popular battery

Some friends in the laptop battery to charge, charge that the longer the use of the longer, in fact, this is not right. We look at the most commonly used in the original lithium-ion battery, is generally used (GB/T18287 2000 norms), first of all constant current charge, that is, a certain current, and battery charging voltage as the process of gradually increased, when the battery terminal voltage to achieve 4.2V (or 4.1V), to constant current charge for charge voltage, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process to continue to gradually reduce, when reduced to 0.01C, charging that Termination. (C batteries based on current nominal capacity of a control method that, if the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not Ah, 0.01C is 10mA.)

Why is that the charge for the end of the 0.01C: This is GB/T18287-2000 national standards laid down as well as the discussions. Previously it was generally for an end to 20mA, the Ministry of Posts and Telecommunications YD/T998-1999 industry standards provided for in the same way, that is, no matter how much battery capacity, to stop all current 20mA. GB 0.01C provided help to more full charge, through the identification of a party manufacturers benefit. In addition, the national standard provides for the charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours, and that the end of the charge.
So, no problem with the quality of the batteries should be 8 hours to reach 0.01C, the poor quality of the compaq battery, and then filling it is also meaningless. Lithium-ion or lithium polymer rechargeable batteries in the best rate of 1C, which means a 1000 mAh battery of 1000mA to the current fast charge to charge such a rate can be achieved in the shortest time charge, but will not reduce the Battery performance and shorten the useful life. For the ever-increasing capacity of the battery pack, want to achieve such a satisfaction rate of charge to increase the charge current value is inevitable.

Lithium-ion battery nominal voltage 3.7V (or 3.6V), charging cut-off voltage 4.2V (or 4.1V, the batteries under the brands have different designs). What is the difference between battery 4.1V or 4.2V: consumers do not have the distinction, depending on batteries manufacturer of the product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is the basic 4.2V. The rechargeable batteries of 4.1V to 4.2V happen: will increase the capacity of the battery, with a good feeling, and standby time, but will reduce battery life. For example, the original 500, reduced to 300. By the same token, to the 4.2V batteries have been sufficient, it will lower its short-lived. Lithium-ion batteries is very delicate. Since the Presario 1200 battery  within a protective plate, we can rest assured that it had: No, because the board to protect the cut-off parameter is 4.35V (this is good, the bad to 4.4 to 4.5V), protection of the board is to meet in the event, if per Times have been sufficient, the battery will decay quickly.

Therefore, the charge is generally eight hours a disproportionate amount of time is not useful at all.

First, when the storage power loss. Xinhua refers deficit state did not use the laptop battery charge in a timely manner. Loss of idle state power longer, more serious damage to the battery.

Second, the test on a regular basis. In the process, if electric cars continued the trip mileage in a short period of time all of a sudden drop in more than 10 kilometers, then the battery is likely to at least a piece of broken cell battery appears, softened plate, the plate active substances, such as falling short-circuit phenomenon . At this point, the batteries should be repaired in time to professional bodies to inspect, repair and distribution group.

Third, to avoid high-current discharge. Electric cars at the starting line, manned, uphill, please use pedal power to help avoid a momentary high-current discharge. High-current discharge easily lead to the creation of lead sulfate crystallization, to the detriment of the physical properties of the battery plate.

Fourth, the right to master the charging time.
In the process, according to the charging time to grasp the actual situation, in general batteries are recharged at night, with an average time of 8 hours. If the shallow discharge, the battery will soon be filled, the charge will continue to have sufficient, and that leads to cell loss, fever, to reduce battery life. Therefore, the compaq battery discharge to a depth of 60% -70%, a charge the best power.

Five to prevent exposure. Electric cars is prohibited under the sun exposure. High temperature environment will increase the pressure on the internal battery by batteries pressure limiting valve automatically opens, is a direct consequence of the increase in the loss of water, batteries, Armada M700 battery  and excessive water loss will inevitably trigger cell activity decreased to accelerate the plate to soften, charging shell Body heat, from drums, such as deformation of fatal injury.

Six to avoid charge when Heat pull the plug. Charger output plug loose contact surface oxidation, and other phenomena will lead to Plug Charging hot, the heat too long may lead to short-circuit charging plug directly damage the charger and bring unnecessary loss. So when they found out that the situation should be cleared in a timely manner or replacement connector oxide.

