In the Golden Week, booking air tickets and train tickets are also very hot, Sept. 29, 30 and Oct. 4, 5, are return visitors and the travel peak.

Two days after going out like Guilin, Zhangjiajie, and so most of the popular tourist city for more than an express train has basically sell all the tickets and air passenger flow in the Golden Week will also increase, while the Golden Week from 11 a day there timing However, many of the long tour began two days from the start.

In the airport departure hall in the capital, can be seen ready to travel out of the team, a lot of tourists during Golden Week rush ahead of the trip, and now most of the departure to Europe, Japan, Hong Kong and Macao and other places from the Tour team.

Capital Airport Terminal Management Division of the Eastern running manager on duty Tan: Eleven of this year’s Golden Week holiday system is the first adjustment after the vacation, and this year, Beijing has just finished holding the Olympic Games, during the 11 passenger travel demand will be great The upgrading of the Capital Airport Golden Week passenger traffic will exceed 1,070,000 people.

The tourist hot spots in the city’s airport is expected on September 29 ushered in passenger flow peak, on the 29th day of the Capital Airport is expected to be 18 million. Chengdu Shuangliu International Airport will usher in shock after the first peak period, the Golden Week is expected to be transported more than 350,000 Chinese and foreign tourists million, unchanged from the same period last year, and basic.

For the convenience of a large number of teams to conduct security checks of passengers, some of the arrangements for the Airport Channel team. Security personnel also remind visitors, in addition to prohibit the carrying of liquid items, the ban on lighters and checked and carry fire but also to bring attention to the lithium battery.

Airport security in the capital of the Eastern Management Co., Ltd. Julei: ban on shipment of lithium batteries, carrying passengers is limited, each of the commonly used mobile phone batteries, back-up Apple battery  battery can only carry two.

In addition, the Department of Civil Aviation recommendation in the luggage of passengers hanging on a small card tied to record their names, telephone links, as well as to and from the city to prevent the luggage tag off the cases as soon as possible contact with visitors.

To deal with the coming peak of passenger flow, the major airlines were on the hot tourist city put in efforts to enhance the capacity, mainly in Hangzhou, Guilin, Hainan, Lijiang, Lhasa and other cities and tourist attractions, air routes over the load factor is expected to be 95 %.

The impact of notebook battery life - battery life did not meet expectations
 
The use of laptop computers, some factors that make the laptop battery depletion, even the longest battery can lead to the use of sub-standard time, but it does not mean that these factors will damage the battery.
 
Impact on battery life factors are:
1 factors: the speed of processors - the right to install Intel’s chipset can drive the system to use Intel’s Speed step technology for adjusting the speed of the processor, which will be an extension of the application system battery life.
Factor 2: CD, DVD, CD-RW drives and the frequency of reading - CD-ROM in an attempt to directly copy the files to the hard disk to carry out operations (including copy, delete and run applications, etc.) will increase the battery life.
3 factors: the total number of memory and memory - if the system opens a lot of applications will take up a lot of hard disk space to do the exchange of documents (virtual memory), leading to frequent hard disk to read and write, then more memory on the battery Use time more useful.
4 factors: a number of applications to run automatically in the background, the CPU load will increase, leading to reduced use of time - usually recommended when the use of some of the background to run the program shut down, only to run the necessary software applications.
Factor 5: LCD’s brightness - the lower the setting of brightness for a long time, the better battery life, you can use the FN in use or under the direction of the key key for brightness adjustment.
6 factors: Speed Step power management and set up - in the power management settings in different power scheme will affect battery life.
7 factors: battery life - the average pavilion battery life is one year, with the use of time and increase in the number of batteries used to reduce the time is normal.
8 factors: the processor and system equipment at a deeper level of application (such as DVD movies and watch 3D games) will make the batteries can be used to quickly lower the time.
9 factors: the wireless Bluetooth devices and equipment will speed up battery consumption; do not need in the wireless, FN F2 can be shut down to save power.
10 factors: the use of the environment temperature - too high or too low use of the ambient temperature will affect cell batteries in the chemical activity, thus reducing F3172A life and the life.

