South Korea on a number of large enterprises plan to the year 2008 to develop a joint 371785-001 communications equipment of the fuel cell with international standards, unity and security of the base fuel components, so that the fuel cell’s  m8511 low-cost production possible.

According to the “Japanese Economic News,” reported the other day, with the exception of Japan, Toshiba, Hitachi, NEC, Samsung Electronics of Korea and the United States engaged in the development of fuel cell company MTI, a number of other pa3384u-1brs communications companies and fuel cell companies will also participate in the standards.

The standard is expected to become the International Electrotechnical Commission’s series of international standards has become the PCGA-BP71 de facto industry standard.

At present, a lot of e-business is an independent fuel cell trial, the manufacturing cost of lithium batteries is generally a few times. They hope that the adoption of unified standards, sharing design-related, but also receive bulk supply of parts and components in order to reduce the cost of production.

How to correctly to the cell phone lithium laptop battery problems has been a good deal of readers called or wrote to a friend asked how correctly to the cell phone lithium battery, it seems this is a problem we all more concerned about the issue, I would like to focus on will answer this question: to buy a new cell phone lithium battery charging three times before How long will it take? A lot of friends that the charge should be 12 to 14 hours in order to activate dormant cells in many businesses in the same is true when consumers purchase said. In fact, this issue does not have a conclusion, while I personally think that there is no scientific basis in fact three times before and after the charge is the same charge, there are 3 to 4 hours is sufficient. First, we all know that when over-charging lithium batteries, over-charge or discharge, excessive discharge current when the battery life and have a great capacity for damage, and may even cause an explosion or deformation of the battery, so it is in the internal lithium battery Have set up electronic circuitry to protect the batteries. When the battery over-charging, over-discharge current is too large, will be cut off connections with the outside. Like some friends, as reflected in: cell phone charger in the boot, the phone has come in automatic shutdown will cause problems. In other words, the initial battery charging, low voltage, and when a call came in, the phone to ring, it is necessary to maintain a certain degree of power. In the low-voltage, battery current will increase, too much current caused by the battery protection circuit moves to cut off the battery connections with the outside, resulting in cell phones turned off automatically. Second, to enhance the efficiency of the rechargeable, lithium battery to first-current electricity to the current charge of 90%, battery voltage of 4.2V, it almost takes about 2 hours; and then to a small voltage current charge until after the battery is fully charged Internal circuit protection movement, which takes about half an hour, taking into account the hp battery, the charger Products of individual differences, rechargeable lithium battery with 3 to 4 hours is appropriate. For example, I tested the battery charging process, Siemens 6618: 0.5 hour rechargeable battery power consumption to 50%, shows that “565F Battery”; charge 1 hour, the battery up to 80%, indicating “8667 Battery”; charge 2 hours, the battery 100%, indicating “A667 Battery”. Taking into account the margin of error showed that power mobile phones and other factors that may charge additional 1.5 hours. There is one more point it should be noted that lithium batteries do not have to be punished by placing the long-term hibernation state, the normal need for the use of pre-activated. After a general 3 to 5 charge, discharge cycles can be activated. According to the first two reasons, we can see that the dormancy of lithium batteries expect for a long time to activate the charge is meaningless. Because the battery is full (after about 2 to 4 hours), lithium battery protection circuit has been on the move, to cut off the external power supply. Due to the protection of the circuit, rechargeable lithium power for a long time although no harm, but to protect the circuit will start the consumption of energy batteries, circuit protection in case the loss of role, ranging from cell damage, while heavy damage to the cell phone, and then the consequences are afraid to re-envisaged . Therefore, taking into account the mobile phone, lithium battery charger and individual differences, charging three times before and after the charge are the same, only 3 to 4 hours has been a good deal of readers called or wrote to a friend asked how to correctly The cell phone lithium battery, it seems this is a problem we all are more concerned, I would like to focus on will answer this question: to buy a new cell phone lithium battery charging three times before How long will it take? A lot of friends that the charge should be 12 to 14 hours in order to activate dormant cells in many businesses in the same is true when consumers purchase said. In fact, this issue does not have a conclusion, while I personally think that there is no scientific basis in fact three times before and after the charge is the same charge, there are 3 to 4 hours is sufficient. First, we all know that when over-charging lithium batteries, over-charge or discharge, excessive discharge current when the F2024B  life and have a great capacity for damage, and may even cause an explosion or deformation of the battery, so it is in the internal lithium battery Have set up electronic circuitry to protect the batteries. When the battery over-charging, over-discharge current is too large, will be cut off connections with the outside.

