Notebook battery trends

Posted by admin on April 26th, 2013

As an important part of the laptop battery from birth onwards caused widespread concern of the laptop battery owners of the mobile office. With the rapid development of laptop and handheld electronic products technology, its stability, time, volume and even the number of charge cycles, charging time are put forward higher requirements, and hp dv4 battery battery technology to follow the market demand, in many has made the improvement and development.

To reduce the volume reached at the same time extend the use of time, increasing the frequency of use, laptop battery adapter and reduce the memory effect of the negative impact such purposes, taking into account the cost of the battery and the use of security, battery selection constantly refined. Cathode material for lithium-ion battery, for example, can be broken down to the lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide and other raw materials. From a technical standpoint, battery lithium cobalt oxide-based. To further enhance the product’s energy reserves,Dell Inspiron 1520 Battery the higher level of technology of lithium nickel material is expected to enter the market in 2000. But because of the limited impact of the cathode material for battery characteristics, according to expert estimates, by the year 2000, the volume energy density of the lithium-ion battery in about 400wh / l, the minimum thickness of a single battery should be between 4 ~ 5mm performance almost do not have much room for development.

On the whole, the development of alternative new generation of the Samsung N150 Battery lithium-ion batteries battery is imminent, professional battery manufacturers are also actively selection and research and development work. Great deal of attention in the new material is expected to replace the lithium cobalt oxide, lithium metal rechargeable batteries. Metallic lithium rechargeable battery are the anode material to direct new type of rechargeable battery using lithium metal, its most important feature is that the battery anode metal material reaction, can give full play to the new battery’s energy reserves reached 2 times more than conventional lithium-ion battery, and in the discharge terms of capacity, even up to 10 times that of traditional products. Lenovo computer company has been concerned about the laptop dedicated to the development of efficient battery to maintain close contact with professional battery manufacturers invest a lot of funds to conduct an independent study, efforts to provide Chinese customers with efficient, economic latestToshiba PA3904U-1BRS battery technology.

Zinc-air battery is also replaced the leader in new materials of lithium cobalt oxide, it is the negative use of zinc, very characteristic. Air zinc battery free charging, there are certain problems, but the Compaq Presario V2000 majority of battery manufacturers are actively seeking solutions, I believe that the maturity zinc battery products will soon come out. —- It can be predicted that in the near future, whether laptop manufacturers or users will face more and more efficient and more practical choice, while the number of the birth of a battery of new technologies and new materials will future battery market a revolutionary impact.

Experts predict the future of the notebook computer can do in theory Lenovo B450 battery use time more than 20 hours, the entire battery module thickness of only 12.7mm (approximately 1/2 to 2/3), at the same time the weight will greatly reduced, so that more users to fully enjoy the fun of mobile office.

Laptop battery how to maintain?

Posted by admin on April 18th, 2013

Buy a notebook, is not on the notebook, such as their other half to take care of it? I believe that just bought. Many people only relationship like the computer system. Laptop battery you care about it?

Notebook battery maintenance began:
Step / methods
1.When power is connected, the Dell Inspiron 14Z battery can pull or not to pull, pull, pull depends on actual usage: do not disconnect the battery while connecting the DC power battery and does no harm, because the battery is not fully charged will no longer accept any power injection, power will all turn directly to the power supply system of the notebook. But when the high-speed operation of the notebook, internal overheating is best to remove the battery, otherwise it is harmful.

2.long-term use of the Lenovo B450 laptop battery how to save, pay attention to clean the dust inside the computer.
Laptop battery is put photoelectric save or fully charged, should save? Put photoelectric long-term preservation will make the batteries will lose their activity, and even lead to the control circuit protection self-locking and can no longer use the full power will bring long-term preservation security risks, the best method of preservation is to use electricity to about 40% and then stored in cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to take the battery out with time, both to ensure battery good state of preservation, but not so the battery is completely lost and damage the battery. When the computer for a long time in a dusty environment, it is best to regularly clean up the dust inside the notebook,Dell Inspiron 1545 excessive dust caused by poor heat.

3.How to properly charge laptop battery
Should try to avoid battery power light depleted rechargeable battery as this will give a lot of pressure resulting in damage. More feasible approach is to be charged in about 20-30% of the remaining power. In fact the notebook lithium battery in the number of “light / charge” there is a limit, all used up to recharge would greatly shorten the battery life. The same time, the battery should be charged the Dell PA-20 adapter in a dry place, Also note that the heat problem, which is the enemy of batteries.

