<DIV id="result_box" dir="ltr">With the reduction in the prices of notebook computers, will have many of my friends have been eager for a notebook. We buy laptop often focus only on price, weight, appearance and configuration, very little concern to the use of laptop batteries. In fact, the mobile tool for the notebook, the overall performance and battery level of the pros and inseparable from, the importance of batteries is also no less CPU, motherboards, <A title="Sony VGP-BPS3 Laptop Battery" href="http://laptopsbatteries.us/sony-vgp-bps3-battery.htm">Sony VGP-BPS3 Battery</A> and so on. Next, the laser on and with you to understand the notebook battery, you may be able to purchase notebook computers for some suggestions. <BR>
<BR>
Materials and production <BR>
<BR>
Let's start with the material about the battery, the current laptop battery use of three main categories: 1. Ni-Cr battery, 2. Ni-MH battery, 3. Lithium batteries; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, lithium LI. <BR>
<BR>
Battery on the difference between the three, I told a friend of the notebook sales have been asked whether he had also done phone sales, we hear how he said. "Notebook battery life with our cell phone batteries used in a lot of similarities, the first notebook and mobile phone use NI-CD Ni-Cd batteries, as battery technology was not advanced, so have a lot of nickel-cadmium battery is headache shortcomings, such as: bulky, heavy weight, the capacity of small, short life, there are memory effect, etc. (useless). At present, nickel-cadmium batteries have been eliminated, the notebook is also nickel-cadmium break, and again it is not much need to. There are now battery LI Lithium electricity and Ni-MH NI-MH two, in which lithium has a small size, light weight, large capacity, low memory effect, short charging time, etc., is quite popular. " <BR>
<BR>
"I like lithium electricity, because it does not remember, do not charge when the first discharge, the convenience! Earth people know you!" <BR>
<BR>
"People think that there is no memory effect lithium batteries is wrong, it is irresponsible to mislead merchants. Lithium batteries have the same memory effect, but its relatively low memory effect, but just not so obvious. In addition, lithium batteries at two types of lithium electricity, the other is the lithium-ion batteries. " <BR>
<BR>
"What is the difference, how to distinguish between them?" <BR>
<BR>
"Lithium has a long time ago, and it is not safe when used often in charge when burning, burst, and this may be because the lithium-active elements because of too. Then there is the improved version of the lithium-ion batteries, adding the element lithium can inhibit the active ingredients, so that the real power of lithium to achieve a safe, efficient, convenient, and the old lithium also eliminated. As to how to distinguish them from the logo on the battery will be able to identify, lithium for LI, lithium-ion battery for LI-ION. Now, notebook and mobile phone use of the so-called lithium, lithium-ion battery is a matter of fact. " <BR>
<BR>
"Ni-MH battery that it?" <BR>
<BR>
"Ni-MH battery is the most environmentally-friendly <A title="Toshiba Satellite A70 Laptop Battery" href="http://laptopsbatteries.us/toshiba-satellite-a70-seires-battery.htm">TOSHIBA Satellite A70 Battery</A>, pay attention to environmental protection efforts of countries to promote the use of nickel-metal hydride batteries, as easy to recycle, and also to minimize damage to the environment. But nickel-metal hydride batteries with lithium compared, there are still some shortcomings . charging time longer than the weight of Shenyang, the capacity of small power than lithium, as well as memory effect. Although it is not like the memory of such a large nickel-cadmium batteries, but still need to discharge, the user must be exhausted before recharging. notebook case, mobile phones the same. " <BR>
<BR>
Later, I also understand that the lithium-ion batteries (or lithium compared fluently called) is also defective, such as high prices and fewer charge-discharge and so on. Li-ion battery charge and discharge frequency of only 400-600 times, specially the products to improve the 800, however. Charge a per day basis, the best lithium batteries for more than two years on only . And Ni-MH rechargeable battery number can be achieved more than 700, some good quality products up to 1200 charge-discharge times, such a comparison, the Ni-MH battery life than lithium batteries and nickel-hydrogen batteries than the price of lithium batteries much lower. In view of this, there is no perfect laptop battery. <BR>
<BR>
Know that the notebook battery materials, let us understand their origin. Notebook battery origin is Japan, South Korea, mainland China and Taiwan Province of China, especially in Japan, mostly because the battery notebook batteries used by almost all the Japanese manufacturers, such as: Toshiba, Panasonic, Sanyo, NEC and so on. Although many brands of notebook computers, batteries of different shapes, but the batteries used in a few Japanese brands, manufacturing batteries for the Japanese electronics company has brought big gains. South Korea, Taiwan Province of China and most of the main processing, production of the batteries are the core of Japan. <BR>
<BR>
Weight, shape and capacity <BR>
<BR>
The vast majority of notebook battery for a square, the market also has a small number of ultra-thin notebook using cylindrical batteries, such as SONY 505 series, Toshiba PROTEGE series (I have not seen a triangle). <BR>
