The first lesson notebook batteries and common usage
Notebook computers have become a kind of fashion nowadays, more and more people choose to quit desktops, notebook computer. Not only in its portability a big advantage, more integrated hardware to the space. Among them, one of the most important reason is that use rechargeable batteries are relatively desktop notebook computer, it can be one of the advantages of convenient greatly under the environment in the use of notebook computers. And with the battery technology level of progress, long life time notebook emerge in endlessly. Today, I will talk about the laptop batteries.
Everyone knows as consumables, laptop battery is life. So choose notebook, one of the important factors that you love notebook battery is better. So how to select notebook batteries? This problem from the most basic to the notebook batteries of (hope everybody adhere to read, although some very dogma).
1) laptop batteries have several
Currently the notebook computer batteries used mainly in three types: (1), (2) nickel chrome nimh batteries, lithium battery; 3. They usually expressed as: nickel cadmium NI – CD, nimh NI fd-mh, lithium electricity LI.
2) used in lithium batteries
Notebook batteries by shell, circuit and the core component, belongs to the lithium ion battery. Generally they say is the core of the quantity, the core cell mAh refers to the laptop battery capacity. Mainly by the protection circuit board (or secondary protection circuit), and the capacity of two parts, the instructions of circuit batteries charge-discharge and safety management.
3) laptop battery life ability of the deciding factor
Notebook batteries standby time determined mainly by mAh value. Normally, electricity, some more mAh values, standby time longer. Laptop battery life consists mainly of cycle count to measure, the quality of products are qualified for 500-600 times. Therefore, effective system for laptop batteries battery within two years, will be aging, standby time sharply and influence the mobility of notebook computers.

Battery parameters
4) key: when the choose and buy, how see laptop battery parameters
When the choose and buy, consumer often see notebook is parameter table and quotations. Among them, the laptop battery parameters on only one or two. That is, lithium batteries and is a few core. Tell everybody on market now, the most common is 6 core ion battery. Generally, the high 3000ibs in most mode, 2 hours (except those BT notebook).
A common understanding of what I say, battery parameters. The notebook batteries in 4400mAh can often be seen 2200mAh, etc, and numerical nominal battery mAh said just now is to determine the ability of key negroponte. So will certainly have a lot of friends think bigger and better. MAh But in fact not so, mastery of a unit of battery capacity should be “Wh,” the Chinese watts. Of course, “Wh” and “mAh” is the close relationship between the following formula: Wh รท V x 1000 = mAh should be pointed out that the consumption of electrical metrology units should itself is power, namely “watt.
The battery is an important parameter and voltage, ma and watts three components, we can learn to choose laptop battery should be paid attention to when the place is not “mAh” but “Wh” and voltage. From the Internet to find an example to explain the reason.
