Raise three times the power zinc-air battery is about to enter practical

Monday, December 28th, 2009

Norway’s SINTEF research institutes hope that the next launch of zinc-air rechargeable batteries, so that the use of oxygen in the air as the cathode active material, with more than century-old battery technology really came to the public side. A few days ago there has been news that the U.S. VGP-BPS2 battery maker Energizer Energizer also intended to promote the zinc-air battery, but their products are one-time non-rechargeable batteries.

Energizer said that in recent years in zinc-air VGP-BPS2A battery technology research and development to obtain significant results, mainly by improving the intake air volume control technology that allows the battery to enter into sufficient oxygen react, but do not attract too much oxygen affect the life span. At the same time, they also improved the battery to the ambient temperature and humidity flexibility. Is alleged that the zinc-air battery in the same size, the capacity of the existing alkaline batteries or lithium-ion batteries 3 times.

Energizer zinc air VGP-BPS2C battery for the rectangular design, the surface has opened a small hole into the air, the factory closed, when the use of labels. A user opened a tab to get started, but the inevitable, their life will start from this point begun to deteriorate. Energizer said they have received 30 OEM manufacturer of support from the next summer, starting the use of zinc-air battery products, including wireless keyboards, Bluetooth headsets, remote controls, handheld media players, mini-flashlight and so on. The Energizer’s first zinc-air VGP-BPS2B battery will also be available next summer, the first for the PP355 specifications, size 32.2.14.7×4mm, voltage 1.5V, capacity and existing AAAA (9 Hao) battery the same as the price will be and their disposable lithium battery.

Matsushita developed a large-capacity lithium-ion battery

Sunday, December 27th, 2009

Japan’s Matsushita Electric Industrial Co. Ltd. has developed a new type of lithium-ion battery, with a capacity of 4 Ah, can be applied to electric vehicles, laptop computers and other devices.

According to Japanese media reports, the Panasonic battery using nickel material as the positive and negative silicon alloy is used to develop such a large-capacity Cylindrical Lithium-ion batteries, with a capacity higher than the existing products nearly 30%.

According to reports, the lithium-ion battery can be connected into the module to act as a power source for electric vehicles or household batteries. This new battery connected module, which can be a single charge of electric vehicles to extend the life mileage of about 35%.

Lithium-ion battery is currently the number of mobile devices an indispensable power. Compared with other energy storage systems using lithium-ion battery power-storage system features a lightweight, high-capacity and other advantages, its prospects are generally good. It is reported that Matsushita expects mass production in 2012, this lithium-ion batteries.

A wide range of batteries are not universal

Wednesday, December 23rd, 2009

With the shape of the vastly different notebook computers, batteries to cater to its shape change, there are rectangular (like bricks:)), cylindrical type. Since the Sony laptop  battery there is this difference, so they can not be universal, and sometimes even the same family are not into. Such as the IBM X2 and the X3 series. Moreover, many placed the location of the battery are also different, and sometimes can be done when the notebook’s feet with.

The size of the pool size is directly related to the use of laptop time. Its size mainly from the marked mAH battery mAh) and voltage multiplying the results of a few volts to judge. Battery life is not solely determined by the capacity of the sony VGP-BPS2  battery with the use of the environment and hardware configurations are closely related, and how many batteries are also related to the general number of the battery core 4-6Cell, batteries of the same Under the batteries more than the capacity of the battery, the more natural, less batteries, the battery capacity of the naturally less. That said, the battery capacity, we have to look at some additional features battery. If you are Samsung or a DELL laptop user, you may notice that their battery will have a row of small lights, when the press next to the push button, a small light will stop blinking, you may not think that this is only a battery ornaments It is a role is used to display the sony VGP-BPS2B  battery capacity, it comes from the first creative player. Some low-cost LCD display Walkman absence of windows, so we used the same methods with which to display the remaining battery capacity, which do not boot, remove the battery capacity will be able to understand the function, I feel very convenient. Now only DELL (L400-era began), Samsung and other models used a small amount of this approach.

In addition, we should not ignore the weight of the sony VGP-BPS2A  battery, which directly affects the laptop’s overall weight. Ultra-thin machines generally small in size and the battery would be more, rather than the relatively large number of mainframe, which will be more on batteries, such as the above to see a full range of IBM battery.

Laptop plug-in battery case

Wednesday, December 23rd, 2009

laptop battery from 3 to 6-pin or 8-core-core, from 23 to Qi Babai hundred or even thousand dollars, usually normal use of the life in two years or so! This notebook computer users is a big loss!

If we can designed a notebook computer plug-in battery pack, you can use regular V battery-powered, it will be a good choice!

This battery box, there are two design ideas:

1 may be based on different models of dell C1295 battery is designed to correspond to the size of the laptop when necessary to replace the proprietary batteries, open the box, you can put a specific amount of 5 batteries.

2, can be designed into a real plug-in batteries, is equipped with the same laptop power adapter plugs directly into the notebook DC power interface.

