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.

 

2. Selection of components and installation and implementation IBM ThinkPad R40 battery  IBM ThinkPad X60 battery

 

VT-type PNP low power transistor, such as 2N3906, β> 200.

 

VD: 1N4148-type diode switching.

 

C: 1uF/16V.

 

T: step-up transformer, using Φ10mm magnetic ring as a framework, the primary winding L2 Φ0.15mm enameled wire around the 16 laps, the sub-L1 with Φ0.08mm son enamelled winding around the 140 laps. Around the system before using the plates of plastic or bamboo is a small shuttle. Cut each end of a small crossings, the enameled wire around the shuttle, then re-winding.

 

Multimeter offers alternative supply printed circuit of Figure 3. 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.
