Said that the battery of a long history, the oldest VGP-BPL8 VGP-BPL8A battery in the world originated 2000 years ago, this was called “Baghdad”, the batteries, still preserved in the museum of Baghdad (today? N ‘Have they not blown?).

 

Drums There are two commonly used parameters, respectively, voltage and capacity. Voltage depends mainly on positive and negative materials. Ordinary dry cells, are voltage 1.5 V, while the voltage of the rechargeable battery 1.2V. The capacity is the capacity of each power bar, with the discharge current and discharge time of the product, said. For example, a capacity of 500mAh battery means the battery 500mA discharge current is able to use 1 hour. Obviously, if the discharge current to 250mA, you can use two hours, and so on.

 

Commonly used batteries are manganese batteries, alkaline, nickel-cadmium batteries, laminated batteries, button cells. Mn-Zn batteries, nominal voltage of 1.5 V, inexpensive, but the discharge still poor, not suitable for high discharge current, and can charge only applies to some small electronic circuits today. Manganese dry battery has a strange feature, the intermittent discharge time and the continuous discharge time is longer, it is a recipe for using ordinary Ah F4812A HSTNN-lB31 battery.

 

Alkaline batteries, the nominal voltage is 1.5V, the electrolyte is a water-soluble potassium hydroxide liquid, large volume, can be large current discharge characteristics are superior to all aspects of manganese dry batteries. In practice, the more we need high current circuit, alkaline batteries, the better they can play a role. Alkaline WALKMAN to your taste in the band used, and their longer life expectancy than the average number of batteries in the camera flash can not be separated using nickel, alkaline batteries is the best choice . Only the more expensive alkaline batteries.

 

Most cases, the alkaline battery, the words “Free” in Chinese or English, but in fact, alkaline batteries can be charged and the charging up dozens of times. Alkaline batteries can be taken only small current charging method to 50mA load current is appropriate, and most of the feeder load current was relatively large, the results of the liquid in the battery, equipment corrosion. A representative alkaline LR20, LR6 representative on the 5th.

 

Common manganese dry batteries, R alone, as the model, a common R6P is the fifth of battery capacity. Bitbaby you want to use the “white elephant” alkaline batteries equipped with branded appliances. Dell Latitude D820 battery  Dell Latitude X1 battery

 

Many calculators are used on silicon photovoltaic solar cells, it is light to the touch when the battery. Solar cells are rectangular sheet, and also the transistor type flat circle. 0.5V General each can produce the voltage necessary for several chipsets to increase the tension, several sets of parallel to increase the output current. And in general, and button batteries in parallel to conserve energy stored up, again a small charge.

 

Battery nickel is also known to everyone, without further ado. According Bitbaby know, the little Japanese back in the early 90s on the Prohibition of the battery compartment in the local production of nickel, and to protect their environment. Now the market is so much JAPAN compartment nickel comes from? Now, promoting the use of nickel-metal hydride PA3399U-2BRS PA3421U-1BRS battery, high capacity and no memory effect, but also more environmentally friendly. Ah cadmium is harmful!

Ericsson’s new diesel-battery hybrid energy solutions to reduce half of their network operating expenses

Ericsson (NASDAQ: ERIC) and the operator Celtel cooperation of Uganda, to provide a new diesel battery hybrid energy solution. The solution can significantly help local areas outside the grid covered by mobile networks to reduce energy consumption, a reduction of almost 50% of operating costs of networks. Celtel Uganda was also the first application to use the solution provider. VGP-BPL8A  VGP-BPL9

  

Celtel Uganda is the local power grid is currently being used outside the coverage of diesel base station wireless replacement of all new hybrid energy solutions Ericsson and work with base stations Ericsson radio, outdoor cabinets apply. So far, over 100 sites to achieve such a transformation. In the past, a standard base station consumes about 20,000 liters of diesel per year, while the new solution will reduce diesel demand by 50%. Be reduced and the cost of transporting diesel fuel and storage, while overall operating costs of a single base station will remain lower in the future.

 

In Uganda, approximately 50% of base station wireless must use diesel oil as main fuel. Many high-growth markets, will also be diesel main energy sources, especially those in electricity supply shortage or unstable areas, such as remote villages.

 

Traditional non-grid diesel solutions are supported by two diesel generators working alternately. Ericsson’s new hybrid energy solution, in which a diesel generator will be replaced by a battery specially designed to handle a large number of charge storage and output.

 

Hybrid energy solution Ericsson is a stand-alone power solution that can recharge the battery via the configuration storage and output to achieve the highest level, thus prolonging the life of batteries and generators.

 

Celtel Uganda, Siyabonga Zulu chief officer of operations, said: “We operate in the work of Uganda in the full deployment of the hybrid energy solution Ericsson. The solution to the cabinet to provide a reserve battery more powerful and weak energy consumption of cooling device, and to help us cut 50% of diesel consumption. energy saving effect is very important, and we will extend cost effective network for people who have never been contact with the mobile networks to provide network coverage. ”

 

Ericsson site Solutions strategic product manager for Kent Westergren said: “This kind of customized solutions for users in the market response is very good, because it significantly reduces operating costs, and reduce the impact on the network environment. Generally tend to base station because of too big to operate solely on solar energy, for those who want to reduce costs or the emergence of green operators, this solution is an excellent choice.

 

Ericsson diesel electric hybrid power solution is a series of F3172A PB995A energy optimization innovations for the latest product. Ericsson hopes that the series of products to help operators to reduce overall costs while improving mobile networks in the world in environmental performance of the growth process.

 

In 2006, Ericsson will be the last generation of WCDMA base stations to reduce energy consumption by 35%, and the breakthrough introduction of a number of alternative energies, as in the use of telecommunications solar and biomass, which makes mobile communications in BATCL50L  LCBTP03003 emerging markets is more economic, environmental.