After a general 3 to 5 charge, discharge cycles can be activated. According to the first two reasons, we can see that the dormancy of lithium batteries expect for a long time to activate the charge is meaningless. Because the battery is full (after about 2 to 4 hours), lithium F2299A  protection circuit has been on the move, to cut off the external power supply. Due to the protection of the circuit, rechargeable lithium power for a long time although no harm, but to protect the circuit will start the consumption of energy batteries, circuit protection in case the loss of role, ranging from cell damage, while heavy damage to the cell phone, and then the consequences are afraid to re-envisaged . Therefore, taking into account the mobile phone, lithium battery charger and individual differences, charging three times before and after the charge are the same, only 3 to 4 hours.

On the theory, storage batteries have always had the energy loss. The battery itself, the inherent structure of the electrochemical laptop battery   capacity determines the inevitable loss was mainly due to self-discharge. Usually self-discharge and the size of the cathode material in the electrolyte and its solubility in the heat after the instability (easy to self-decomposition). The rechargeable battery self-discharge than a high battery. And different types of batteries, the battery self-discharge rate per month is not the same. In general 10-35% of the variable. A  ThinkPad R60 battery  self-discharge obviously much lower, at room temperature does not exceed 2% per year, storage and in the process of self-discharge is associated with increased resistance  Inspiron 6400 battery , which can cause the battery to reduce power load, and in the discharge current larger , The energy loss is very obvious changes, following table lists the normal storage conditions, the self-discharge approximation:

Self-discharge type alkaline manganese batteries MnO2/Zn round 2% zinc carbon battery MnO2/Zn round <4%

Lithium-ion batteries and lithium MnO2 circular button Asus battery  about 1% of the Ni-Cd / Ni-MH battery <35%

The rechargeable laptop battery charge issue has been the focus of concern, the right of charging a good way to ensure that the battery life
Life. Rechargeable battery charging method recommended by the variety of different methods of charging for the line of chargers have different
Requirements of the natural impact on the cost.
Memory effect of rechargeable batteries is a natural enemy, it is generally believed that the long-term lead to incorrect charge, and it can make electricity
Chi premature. Memory effect can not be effective battery charge, appeared on a full charge, with one on the end. To prevent
Battery memory effect is to ensure that the battery \ “adequate shine \”, in other words, before the charge will be the best
Brightness remaining battery power, a charge should be sufficient. Nickel-cadmium batteries are usually prone to memory effect, the charge
Should pay special attention to electricity, Ni-MH battery in theory no memory effect, but also to follow the best \ “adequate shine \”,
This is a lot of discharge charger to provide additional features. For the memory effect due to the emergence of capacity, then drop
The batteries, we can no longer sufficient one-time shine of a one-time method of repeated several times, most of the batteries can be
To be repaired. Shelved for some time, the loss of cell activity can try to use the impact of the current test methods
Figure hit live.
Battery charge current and charge time for the relationship between the capacity of the inspiron battery charge current to be divided by the charging time, taking charge-off
In the way of wear and tear, so the charge will be calculated by multiplying the result by 1.2 times this constant.
For nickel-cadmium and nickel metal hydride batteries most commonly used method is to use a simple charge 10% C constant current charge, also known as the \ “slow charge \”
, That is, in accordance with the current capacity of 10% of the value of charge current to determine, if a section of the nominal capacity 500mAH battery, and its recommendations
For the charge current 50MA; Another example is a nominal capacity of 1300mAH battery, and its recommendations for the charge current 130MA. In the
The current charge for the next 12-15 hours will be able to do as full. Although the current recommended charge but does not require strict
, To allow greater fluctuations in current, so in accordance with this method produced by the structure of the charger is very simple, just a general
220V power will be converted to the appropriate city’s low-voltage transformers for the rectifier diodes, for limiting the resistance as well as some fat
Second-ray machine, such as direct control devices, the cost is very low, the vast majority of the market independent of conventional chargers used in this way,
More than just a different shape. \ “Slow charge \” is a relatively simple one but a necessary and sufficient electricity to wait for more than 10 hours, it
In some impatient people. Battery manufacturers also allow users to an urgent need to use the current 30% C for 4-5 hours of Latitude CPX battery  charging,
Referred to as \ “fast charge \”, but does not recommend used, in theory, have the battery on a minor injury. So most of the conventional charge
Electrical appliances are \ “fast charge \” and \ “slow charge \” two respectively, and recommended that users \ “slow charge \.”
In many cases, users need batteries fast, effective and safe charge, fast charge on the need to use more
Current. Rechargeable battery in the current process, there will be polarization effects, so that the battery fever, and when high-current electrical charge
After the tank is full, if not stopped in time, the battery will quickly fever, severe cases can lead to the battery exploded and burned. So
Require rapid charger with a self-stop function, but also address the effects of polarization, so that charge high security. As early as
Period of rapid charger, using a simple charge from time to time, but such targeted charger, the charging effect is not

