrease hard drive activity is to set your paging file to a fix value, and this value should be around 1.5 times the amount the RAM you have installed on your computer.

To set the paging file go to the Control Panel and click through System -> Advanced -> Performance Settings -> Advanced -> Virtual Memory Change.

4. Disable startup items

Startup items are programs that load into memory every time Windows boots up and cause other open applications to spill over virtual memory and adds to the CPU load, shortening battery runtime. Here is how to remove some of them that are not necessary.

5. Condition the battery

Battery memory is where the dell inspiron b120 battery becomes conditioned to run for less time than it is designed to run. Say for example, you run your computer on latitude d830 battery for an hour and then you plug it back in to let it recharge. The battery will become conditioned to run only an hour before it runs out of juice.

To correct Battery Memory problems, you must completely drain the dell battery and recharge it. To completely drain your dell xps m1330 battery, you must go into your Windows Control Panel and select Power. Then you must turn Power Management Off. Next, you must go into your BIOS and make sure that if there is a power management setting there, that you turn it off as well. In most cases, once you are inside the BIOS, you will highlight Power Management and press Enter. Then locate the item Hibernation at Critical Battery, and by using the Minus sign, change the setting to Off. Once these steps have been completed, then use your Escape key to return to the top level menu, and select Save Settings and Exit.

Once you have completed turning off the power management in both the BIOS and the Operating System, you must unplug the computer, turn the computer on and let it run until it completely runs out of electricity. Then you should charge the battery for 12 hours. At the end of the charging cycle, then run the computer again until the inspiron e1505 battery is dead, and then charge the battery for 12 more hours. You should repeat this process four times, before returning the computer to its original power management settings.

A great little tip to keep in mind is that if you do keep your laptop plugged in for an extensive period of time REMOVE the battery. Let it discharge and give it a break. This will extend your battery life quite a bit.

Another way to condition your battery is to keep it cool. It’s best to use (and especially charge) your batteries at room temperatures. Extreme conditions can drain your battery quickly.

Hp Pavilion DV6000 series seems occered in a lot of problem. Some body says, The Pavillon HP laptops battery problems are truly the pits and may be enough for people to stop buying HP laptops! But I have to say that it’s not inherently HP’s responsibility, some problem of HP Pavilion DV6000 battery may cause by us and could be fixed by some simple operation.

HP Pavilion DV6000 Battery Problem Case

• When the Hp DV6000 battery powered, the screen flickers and finally crushes out.
• No matter when I use my battery to supply power for the laptop, the screen will suddenly flicker then die out when I using it. But the computer is still running and the screen still seems opened. Besides there nothing displayed on the screen (once I could watch movies and still hear sounds).
• This happens only when using dv6000 battery for power supply, and it is not the case when using AC power supply.
• I’ve got an HP dv6000 that will not charge the battery. I took the unit apart and replaced the power jack/usb board, thinking this would solve my problem…it didn’t. I am still having the same problem.
• I am able to charge the dv6000 battery in a friends hp and the laptop works great until I need to charge again.
• I noticed that my laptop power stayed at 6% even though I was on power for over two hours. I checked and noticed this…plugged in, not charging.
• My laptop is pluged on but the hp dv6000 battery meter keeps telling me that it’s not charging.
• Well…I have had the same problem with my DV6109. When the battery completely discharges due to lack of use and charging, it gets stuck at 0% and the red X appears across the hp laptop battery.

Basically, power down the laptop and then remove the AC adapter plug. Remove the dv2000 battery, perhaps wait a minute. Then put the battery back in and then plug in the AC adaptor plug. You then should see the charger light come on showing the battery is charging. Perhaps wait a few minutes before powering on the laptop to confirm that the battery is indeed charging. The problem seems to be in the logic (not sure where, if it is the software driver, etc.) when the laptop is on, it doesn’t get a charge. But with the laptop off, plugging in a battery after it has been removed – it works with a simpler charger system that doesn’t use the computers’s main CPU.

The problem is i shut it down fully charged. the next morning i star it up and it look ike it has been running as the pavilion dv6000 battery is down to almost half, i want to go away for a month and want to take it with me but cannot work on a half battery always. i enstalled the vista battery gadgets thingy, will that have an effect. when i shut it down it looks like there is some thing on still as a blue light stay blinking for a long time.

