To help you understand the laptop battery

With the notebook computer prices fall, presumably many of my friends have been eager for a notebook. We went shopping for notebooks, it is often to focus only on product price, weight, appearance and configuration, used by little to take care of notebook batteries.

In fact, the move tool for the notebook, the overall performance level of and inseparable from the merits of the battery, the battery is also no way inferior to the importance of CPU, motherboard, hard disk drives. The rest is with you to learn about laptop batteries, may be able to buy your notebook computer to make recommendations.

Let's start talking about the Dell 312-0273 battery materials, batteries currently used in notebook computers are three main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium Li.

In this regard the distinction between three types of batteries, I told a friend of notebooks sold had asked, he had also done phone sales, we'll hear how he said. "Laptop battery commonly used in our life there are many similarities between cell phone batteries, laptop and cell phones are the first use of Ni-Cd nickel-cadmium batteries, as battery technology was not advanced enough, so nickel-cadmium batteries have a lot of headaches disadvantages, such as: bulky, heavy weight, capacity, small, short life, there is memory effect, etc. (useless). the current nickel-cadmium batteries have been eliminated, notebooks, and nickel-cadmium must also, and mention it there is not much needed.

There are now battery-Li Lithium-Ion battery and Ni-MH Ni-MH two kinds, in which lithium has a small size, light weight, large capacity, low memory effect, charging time is short, etc., well received by customers love. " "I also like the lithium electricity, because it does not remember, when you do not have the first charge-discharge and convenient! The Earth people know that" On! "People think that there is no battery memory effect is wrong, this is misleading and irresponsible businesses.

Lithium batteries have the same memory effect, but its relatively low memory effect, but less obvious Bale. In addition, lithium batteries two types, one is a lithium battery, another is a lithium-ion batteries. " "What is the difference, how different?" "Lithium-Ion battery will have a long time ago, and it is not safe when used often in charge when burning, bursting, perhaps because of the sake of lithium element too active. Then there is an improved lithium-ion batteries, added element lithium can inhibit the active ingredients, so that lithium really a safe, efficient, convenient, while the older Lithium-Ion battery also will be eliminated. As to how to distinguish them from the battery's label will be able to identify, lithium as Li, lithium-ion battery for Li-ion.

Now, laptops and cell phones using the so-called lithium, in fact, lithium-ion battery. " "It's nickel-metal hydride batteries do?" "Ni-MH battery is the most environmentally friendly battery, pay attention to environmental protection, countries have been vigorously promoting the use of nickel-metal hydride batteries, because the ease of recycling, and the damage to the environment are minimal. However, nickel-metal hydride batteries and lithium compared, there are still some shortcomings . charging for a long time in weight than the sink capacity is also smaller than the lithium, as well as memory effect. Its Although these memories are not as big as nickel-cadmium batteries, but still need to discharge, the user must be exhausted before charging. laptop case, mobile phones are also the same. " Later, I also learned that lithium-ion battery (Li-ion more difficult to talk about, or called) also has shortcomings, such as charge and discharge times of high prices and less and so on. Lithium battery charging and discharging of the number of only 400-600 times, specially modified products, but many times 800. Charge once per day basis, the best lithium batteries, but more than two years of the Xiecai. And nickel-metal hydride rechargeable batteries for more than 700 times to achieve certain quality and a good product charge and discharge up to 1,200 times, so that a comparison, the nickel-metal hydride battery live longer than the lithium batteries and nickel-metal hydride batteries than the price of lithium batteries much lower.

View of this, there is no perfect laptop batteries. Know the laptop battery materials, let us understand their origin. Laptop battery origin is mainly Japan, South Korea, China and Taiwan Province of China, especially in Japan, mostly because the battery used in laptop batteries almost by Japanese manufacturers, such as: Toshiba, Panasonic, Sanyo, NEC and so on. While many brands laptop battery shapes, but the batteries used in these Japanese brands, manufacturing batteries for Japan's electronics companies have brought quite good gains. South Korea, China and Taiwan Province of China make more use of the main processing and production of batteries are also the core of Japan. Weight, shape and capacity The vast majority of laptop batteries to square, the market also has a small number of ultra-thin notebook using cylindrical batteries, such as the SONY 505 series, Toshiba PROTEGE series (I have not seen a triangle). The weight of the battery varies according to the material and models, to Toshiba 1750, for example, it is equipped with nickel-metal hydride batteries, the weight of more than 500 grams, I'll mention it hurt. I have seen in the market like a machine with the Toshiba 1750 is the same OEM manufacturer, the batteries are also common. But others are using a lithium battery, weighs less than 250 grams, so that I envy.

