MP3 player makers early in order to reduce costs, once the use of 7 batteries as a power system, and players get smaller and smaller, 7 cells had been eliminated, and lithium batteries become a standard. The advantages of lithium batteries is obvious, but life is limited, once the increased use of MP3 players, 40Y6797 batteries, using real time is short in late May that persist in less of 30 minutes, MP3 player, Hey do is the result of fragmentation?

The battery is broken, how do

If the warranty period, this problem occurs, we suggest that you’d better go after-sales service, in most cases you can receive a free replacement service if the private sector inside replace the battery, then the only years warranty has expired, is not worth the candle.

If past the repair date, you can search through the network the first look at MP3 players in your hands models lithium VGP-BPS2C battery used in what is, in particular the tension to be constant. Hot Models in general the mainstream, such as Meizu, Apple, Samsung, trademarks Onda, online can not directly buy an alternative to lithium battery standard, as the instructions to respond to the gift of the battery of specialized tools, the machine can be themselves outside Quhuan hands.

However, a significant portion of the MP3 player, use lithium batteries are non-target, then how should we do? In fact, we can go to the local mall to buy electronics for lithium batteries same voltage (at best the same size), different lithium battery voltage should not charge the MP3 player directly above. Such as the battery voltage is 1.5V home and the purchase of the battery voltage is 3.7 V, then they must be connected to the middle of a step-down IC, so s to ensure that the circuit will not be burned.

Note that to prolong the maintenance of lithium

We need to stress, MP3 player, use in their daily care and maintenance. If you buy a new MP3 player, then three times before the charge commonly called an adjustment period, more than 12 hours should be sufficient to ensure full activation of the lithium-ion activity. Although there is no memory effect of VGP-BPS10 battery, but there is also a strong inert, should have the full activation can not be guaranteed to be used to achieve the best performance.

When the environmental temperature reaches above 35 ℃, rechargeable Lithium-Powered will not take as long as usual, when the ambient temperature to 4 ℃ below, also appears to reduce the use of time, situation now is better not to charge the battery. To play the greatest performance of lithium batteries often need to use it, so that the lithium-mail is always in motion, if you do not often lithium electricity, must be placed shade to reduce the speed of passive reaction and a charge in advance, to prevent the battery due to excessive self-discharge, which led to excessive discharge, reduced life expectancy in the Conditions permitting, the best lithium batteries once a month to “reject small shallow filling.”

“The phone is run out of battery! There were no solutions here!” In the delayed take-off flight, a passenger holding a head of cell phone power scratching frustration. This reporter has learned that in many cases, the aircraft to the terminal were not even meeting to provide support to the power, so that part of the rush to a VGP-BPS2C mobile phone or laptop to charge passengers “watches the power of the Qing Tan.” It telecommunications experts believe that mobile phones and other electronic products and supplies more widely used in aircraft and the airport, airlines pricing power to become one of the keys to improving the quality of service.

Survey conducted by journalist

Most domestic flights without charging services

Wednesday due to heavy fog in Beijing, Guangzhou and other cities of all flight delays leaving for Beijing. One of the two planes on standby hours, a number of food shortages for mobile phones, but the emergency treatment of passengers on official business, such as ant’s wok. “Are arrested at the airport, almost two hours, I hasten to make international calls to deal with some official! By phone can not solve the problem because many 40Y6797 materials and contact lists are in the Ah phone! ” One passenger said the plane without requiring equipment may also not be off the plane, only interested in filming.

Passengers reported that flight attendants can charge their cell phones, but flight attendants have regretted that, due to the voltage and frequency are not the same as the power of the aircraft can not be charged the passenger’s mobile phone. According to the flight attendants put in place, in addition to individual flights, the airline is currently the vast majority of their flights were unable to recharge their cell phones, “because these are all requirements of the United States and europe, its orbit is not the same voltage and frequency modulation, forced to load flights that will damage or cell phone.

Currently, most domestic flights, even flights of very senior business class airline, but will only provide power to charge in an emergency only. In the high-altitude aircraft to provide services may charge a little bit extravagant, but said that passengers in the airport terminal, in addition to the VIP room, charging is also very difficult. Wong, air passengers, senior told reporters he had on several occasions in the Beijing airport, a cell phone charger for charging failure, “I do not know, it’s a bad charger n has not repaired or for other reasons. ” And because the airport terminal and the shortage of electricity, the VGP-BPS2B power plug is also very little, very often, although coverage of the wireless network must be perfect, passengers will not be capable of using laptops.

Fortunately, some of the premium airlines domestic and international have been aware of this problem. The journalist interviewed a passenger aircraft German said that European airlines first and business class at the bottom have the power. “Providing passengers to provide feedstock is technically no problem.” Although experienced observers Telecom Xiang Gang Li also told reporters that the Air China flight to fly to the United States, mainly for passenger with food, Hong Kong Dragon Airlines international flights are also similar services.

Expert Advice

Airlines can provide payment services

3G era arrived, cell phones more than just voice communication, but also under video, listen to music, transforming the Documents tool. Not to mention the air has become an important place in the ‘laptop. Therefore, in charge of aircraft and airport access services are increasingly important. “One industry analyst of the case to the press. In the VGP-BPS9A/B long flight, using a variety of electronic products to take advantage of multimedia to relieve boredom, or continue to use the high end phones and business laptops to handle the paper work of many fly Keystone habits. The habits and planes at the airport and even the contradiction between the disadvantages appear to load up.

Ultimately the way to solve the problem? Insider’s commentators believe that the contradiction between supply and demand in all areas to solve the same way as paid services is a very realistic approach. Commentators believe that airlines and airports label price may provide pricing policy, so it is necessary to measure the freedom of user choice.

