Books battery maintenance tips
Now appearing on the market penetration is the highest lithium-ion battery (Li-ion) Therefore, this article will focus on lithium-ion battery. Know your laptop battery you need to understand the following parameters: battery capacity, rated voltage, normal use temperature.
    Volume size, mainly from the marked mAh battery to determine its Chinese name is mAh. MA when the size of the laptop battery is directly related to the use of time, but it can not be generalized. Laptop battery's capacity is not to say bigger and more sustained supply and use in the actual process of using the endurance are closely related to the notebook power consumption. We can imagine a laptop to configure the greater the higher the energy consumption, the greater the amount of computing power to run the speed of passing the sooner.
   Normal working temperature of the battery can work temperature range, the use of non-normal temperatures likely to be dangerous (explosion), and the unnecessary trouble (leakage, a power outage).
   Production date, which in some older models of laptop batteries will appear, it is a direct reflection of your piece of the battery can use the length of time, which is to determine the normal use of a battery time is very important parameters. So we buy a notebook it is time to pay attention to the battery of the production date, even if the new battery put a longer time of his life there will be reduced accordingly. For users who want to buy second-hand books is the parameter should pay attention to this area
    Exactly how to distinguish the parameters of the battery does? From the above picture we can see the battery category used in Li-ion, lithium-ion battery that is. Rated output voltage 10.8V, capacity of 4800mAh. Of course, there are manufacturers, production, the normal working temperature (0 degrees -60 degrees Celsius), at present, the identity of such batteries are used, we can enlarge the picture above to learn about their notebook battery some basic information.

Laptop battery maintenance methods - 1 activate the new battery want your laptop battery longevity, there must be a good start, which was talking about from the purchase of notebook. The new notebooks in the first boot with the battery should be 3% of the electricity (which is also common practice firms. If you purchased the notebook open for the first time and found that the battery is already full, must have been used by others), this time, you should first do not use an external power supply, I put the battery inside the power exhausted, until the shutdown, and then re-use an external power supply charge. After returning home, but also the battery charge after the exhaustion of power, charging time must be more than 12 hours, repeated three times to do in order to activate the battery, in this way can lay a good foundation for future use.
  Laptop battery maintenance methods - 2, to minimize the use of this method gives the number of batteries I feel like some petty, but it is also the most effective. We should know that the battery charge and discharge frequency is directly related to life on one charge, the battery on a step forward to retirement. Suggest that you try to use an external power supply, use an external power supply when the battery removed. Some friends convenience, often several times a day Plug Power, and notebook computers equipped with a battery, to do so, even greater damage to the battery. Because each access to external power supply is equivalent to the battery charge time, battery life shortened by a naturally.
   Laptop battery maintenance methods - 3, after the exhaustion of electricity charge and avoid charging time is too long regardless of your notebook to use nickel-metal hydride or lithium-electric power, it must take charge after the exhaustion of power (capacity less than 1%), which is The best way to avoid the memory effect. There is no memory effect on lithium to say, I have been in the preceding description is misleading and irresponsible businesses. Lithium-Ion battery memory effect will be the same, but it is the memory effect than nickel-metal hydride smaller Bale. Mobile phone battery charging with the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the battery contacts with metal objects such as attention, not much to mention here also.Dell Inspiron E1405 battery          HP PB994A battery        Dell Latitude C600 battery

Laptop battery form: Common brands of laptop batteries the vast majority of the square. On the market also has a small number of ultra-thin notebook using cylindrical batteries, such as the SONY 505 series, Toshiba PROTEGE series, Sony R505 laptop batteries Photo (2), Sony V505 laptop battery picture (1) Sony TR laptop battery picture (1) and so on.

Laptop battery weight varies according to the material and models, such as the size and shape of the same nickel-metal hydride and lithium electricity, the weight is far too small.

Notebook battery capacity, mainly from the size of the marked mAh battery to determine its Chinese name is mAh. MA hours the size of the notebook directly related to the use of time, but it can not be generalized. Battery life notebook configurations with a great relationship, for example Well, the HP 6100 notebook 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 or more . Using the Toshiba 1800 desktop CPU, although equipped with a 4500mAh battery, use of time can only reach 3 hours. Able to meet the needs of the general going out to work. This also indicates that the notebook battery mAh not only related to hardware, energy-saving technologies is very important.IBM R50 Battery   Dell 1520 Battery

As the prices continue to lower, laptop computer is at an unprecedented rate into more people's lives. Compared to ordinary PC, the notebook easy to carry, is a mobile office and entertainment, the choice of. But there still exist many problems in NB, in which first and foremost problem is the battery duration is too short.