Linear Technology of the United States for electric vehicles, hybrid market, such as lithium-ion rechargeable laptop battery control unit used to monitor voltage IC “LTC6802″, in the series after the unit increased voltage, quarantine non-use device can also be detected in each The voltage unit.

IC up to watch a 12-unit (maximum voltage of 60V), even if the cells in series to become more than 1000V voltage of the battery pack, as long as it is every 12 months to set up a unit IC, you can monitor the voltage on each module. As a result of the use of non-IC between the high-voltage transmission signals, so do not have the package and optocoupler isolator can use.

In addition, users can set any voltage of each unit to monitor the over-voltage and low voltage state. Against over-voltage, there is a built-in can use the built-in MOSFET switch unit will discharge an average of the circuit. In order to filter IC voltage unit, there are built-in ΔΣ AD-converter can be detected within 13ms in each unit’s voltage.

Linear Technology said that corporate Japan, and hybrid electric vehicles, such as car in the field of rechargeable Compaq battery voltage monitor IC “strive to be in Japan into a 7 share.” In addition to the car in the field, but also ready to be used in electric scooters, electric wheelchairs, forklift trucks, medical equipment, uninterruptible power supply (UPS) systems, high-voltage equipment. In addition to the company’s supply IC samples, but also to prepare a presentation board.

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 its best.
3. Although the Ni-MH laptop 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” an important point.
4. Rechargeable battery, charger should pay attention to the surrounding heat and not to put too many chargers around the debris. The battery contacts to avoid oxidation. If the application of oxidation of paper or cloth wipe, do not sandpaper or grinding wheel, or else they will lead to more serious oxidation.
5. Not for a long time, remember that the battery cell from the warehouse out, under dry conditions, the recommendation into the battery box, to avoid short-circuit the battery contacts and oxidation.
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 nickel-metal hydride batteries have 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 M2000 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. 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 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. Charge for a long time to the 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but will charge the full charge is enough, and do 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, such as the period of hot-selling LCD Panasonic BQ-830 smart charger rapid charger in this regard was especially outstanding.
10. Slow injury does not charge the M8511 battery  charge time is too long, however; fast charge time can be saved, but the batteries have hurt, even if the surface is the best the world can only be good charger Need to reduce the extent of damage, 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 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 finished after the charge voltage and power good voltage on it.
12. To talk about the final charge and discharge.
   The high-grade NI-MH battery charger using a-DELTA V battery voltage detection 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 M6091  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 think much, on the contrary, now that the use of small electrical appliances, and more high-current charge. The first is a matter of time, do not have to speak. Then, Ni-MH battery has a characteristic that you charge the greater the current, it can release the greater the current, electrical 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. 0.5C can be used to conduct charge. Discharge, under normal circumstances, after the black electrical charge can be taken up, NI-MH little memory effect. But after a period of time, as well as to balance the use of batteries, battery-activated, 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 A1012  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, the battery internal resistance will increase. After the battery charge a higher temperature, cooling, and so on before use.
  
   Battery for a long time do not have to re-use, the best sufficient to reactivate the 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. Do not tempering the impact of the battery, do not burn.

At present, non-polluting electric cars because of their advantages such as light and favored by consumers, and the mileage is a consumer to measure the length of electric cars good or bad one of the main criteria. It is well known that battery electric cars will be played a decisive role, then the laptop battery electric vehicle maintenance which should be noted that the problem? The following advice for reference only.

First, when the storage power loss
Xinhua refers deficit state did not use the battery charge in a timely manner. Electricity deficit in the state under sulfate, lead sulfate crystals attached to a board, plug the electric ion channels, resulting in charge did not fall. Loss of idle state power longer, more serious damage to the battery.

Second, regular testing
In the process, if electric cars continued the trip mileage in a short period of time all of a sudden drop in more than 10 kilometers, then the battery is likely to at least a piece of broken cell battery appears, softened plate, the plate active substances, such as falling short-circuit phenomenon . At this point, in time to repair the battery professional bodies to inspect, repair and distribution group. This can extend the battery life relative to maximize savings.

