Battery manufacturers go all out to prepare for a new generation of portable computers as represented laptop battery by mobile devices replace the traditional desktop PC era.

According to International Data Corporation's news, the emergence of a more thin and light laptop battery industry has brought prosperity. Some of the weight of just 1.2kg, is expected to in 2009 so far, they can replace the traditional computer in the United States.

The manufacturer to extend its product life at the same time, other portable devices, such as game consoles, music players, PDA and mobile phones will drive substantial growth in battery sales.

Analysts pointed out that the device will focus on mobility of the major manufacturers such as Sony, Sanyo, Panasonic, Toshiba, Motorola and LG Electronics as well as the two Presario 700 manufacturers of growing Chinese companies, such as the private battery maker BYD Company Limited a huge encouragement.

In the meantime, a growing demand for battery backup, which makes a new batch of parts manufacturers on the market come to the fore.

Research firm Gartner analyst Alan Brown said: "in improving the battery capacity has indeed been developed, but more is to improve, rather than a revolutionary change, and can not be seen as a breakthrough."

Most portable devices could not handle the use of lithium Presario 1800 battery technology, under normal circumstances, only a laptop battery usage time up to 6 hours, while the cell phone you can use a few days.

But those figures are used frequently in the user or the use of power features, such as watching DVD and increase the brightness of the screen, the drop was a lot.

The world's largest computer maker Dell's vice president of the Asian market, said David Schmook, the company always pay attention to the laptop battery life can be extended to new technologies. However, he added, change has not immediately appear.

"Our products are mainly used is the lithium electricity," he said: "The recent point of view, the core technology has not changed."

Clients include IBM, Taiwan's largest aftermarket battery manufacturers Jing Shan (BIT) Technology Co., Ltd. a global product manager, said Howard Tseng, a new type of lithium-polymer Presario 1200 battery just entering the market, probably more than typical lithium-ion extended for another 10 to 20% of the life.

Be held in Taipei, the world's second largest computer exhibition Computex last, Tseng said in his company's booth, this new type of lithium batteries than ordinary electricity prices higher than about 50%.

As a notebook computer battery backup the fast-growing market leader, BIT has recently begun to invest in developing in Germany, Japan, Canada and the United States market.

European operations head David Wu that its competitors, such as Hong Kong companies and EVO N620C Bo Li Battery Technology companies also hope the next one or two years time, the first to open the market.

While the BIT, Dell and other manufacturers continue to focus on lithium battery technology, but they also pay close attention to the update is still in the experimental phase of the fuel cells. The battery is installed in the car for more, the use of hydrogen or other fuels for energy, just to add fuel before needing to recharge.

Wu said the fuel cell model in a recent trade show, probably is the current four times a typical laptop battery, such as a large size book, but he added, the use of time up to a full day.

Brown said the win light in the development of Taiwan is probably equivalent to the volume CD-ROM of the fuel cells, Toshiba is also doing similar research and EVO N610C development, "price, size and filling of access remains problematic. Within five years, the fuel cell is not the best options. "
