Today, surfing the Internet and found another on the meter replacement circuit 9V supply, and now extract as a reference, it can be said that I saw the simplest circuit, and we can try. VGP-BPS9/S VGP-BPS8A

Always felt that replacing the circuit very well, because the battery is not sustainable, because the multimeter, many from the walking tour, but since the bifurcation need to compare a lot of time to stop, so wait free time, consume much energy the battery is not sustainable. Before I had a circuit using 1.5V battery, there are good times we forget to turn off, wasting a lot of energy, the battery is very durable, no electricity per month, so in exchange ‘9V laminated battery is even better.

The Party of origin as follows:

1. Circuit works

Alternative multimeter power supply circuit in Figure 1. Circuit consists of transistor VT, step-up transformer T, the diode VD, a capacitor C and GB be composed of five elements. Transistor VT and step-up transformer T is a feedback oscillator transformer when the output power to the load current is exceeded, the transistor base current VT adopted, the oscillation circuit on work, on the contrary, he n ‘there is no current basis, the current consumption of the battery is not therefore the circuit without power switch.

Power PCB according to the size of icons with Daoke legislate, not perforated, all components can be soldered directly on the Dell Latitude D500 battery  Dell Latitude D520 battery copper surface. The battery installed on the circuit, its positive and negative effects on the P-Cu film with the flexibility to make a clamp, welding the corresponding position in the printing plate fixation. Shell with the size of the battery cell is similar, but can also be directly installed in the meter box.

The circuit is completed and fully verifies the correct welding, you can debug electricity. Firstly, the output terminal connected to a voltage of 3 kΩ/0.125W resistance, the dc voltage with range multimeter measures

Use rechargeable batteries for laptops, one of the advantages of the desktop, it can greatly facilitate a variety of environments using laptops. Introduced the first battery is nickel cadmium VGP-BPS8A VGP-BPS9A batteries (NiCd) battery but has a “memory effect”, each charge is required before the evacuation, very easy to use, and soon found himself nickel-metal hydride battery (NiMH ) replaced, NiMH not only failed to “memory effect”, but can do more per unit weight of 10% of electricity. The battery most commonly used is lithium-ion battery (Li-Ion), it is also ineffective “memory, compared to NiMH per unit of weight gain more power, the price two times higher than the NiMH . In the same weight, these three kinds battery is 1:1.2:1.9 ratios.

Notebook batteries currently used in three main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium, they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium-ion battery LI.

The purchase or replace the battery when the laptop for many users, “battery” may be unfamiliar. At the outset, batteries and batteries are two concepts. A battery is composed of several slightly bigger than your thumb, cylindrical, up to about 7.8 cm, the voltage is 3.6V small units, a professional name that is called 18650, Sanyo and Samsung is the first manufacturer in China. Batteries as a small battery, thanks to the combination series, that is, we see that the battery a. Then talk about how to determine if the battery is several nuclei: IBM ThinkPad T41 battery  IBM ThinkPad T42 battery

One way: Disconnect the battery for the number of contacts to see, there are a few tens of cores. But it is a “minister” approach. Let’s take a look at “Cao Chong” is how, “said the elephant”: the look of your battery nominal number of v, such that 14.4v, then divided by 3.6 to 4, then turned out to be four batteries together in series. And then take a look at the capacity of the battery pack, for example 4400mAh, then prove that the two aforementioned sets of batteries in series, because the battery capacity is low for 2000 — 2200mAh or more, and together the two groups can be achieved must be 4400mAh. In both cases, the battery is 4 × 2 = 8 cores.

The composition of laptop battery

Notebook battery from the shells, printed circuit boards and batteries belonging lithium ion battery. People talk about batteries in general refers to the number of batteries in the battery mAh refers to the ability of the laptop battery. Dell Inspiron 1526 battery  Dell Inspiron 5100 battery

Mainly by the protection circuit (or the secondary circuit protection), and the capacity of the circuits in two parts, the laptop battery charge and discharge management and safety.

Time Laptop Battery standby mainly by the value mAh decide. Under normal circumstances, a little more battery, the mAh value is greater than longest standby time. Battery life for notebook mainly by the charge and discharge times to measure the quality of the products is generally eligible to 500-600 times. Therefore, efficient use of laptop batteries within two years expired the 361742-001 371785-001 battery is aging, standby affect the strong decrease of the mobility of laptops.

Abstract:

Most laptops today use lithium batteries, in which over 13 inch notebooks, especially over high capacity 6-cell battery, while the 13-pad of thumb to ensure portability, Many products have chosen the 3-pin thin around the battery. To get the most battery life of portable, many manufacturers have started to develop fuel cells, I believe that sooner or later we can see the production version of the fuel cell, then you really can-office Portable Meteorologica lPA3395U-1BRS PA3399U-1BAS

Sony hopes that the new TV-compatible 3 – D can be achieved television half of sales in the last three years he has sought a detailed support their sagging business.