And other high-end electrical appliances and communications equipment.
Now the market many types of rechargeable batteries, only 5 of the Latitude C600 battery , for example, have the capacity 500MAH, 600MAH, 700MAH,
850MHA, 1200MAH, 1300MAH, and so on. From the top 10% C \ “slow charge \” We can understand the principle that different capacity

For more than 1000mAH rechargeable Ni-MH battery charger can try to use ordinary fast charge file, which file more current,
Multimeter measured by the actual charge current, if the value close to the nickel-metal hydride rechargeable batteries require 10% C of the charge current is on the side

Cell phone chargers and brand manufacturers can not be said to be a breakdown of some of the quality of the product really is nothing to boast about people. Sometimes not only the laptop battery charge can not be dissatisfied with the green light, low-quality batteries and chargers for mobile phones is also great harm. The following lists the author charger (mainly non-original products supporting) the purchase of properties and pay attention to:

1. Wall Décor & Hangings be able to identify good quality lithium batteries and nickel-metal hydride battery, and then decided to charge mode (Li-ion battery protection circuit board has an integrated circuit storage of information on the characteristics of lithium batteries, on the one hand, so that it can identify Wall Décor & Hangings lithium batteries, To determine the “current set” and “voltage” charging mode; On the other hand, can identify the cell phone lithium battery to discharge the way and decided to call a state).

2. Ni-MH battery charging mode “set current.” Ni-MH battery is charging too afraid, too, when Ni-MH battery charge when the reverse reaction would be to prevent the excessive rise in voltage, the battery will react a little fever. In addition, Ni-MH battery plus there is usually a thermistor in order to prevent over-charging the inspiron battery. At present, most of the mobile phone operating voltage is 3.6V or so, it takes 3 Ni-MH battery core. The general core Ni-MH battery charge-off to about 1.4-1.5V that is about to stop, the 3 Supreme battery voltage of about 4.4V.

3. As the battery lithium-off charge will be dangerous and for charging and discharging of the conditions set than the nickel-cadmium batteries and nickel-metal hydride batteries must be harsh. Additional internal lithium batteries are usually a control board in order to prevent excessive charging. According to the characteristics of lithium battery design, the first paragraph of the charge is based on “current fixed” charge, fast charge until full time again in order to “set voltage” (between 4.1-4.2V) rechargeable batteries so that the way to achieve the best condition. Wall Décor & Hangings some jerry-building on the market, to identify all cell phone batteries into nickel-metal hydride batteries, and the “current fixed” charge, often easily lead to over-charging lithium battery. Good quality of the protection of the board at this time will be the protection of lithium batteries, chargers continue to prevent the charge. If the encounter of the poor design of circuit boards, not only unable to protect the battery, resulting in over-charging the battery, may also lead to over-charging the battery core deformation, leakage and explosion and so on.

4. On the market, most Wall Décor & Hangings fast charge, generally 3-4 hours have been covered. Wall Décor & Hangings charge when the show finished, even if it does not remove the battery from Wall Décor & Hangings, and only a very weak power into the Latitude CPi battery .

5. Ni-MH battery memory effect is not large, often do not discharge, lithium batteries are not the basic discharge. Sales of the charger on the market, the devices attached to the discharge of variable quality. Have been the poor quality of the discharge, cause internal battery anode plate corrosion (Ni-MH battery’s internal electrolyte is alkaline potassium hydroxide solution), and reduce battery life and can be used in normal capacity. In this case, the discharge each time before re-charging, bad battery will be faster. Under normal circumstances, so long as an electric battery used to automatically shut down after charging, the battery is the best method of dealing with discharge.

