About the Laptop-Battery Danger

Apple Computer announces it is recalling nearly 2 million notebook computer batteries that could overheat and catch fire. The batteries, like 4 million recalled by Dell, are made by the same supplier, Sony.For personal, noncommercial use only. See Terms of Use. For other uses, prior permission required.

The Apple Computer company is recalling nearly two million laptop batteries like Apple A1008 because of a fire hazard. The move comes just over a week after rival computer-maker Dell announced its own battery recall. Both companies used batteries manufactured by the Sony Corporation.

Apple’s recall of 1.8 million laptop batteries is the second biggest ever for a computer maker, topped only by Dell’s Dell GK479 last week that it would replace more than four million batteries.

Mr. SCOTT WOLFSON (Spokesman, Consumer Product Safety Commission): We have the same issue once again of overheating, of that fire hazard. So once again, consumers need to pay attention to this recall.HORSLEY: Sony spokesman, Rick Clancy, says the battery cells involved in both recalls were made at the same Sony factory in Japan. Sony also makes batteries Acer Travelmate C300 battery for other PC makers, but Clancy does not expect any more recalls.
According to the Consumer Product Safety Commission, batteries in at least six Dell laptops overheated or caught fire, causing some damage. The Commission’s Scott Wolfson said Apple heard complaints from nine customers,likePowerBook G4 15 battery, two of whom suffered minor burns. Professor Sadoway has been looking for a way to build safer lithium ion cells by replacing the volatile liquid center with a solid. Even though such research is important, he says, it’s not been terribly fashionable.

Today, I made such a topic about that notebook computer users in the use, maintenance, and repairment could sum up some experiences to exchange for better management of their laptop batteries .

  1. the regular production of laptop battery manufacturers a variety of parameters clearly marked.
  2. buy laptop battery, the best choice nickel-metal hydride batteries or lithium-ion battery.
  3. genuine batteries commonly used PC or PVC shell material is very strong, difficult to damage, the general means can not open the laptop battery.
  4. neat appearance, there is no extra burr, a certain degree of roughness of the outer surface, and feel comfortable.
  5. notebook battery into the battery slot should be around freely, and closely integrated with the machine, while attention to the battery nominal voltage and voltage to correspond to your notebook.
  6. to ensure that purchase of the laptop battery charge and discharge of its good performance.
  7. under normal circumstances the thinner laptop battery, capacity, the smaller the thicker the laptop battery capacity is also greater.
  8. choose the laptop batteries and adapters necessary to ask the dealer asked in detail about the characteristics of batteries and adapters.

If you want to extend notebook battery life, we must also carry out proper maintenance of batteries and maintenance, the following is Ikunori maintenance and maintenance of notes:

  1. to avoid laptop battery at a temperature higher than 60 ℃ or lower than -20 ℃ environment, otherwise the use of time and life will be shortened. Laptop battery charging basic method, because laptop battery characteristics vary, so it must be in accordance with manufacturers instructions manual method of charging.
  2. if not a long time the machine is best to remove the laptop battery because the case does not boot, will be a gradual loss of laptop battery power
  3. due to a general non-rechargeable batteries, lithium batteries, such as the forced charging will cause an explosion.
  4. do not laptop batteries and some metal products together to prevent such metal objects touch the battery polarity, short circuit caused by the phenomenon.
  5. laptop battery when not in use, if temporarily, you can temporarily release some of them power, but then save it.
  6. due to its chemical properties of lithium-ion battery is extremely active in response to intense, so we should not arbitrarily to its demolition. If rain, moisture, dry cloth can be dry, put in dry and ventilated place on their own or with hot air drying of about 40 degrees.

The best way to buy is to look up the manufacture of your laptop and input the laptop model into the website and then select a higher cell dell inspiron E1505 battery. You can also buy an extended battery from them as well. So if you have a Dell laptop then you would want to go to www.Dell.com and type in battery replacement along with your code as in Dell GD761,KD476 .and it will display the different batteries that you can buy. You can use this technique for all laptop brands on the websites.

Step 2If you don’t want to buy a better battery than you can make some changes to your settings on your laptop that will increase the battery life.

Step 3This is for Vista users

Click on start/control panel/Mobile Pc/Power Options.

Here you can select how much power you want to save but the more power you save the slower your pc becomes. (Note)that if you change the settings to power save or balanced then when your laptop is plugged into a power outlet, your laptop will still be set to a slower performance.

Step 4: Click on High Performance and click on Change Plan Settings. This is the best setting because you can fully customize how much power you can save while running of your laptop but when you plug into a power outlet your laptop will return to the High Performance Setting.

Step 5: When the High Performance Setting window pops up then click on Change Advance Power Setting and then the Power Option window will popup.

Step 6:Power Option Settings:

Here you have full control over your battery settings.

