subject: Practical four steps to teach you buy a second laptop battery [print this page] Notebook computer battery is the "power source", especially for those who frequently walk my friends, In addition to selecting a selling point of the model have a very long standby, the timely preparation of the second block of the battery also an urgent task. Meanwhile, the laptop battery is also 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, Asus eee pc 701 battery the battery performance of the rapid decay and even examples of early retirement is not uncommon.However, unfortunately, in today's growing demand, the battery market is not followed by further specifications. Not only the renovation, the phenomenon of counterfeiting occurs when there is the original manufacturer, even in the same series There is also a man-made obstacles set up.And compared the election notebook, the battery did not to mention the choice easy!

A look at parameters
As the laptop battery's not universal, before consumers control of their own type of machine will accept batteries, at the same time to avoid being cheated, in the "look" link can not be relaxed work of check! In addition to individual low-end laptops now use nickel-metal hydride batteries, the most common use of all lithium-ion batteries, lithium polymer batteries only in part the use of high-grade ultra-thin notebook. Lithium batteries are generally set to protect the circuit and the capacity to monitor and communications circuit of several parts. From the perspective of parameters, the battery capacity is an indicator of concern. Now generally 3000 ~ 4500mAh, there are very few with 6000mAh capacity. Theoretically, higher the value, the same configuration used in the longer.
The manufacturers of the laptop battery has a more detailed description, we can often see the "six core 4400mAh", "4 core 2200mAh" battery nominal value such as the passage of time, we believe that directly determine the capacity of 4400mAh or 2200mAh laptop working hours.
In fact, when we talk about computer power consumption, the total nominal power use, rather than simply current. The battery voltage by the current power should be to the common 2200mAh, 3.6V batteries, for example, some small way may be formed by four batteries in series, the voltage is 14.4V, Capacity 2200mAh. More than many 14-inch notebook, you may use 2 and 4 strings of 8-core hybrid mode, the voltage is still to 14.4V, capacity doubled to 4400mAh, ensuring a longer duration of use. However, the same is 2200mAh, 3.6V batteries, if using 2 and 3 series of 6 core of a mixed mode, the battery capacity is still to 4400mAh, voltage drops to 10.8V, If you look at capacity, it should use the time and 8 the same core battery. If you press the power to count, 8-cell lithium battery, power should be 63.36Wh, 6 cores for 47.52Wh, 4 core for 31.68Wh. According to this value, 8-core advantage of lithium batteries can be reflected.
Appearance, the general assembly of the battery shell mold is not original battery standard, so when loaded laptop will appear to take difficult or loose loaded situation; assembly of the battery is not original battery plate production quality printing, writing rough and not clear, in any encounter when buying this kind of "original battery" do not buy. In addition, the renovation of the difference between products and new battery electrode wear also traces its gloss is not so heavy and new batteries, buy encountered the so-called "new batteries" do not buy.
On the whole, apart from "six core 4400mAh" this parameter, the battery voltage is also a need to know the parameters. From the application point of view, low-voltage large-capacity battery (and more parallel, less series) to ensure the notebook longer standby time, while the battery is almost no additional cost!
2 quality
Power quality is often directly proportional with the weight of the notebook battery is no exception. As the original battery protection circuit are doing more monitoring in place, the quality is better on batteries, so the weight of the assembly of the battery than the jerry-built much larger purchase Dian Dian hand, if the original laptop battery than the lighter, then Such batteries need to be careful! As the recent period, Dell, Apple, Sony, Lenovo laptop caught fire after another, making the image of the original battery greatly frustrated, but overall the quality of original battery or more outstanding. So I think that choice should be a second battery or original products. Of course, the market on the compatible battery has many types, implemented Gai's IC original brand notebook and high-quality electric core Shejizhizao, Bu Jin Suo You have the original battery's protection, as well steady performance and a fairly long time, actual performance is not much difference with the original battery; but some small workshop production of compatible batteries is not flattered by the quality of the battery's internal circuit design is extremely simple and the quality of batteries used more times, and some even use the disassemble or no-name batteries, battery compatible with the quality of this nature is not protected; In addition, some laptop batteries inside the original battery failure, a number of businesses by way since the batteries for the battery to get the original "new."
However, when this battery is not the true sense of the original battery, and it is compatible with the battery, its quality depends largely on how the quality of batteries. Therefore, Asus w3000 battery the compatible battery is worth buying, in addition to price, the key is to see how their quality. For those who come from a small workshop with a compatible battery, even if there is a great advantage in price, not worth buying.