6. Charger made the most of the block have been sufficient or under-charging, the need to be cautious in choosing. For example, run out of battery power to re-charge, only a half-hour show on the completion of charge. However, measuring the voltage is still very low, the Latitude CPX battery  will be removed from the Wall Décor & Hangings Add another can continue to charge.

1, the first laptop battery charger to charge more for a long time?

The new battery to charge more for a long time in order to “activate” the battery is not completely correct. Battery into bought a new mobile phone use on several straight necessary and sufficient to achieve full or close to the nominal capacity. The time is rechargeable battery and the capacity of the charge and the charge from the current income. But the proposal to buy a new battery to run out of power before the 3rd in cell phone use on the original charge directly to the battery fully charged, the general standard of time is an indication that the state is also full of cell phones to stay in charge more than 2 hours, as much as possible to activate the battery The largest electricity.

2, charging several forms of contrast:

Direct filling (filling lines) are safe and reliable way of a charge, no adverse impact on asus  battery life. On the phone because the charge control circuit will ensure that sufficient, however; but charging time is too long may lead to cell phone fever, may affect the life span of cell phones; charge mobile phones, once the battery problems, such as the use of poor-quality batteries appear drums, and explosions, leakage The explosion is bound to have a cell phone to the irreparable physical damage.

Wall Décor & Hangings, to the use of mobile phones in a specific period of time, the other to a rechargeable battery used. The need to connect the original charger (line charge), is the most secure and reliable way, because the charge current regulator on the line to complete the charge, avoid the high voltage of the battery damage. At the same time, because the battery is charging and cellular phones to carry out the separation, batteries without any problems, the phone will not have an impact.

Travel and filling filling panacea, the general is not recommended. Travel as a panacea and sufficient charge by virtue of a simple circuit to achieve the necessary and sufficient lines of the function, the function of Wall Décor & Hangings at the same time, pressure had been sufficient to protect it is very difficult. Inaccurate charge control, would be very easy on the battery charge-off, such as travel charge that applies to E680, in the saturated green climate, sustained a half-day charge, the battery voltage will be more than 4.25v, when the high reached 4.29v. Battery has been in charge of the cases, it can cause internal battery chemical changes, such as dendritic produce, pierced cell membrane of the SED, leading to short-circuit the M2 battery  expansion: Lvke batteries through the mouth leakage-proof; Steel Shell batteries without proof I will be drastically increased, and Bombings only to release energy.
On the other hand, the poor quality of the use of low-power components, but the output current overload, overload devices, heat might have caused open flame burning, especially at night, less power consumption, high voltage electricity, poor quality of travel and charge Wall Décor & Hangings likely to go wrong.

3, to determine how the charger is full of batteries
When the battery voltage 4.1v-4.2v, a M2000 battery  charger will be judged, and then the charger saturated green light, we can win this time of the battery.

shengbangwei  (SGMICRO) latest two-cell program, used to work long hours to meet the demand for digital products, the market has improved the existing two-cell deficiencies in the program can be widely used in cell phones, GPS, PDA, PMP such as digital electronic products or laptop battery .

The program is divided into four functional units, the laptop battery discharge feature interlocking unit, the battery voltage detection (with software) unit, the main vice unit battery charge each other, together with the software with hardware control unit.

The program after testing the system, the digital power supply products, power, switching, testing done to verify a complete, detailed circuit parameters to St. microelectronic technology sector advisory states. If the attached map-related test, the temperature range to meet the expansion of the industry-standard -40 ° C to 85 ° C.

First of all, get a piece of new batteries, a lot of users is in accordance with the practice of business tips in the lithium batteries used in the previous three charging even more than 12 hours. In this debate there are many on-line, but I found that in actual use, in fact, the majority of the notebook laptop battery is not necessary. Why? Merchant said that in order to fully activate the cell’s activity is entirely new wake-up battery. For this reason it sounds very full and credible, but we have not thought about this issue. If, notebook battery manufacturers have not yet been fully activated on the play, so the product can be said that only a semi-finished products. Can not require each user to master the skills to activate the battery, it is impossible in reality. As a result, the battery factory has been a manufacturer of a fully activated. How are users to charge the battery for 12 hours in favor of the use of it? Here the author gives a negative answer, the current notebook batteries have improved power management circuits and charging management system, when the battery reached saturation, the control circuit automatically switch to short-circuit, it is only after time in a waste of time Only. How can activate the battery of this activity? In fact, the manufacturer of the battery is activated in the absence of overload protection of the battery will discharge and recharge for a long time. Therefore, charging three times before the 12 hours is not necessary.

