Some time ago ready to buy books, they find some information online, is now posted over, although the copy, but I hope for your help.
1, common types of laptop batteries and their respective advantages and disadvantages? Should choose what kind of battery?
Commonly used in civil laptop battery can be divided into three types: nickel-cadmium batteries (Ni-Cd), nickel-metal hydride battery (Ni-MH) and lithium-ion battery (Li-Ion). Their characteristics are described briefly as follows:
Nickel-cadmium batteries: nickel cadmium batteries were the first types of acer aspire 3000 battery used in notebook computers, because of the battery production technology, production technology is not advanced enough, so the nickel-cadmium batteries have many shortcomings, such as capacity, small size and large. Nickel-cadmium battery charge and discharge times of about 300-700 times, but in the charge-discharge process if not handled properly, there will be "memory effect" (so-called "memory effect" is the battery before charging, the dell xps m1210 battery has not been completely exhausted, over time will cause the battery to reduce the rated capacity), making the service life shortened. In addition, cadmium is toxic, and therefore not conducive to nickel-cadmium battery protection of ecological environment. Makes a number of shortcomings have been eliminated from the nickel-cadmium batteries laptop battery applications.
Ni-MH battery: laptop battery type used in the second generation nickel metal hydride HP Compaq mini 700ek battery, nickel metal hydride battery nickel-cadmium batteries have a relatively greater than the energy density, which means no additional weight in the case of Ni-MH battery can be effectively extend the laptop working hours. Ni-MH battery life is very long, up to 1000 times charge-discharge Ni-MH battery Another advantage is greatly reduced in the presence of nickel-cadmium HP omnibook xe3 series battery"memory effect" problem, which makes nickel-metal hydride batteries can be more convenient to use . Ni-MH battery is the most environmentally friendly battery, it is no longer the use of toxic cadmium, heavy metals can eliminate the problem of pollution of the environment. Some countries have strong focus on environmental protection to promote the use nickel-metal hydride Dell d6400 battery, because it is easy to recycle. Ni-MH batteries because of their high cost, but also environmentally friendly, so there are still some manufacturers use it for laptop computers.
Lithium-ion battery: Lithium ion battery with a light weight, large capacity, no memory effect, etc., and have been widely used - the vast majority of laptops now use lithium-ion battery, although its price is relatively expensive. Lithium-ion batteries in laptop batteries currently the highest energy density, its capacity is the weight of the nickel-metal hydride batteries with 1.5 to 2 times, and has very low self-discharge rate. Lithium-ion dell inspiron 6000 battery have no "memory effect" and does not contain toxic substances, etc. It is also widely used in notebook computers of the important reasons. Although lithium-ion battery life is shorter than the nickel-metal hydride battery (usually about 400-800 times the number of charge-discharge), but for their daily use of the state, the nickel-metal hydride battery performance significantly better than lithium-ion battery, so you should try to choose lithium laptop.
Most notebooks currently on the market uses a lithium-ion Dell inspiron 15r (n5010d-278) battery (commonly referred to as lithium batteries), you can purchase or access to the vendor instructions consult the relevant information to confirm. Remainder of this article unless otherwise specified, are for the case of lithium batteries.
2, why when buying batteries with some power, this normal?
Most of the new laptop Sony vaio pcg-f809k battery at the factory, will be pre-filled for a certain amount of power used in the test machine, which is a normal phenomenon, not necessarily the reason has been used. But we should note that: first of all to this part of the battery depleted before recharging. (Reasons for doing so and how to discharge, the discharge level as I'll explain.)
3, Why buy when you pay attention to see the COMPAQ presario cq60-100 ac adapter battery charge and discharge times? How to view?
Many people think that the laptop's battery life is calculated according to life, it is not true, the real factors that should play a decisive role is to fully charge and discharge times (this is not part of a special case of laptop batteries, rechargeable Hp Pavilion dv9000 Battery are so all) . As already described, in normal use, the lithium-ion battery for about 400 charge-discharge life. There are some JS to renovate the old battery, or the appearance of the prototype for sale, if not pay attention to it is easy to buy a used battery, this "underlying problem" of the battery, how can you expect it to your long service? So we should pay attention to the use of software to buy to see the number of battery charge and discharge, in general, the new Dell XPS M1730 Battery should not exceed 3 times.
Specifically, the number of statistics that the battery is discharged to only 50% (this ratio is different in different types of batteries) and re-charge when the following will increase, for example: if you only discharge the battery again to 90% on it is full, this will not increase the number of statistics, but the ACER Aspire 5715Z Laptop AC Adapter battery is due to repeated charge and discharge and reduced life expectancy, so this parameter can only be done without having to use auxiliary judgments to blindly believe.
So specifically, how to view the battery charge and discharge it? Unfortunately, not all brands of notebook computers can view the battery charge and discharge times, as far as I know, only the first wife ibm and sony Nikon EN-EL12 Charger battery used in its related design, you can use special software to read the battery's internal chip test the data obtained, other brands can not.
IBM: IBM laptop called Thinkpad Configuration will be pre-installed programs. Click the program icon in the task tray selection Battery Information, in a pop-up window, select "Status Detail" (Detailed Status) tab, the last line of the display of information to have a "Cycle Count" instructions, which is Acer Aspire 1410 Battery has a charge and discharge times.
SONY: To see the SONY VAIO laptop battery information, you can double-click the PowerPanel software pre-installed in the task tray icon will pop up a Battery Information window, click on the interface of the Battery Information Advance (Advanced) button, A small window pops up to tell you more information on Motorola GP1200 battery, which is shown in Charge Cycles charge and discharge times.
4, how to test the battery status?