Third, to avoid high-current discharge
Electric cars at the starting line, manned, uphill, please use the pedal assistance and to help avoid a momentary high-current discharge. High-current discharge easily lead to the creation of lead-acid crystallization, to the detriment of the physical properties of the asus battery plate.

Fourth, to master the correct charge time
In the process, according to the charging time to grasp the actual situation, in general batteries are recharged at night, with an average time of 8 hours. If the shallow discharge, the battery will soon be filled, the charge will continue to have sufficient, and that leads to cell loss, fever, to reduce battery life. Therefore, the battery discharge to a depth of 60% -70%, an electric charge the best, according to their actual conditions necessary charge to avoid the charge of injury.

Five to prevent exposure
Electric cars is prohibited under the sun exposure. High temperature environment will increase the pressure on the internal battery cell which was forced to limit pressure valve to open automatically, is a direct consequence of the increase in the loss of water, batteries, M2000 battery  and excessive water loss will inevitably trigger cell activity decreased to accelerate the plate to soften, charging shell Body heat, from drums, such as deformation of fatal injury.

Six to avoid charge when Heat pull plug
Charger output plug loose contact surface oxidation, and other phenomena will lead to Plug Charging hot, the heat too long may lead to short-circuit charging plug directly damage the charger and bring unnecessary loss. So when they found out that the situation should be cleared in a timely manner or replacement connector oxide.

In the context of high oil prices, solar technology industry is being limelight. Recently, China and Japan have stepped up their study of dye-sensitized cells. The laptop battery  cost is only one-tenth of the current silicon cells. But there are also photovoltaic experts believe that this type of battery is still a lack of stability, and its commercial operation has to be seen.

With the surge in demand for products, as the main raw material of silicon photovoltaic material prices in recent years, soaring. In 2005, the spot price of polysilicon only 55 U.S. dollars / kg, but on the rise in 2006 to 200 U.S. dollars / kg. Downstream capacity expansion by the shortage of material impact to December 2007, the Mogao polysilicon market spot price to 400 U.S. dollars / kg, the market price has remained at 300 U.S. dollars / kg.

Silicon is expected not only to the high cost of the photovoltaic component manufacturers Xiaobo profits, but also slowed the pace of development of photovoltaic industry. In this context, a new type of academic research and development of photovoltaic cells have begun in full swing.

East China Normal University is satisfied with the integration of advanced optical equipment Engineering Research Center of the Ministry of Education based on the principle of chloroplast for photosynthesis, has developed a new type of chloroplast structure similar to the battery – Dye-sensitized solar cells, solar energy can be Into electrical energy.

According to the Center for Research Assistant Mr. Pan, dye-sensitized cell and the introduction of silicon photovoltaic cells into a completely different principle, can greatly decrease the cost of raw materials, silicon is only one-tenth of the Toshiba battery  . At present, this new type of solar photovoltaic conversion efficiency of more than 10%, close to 11% of the world
The highest level.

“However, the product is still at the laboratory stage, have not yet entered the large-scale business promotion.” Mr. Pan said.

It is worth noting that Sony has recently announced that it has successfully developed a non-use of a new type of low-cost silicon solar cells, the production cost on the market today only one-fifth of the battery into Silicon very One. The new solar cells use the same principle is the dye-sensitized. The new product uses photosensitive dye-based, without the use of expensive large-scale production equipment, which will significantly reduce production costs. Sony said the new products will be the current silicon solar cells risk is very low.

As the third generation of solar cells, dye-sensitized cells have other advantages, such as lighting conditions do not ask for much, even if the sun is not enough room, its photoelectric conversion rate will not be affected significantly. In addition, there are many interesting uses of its. For example, substitute plastic glass “splint” can be made of soft flexible battery; it will make the display can be side of the power generation, light-emitting side, to achieve energy self-sufficiency.

Nevertheless, some experts are not optimistic. The authority of the domestic photovoltaic experts, Shanghai Solar Energy Society chairman Professor Cui Rongqiang, said: “This new product is also the most fundamental issue is stability. As we all know, in the sunlight, the dye will not even change the color, not to mention the band A. And once the band structure changes, the performance will change. In fact, the current world, not a dye-sensitized cells in the sustained and stable operation. “.

