Sharp with 35.8% solar cell conversion efficiency refresh the record

“Efficiency is close to internal combustion engine. This is the conversion efficiency to achieve the ideal of breaking 50% of the solar cells in the process of a major breakthrough” (Sharp). Recently, Sharp, the conversion efficiency of solar cells increased to a record 35.8%. If the condenser to 1000 times the conversion efficiency is also expected to reach 45%.Sharp begun a new round of technical personnel development. Objective is to 1 / 10 the cost of non-condensing unit when the conversion efficiency exceeded 40% to PCGA-BP2NX Sony VGP-BPS2 sony VGP-BPS8 VGP-BPS9. To go beyond 40% as the goal is not to intensify the development of a Sharp. In order to achieve high efficiency solar cells, the technology development of competition are becoming more active.

Prior to this, the highest conversion efficiency is the U.S. NREL (National Renewable Energy Laboratory) in 2007, created by 33.8%. Condenser under the conditions of maximum efficiency is the United States Spectrolab have just learned in October 2009 of the 41.6% posted. Including Sharp, including the results of this and create a record of all compounds for the three-in-style multi-junction solar cells. Solar cell conversion efficiency to be increased to VGP-BPS9A/B Sony VGP-BPS3VGP-BPS9/S 319411-001 the limit it requires a mix of different band gap materials in order to take full advantage of the various wavelengths of light. Sharp focus on the past, manufacturing simplicity, chose the lattice constant close to the material. Namely, the top unit (the upper three-junction structure) of InGaP, the unit (ibid., middle) as InGaAs, at the end of unit (ibid., lower) for Ge, bottom of Ge.

This time, Sharp to optimize the band-gap for the first, at the end of unit Ge (bandgap of 0.67eV) from the InGaAs (ibid., 0.97eV) substitution, using InGaP (top), GaAs ( in), InGaAs (bottom), GaAs substrate combination. Therefore, in accordance with the order from top to bottom by PA3399U-1BRS Acer Aspire 3000 battery, from short to long wavelengths of light can be applied effectively to generate electricity.

To resolve issues through the reverse layering exist in such combinations InGaP lattice constant of GaAs substrate and other layers with quite different issues. This phenomenon may give rise to crystal defects, it is difficult to achieve high efficiency. To this end, Sharp turned the film over the past order to HP Pavilion dv2000 Battery HP Pavilion dv6000 Battery HSTNN-LB31 PA3399U-1BRS, through the use of from the InGaP (top) began in turn film “reverse cascade formation method” so that the lattice constant of GaAs substrate basically reached a consensus. Through the lattice constants of the different GaAs (middle) and InGaAs (bottom) inserted between the buffer layer, inhibiting defects. Taking into account the transmission wavelength, the buffer layer and top with the InGaP.

The use of reverse cascade formation method from the InGaP (top) began in turn to the superposition of InGaAs (bottom), the three-layer GaAs substrate need to separate, InGaAs (bottom) layer down to the Si substrate transfer on. InGaP layer in a direction to the surface over Inspiron 510m Battery Sony VGP-BPS9/B battery Sony VGP-BPS5. Bonding with the Si substrate to use is “similar to the solder material” (Sharp).

In addition to more efficient, the method can also reduce costs in the future. GaAs substrate separation process is currently used by curettage GaAs substrate method. If in the future to take advantage of plug stripped layer above EVO N410c Battery Compaq Evo N600 Battery, who wish to divest part of the implementation of ion implantation and other methods to complete the process, then, GaAs substrate is expected to achieve reuse. As the GaAs substrate is very expensive, so the realization of this method can significantly reduce costs.

With these improvements, “than crystalline Si-high two-digit,” is expected to reduce manufacturing costs to the current 1 / 10. Its use is currently limited to satellite via APple A1021 adapter or ibook g4 adapter, but with lower costs in the future may also be extended to other areas.

Conversion efficiency improvements do not stop there. 2025, Sharp plans to develop a module conversion efficiency of 40%, 1000 times the condenser when the conversion efficiency of 50% of the revolutionary solar cells. Through the InGaAs (bottom) below the addition of new layers, to achieve four resultant compound multi-junction solar cells through Compaq Evo N620C Battery Compaq EVO N400 Battery. Manufacturing methods of Acer BTP-58A1 battery is still the method of reverse cascade formation. In addition to the different band gap materials, the use of quantum dots band gap control layer is also expected to become a new layer.