Click and expand the Hard Disk tab.

Turn off hard disk after: On inspiron E1505 battery: You can set this to the desire time that you want. I have mine set to 30min//Plugged in: Again, you can set this to the desire time that you want. I have mine set to Never because plugged in I am not using my battery.

Step 7: Expand the wireless Adapter Settings:

Power Saving Mode:

On battery: Here you can select Maximum Performance or Maximum Power Saving. If you want your internet to still be fast then select Maximum Performance but if you want to save dell E1505 battery power and don’t mind a slower internet then select Maximum Power Saving. There are two more settings that you can select to have it a Medium Power Saving and Performance.

Plugged in: You will want this to stay on Maximum Performance.

Step 8: Expand the Sleep tab:

Sleep After:

On battery: Select the time which you want it to go into sleep mode while running on the battery. I have mine set to 15min

Plugged in: I have mine set to Never

Step 9: Expand the Processor Power Management tab:

Minimum processor state.

This is how fast your laptop will be when plugged in or running on the battery

On battery: Set it to 15%

Plugged in: set it to 100%

Now expand the Maximum processor state:

On battery: you can choose 20% to save on battery but if you need more speed when running the GD761 battery you will need to increase this number to around 50%

Plugged in: Set this to 100%

Step 10: Expand the Search and Indexing tab:

Power Saving Mode:

On battery: Set it to Power Saver

Plugged in: Set it to High Performance

Step 11: Expand the Display tab:

Turn off display after:

On battery: set it to 5min

Plugged in: you can set it to whatever you want. I have mine set to 20min

These setting will turn off your screen after the given time that you set.

Step 12: When you are done click on Apply at the bottom and then on OK

Step 13: You will be back to the Change Settings for the plan: High Performance window. On this page you can adjust the display brightness:

On battery: slide the bar to the left and it will dim the screen when it is running on the battery.

Plugged in: You can just leave the slide bar all the way to the right.

If you do not change the display brightness then your graphic card software will be monitoring it and you will need to launch the program to make the changes.

Step 14: When you are done click on Save Changes at the bottom and close out all open windows.

Step 15: Un-plug your power adapter and move your mouse toward the time in the right lower side of your screen at the taskbar and place your mouse cursor over the power option icon and it will display the life of the xps m1330 battery. Ignore the warning about your current plan may reduce battery life because you made the advance changes to your battery. With these new changes on my laptop with a 6 cell battery I am now getting 4 1/2 hours of battery life. Before I was only getting 2 hours of battery life. But this is only with my laptop yours may be different.

Step 16 : Also, the more programs that you run while using the battery will drain it faster so try not to run a lot of programs.

Step 17: Xp users

Click start/control panel and navigate to your power options.

Now I don’t have windows xp anymore but if you look around on all the tabs and look for advance options then you will be able to adjust the battery life to what you want it to.

Step 18: If you are not happy with the performance of your laptop with saving more laptop batteries life then go back and increase the processor number.

Battery Tips

Battery Tips If you find yourself with no electrical adapter or power source and need your battery to operate for as long as possible, take good care of your laptop battery and ensure that it will be ready to work properly and efficiently in the battery mode. The general tips are listed as follows:

  • 1.Turn off Wi-Fi and BlueTooth – Most laptops have shortcut keys to instantly disable wireless networking.
  • 2. Don’t play computer games, music or DVD movies – Multimedia activities drain laptop batteries.
  • 3. Disconnect all external devices like PC Card modems, Firewire, USB devices and optical drives. Use the notebook touchpad instead of an external mouse.
  • 4. Adjust your screen brightness – Dimming your display saves dell GD761 battery power.
  • 5. Tweak Windows Power Options – Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity.
  • 6. Decrease or mute the Laptop Speaker Volume.
  • 7. Turn off all scheduled tasks.
  • 8. Turn off Auto-save features in Microsoft Office and other applications.
  • 9. If your PC has a built-in wireless card, turn it off or disable it when not in use.
  • Looking for the longest battery life laptop? Actually, many factors affect the amount of time that a laptop battery can deliver power before it must be recharged. How to extend laptop battery life? Here are some more tips to improve your notebook’s battery life:

  • 1. If you do not use your laptop for extended periods of time (a week or more), dell kd476 ,remove the battery pack from the laptop.
  • 2. Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can’t create as much power.
  • 3. Make sure to plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector.
  • 4. If you have a nickel-metal hydride battery(inspiron b120 battery,inspiron b130 battery ), completely drain and recharge the battery once a month to maximize its capacity to hold a charge.
  • 5. Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.
  • 6. For laptops that work as Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.
  • New Lithium Battery Can Store And Deliver More

    Posted on August 31st, 2009 in battery tips | Comments Off

    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.