In his view, the product of the commercial operation early also made it. Prior to that, first of all should be based on standardized test to determine solar energy conversion efficiency of its Such efficiency should also be tested through a third party in order to obtain credible results.

“Silicon is expected sooner or later the prices will come down, come down 10 times in the future, if so, whether the dye-sensitized cells have on the value of hard to say. After all, silicon cell technology is not expected to suddenly come out, but widely recognized throughout the world , A more mature photovoltaic technology. “Choi Yong-keung said.

In response, East China Normal University is satisfied with the integration of advanced optical equipment project of the Ministry of Education Research Center, a research assistant, said Mr. Pan, dye-sensitized cell after one year may be the fastest to enter commercial production.

How to use high-performance notebook batteries

Although many notebook computer manufacturers have claimed that their notebook computer battery life can be as long as the number of how many hours. A notebook computer to use in laptop battery-powered, the assumption that the battery has been full of electricity, to use the actual 3 hours have been pretty good. Therefore, proper use of laptop computers, notebooks will extend the use of the time.

1, as far as possible not to use an external device

For a number of external devices (such as C equipment cards, USB devices, etc.), the use of batteries when they should be pulled out as far as possible in order to save electricity. Because some of the large power equipment, such as: USB interface card interface of the PC or external hard disk box, the external drive’s power consumption in devices such as 5V 500mA or so, will considerably shorten the battery life.

2, not banned the use of the equipment and interfaces

In general, notebook in which some of the equipment and then often do not use the interface, if you use the notebook when using ibm battery-powered, so they can temporarily disable the equipment and interfaces. You can disable them in BIOS, if you are using Windows 2000/XP operating system, can also “Device Manager” double-entry devices to be banned.

3, closure of the screen saver

Many people think that screen saver may not power, in fact, a number of large and complex screen saver may be higher than your normal run-time power consumption even more, so do not open the screen recommends that protection.

4, choose the right way off

Would like to close the laptop, will appear on “standby” and “sleep” and “off” option 3, respectively, the choice of how to use it? This is based on the need for recovery time and power consumption requirements. As the laptop’s battery time is limited, so the best control power consumption as much as possible. As a result, do not have the time, we must try to avoid power consumption. Then again, if completely shut down, and then start from scratch Windows, the amount of time spent on too long. Moreover, the resumption of the hard drive when the traffic increase will be a corresponding increase in power consumption. Therefore, we must take full account of power and restore the balance of time, select the appropriate method of shutdown.

5. Disable the alarm function of power

Right-click on the desktop, in the pop-up menu and select “Properties”, then select “screen saver → → power alert,” disabled “insufficient battery alarm” and “a serious shortage of battery alarm” function. When the ThinkPad T60 battery  show 0%, still be able to use force for a period of time, this time you should immediately save the document. Because the electricity completely exhausted, the laptop will not give any tips on the forced shutdown.

6. Use Intel SpeedStep automatically down -

If the laptop SpeedStep technology used to support the CPU, the processor so that it can be in the mode of 2 free to switch between, that is, when the maximum power performance and battery mode when the ThinkPad T20 battery  optimized mode.

The new battery or the depth of discharge of the laptop battery, the first to use the slow-charging, the number of recycling before they are allowed to reach its maximum capacity, and can be recharged using the fast charge mode. Nickel-cadmium battery is not completely run out of electricity in the conduct of charge, it would have the effect of memory, no matter how long always charge less than the rated voltage and capacity, thus shortening the life span of batteries used.

The new battery or the depth of discharge of the battery, the first to use the slow-charging, the number of recycling before they are allowed to reach its maximum capacity, and can be recharged using the fast charge mode.

Nickel-cadmium ibm battery is not completely run out of electricity in the conduct of charge, it would have the effect of memory, no matter how long always charge less than the rated voltage and capacity, thus shortening the life span of batteries used. To reduce the use of batteries each time. Therefore the use of nickel-cadmium batteries should be based on “sufficient light” principle, used by the Chargers should have discharge functions at the same time in the discharge end of the minimum when the electricity automatically into the state-of-charge, charge up to the full.

