Most consumers are plans to buy a portable laptop. In fact, based on the desktop, laptop and slightly beyond wear, there is a relatively large advantage is the use of rechargeable batteries, so the use of the environment on the laptop has a lot of flexibility. So to use when buying a laptop and we should know what knowledge of battery?
Based on the performance of laptop batteries, which is usually more important for business people, they often need to conferences or business meetings, laptops and other mobile applications keep. For ordinary consumers, typically the most power on the laptop, allowing for battery selection and maintenance is not so concerned, and the notebook with time, life will be greatly reduced, difficult to deal with some unexpected events.
Here the author is not very suitable to give an example of the relationship between the laptop and rechargeable batteries, as comedian Stephen Chow and his voice actor Dan Banyu relationship, often overlooked, is the first supporting role, or not missing. Therefore, consumers choose to buy and use a laptop, it should understand and learn the proper use and maintenance of the first laptop accessories. Next, the author of several important aspects of the contents of the next will introduce on the laptop battery.
First, an overview of laptop battery
The first with a notebook battery is nickel-cadmium batteries, but the battery has a "memory effect", each in front of the store, very easy to be discharged, and this battery still bulky, heavy weight, small size the shortcomings of life in short, so that the market has been abandoned. Then came nickel-metal hydride batteries, but this battery has a "memory effect", it is eliminated from the market gradually. Currently, the mainstream market, lithium-ion batteries and lithium polymer batteries, lithium-ion battery, a small size, light weight, high capacity, low memory effect, charging time is short is, etc., widely used by businesses. The lithium-polymer batteries with high energy density, compact, ultra-thin, lightweight, low cost and high reliability and a number of obvious advantages, is a new battery.
Buy the configuration table in a notebook or laptop, the user will see or hear of a laptop with a multi-cell battery. So what is to be understood by this core? How to distinguish a cell at the end of some cell battery?
Core refers to the batteries, lithium-ion battery, a shell, circuit boards and batteries, commonly referred to a few people-cell battery, means the number of batteries in the battery. 6-cell battery, the battery has six batteries.
Furthermore, as for the determination of a notebook battery is a few core, there are two possibilities: The first option is to pull the battery point of view the number of their contacts, multiple contacts in the ten-cell battery, but this method is precise rate is very low. The second method is more accurate to know is, the battery a few core, we need to understand two dates, the battery voltage, the other is the capacity of the battery. Such as a battery voltage is 11.1, the capacity is 4400mAh, then the voltage divided by 3.7, to go to 3, to form three small batteries together in series to form a battery. Due to the limited battery capacity is 2200mAh, so must be in parallel to achieve the two groups together 4400mAh. After these judgments can one know if this battery is a 3 × 2 = 6-core.
Notebook standby time mainly due to the battery capacity, usually a couple of batteries, the greater capacity determined. Laptop battery currently divided into 3 core, core 4, 6-cell, 8 cell, 9 cell, 12 cores. So simple, the greater the number of cores, longer life, of course, the higher the price, but the stability to be less than the batteries are almost. Laptop battery is mainly measured by the number of charge cycles, typically 500 to 600 times, the most effective use of batteries in 2 years.
The purchase of the notebook will not have the average home user to concentrate mainly on a few core, because the main budget, stable electricity supply, as for example 3-pole, 4-cell battery good enough. And reasonable business people would choose a notebook battery, and if life is not critical to 6-cell or 8-cell battery, select high stability and distribution of life and portability are more reasonable. If the conditions for a long life, then we would hold the 9-pin or 12-cell battery, but the notebook would be more weight is not easy to carry, and the stability is somewhat lower.
Secondly, the laptop battery tips
Meaningful use of laptop battery Battery life is extended an effective means of maintaining the battery. Many users of notebook batteries for a long time, the dots can be fully satisfied, reduced ages and so on. Therefore should be considered when using the laptop battery to avoid some of the tips, and some errors. Next, the author describes some of the laptop-battery capabilities and attention.
1), the first charge laptop battery
Many consumers buy the notebook, the dealers 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 in short, it makes the majority of users access to a misunderstanding.
