We all know that laptops hp Laptop Battery
We all know that laptops hp Laptop Battery can come out of what is a dark cell, and also know that laptop batteries are lithium batteries. History Why a lithium battery and discard the other?
The development of batteries for electronic productsibm Laptop Battery, the core material of power; very early that we did not say, was brilliant from the moment of the nickel-metal hydride batteries get started, a lot of friends in mainland China is also starting from contact with nickel-metal hydride batteries batteries. In the early mobile phones and other electronic products, Ni-MH battery is the main source of energy, of course, the notebook is also large quantities of early use of nickel-metal hydride batteries. ,
Speaking of nickel-hydrogen battery, a nickel and hydrogen should be a composite charge material, the use of such products produced by batteries, in fact, appear to be very perfect, environmental, safety, continuing a good time, so this kind of mass-produced batteries with lithium batteries now as popular in the world.
But over time, the power consumption of notebook itself is also increasing, Ni-MH battery was beginning to reveal the biggest drawback: the capacity balance between the volume-weight ratio, thin and light notebook and high continuation of some of the notebook, with a large block of nickel required MH battery to ensure that working hours.
Therefore, lithium also emerged, and lithium many shortcomings, lithium is a very active element, at high temperatures can easily cause an explosion, but the lithium battery makes it very exciting to have a characteristic is the same size the weight of the battery capacity than NiMH batteries to be several times higher .
People began to study lithium batteries, lithium batteries are not added to the active element and the shortcomings of lithium, so slowly as can be seen everywhere today, lithium batteries.
Because many of them started by NiMH battery contacts, the first impression and learn to judge what we do will always be a great standard. Ni-MH battery, we are close to remember the basic point: is the use of batteries to be completely, totally exhausted, and then fully charged, this is the decision characteristics of nickel-hydrogen batteries. NiMH batteries have no memory feature, if every time when using a re-charge Ni-MH battery capacity will reduce use. This is something many people have taken to the lithium batteries Compaq Pavilion dv4200 battery Compaq Presario V2300 Series battery.
That the use of lithium batteries should be fully charge and discharge each time point, is not, and lithium own characteristics with different Ni-MH battery, each time the depth of discharge, but will accelerate the aging of lithium batteries, lithium, therefore, when we use the final Do not wait to own less standby capacity. About 10% as far as the replacement or start charging a second battery. This is in the back of the battery maintenance, we have introduced.
The type and characteristics of the battery
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 brings great performance increase. 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 HP F4812A battery HP PF723A battery .
Lithium Battery: Li-ion battery is a lot of people that say 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) are 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 of the same capacity Ni-MH battery it weighs only 1 / 2 or so, it quickly became the new darling of mobile portable devices, used by most notebook computers, is now the backbone of notebook batteries.
