Many famouse brand laptop batteries recall
Toshiba has once again from Sony manufactured notebook batteries recalled. The defective Dell Inspiron 1525 battery can overheat and obviously the worst case, cause a fire in the.
The Japanese electronics company will share the world around 5100 lithium-ion DELL Latitude D820 Battery. This applies to all units that were produced in December 2005. According to Toshiba had captured in 2006 and 2007 because of the defective batteries three computers fire.
Already in September 2006 had approximately 340,000 Toshiba laptop batteries from Sony issues recall because of loading. Also, Dell and Apple then went nearly six million batteries because of fire danger from the Japanese manufacturer from the market.
The Japanese electronics giant Panasonic has, in Tokyo yesterday, Tuesday the recall of 6,000 notebook batteries for the Let’s Note CF-W4G “announced.
The affected batteries were the result of the company only sold in Japan information. As with the competition from Apple and Dell , which Dell Inspiron 1420 battery made by Sony have used, there is the defective devices, the risk of overheating.
The Dell Inspiron 6400 battery made by Matsushita were delivered in April and May last year. About the maker of lithium-ion Dell Inspiron 710m battery, is silent on the company. Matsushita has received so far indicated that the result still no reports of incidents with the affected batteries.

U.S. scientists develop sugar battery
Researchers at the Saint Louis University have a bio-fuel cell for mobile devices developed that converts sugar into energy using bacteria and thus provides the device with power. The cells are small enough to use in cell phones and MP3 players, according to the researchers. In addition, the system deliver enough energy to ensure a three-to four times longer life than conventional lithium-ion Dell Vostro 1510 battery.
"Our research shows that a renewable fuel can be used directly in the cell and operates at room temperature. This technology leads to a higher energy yield than is possible with metal-based approaches," said Shelly Minteer, head of the research team. "Our approach shows that the combination of biology and chemistry, the design allows for a better Dell Studio 1737 battery, which, moreover, is environmentally friendly." In bio-fuel cell produces carbon dioxide and water.
To demonstrate the correctness of their approach, the researchers built a prototype, which is about the size of a postage stamp. So they successfully operated a calculator and used it as a charger for a mobile phone. "If the new Dell Precision M6300 battery to our expectations and further testing is, could the commercialization in three to four years to be implemented," said Minteer.
Another advantage of the bio-Dell XPS M1730 battery is that it can run on virtually any sugar source, whether glucose, sweetened lemonade or tree sap. Were also tested carbonated beverages. Although this worked well, but the carbon dioxide could damage the fuel cell, Minteer says. Proved to be the optimal fuel dissolved in water table sugar.
Away from the end user, technology is of course interesting for military applications. The U.S. Defense Department is sponsor for Minteer studies.

Smart Lion extended battery test range
The Lion Smart GmbH, testers of lithium-ion batteries and developer of battery packs and battery management systems, its extended DELL Latitude D630 battery laboratory at the site near Munich Frieding to 180 square feet.
The company offers cell tests at 0 to 5 V and up to 10/120 now A module tests at 0 to 60 V and up to 200 A (up to 12 kW). The module tester also allow the use of 16 additional voltage sensors. LION Smart GmbH positions itself as a specialist for testing larger modules. Tests in conjunction with DELL Latitude D830 Battery-management systems are also possible. As part of the CIM program since 01.02.2010 Lion Smart is funded by the Federal Ministry of Economics and Technology to develop a DELL XPS M1530 battery management system.
The Lion Smart GmbH is a development services for research institutes, OEMs and suppliers to the automotive industry and other industries. As a spin-off of the TU Munich, the company operates test facilities and test laboratories for electrical storage.
In Brownstown (Michigan) the production of lithium-ion batteries for the Chevrolet Volt has begun. The new plant of General Motors subsidiary GM Manufacturing subsystem built this in just five months of construction.
Already in spring 2010 will ship the first Dell Studio 1737 battery to GM Detroit-Hamtramck, where the Volt will be built. Overall, GM is investing in the production of the Volt 700 million dollars (approximately € 490 million), distributed among eight sites. The electric car with range extender will be offered from the end of 2011, as Ampera in Europe.
In the pure current mode, the vehicle can travel about 60 kilometers. For longer distances, the model has an additional 1.4-liter gasoline engine that recharges the Dell Inspiron Mini 9 battery as a generator while driving, giving a maximum range of up to 500 kilometers.