Jiangxi’s Xinyu College of photovoltaic materials, processing and application of technology will be on September 1 official opening. This is the first photovoltaic professional colleges and universities (F3172A , F4812A , F2024B , F2024A , F2299A , F4486B , F2098A , PP2182D ).

In recent years, China’s photovoltaic industry with 40% of the speed of development, to expand by leaps and bounds in its human resources lead to a serious shortage of supply, speed up the training of personnel has become a top priority of photovoltaic solar energy.

Xinyu City, Jiangxi Province is the first photovoltaic have a more complete industrial chain. Both photovoltaic production scale, technology level, or product quality and economic efficiency are at the forefront of domestic and international. Xinyu City, Jiangxi Province, to strive into a world-class solar photovoltaic industry base.

In October 2007, Xinyu College to the Ministry of Education of China’s colleges and universities to declare the first photovoltaic professional “photovoltaic material processing and application of technology” and approved.

Xinyu from the profession and the College of Asia’s largest manufacturers of polycrystalline silicon solar Zevi Jiangxi LDK Solar co-sponsoring high-tech companies. Two years ago, students at the school to study theory of knowledge, the third year that could be carried SinoVideo companies to study and practice. After graduation, students can independently choose to Zevi’s Jiangxi or other solar photovoltaic enterprises.

Nickel traditional phone if the laptop battery charge time is too long, nickel batteries in the liquid crystal would be to stop the Chargers will be full of electricity. As a result, in order to maximize its performance must be full of electrical discharge or on a regular basis. As for the lithium power, we can at any time at a convenient time for the lithium-ion rechargeable battery, do not need as troublesome as nickel batteries. On the life of lithium power circulating around town: lithium power can only charge at 300-500, followed by the need to be replaced.

The right to say: rechargeable lithium power and life cycle concerned the number of completed, the number of charge and is not directly related. A battery charge cycle means that all the electricity used by the space age, and then by air to a full charge. This is not a necessary and sufficient electricity.

40% of the first charge, after a period of time charge of 20%, used the next time after filling 30%, 20 %….. in the next 20% of the way, that is, just add 10% Electricity, the cumulative total to complete a charge cycle. Followed by the next cycle.

Simple to understand, for example, a lithium power in the first day only half of the electricity and then it was full of electricity. If this is also the second day, that is, with half of the charge on a total of two charge down, this can only be counted as one charge cycle, rather than two. As a result, may often go through several times to complete a charge cycle. Each to complete a charge cycle, the capacity will be less. However, the rate of reduction is very small, high-quality hp battery charge cycle many times, will still retain the original 80% of the electricity, a lot of lithium-powered electric products after 2023 as usual after use, is for this reason. Of course, life lithium power to end the need to be replaced.

Lithium battery life is generally a 300-500 charge cycles. Assuming a full discharge of electricity provided for the Q, if not to consider each charge cycle after the reduction in electricity consumption, the power of lithium in its internal life or to provide a total of 300Q-500Q to add to its power. From this we know that if each with 1 / 2 on the charge, you can charge at 600-1000; if each with 1 / 3 on the charge, you can charge at 900-1500. And so on, if the random charging, the indefinite number of times. In short, no matter how necessary and sufficient, to add a total of 300Q-500Q into electricity that is a constant. Therefore, we can also understand this: The battery life of lithium batteries and the charging of the total electricity consumption, and the number of unrelated charge. Take deep and shallow depth charge put sufficient light for the life of lithium power more or less the same.

In fact, the simple release sufficient light for the benefits of more power lithium-only products in the electric power module for the lithium to do calibration, the only deep deep release the necessary and sufficient. Therefore, the use of lithium-powered electric products do not have to rigidly adhere to the process, all to facilitate the first, charging at any time, without fear of impact on life expectancy.