Laptop DC voltage is generally between 12v to 20v, current at about 1.5a. General six-cell battery power in the 4800mah. General 5 batteries (rechargeable type) voltage of 1.2v, city, price of 16 yuan a. This is equipped with 10 such as rechargeable batteries, also 160. Even if the life expectancy, replacing them can accept! More importantly, such a dell GD761 battery is readily available to sell! If we are in special circumstances, but also with ordinary non-rechargeable batteries temporary spare!

By design, the only technical difficulty is the battery box must be configured to current control circuit (chip) that can provide the necessary stability for notebook current! It takes another configure a dedicated charger, or directly converted to use laptop power adapter comes with charger!

How to grasp the laptop battery charge time

Tuesday, December 15th, 2009

Laptop battery charging time to pay attention: in the end laptop battery charging time is right to be how long? In the battery charging process, we only have to take what? Charging time will affect the amount of sony VGP-BPS2 battery life then? Here we have laptop battery extended some of the problems encountered in open, take a look at the most vulnerable for the notebook battery what could be attention.

    Rumors of a laptop battery: a new battery charge and discharge cycles should be a way to activate the battery performance.

Truth: This argument is not a rumor exactly. Because some laptop batteries from the product to the customer’s hands will be after a certain time lag, the short is one month or as long as six months (of course, Pai brand batteries network is not the case, and they are generally real-time production of the sony VGP-BPS2A battery,sony VGP-BPS2B battery, so that is the reason why they can occupy the international market reasons). For the longest time, the battery factory, the electrode materials will be passive, so the manufacturer’s suggested initial first charge the battery on the notebook is best for 3 to 5 times fully charge and discharge processes in order to eliminate electrode materials passivation, to reach maximum capacity. However, the charge and discharge are talking about here does not mean that the depth of discharge, but a shallow discharge. There is a laptop battery charging time to grasp a problem, you can go to Pai network card customers to inquire about the battery.

Laptop battery rumor 2: When a new battery buy it back later, the general will agree that: The best three times the battery charge and discharge cycles, and the laptop battery charge discharge time should not exceed 12 hours in order to activate the battery maximum effectiveness.

Truth: Ni-MH battery in order to achieve the most perfect saturation, need to go through “complementary” and “trickle” process, this time, generally about 5 hours. At present, lithium-ion batteries, “constant”, “constant voltage” charging feature is its deep-charge time control at 4 hours. Once filled, the battery’s internal protection circuit will automatically stop charging, so this approach is unscientific and has no practical significance.

Some people have been tested using a mobile phone: in use the battery charger travel charger is full, the switch to Charger battery charger to confirm the degree of saturation. When he discovered Charger charger is still charging the battery, they think that the battery has not yet reached saturation. In fact, this lack of rigorous testing methods. The reason is that the indicator light is not detected Charger Charger saturated or not, the only true standard of reference voltage charger Charger cell phone does not necessarily mean reference voltage, so when the phone that the battery reached, Charger Charger may not think so, still charging, but is filled in, the only of its own know. So long as we charge in accordance with the requirements of the specification can be, and to extend notebook battery recharge time is just needlessly waste of time.

Laptop battery rumor 3: As long as laptop batteries used properly, it will, within a certain period of circulation appears best to achieve maximum capacity. For example, the early nickel-metal hydride, nickel cadmium batteries, if used properly, regular maintenance, will be 15 to 203 cycles points to reach its maximum capacity (factory capacity 1200mAh Ni-MH battery in the loop 120 times, the capacity may be to 1200mAh).

Truth: It’s a battery in the Japanese products are more common technical specifications in its cyclical nature of the book can often be seen in Fig. However, the current mainstream of lithium-ion battery, this cycle peak phenomenon does not exist. Because the lithium-ion batteries from the factory to the scrap, with a capacity less performance for the circle time, never had the capacity rebound phenomenon. Maybe have a friend who will ask some ThinkPad notebook users through the deep discharge, you can restore the battery capacity. In fact it is only testing the software error detection only, the battery’s actual capacity did not improve. The right sony VGP-BPS2C battery factor is the temperature of their environment, of course, laptop charging time there is a certain relationship, but still inferior to the environment. Lithium-ion batteries in the end there is no best state? The answer is yes, it suffered with the ambient temperature change. Under normal circumstances, lithium-ion batteries in 26 ℃ ~ 41 ℃ environment would show excellent performance. By low temperature or high-temperature state, its performance is being reduced. For example, according to your outdoors in direct sunlight using a laptop computer cases, there is no longer in the indoor use.

Laptop battery rumor 4: 2 nominal capacity of the same (for example, 800mAh) batteries, if an actual measured capacity of 860mAh, the other is 805mAh, so 860mAH’s definitely better than the 805mAh.

Truth: In general, different models (different sizes) and lithium-ion battery, the higher the capacity the longer the time used. If you set aside such factors as size and weight, of course, is the capacity the better. But for two nominal capacity of the same (for example, the example above) the battery may not be. Since the actual high capacity battery that is likely to add in the electrode materials used to increase the initial capacity of the material, reducing the stability of electrode materials used. The result is shown in dozens of cycles, after the rapid decay of high capacity piece, while the capacity is still low strong. Many domestic firms in order to reduce costs and expand sales, often on the use of such tools to produce high-capacity battery. Users will find that six months after the use of working time is much shorter. In short, to improve capacity at the expense of sacrificing cycle life, battery makers are not material up and down the article, it is impossible to truly improve the battery capacity.

