Notebook PCs have become a fashion, more and more people to give up the desktop, start selecting laptop computers. Not only on its portability has great advantages, make it a more integrated hardware footprint smaller. The
most important reason is the use of rechargeable laptop battery is one
of the advantages relative to the desktop, it can greatly facilitate a
variety of environments in the use of laptop computers. And with the progress of the battery level of technology, long battery life of notebook after another. Today, let's talk about the laptop battery that point thing.AC

We all know that as consumables, laptop battery life is. So select the notebook, an important factor is to see your beloved laptop battery is not easy to use. How to choose a laptop battery so it? This
problem should start with the basic battery from the laptop (hope that
we adhere to the reading, although some very dogmatic.)
1) There are several laptop battery
Batteries
used in notebook computers currently are three major types: 1.
Nickel-cadmium batteries, 2. Ni-MH battery, 3. Lithium battery; they are
generally expressed as: Nickel cadmium NI-CD, Ni-MH NI-MH, Lithium-Ion
battery LI.
2) the composition of lithium batteries used
Laptop battery by a shell, composed of circuit boards and batteries, are lithium-ion batteries. Generally they say the batteries means the number of batteries within the battery, mAh refers to the laptop battery capacity. Mainly
by the protection circuit board (or the secondary protection circuit),
and indicating circuit capacity of two parts, on the laptop laptop battery

charge and discharge and safety management.
3) Laptop battery life determinants
Laptop battery standby time determined mainly by the mAh value. In general, the more the batteries, mAh larger the longer standby time. Laptop
battery life is primarily measured by the charge and discharge times,
the quality of qualified products are generally 500-600 times. Therefore,
the effective use of laptop battery within a period of 2 years, after
which the battery will be aging, standby time of sharp decline in the
mobility of notebook computers.

4) Key: laptop purchase, how to see the battery parameters
Buy notebook, consumers tend to see is the parameter list and quotation. Among them, the parameters on the laptop battery only one or two. That is, is not lithium batteries and a few core. Tell you that the market is now the most common is the 6-cell ion battery. Normal life, in high-performance mode, up to 2 hours (except for those outside of BT laptop).
Understanding of the common, is that how we look at the battery parameters. In
a notebook battery can often be seen 4400mAh, 2200mAh nominal value
such as batteries, and I said just now is to determine the endurance mAh
key. I am sure there will be a lot of friends that the bigger the better mAh. But in fact not the case, the real master, a unit of battery capacity should be considered "Wh", its Chinese name "Wh." Of
course, "Wh" and the "mAh" is a close relationship with the following
formula: Wh ÷ V × 1000 = mAh should be noted that hp

electrical power consumption of the unit itself should be a power, that
is, "Watt."