In fact, the laptop computer is to activate at the factory before the battery, to prevent wear of the battery power, only a small amount of residual current. So get a notebook user is already activated off, and then told to do by the dealer, the completion of a laptop battery is fully charged it will automatically stop working, not only is not necessary to keep the loading time of 12 hours and This is an increase of cell loss. In total, buy a new laptop, just follow the normal charge / discharge method can be used.
2) go out intentionally of electricity
Regularly run out of battery about once a month can ensure a full charge. To completely run out of battery in the power, you have a laptop with CPU-intensive tasks, such as how to play some great 3D games or watching HD video, so you can quickly run out of battery power, of course, make these operations do not forget that purpose and need for the power cord.
Of course, all of the battery before each charge and discharge is not necessary, but also harmful. Proved that the battery depth of discharge will not be necessary to shorten the battery life, it is proposed that under normal circumstances, when the battery is used in about 10%, can be loaded. But if the battery is more than 30% is best, if not loaded because the memory effect exists.
3) connected to the battery when the current is not to be won
Many users are confused when you insert the battery or AC should be used to prevent the repeated charge and discharge? In fact, this is not necessary. Since most notebooks to design power control circuit a feature that when the battery placed under 90% or 95% charged, and the ability to achieve this by natural discharge of 2 weeks to a month. And even when the battery is recharged, take the loss not be long without causing the battery than the loss of a large number. Also, if a user operation when the notebook power failure, not only on the laptop, there are injuries, but data loss is irreparable consequences.
4), learn to use power management
Windows power management built into the system, set the user according to different needs of different power plan that saves on the notebook, which reduces wear on the battery. In addition to the built-in Windows power management functions, some notebook also comes with power management software (such as Lenovo Notebook), efficient use of this software, better able to charge and discharge laptop, notebook battery life to increase . control
Third, the efficient use of laptop battery
1), do not try to use external devices
For some external device (eg USB devices, etc.), should the battery when using them as much drag as possible in order to save power. Large power consumption, because some devices, such as connecting the USB interface, an external hard drive, external hard drives and other devices to reduce these devices much the battery life.
2), temporarily disable the use of devices and interfaces
In general, notebook computer equipment and some internal interfaces are not often used, when used with a battery-powered laptop, you can temporarily disable these devices and interfaces. Must be deactivated in the "Device Manager", double-click the device, you can disable it.
3), turn the screen saver
Many people think that the screen saver may be the power consumption is large, in fact, some of the complex screen saver can have more energy than normal operation, it is recommended that when not in use turn off the screen saver function. HP Pavilion G6 battery
4), power off alarm
In the "Control Panel", select "Sound" icon in the tab "Sounds" to 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. Since the battery is completely drained, the notebook will not give any tips, forced shutdown.
5), energy-saving settings
Built-in Power Options in Windows comes in or the notebook's power management software, as much as possible in order to reduce the performance of the notebook. For example, the brightness dimmed, no laptop will not work automatically after 5 minutes in the resting state, and so on.
Fourth, the laptop battery maintenance.
Should pay, besides the use of the process of laptop battery some of the details and skills in everyday applications, their attention to the use of laptop battery environment that has an impact on battery performance and maintenance of the battery very important aspect.
1), with a high temperature to prevent exposure
Room temperature (20-30 degrees) for optimum battery operating temperature is the temperature too high or too low operating environment to reduce the battery life. In the test we have 100% state of charge of battery to be found, if obtained at a relatively high temperature (about 60 degrees Celsius) is reduced battery capacity by 10% to 40%. Therefore, the high temperature is the decrease in battery capacity, battery life and lower life expectancy accelerated.
The loss of the 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 laptop power supply and equipment (including air conditioning, TV, etc.) to the same outlet.
If you pay attention to maintaining stable voltage
The reason is simple, turn off high-power electrical devices on or off when the pressure is immediately formed and damage the battery, and a number of high-power outlet with the same short-circuit may also be problems, prone to risk .
Abstract: This article, in total for this purpose: one, to introduce the basics of laptop batteries, so that acquiring users when the notebook can be aligned to the choice of battery, and be able to clearly identify what type 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. Thirdly, the introduction of battery-details and tips for users to help make better use of the battery, extending battery life.