Temperature not too high

If the requirement is higher than the operating temperature, that is, more than 35 ° C environment, the use of lithium batteries, Pavilion DV1000 battery  power consumption will continue to decrease, that is, the battery power supply will not be as long as usual. If such a temperature, but also for the charging device, the battery will be a greater injury. Even in a hot environment, storage batteries, the batteries will be inevitable for the quality of the resulting damage. So, as far as possible to maintain the proper operating temperature is beneficial to extend the power of lithium a good way of life.

Not too good

Li Xinhua, the same will be found to reduce the battery life, mobile phones Yuanzhuanglidian some in the low-temperature environment is not even necessary and sufficient electricity. However, do not have to worry too much, this is a temporary situation, is different from the use of high-temperature environment, once the temperature rise, the Pavilion ZV5000 battery  of heating elements, immediately prior to the resumption of electricity. Movement is life

To play the largest lithium-ion battery performance, and often need to use it, so that the power lithium-e-Status always flow. If you do not often use the power of lithium, be sure to remember a month to complete a rechargeable lithium power cycle, so a power calibration, that is, filling a deep deep release.
We must pay attention to the maintenance of cell phone batteries

A lot of friends through the Ni-MH battery and laptop battery box CRAB brands, with labels for different products for more than a match for the purchase of nickel-metal hydride batteries.

A number of domestic and foreign manufacturers continue to introduce the use of nickel-metal hydride battery of new products we have to speed up the procurement of heat, of course, her unique “quality”, such as energy density, the number of charge, a small memory effect, non-cadmium mercury and other harmful Metal advantage of a series of achievements have a nickel-metal hydride batteries in the market rising.

With everyone in the hands of the nickel-metal hydride batteries in the number of continuous increase in the use and maintenance of science gradually into the line of sight of the concern in the past. As we all know, brand Ni-MH battery life according to the official line is that the charge can be 500-1000 times, in fact this is a good value, often less than this life. But as long as a reasonable use of the charger, a more in-depth understanding of the Ni-MH battery, we can still do her “longevity.”

1. Under normal circumstances, the new nickel-metal hydride batteries contain only small amounts of electricity, we must first purchase and then charge for use. However, if the battery factory relatively short time, the electricity is enough to recommend the use of first and then charge.

2.’s Purchase of the new nickel-metal hydride batteries generally go through 3-4 times the charge and the use of performance in order to play the best, a lot of friends met for the first time charge of the minor problems, such as charging for the first time after the shooting did not imagine the amount of PP You so much? In the 3-4 times charger and use after all be solved.

3. Although the Ni-MH hp battery memory effect of the small, we still recommend the use of as much as possible every time after the end charge and is full of one-time, I will not be sufficient for a moment and then charge. However, this “longevity” Oh, that’s important.

4. Rechargeable battery, charger should pay attention to the surrounding heat, too deliberate what the fan is no need to blow, but bearing in mind that the charger is not to put too much around the debris. Ordinary users in the use of batteries, the batteries are not the exclusive use of storage bag; users to replace the battery after the customary battery placed at random, regardless of whether or not the release of the place clean, damp. The consequences of such a battery is easy to dirty and easy contact with the metal such as  , and other key contacts easily damp, and these are the enemy of batteries. : Users should set up a special cell to place, maintain and clean the battery. In order to avoid problems such as loss of electricity to keep the battery at both ends of the contact point and the internal battery lid clean and, if necessary, use a soft, clean dry cloth graze.

5. Not for a long time, remember that the battery cell from the warehouse out, under dry conditions recommended card into the Pavilion DV4000 battery  box, to avoid short-circuit the battery.

6.’s Not a long-term nickel-metal hydride batteries will be stored in a few months later, the battery into the nature of a “dormant” status, significantly reduce battery life. If the Ni-MH battery has been placed for a long time, I suggest you first slow to carry out sufficient charge is appropriate. Here is another key issue involved: Ni-MH battery, the battery is fully discharged and then save, or save live? These two very different point of view, it should be adopted? Many people believe should be the former, but I think a more reasonable to preserve the battery charged. Because: It has been tested, Ni-MH battery to preserve the best condition that charged about 80% of preservation. This is because Ni-MH battery self-discharge of a larger (10% -15% in a month or so), if the battery completely discharge and then preserved for a long time not to use, the battery self-discharge phenomenon will result in excessive discharge of the battery, Will damage the battery. Do not believe it? What do you think of buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. : More compared to rectify the wrong point of view, from the start in the right direction maintenance batteries, or else they will backfire.