In addition, observers also believe that because of the increasing number of domestic flights, blocking the air breathed air traffic control has become increasingly serious, and to avoid the dilemma described in Article beginning of frequent occurrence, each aircraft must be equipped with at least one to two power outlet. Of course, the dilemma does not charge VGP-BPS10 exist in the aircraft. With the Wuhan-Guangzhou line at the beginning of comparable aircraft, high-speed trains will become increasingly popular in China. So, they are packed with white-collar business high-speed train, it should also provide enough power to allow mobile phones to communicate, so this laptop continue to work, it is useful to people seriously relevant factor .

Singapore Airport Why blocks any power?

Mobile phones, laptops, MP3, MP4, PSP games, e-book … to transport a large number of electronic devices, “night” will no doubt take the load to the airport, a high demand for services. But it is interesting to note that, according to telecommunications experts, Xiang Li Gang introduction, despite the BTP-43D1 Singapore airport design may be the most luxurious in the world, the airport service is one of the most perfect but this is the most advanced airports in the airport of feedstock are “locked” up does not allow the use of. Why is this case? It turned out that Singapore is very small, inexpensive and high-speed trains and airports have improved the coverage of broadband, many people actually turn dedicated high speed train to the airport go to the free Internet access. In consequence of this approach, “rub net is a lot of people, the Singapore airport, but take one careless move and will be open free to use food are all sealed

Used in fast voltage control load to avoid overloading the internal methods of detection, most common are fixed, temperature control and more control, or mixed-use three ways.

1. Constant voltage control

When the battery voltage is detected at a voltage almost bit set to stop the charge. This approach is the easiest way to know that as the characteristics of the Laptop battery in the battery voltage curve upward, you can detect the voltage to the nearest filling when the quasi-saturation space, different styles of recharge battery when the voltage is almost saturated like the old and new batteries are not the same characteristics, using this method can not put more ideal tension. Although this method is simple but also very dangerous, said earlier, temperature is higher than the battery voltage and reduce current load will be raising the temperature of the battery, so it may have been perceived the battery voltage has not yet reached saturation, but the quasi-set position, and the battery charging voltage does not increase after saturation began lower and thus the consequences of overloading is very serious, if it comes with an internal short-circuit the battery charger is not able to protect the circuit, once the current consequences are too dangerous would be unthinkable, so this way during charging, the user should take note.

2. The temperature rise control

Battery charge generated during the oxygen saturation in the cathode of cadmium oxide and heat of reaction, the battery temperature begins to increase rapidly using this phenomenon to detect when the temperature reaches a certain extent, both the end of the load. In the same amount of charge under the current load plus the increase of the higher temperature, so if the load current is too large to meet the set temperature of the 40Y6797 battery may not have been saturated, but the current if it is too small, then oxidation to absorb quickly the temperature does not increase significantly, the charge movement was to continue but can not terminate. In addition, this approach will be affected by ambient temperature and can determine the battery temperature is in the self-product of chemical heat, or the environment caused by the heat of denial of justice, so this method in a high temperature environment will be charged absence of a cold is too cold.

3. Control

Charging the battery voltage increases as capacity increases load when the load capacity to reach saturation, the voltage rises to the point, and instead began to decline slowly. Enjoy this voltage drop characteristics can be used to control the voltage charge termination shall be when the drop was not more demanding, typically 1.2V nickel-cadmium batteries will be 20mV of its decline is almost complete (the actual size of data May refer to the VGP-BPS8 battery) in the process of charging can be clearly observed count Out. curve of charging voltage of battery is charging current and temperature effects in the same load capacity, the current is higher or lower temperature, the voltage increases the margin is low, the decline is also more obvious. Current is smaller, or the higher the temperature, the voltage increased the smallest rate of decline is relatively flat is not easy to distinguish. Therefore, control methods applied fairly rapid charging years, and to avoid the influence of temperature to detect the failure, usually with the control of the temperature increase in the use, in order to avoid overcharging.

Nickel-cadmium batteries, they are saved by the use of long-lost, or have already dusk, and the first few minutes before recharging will take place and the tension is not only the filling of the case will also down then up the cases involving the termination of a miscarriage of justice charges. Control method is a better method of controlling the characteristics of different batteries can still use the features of the batteries fully charged issues, the comparison does not need to worry about voltage control or adjustment the temperature function and damage the battery.

Currently, computer advanced many controlled chargers are the use of such control, and the price is expensive than ordinary chargers, and some of the reputation of the name even if, in fact its control programs and the load circuit is not their design, have tended to have misjudged the situation, rather than the battery charge enough to cook an egg, which is not even enough to strike are not yet sufficient to determine the battery was full, so better a charger in addition to increasing the temperature beyond the control of, and then under the non-recurring charge, voltage and current size evolution, calculate the load capacity and to determine if the VGP-BPS9 battery has really reached the saturation point.

The three methods are fast charging method, after loading, depending on the characteristics of the battery self-discharge, usually on the battery to continue to impose a small surcharge to offset the current battery leakage underway, and the speedy and can not be be able to achieve one hundred percent guarantee that is fully charged, charging a small current to continue to fill gaps in just to fill the building. usually about the size of the C / 20 ~ C/40 additional current between the general use of the fast charge mode the charger to recharge the battery to terminate after all Kangjing OK to enter what is called the slow charge mode Indeed, that is, as a small current to continue to supplement battery charging. In this mode, the small current is almost not let the battery produces little heat, not letting the tension is much change for shippers are almost always intended to complement the purposes of collecting and will not stop not automatically, but not yet as to the apple A1022 battery battery caused by overloading, but to avoid increasing the crystallization behavior of nickel, users always have the discretion to add time of pricing.
