subject: Comprehensive Analysis Of Laptop Battery Pack [print this page] Most consumers are plans to buy a portable laptop. In fact, relative to the desktop, notebook and easy to carry in addition, there is a relatively large advantage is the use of rechargeable batteries,dell inspiron 1525 battery , so the use of the environment on the laptop has a lot of flexibility. So, in buying and using a laptop, we should know what about battery knowledge? In the following article, I will be Members.
Related to the performance of laptop battery notebook battery life, which is generally more important for business people, they often need to hold conferences or business meetings, notebook and other mobile applications. For ordinary consumers, usually most of the power to use the laptop, so for battery selection and maintenance is not so concerned about, and that notebook with a period of time, dell xps m1530 battery , life will be greatly reduced, difficult to deal with Some unexpected events.
Here the author is not very appropriate to give an example of the relationship between the laptop and battery, as comedian Stephen Chow and his voice actor Dan Banyu relationship, often overlooked, but is the first supporting role, not or missing. Therefore, consumers choose to buy and use a notebook, it should understand and learn the proper use and maintenance of the first notebook accessories. Next, the author of several important aspects from the to introduce the contents of the next on the laptop battery.
First, an overview of laptop battery
The first with a notebook computer battery is nickel-cadmium batteries, but this battery has a memory effect, each must be discharged before charging, very easy to use, and this battery still bulky, heavy weight, small size, life short defects, so the market has been abandoned. Then came nickel-metal hydride batteries, but this battery also has a memory effect, it is gradually eliminated by the market. Currently, the mainstream market, lithium-ion batteries,dell vostro 1310 battery , and lithium polymer batteries, lithium-ion battery which has a small size, light weight, large capacity, low memory effect, charging time is short, etc., so widely used by businesses. The lithium polymer batteries with high energy density, more compact, ultra-thin, lightweight, low cost and high security and a variety of obvious advantages, is a new battery.
The configuration table in a notebook or laptop purchase, the user will see or hear of a laptop equipped with a several-cell battery. So what is meant by this core? How to distinguish a cell in the end a few cell battery?
Core refers to the batteries, lithium-ion battery is a shell, circuit board and batteries,Dell latitude d620 fan , generally referred to a few people-cell battery means the number of batteries within the battery. 6-cell battery, said battery has six batteries.
As to how to determine a notebooks battery is a few core, there are two ways: The first way is to unplug the battery point of view the number of their contacts, several contacts in the tens-cell battery, but this method is accurate rate is very low. The second method is more accurate, in order to know the battery is a few core, we must understand two data, one is the battery voltage, the other is the battery capacity. Such as a battery voltage is 11.1V, capacity is 4400mAh, then the voltage divided by 3.7 to get 3, proved to be three small batteries together in series to form a battery pack. Because of the small battery capacity is 2200mAh, so must be parallel to the two groups together to achieve 4400mAh. According to these judgments, you can know if this battery is a 3 2 = 6 core.
Notebook standby time determined mainly by the battery capacity, usually a few more batteries, the greater capacity. Laptop battery currently divided into 3 core, 4 core, 6-cell, 8-cell, 9 cell, 12 cores. So simply, the greater the number of cores, longer life, of course, the higher the price, but stability will be less than the batteries to be almost. Laptop battery life is measured mainly by the number of charge cycles, usually 500-600 times, so the most effective use of batteries in 2 years.
The purchase of the notebook, the average home user does not have to particularly focus on a few core , because the main household, more stable power supply, such as 3-pin, 4-cell battery is good enough. And reasonable business people would choose a notebook battery, and if the life time is not critical, you can choose 6-cell or 8 cell battery, high stability, and distribution of life and portability are more reasonable. If the requirements of long life, then we would consider the 9-pin or 12-cell battery, but this notebook would be more weight is not easy to carry, and the stability is somewhat less.
Second, the laptop battery tips
Reasonable use of laptop battery is extended battery life, an effective means for battery maintenance. Many users of notebook battery life a long time, points will be fully satisfied, reduced life, aging and so on. Therefore, when using the laptop battery should be noted that some of the tips, and avoid some errors. Next, the author describes some of the laptop battery life skills and the attention.
1, the first charge laptop battery
Many consumers buy the notebook, the dealer will be informed, to be repeated three times on the new laptop battery is fully charged / discharged, the charging time of 12 hours or more preferably, to the activation of the battery. So short, it makes the majority of users access to a misunderstanding.