Now a new laptop battery commonly used in between 2 hours ~ 6 hours, as the battery ages, this time will be shortened. Battery working time of 6 hours or more a few laptops, but also expensive. NB Many users will be confused from time to time, in the pamphlets with the words "life time of up to eight hours," and buy it back later, only 3 hours or so it can be used.

In fact, many business advertises a "life time" is turned on energy-saving state, the screen brightness set to minimum, and do not use a computer case, the battery can sustain the longest time. NB the vast majority of users do not open your computer to do the Hao Zhao, as long as the computer is in working condition, whether songs, typing, or the Internet, the battery's working time is always more than pamphlets on a lot less.

Buy laptop batteries at the store, it can not easily buy a right to take away. The battery testing is an essential part. First, view the focus of the test charge cycles, and second, standby time. Many people think that laptop battery life calculated in accordance with life, in fact, the real factors that play a decisive role should be to fully charge and discharge times. In general, the international brand of notebook product line will be included in its software, which offers a management tool for the battery. This tool by reading the battery pack inside the intelligent control chip to see such as the use time of battery design capacity, actual capacity and charge-discharge times and other information. Through which users can understand some of the cell surface, not visible label information.

 
       If the purchase is a new original equipment batteries, rechargeable batteries should pay attention to whether the frequency of 0 (number of charge cycles up to 2 ~ 3 times, because some merchants have to purchase the battery after the charge and discharge test). Second is to check the battery capacity. The battery fully charged capacity and design capacity of the comparison, if we find completely filled with a lot of capacity is less than design capacity, indicating a significant reduction in battery performance have not recommended for purchase. If your laptop's battery management program does not have the see the battery fully charged capacity options, such as using software to detect BatteryMon.

Now, some people may be misunderstanding of lithium batteries, lithium batteries do not remember that, in fact, lithium is not without memory, but only relatively small memory, it seems not very clear. And lithium batteries can be divided into lithium and lithium-ion battery two kinds. 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, lithium can inhibit the added element of 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 battery for LI, lithium-ion battery LI-ION. Lithium and nickel-metal hydride rechargeable batteries Another difference is the number of electric charge in general the number of lithium to only 400-600 times, specially modified products, but 800 times, generally used for 2 years or so abandoned, and this is why the general notebook manufacturers to take a year just on the battery pack repair reasons. But relative to the lithium batteries, Ni-MH battery charging times much more than is necessary, usually 700 or more good quality battery can charge and discharge 1200 times, Ni-MH battery life than lithium batteries often has.

 Laptop battery will be charged with the increase in the number reduced life expectancy, so set the appropriate charging threshold is more important. Charge threshold generally have three options, namely: Always charging, charging is automatically set thresholds and custom. Often use battery-powered user can choose to always charge the battery under the age of Jiu Ji batteries. Instead of the users often use battery-powered, do not choose this. Charging threshold is automatically set by the power management software, according to the actual capacity of the battery charge calculation of a reasonable threshold. This method is recommended in general users. And third, the custom is the computer expert to use, when the user right notebook computer knowledge learned to a certain extent, self-definition is the best way.

    Most users are using the AC power to the laptop power supply, less battery. Started after the battery in the production of auto-aging, the battery remaining capacity is not excessive and long-term discharge will shorten the battery life. That are not commonly used in batteries, can charge its battery to 30% ~ 60%, and then sealed with wax paper and placed no direct sunlight and well-ventilated place. For the longer period of time without the battery, but also ensure that charge and discharge once every six months to ensure that the battery life.

Battery MaxMiser power management software can display the Laptop Battery temperature and discharge current, but not every brand-name products have this powerful.

In order to maintain the BIOS state, a lot of notebook computers that have the battery calibration option, simply speaking, this function will laptop battery is full and then discharge to the total without electricity
, And then filled again, so not completely discharge for long-term accumulative error caused by a certain degree of corrective action. However, please note the correction in the BIOS of time spent relatively long,
If you do this, preferably before going to sleep.

Many models also have Windows, discharge functions. This can save time, while working will be corrected:). Laptop battery calibration should not be too frequent
, Frequent deep discharge is to bring laptop PC battery life shortened, it is recommended two to three months to do it once.

When the discharge voltage drop across more than drop quickly, the system can easily mistaken for a voltage not enough, lack of electricity. (In fact, there is no electrical discharge).

