1, the tendency to move
Internet matures has clearly begun to affect people’s lives. Development of the Internet and computers notebook is simply coincides with the birth. Notepad technological change and jumped on the applicability of laptops have a stronger impulse. In the mobile environment in the laptop and most tend to be practical and pragmatic.
Post-PC era, no longer troubled by the user is visible and tangible “hardware” products, but rather how to understand and better and faster access to information. Consequently, an increasing number of mobile computing tools focus on the critical need to address are: How easy and quick exchange of information, dell inspiron 6400 battery how to put these devices to connect more easily to the Internet, they can be as much time to maintain the original mobile characteristic of power without the constraints?
2, the source of the laptop computer
Slim, high capacity, long life, are the outstanding characteristics of lithium batteries. For this reason, lithium-ion, he quickly replaced nickel-metal hydride, batteries nickel cadmium role as laptops and other portable devices optimized for life. However, recent times, constantly being exposed exploding laptop battery makes notebook battery time and again pushed into a cusp
As of October 27, 2006, the overall number of Sony battery recalls again expanded to nearly eight million euros. Of these, 4.2 million Dell and Apple 1.8 million, 830,000 Toshiba, Lenovo 526,000, 287,000, Fujitsu, Hitachi, 16000.
Sony even greater concern is that this trend seems to recall continues to spread. Golden Week, in addition to Lenovo, the company has officially announced the recall of four numbers, sony vgp-bps8 battery there were companies such as Acer and Sony have also stated that he has been contacted to determine whether to recall their products.
For portable batteries overheating and even fire triggered the reason Sony has admitted that the existence of gaps in the manufacturing process. Short-circuit the battery, for producing a small amount of metal debris remain in the cell. Sony Rick Clancy, a spokesman said that in recent years Sony has been an increase in security measures, efforts to reduce scrap metal, but they can not be eliminated.
However, it is a laptop hidden built-in battery-known risks, charger or a laptop computer for various reasons, the instant of lithium batteries provide high voltage / high current leading to a serious overload, such as conversion the load voltage 220V to 20V or even lower when there is a high charging current generation, the battery must be in the circuit moves to cut the charging current, but because part of the lithium battery charging voltage, apple a1245 battery over current design of protective functions is low, which may lead to the battery protection IC is damaged, so as to protect the laptop battery so that the function of burning the motherboard is damaged, fire and so on and laptop given. Another laptop computers manufactured by working long hours on the high-temperature battery laptop has some influence! Because heat is the enemy of a battery, use of laptops would produce a certain temperature, which is very harmful for the battery.

Laptop battery on the market today can be divided into five categories: original laptop battery, the third brand of replacement batteries for the battery cell, an auxiliary battery, the battery of mobile external
In general, the best quality laptop original battery. If in earlier times through a series of tests, the more likely a problem, of course, original price batteries for laptops is relatively high.
Third replacement batteries party known as the OEM battery. In the cell production foundry both the strict replacement of some giant cells, but also black refurbished recycling of batteries used to do. The low price of these batteries are sometimes staggering. And because the poor quality of the battery problems are caused by many of the laptop on fire.
Zhongguancun, part of the electronics market, business laptop is very hot, and even sell cable network, and selling CDs to sell its reporters “service battery.” The “Battery Service” type of variety : Consumers may choose to “change the” kernel, or buying a battery, external battery, original batteries, used batteries, etc.;
Among them, the laptop batteries “kernel”, the most prosperous business. The introduction to business park in the heart of this change is to take the laptop battery actually open, which replaces the rechargeable battery. Merchants “For the kernel is very simple, very safe, for many people.” Some reporters. However, a journalist from the professional and technical information received, on the contrary “to the battery base is the most precarious. hp f4812a battery According to introduction, “to heart” very difficult to achieve after the laptop battery power requirements of laptops offers configuration, there is a big security risk. So, why people have chosen also for basic services?
The lack of attention to maintenance of batteries and battery problems inherent quality of these factors, a number of laptops are used for some time, the aging of the battery, wait times have significantly decreased or even unusable. At this stage, the replacement of their notebook batteries have become consumers faced with numerous problems. While consumers certainly comes to mind first is to buy original batteries, but a common brand of batteries original equipment often Yi Yuan in 2000, many consumers are left to think of a way Release.
Currently, royalties on the market for basic standards for a “core” (rechargeable battery) required about 50 yuan, according to a maximum of 9 “core” calculation, each battery for a laptop ” nucleus “is also up 450 yuan, and basically the price could be further to the” weak party talks. “As the name inexpensive, and many cases of” maintenance center “on the cover, which makes many consumers rush to this, the search costs of basic services efficient, there are ulterior motive.
To compete and sell so-called “original battery” Merchant said: “These” kernel “very” black heart “, many tenants are said to be” deposit “is that you bring to secretly “for the base. A merchant said: “Some merchants allow the user to see a good nucleus”, because it is defective, or even just for 12 ‘Base’. more ‘intelligent’ link ‘core’ does not change, but the old battery with high voltage-activated, as long as the user looks at the time of delivery can be used, they can receive money in A. But can take to use if they explode, so that the user or to buy us “safe home.”
Confirmation of this statement, the declarant to provide basic services to merchants for questioning, and some businesses were once tense, anxious to explain to basic services, no problem, saying that “to do, but we Insured not deceive you.
For basic services, can not be ensured, then the so-called “original battery” battery no problem? Or insider Inter-Business exposes so-called “original battery” especially the old laptop to “pull” down and rebuilt after the (such as “change the” kernel, etc.), and “foundry cell “” secondary battery “on or impossible to determine its origin in.
The external laptop battery is the new new thing. Small size, easy to carry. Using some time to enjoy the movable feast. External battery of the biggest advantages is its security, external laptop battery does not need help could be a load independent charging does not occur when the load caused by the excessive burning of the laptop. Also use a portable interface to supply external power supply, laptop computers are generally designed to protect the external interface of the power circuit, which makes the overall security has been greatly improved, also because it is external, dell gd761 battery the laptop to work long hours, the heat generated by an external battery that has no side effects, thus reducing significantly the incidence of failures and problems. Another external battery prices are much lower than the original battery, and has been a growing number of consumers.
Abstract:
Regarding the five types of batteries we use the following form to make a simple comparison (the highest five star).
Battery Original OEM battery used battery cell battery and external battery
Price High Low Low Low
Safety in High Low Low
Sustainability in the Low Low Low High
The failure rate is low, medium and high
Buy index ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★
5 types of cells, change the battery cell and secondary battery index buy the minimum laptop beloved, not defending the consumer to buy.
OEM Battery is the uneven level of participation time, too many variables and does not advise consumers to buy.
Original battery quality is better, but the price is high, if sufficient money to consumers, is a better choice.
External quality of the battery is good, price is not high, self-employment is also useful to my friends, is the best choice.
