Notebook Our daily work and entertainment tools, with the continuous development of science and technology innovation, although from 1985, the first Toshiba notebook produced in Japan t1100 was born, but only 32 years, but all aspects of the notebook Profound changes, from the first laptop's "weight" to see, weighing 6.8 kilograms, and now the notebook has been well controlled within 1-3 kg, the earliest that laptop screen only 9 inches, 720KB hard drive, this Configuration now seems incredible, but as the first laptop to be the perfect combination of traditional desktop host and monitor, t1100 significant, lay the foundation for the development of modern notebooks.

The beginning of the birth of the notebook in order to meet the needs of people's mobile office, for now, this demand is the main reason for the purchase of modern notebook users, and the beginning of the notebook users are different, and now the notebook is relatively mature technology, the market is very More notebook models, the brand can be selected to meet different user needs, if it is game enthusiasts, graphics cards, memory and cooling to consider; even just want to buy a netbook, but also know what you choose notebook configuration, so as not to be Unscrupulous businesses cheat; some users go out for business trips often, under different environmental conditions, some laptop battery storage capacity is not good, so that there may be greatly reduced work efficiency

When selecting a notebook, the battery is one of the factors we have to consider, laptop battery capacity and service life is one measure of good or bad notebook.

So how to choose a laptop battery?

The main laptop battery to lithium batteries, nickel-metal hydride batteries and nickel-cadmium batteries mainly in the battery to the code that lithium batteries for lithium LI; said Ni-MH NI-MH; nickel-cadmium batteries that Ni-Cd NI-CD. Although the nickel-cadmium battery is the earliest used laptop battery, but because of its many shortcomings such as small capacity, toxic, pollution and other shortcomings have been eliminated, nickel-metal hydride batteries are the second generation of batteries because it does not contain toxic substances And the storage capacity is stronger, there are still some manufacturers in production, lithium battery is the third generation battery, although more expensive than the previous two generations, but lighter weight, larger capacity, no memory effect, the current Has been widely used, and now the market are basically laptop batteries are lithium batteries.

Special attention should be paid, how long the laptop battery can be used depends on the number of full charge and discharge, all rechargeable batteries are so, not to calculate the age, in normal use, the lithium-ion battery is about 400 times Put life expectancy, we bought a new computer first to recharge the battery with light, so you can save the battery charge and discharge times, and then is connected to the AC power to remove the battery, because most of the battery is designed to start below 95% Charging, prolonged incomplete charge and discharge will also reduce the battery life to a certain extent; In addition, the heat generated by the computer work will also affect the battery life.

If you do not have a long time battery, laptop battery should be placed in a dry and ventilated place, the temperature can be between 15 to 30 degrees, the battery best to keep a little power as well.