4. Measures to extend notebook battery operating time
1 to reduce the brightness of the screen: You can use the fn + down / up key combination to quickly adjust brightness (specific FN + which keys need to see their own laptop).
2 make good use of standby, sleep and other functions: When long time without a computer,Dell XPS 15 ,allowing notebook standby or hibernation, both to save power and prolong the life of the computer.
3 to open cpu SpeedStep function, can significantly extend the battery operation time: cpu speedstep in the bios default boot When using the battery, the CPU automatically reduced frequency use, in order to save energy. Not open the boot by F2 into BIOS Performance, set Speedstep Enable as to “Enabled”.
4 when using theToshiba PA3715E-1AC3 battery, try to turn off the wireless, Bluetooth and infrared port. Removed without the use of peripherals to avoid to enable large 3D program, games, etc., to reduce unnecessary battery consumption.

Laptop battery structure and reasonable charge and discharge

Laptop battery structure and reasonable charge and discharge

The lithium-ion battery cathode materials are usually composed of the active compounds of lithium, the negative electrode is a special molecular structure of the carbon. The main component of the common cathode material LiCoO2, charging, added to the poles of the laptop battery potential forcing positive compounds release of lithium ions, embedded negative elements arranged in a lamellar structure of carbon. Discharge, lithium ion from the lamellar structure of the carbon precipitation and re-cathode combination of compounds. The movement of the lithium ions produces a current.

Reactions lithium toshiba battery cathode materials are usually composed of the active compounds of lithium, the negative electrode is a special molecular structure of carbon. The main component of the common cathode material LiCoO2, charging, added to the poles of the acer battery potential forcing positive compounds release of lithium ions, embedded negative elements arranged in a lamellar structure of carbon. Discharge, lithium ion from the lamellar structure of the carbon precipitation and re-cathode combination of compounds. The movement of the lithium ions produces a current. Should principle although very simple, in the actual industrial production, however, the need to consider the actual problem much more: a positive electrode material of additives required to maintain the activity of the repeated charge-discharge, the negative electrode material in the level of molecular structure to design in order to accommodate more lithium ions; filled in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also needs to have a good electrical conductivity, reducing the sony laptop battery internal resistance.

Although the lithium ion apple battery is rarely have the memory effect of the nickel-cadmium batteries, the principles of the memory effect of the crystallization, this reaction is hardly generated in the lithium battery. the lithium-ion battery for lg

capacity after repeated charge-discharge will decline, its causes are complex and varied. Positive and negative changes, from the molecular level, the positive and negative on the capacity of the lithium-ion hole structure will gradually collapse, clogging; From the chemical point of view, is the active anode material passivation, Vice reaction stability other compounds. The physical will appear on the cathode material gradually peeling, in short, ultimately reducing the number of lithium-ion batteries can freely move in the process of charging and discharging.

Over-charge and over-discharge, cause permanent damage to the sony batteries will be positive and negative, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ions and making it appear lamellar structure collapse over-charging lithium-ion will too hard into negative carbon structure, and makes some of the lithium-ion no longer be released. This is also why the asus laptop batteries usually equipped with a control circuit causes the charging and discharging.

Not suitable temperature, will lead to other chemical reactions within the lithium-ion compaq battery to generate compounds that we do not want to see, so many of the lithium-ion battery is between the positive and negative features the protective thermostat diaphragm or electrolyte additives. Batteries for samsung heat up to a certain case, the composite membrane film hole closed or the electrolyte degeneration, increased battery internal resistance until the circuit, the battery is no longer warming, to ensure that the temperature of the dell battery charging normal. Deep charge-discharge can improve the actual capacity of the lithium-ion battery? Experts clearly told me, this makes no sense. They even said, “activate”, three times a full charge and discharge before the so-called use their knowledge of Dr. figure out what is necessary. However, why a lot of people deep charge-discharge Battery Information marked capacity will change it? Will be mentioned later.

Laptops use lenovo lithium-ion batteries are generally with management chip and charge control chips. Management chip, a series of registers, there is capacity, temperature, ID, charge status, discharge times and values. These values ??are in use will gradually change. Personally, I think that the main role should use a month later in the instructions for use of the laptop should fully charge and discharge practice is to fix these registers where improper value, making the battery of gateway charge control and a nominal capacity of the battery match actual situation. The charge control chips to control the battery charging process. The hp lithium-ion battery charging process is divided into two phases, constant current fast charge phase (the battery indicator light yellow) and voltage current phase (the battery indicator light flashes green. Constant current fast charge phase, the battery voltage is gradually increased The standard voltage to the battery, and then transferred to the constant voltage phase control chip, the voltage will not rise to ensure that you do not over-charge current as the battery level rise gradually weakened to 0, and the final charge.

Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample ibm battery power, this is that we read in the Battery Information wh. Values. The lithium-ion battery in repeated use, the discharge curve will change, if the chip has been no opportunity to once again read out a complete discharge curve, the calculated electricity that is not accurate. Therefore, we need deep charge and discharge to calibrate the battery chip.

Laptop battery charge sufficient dissatisfaction with how should I do?

Posted by admin on January 29th, 2013

Has many friends in the day asked about laptop battery problem, the actual I have always said that the laptop battery is only notebook an essential accessory, we try to protect can not deliberate care, otherwise the machine faster not also keep a very The strong sony battery doing, nothing more than your second-hand laptop for sale only as a bargaining chip.

What percentage for the use, what to use to recharge it should be said that not too much stress, because of this, then the user will become very passive, the laptop battery is not so delicate. As for the battery using the AC or win on the machine are also as you will. Laptop circuit control much better than a cell phone, fully charged, it will automatically cut off the charging circuit and a small current loop in order to maintain the acer battery charge status, circuit control design good machines are less than 95% before they start charging, So you do not have to worry about such as apple batteries plug in to charge indefinitely ghost saying; win to save it, it is recommended to put a layer of plastic wrap out of the battery, which can be isolated from the dust, and a cool place, and then periodically take out with, enrich my knowledge, in order to avoid the asus laptop battery loss of activity.

There is also a question everyone is asking is also more whether it is necessary to calibrate the battery for compaq, how to calibrate the battery? Answers are necessary, because the instability factor of the battery in use and charging will cause a decline in the capacity of the replacement toshiba battery, but this decrease is not due to aging caused, so proper calibration can make this part of the loss of the capacity to recover . Regular battery calibration is a very necessary thing, for example, from January to February. Such as Compaq and IBM laptop BIOS or Power Management program provides a dell laptop batteries calibration feature, so use these two brands of friends can according to the instructions to perform. For those who do not provide this feature brand users can follow the following steps:

The screen saver is set to “no”

Settings in the Windows Power Management power scheme to “always open” and shut down equipment menu all set to “never”

3 In the Alarms tab will be “low samsung battery alarm” is set to 10%, the operation is set to “no operation”; “a serious power shortage alert,” set to 3%, operating as “standby”

4 screen brightness set to maximum

Sure all windows are closed, and to store the data of all previous work

6. Confirm the batteries for LG after charging more than 80%, unplug the power and all external devices, if the screen automatically reduces brightness, then turn it hit brightest

OK, you can go to sleep after the discharge end of the notebook will automatically shut down the power plug for laptop charging, attention must be completely filled and then boot, then restored to power scheme settings before calibration.

The purpose of doing so is to continuous low current discharge IBM laptop batteries, which discharge state in our daily use is impossible to achieve, because the normal state is inevitable changes in the operation of a variety of causes the current up and down. IBM, SONY such a machine can detect the lenovo laptop battery capacity before and after the change, other machines can download Master Lu to see, the capacity restored little by little, you will find, however, reminded here, if your hp battery has been caused by excessive use of aging, such palliatives is little use are not.

This method is also recommended that friends who are just new machine hand, general gateway lithium battery before it is put into use, preferably in accordance with this method for 2-3 times, put into positions the greatest possible so as to make batteries for optimal performance.

Maintenance skills as well as the proper use of laptop battery

The laptop battery is user using a laptop computer is an essential thing, when you need a mobile office or can not use an external power supply situation, we need to use the laptop battery, then how can better care of their laptop battery so that it provides more long life time? Next, I will detail about acer battery maintenance tips.

Now appearing on the market penetration is highest lithium apple battery (Li-ion). Know your laptop battery you need to clarify the following parameters: battery capacity, rated voltage, temperature normal use.

Capacity size judgment marked mAh asus laptop battery. MA when the size is directly related to the laptop battery use time, but it can not be generalized. Not to say that the greater use of the capacity of the laptop battery for toshiba time will be longer lg battery life is closely related to the actual use of the process as well as the notebook’s power consumption. Normally the next higher the energy consumption of the configuration of the laptop must be the greater, the greater the amount of computing power of the run, the faster the passage.

