How best to extend the battery life is of great concern to many laptop users do

Use rechargeable batteries for notebook computers is relatively one of the advantages the desktop, it can greatly facilitate the environment in a variety of laptop use. The current general use Laptop Battery is about 2-4 hours, if prolonged use of alternative power-saving features designed or prepared with a backup battery, can effectively extend battery life. Introduced the first battery is nickel-cadmium battery (NiCd), but this battery has a "memory effect", each charge must be discharged before, very easy to use, soon to be nickel-metal hydride battery (NiMH) are replaced, NiMH is not only not "memory effect", and the weight per unit can provide 10% more power. The most commonly used battery is lithium-ion battery (Li-Ion), it is no "memory effect" compared with NiMH, get laptop battery more weight per unit of electricity prices twice as high than the NiMH. Under the same weight, the three battery is 1:1.2:1.9 ratio.

Commonly used in notebook computers for civil battery can be divided into three types: nickel cadmium batteries (Ni-Cd), nickel metal hydride battery (Ni-MH) and lithium-ion battery (Li-Ion). Summary of their characteristics are as follows:

Nickel-cadmium batteries: nickel cadmium batteries used in notebook computers is the first battery types, as was the battery production technology, production technology is less advanced, so nickel-cadmium batteries have 很多 enough places, such as capacity Xiao, size large, etc.. Ni-Cd battery charge and discharge times of about 300-700 times, but in charge and discharge process if not handled properly, there will be "memory effect" (the so-called "memory effect" is the battery charge before the battery has not been completely exhausted, over time will cause the battery to reduce the rated capacity), making service life shortened. In addition, cadmium is toxic and therefore not conducive to nickel-cadmium batteries to protect the environment. Many shortcomings make nickel-cadmium batteries have been eliminated from the application of Notebook Computer batteries.

NiMH batteries: notebook battery type is the second generation nickel metal hydride batteries, nickel metal hydride battery Nickel-cadmium battery is relatively greater than the energy density means that no additional weight in the case, Ni-MH battery can be effectively extend the working hours of notebook computers. Ni-MH battery life is very long, can reach about 1,000 full release, Ni-MH battery Another advantage is greatly reduced in the presence of nickel cadmium battery "memory effect" problem, which makes Ni-MH battery can be more convenient to use .

Lithium-ion battery: Lithium-ion battery is light weight, large capacity, no memory effect, etc, and have been widely used - in the vast majority of laptops now use lithium-ion battery, although its price is relatively expensive. Lithium-ion batteries in laptop batteries in the current energy density of the highest, its capacity is the weight of the nickel-metal hydride batteries with 1.5 to 2 times, and has very low self-discharge rate. Lithium ion batteries have no "memory effect" and the advantages Dell Latitude c610 battery of non-toxic substances are widely used in notebook computers important reason. Although lithium-ion battery life is shorter than Ni-MH battery (usually about 400-800 times the number of charge and discharge), Dan Shi Ri Chang on its use Zhuangtaieryan, perform and NiMH batteries as lithium-ion battery, so Da Jia should try to choose lithium laptop.

How best to extend the battery life is of great concern to many laptop users do. Use some techniques and the use of small

To minimize unnecessary waste can make the most of your battery fully utilized, IBM Personal Computing Division to the vast number of engineers here

Laptop users offers some good suggestions to ensure the extension of books you can maximize battery life, thus enhancing

For efficiency, mobile office and entertainment to enjoy the fun without limits.

* To reduce the brightness of the screen. And while IBM Thinkpad Notebook computers equipped with a keyboard light ThinkLight, but in order to power, the best

Only under the conditions in the dark only to enjoy her care.

* When not using the wireless receiver device, turn it off.

* Some users love to open something all right CD or DVD to play music and the battery charge also play with the music to flow quietly away. Proposed large

Home only when you want to enjoy the music came alive again.

* Battery during charge and discharge completely as possible.

* Try to avoid very high or very low temperature use. For example, when you are on the beach when the sun, do not leave your books in the car steaming mulberry.

It was the battery for a laptop than the flow of blood, which, although not very appropriate, but the battery in the important position of notebook PCs is evident. Laptop attaches great importance to mobility, and thus the length of notebook battery life will become a measure of its mobility is an important factor in quality. If the loss of battery or poor battery performance, not only the mobility of notebook computers will be greatly reduced, its applications will subsequently be subject to certain restrictions. This article will guide you to understand what type of laptop batteries and enjoy its internal structure, will give full play to the battery DIY spirit of the restructuring, so as to achieve a better laptop for the purpose of our service.

Nickel-cadmium batteries: nickel cadmium battery is the first type of batteries used in notebook computers, but because the battery production technology, production technology not advanced enough, so a lot of nickel-cadmium battery deficiencies, such as the capacity of small and large size. Nickel-cadmium battery charge and discharge process if not handled properly, there will be "memory effect", so service life shortened. The so-called "memory effect" is the battery charge before the battery has not been completely exhausted, over time will cause the battery to reduce the rated capacity. Of course, we can control the charge and discharge reasonable way to reduce the "memory effect." In addition, cadmium is toxic and therefore not conducive to nickel-cadmium batteries to protect Dell latitude c640 battery the environment. Many shortcomings make nickel-cadmium batteries have been eliminated from the application of notebook computer batteries.

Since August this year, have had Apple, Lenovo, Toshiba and Dell announced the recall of several other manufacturers of notebook batteries manufactured by Sony, the reason is likely to lead to overheating and cause a fire. After preliminary judging, leading to immediate cause of the **** Sony battery cells in the production process of mixing metal particles inside the other with the notebook's system architecture and use of the environment there is a certain relationship.

Sony "battery door "**** is now a well-known, tens of millions of notebook batteries recalled the broad clear to the user, provide a Good Battery for notebook mobility, but also there is a threat to people health and safety impacts. We must ask: how can we enable consumers to buy the safety of the battery will not explode?

The importance of laptop battery

Notebook computer battery is the "power source" notebook is unique compared to desktop parts. It was with the battery, notebook was able to have good portability, and thus become an entertainment office in the right-hand man.

Life is a measure of the length of time a battery is a great factor, but also reflect the laptop is a good mobile performance an important factor. Today, people buy, the more concerned that the laptop's user friendly design, ease of use and operation of the degree of comfort performance. In particular, the length of battery life is also the focus of the content of many consumers.

Battery is a consumable, general use in 2012 will be significantly decreased after the performance, plus some users usually do not pay attention to battery maintenance work, the battery performance of the rapid decay and even examples of early retirement have occurred. Therefore, the re-purchase a laptop battery has been a priority.