South Korea’s LG and Taiwan’s AU Optronics (AUO) is scheduled to “Green Device 2009 Forum” (10/28 ~ 10/30) held on to explore the solar cell business and technology strategy seminar solar cells.

Use Their hearts to win the market

After getting name-brand products and product manufacturers rely on the support of the business, Yang Lin bigger and bigger, bigger and Shun. With the increase in business volume, he proposed the “people have me have, people have my excellent, their hearts, winning by quality” business approach to Aspire 3000 battery BTP-58A1 Acer LCBTP03003 . In accordance with this policy, they developed a standard service procedures, namely: on the request to replace a new battery of vehicles, not to engage in a change of the stuff, but first, repair the circuit, can not change the minimum change that can repair try to repair. Pairs of replacement parts, should be 11 pairs of users to make it clear what parts are bad, how much money the new accessory?

How much maintenance? Interview, talk about our demand for batteries in the matter, the Yang Lin with a smile said to us: “put ourselves in for the sake of the user to find ways to meet the user’s requirements, is fundamental to development of our products such as Sony PCGA-BP2NX Sony VGP-BPS2 N410 battery Compaq EVO N410c battery store . channels in the smooth circulation of commodities today, others do not have, people have my priorities, not only refers to the type and quality of goods, mainly refers to the quality of service, attitude and service level. ”

The interview, there have been client door, Yang Lin 11 to arrange an orderly manner. When an employee consulted the door of the vehicle circuit two problems, the topic turned to the technical aspects of this. “Automobile neural circuit like the person most likely to go wrong to VGP-BPS9A/B Sony VGP-BPS3VGP-BPS9/S. Sometimes everything be properly, that is, Dabu Zhao fire.” He Banzhao fingers for our calculations account: “a cart battery seven or eight hundred yuan, a car battery have four or five hundred yuan, 10% of the profits earn a lot of money, change the battery in my shop is not only save trouble, but also to make money, but we can not do that. do not make a sub-Mei Xin Qian, non – to allow customers to spend a money wasted is our shop aim! ”

Interview this point, we are not help against the Yang Lin awe. In the following interview with the staff, we also heard many touching stories, due to limited space, only confirmed the removal of two Zeyi Yanglin of person: one, a bad battery at Shazikou car users, called require on-site maintenance t oVGP-BPS2  VGP-BPS9/S Dell Inspiron 1721 Battery Sony VGP-BPL8. From Jiaozhou to Shazikou more than 60 kilometers, for a battery for a trip, round-trip costs are not even enough, but were driven Yang Lin not hesitate to strip in the past. An inspection, was originally the circuit had a problem. The driver was everywhere, said: “The battery, circuit failure, Shui Yebie looking for, we find Yang Lin, this person is.” Later, only the driver to the Young laemklad to more than 20 customers in there. Another thing are more twists and turns.

One day, a foreign driver to change the battery, Yang Lin is not by chance, a new inspection of the maintenance man did not follow the rules and the replacement of the battery circuit. Yang Lin came back immediately after the exchange heard down the battery has been tested and found that the battery itself is nothing, he immediately criticized the repair works are carried out and in accordance with the driver to leave the phone number to contact. Two months later, the driver passing Jiaozhou delivery at Inspiron XPS M1710 battery Dell Inspiron E1705 battery Dell Inspiron 1100 battery, but also came to the Yang Lin’s shop. Yang Lin will have a good rechargeable battery power back to him, and the money to come up with new battery back to him. Repeated Tuirang, this driver will have two batteries accept it, and then politely declined Yang Lin fed to a refund, he said: “Manager Yang, batteries, I’ve been using more than six months, and money will not retreat, and that your Wei Ren, I served! ”

Sixteen wind and rain, sixteen hard sixteen brilliant. Sixteen years ago, Yang Lin With a commitment to serve the user’s heart has won the trust of users. His shop, already from the “battery retail outlet” to “gel battery Great World City,” mode of operation is also changed from the family-run shop as powerbook G4 ac adapter powerbook g4 power adapter or EVO N400c Battery Compaq EVO N410c Battery Compaq Evo N600 Batteryhas 11 employees in the private sector, in the Jiaozhou dozens of battery distributors, his “Big World” accounted for a share of the market into more than four. End of the interview, Yang Lin ambitious told us: “Two months later, ‘Big World’ will be moved to a new business hall, the environment changed, but our customers sincerity, sincere, enthusiastic will not change, we will be do better! “

How to buy cell phone universal charger?