Once again, a lot of users in the use of batteries in the very confused as to whether or not to wait until the compaq battery run out completely before charging. In fact, this question should be answered like this, if you can do is certainly a good thing, but the premise is your problem too. Of course, I am talking about here is not referring to the excessive discharge, excessive discharge Practice has proved that the battery is absolutely harmful, it will shorten the battery life. Therefore, when the notebook prompted a time of low power consumption will be able to charge the appropriate time. Some business has repeatedly stated that its lithium battery memory effect did not, this is very irresponsible. So when you have more battery power when it is better not to charge for the good, because the memory effect is real.

Thirdly, the need for long-term battery should be how to do, into the proposed 40-50% of the electricity, placed in the shade of the low-temperature, the following parameters will be able to note the problem.

      Of course, the best month we should come out with a EVO N410c battery , the battery can ensure a good state of preservation, and not let the loss of full electricity and cell damage.

Fourth, in notebook computers for use in “a month after the charge should be full-time release” if necessary. Notebook computer lithium-ion batteries used in general management with a chip and charge control chips. One-chip management in a series of registers, there is capacity, temperature, ID, state-of-charge, discharge, such as the number of values. These values are in use will gradually change. Personally, I think, in notebook computers for use in “a month after the full charge should take a” leading role of these amendments is to be improper, the value of the register, making the battery charge control and Evo N600C battery  with a nominal capacity of the line The actual situation. This is why the work could not be omitted, after all, the high-priced notebook or effemination the aristocracy.

The use of the last turn on, how to make the book more batteries for a long time. Since you bought a laptop is to use it, the battery is one of consumables, as is bound to use the time to renew and scrapped. What books to allow a longer battery life? Power-saving technology? Sleep? Hard to let hang? Reduce the brightness of the screen so? All these methods seem to be able to increase the so-called extension of the time. But you have never thought that such a meaningful extension of the time it? I do not run any open book process, do not open display, not to hard, I can not reach a longer period of time. This would be absurd, is used to use the notebook, rather than high-sounding setting. I therefore propose that we make good use of the notebook, rather than about how to use the notebook. Perhaps, two years after the notebook market is another world, your books have reached the ranks of the retired. As long as we pay attention to day-to-day use of Evo N610C battery  used to, the normal cells can be used, there is no need to be timid.

For notebook computers, batteries can be said to be a more important component, which has a direct bearing on the status of a notebook computer in an environment of the lack of power capacity.
The batteries in laptop computers and is an out-consumption components, the laptop battery involves the maintenance and rational use of the issue is frequently discussed topic.

As we ride in the Ni-MH battery models have been very difficult to see, so in this part of my presentation will focus on the widely application of lithium-ion battery.
General lithium-ion batteries for the life-cycle of 300-500 take charge of the meeting. However, this does not mean that you rarely use, it can be battery life extension.
As a battery of physical vulnerability to the original working environment in a variety of factors, which lead to cell loss is a major reason why the oxidation caused by the increase in battery internal resistance,
That’s why a lot of users complain that they will be full of battery in use why not all of a sudden the power. Therefore, this may wish to understand the problem,
That is when the end of the battery down the assembly line, its internal clock of life began to move about, even if you do not have to set aside the compaq battery,
Can only be delayed to a certain extent, the loss rate of no more than the battery. Then again, however, always put the battery side of the notebook computers that sense movement How can we talk about?

However, proper maintenance is not necessary, so many people have asked how to protect it in a battery life and not to retire so early.
As the battery life is determined by the number of charge, so avoid frequent use of batteries should be said to be one of the most fundamental way to
In other words, use the power of the environment as much as possible not to use battery power.

This again leads to a problem that is used in power when the Presario 1200 battery  is removed from the machine, which is one big headache of a problem.
To illustrate the problem, let us look at a table, this table gives the state-of-charge at different habits and ambient temperature to preserve battery capacity of the battery after a certain period of time.