<BR>
The weight of battery materials and models based on changes to the Toshiba 1750 as an example, it is with nickel-metal hydride batteries, weight of more than 500 grams, it brought me sad. I have seen in the market with a machine like the Toshiba 1750 is the same OEM manufacturers, and battery are also common. But they are using a lithium battery and weighing less than 250 grams, so that I envy. Mobile phone battery and then compared the results of the same. So, I have come to a conclusion, the shape of the same capacity with the nickel-metal hydride and lithium electricity, doubling the weight difference. <BR>
<BR>
Size from MAH cells to determine the mark, it seems that the Chinese name milliamperes. MA-hour notebook size is directly related to the use of time, I see the lowest notebook battery 3100MAH, the highest 4500MAH. Common sense said, 4500MAH battery life much longer than 3100MAH, but it can not be generalized. Battery life notebook also has a lot of configuration, for example say, Hewlett-Packard 6100 notebook using a PIII-M, MOBILITY RADEON graphics cards a number of energy-saving technologies such as hardware, with the 4000MAH battery, use up to 4 hours above. CPU desktop using the Toshiba 1800, although with a 4500MAH battery, the use of the time only three hours to reach. This also explains the use of laptop battery time MAH not only related to the energy-saving technology hardware is very important when purchasing the notebook needs to be multi-reference. <BR>
<BR>
Introduced a notebook of materials and the advantages and disadvantages of batteries. Further explore the use of laptop battery, we will issue six aspects. <BR>
<BR>
First, how the price of notebook battery? <BR>
<BR>
The level of the overall performance of laptop batteries the pros and inseparable from, the importance of batteries is also no less CPU, motherboards, hard drives and so on. Since the laptop battery is so important, expensive prices. As far as I understand it, the price of notebook batteries in 1000 --- ? ? 3,000, accounting for the overall price of the notebook's 10% --- 15% or even higher in some ultra-thin models. Toshiba in 1750 as an example: the price of the Toshiba 1750 is ? 9988, and its nickel-hydrogen batteries used must ? 1400. From this we can see, cost constraints of notebook battery has become an important factor in price. Compared to mobile phones, notebook battery proportion of the total price is not too high, the price of mobile phone battery is generally the total price of more than 30% to ? 1,000 phone as an example, the original price of the <A href="http://laptop-batteries-shop.com/apple/apple-ibook-g3-14-inch-series-battery.html">apple iBook G3 14-inch Series battery</A> is about ? 300 also be regarded as a big child. Here, the laser must be advised to treat your batteries, whether it is laptop or mobile phone. If it is because of your improper use of lead batteries OVER, may be too late to regret. <BR>
<BR>
Second, the battery manufacturers to provide what kind of warranty? <BR>
<BR>
As we all know, the manufacturers warranty on the notebook computer is a 1 year period --- 3 years. To enjoy the longest warranty in fact the only time CPU, motherboard, memory, hard disk; vulnerable components, such as: CD-ROM, LCD, housing, etc. can only enjoy a maximum of 1 year warranty; As for why the battery, there are three months of insurance , a security six months, the longest 1 year only; do not have the battery out of the warranty, buy a home if the laptop battery died the next day, you can only. As market competition intensifies, the battery is not the scope of the warranty is now a rare occurrence. However, the compact is to remind you that the purchase of the notebook, make sure the battery warranty to make sure the time and conditions, without a big mistake it carefully. <BR>
<BR>
Third, why do the battery warranty period is so short? <BR>
<BR>
I also asked this question a number of notebook dealers and manufacturers, their answer is: notebook batteries are easily damaged goods, the number of charge is constant, with a little time, used some hate, less than half a year on a reimbursement . Moreover, the notebook battery and other hardware different, there is no room can be repaired, only replaced, the so-called warranty is actually shifting. The products of such a long period of warranty (shifting), invisible among the vendors on the increased burden, as a profit-motivated companies, who are unwilling to risk such a big Tam. It appears that on the laptop battery 1 year manufacturers warranty is a mercy to the user greatly. <BR>
<BR>
Genuine laptop battery warranty that is the case, even we can imagine a parallel. The business has sales of parallel imports is no mention of the battery warranty, users are rarely asked. Once a user referred to this sensitive issue, vendors are not always the issue of batteries in general, bad shifting, such as a half-hearted. I can not think that the loss of informal support parallel accessories manufacturers, rely on the battery warranty? Is also used to deceive users of counterfeit products. <BR>
<BR>
Fourth, the proper use and maintenance does the battery? <BR>
<BR>
I saw the price and warranty on the battery of the introduction, you feel a little sensational, almost afraid to use the battery. In fact, in accordance with the proper ways to use, the battery can still live longer. Following on and you talk about the use of methods: <BR>
<BR>
1. Activator new battery <BR>