Can see from the above laptop battery is a vicious cycle of aging process of the discovery of notebook batteries lost capacity when more and more what it should be tempered, or else it will hang up sooner or later ... ...

The other is a lot of Li-ion battery pack as a whole failed because the battery pack inside a failure caused by batteries. Mouseexcrement bad pot of soup
. This phenomenon can not be avoided, because the battery The nature of each section can not be fully consistent with a long time there is a bit poor quality, the first of some aging.
Undermining the overall (after concatenation) of heavy discharge curve, that is that bad the first full battery charge and discharge also finished the first release.

Mentioned above, a lithium battery, battery-points of several books in the end it? We take a look at the general books are divided into the battery nickel-chromium batteries, nickel-metal hydride batteries, lithium batteries of three. Nickel-chromium batteries, battery size due to large amount of weight, size small, short life, there are disadvantages such as memory effect, the market has been abandoned. At present two kinds of lithium and nickel-metal hydride to the market mainstream, in which lithium has a small size, light weight, large capacity, low memory effect, charging time is short, etc., have been extensively used by manufacturers. Lithium-Ion battery was divided into two kinds, one is a lithium battery, another is a lithium-ion batteries. The existence of lithium, such as burning, the bursting of insecurity has been suspended. Subsequently improved lithium-ion batteries, in line with the safe, efficient, convenient standard, and to become market-driven. As for the nickel-metal hydride batteries, it can be said is in line with the theme of the recent advocacy of environmental protection, mainly due to its recycling features! But there are also shortcomings, such as the charging time length, weight, capacity Lithium-Ion battery smaller than the disadvantage. But the more charge cycles than lithium-ion battery 400 ~ 600 times the mean, nickel-metal hydride batteries a record high of 1,200 is very attractive!

Then began to use nickel-metal hydride notebook (NlMH) HP DV2000 Battery, this battery has a good price and large power, the same time, "Ni-MH battery is one of the most environmentally friendly battery, pay attention to environmental protection, countries have strongly advocated 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 disadvantages. charge a long time and a heavier weight capacity than a small lithium battery, the battery continued to discharge time too short, there is memory effect, and its memory, while not as big as nickel-cadmium batteries, but still need to discharge, the user must be exhausted before charging.
   Ni-MH battery soon be lithium-ion (Li-ion) battery replacement. Lithium-Ion battery will have a long time ago, and began its use is not safe, we often see charging when burning, bursting, perhaps because of the sake of lithium element too active. Then there is an improved lithium-ion batteries, lithium can inhibit the added element of active ingredients, so that lithium really a safe, efficient, convenient, while the older Lithium-Ion battery also will be eliminated. They are also very simple distinction, from the battery label will be able to identify, lithium battery for Li, lithium-ion battery for Li-ion. Now, laptops to use the so-called lithium, in fact, lithium-ion battery. Lithium-ion battery energy storage density, may at any time charge and continued to discharge a long time, generally about 3 hours. The size of the battery capacity of the main from the marked mAh (milliamp hours) to determine the value, such as the 3000mAh, 4000mAh and so on, value the greater the greater the capacity of the battery.

Fuel Cell (Fuel Cell): Fuel cells are the future of Laptop Battery star, it has many types, including proton exchange membrane fuel cell (PEM), alkaline fuel cell (AFC) and solid oxide fuel cell (SOFC) and many other However, due to the fuel cell start-up time and operating temperature and other reasons in fact suitable for notebook computer use only the fuel cell proton exchange membrane fuel cell (PEM). PEM fuel cells using methanol fuel, from the positive and negative electrodes composed of the principle of its power generation is the result of the methanol, after re-enter the negative hydrogen and oxygen enter the cathode, through the catalyst, hydrogen atoms into protons and electrons, by different paths into the cathode, e-cycle to produce electricity through an internal, proton through the electrolyte to achieve positive, combined with oxygen to produce water and electrical and heat. The experts agreed that restricting the commercial application of fuel cells, the biggest factor is the fuel cell to use the metal platinum (Pt) or platinum as catalyst to make the cost of production has been high, the current production cost of the fuel cell 500 ~ 1000 USD / kW. Research shows that only when the fuel cell production costs fell to 50 U.S. dollars / kilowatt level can be truly accepted by consumers. The high cost of fuel cells is mainly due to mass production has not been formed, once entered mass production stage, the price of fuel cells will certainly be greatly reduced.