7. Have made many friends in the post asked how the Ni-MH conduct discharge? The expert asked about the number of batteries, reached the same conclusion to remind friends. Do not try to nickel-metal hydride batteries, rechargeable lead-off put the failure to do so against much larger than their own Ni-MH battery memory effect!

8. Multimeter battery is full of self-test or not. General in charge Ni-MH battery, 1.2V voltage below the normal voltage in full after about 1.4V. We judge this, it is easy to judge the status of the Presario V2000 battery .

9. Charger can be broadly divided into fast and slow-filling charge. Slow flow of small charge, usually around 200mA, such as our common charge current is 160mA or so. Her charge for a long time and charging the 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but the charge would be sufficient enough and did not hurt the battery. Fast flow usually charge more than 400mA, charging significantly reduce a lot of time ,3-4 hours you can get, and everyone’s favorite to win. Many types of fast filling, the prices vary. So often we all have doubts, are filling fast, and why the price is a big gap in it? Good charger in particular are filling fast with a good anti-over-charge protection, for example, we the Panasonic common charger Need BQ 390 in this regard was especially outstanding, excellent software, chip design capabilities in the battery charge, Also quick to charge the battery for damage to a minimum.

10. There is such a conflict: Slow injury is not sufficient battery charge time is too long, however; fast charge time can be saved, but the batteries have hurt, even if the world is the best surface of the Need for Panasonic BQ390 charger can only be good to reduce the extent of injury , But can not be completely avoided. This contradiction can be resolved is to buy a quick charge and a charge slowly. With sufficient speed and sufficient period of time, for example, at 5, 10, Chong Chongdian slow to switch to one or two. This will also return to the performance of battery-top condition.

11. Batteries are generally used battery, that is, 4 or 6 series, this time to maintain the balance of each cell is very important, otherwise, because of a battery problem affected the entire battery pack. First of all, to ensure that the battery capacity, the best choice of the same brand of the same type of battery at the same time to buy. Then, to keep the internal battery power, said simply, is that the Armada E500 battery  power is either full or empty. If there are more cell group composed of a number of batteries, you can try to “select” look. That is specific to capacity, similar to parameters such as voltage battery series into a single set of batteries, due to inadequate conditions, under normal circumstances, let us test after the end point of voltage and power good voltage washed it.

12. To talk about the final charge and discharge.

The high-grade NI-MH battery charger using a detection-DELTA V battery voltage to determine whether the battery is full. When the battery voltage discharge curve and a little bit similar to the beginning of a more rapid rise, followed by the slow rise until sufficient good, fast start and voltage drop in the rate of decline is not great. Before commonly used nickel-cadmium batteries are also similar, but the decline in the speed and range than the NI-MH are great. The largest number of chargers on the market (that’s less expensive) is often used in value-charge pressure, such as Po-old GP is the 1.4V charge voltage value, that is, into the battery when the 1.4V voltage in the absence of the poor, charging the end of . Such an outcome is often not the battery is full, especially compared with some of the old battery, due to increasing resistance, the real increase in battery on a lower voltage. This charger current and often smaller, often have to charge more than 10 hours. The use-DELTA V automatic cut off of the charger, because it can accurately control the charging time, it can be more reliable to use the current charge. Current nickel-metal hydride rechargeable batteries for the damage we did not imagine the stakes, the opposite, the use of DC now, more high-current charge. First of all, is a matter of time, do not have to speak. Then, Ni-MH Armada M700 battery  has a characteristic that you charge the greater the current, it can release the greater the current, DC power is a tiger, not a small current, relatively speaking, therefore, the use of relatively large Current charge is a wise choice, can increase battery _ clean. 5, the general charge current should not exceed 1.5C, C for the battery capacity is 1000MAH batteries, not more than 1.5A. I normally charge for use of 0.5C (my current adjustable charger). Discharge, under normal circumstances, DC after the black screen will be able to take charge of, NI-MH little memory effect. But after a period of time, as well as to balance the battery cell activation, to control the discharge of the battery voltage termination. NI-MH battery voltage of the termination of 0.9V, the discharge time careful not to over-discharge, on each battery 0.9V when you can stop the discharge. NI-MH battery has not tough nickel-cadmium batteries, the charge had been released and are more sensitive to high temperatures. Charge-discharge temperature. In general, do not let the battery temperature higher than 45 degrees. The battery is full, the batteries will be fever, a high current when the temperature should be about 42 degrees and not more than 45 degrees, otherwise life will quickly reduce the battery internal resistance will increase. In addition, the battery charge after a high temperature, cooling, and so only after their charge, the money would also charge the battery cooling, and so on. Not long after the re-use, the best sufficient to reactivate the Armada V300 battery  release several times. The use of normal time to pay attention to maintaining the integrity of packaging paper, there can not be broken in order to avoid a short circuit. Not tempering the impact of the battery, do not fire, and so on.