<BR>
You want your notebook battery life, there must be a good start, which may start from the purchase of notebook. The new notebooks in the first boot with the battery should be 3% of electricity, (this is also common practice of manufacturers. If you buy the first time to open the notebook and found that the battery is already full, must have been used by others.) At this point, You should not use an external power supply, the battery's remaining power is used up, until the shutdown, and then use an external power supply charge. After returning home, but also to the exhaustion of battery power and then charge, charge time must be more than 12 hours, repeated three times to do in order to activate the battery, so as to use for the future and lay a sound foundation. <BR>
<BR>
2. To minimize the use of the number of batteries <BR>
<BR>
This method gives, I feel like some small, but it is also the most effective. We should know that the number of battery charge and discharge is directly related to life, each time filling the battery to retire a step forward. Propose that we make full use of external power supply, use an external power supply when the battery is removed. Some friends convenience, often several times a day Plug Power, and notebook computers equipped with a battery, to do so, greater damage to the battery. Because each access to external power supply is equivalent to the battery once the battery naturally. Take for example our adult head, and he is 99 years of the notebook in August to buy enough for every day with the battery, the arrival in the use of external power supply. In August this year, he suddenly appeared in the issue of laptop batteries, standby time of two hours from the original drop to less than 1 hour, which is beyond cure battery performance of the most obvious, he can only use the silver shining white and changed a new battery. From here, he would have added to the battery treasure, no longer work with the battery, and only when necessary for the use of batteries. A monthly charge for the battery release, he said that doing so can extend the battery life can reduce the weight of the notebook is a double benefit. Adult head I learned to put up a wake, from the beginning of August, I no longer carry the batteries. My notebook model is built, to bring the weight of batteries is 3.2 kg, or as a result of nickel-metal hydride batteries, and weighing 1 kg, and remove the battery for my notebook is the most effective way to lose weight. Try to think of the expensive laptop battery price, I'll wait for the poor or the less better. <BR>
<BR>
3. Electricity charge and avoid the exhaustion after the long charging time <BR>
<BR>
Regardless of your notebook to use nickel-metal hydride or lithium electricity, must be exhausted before sufficient power (power consumption less than 1%), which is to avoid the best way memory effect. There is no power on the memory effect of lithium is, I have been in the first half that it is irresponsible to mislead merchants. Lithium would be the same memory effect, but its memory effect than Ni-MH small number of them. Rechargeable battery and cell phone the same, when you charge the battery to the notebook as far as possible, to avoid too long, the general control within 12 hours. <BR>
<BR>
As regards the prevention of exposure to prevent damp to prevent the erosion of liquid chemicals, <A title="Compaq Presario V4000 Laptop Battery" href="http://laptop-batteries-shop.com/compaq/compaq-presario-v4000-series-battery.html">Compaq Presario V4000 Battery</A> to avoid contact with metal contacts, such as attention, radium is not much here to mention. <BR>
<BR>
Fifth, the protection of batteries, notebook makers of the coup? <BR>
<BR>
As far as I know, many notebook manufacturers have to take into account the vulnerability of the battery and the product is added to the protection of the battery technologies, such as: IBM, HP, Toshiba, Compaq, etc.. Consider the most thoughtful of them is IBM, IBM laptop battery discharge can be detected, the power consumption of less than 2% until after the one-time charge. This can play a very good protective effect of the battery, is also worth drawing on other manufacturers. <BR>
<BR>
Sixth, the battery has a problem how to remedy the situation? <BR>
<BR>
A friend of mine to see here may be asked, if the battery standby time has been shortened significantly, serious issues such as the memory effect to remedy the situation? You may wish to try the following method: First of all, the closure of access to BIOS in power management, because many notebook computers have power-saving mode, when the power will automatically shut down too low. And then restart the computer, before entering WINDOWS by PAUSE key, stay in the WINDOWS screen until the battery depletion and shutdown, repeat 3 times after charging. You can also use the discharge IBM software can go to IBM web site to find, name ISBR01WW.EXE. As the discharge cumbersome software methods, the results would be similar and have just introduced here is not recommended to you. <BR>
<BR>
Batteries according to the above method to remedy the generally better results can be received. If your battery has not improved after use, I have been helpless. <BR>
<BR>
Through my introduction, you have a new laptop battery to know about it? I hope you are able to treat notebook batteries, As the saying goes, good steel by the knife's edge, notebook batteries used in most need, it can make more contribution for you. <BR>
