Handbook laptop batteries

Each laptop has a different battery based on manufacturing technology, but are capable of metabolic chemical energy into electric current

There are four battery manufacturing technology is being applied.

There are currently four battery manufacturing technology is being applied, but will soon have a new technology is put into practice to produce batteries capable of meeting the needs of different uses.

The battery is however different in manufacturing technology, but are likely to transfer chemical energy into electric current to run electronic devices - from a tiny music player to the big laptop. Like battery-rules for cars, chemical reactions inside the laptop battery release electrons, and this pushed the electrons move from the positive electrode to negative electrode, generating enough current to help your work dynamic.

In the early period, batteries used for mobile devices using energy cells made of compounds of Ni-ken - Cat-mi (NiCd). Battery is used for the laptop. NiCd cells, but only the capacity to store energy for operating system integrity integrity in an hour, and very harmful in the process of decomposition when not in use.

Today, cell lithium-ion (Li-on) with the ability area 2 times the power than the battery Ni-ken - Cat-mi, being widely used in most laptops, electronic devices portable, mobile. Lithium-ion batteries can store a large amount of electricity, but the materials and chemicals used for manufacturing batteries quite expensive. The success of lithium-ion battery also thanks to the controller chip attached to a control process "exhaust" power and avoid load "overload".

Meanwhile, Lithium-polymer battery (Li-poly) is used to model mobile phone, handheld devices and laptops advanced. Category is not only lightweight but also laminated, with the ability to approximate area power lithium-ion batteries.

Storage capability of battery power is limited, but with the introduction of fuel cell technology advanced, the laptop can work with just a few days at full load. Next-generation battery using chemicals such as methanol contained in the small block, distinct from the normal power supply. Like a small chemical plant, a wide variety of different fuel cells are used in spacecraft, testing all kinds of environmentally friendly power plants and small. NEC researchers are developing a fuel cell used for mobile devices with battery life up to 40 hours.

Fuel cells work on the principle of reverse electrolysis solution ... fuel cells stimulated reaction between hydrogen and oxygen to create electricity, Mr. Yoshimi Kubo, the direct management and supervision of U.S. fuel cell for laptop by NEC.

Methanol or methyl alcohol as fuel NEC selection. Kubo and his team have created laptops use a fuel cell can operate for 5 hours with about 0.5 liters of fuel (she dac10%). At the end, users will have to pour more fuel to prevent and contain cells ready Left "produced" electricity. So instead of battery reserve, the user will carry a bottle of methanol in the long journey, but very careful because methanol is toxic.

Currently, the most difficult problems is the "packaging" fuel cell. Replacing conventional position on my laptop does not fit the format of this cell. Will need the next steps to improve the laptop can use fuel cells, and size will also be a big obstacle. As well as his Kubo, NEC is addressing this issue in three directions: increase the density of methanol, using the processor to save power and prevent more contained larger.

This is a promising field will develop in the next decade, analysts Daniel Benjamin of the market-based Allied Business Intelligence in Oyster Bay, New York (USA) get to. According to him, fuel cells are a source of clean energy, but need to resolve the barriers of cost and technology. Daniel Benjamin is also expected, to 2011, there will be 200 million fuel cell with enough size and different capacity sold, used for MP3 player and laptop.

A name in the field of Japanese electronics, Hitachi Left direction using fuel cells devices smaller. In cooperation with manufacturers in the production of filtered cigarettes handheld devices using fuel cells. Size equivalent to the traditional AA batteries, fuel cells contains 57 grams of 20% methanol solution for laptops, can operate from 6 to 8 hours. Some sample was introduced to the public, one of which is MTI Micro positioning device GPS work in 60 hours. Chargers for electric fuel cells are Lilliputian research and production will soon be on the market in 2010.

By then, we can say "farewell" to the battery current. Song is a compatibility problem with electronic devices, and fuel used.

Duration of battery operation can be estimated for each laptop you buy.

Duration of battery operation can be estimated for each laptop that you choose. Processors often "consume" 50% of your electricity consumption. Recent improvements in chip manufacturing technology has improved comparatively in this limit. Platform processors like Intel Core 2 Duo and Core 2 extends the duration of the operation of the system.

The following sample processor power savings should be selected.

Intel Core 2 Duo up to save electricity. With dual-core processing capability and distribution flows, Intel Core 2 Duo balance between power consumption and performance of applications, extending the maximum duration of battery operation. Laptop use Core 2 Duo processor 2.53 GHz clock can increase battery life up to 4 hours.

Like Intel Core Solo Intel Core 2 Duo, but a single core processor. Therefore, the performance of the more limited but consume less power, 5.5 to 27 Watt compared to the 15-31 Watt's Core Duo. Core Solo processor with up to 1.83 GHz clock.

Intel Atom clock up to 1.66 GHz and L2 cache "modest" 512 KB. Intel Atom has been "change type" performance from smaller and more power saving, consumption of 2.5 - 8 Watt, used mainly for netbooks. Asus Eee PC is 1000HE example. With battery is up to 11 hours of operation with only one full load.

AMD Turion 64 X2 Ultra is a competitor of Intel Core 2 Duo. AMD Turion 64 X2 Ultra dual-core increase multitasking. Equipped with energy-saving technology that AMD PowerNow "ads" can be 'ordered long "duration of use of the system additional 65%. Maximum 2.4 GHz clock. Template convergence than a little more power than with competitors Core 2 Duo, about 32-35 Watt.

AMD Turion 64 is a version of "shortened" by Turion 64 X2 with full features, but like Intel Core Solo AMD Turion 64 is a single-core processors consume 25-35 Watt and clock up to 2, 4 GHz.
