On the laptop battery — I have seen many articles, this is the most authoritative

There are now battery-Li Lithium-Ion battery and Ni-MH Ni-MH two kinds.

Lithium-Ion battery has a small size, light weight, large capacity,low memory effect, charging the advantages of a short time, a very welcome, but some people believe that there is no battery memory effect is wrong, acer 3260 battery it is irresponsible to mislead the merchants. Similarly, lithium batteries have memory effect, but its relatively low memory effect, but not very noticeable. If there is no memory effect, then, in many articles on the maintenance of laptop battery should be regularly referred to “full discharge”, “long useless to re-use to activate the battery” and other recommended Kai is not nonsense?

In a senior engineer I learned that in fact can be divided into two kinds of lithium batteries, 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 “”, 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, apple a1175 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 battery life of nothing but more than two years, so the laptop battery is the longest one-year warranty period is also the reason for this

Ni-MH battery is the most environmentally friendly battery, pay attention to environmental protection, countries have been vigorously promoting 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 batteries 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 apple a1185 battery 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 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 energy-saving technology the hardware and the use of P4 CPU, NVIDIA notebook graphics card, compared with the same capacity battery, the former use of time much longer than the latter.