Laptop battery rumor 5: If you do not use rechargeable batteries, should shine of the electric re-save.

Truth: In fact, not only are the above-mentioned rumors, lithium-ion batteries in the end that was full of preserved or preserving the shine is sure to make a lot of people confused? Answer to this question from a congenital defect of their talk, that is “aging effect.” Lithium-ion battery in storage for some time, even without the use of recycled some of its capacity will be a permanent loss, because the lithium-ion battery anode material from the factory is started when the failure of their journey. Different temperatures and the saturation level of the range is also different under the age of the specific range can be seen in the table below.

Thus, the higher the storage temperature, the battery charge of the more full, the greater the magnitude of capacity. So for long-term preservation of lithium ion batteries, the user should be controlled at 40% of its electricity and stored at 15 ℃ or lower temperatures can be. For those nickel-metal hydride and nickel cadmium batteries did not exist in this “aging effect”, after the long-term storage in just a few full charge and discharge can be restored to its original capacity.

Laptop battery rumors 6: laptop battery recharge time is generally controlled, for the laptop battery is full then, while continuing to charge the battery charge 1 to 2 hours, which would help to enhance battery saturation.

Truth: In fact, today’s laptop battery usually had a power protection circuit, full power after the battery protection circuit will automatically cut off the charging circuit. Therefore, the laptop battery charge time is a fixed value, filled with the battery after the power supply only for laptop devices, even if the battery charge for 12 hours and then it is useless.

Users can not change their own Dell laptop batteries Adamo

Monday, December 14th, 2009

Dell’s latest Adamo Apple Macbook Air laptop computer as a rival, in the thin area does have a good performance. However, this model, while maintaining the shape has become in some respects similar with the Macbook Air.

This thin and light notebook Adamo also learned that in the DELL laptop battery and the Macbook Air uses the same design, the battery embedded in the fuselage, the user can not change on their own. This means that users can not be demolished under the battery on the road, but want to get a replacement battery, the user must put laptop back to Dell.

Dell did not announce the price of dell Inspiron E1405 battery replacement and service details. The Apple for UK users to replace a 17-inch Macbook Pro battery costs £ 139.

Laptop battery repair often fails to resolve

Friday, December 11th, 2009

Most machines are all kinds of battery protection circuit, when the laptop battery temperature is too high or when the discharge current is too large, probably because the battery protection circuit moves beyond the standard, and thus causing the battery power automatically force the issue.

The most common situation is that the use of DELL laptop battery is running at full speed when the current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery, in which case do not panic, as long as the Disconnect peripherals to wait about 10 minutes, you can reboot.

There is also a common situation is that laptop computers in a hot environment, high-load operation using the battery, so that the ambient temperature plus the heat generated by the battery self-discharge battery protection circuit may exceed the preset temperature, which is particularly high frequency machine In the high-temperature environment may occur after high-speed operation. Encountered such a situation should remove the dell Inspiron 6400 battery placed in a cooler place (remember not to put refrigerator frozen!), After half an hour should be back to normal. High temperature for the lithium battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment, the use of high-load laptop. IBM in 2001 after Chupin notebook computers, power management software Battery MaxMiser can display the battery temperature and discharge current, but not every brand-name products have this powerful.

In order to maintain the BIOS state, many laptops have the battery calibration repair option, simply speaking, this function will be the notebook’s battery is full and complete discharge to no electricity, and then re-filled, so that for long-term result of not completely discharge the accumulated have a certain role in error correction. However, please note the correction in the BIOS spent rather a long time, if you do this, preferably before going to sleep.

Many models also have Windows, discharge functions. This can save time, while working will be corrected:). Battery Calibration will not be too frequent, often the depth of discharge is to bring the dell Inspiron 6000 battery life shortened, it is recommended two to three months to do it once.

Laptop Troubleshooting 4: Interface question

Laptop computers most likely failure of the interface is a network interface, USB interface, IEEE1394 interface, and headphone jack, etc. The main problem is the use of poor quality and improper operation of the plug caused mainly as a pin is damaged, interface circuit burned, the port surface rust and other coatings.
Solution: the interface pin damage is usually due to excessive force when inserting or receiving the wrong equipment, caused by, so when the access device interface, a good idea to look at whether the match, if they feel the process of access to significant resistance, then the need to look at the pins is bent, to avoid further bending Er Shi pin fracture. If the pin has been obviously bent, you can clamp off the state of its set right, remember to first shut down, otherwise the pin interface circuit short-circuit may cause fire.

Note: the port is a gateway to the external computer, not a port of the computer as a person without friends, loneliness, protect notebook port is also a important thing. Now, most laptops are equipped with a baffle port can be used, in the absence of the case should be connected together on the tailgate, and do not let interfaces encountered water or corrosive things.
