Filed under: Battery, battery news — Tags: , , — ecsem3 @ 4:36 am

According to Dataquest statistics ,it showed that at present there are 136 countries be in popular use of the upsurge of solar cells Sony Battery ,in the world , of which 95 countries are on a large scale research and development of solar cells, and ctively produced all kinds of related energy-saving new products.

At present, many countries are developing long-term solar energy development plan in preparation for large-scale development of solar energy in the 21st century,(all of them are trying to produce the solar energySamsung SLB-0637,battery ) the U.S. Department of Energy launched a national solar plan, the Japanese what launched is the Project Sunshine.

The United States also launched a “solar street lamp scheme” .it designed to allow the United States as part of the city’s street lamps were replaced by solar power, according to plan, every street-lamp can save energy 800 degrees per year.Japan is also being implemented solar energy “7 million units in the project,” Japan is ready to mak residential solar power generation system popular , mainly in the residential installation of solar cells Sony NP-FC11,battery on the roof power generation equipment.European researched and developed solar cells ,and they will be included in the famous “Eureka” high-tech plan, meanwhile launched the “10 million units in the project.”

Japan, Korea and Europe, a total of eight countries have recently decided to work together in Asia and Africa in desert areas of inland to build the world’s largest solar power station.it is to produce the solar cell Digital Camera Battery.

Since the 20th century, 90 years, the global solar cell battery industry go on developing at the speed of 15% per year.This shows that the solar cell Samsung SBL-1974 battery industry development have broad prospects in the countries all over the world

how we can know batteries from others?

Filed under: Battery, digital camera battery — Tags: , , — ecsem3 @ 5:49 am

In market there are three kinds of batteries for us to use generally: Nickel-chromium batteries;Ni-MH battery; Lithium battery. they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI,such as Sony NP-BG1 .

Then how we can know them from others? now we can distinguish them  from below some points :

  1. To distinguish from the battery identity , lithium Digital Camera Battery is LI, lithium-ion battery is LI-ION.
  2. lithium and nickel-hydrogen batteries Anothe is the number of charge cycles. The number of ordinary rechargeable lithium to only 400-600 times, specially modified products, but 800 times,is generally used on the scrapped two years, while Ni-MH Digital Camera Battery can charge much more than the number of necessary relative to the lithium batteries,, usually 700 or more, good quality battery can charge and discharge 1200 times, Ni-MH battery life is more longer than lithium batteries.
  3. the last difference is the place of the origin after  battery materials, the origin of the general cell batteries is in Japan, South Korea, mainland China and Taiwan Province, in particular, mostly in Japan. The more well-known is Japan’s Sanyo (Sanyo), South Korea’s LG, Samsung, and so on, the Sony NP-FC11 battery I useed is produced in Japanese.

Battery is made from the batteries, generally people are talking about 4Cell, 6Cell,it meens the number of batteries within the battery, such batteries readily are  available in the market, prices generally ranging from 10-20 yuan(such as Samsung SBL-1974from South Korea and Sony NP-BG1 ).China,Samsung ,and Taiwan Province of China  are mostly based  on  in processing ,and the core of Japan is used to  product the batteries. In the next-generation cell batteries, some already do not use such a garden-shaped batteries but do  a lithium polymer block in order to get greater power and smaller size.

Now that the price of the original equipment batteries are very expensive in market, it is around 1000-1500 in general, so some of my friends started to replace the battery with Batteries batteries to extend battery life. it is possible in Theory , but due to reasons in process, the batteries are generally used the ultrasonic welding, there is no gap,and  it is difficult apart, even if the hardware is also very difficult to disassemble a close, and some camcorder batteries ,such as Samsung SLB-0637 ,there is an internal battery protection circuit, the event of the internal temperature is too high,it  will automatically cut off to protective battery, if the piece of the circuit are damaged when replacing the battery , Consequences would be unthinkable. So I still do not recommend to replace batteries by yorself, even if the need to be replaced ,you should look for professional and technical personnel to assist the replacement.

The use techniques of camera and camcorder rechargeable batteries

Filed under: Battery, digital camera battery — Tags: , , — ecsem3 @ 5:44 am

There are four use techniques of digital camera and camcorder rechargeable batteries,as following:

  1. the preservation method of Ni-MH battery: removed the nickel-metal hydride batteries not to use for long-term from the appliances, full of power and then stored. Otherwise,if you have not uesed them for a long time, you will find that the battery has been bad, when you begin to use them.the reason is that the excessive discharge of the battery,for one thing, the Sony battery.
  2. how to charge for the new nickel-metal hydride rechargeable Sony NP-BG1 batteries ? First thing to say is to use a new battery before, firstly to  charge or to discharge ,it depends on what you are charging. If it was  to charge slowly,you can first charge the battery , and the charge time can be longer than the normal charge of some, and thus it is beneficial to activate the battery. But if you were using a fast charge (in particular the use of no protection to prevent overcharge and over-temperature protection devices such as other fast-charge ), it is best to discharge firstly ,instead of charging. To simplify operation, no matter how we charge or the battery production date, we have better to  discharge and then recharge it, so it is beneficial to the battery,whaterever it is a  brand-name batteries (such as Samsung battery)or general.
  3. The complete charge-discharge cycles should be taken to ensure, when using the Sony NP-FC11 battery each time,which is fully charged before use no electricity to recharge, so it  help to reduce the battery memory effect,and extend battery life and maintain performance. In addition,we should avoid re-interrupted.the charging process . We usually have such some bad habits, such as when charging battery ,unplug the charger to see how hot the battery, charger and then plug back then. This usually will lead to apppera instability in the charge cycle, the battery can  re-start a full charge cycle, but in front of the charging cycle has completed. Charge cycle of instability will reduce battery life. Of course, even brand-name batteries is no exception,take for instance the Samsung SBL-1974.
  4. In selecting the fast charge and slow charge, of course, slow charge is better (although we  have to wait for 15 hours or so),the damage of slow-charge is smaller than the fast-charge , and the price of slow charge is cheaper. The pursuit of short-term charge, we can choose to use smart fast charger (take Samsung SLB-0637 for example,of course, the prices is higher), using an appropriate smart charger, some Ni-MH battery is fully charged a few hours in , and there is no damage to it , battery life would not be greatly reduced. Because a smart charger with a microprocessor-controlled, with automatic stop filling (to prevent overcharge), thermal protection and trickle charge and other functions, usually decided when the battery is full of electricity, and then fully turned off the charge or the steering trickle charge according to the design of different, .

The experience of buying a rechargeable batteries

Filed under: Battery, digital camera battery — Tags: , , — ecsem3 @ 5:38 am

Last year I bought a Samsung digital camera (DigimaxA4), and assembly a charger and rechargeable batteries by myself, after a period of time, we found that the battery is not really very durable.In generally I used the camera no more than half an hour on the morning, ,the battery would not have power (previously I used a Sony digital cameras, Sony NP-BG1battery, there is no such situation).

Now every time I normally charge up the battery for more than 10 hours, the battery I bought is 3.7 volts, so at the begning I thought the battery capacity may be too small, and decided to buy a big point of volt-ampere battery, it may be durable . But I saw batteries ,all of them in market ,are nearly 3.7 volts (take the Sony NP-FC11for example ). I do not know is the reason why the battery is not very durable.

Finally I asked a friend, he said the battery he uses is a Samsung original rechargeable batteries, Samsung SLB-0637, it will help to extend battery life, more durable,the most important is the rechargeable batteries are also relatively more cost-effective. The first three times should charge for 12-14 hours. Because it is a memory power’s sake, so the first three should fully activate the battery. Digital cameras themselves are relatively power-hungry digital products, not the Samsung was the case.

In addition ,he tell me how to extend the service life of rechargeable batteries,such as these following colleagues:

  1. To Choice good quality rechargeable batteries (such as brand batteries: Sony battery, Samsung battery and so on).
  2. To select the qualified battery charger(in generally the brand batteries is qualified,for one thing,the  Samsung SBL-1974). A quick charge function should be intact against overcharge kinetic energy, rechargeable batteries should make full use of slow charge.
  3. To reduce the number of battery charge. Each charge should be full of electricity and be all used up.
  4. Capacity of Digital camera battery which is rechargeable ,should be same ,and can not mix old and new together .
  5. To prevent excessive discharge and large current discharge, to prevent short circuit and no electricity storage.

The four wrong common senses of using digital camera battery

Filed under: Battery — Tags: , , — ecsem3 @ 5:35 am

In addition to its quality problem of the Digital camera battery (Before buying brand-name batteries ,such as Samsung SLB-0637, I once experienced), it is also easy to let the battery safety incidents arising for the improper use of the users themselves.Relevant experts suggest that consumers should try to avoid following these for kinds of situations, when using Digital camera battery.

  1. To be Constant power for more than ten hours for the first three times.

    2. Digital camera battery ,themselvese,has the memory function, so the first three time if you charge up the battery for more than ten hours,the battery would fully be activated . in that case,the battery will be more durable than before.

  2. To be Constant power when the camera battery is full.

    3. According to experts, should not use a camera external power supply, when camera battery (taking the Sony NP-BG1 for example,)is full for the characteristics of lithium-ion batteries.there is a misunderstanding that the AC will be directly used in the case of loading the battery charger to use the camera computer for Many users, but in fact they are in the re-charge situation. the AC and battery are used at the same time , In addition to causing decrease in battery life, also resulting in overheating the machine, meanwhile it is easy to damage the other components.

  3. Not to use the battery for a long time .

    4. because the Digital camera battery capacity needs to activate regularly,  so  it is more accurate for the appropriate use of the battery capacity, In addition,it is also wrong not to use the battery for a long time . you should pay attention to the use of the battery re-charging, when using the  battery Every time, and try not to unplug the battery when it has not been charged fully, you should use battery or power adapter separately, and they should not be shared after the battery is full.

  4. Often to assemblly the camera battery by themselves instead of the original rechargeable batteries.

    5. the original rechargeable batterier(for one thing ,the Samsung SBL-1974)
    can help to extend battery life, more durable,the most important is the rechargeable batteries are also relatively more cost-effective.

Finally, do not always remove the battery, and keep the battery position exposed, because it is so easy access to the large amount of dust that caused the battery Poor contact. pay attention to Waterproof moisture-proof shockproof when removing the battery ,and clean the position of the battery on regular with a small brush.
Sowhen you pay more attention to the above four points in their daily, you will find that whether you are using a general or a brand of camera batteries, such as Sony NP-BG1 , your battery life would be much longer than in the past .