However, despite the use of laptop computers, high temperatures will bring damage to the battery. However, the laptop battery removed, only the use of fixed power, there will still be some danger that dust and moisture will cause some damage to the battery, and laptop computers in order to avoid the use of the environment for all of a sudden power notebook computers may be caused by injury, so In general, manufacturers are warning users not to remove the battery. Of course, such a result can imagine the natural, often because of your battery in such a relatively poor business environment, it will not be long over, then you need to repair the new center to replace the battery, then the benefit The manufacturer is a natural.

Finally, an eye-catching is the focal point of lithium batteries how reasonable charge and discharge the problem. The lithium battery is carried out for the best part of the discharge, rather than fully discharged, and as much as possible to avoid the often complete discharge. Often the battery too low discharge of the battery so that the results can only be scrapped in advance, because if the battery on each unit below 2.5 volts, the battery’s internal safety circuit will be switched on, this time of the powerbook battery would be some bad spent. Therefore, in order to avoid the occurrence of such cases, not to save battery power before it’s too completely, but should be stored until a number of electric charge, and again prior to the first full use of electricity.

All in all, in order not to make your battery’s too early to lose, so in normal use, you should try to abide by the following principles:

A. avoid full discharge, and often for lithium batteries. The repeated and arbitrary charging of the lithium battery damage is very small, almost negligible.
B. will need to be set aside to preserve the lithium batteries under the shade, remember not to put the refrigerator. Avoid high temperature on the car, such as long preservation, the Latitude D600 battery  will charge to 40% after the placement.
C. If you do most of the time in the use of fixed power, remove the batteries placed in the shade.
D. no need to purchase spare lithium batteries for storage, so this is actually a waste of battery.

The Latitude D500 battery  is used to use, as long as attention to the reasonable use and custody of the way, there is no need for excessive care, it’s as much as possible for it to contribute more masters of the performance is what matters.

Misunderstanding one: buy a notebook computer to come back again need to charge and discharge three times in order to activate the laptop battery.

Unless you buy a notebook computer inventory is more than one year, otherwise we will not need to do so, because the batteries in the battery when the factory has been activated, and the batteries in the package into a notebook’s battery time and after a Equivalent to the activation of the test, so you get the battery in hand, has long been activated before, three times longer charge-discharge process is unnecessary to increase the battery wear and tear.

Second misunderstanding: the first charge must be sufficient enough for 12 hours

For those who do not have this early battery control circuit of the Ni-MH battery model is applicable, but now has a smart charge-discharge control circuit for the notebook battery is a joke, when a notebook computer batteries, the charge current will be automatically cut off , Even if you continue to charge 120 hours, there will not be any change in the state, generally speaking, even if the charge of the slowest machines, 6 hours completely filled, the rest of the “charge” is just a waste of their time. It is time to get the new machines should first get a rechargeable power shine.