My laptop DV6500t turned itself on automatically after I shut it down. This caused the hp dv2000 battery to drain all the time. I sent it in for repair, but HP couldn’t reproduce the failure and just sent it back to me.

I have problem with my laptop, its 1y old, I bought it from a friend, and until now I didnt notice anything bad, because it was always plugged into power. Now what happens is , when i turn it on, w/o being connected to power, it boots up and when it reached windows screen, dv6000 battery goes to 0%. I’ve also noticed that when batt. is cca. at 65% (battery indicator), and not connected to power, its like when is at 0%, nb goes to sleep-mode , but when I try to ressurect it, it wont boot up. I have to plug it and then turn on. To my surprise battery is then indicated again at 0%.

Solution for HP Pavilion DV6000 Battery Not Charge

• Reinstalling the power management software has just fixed it for me. Go to device manager and under hp dv2000 batteries , unistall the Microsoft ACPI Compliant Control Method Battery. Go to Actions on the menu bar and select ’scan for hardware changes’. It will reinstall it and hopefully start charging immediately (mine did anyway).
• If your HP Pavillion dv6000 has a hp dv6000 battery that won’t charge yet still turns on when plugged in, turn off the laptop and remove the battery then wait for around 30 seconds, re-insert it and turn it back on, the charging update should say, plugged in, charging.
• I made the bios update, and works for me. My laptop battery problems were fixed. The battery led always blinking every time and the battery didn’t charge. Now it’s ok !
• If it is still under warranty you can chat with an online hp tech who will check it out over the internet and send you a replacement for free. the dv 6000 laptops have a recall on a few problems and there is a bios update to fix it before it happens but will not correct it after the fact the recall on specific problems extends the warranty to 24 months should get you to the warranty page.
• Just got it to charge again.While the laptop is powered and in Windows XP, press and hold the POWER button until it dies. Then, remove the dv6000 laptop battery. Power it back up and enter Windows. Then, re-insert the hp laptop battery.

So I always remove the Hp pavilion dv2000 battery after I have powered down the laptop, and I have not had any battery problems since then! I had the same issue my fix was a new cmos battery that was only $10.00 and install updated bios software from HP.I had the dv6000 battery problem where it showed my battery NOT CHARGING. I took it apart because my QUICKPLAY would not work either and the QUICKPLAY lights stayed on even after I shut down the laptop. I found that the black ribbon cable on the right (the other looks the same but you can see it is for the power button) was slightly kiltered in the flat socket it goes to underneath the area where the quickplay button is. I straightened it out and made sure it was pushed all the way in and locked and put it all back together and everything worked perfectly after that. About a month before that my POWER and SOUND didn`t work. I did the same thing to fix those problems. MAKE SURE YOU HAVE THOSE CABLES EXACTLY RIGHT in there, IT MAY JUST BE YOUR PROBLEM TOO.

Some people dont realise that you should avoid short charges and discharges, if your batery does not go above 40% mabe its charge memory thinks its full. to fix this problem let the batery run fully down, then charge it all the way again. try it a few times if it doesnt work. and you have to go all the way, not let windows go into hibernation. to do that you need to get the laptop battery low, then boot to some boot disk and let it sit till the batery dies.

HP has posted BIOS updates to address hp laptop battery problems as well as the auto startup on some.If you will post the full model number,someone can help you find your driver/updates page.

In general, the current lithium laptop battery pack itself with better protection.

It not only by the series / parallel connection of several batteries of the circuit itself also includes two substrate modules: the protection of the circuit substrate (Protection PCB) module and the Smart Battery Gauge Board module, and its set of battery design, including the first-class protection protection IC (to prevent dell laptop battery overcharge, over-release, short-circuit), the second-level protection IC (the second time to prevent over-voltage), fuse, LED instructions, such as temperature regulation components.

In the multi-level protection mechanism, even in the power charger, the computer result in an anomalous situation, the dell inspiron e1505 battery can only be converted to automatic protection status, if the situation is not serious, tend to re-plug in after the normal work can not explosion occurred. the face of the notebook battery explosion seriously the fact that journalists ask the power of professionals and a well-known manufacturers of design engineers.

According to analysis, lithium batteries from short circuit or explosion had sufficient cause, the greatest possibility is in the manufacture of lithium batteries, (dell gd761 ,dell kd476 ,dell td347)because of manufacturing process itself flawed, of products that may occur at any time there is a potential safety problems, such as should be insulation between the two poles of metal dust or copper foil and aluminum foil diaphragm perforation of the burr, resulting in micro-short circuits. The former situation is most serious, will be the direct result of a large number of short-circuit and heat production, resulting in vaporization of some of the electrolyte, the battery casing stretch.