Fast charging up to the rated capacity of up to 85% of capacity, as a means of emergency, the lowest possible number of proposals in this way. Generally slow to adopt common or sufficient manner, so that each may be able to charge full, in order to ensure the battery Life.

When the batteries need to be stored for a period of time, the batteries should be filled to prevent the ThinkPad T42 battery  from the idle release, storage battery appears too long put off, the effect of the use of batteries affected.

Has been on the memory effect of nickel-cadmium batteries can be slow release (complete shine); slow charge cycle repeated three times as much as possible the way for the restoration of full capacity.

Despite the nickel-metal hydride batteries for non-memory effect, but often slow to adopt sufficient and full of shine, so as to ensure rational use of the battery.

Of lithium-ion battery charger must be dedicated.

Generally slow in charge when the battery charge time in more than 10 hours, when the battery charge time is already short ThinkPad T60 battery  charger on the show have been filled, and the use of a very short time to appear on the cell phone battery less than a clear instruction as to nearly end-of-life battery.

Rechargeable batteries for mobile phones, large-capacity long standby time, users will no longer convenient to use mobile phones, but the battery does not mean that the quality will certainly be a good, good or bad depends on the measurement of battery voltage plus when the load voltage stability , And the ThinkPad T20 battery  used in life.

If the user wants to extend the effective use of laptop battery time, in addition to a guarantee that the quality of the charger, charging the right skills is also essential, because the poor quality of the charger or charging the wrong way will affect the use of time and battery life cycle The following is the author sorted out the charge related skills:
     1. Battery factory, manufacturers have carried out active treatment, and pre-charging, the battery has more than electricity, a friend said battery charge in accordance with the adjustment period of time, the standby is still a serious shortage, assuming it is authentic battery cell, under such circumstances Should extend the period of adjustment to conduct three to five full charge and discharge.
     2. If the new phone to buy a lithium-ion battery, then the first three to five times charge commonly referred to as the adjustment period, more than 14 hours should be sufficient to ensure the full activation of lithium-ion activity. Lithium-ion batteries no memory effect, but has a strong Sui, should be fully activated, can we guarantee that the future can use the best performance.
     3. Some automated intelligent rapid charger when the lights changed direction, said only 90 percent full. Charger will automatically change to slow recharging the sony battery is full. After the best use of the battery is full, otherwise it will shorten the time.
     4. Before charging, lithium batteries do not need special discharge, improper discharge it will damage the battery. Charging as much as possible to slow Chong Chongdian to reduce filling fast; time not more than 24 hours. After three to five times the battery fully charge and discharge cycles of its internal chemical substances will be all “activate” the best use of effects.
     5. Please use the original or a better brand reputation of the charger, lithium batteries for use lithium PCGA-BP2S charger, and follow instructions, otherwise it will damage the battery, or even dangerous.
     6. Many users are often in charge of the cell phone when driving, in fact, this will very easily harm the life of the phone, because in the process of charging, cell phone circuit boards will be fever, at this time if there is external phones, may be instantaneous Current return, the internal components for mobile phones damage.
     7. The life of the battery charge and discharge decisions on the number of repeated, it should be avoided as far as possible, when more than rechargeable battery, this will shorten the life of the battery. Phone shutdown time for more than seven days, the first mobile phone batteries should be fully discharged and fully charged after use.
     8. There are phone battery self-discharge, nickel-hydrogen battery when not in a day of surplus capacity will be about 1% of discharge, lithium batteries per day will be 0.2 percent to 0.3 percent discharge. In the battery charger, to make full use of special socket, not the charger and sharing of household electrical appliances such as TV outlet.
     9. Although the mobile phone network coverage in the region, but the phone off charge, and the phone has been unable to accept the call. At this point, you can use the phone’s Not transfer of functions, the phone will be shifted to the side of the fixed telephone, the calls to prevent the loss, this method is not for the mobile phone network coverage within the region or weak signals were temporarily unable to get through when applicable.
     10. Do not expose the PCGA-BP2T  under high temperature or cold, like the San Fu days, should not be placed on the car phone, and withstand the scorching sun exposure, or get air-conditioned rooms, blowing straight in the air-conditioned places. When charging, the battery a little heat is normal, but we can not let it Jinshou high temperature of the “torment.” To avoid such a situation occurred, it is best at room temperature for charging, and not to cover anything on your mobile phone.
     11. Nickel-cadmium (N iCd) before the batteries must ensure that the battery is no electricity, and must ensure that rechargeable batteries fully charged.
     12. If the battery of the phone too long without using, preferably to the phone for the maintenance department to deal with battery for a living, but also able to use a DC constant pressure, voltage adjustment for the 5 ~ 6 V, current 500 ~ 600 mA reverse connect battery . Note that Yi Chuji liberalized, most can be repeated three times, after such treatment, reuse original Charger “period of adjustment” charge.
     13. The longer the time when the charge is not good, not to protect the circuit after a PCGA-BP2V  charge should be stopped, otherwise batteries overheating due to heat or impact on performance.
     14. Lithium-ion battery charger to be selected for, otherwise it will amount to less than saturation point, affect the performance of play. After the charge, should be avoided at the Chargers on more than 12 hours over a long time not to be isolated to buy mobile phone batteries and cell phones must come see! .