Misunderstanding three: the need for regular inspiron battery of correction, once a month put the total charge.

The memory effect of a strong Ni-MH battery, which is an essential task, but lithium batteries, the cycle is too frequent, and lithium batteries did not completely eliminate memory effect, but has been greatly reduced memory effect, if you use the battery is Frequently, you should discharge the battery to the relatively low (about 10 ~ 15%) rechargeable, but that even if the discharge machines are not open (0 to 1%), belonging to the Li-ion battery for a greater depth of the injury discharge Generally speaking every 2 months to do so once the operation of it. If you use very little battery, so long as every three months the first time this operation can be had.

Four errors: can be calibrated to enhance the capacity of the battery

The so-called correction, when the actual capacity of the battery and control circuit record is not the same capacity, on a battery charge and discharge depth of the operation, so that the control circuit record, so that the battery close to the actual situation, this is a true performance of the battery capacity The operation rather than enhance the capacity of the key factors here is the actual capacity of the battery if the battery’s actual capacity than the control circuit in the capacity to a record high, correction can be made to increase the capacity of the Latitude C600 battery  looks, if the battery’s actual capacity than the control circuits The capacity to a record low, the correction will reduce the capacity of the battery looks, which is many people over the effect of correction of the reasons, keep in mind is correct batteries to show the true capacity, the elimination of battery and control circuit between the Bias, as demonstrated by the capacity will increase or decrease, this is the battery itself, rather than the state of your correction by the decision. Correction is likely because the battery discharge when the depth of injury, but capacity has been falling.

Many battery manufacturers to provide for the correction procedure, and BIOS version of the Windows version, it is best to use these procedures to correct, Windows version can be on the side of the work carried out on the side, BIOS version will not be able to do.

Five errors: compatible charger can also use the

The notebook computer power consumption is much larger than cell phones, the most extreme cases, the need for power supply and battery charging equipment to meet the requirements of the power supply to run at full speed, notebook computers generally not compatible charger, as the various models of voltage, current, or even Interface is different, common to a variety of notebooks in the “charger compatible” than the original but also your charger, even if the interface is the same as if the voltage and current below the nominal value of machinery, machine work at full speed when the Latitude CPX battery  May not be able to obtain sufficient charge current, battery This is a lot of damage. If the voltage and current much lower than the nominal value, or even can not find or be able to boot can not start charging, the power to choose when to choose the best and the same as the original, it can not be found, please note that a certain voltage and current To be in line with the nominal value of machinery, plant with the same general interface of different products, but may be different voltages and currents, which must pay attention!

Six errors: the need batteries fully charged (or put photo) to preserve

Whether it is full or shine, in fact, are not true, let a long-term preservation of photoelectric batteries will lose their activity and even lead to the control circuit protection and self-locking no longer be able to use the full power will bring long-term preservation of the security problems, the most The ideal of preserve is about 40% of discharge to the preservation and then, afraid of lithium batteries and high-temperature and humid, it should be placed in a cool dry place to preserve, but the temperature not too low, or capacity will be greatly reduced, about 20 degrees or so is ideal Preservation temperature.

Seven errors: Latitude CPi battery  dying, but also for their own batteries

The battery is a lot of people for such a deadly, manufacturers seem to expect someone to do so long ago, many brands of notebook batteries are designed self-locking function that once the batteries out of control circuit, the circuit will enter the self-locking, Only the use of specific means can be answered, before that the control circuit will not work, that is to say the same end-of-life battery, battery notebook batteries can not change the dry-cell batteries, if you do not have to change batteries, please remember to find specialized The battery maintenance company to wield the sword, its own waste for just a small, the kind of effort after the failure of the depressed and depressing is the worst.