Hiroshi Yoshioka, Sony’s Executive Vice President and Head of Consumer Products and equipment of the group also said the company is in talks with several car manufacturers to enter the huge market, but filled with lithium – ion car. He has not the name of the car manufacturer. Much of the investment of 100 million U.S. dollars in VGP-BPS8 battery technology in the coming years will be used in car batteries, he added, Sony has also increased in this area of employees.

Sony 3 – D-TV and video-game demonstration in October.

Details contributing to the formation of an overall strategy on Thursday, offered last week in Japan, Sony are planning to rely heavily on technology, and 3 – D-line content to an operating margin of 5% to achieve the fiscal year 2013 to year ending in March.

Sony has announced that sales have more than 100 trillion yen (approx. $ 11.4 billion), three-dimensional aspects of products such as televisions, DVD players and game consoles objectives in this work. The company plans to introduce a 3 – D-compatible TV for the next year, Mr. Yoshioka said that today the nature of the collection make 30-50 percent of TV sales at the end of 2013. This VGP-BPS8A technology can help you choose the audience to see, in the current model, two-or three-dimensional aspects of the television special glasses.

Sales depend on the existing 3 – D content, Mr. Yoshioka added that he saw great potential in video games. Sony says that these models 3 – D-TV will be priced at a premium, but there are the glasses is the most expensive Sony, but as the actual production of television.

In the battery, Sony plans to play for the safety of the product. Mr. Yoshioka, batteries, the company has developed because the battery has in the past Sony to create a safe product. Sony and many other recent cases, to a battery of consumer products such as laptops subjected caught fire.

Sony believes that the battery market is enormous and the prospects that it would make, even if the current behind other providers. “We have plenty of space, said:” Yoshioka. Sony said that there are currently around 2,000 employees working in the field of batteries, but plans to increase this figure.

Vice President Howard Stringer, Sony shaking in society by deficiencies in the content and software companies, high costs for the troubled production. It expects an operating loss of 60 billion yen (approximately USD 684 million) this fiscal year, but Mr. Stringer said the company’s efforts to balance, by reducing costs and other activities.

In comparison with other secondary batteries, lithium-ion batteries with excellent performance are widely used in mobile phones, laptops and other electronic products. The use of the process, noting what is important is perhaps our greatest concern. To this end, we must listen to the opinions of experts and suppliers.

Laptop Battery Conservation Strategy

Many people use laptops were used for piloting an external power supply, but such use would damage the battery or even unusable. The reason is connected to the area after the laptop battery will be automatically debited, which is actually equivalent to a daily part of the battery charge and discharge, thereby affecting the battery life. I often use the power of work when you remove the battery.

If the long-term use of external power, the use of 1 week (up to 1 month) should be a full charge and discharge, so that can repair the control system of the battery (register) Lane n ‘ was not in use, but may charge a nominal capacity of control and consistent fact throughout the charge and complete discharge to calibrate the battery chips. This is preferable to make the battery removed.

Founder of mobile technology products development, product engineers, Cao-ping said that after repeated load, the discharge capacity of lithium-ion batteries will decrease, the decrease of battery capacity in the degree is directly proportional the number of loading and unloading.

Newly built lithium-ion battery, only charge about 50% of capacity, the new laptop batteries as well. Used for the first time that I need to put the power to do, then an external power supply is fully charged, but the first charge preferably exceed 15 hours. Secondly, we had to wait three rechargeable battery is worn out, charging time to over 12 hours.

Many providers, such as the Founder of the laptop power supply circuits and the battery itself, are designed to load and unload circuit monitoring and protection, battery power will be monitored through the surveillance system , consumption below the value set, the device will issue a warning, then May be to charge the battery.

CAO Guo-Ping said that not long term use of batteries in stock before they must be charged or discharged battery to about 40%, then placed in 15 to 25 degrees Celsius dry preservation interval of 3 months to remove the checkmark from the battery to prevent battery discharge too bad. In addition, under normal circumstances, the battery is full, the system will automatically cut the load circuit, seeing the machine to move the eradication of brilliant. If the VGP-BPS8A battery-charging, the battery temperature will increase, so that excess energy, gas internal decomposition of the electrolyte, causing the battery internal pressure increases the risk of spontaneous ignition produce or rupture. Therefore, Founder Technology has been to recall the client, laptop battery must be charged on the original machine, to prohibit the use of third party shipper or other models of laptop charging, in order to avoid unnecessary risks.

Battery for joining the same direction that development is always environmentally friendly, safe, lightweight, and the same amount of space for greater storage capacity. On current trends, the laptop battery is still the main application of lithium-ion VGP-BPS8A battery, fuel cell is most likely to replace current lithium batteries, but the status of ongoing development, may also need several years of ‘efforts and solar cells on the more environmentally friendly, but because it is the output voltage and power are too small, such as application backlog will have to wait before the next breakthrough technology widely used.

