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.

Properly Charge Your Battery For Notebook PCs

Some lithium-ion batteries equipped with notebook computers,is depending on the use of smart battery systems such as the SBS technology to accurately measure the battery life, so use this like ThinkPadt40 Battery you don't need to worry anything. Although the lithium-ion battery has many advantages,to extend the battery life and maintain long time power supply, also need to master some professional charge method.

The new lithium-ion batteries bought in the initial use will be conducted three times a full charge and discharge, that is, fully charged battery at least once a power, then power exhausted, repeated three times before use. In order to activate the chemicals inside the battery, so that the electrochemical reaction inside the IBM 02K6488 battery into the best condition, in the future be able to freely use the charge that is useful, but to ensure that within one month, the battery must be a complete discharge, so that the depth of discharge can stimulate the activation of the battery performance, battery life plays a key role. If more than 3 months the battery is not used again before using the same should also be carried out with the new battery charge and discharge completely three times to ensure that activate the battery.

If you use nickel-metal hydride batteries, which must control the charge time, should be careful not to frequent over-charging, otherwise it will shorten the battery life. In addition, the Ni-MH battery should be fully discharged before charging, the charging should also be fully charged, and in normal use before, but also required to complete three complete charge and discharge times. Most users accustomed to using a laptop computer each time, plug the AC power supply, very little battery power for laptops. In fact, for at least a month should be used to power batteries once or twice, the IBM ASM 10L2158 battery completely run out, draw a line on a one-time full of alternating current. Remember this one, for rechargeable batteries will run out of power again full, useful and harmless, because the notebook computer lithium-ion batteries for use there is a certain inertia effect for a long time not to use lithium-ion loss of activity would need to re-activation. When the notebook computer when the indoor use of AC is best to remove the battery so that it always in charge state. The best off charging laptop, the battery can be fully charged, do not unplug the power in the charge half-way. Charging is completed, should be 30 minutes before use.

Has often been asked, "notebook computer battery standby time", which is a very difficult question to answer accurately, as previously described: the battery working time and its output current is related to current (at its maximum output current range) , then the working time is short. The notebook computer manufacturer not the same, brand, model different from the operating current is not the same. The same computer programs that run in their separate and different ways of working, such as when reading and writing is often hard disks, floppy disks, whether reading the CD-ROM, LCD screen brightness degree, resulting in operating current is very different. The most important thing is how to define "IBM ASM 10l2159", it seems to have no clear definition of uniform is the only operating system to run no other programs running? Or turn off the screen protection? Suspension CPU or system hibernation? Or other means, in short, "standby" in different ways, their work is not the same current, so the working hours or standby time is very different.