Eight errors: 99% after the charge has been less than 100%, continue to be sufficient explosion

Notebook battery exploded almost no opportunity to, at most issue a high fever caused by melting shell, but rarely lead to open flame, was released a few incidents, the fact is that when the production of non-performing technology, in use lead to short-circuit caused by, even if Most of this will be short-circuit the Latitude D800 battery  protection circuit in the circuit will not disconnect the greater the damage, except in the protection of the circuit before the batteries short-circuit (before COMPAQ notebook computer batteries should be time for the explosion is caused by), Such a thing in my notebook of a large number of contacts three years ago, have only seen two cases. Instead, the phone is in such a lot of things, in the final analysis, or the quality of the battery problem, a large number of poor-quality cell phone battery assembly, the notebook computer and almost never sell this kind of battery, for which no models have a large amount of worth Compatible with the production of batteries.

The reason to charge less than 99% after 100%, often because the battery control circuit record and the battery itself, the deviation of the state, the battery has not reached a record in the control circuit voltage, the power control circuit has been charging, the battery in fact Has been replete with such problems can usually be corrected through the resolve, but even if there is no correction has nothing to do, because most of the circuit will be in charge for a long time can not be filled automatically disconnected after, or even intelligent automatic current record of 100 set 99% %, Even if it has been a fool’s design, but also because of the current very small at this time without causing injury.

The current notebook computer batteries are basically the temperature detection circuit, when the Latitude D600 battery  temperature is too high, most of the control circuit will be forced off the battery to prevent further temperature rise, so this kind of charge to the explosion in notebook computer batteries occurred No less chance of the first prize in the lottery.

     If you do the maintenance is in place, use a battery to a week basis, in about a year later still 60% to 70% of the capacity of my battery is probably the case, if indeed that looked increasingly haggard battery You are on the kind of torture, the best way is to get down and do not have to, and not to pray or Tidiao power plug, or buy more as a back-up, as long as batteries and a notebook in order to bring enough value to be happy, I would like to Their sacrifice is worth it.

 laptop battery   life and the life cycle is usually divided into two Floating Life. The battery capacity to reduce the value of the provisions before the battery charge and discharge cycles as the cycle of life. In the maintenance of normal conditions, the Floating battery-powered, known as the Floating Life. Generally maintenance-free lead-acid battery life of up to the Floating over 10 years.

Usually two to complete the task, first and foremost as soon as possible so that the resumption of the rated capacity of the  Business Notebook nx7400 battery  and the other task is to add trickle charge the battery self-discharge as a result of the loss of electricity in order to maintain the battery’s rated capacity. In the charging process, lead-acid battery anode plate of lead acid gradually into a lead, sulfuric acid of the cathode-board lead gradually to lead dioxide. When the anode is on the board of sulfuric acid into a completely lead and lead dioxide lead after the battery to start charging reaction occurred, producing hydrogen and oxygen. In this way, non-sealed lead-acid batteries, the electrolyte in the water will be gradually reduced. In the sealed lead-acid battery, using the middle rate of charge when hydrogen and oxygen to the water for re-combination.

Time and the initial charge related to the rate. When the charging rate of more than C / 5, the battery capacity back to 80% of the capacity released before the beginning of that charge-off reaction, as shown in right. Only charge less than the rate of C/100, can the battery capacity back to 100% before the beginning of charging excessive reaction. It also can be seen by the right, the more charge rate, in order to make the Pavilion dv9500 battery back to 100 percent of capacity, must be allowed to have a certain degree of charge, charge-off reaction occurred, single-cell battery voltage of the rapid rise up to a certain value, Reduce the rate of rise, and then the battery voltage slowly began to decline. This shows that the battery fully charged, the battery capacity to maintain the best way is to join both ends of the battery pack is a constant pressure. In other words, adequate electric battery, charger should be a constant output voltage of the Floating. Floating in the state, the current charge into the battery should be able to add the battery self-discharge as a result of the loss of electricity. Floating voltage can not be too high so as to avoid serious charge-off and shorten battery life. Proper use of voltage Floating, maintenance-free lead-acid battery life of up to the Floating over 10 years. Practice has proved that the actual voltage Floating Floating with the provisions of the voltage difference of 5%, maintenance-free battery life will be shortened by half.