Examples of laptop battery fire at home and abroad, mostly because the battery in use caused by overheating. In other words, the battery in the event of an exception, many times beyond the normal working state of heat distribution is a dangerous and can get us to capture source.Under normal circumstances, the battery generally showed only micro-heat it. Thus, in our test battery for a long time to be tested, touching the surface, if the feel hot or hot to illustrate the quality of the hidden dangers that exist within the battery, do not consider buying.
Dian weight, measured surface temperature may seem simple, but the safety of a battery has a very good role revealed.
3 Performance Measurement
Face to face in the computer market and businesses buy laptop battery, battery testing is an essential part. One focus of the test view charge cycles, the second is the standby time. Many people think that the useful life notebook battery is calculated according to life, it is not true, the real factors play a decisive role should be to fully charge and discharge times. Generally speaking, the international brand of notebook product line will be included in its software in the battery provides a management tool. This tool reads the battery pack through the intelligent control chip inside to see such as the use of time, the battery design capacity, actual capacity, and discharge times and other information. Through which users can understand some of the surface of the label in the battery can not see the information. Such as the Lenovo ThinkPad, SONY laptop batteries and some other management program can view the detailed battery information, if the original purchase of a new battery, battery charging should pay attention to whether the number of 0 (charge up to 2 to 3 times second, because some merchants also purchase the battery after the charge and discharge test).
Second is to check the battery capacity. The battery is fully charged capacity compared with the design capacity, if found to be less than fully charged capacity of the design capacity of many, the battery has a greater decline in performance is not recommended for purchase. If your laptop's battery management program does not have check the battery fully charged capacity options, such as software to detect with BatteryMon get.
In addition, the battery is compatible with the original battery there is a big price gap between, in order to prevent the compatible battery business to sell as the original battery in the battery management program should pay special attention to "producer" and "Part Number" followed by the contents of display . Original batteries are generally shown as SONY, SANYO, etc. the standard battery business name and part number, and compatible with the contents of the battery display is varied, such as PS or CMP, as well as IBM-COMPATIBLE or IBM-X3x so.
Of course, if conditions permit, it is best to have the intention to buy into the notebook battery is fully charged, to the Internet, DVD players and other operations. If the test half-way, the screen suddenly appear dark or irregular light suddenly flashing about, or (if BatteryMon) to monitor the battery discharge curve is not smooth, there is the phenomenon of power sags (for example, once from 70% to 6%) the battery power is not stable enough, it may be the quality of the internal batteries are not good enough, or the circuit design is not in place, such batteries should give up the purchase. If enough time, you can shop in the business has been tested, until the battery runs out, the final accounting of what the actual use of the battery time is in the normal range.
Should be pointed out that manufacturers of standby time is rated: battery power (WH) / notebook standby power consumption (W) = Standby time (h) the formula derived. Difficult to achieve because of physical tests required by the official standby power, so when the battery is not very different from the official when the gap between the nominal and the battery can not prove a problem!
Four questions about service
Laptop battery is also a goods and services the same can not be ignored, not to mention the price of the current laptop battery is still a lot of money!
From the perspective of the warranty, notebook computer battery is the shortest of all parts of the parts warranty, most warranty only 3 months to six months, or even were not in the list of warranty, battery warranty for up to one year less of Also less. Battery such treatment has not sold separately and improved, in general, new batteries (including compatible battery) can only have 3 months or 6 months warranty, if the battery is used, there will be about 7 days to 1 months warranty. Therefore, consumers in the payment be sure to ask before the battery warranty period and conditions, do not forget to ask for proof of purchase to the business (such as an invoice or a receipt stamped), and to indicate the battery warranty period for business.
Overall, the market supply of laptop batteries of various brand notebook main website and maintenance of points, laptop computers and online shops and other businesses. The official web site and brand notebook battery maintenance point of sale positive for the original goods, and users can also enjoy the regular service, Clevo d400 battery defects are generally higher price; computer most of the city business notebook batteries sold with the brand, the advantage of much cheaper price than the official website, inadequate quality of service vary widely, there is "Depot" was unauthorized, "for the core" phenomenon! In this event, Sony, Dell, Asustek Computer, manufacturer service centers that have the problem the whole laptop battery should be replaced, and should use the original batteries, regular service centers do not provide repair (ie change of the "core", activation, etc.) business. Battery recycling will be centrally, there is no "Depot Repair" one said. Thus, value services have to be regular vendors to buy!
Together, provide a replacement warranty business is most worthy of consideration!