Battery maintenance knowledge – no external power, unplug the battery

We often get such a proposal, in the external power adapter, the laptop battery should be removed, that the use of power, the battery will be conducted on the top charge, not only increase the number of charge cycles, but will also cause a charge of, which in turn Damage to battery life.

The actual situation is that the pool is removed, the conflict focused on the use of an external battery power when the issue of whether the charge. We should know that the number of battery charging and discharging directly related to life, the general set of lithium battery charging and discharging a fixed number, number of charge cycles, only 400-600, after special improved products but also 800 times, on each charge a battery Retired to a step forward. The first view is nothing but fear the use of power, the battery will be conducted on the top charge, not only increase the number of charge cycles, but will also cause the charge.

     But the current brand models, the fully charged battery-boost, the use of an external power source will not recharge. In fact, many notebook makers are now taking into account the vulnerability of batteries and products into the sony battery-protection technology, thus different from the corresponding brand laptop battery charge protection technology on different, like some large manufacturers in this area very Yes, such as: IBM, HP, Compaq, and so on. Which is considered the most thoughtful of IBM, IBM laptop battery discharge to detect the situation, ThinkPad notebook battery power only less than 95 percent of the time will be automatically charged. This battery can play a very good protection, now many other manufacturers have also followed. Therefore, such as batteries, you do not need to use when drawing down, because only when less than 95 percent of electricity when it will charge.

     But even so, if you are a long time to use the computer or the battery removed to a better, because notebooks have long run the heat will cause some harm to the battery. But some other “small brands” laptop batteries, may not enjoy such treatment, because it did not take the battery inside the protection technology. I like to use a certain brand of notebook computers, if fully charged battery on the top, use an external power supply, certainly, the first charge, because the PCGA-BP2Sy  storage, there will be losses, it is impossible to achieve 100 percent, if not 100% , Connected on the power charge. Each access to external power equivalent to a battery charge, although only a small charge will be time. Therefore, we propose the use of the machines under their own circumstances, check notebook brochures, choose to use an external power supply when the battery is removed. Brand models by adding a battery of battery-protection technology, generally do not have to worry about an external power supply would result in a charge the batteries, small brands may not be such a treatment, so that everyone in the use of the machines under their own case may be , Check out the notebook brochures, choose to use an external power supply when the battery is removed.

   Battery maintenance knowledge – attention to other matters

    To minimize the number of PCGA-BP2T 
     The number of battery charging and discharging directly related to life, filling each one, battery on a step forward to retirement. If regular repeatedly inserted in the day supply, and equipped with laptop batteries, the greater the damage the battery. Because each access to an external power supply equivalent to a battery charger, a battery naturally Zheshou. Although the above theory of the case, but each time to remove the battery is very convenient, with no battery cases, if the brown-out would lead to a sudden loss of data. Therefore, we do not recommend that users must remove the battery using a laptop. However, if the customer would like to save batteries, the vast majority of the time or the use of power, but also to avoid the risk of power, you can choose to use an external power supply when the battery removed.