In addition, there is a relatively special case, the power charger or computer due to special reasons, lithium batteries to provide instantaneous high-voltage / strong currents have resulted in a serious charge, such as the charging voltage by a sudden rise to 12.6V or 12.9V higher, then there will be a high-charge-flow generation, the internal battery charging circuits should be cut off the current action, but as some rechargeable lithium battery over-voltage, over-current protection design is very weak, which could result in damage to the battery protection IC,

So that the dell E1505 battery will not be harmed by the loss of protection, over-filling around the posterior pole piece on the crystallization of lithium metal needle, piercing a number of micro-point lead to short-circuit, causing the battery temperature gradually increased, until eventually the battery explosion, fire phenomenon, which notebook battery is a lot of “hot” factors.

Add a layer of protective cover

At present, the protection mechanisms from the point of view, the rechargeable battery pack in front of the traditional programs offered by the chip manufacturers are played most precise control of charging voltage and charge current role in the over-voltage and over-current control and did not provide the appropriate solution program. In this way, the protection of the battery pack is entirely dependent on the battery itself, such as over charge protection, over discharge protection, over-charge protection, over-current protection in place, over-temperature protection and so on.

Protection in place because of the need to prevent the first-level protection IC or MOSFET short-circuit fault caused by over-voltage fault, so the second-level protection IC will normally be considered is the battery pack to protect the last line of defense. In this regard, e-convex (O2 Micro) Product Manager洪仕vibration expressed different views, in his view, the protection of the battery pack can be moved forward through the charger attached to the control functions, to achieve the detection and control of inspiron 1501 battery charging action, which will undoubtedly further enhance the level of protection, the use of lithium batteries on the protection of security.

To this end, in the O2 Micro power management for portable devices developed by Cool Charge solution, the integration of a project called Cool Battery Technology battery protection technology, it is the most distinguishing features of traditional chargers generally do not have the OVP (over Voltage Protection) and OCP (Over Current Protection) functions to protect the two batteries, the technology has been embedded among the Cool Charge IC chip.

Cool Charge IC chip used, the power charger to a large extent to assume the responsibility to protect the battery. Subject to the control of the Cool Charge IC chargers, compared with the traditional design (see Figure 1), the need to significantly reduce the external device , Q3 and Q4 save a part of the design, reducing the failure rate. In Q1 retained and Q2 (components to improve the original design) between, Cool Charge IC set up a detection point, by default, the detection point

The voltage and current settings are set slightly smaller than the safety of the battery manufacturers specifications. In this way, the charging voltage or current beyond the Cool Charge IC security settings after the voltage or current, IC disconnect on the control of Q2, before the protective effect of the first battery to cut off the charge; from the detection frequency, the dell inspiron e1505 battery protection detection time interval in milliseconds level, and through the chip to detect, it can easily achieve the level of parts per million seconds, can be used for high frequency detection measured in order to achieve the first step in the protection of the purpose of battery pack.

Thin, large capacity, long service life, these are the outstanding characteristics of lithium. For this reason, lithium-ion battery to quickly replace the nickel-metal hydride, nickel cadmium batteries role as portable products such as notebook computer power optimization equipment life. And the near future, there is no new technology can replace the lithium battery power into the mainstream. we have to use the notebook in the usual attention to safety at any time, you can effectively avoid the occurrence of safety accidents.

Boston Power and Hewlett Packard have teamed together in the release of the latest green laptop battery . Learn more about the technology and the availability of a battery that is said to last for three years with no drop in performance.

New Enviro Series Notebook Battery

In their commitment to green computing, Hewlett Packard has developed a set of longer lasting batteries called the Enviro Series Notebook Battery through Boston Power. After a development term of three years, the batteries have been released on the open market for online purchase in early March 2009 with retail store purchase to begin at the end of the month.

The green ideal behind the Enviro comes from its longer lasting power capabilities. Use of the Enviro over the long term will cut down the need for notebook users to constantly upgrade to get greater sustainable power. The batteries also come with a three-year warranty and will fit eighteen of HP’s current laptops which include most Pavilion and HDX series computers.

