Laptop Battery ,how much do you know

The birth of the day from the laptop, the battery of this “servant” had been accompanied on its side, there is no battery, it can be said can not be called the laptop “mobile computer.” With the notebook performance and technology continues to improve with the improvement, it is the “servant” of the “quality” is also getting higher and higher, from the past, nickel-chromium batteries, nickel-metal hydride batteries to now have been using lithium batteries may be popular even after the fuel the battery, few people care about this and notebooks are closely related to what – the battery, then let me work with you to look into the laptop battery.

The classification and distinction between the battery In general we use there are three kinds of batteries, 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-Ion battery LI, in recent years, In the notebook field has also been a fuel cell, its only by-product of water and heat, no noise, the basic pollution-free, efficient power generation systems in general higher than the multi-reach 43 ~ 58%, if the heat produced by the reaction utilization, efficiency can be up to 80%! Is a clean and environmentally friendly power. Because of Dell GK479 its technology was not perfect, there are still many problems to be solved, and now it is in terms of cost, size, weight, ease of access to fuel, both absolutely can not and traditional lithium batteries and polymer lithium battery to compete.

NI-CD Ni-Cd batteries because of their age is too early, so have many of the shortcomings of a headache, such as: bulky, heavy weight, capacity, small, short life, there is memory effect, etc. (useless), and now no longer in use. Now mainly NI-MH battery Ni-MH and LI lithium two kinds. Ni-MH battery which is also active in the battery industry, 1:00, compared to other batteries, nickel-metal hydride batteries to be more environmentally friendly some, it is also by far the most environmentally friendly battery,like Dell xps m1730 battery while the lithium battery Well, with a small size, light weight, large capacity, low memory effect, charging time is short, etc., well received by customers love, but you will often see the back of the battery properly abandoned and handling lithium batteries instructions? Because the lithium batteries to discard will cause environmental pollution.

 

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.more like Vaio VGN-SZ battery 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.

 

Now that the market price of the original equipment batteries are very expensive, generally place around 1000-1500, so some of my friends started to replace the battery, through their own batteries to achieve the purpose of extending battery life. Theory should, it is possible, but due process reasons, the Presario V3000 battery batteries are generally used ultrasonic welding, there is no gap, it is difficult apart, even if the hardware is also very difficult to disassemble a close, I see the electronic Shangyuan to the two hands are their own battery replacement batteries and then sell finished, the battery can be a combination of Office, it is clear to see there are 502 marks, after gluing, even with batteries, replace more time to find a match difficult.

Notebook battery maintenance on

Jul 23

Posted by admin in Uncategorized | Comments off

Notebook in the use of a longer period of time, prone to the problem of declining laptop battery capacity, resulting in shortened life of the notebook battery . This is mainly an internal battery caused by aging or failure. In serious condition, the use of battery calibration procedures or repeatedly charging and discharging the battery fails. For this issue, there are many fans that will open the battery case, the failure to find and replace batteries will be able to solve the problem. The actual situation is really so?

Replacement batteries should be treated with caution

Due to the current use of lithium-ion notebook batteries , and lithium-ion battery life is basically a constant, the charge life of only 500 ~ 800 times. Therefore, if the regular use of batteries for notebook power supply, 1 ~ 2 years later, due to the internal battery, it is easy to achieve the life of the batteries expire. Although we have detected in the open cell batteries, the show is a one or two damaged batteries. However, due to other batteries that is about it even if you replace the batteries of the failure, the battery back to normal in a short period of time, will soon result of the failure of other laptop batteries of the entire battery can not be used again.