Mobile phone charger in the national unity before, each time to replace your phone charger is not a common problem still exists. Reporter learned from the market present, many consumers are choosing to use a “universal charger” and gadgets to solve this problem to Pavilion dv2000 Battery Pavilion dv6000 Battery HSTNN-LB31. Universal mobile phone charger currently on the market the brand, style and diverse, how to choose a suitable for your products? As the original charger and battery charging parameters of the design to match, so for the battery life and security, it should be the preferred original Charger or direct charge.

select universal charger, just for emergency needs. What kind of universal charger is good, first of all depends on the user’s individual needs. Is best to choose the time of purchase major brand products, bearing in mind the thick material is better. a specific choice, if you are using a single electric charge of a single mobile phone at Sony VGP-BPS3 VGP-BPS9/S battery 319411-001, with a need for inexpensive rechargeable Charger are also worried that the bad batteries, but do not care a bit less standby time, you can select a charging Current 200mA or so, cut-off voltage of 4V about universal charge, this specification can shorten the charging time, charging the completion of auto-stop, even when you occasionally forget to unplug the plug, but also worry about the battery charge would be bad .

On the contrary, if you aggressively pursue the battery standby time, at the expense of some battery life, or the use of inexpensive brand batteries, we must choose the proper overcharge the universal charger, as long as the voltage does not exceed 4.25V, generally do not cause swelling phenomena such as battery charging by APple A1021 adapter or apple a1036 adapter, the battery performance and life of that does not mean much, but still has some security implications to Evo N610C Battery. In fact both cases are relatively extreme, for most users, to find a balance between the two points, the most important.

If conditions permit, before using the universal charger a good idea to test with the multimeter. If there is no meter, you can simply verify that cell phones – in the universal charger remove the battery when the display is full, into mobile phones, mobile phone direct charge to continue to charge with 45Wh Apple PowerBook G4 Adapter and 65Wh Apple PowerBook G4 Adapter , if the mobile phone display at this time “to continue charging”, and remove the battery charge with the universal re-charge, 30 minutes later to try again, try to be repeated many times, if every phone show” continue to charge, “illustrates this universal charger charging the degree of saturation than original charger, but it also does not over-charging, the battery will not hurt.

Improve successful economic battery monitoring program

Improve successful economic battery monitoring program

Support the infrastructure of modern society must be based on a very high reliability of operation. Internet and telecommunications switching center server farms in order to ensure nearly 100% of the “trouble-free run-time” or system availability, they mostly rely on a very mature technology – lead-acid batteries, while the data storage center are used in high-tech. Typically, these key nodes, and many other important sectors are equipped with standby power, standby power supply is generally the first level inverter Sony PCGA-BP2NX Sony VGP-BPS2 sony VGP-BPS8, inverter pairs of VRLA (VRLA) battery or a similar performance, sealed gel batteries assembled battery Section of power conversion. The reason why the traditional techniques widely used, there are many reasons, especially lead-acid batteries affordable, but also with outstanding reliability. But while great but not perfect. VRLA battery life is limited (generally 12 years design life), often mission-critical systems using this battery as a backup power supply Apple iBook Blueberry Series Apple iBook FireWire Series, but changed regularly.

Failure may indeed occur to apple a1036 adapter. In a typical standby power systems, the role of the battery as its name – they always maintain a fully charged state of waiting for the main power failure. And the fully charged state of continuous small current through the “float” charge to maintain. If the float current is below a set limit, then the battery inside the gases produced by electrolysis will be re-chemical combination. In this case, a single battery float voltage is even slightly higher than the standard value of 2.27 V, may also damage the battery VGP-BPS9 VGP-BPS9A/B Sony VGP-BPS3. Slightly over-voltage will cause precipitation of the electrolyte capacity of more than Recombination more gas, these gases are not handled through the overflow valve. If the battery temperature is too high, even if the charging voltage is appropriate, can lead to electrolyte loss.

