Emphasis on notebook laptop battery is the key
We start talking about the battery materials, batteries used in notebook computers
there have been three types: nickel-cadmium batteries, nickel hydrogen batteries, lithium batteries; they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium Li.
The first is to use Ni-Cd notebook nickel-cadmium batteries, nickel-cadmium batteries because there are many disadvantages, such as: size, heavy weight, small capacity, short
dell kd476 battery life, a memory effect and so on. As well as nickel-cadmium batteries have been eliminated, there is no sense discussing it, we all know about it.
Now the batteries are Li lithium and Ni-MH Ni-MH two.
Lithium has a small size, light weight, large capacity, low memory effect, charging time is short, etc., a very welcome, but some people think that there is no memory effect Lithium is wrong, this is actually irresponsible businesses misleading. Lithium batteries have the same memory effect, but its relatively low memory effect, but not very noticeable. If there is no memory effect, so in many articles on the maintenance of laptop battery should be regularly referred to "full discharge", "long time no use to activate the battery to re-use" and suggested Kai is not nonsense
I understand that in a senior engineer, two types of lithium batteries in fact, one is lithium, the other is the lithium-ion batteries. Lithium alone in those early days, but not safe when used,
Apple a1175 battery often in charge when burning, burst, and this is because the sake of lithium element too active. Then there is the improved version of the "lithium-ion battery", the added element lithium can inhibit the active ingredients, so that the lithium really achieve a safe, efficient and convenient. The old and therefore out of lithium. As to how to distinguish them from the battery's label will be able to identify, lithium as Li, lithium-ion battery Li-ion. Now, the notebook is 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 800 times. If you charge a daily basis, the best lithium battery life expectancy, but more than two years, so the laptop battery's warranty is the longest of this year is also the reason
Ni-MH battery is the most environmentally friendly battery, pay attention to environmental protection, countries have vigorously promoting the use of nickel-metal hydride batteries, as easy to recycle, and damage to the environment are minimal. However, compared to nickel-metal hydride batteries and lithium, there are some drawbacks: long charge time, weight more sedate, small capacity than lithium, there is a strong memory effect. Its memory, while not as big nickel-cadmium batteries
Dell precision m70 battery , but still need to discharge, the user must be exhausted before recharging. However, the number of nickel-metal hydride rechargeable batteries to achieve 700 times or more, some of the good quality products, charge and discharge up to 1,200 times, so that comparison and lithium-ion battery, lithium battery live longer than nickel-metal hydride batteries, but also the price of nickel-hydrogen batteries much lower than the lithium batteries. This is the nickel-metal hydride battery can be the reason for the corner of the market.