Some friends will say, I purchased not SONY, IBM notebook how to do? Should not be able to understand the performance and battery status it? Oh, but fortunately we have a very professional generic software can let you know your laptop battery in the end how much time to work, so as not to appear when the batteries need to use it "strike" the embarrassment, this is the Toshiba Tecra a2 Battery Mark 4.0.1. We can be found online.
5, the new battery should be fully charged before discharge? How to properly operate?
Battery type described above have already said, although in theory to lithium batteries have no memory effect, but in fact it is a memory effect, but only slightly. Therefore, we will go home after the laptop, do not rush to use first, the first new SONY CCD-TR840E Battery should be done using the original of the electricity to charge again. The specific method is to use the battery in a separate case without an external AC power supply can be fully discharged in accordance with the following steps to complete the operation (in Windows XP as an example): Click Control Panel - Performance and Maintenance - Power control - alarm, power shortage warning prompts cancellation use to power a serious shortage of alarm (the alarm is set to 1-2%), can be considered to have fully discharged and shut down (be careful not to use to power itself off, so there is no difference with the power-down, there is some damage to the notebook ); discharge is completed, then charge to fully charged (preferably in the off state, and do not unplug the power drop in the charge, and when the charge indicator turns off when charging will continue for some time, a lot of time the SONY NP-F330 Battery is only at this time 80-97% of electricity), while the power back to the original prompt prompt warning alarm condition. Note that charging is complete, you should wait 30 minutes or so until the battery is basic to cool before use.
6, the depth of the concept of charging and discharging correct?
For the use of lithium Panasonic Lumix Dmc-fx33 Battery, before most users are used to form the head three times the depth of the surface charge and discharge rules, may be a lot of friends in a lot of information and even the official website to see a similar note, what is more, some Users can also use such an extreme depth of discharge the following methods: in the BIOS, run out the final charge, the battery can not start up until the machine until the optical. Recently, users have this issue to IBM technical support send an email, get a reply is: It clearly states in the document that you do not deep charge the Li-Ion Acer Aspire 5720 Battery. The deep charging only applies to the NiMH batteries. (Chinese meaning: In this document very clearly that you do not charge for the lithium-depth, depth charge only for the nickel-metal hydride battery is concerned). The official answer from IBM's technical response message. The relevant pages in the IBM Web site also has instructions: NOTE: It is not recommended that you deep-discharge Li-Ion batteries. (Chinese meaning: Description: I suggest you not to lithium Canon g20hi Battery depth of discharge). This is before the majority of users in the concept of the formation of the concept is completely different, but since IBM has such an authoritative answer, we should pay attention to and observe the final result based on actual use. A friend has been reflected in actual use, there has been a result of such an extreme depth of discharge capacity is leading to decline in actual instances of the battery.
Therefore, I propose: the first three in the HP EliteBook 2530p Laptop AC Adapter battery can be fully described in the previous charge and discharge (and not the extreme depth of discharge method) in order to fully activate the lithium battery; As for charging, the vast majority of notebook computer batteries due to the current design has been Built-in overcharge protection circuit, it is generally not occur due to damage a battery overcharge.
7, external AC power supply using a laptop computer, should take off the battery?
As already described, the Dell Studio 1747 Laptop AC Adapter battery life not by the total length of usage time, but by the actual charge and discharge times (not the number of test software statistics) to decide. If the battery is always installed on your computer does not take off, removing the AC power, because of the lithium environment in which the insulation is not absolute, and the battery in the integrated control circuit, so even if the computer is turned off when the battery power will gradually discharge. Again connected to AC power, the battery will start charging (the battery is designed to power the majority of 95% or less began to charge different types of battery design is different), so whenever the power on or off, the battery will be recharged repeatedly and discharge. This practice has a strong memory effect of Ni-MH power TOSHIBA SATELLITET1960CS Laptop DC Adapter battery damage is very large, although the lithium-ion battery electric memory effect is relatively small, but a long time will not fully charge and discharge a certain extent, reduce the battery life ; In addition, the heat generated by the computer at work also will affect battery life.
Therefore, a stable power supply in the computer using the case of the environment, suggest that you remove the battery and use a separate power adapter. The aim is simply to avoid frequent Nikon Coolpix P5100 Charger battery discharge in the case was not fully charged. Of course, if you use a computer power supply situation is very bad environment and you do not have an external UPS uninterruptible power supply, the better to play a UPS battery is connected to the role, after all, and the hundreds of thousands of prices compared notebook computers, a battery is still relatively cheap, do not pick up a pound-foolish yo!
In addition, some models of laptop did not design the Dell Pa-12 Laptop AC Adapter battery compartment cover, remove the battery in the body will be missing a large piece of aesthetic impact; some notebook batteries also designed weight plays a role, after removing may affect body balance. This part of the user can choose according to their own preferences (like some dilemma: (huh, huh).
8, how to keep the battery removed?
Remove the Dell Studio 1535 Laptop AC Adapter battery storage conditions is also a need for attention. In general, you should pay attention to environmental temperature of 15-30 degrees Celsius, and stored in dry and ventilated place.
In addition, because the vast majority of notebook computers use lithium-ion batteries do not use if for a long time, often prone to "over-discharge" phenomenon, may no longer be able to charge. So if you need to save the battery for a long time on hold, then make sure to leave some FUJITSU Amilo A1667G Laptop AC Adapter battery power, all manufacturers to stay exactly how much of the remaining capacity theories, but I suggest that you save a full charge is good; other long-term use The battery in a month at least according to the aforementioned right way to conduct a full charge and discharge is to be done to work the purpose of doing so is to prevent ion Acer Aspire 5535 Battery has not been used in the case of long-term loss of electrical activity which led to no longer re-charge.