Other failure modes include early sulfation, very bad columns and grid connection, grid connection plate and the bad, electrolyte stratification and grid accelerate corrosion. There is yet another, though a small but catastrophic failure modes – thermal runaway, which is peculiar to VRLA gel batteries such as Toshiba Satellite P100 battery Toshiba Satellite P105 battery, and a failure modes, can lead to burst into flames. The only way to prevent thermal runaway is to monitor the internal temperature of the battery.

Just monitoring the battery voltage on the detection of lead-acid battery capacity decline in the role is very limited, it has been recognized throughout the industry. When the battery performance is declining, it is usually presented is that the nominal voltage, until the release of large currents can only apparent, but when its capacity has been severely reduced voltage drop prematurely. By measuring the proportion of electrolyte to determine the exact battery status, the method of the VRLA or sealed gel batteries does not apply; routine, the test battery VGP-BPS9/S 319411-001 Pavilion dv2000 Battery used in the only way is to discharge the battery pack to a controlled state of the following Pavilion dv6000 Battery HSTNN-LB31, but this approach need to stop using the battery. In addition, the depth of discharge also reduces the life of lead-acid battery; in on a regular basis to conduct its backup battery discharge test, as well as its main power supply with high reliability of the system, most programs use this test to determine battery life.

Recently, continuous monitoring can be of non-intervention electronic method can detect a single cell near the failure state, this method can not only save costs, while maintaining overall system availability. The predecessor of such systems is usually measured cell or battery pack or 45Wh Apple PowerBook G4 Adapter or 65Wh Apple PowerBook G4 Adapter (battery industry term which means that within the shell in the same package multiple battery) voltage – despite its limitations is well known – with charge / discharge current and ambient temperature. Some systems attempt to measure or guess the battery internal resistance, its effectiveness varies.

LEM’s Sentinel system is dependent on the basic parameters of a simple analog measurements of change leading product has now grown to the first three generation of the Sentinel III. It is custom-designed single-chip SoC (System on Chip) IC on the integration of analog and digital technology PA3399U-1BRS Acer Aspire 3000 battery BTP-58A1. The device configured in a measured terminal voltage, the battery internal temperature and internal resistance of the module, can provide accurate measurement results for the cost again in most of the backup system configuration can afford within the budget of the system, it is the design of a key elements.

The main performance indicators of rechargeable batteries

The main performance indicators of rechargeable batteries

Safety performance indicators for battery failure is unacceptable. In which the greatest impact is the explosion and leakage. The occurrence of explosions and leakage mainly related to the battery internal pressure, structure and process design (such as valve failure to Acer LCBTP03003 Latitude D600 Battery Latitude D610 Battery, there is no lithium-ion battery protection circuit, etc.) and should be prohibited by the incorrect operation (for example, a battery into a fire) of the. To AA 2300mAh Ni-MH rechargeable batteries, for example, indicates that the batteries 230mA (0.1C) charge 16 hours after 460mA (0.2C) discharge to 1.0V, the total discharge time of 5 hours, the release of electricity for the 2300mAh. Accordingly, if 230mA of current discharge, the discharge time is about 10 hours with 45Wh Apple PowerBook G4 Adapter.

 

Refers to a certain discharge conditions, the battery can release the total electricity consumption. In accordance with IEC standard and GB, nickel cadmium and nickel-metal hydride batteries in 20 ± 5 ° C conditions, in order to 0.1C to 0.2C charge 16 hours after discharge to the 1.0V power emitted when the Dell Latitude D620 Battery Dell Inspiron 710m Battery Dell Latitude D800 Battery’s rated capacity to C expression; Lithium-ion battery at room temperature, constant current (1C), constant-voltage (4.2V) after 3 hours under the condition of charge to 0.2C discharge to 2.75V emitted when the battery’s rated capacity of electricity. The unit of mAh battery capacity, and Ah (1Ah = 1000mAh).

