Notebook emphasis on mobility, ibm thinkpad r50e battery is one of the key, the use of time has become increasingly the subject of attention, the author collected some information about this laptop battery information, and share with you
Let's start talking about the ibm thinkpad r51 battery materials, batteries used in notebook computers there have been three types: nickel-chromium batteries, nickel-metal hydride batteries, lithium batteries; they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium Li.
The first laptop is to use Ni-Cd nickel-cadmium ibm thinkpad r60 battery, nickel-cadmium batteries because it has many drawbacks, such as: bulky, heavy weight, capacity, small, short life, there are memory effect and so on. As well as nickel-cadmium batteries have been eliminated, does not make sense to discuss it, we all know what to do.
There are now battery-Li Lithium-Ion battery and Ni-MH Ni-MH two kinds.
� In fact, can be divided into two kinds of lithium toshiba pa3107u-1brs battery, a lithium electricity, the other is the lithium-ion batteries. Lithium-Ion battery in the early days there, but it is not safe when used often in charge when burning, bursting, it is because the lithium is too active reason. Then there is the improved version of the "lithium-ion batteries", which joined the element lithium can inhibit the active ingredients, so that lithium really achieve safe, efficient and convenient. While the old lithium battery and therefore eliminated. As to how to distinguish them from the battery's label will be able to identify, lithium battery for Li, lithium-ion battery for Li-ion. Now, laptops to use the so-called lithium, in fact, lithium-ion battery. Lithium-ion battery charge and discharge times in the 400-600 times, specially modified products, but many times 800.
If the charge once a day basis, the best lithium toshiba pa3356u-2brs battery life of nothing but more than two years, so the laptop battery warranty period is also the longest of the year because of this Ni-MH battery is the most environmentally friendly battery, pay attention to environmental protection, national have strongly advocated the use of nickel-metal hydride batteries, because the ease of recycling, and the damage to the environment are minimal. However, nickel-metal hydride batteries and lithium compared, there are still some disadvantages: charging for a long time in weight than the sink capacity than lithium is small, there is a strong memory effect. It is the memory, while not as big as nickel-cadmium batteries, but still need to discharge, the user must be exhausted before charging.
However, the number of Ni-MH rechargeable toshiba tecra 8100 battery can be achieved for more than 700 times, some good quality product charge and discharge up to 1,200 times, more so, and lithium-ion battery, Ni-MH battery live longer than the lithium batteries, but also the price of nickel-metal hydride batteries have is much lower than the lithium batteries. This is the nickel-metal hydride battery can be the reasons for market share corner bar.
Currently on the market, whether it is lithium-ion batteries or Ni-MH toshiba tecra a2 battery, its capacity sizes are based on mAh as a unit, its Chinese name is mAh. MA hours directly related to the size of the notebook usage time. But not the larger laptop battery the longer, which also linked to the notebook's components to decisions, such as: CPU, graphics card and so on, using the Centrino CPU, ATI-MOBILITY RADEON graphics cards and many other hardware and use of energy-saving technologies P4 CPU, NVIDIA notebook graphics card, compared with the same volume of electricity

IBM Thinkpad R60 Battery
We start our test with the new update Display.IBM Thinkpad R60 Battery FullHD The Color-Shine (Glare-type) display, such as Asus calls it, now offers a maximum resolution of 1920x1080 pixels. Compared to HD + display in the first variant of the G73JH that means the one hand to + on overview on the display, possible playback of HD content in native full-HD resolution - which also the integrated Blu-Ray drive really comes to coverage, and maximum possible image quality in computer games. This is already a criticism of the first equipment line would be cleared of G73JH. Lenovo r60 Battery What about now with the measured data of the new panels? Maximum we could in the central top of the display luminance of 197 measure cd / m². Compared to 241 cd / m² in HD + panel, this is still a clear step backwards. It goes further still: Even the average brightness of 183.85 cd / m² and the illumination of 87.5% are below the level of 1600x900er displays. Nine different models are currently listed with major price comparisons for the European market. From € 1599 may be located on the Intel i7 720QM quad-CPU and the 1920x1080 pixel full-HD display erfreuen.battery lenovo T61, or about € 200 more than the initial version with i5 CPU and less disk space and memory, and without Blu- Ray drive will cost. For the audience, of course, that raises a legitimate question: ibm ThinkPad T42 battery Is it worth the extra cost in terms of performance and image quality? We have tested the current model and try to give answers to these questions. Aspects which affect the unit's port facilities as well as the input devices will be left out. Detailed information can be found in our test of identical Asus G73JH-TY042V. Most of the pictures in this report comes just as the previous test.