In that case, all the internal laptop battery can replace all solve the problem? In fact, this is difficult. Because in the original battery, its internal batteries is a precise match, and therefore the capacity of batteries, terminal voltage and internal resistance of a good consistency. And we are in the market to buy batteries, and has not been tested and matched, we can not be an amateur under the conditions of matching for the batteries, so the capacity, internal resistance and other parameters will inevitably vary. In the internal battery, the batteries are charged together after the series (in the majority of notebook batteries, the batteries will be divided into eight groups, four in series and then parallel to form a battery pack), as a result of the rechargeable battery the same current, in which the smallest capacity batteries will of course be full of electricity, while the other is not enough battery power, the battery terminal voltage can not set the voltage, charging circuit will continue to charge laptop battery pack . In this way, the original fully charged rechargeable batteries will be too. To reduce the charge time, laptop charging circuit of the charge current considerable, so too will charge batteries when the great heat, so that the liquid batteries temperature, pressure, internal electrolyte easily dry or overflow , resulting in a further decline in the capacity of batteries, and even expansion of the explosion there. The total storage capacity of the battery by one of the smallest capacity batteries that decision, and this will turn into a vicious cycle, after repeated charge-discharge, the entire battery capacity will significantly decline, resulting in the use of laptop time.

At the same time, a number of laptop batteries in order to prevent unauthorized users to open the replacement of batteries, have the smart chip protection and anti-line openings. As long as the shell to open the battery or batteries from the battery in the circuit board removed, intelligent protection circuit will stop the output of the battery. Even if we put the batteries back to the battery circuit board or close the battery case, the protection of its smart chip still can not be restored. In this way, the laptop battery will not be able to normal output. We need to reset the smart chip in order to solve this problem, but the amateur conditions, we are unable to reset the smart chip. Therefore, from time to time Open batteries may cause permanent damage to the battery.

So, how do we solve the laptop battery problem? The best way is to buy a new original battery, but now a new original battery or even a few thousand dollars, to spend so much money is too high, exceeding the carrying capacity of many consumers. However, there are a number of professional notebook repair station, its equipment and technology are good, but there are some repair stations and manufacturers of batteries there is a long-term cooperative relations, the battery can be manufactured to precise matching. This will ensure the maintenance of quality. In these places the price of batteries for about 300 million, although replacement of batteries on their own to higher prices, but will keep the battery’s long-term use. In addition, some maintenance stations for maintenance had also carried out a six-month battery warranty. And we use these six months, as long as there are a hundred times to ensure that the battery charge and discharge around, and laptop battery capacity and stability during this period, then after the battery will enter a stable period, the damage is not easy.

Have know-how to maintain the battery

In any case, replace the batteries do not need our small price to pay, so we have to use in day-to-day attention to the maintenance of the battery to extend battery life.

To protect the battery, first of all to reduce the number of battery, that is to say when in the city, do not use the battery as much as possible. This can reduce the number of battery charge and discharge, longer battery life. While this caused some inconvenience to use, but every time you think about the use of batteries, need money to pay two dollars.

The internal structure of the battery

Battery calibration procedures can extend the battery life, has been a subject of heated discussion. Support the view that correction can eliminate the battery memory effect of batteries to extend battery life. The opponents believe that the use of lithium-ion batteries have no memory effect, so the correction process will only increase the number of battery charge and discharge and shorten battery life. In fact, understanding these two are not comprehensive. Although lithium-ion batteries to reduce the memory effect, but the memory effect still exists. Indeed the battery calibration can reduce the memory effect, but this is not the most important, the battery calibration procedure is to establish the main functions of the battery and control circuit so that the control circuit can correctly identify the capacity of the battery, so to avoid battery overcharge or over-discharge phenomenon. At the same time, the system can also be exhausted before the battery shutdown to protect data security. However, the frequent use of battery calibration procedures will increase the number of battery charge and discharge. Therefore, we run once every three months about the battery calibration procedures it.

We in the use of batteries for notebook power supply or power adapter for charging the battery, do not unplug the notebook’s battery. Because the laptop battery is charging or discharging state, the currents are very large, if we try to plug the battery, then, it is easy to have a spark, not only will cause contact of ablation, may also be caused by the impact of current circuit board or battery laptop charging circuit damage.

In addition, many people there are still some misunderstanding on the use of batteries. For example, the “new purchase to go through the battery charging and discharging several times to activate,” “notebook batteries do need to put a” matter of fact, with the memory effect of lithium batteries and battery to reduce the improvement of internal protection circuits. These factors impact on the laptop battery capacity has been very small, we run on a regular basis as long as the battery calibration procedure of these operations will be able to eliminate the impact of the battery, so we need not care too much for this purpose to wait on your notebook, after all, the battery is used used.