Battery internal resistance refers to the current flowing through the Sony VGP-BPS12 battery when the subject of internal resistance. Charging the battery internal resistance is small between ibook g4 adapter and APple A1021 adapter, need to use special equipment can only be measured more accurate results. Generally known as the battery internal resistance is the charge-state resistance, meaning that the battery is fully charged when the resistance (corresponding to a discharge state of resistance, saying that after the battery fully discharge resistance by 65Wh Apple PowerBook G4 Adapter. Generally speaking, the discharge state of resistance Charge-state resistance than the large, and not very stable). The greater the battery internal resistance, the battery itself consumes energy more efficient use of the battery lower.

A great resistance when the battery charge is very severe fever to Sony PCGA-BP2NY battery PCGA-BP51 battery, so that the battery temperature is rising sharply. The impact on the battery and charger are all great. With the increase in the number of battery life, due to the consumption of electrolyte and battery internal chemical activity in the reduction of internal resistance of the battery will have different degrees of increase. The worse the quality of the battery up faster. Cycle life batteries that can be experienced repeated charge and discharge cycles to Dell Inspiron 510m Battery VGP-BPS9/B Sony VGP-BPS5. Battery life and capacity into the inverse relationship, the general Ni-MH battery cycle life of up to 500 times or more. High-capacity battery life is shorter, although up to 200 times or more. With the charge-discharge cycle life is also closely related to the conditions, generally the greater the charge current (faster charging), the shorter the cycle life.

Charge retention ability that is often talked about self-discharge, that means open-circuit state, the battery storage of electricity in certain environmental conditions to maintain the ability. Mainly by self-discharge battery materials, manufacturing processes, storage conditions, and many other factors with Sony VGP-BPS2  VGP-BPS9/S Dell Inspiron 1721 Battery. That the large current discharge capability. Digital cameras, power tools, electric toys, electric appliances in particular need to have excellent large current discharge performance of the battery. Large current discharge performance of primary and battery-related materials and production processes.

Usually the higher the temperature the greater the self-discharge rate. Rechargeable battery to a certain extent of self-discharge is normal to apple a1036 adapter or 45Wh Apple PowerBook G4 Adapter. With nickel-metal hydride batteries, for example, IEC standards require that the battery is fully charged after the temperature of 20 ± 5 ° C, humidity 65 ± 20% conditions, the open set aside 28 days, 0.2C discharge time of not less than 3 hours (ie, residual consumption is greater than 60%). Lithium-ion batteries and dry battery self-discharge is much smaller than Dell Latitude D620 Battery.

Activate the “aging” of the laptop battery

Feb 1

Activate the “aging” of the laptop battery

When the laptop screen shows the Sony VGP-BPS9 battery is damaged,what will you do? Therefore, the battery maintenance and rehabilitation needs of laptop users is the topic of concern. Maintenance process is also often referred to as “activation”, “activation”, a very vivid and to reflect that the battery “dead” and rebirth process.

 

I summed up the activation of a battery approach, its basic principle is that when the charge and discharge currents must be small (but not too small, or too long), there is to try to be filled, released completely. Cell damage because the battery in use after a period of time will “aging” of Asus A2 battery Asus A42-A2 battery Asus W5A battery. Concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled, the capacity also is naturally “down”. Since relatively large battery internal resistance, discharge voltage drop by high speed, the system can easily mistaken for a voltage not enough, lack of electricity (in fact, there is no electrical discharge).

Can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of lost working hours, the battery faster than when what it should be tempered, or else it will be finished sooner or later. In addition, many lithium battery failure is the battery package of a certain energy-saving result of core failure, a bad pot of soup mouse droppings. This phenomenon can not be avoided, because the battery power-saving core of each character can not be fully consistent with a long time there are some quality to Sony VGP-BPL8 Compaq Evo N600C Battery Compaq Evo N610C Battery, the aging first weakened, undermining the whole (series after) the discharge curve. It simply means that section of bad batteries before charging full discharge also finished first place, but this time the capacity of the other batteries have not been fully utilized.