The PCG-FR415B  voltage and temperature are closely related, each temperature rise 1 ℃, single-cell battery voltage to drop 4mV. In other words, lead-acid battery voltage with a negative temperature coefficient, the value-4mV / ℃. It can be seen that in 25 ℃ ambient temperature for the work when the charger is ideal when the temperature dropped to 0 ℃, the battery will not be sufficient electricity, when the temperature rose to 50 ℃, the battery will have a serious charge and to shorten Life. Therefore, in order to guarantee a wide temperature range, so that the battery can be just enough electricity, the Chargers various voltage conversion must be with the battery voltage and temperature coefficient of change.

For the first time the use of batteries, three times before the need to charge 12 hours?

This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the laptop battery reached saturation, the control circuit will automatically switch to the open state, so even if the charge is a long time to no avail.

In order to prevent the memory effect, should it run out of electric charge it?

Every time charge of battery discharge before it is not necessary, but also harmful, as they had proved the depth of discharge the battery life will reduce unnecessary, when the proposal to use about 10% of the battery can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.

Insert AC, the battery should be to win in order to prevent repeated charge and discharge it?

I suggest that is: do not have to. You might get lithium-ion battery discharge natural to refute me, saying that if the natural discharge after the ibm battery if there is access to power will be reduced by repeatedly charging and discharging of the battery life. I give you a “no” answer to the following reasons:

1. Notebooks now have the power control circuit design of the features: When the battery is 90% (as most of the HP models) or 95% of the charge will be, and to achieve this through the natural discharge capacity of 2 hours a week , I would say when the batteries do not have to idle for about a month to complete in order to maintain the battery charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charge;

2. Even if the battery “unfortunate” was once again charge, the loss will not be brought about by the long period of time than the battery consumption caused by the large decline in the number.
3. Your data than you or your notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.

Long-term need to preserve ThinkPad T60 battery  power is full of it?

Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)

Storage temperature of 40% of the state-of-charge 100% state of charge

0 degrees 98% (after one year) 94% (after one year)

25 degrees 96% (after one year) 80% (after one year)

40 degrees 85% (after one year) 65% (after one year)

60 degrees 75% (after one year) 60% (3 months)

It is clear that if the long-term preservation of the battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the ideal, of course, should be the best month to come up with a battery that can ensure a good save battery , Also would not let the loss of full electricity and cell damage.

As far as possible in how to use the notebook to extend the use of time?

1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time;

2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the ThinkPad T20 battery  life;

3. The use of hard disk drive and the deceleration of the software. If NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the power consumption of notebook;

4. Make the best use of standby, sleep and other functions. When a longer period of time do not have a computer that allows notebook standby or hibernation, both to save power and extend the service life of the computer. Battery on the controversy continued, if readers have any objection to the Forum SUNDIGI.COM question, let us discuss this topic in the debate.

Notebook battery charging algorithm and the number of ordinary DV mobile phone battery charging algorithm is the number of different
According to the notebook’s laptop battery Practice
Charge does not mean that you plug in the number of filling a number of electric power
Charging the number of relatively complete name should be called - full battery charge volume of the number of
Is basically in accordance with the battery power into the battery’s charge to calculate the number and degree of aging

Counting methods are as follows:
In general, when the battery charge is greater than the current start-up electricity consumption reached 70% (the value of different companies have different requirements, generally will not Chaitai Duo)
When the battery power input than the current total of over 70% of the amount of charge, as a charge.
For example, your ibm battery limits of the value is 70%; every time you put in 80% of the battery charge time, you can read the battery out of the number of battery charge for each additional one, the actual number is charging 4 times.

Lower than the initial capacity of the battery, a total input power = full power - the power of the current time, as a charge.

At present, full power: As the batteries are aging, so there is an internal battery aging algorithm automatically based on the use of the battery automatically update the current full battery charge money to prevent the charge-off caused by insecurity.
The algorithm, depending on the batch of batteries, companies, manufacturers vary. Some simply use the ThinkPad T60 battery  cell security chip manufacturers to set the default method.