New: Manufacturer statement about the temperature problem
Christoph Kaub, product manager for Latitude notebooks Dell”Latitude notebooks as a whole, certified and tested. This is what the certification before depending on model and configuration, a storage and operating temperature between -15 and +65 degrees Celsius. Depending on the type of Dell Inspiron 1501 battery has a life of 300 to 500 charging cycles (pro rata to understand on a full charge cycle). An explicit consideration of the impact have different ambient temperatures are not made there. ”
Fujitsu Siemens Computers”The running and a battery life may vary depending on system temperature and ambient temperature. For example, in Africa have a lower Dell Inspiron 1520 battery life than in Norway. Fujitsu Siemens Computers respects the design of the notebooks that the batteries are not heated or as little as possible from the system. A certain increase in temperature will not be reason alone to avoid, because the battery is in discharging warm myself. ”
Lenovo”At temperatures above 20 degrees Celsius, the capacity differences are not in a relevant area. And then there is at temperatures between 40 and 60 degrees Celsius almost no capacity differences. The temperature should be low, approximately around zero degrees Celsius, the capacity decreases by a few percentage points. Thus, the “normal” for operation of the notebook, such as DVD playback, resulting temperature has no significant impact on the “specified” run time and life of the Dell Vostro 1420 battery pack. ”
Dirk Lohmann, senior manager of service and support, Toshiba Germany”The technological descriptions in your article, we can confirm. Toshiba has taken into account when designing its laptops this framework. Therefore we can not confirm that the standard temperature values for batteries in Toshiba notebooks are exceeded, as long as they are operated at room temperature. Therefore we do not see it as necessary to issue a special use recommendation with regard to reduced battery life due to high temperatures during normal operation. Critical, we see the point of storage, for example in the car. This can occur very quickly due to sunlight or when stored below zero degrees in the trunk of damage to the Dell Latitude E4300 battery. ”
Conclusion: Most manufacturers downplay the problematic effects of high temperatures on the life and durability. Dell and Lenovo will see the negative effects of high temperatures up to 65/68 degrees Celsius on the life as not given. In contrast expresses Fujitsu Siemens that the run-and life will vary depending on the system and ambient temperature. Toshiba does not specify recommendations on use of life lost at high temperatures. As in the “normal mode” and use at room temperature, the conditions are met. The company admits, however, that, for example, sunlight or storage below zero degrees Celsius in the car battery damage occur.

Laptop Batteries: A disaster and its consequences
The lithium-ion battery is one of the most sensitive and most problematic components in a mobile device. It has a limited life and is extremely sensitive to extreme temperatures and mechanical stress. In addition, the charging and discharging of the energy donor is a process with very close tolerances.
Nonetheless, the lithium-ion Dell inspiron 1525 battery is one of the safest and most successful energy donors in the market. But the production process of the energy storage is very complicated and expensive, so that errors in production are low, but certainly occur. The recent recalls of various notebook manufacturers prove this. With Sony took over as a Dell Studio 1555 battery manufacturer’s exclusive responsibility.
After this disaster, some companies were worried about their reputation and image loss. So it is not surprising that now the Institute of Electrical and Electronics Engineers (IEEE), the standard guidelines for the design and manufacture of Dell Vostro 1310 battery revised. Our article summarizes the disaster with the lithium-ion batteries for Notebooks together.
If you are interested in the technological progress in batteries, you will find information in the article Current and future Dell Inspiron 5150 battery technologies. The security risks of lithium-ion batteries, the article illustrates batteries: Short-lived factory detail.

Li-ion batteries: the disadvantages
Li-Ion batteries are not standardized, but camera-specific. Even the Dell Inspiron 1525 batteryof the same camera producers are often not compatible. When purchasing a second battery that is for bigger trips or extended photo sessions generally useful, so you’re set on a particular Dell XPS M1330 battery model – and you can sometimes get to be extremely expensive – 50 euros or more will have to invest easily. For the price of some special Dell Latitude D630 battery, you often get two or three sets of good NiMH rechargeable batteries.
Also during the refueling of the Dell Inspiron 6400 battery you need because of the special connectors on the charger for the camera manufacturers. And we would like to make a further disadvantage of attention: If you need after two or three years for a defective DELL Studio 1537 battery replacement, this can be problematic. Possibly because the camera because of the short product cycles was taken long ago by the market, and a suitable replacement is not getting in regular trading.