The core of a power-saving overcharge / over-discharge will not cause the battery monitoring circuit that the whole is full of / discharge end of the. For example, when charging other batteries start getting close to full charge when pressed, that section of bad batteries may have reached the terminal voltage of 4.30V or higher, resulting in overcharge damage, while others are sufficient dissatisfaction. Editor’s note: For internal batteries battery damage, the “Chinese computer education” 2001 No. 2 has a very good article – “notebook computer batteries DIY” worth learning from. Interest, courage and capacity of friends can try to open the battery pack, believe that the help of multimeter to Compaq EVO N400c Battery Compaq EVO N410c Battery Compaq Evo N600 Battery, you can quickly find the damaged batteries (voltage abnormality). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product. The battery charge and discharge lithium-ion battery charging poses as a way of fast charge constant current in the voltage reaches a certain value and then to slow charging constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices.

System load when a large charge current on small, whereas the large, the current from the AC power adapter power margin decision. Clearly, the system will charge the battery and other components, such as CPU, hard drive, LCD and other competing energy sources to Dell Inspiron E1505 Battery. I tried to run side SuperÏ€, while charging the way and found that the charge current in the 0.70 ~ 1.70A between the changes, can not meet the lithium-ion battery charging requirements, so I fear that this will work, rechargeable batteries were defective to Compaq Evo N620C Battery Compaq EVO N400 Battery. IBM statement calling for notebook computers will not operate when the charge is probably the reason. Charge at boot time, if we can select the charge mode, you do not choose fast charge mode (Express charge mode), to avoid premature battery “full.”

There is a time of low battery power to prohibit the use of the highest CPU performance in order to reduce the power of the competition. If the notebook computer’s CPU is to support the use of SpeedStep technology, it is best to install the driver (the vendor will be responsible installed) to facilitate the adjustment performance to Compaq EVO N410 Battery Pavilion ZD8000 Battery. SpeedStep program icon is a blue flags, right-click performance tuning options it can occur to powerbook g4 adapter . Under the Windows XP system, SpeedStep program will be problems, this time to rely on or to modify the BIOS parameters of the regulation of a number of brand-specific programs, such as IBM notebook computer software is very powerful tool.

Electrical discharge of lithium, or always-on, let the natural discharge better. Is best not to use physical methods (string of resistors in the class). Not to say that that was not feasible, but relatively large risk, if the internal protection circuit was not working, then set aside the batteries as Dell Latitude D800 Battery Dell Inspiron 510m Battery VGP-BPS9/B battery VGP-BPS9A/B battery, and the worst is probably the battery explosion, of course, this unlikely. Circuit hidden dangerous is not impossible, a number of big-name manufacturers have found that the design of potential risk factors exist in a battery recall, as mobile phone battery when you do not hear the explosion.

Little knowledge:
Generally speaking, laptop battery protection circuit in the part is usually voltage block, control chip, insurance, and temperature probes by Compaq EVO N610V battery Compaq EVO N620C battery. Temperature protection device is usually a one-off, the inside has a fuse (some 130 ℃ Fuse), is used to monitor the voltage regulator block work with powerbook G4 ac adapter. If the charge-discharge process exceptions, immediately there will be a current through the temperature protection device, will fuse fuse, the battery’s internal circuitry at this time for the open circuit state, and can not be restored.

If you want to repair only the replacement of temperature protection device, but such temperature protection device on the market hard to find. Discharge is the discharge current as small as possible, the operation is to slow down and let the CPU, hard disk stops turn Inspiron 1721 Battery Sony VGP-BPL8 Compaq Evo N600C Battery, transferred the darkest the screen (or close the switch off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent premature detection of laptop battery shortage. I have disabled the hard disk, close the screen, cancel the power of the state police under the laptop completely discharge (put a close to 6 hours), the battery capacity from 31.72Wh restored to 33.65Wh or 65Wh Apple PowerBook G4 Adapter.

Use common sense in winter Notebook

Winter, most areas have become very low temperatures in some areas, temperatures can reach below zero, this cold environment, using a laptop compute SONY VGP-BPS9/B VGP-BPS5r, said there are many, if not careful, you will find that laptops are sometimes fragile. The following, I’ll talk to you about some of the winter using a laptop computer Note:

  • To reduce outdoor use

Most notebook computers are designed for civilian use and do not have a higher resistance to low temperature properties, and its LCD screen is usually designed to work in the 50 ℃ ~ 0 ℃. If the outdoor temperature exceeds the design work, will result in: 1 to shorten the life of LCD screens; 2, LCD screen, coagulation, notebook computers Pavilion dv2000 Battery Pavilion dv6000 Battery stop working. Most notebook computers use lithium-ion battery, this battery at 20 ℃ with a minus charge will be reduced to normal with 80% of electricity, which will result in: 1, shortening battery life; 2, lower notebook battery life.