Rated voltage rated voltage is divided into notebook battery of lenovo and notebook rated voltage, generally both, there is a certain difference between the former refers to the longest stay during the time of the voltage sony laptop battery when the battery voltage drops during the discharge process. Laptop while charging use or just has been charged, the voltage will than use only the replacement ibm battery. Therefore, the rated voltage of the battery marked slightly lower.

Normal operating temperature is the the battery for gateway normal working temperature range, it is possible to use in the non-normal temperature hazardous (explosion), and unnecessary trouble (leakage, a sudden power failure), general battery rarely occur in the course of this kinds of situations, but in use, not the effect, to avoid the hp batteries close to hot or cold objects.

Exactly how to distinguish between the parameters of the battery?, We can see from the above picture, the battery category for Li-ion,dell lithium-ion battery is. The rated output voltage of 10.8V, 4400mAh charge. Some batteries also marked the manufacturers, production, normal operating temperature (0 degrees Celsius to -60 degrees Celsius), the samsung battery identification. These logos, we can view the own compaq notebook battery specifications.

 

Laptop battery loss repair method

Laptop battery loss repair method

A lot of people in the use of laptop, have lamented the laptop battery time is very short; or use after a period of time, the use of laptop time becomes short, these are caused by the notebook battery depletion, it there any way to repair the laptop battery loss it? Here what acer battery loss and how to repair laptop battery loss, the use of the books of the time becomes longer.

Battery depletion
Any apple battery (including notebooks) will have a design capacity, such as: 4800mAh, 23Wh These are the maximum capacity of said capacitor. In fact, the actual capacity did not reach so high, or after a certain period of time will become smaller and smaller, such as: the label on the battery is 4800mAh, but actually, only 4500mAh, then this intermediate is the difference between the battery loss = (4800 -4500) / 48,008,100% = 6.25%. Battery of asus depletion caused by a variety of reasons, we should be used to avoid the occurrence of the following circumstances:
1, the battery itself is of poor quality, the compaq battery loss increased use for some time.
2, the use of electrical impulse not, charging voltage and battery requirements, the current of less than sony laptop battery red power requirements
3, for a long time in the environment of high temperature or low temperature use can cause the battery loss increases
4, the replacement dell battery has remaining power protection, will start protection is generally less than 3%, but sometimes the user with a method to all of the electricity is done and then washed electricity, which is wrong.

5,Frequent incomplete charge and discharge, the battery did not run out like red to red, which also caused the power loss.
6, does not regulate the mating gateway batteries, or long-term use in the very moist conditions of the battery, the long-term use in the electromagnetic radiation to power (leading to a conductive metal in the battery)

Notebook battery loss repair method
Loss repair method of laptop battery is the most common software batteries of hp depletion charge and discharge notebooks, we can use the external monitor (as shown Master Lu). Samsung Battery there is a certain amount of loss is normal, the new notebook pen generally do not keep pushing to use, introduced me to look at how to fix the battery charge and discharge loss:

1, the most simple method:
Open My Computer – Control Panel – Power usage scenarios, full-elected time parameters using Power Options “never” and “alert” option hook removed. Unplug the power cord notebook laptop use to automatically shut down (in this process, do not let the machine standby); then connect the power charger (Do not switch the charging process), as some repeated three times, allows notebook greatest degree of Repairing laptop IBM batteries Loss.

2, the system:
a. first need to restart the laptop restart boot into the laptop’s BIOS F2-POWER (Power menu items) to enter the BIOS to enter, find the “Start Battery of toshiba Calibration” as shown This notebook power correction option, elect directly after carriage return run.

this time the screen turns blue, and prompted: plug in laptop power adapter to charge, then we follow the prompts to connect the notebook power adapter into the charging (if it is plugged prompt does not appear ); etc. power fully charged, there will be prompted to disconnect the power adapter when we run out of power automatically shutdown disconnect the power supply and other notebook.

c. wait for the laptop running out of power automatically shut down, we draw a line on the power adapter wait for power full power (this time not to boot, look at the charge indicator) after charging is complete, we turn on the computer.
At this point we do complete a battery loss repair operation, we can also with Master Lu look above the lenovo laptop battery loss and current capacity. This systems approach, if someone can not find the “Start Battery Calibration” Method 1 The easiest way to operate. In summary, the laptop battery loss fix depth of charge and discharge operation of the notebook. The notebook battery of LG depth of charge and discharge is a limit to the number of times, probably about 200 times, so we can not frequent the depth of charge and discharge operation on the books, is generally recommended once a month. More than we can hope for help.