Standard laptop batteries begin to lose performance after 100-150 charges, where the Enviro batteries claim the ability to be charged over 1,000 times and still offer the laptop user the same performance as when the battery was new. The base of the Enviro’s power lies within the use of Boston Power’s Sonata lithium-ion battery cells which is what enables the higher level of performance over an indefinite amount of usage.

Another difference in sustainability with the Enviro batteries comes from their manufacturing. Standard batteries(pavilion dv2000 battery , pavilion zv5000 battery ) are made from a combination of harmful environmental materials such as PVC and heavy metals all of which Boston Power has refused to implement in the batteries manufacturing.

Currently, this lithium ion hp laptop battery technology is the first to be both Nordic Ecolable and Chinese EPA certified based on stricter environmentally sustainable guidelines than that of the United States.

The Enviro currently retails for $149.99 which includes the three-year warranty. For more information on Boston Power’s developing projects and HP’s green technology distribution check out the following web sites: www.hp.com and www.boston-power.com

I am on the planes a decent amount of the time (100,000 miles by late May) and tend to spend a chunk of my flights using my laptop. Most of the time it’s productive, but it can also include a DVD or the occasional game (either Nethack or Battle for Middle-Earth 2, which are obviously similar). When I was a-hunting for a laptop, battery life was a key criterion in my selection process, as was weight. While I like my Vaio VGN SZ-160P, sony vgp-bps2c battery , the standard battery was lasting about 3 hours (the extended life clocks in under six hours before my tweaks), not enough for the SFO-JFK route (now switching to SFO-EWR as a default due to Manhattan traffic, which is a huge bummer because United’s P.S. flights have standard AC outlets on board).

So I did a lil’ Googlin’ for tips on extending battery life, and I found them all pretty, well, lacking. Stuff like “don’t try to do real-time 3d rendering” or “fully charge up your battery before flying.” One of them even said “buy an extra laptop battery .” Not exactly helpful (Sony’s tips are in the picture on the right). The most common tip that I’ve found truly deceptive is on disabling wireless: many claim it makes a huge impact to disable it, but personally I’ve only noticed a minor difference. I do in fact disable it (and Bluetooth) but on my Vaio the difference was about 10 minutes over 3 hours (but as I state below, it all adds up).

Alas, I’ve gone and done a lot of experimenting and have a list of my tips to really maximize battery life for my laptop.

Key to this process is having some good methodology. While testing, I kept a plain text file on my Desktop (creatively called “battery.txt”) tracking the real clock as well as Windows’ expected battery life. The problem with the Windows tool, is it really just tells you the current state of the battery based on the current system activity. This means if you start with 3 hours remaining then spend 30 minutes doing something that rapidly consumes the vgp-bps2c battery, you’ll be down to 2 or less. In other words, you need to track the actual history/lifespan of your battery if you want to get the best information out of your system. You can check out my little tracking file for inspiration.

Brightness: how low can you go? Without any question, the fastest way to suck the life out of a battery is leaving your brightness high. Turn it down as low as you possibly can without needing to up your glasses prescription. On my Vaio, I can select from one of 8 levels. During one test, at brightness level 3 my system reported 60% full, with 3:52 (all times are hours:minutes) of life to go. I switched up to level 5 and in 17 minutes of use, I was down to 52% full, with 3:06 to go. In other words, 17 minutes used 46 minutes worth of battery (all other variables were held constant). You can even be so bold as to lower your brightness all the way down when sitting idle for a minute or two (for example, if you are writing a long blog post and pause to clarify your thoughts before typing).

Don’t use any external devices. USB and PC-Cards (aka PC-MCIA) use your laptop battery to function, even when you aren’t using them! Have an EVDO card or maybe a USB mouse? Remove them if you can. Even a memory card reader in your PC-MCIA slot uses power just by being in there. The effect varies based on the type of device, but even a few minutes here and there (as you’ll see) add up significantly.

Single-task, not multi-task. The more you are doing at the same time with your PC, the more memory and CPU usage increases. Both of which directly use up battery. Close any applications you aren’t using, even the small ones. When doing some experimentation, I found it more efficient to run a single application at a time, then close it and open a new one when ready to move on. While your hard drive uses the battery too, if you are doing anything ‘productive’ you are probably hitting the drive on a regular (even if infrequent) basis anyway.