  • To prevent condensation

Like glasses lenses, in the cold outdoors into a warm room, a sudden, the lens there will be a layer of water vapor, these drops of water and gas will be produced into a condensate. If you use your laptop outside in the cold, suddenly entered the room a warm spring, notebook HSTNN-LB31 PA3399U-1BRS Aspire 3000 batteryscreen will not only produce condensation, which also have a lot of condensation of water inside. Appearance of condensed water can wipe immediately with rags, but could not wipe the internal condensation of water, and electricity is likely to cause short-circuit the motherboard.

  • To prevent static electricity

Static electronic products is an absolute killers, weak weak electrostatic breakdown in due course, can also be electronic components, the so-called invisible is that you do not notice its existence, and it really does indeed threaten the security of laptop computers . Relatively dry in winter outdoors ACER BTP-58A1 LCBTP03003 DELL Latitude D600 Battery Latitude D610 Battery, but the cold weather, we have put together a number of man-made synthetic or wool clothing texture, it is easy to make the body produce a large number of static electricity, careless encounter laptop Yi conductive elements, such as: USB interfaces, laptop computers, there may be damaged by static electricity.

  • To maintain a smooth heat

In winter, we wore thick cotton-padded clothes, with a notebook computer notebook computer is very easy to plug a few cooling mouth, such as: laptop cooling port side and quilt cover. Cotton-padded clothes is not only easy to plug the cooling mouth, and even many of my friends like the winter in bed using a laptop Latitude D620 Battery Dell710m Batterycomputer to a laptop so the heat is more easily blocked port. Notebook computer that there is no heat flow, the internal temperature rises quickly, ranging from notebook computers at work performance or alarm, while in damage to electronic components inside a notebook.

  • Do not rely on power supply

A lot of friends in order to extend laptop battery life, often the power can be used in a case of unplug laptop batteries, in the winter you do so easily lead to data loss. In winter the use of electrical appliances are more energy-intensive and very vulnerable to temporary power outages, if the notebook computer does not insert the Latitude D800 Battery Inspiron 510m Battery, when power failure occurs, notebook computers will immediately crash, are working without any doubt the data is lost. Therefore, the security of data to work in the winter when you try not to unplug the laptop battery.

These are my use of laptop Apple A1189 Apple A1185 in the winter summary of some of the common attention, hoping to draw attention to, and hope we can learn by analogy, a lot attention to other laptops did not mention the use of the winter note, let’s notebook computers in winter same loyalty for our services.

Panasonic Are not afraid of short-circuit fire —- releases new laptop battery

Diannaozhijia (PChome) 12 Yue 23 AP, today I learned that Matsushita (Panasonic) today announced a new laptop battery technology, the product is not only the current conventional batteries have a higher battery capacity and can effectively avoid the short circuit fault caused by the Sony PCGA-BP2NX Sony VGP-BPS2 sony VGP-BPS8 battery caught fire.

Now laptop batteries because of defects in a fire caused by accidents have frequently occurred from time to time there will be notebook manufacturers announced the recall of its batteries, this phenomenon can not help but make a lot of users “tremble with fear.” Regrettably, however, though often caused by an accident, but the long-standing tradition of battery VGP-BPS9 SONY VGP-BPS9A/B technology has been no progress.

The Panasonic announced a new battery, though not a revolutionary update, but let us see the battery industry has not stalled. The new laptop battery 3.1Ah capacity of one bomb will be used on batteries to replace the existing 2.9Ah batteries, thus giving longer VGP-BPS3 319411-001 battery endurance. Another song is still the battery positive and negative in the installation of the insulation between the metal oxides can effectively prevent the battery short-circuit caused the fire phenomenon.

Panasonic just released a new current battery designs, seems to come out finished products also need a longer time and I hope the new Panasonic laptop battery for players to bring a psychological boost. Pairs of players interested in this Apple A1080 Apple M8416 Apple M7385 battery please pay attention to the follow-up reports PChome.
