Types Of Laptop Battery
Types of laptop battery
Battery refers to chemical energy, solar energy, nuclear and other forms of energy into electrical energy. It is divided into a battery (commonly known as Dell Inspiron 8600 Battery cells) and the secondary battery (rechargeable battery can be repeated), as technology advances and the development of the battery through the photovoltaic cells from the initial to the nickel-cadmium batteries, nickel hydrogen batteries, lithium batteries ( including lithium batteries and lithium polymer batteries) and is developing fuel cells. Each technological innovation not only makes the battery capacity, weight, ease of use have a major breakthrough, but also becoming more environmentally friendly.
Notebook battery types and characteristics:
Nickel-cadmium batteries (Ni-Cd): It is used in notebook batteries in the veteran, but because it has a serious memory effect and anode materials used in Nickel (Ni) of toxic and cause pollution to the environment, so it is hang on a laptop soon be replaced by a more excellent Ni-MH battery.
Ni-MH Battery (Ni-MH): Nickel-cadmium batteries with the same structural principle, but will be replaced by the cathode performance better, more environmentally friendly non-toxic nickel – metal hydride materials. Although only a small change, but it brought great performance to improve. It also has a hard act to make the advantages of nickel-cadmium battery memory effect is not obvious, so that so that we no longer need to worry that nasty memory effect and thus more convenient to use. Although the performance of NiMH batteries is very good, but as technology advances it is lighter, higher energy density lithium batteries are replaced, become the laptop battery in the history of deadwood.
Lithium battery: Many people said that lithium batteries that we are now commonly used in lithium polymer batteries, lithium batteries, including lithium ion batteries in fact (Li-MO2) and lithium-polymer battery (Li-ion) of two. Because Li-MO2 battery market in 1989, when a premature explosion fire, so it quickly disappeared from view, replaced by safer lithium-polymer battery. It is light weight, in the case with the capacity of its Ni-MH battery weighs only about 1 / 2, so it quickly for mobile portable device’s new darling, Pitaiduoshuo notebook Diannao Suo Shi Yong, yes Xianzai Biji Ben battery Zhong’s backbone.
Fuel cell (Fuel Cell): Fuel cells are the future of laptop IBM ThinkPad T60 battery star, it has many types, including proton exchange membrane fuel cell (PEM), alkaline fuel cell (AFC) and solid oxide fuel cell (SOFC) and other However, as the fuel cell start-up time and operating temperature and other factors actually used for notebook computers only proton exchange membrane fuel cell fuel cell (PEM). PEM fuel cell using the fuel is methanol, the positive and the negative electrode, it is the principle of generation of hydrogen through the reforming of methanol after the negative input, positive input of oxygen through the catalyst, hydrogen atoms into protons and electrons, by the different paths into the cathode, e-cycle to produce electricity through an internal, proton through the electrolyte to the anode, when combined with oxygen to produce water and electrical and thermal. The experts agreed that restricting the commercial application of fuel cells the most important factor is the fuel cell to use the metal platinum (Pt) or platinum as the catalyst to the production cost has been high, the current production costs of fuel cells in the 500 to 1,000 USD / kW. Studies have shown that only when the production costs of fuel cells down to 50 dollars / kW level around can really accepted by consumers. The main reason for the high cost of fuel cells is not mass production, Once in production, the fuel cell’s information will certainly be greatly reduced.
The biggest advantage is the laptop mobility, provide the basis for all this is the battery. In the energy-saving technology and battery technology for the time being when there is no breakthrough, the full optimization of the battery and have some relevant tips will be helpful. However, long laptop battery life, it is often sufficient dissatisfaction and even damage the battery, and therefore must pay special attention to a number of techniques used.
First, choose the best time to repair
Laptop battery aging phenomenon is inevitable, almost all of the repair methods are trial “deep charge deep-release” principle, in order to ease the battery memory effect. Undeniably, however, the depth of the charge and discharge operation will not be good for the laptop battery itself is a method may not be at it. If battery life is only to reduce the tens of minutes, IBM ThinkPad R50 battery care should be taken to that method of operation. In addition, battery manufacturers have been optimized, there is no self-depth again to upgrade the battery charge and discharge capacity of the argument. But how when you need it is difficult to grasp the depth of discharge, after all, every time the electricity consumed is not the same, therefore we recommend using BatteryMon this professional software.
BatteryMon is a specifically for the small laptop battery monitoring software, especially for those without built-in power management chips and software for the machine, it certainly helped a lot of great help. BatteryMon most salient feature is able to discharge curve, and the installation will run automatically. A good performance will have a very regular battery discharge curve, as shown, is basically a grid of time each fall about the same. If found to have a very unusual beat, then it is necessary to carry out the battery “full of deep dark place” repair.
Second, “full of deep dark place,” the basic method
Battery calibration is an effective way to deal with aging batteries, in general, each brand will have a dedicated laptop battery calibration software. For example, IBM’s ThinkPad series have a dedicated discharge software is recommended for all users to use IBM notebook. But the process need to be repeated three times to get the best results. Download the software and the implementation of discharge, the system will be prompted to create installation disks. Use the installation disk boot PCDOS, unplug the AC power supply prompted the discharge control software will automatically discharge. When all the notebook will automatically shut down after, and then we can connect the AC power source for charging, time control in 9 to 12 hours, repeatedly 2 ~ 3 times.
Laptop battery for activation, we find the right key to discharge the software. Unfortunately, if your laptop is not specialized discharge software, it can be shut down in the BIOS and Windows power management features, then do not run any programs in case the battery Dell INSPIRON 9400 Battery out, then recharge in the boot state to about 80% was repeated several times such as after manual “full of deep dark place.” In fact, this approach aims to enable the continuous low current discharge batteries, which discharge state in our daily use is unlikely to be achieved, the effect of discharge and those dedicated basically the same software.
Software products on the laptop will affect the battery life in battery mode, the time issue has been somewhat controversial, but the problem now appeared to have no suspense, not only because of Microsoft’s operating system through the previous “ACPI driver BUG power” to the dispute already have results, but with Microsoft’s Windows Vista operating system, a large area of popular software products can shorten battery life of notebook computers have irrefutable conclusions.
Recently, a foreign media reported that as the Windows Vista operating system during the course want to turn the Aero Glass 3D user interface, indirect Or directly increase the notebook’s power capacity, said plainly, that the use of procedures as Aero Glass needs continuous system work to reflect, and then to CPU, graphics and display units such as continued heavy load of work, thus allow laptops require more power to meet the needs, and if the battery-powered model in the most direct result is a significant the shortened battery life, Vista “beautiful price” so.
In fact, from deployment to Vista on the notebook the day, its high power consumption has always been a concern, but now that concern consumers have been upgraded from general to many notebook computer manufacturers, such as HP and Lenovo and other well-known notebook manufacturers on this rather unhappy, we can see in the future, we focus on hardware energy efficiency in notebooks, while they should be from Microsoft software on the laptop to stop “tapping” the.
Microsoft’s operating system is recognized as the first big power Acer Aspire 1680 Battery the notebook platform, the “proposal” to optimize the improvements Microsoft have the same time, a more direct question is in the future, the number of software products will be a notebook computer Battery “life killer” or energy-saving notebook on the road, “stumbling block”!