Keep it cool. You can take a page out of the extreme gamer’s handbooks, and have your system perform more optimally by keeping it cool. Make sure your air vents (inflow and outflow) aren’t blocked by anything, which often occurs by poorly positioning your notebook on your lap (which is known to have some other side-effects too, by the way). Heavy CPU and memory use all contribute to heat as well, hence my comment on multi-tasking above.

Shut down unused services. MSN Messenger, Google Desktop Search, QuickTime, wireless managers, etc. They’ve all gotta go. You probably aren’t going to use them, and they all eat up valuable resources. Especially things that ’scan’ anything. For advanced users, I also recommend launching Windows Task Manager and getting rid of anything not used in-flight. In fact, I put together another little text file with a list of all the services I don’t use, and I go down the list and manually shut down each one. If you really want to get this one right, a little bit of research is in order. While online, I launched the task manager (control-shift-escape) and for each service that has my User Name, I googled it. There are a few good web sites out there which chronicle what all these mysterious services do, and you should be able to figure out which you need, and which you don’t. Important warning: if you aren’t comfortable with this lingo, you should skip this step, or get some techie friend to help you out. Less important warning: you may end up in a situation where you need to do a reboot after you get to your destination.
Do Hibernate, Do Not Suspend. I’ve found that my Vaio tends to use way too much battery when in suspend mode. Not sure why, but the ‘instant-on’ effect isn’t worth the extra 30-60 seconds it takes to get out of hibernation. Furthermore, the minor hit to the hard drive is unlikely to have a significant impact to your overall vgp bps2c battery time. Also, if you weren’t aware, going in and out of hibernate is much better than a full startup/shutdown sequence. Note that you might need to manually enable Hibernate as a system option (once you have, the quick shortcut into it is ‘windows button’ followed by U followed by H, and some PCs will have even faster shortcuts available as well). If you make a run to the bathroom, however, that’s worth a quick Standby, but anything over 10 minutes and I’d Hibernate instead.

Tweak advanced settings. Virtually all laptops manufactured in the past 24 months have some advanced power options. Mine, for example, allows me to go into 16-bit color mode, force the CPU into a power-saving mode, disable my LAN port, and more. This might seem obvious, but if you aren’t doing it already, go find these settings (probably in the control panel, or possibly through custom software provided by your manufacturer) and get aggressive with them! If you don’t have any extra control, one good extra tip is to manually force your screen into lower color modes, as they use less CPU overall and can make a huge difference in the long run. While you are at it, you might want to change your Alarms settings, as many laptops default to shutting down with as much as 10% of your battery still available (my Low Battery is just an alert at 5%, and my Critical is force hibernate at 1%)!

Choose Wisely. Good: Word, Excel, Outlook, Text Editors. Bad: anything by Adobe (you think Microsoft has bloatware, have you noticed how long even Acrobat takes to launch these days???), all Google plugins, many ‘Widgets’, ‘Gadgets’, etc. All I can say is pick your battles wisely. 50 minutes of a video game ate up over 2 hours of my sony vgp bps2c battery time, whereas writing email or documents tend to use up less than what Windows predicts (about 105% of the estimate on average). I’ve also found WinDVD is right on the money for battery consumption, and Windows Media Player is a little power-hungry (by the way, if you are using your laptop to play music make certain you disable visualizations). On that note, don’t use your laptop to play music unless absolutely necessary, it’s a real resource killer.

Watch That Hard Drive. I just wrote, don’t play music, but the reason is mostly about your drive. The more it spins, the more power it takes. Make sure you’ve set your basic power option to turn off your drive relatively fast, but not necessarily too fast. Some drives use more power getting started than staying running for short periods of time. I set my Vaio to turn off the disk after 3 minutes of inactivity, you may want more, you may want less. At the end of the day, if you are doing anything that prevents the hard drive from spinning down ever, you are draining your battery more than needed.

Like a Boy Scout, Be Prepared. I make a point of configuring my ‘flight mode’ prior to getting on the plane. It may only take 5-10 minutes to get your system setup properly, but that just eats into your sony vgp bps2c battery life if you wait to do it on the plane. Once done with all the settings, the last thing I do before unplugging my power supply is hibernating the PC.

I hope some of these tips help you out. Personally, I add around 30 minutes (or more) to the longevity of my standard battery (3:30 on average now), and almost an hour on the extended one (6:30 or so). This gives me almost 10 hours of combined life (4 full DVDs guaranteed), which suits me quite well.