Samsung Mobile-related person in charge, said: impact of the life of lithium is an important factor in the number of loading and unloading. Therefore, if the batteries used frequently, the time the battery will decrease quickly. In daily use by the process, pay attention to, without the battery when it would be better off, while minimizing the number of battery charge and discharge in order to ensure that long-term battery, a effective use. High current battery charge as long as does not exceed the rated voltage, the impact is minimal. Samsung quick charging technology is portable VGP-BPS8B battery as possible within the limits allowed by the growing tension, the pricing, if time is short compared to other brands of computers advantage of charging time is obvious. The depth of discharge is usually used when time does not use the battery is good, if not the depth of discharge will affect the frequency of battery life. If the short-term need to maintain 50% of electricity better.

Although the Li-ion battery memory effect is not obvious, but not always operate to food after the proposed charging, the battery is fully charged, after a laptop generally has a detection circuit automatically stops load, it is generally little impact. It should be noted when used frequently or not to charge and discharge the battery, once used, a full investigation, the lowest frequency of use, battery life longer. The direction of future development of the main battery is a high cohesive energy, high-capacity portable. Samsung is also developing a variety of concepts VGP-BPS9 battery products, particularly fuel cells developed quickly, hoping in the near future may be applied to laptops from Samsung to offer users a better experience and more practice.

To reduce the hardening of the battery to extend battery life, we must first improve the working conditions of electric bicycles. Reduction of body weight, getting rid of unnecessary decoration pieces, the appropriate speed limits, does not weigh very long when you do not use electric bikes to add to the burden is better able to recharge after each discharge and not under-voltage protection and to guard against VGP-BPS8B battery over-discharge protection for a minimum of 24 V rated voltage must be located at 21.5V ~ 22V, 36V nominal protection to a minimum voltage must be selected 32.5V ± 0 , 5 V for a nominal 48V to be located at 44V ~ 45V. The tension on the renewal of such a line capacity is only reduced by less than 2 km, but it may actually prolong the life of the battery. Every three months on a regular basis and not the professional maintenance of cells in repair and recovery in time. The method is simple, the economic cost is very low, but there is some difficulty in complying strictly. Thus, you can use specialized equipment for maintenance of desulfurization, these methods are:

1. The use of office equipment desulphurization fast

Desktop rapid desulfurization devices works is a high voltage, high pulse load current through the elimination of a negative amount of sulphide block wear. This method is fast, fast, get a temporary suppression of the effect of the treatment, but the high voltage high current can blow desulfurization may also reflect the active substances, including the elimination of lead sulfide in the positive plate to severe dehydration and softening problems, fatal damage to the VGP-BPS8A battery through the equipment in more than two sulfur base will be discarded after the battery. In addition, the current point for an addition to the professional maintenance of the basic fee of sulfur in 60 to 80 hours, up to six months, the life of the battery and is not the User substantial economic benefits. Currently, the battery on the market to maintain professional traders must understand the dangers of this approach. As a result, became the desulphurisation equipment discharge pulse, in effect, a fundamental principle has not changed is only the constant current in high voltage transients Hengda peak pressure, or will it damage the electrode active material, used friends of these products must be very clear on this point.

2. Options for desulfurization Chargers

In addition to battery charger sulfur is currently available in three works, one of which is similar to office equipment desulphurization fast mode of operation, using high voltage high current pulse load, blocking the desulfurization wear negative above indicated that this method of battery life would be a mortal wound, was refused by the market. The second is used fast pulse edge of the charge and discharge pulses, the use of peak instantaneous interfering with the collection process of vulcanization of the battery. The other is cyclical, with 10% to 20% over-charging method, to restore the battery to lead sulfate crystals. Both chargers can be added when the sulfur in the feed, but it will result in less load, or overload, but also ignored the procedure for discharge of the  VGP-BPS8 battery is the fact that most process drying, if the result is not satisfactory, the majority of users The charger is equipped with electric cars would leave after such a duplication of investment in desulphurization methods.

3. Use the online lead-acid battery extended life support

On the online extension of life support-type lead-acid batteries and battery in parallel, can be 24 hours to prevent and eliminate sulphides. This method is slower restoration, repair time is quite long, often more than 120 hours, but both charges discharge process is also capable of preventing and eliminating the healing, repair works. Because low voltage and low voltage, prolonged life support does not exert a strong impact on the battery plates which leads to dehydration and mitigation, which is a user input can be validated at the track maintenance , especially for the quality of the new battery can extend the battery life of 2 to 5 times, and entry may be accompanied by an electric motor, the next time to replace the battery, extending the life support can also continue to be used for users to save considerable economic costs. If a user once a year to replace the battery, a battery 280, the user 10, spent 2800 yuan should replace the battery on the conservative calculation, if you use extended life support twice the length of battery life of 10 years, can also save about half of the battery is charging.

To adopt this approach very significant. Firstly, the user has brought tangible economic benefits, reducing the user of trouble. Second, it enhances the reputation of the warehouse, provided that the conditions for expansion of production. Thirdly, to solve the battery electric vehicle warranty dealer is very hard to reduce complaints, improve credibility and increase the point advantage at the same time, in-store sales also increased to promote programs of commercial marketing. Fourthly, we can greatly reduce the demands of the VGP-BPS13/S battery manufacturer for the reasons. Fifth, improve the image of electric bikes, electric bikes to expand the overall market development. Sixth, improving battery usage, there are environmental.