Mobile phone battery then compared the results of the same. So, I came to a conclusion, the same size and shape of the nickel-metal hydride and lithium electricity, double the weight difference. Volume size, mainly from the marked mAh battery to determine its Chinese name is mAh. Milliampere-hour size is directly related to the use of laptop time, I have seen the lowest laptop battery 3100mAh, the highest 4500mAh. According to common sense says, 4500mAh battery life much longer than the 3100mAh, but it can not be generalized.

Battery life notebook configurations with a great relationship, for example Well, the Dell 312-038 battery with a PIII-M, MOBILITY RADEON graphics cards and many other energy-saving technologies in hardware, with the 4000mAh battery, use of time up to 4 hours above. Using the Toshiba 1800 desktop CPU, although equipped with a 4500mAh battery, use of time can only reach 3 hours. This also indicates that the notebook battery mAh not only related to hardware, energy-saving technology is very important to choose the time needed to multi-reference notebook. How the price of laptop battery? Mentioned the importance of notebook batteries, notebook battery level of the overall performance of the pros and cons are inseparable, the importance of the battery is also no way inferior to CPU, motherboard, hard disk drives. Since the laptop battery is so important, the price naturally a lot of money.

As far as I understand it, the price of laptop batteries in the ? 1000 - ? 3000, accounting for the overall notebook price 10% - 15%, some ultra-thin models is even higher. In 1750, for example Toshiba: Toshiba 1750 is priced at ? 9988, while it uses nickel-metal hydride batteries should ? 1400. From this we can see, cost of the batteries has become an important factor constraining notebook price cuts. Compared with mobile phone, the laptop battery for less than the total price is too high, the price of mobile phone battery is generally the total price of more than 30%, to ? 1000 mobile phone, for example, the price of original equipment batteries around ? 300 also be regarded as a large child. Here, hot pepper advise you must treat the battery, whether it is laptop or cell phone. If this is because you used improperly, causing the battery OVER, regretted may be too late.

The manufacturer of the battery what kind of warranty? As we all know that the manufacturer's warranty on the notebook computer time is generally 1 year - 3 years. The time to enjoy the longest warranty in fact, only CPU, motherboard, memory, hard disk drive; fragile parts, such as: optical drive, LCD, shell, etc. can only enjoy one-year warranty; As for the battery Well, there is Paul 3 months , there is insurance for half a year, the longest, but also a year; there is simply not the battery out of the warranty, if the notebook to buy back home the next day the battery dies, you can only Zirendaomei. As market competition intensifies, the battery is not in the scope of the warranty is now rare.

However, the pepper, or would like to remind everyone to buy notebooks, make sure ask about the battery warranty period and conditions, be careful not much mistaken. Why is the battery warranty time so short? I have also asked this question a number of laptop dealers and manufacturers, and their answer is: laptop batteries are easily damaged goods, the frequency of recharging is a constant, with a little time, with Dehen something less than half a year reimbursed . Moreover, the notebook battery and other hardware different, there is no room can be repaired, only new ones, and the so-called warranty is actually a replacement. Products for such a long period of warranty (replacement), intangibles on the increased burden on manufacturers, as profit-makers for the purpose, who is not willing to Tam such a big risk.

It appears that right laptop battery 1 year manufacturer warranty is much mercy of the user. Genuine laptop battery warranty is the case, parallel imports can imagine and more. Merchants sell parallel imported goods have always avoided mentioning the warranty on the Dell 312-039 battery, users are rarely asked. Once a user referred to this sensitive issue, vendors are always batteries are generally not the problem, bad Baohuan so perfunctory.

I really can not think, have lost the regular support of parallel parts manufacturers, rely on the battery warranty? Is it then used to deceive users of counterfeit products.