In fact, the laptop computer at the factory before the battery will activate, in order to avoid wear and tear affect battery performance, only a small amount of residual electricity. So get a notebook user is already activated off, and then said according to the dealer to do, the completion of a laptop battery is fully charged it will automatically stop working, not only is not necessary to maintain the charge time to 12 hours, and This is an increase of cell loss. Overall, buy a new laptop just follow the normal charge / discharge method can be used.
2, run out of electricity intentionally
Regularly run out of battery power, about once a month can to ensure a full charge. To completely run out of battery in the power, just let laptop running CPU-intensive tasks, such as some large-scale 3D game play, or watching HD video, so you can quickly run out of battery power, of course, these operations do not forget the need to unplug the power.
Of course, all of the battery before each charge and discharge is not necessary, but also harmful. Proved: the battery depth of discharge will be unnecessary to shorten battery life, it is proposed that under normal circumstances, when the battery is used in about 10% can be charged. But when the battery power is still more than 30% is best when not charging, because the memory effect does exist.
3, connected to the battery when the power is not to win
Many users are confused, when you insert the AC, or battery should be seized, in order to prevent repeated charge and discharge? In fact, this is not necessary. Because most of the notebooks power control circuit to design a feature that when the battery is below 90% or 95% will be charged, and the capacity to achieve this through natural discharge time of 2 weeks to a month. And even if the battery is charged again, bringing the loss will not be long without the battery than the loss caused by a large number. Also, if a user operation when the notebook power outage, not only on the laptop there is injury, but data loss is irreparable consequences.
4, learn to use power management
Windows power management built into the system, users can set according to different needs of different power plan, thus saving on the notebook, reducing wear and tear on the battery. In addition to the built-in Windows power management features, some notebook also comes with power management software (such as Lenovo notebook), rational use of these software, better able to control the charge and discharge laptop, increase notebook battery life.
Third, the efficient use of laptop battery
1, try not to use external devices
For some external device (such as USB devices, etc.), when using the battery should unplug them as much as possible, to save power. Large power consumption because some equipment, such as the USB interface external hard drive, external drives and other devices to connect these devices will greatly shorten the battery life.
2, disable temporarily the use of equipment and interfaces
In general, notebook computer equipment and some internal interfaces are not often used, if used with a battery-powered laptop, you can temporarily disable these devices and interfaces. In the Device Manager, double-click the device must be disabled, you can disable them.
3, turn off the screen saver
Many people think that the screen saver may be power consumption is not large, in fact, some of the complex screen saver may be more power than normal operation, it is recommended that the Dell PA-10 Adapter when not in use turn the screen saver function.
4, power alarm function is disabled
In the Control Panel, select Sound icon in the Sound tab disable the Low battery alarm and serious shortage of battery alarm function. When the battery is displayed as 0% of the time, still forced to use for some time, this time you should immediately save the data. Because the battery is completely depleted, the notebook will not give any tips on forced shutdown.
5, energy-saving settings
Built-in power options in Windows, or in the notebook comes with power management software, as much as possible to reduce the performance of the notebook. Such as the brightness dimmed, notebook does not operate automatically after 5 minutes into the sleep state, and so on.
Fourth, the laptop battery maintenance.
In addition to using the process of laptop battery some of the details and skills in everyday applications should also pay attention to the use of laptop battery environment, which also affect battery performance and maintenance of the battery is very important aspect.
1, to prevent high temperature, exposure
Room temperature (20-30 degrees) for optimum battery operating temperature, the temperature is too high or too low operating environment will reduce battery life. In testing, we found 100% state of charge the battery if maintained at a relatively high temperature (about 60 degrees Celsius), battery capacity will decrease 10% to 40%. Therefore, the high temperature will accelerate the decline in battery capacity, battery life and lower life expectancy.
Loss of large high-temperature state of the battery
2, the voltage stability
In the process of laptop battery, the voltage stability is also very important. Users should avoid the notebooks power adapter and power appliances (such as air conditioning, TV, etc.) connected to the same outlet.
Should pay attention to maintaining stable voltage
The reason is simple, high-power electrical appliances on or off instantly when the pressure will be formed and cause damage to the battery, and a number of high-power electrical outlet using the same short-circuit may also cause problems, prone to danger.
Summary: This article, a total of such purposes: one to introduce the basics of laptop batteries, allowing users to purchase when the notebook can be targeted to the choice of battery, and be able to clearly determine what kind of battery is more suitable. Second, to clarify the use of laptop battery some of the errors, allowing users to more clearly how to use the laptop battery. Third, the introduction of battery details and tips to help users better use of the battery, extending battery life.
