The reason of the battery explosion

by: rain0123   Keywords: camera, battery, Kodak, KLIC, 7004

In recent years, as people's living standards improve, the using battery,Sony NP-FH100 frequency lis ever-increasing , they often are inseparable from the battery ,such as digital cameras which people are familiar with , laptops and other electronic products . However, the frequency of accidents is also rising ,which caused by the battery ,from the iPhone, Nokia's mobile phone to the cottage, the battery explosion are not uncommon(recently we have not heared such words about the Panasonic CGR-S003battery explosion) even in our lives will be commonly used in cell No. 5 explosion.

Recently, the exploding battery phenomena reported in network ,I briefly summarized the reason of battery explosion.

  1. there are two reason of the battery explosion, one is a "non-normal use," such as the Kodak KLIC-7004 battery is shorted, the battery used by the current is too large, non-rechargeable batteries Naqu charge, the temperature of using battery is high , or it is negative anti-loaded when use the battery.
  2. Another reason is that "there is no reason blew." Mainly it occurred in fake brand-name batterie,such as Sony NP-FH100 battrey . Such an explosion is not because there are inflammable and explosive substances in the battery,but because of inferior material and impurities is within the battery, and also lacking substance, leading to the production of gas inside the battery,Canon NB-4L, the internal pressure increase, so it is easy to "blew."
  3. In addition, improper use of the charger can easily cause explosion for rechargeable batteries,take Kodak KLIC-7001 battery for example. Article via:batterytalk laptopinfo

The experience of buying a rechargeable batteries

by: rain0123   Keywords: battery

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 use techniques of digital camera and camcorder rechargeable batteries

by: rain0123   Keywords: camera

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, .

how we can know batteries from others?

by: rain0123   Keywords: battery

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 identification method of the battery

While digital products bring lots of joy to people's lives,for one thing , Samsung battery,but you do not take it lightly ,when purchasing digital products and accessories to consumers, it is necessary to learn some tips for identifying true and false . Today we set about to strip the last layer of JS skin and thoroughly expose the fake lithium batteries!

  1. To distinguish true and false by the anti-counterfeiting marks.
  2. the security signs is used to post In outer package(such as the Sony battery with a Sony security signs in the outer package), this is also one clear distinction place between genuine and fake batteries. the battery generally have a very strong three-dimensional sense of security signs, just like we are now using identity surfaces, while the fake battery have no three-dimensional feeling, fonts rather ambiguous, and some even ordered Sanji missing in general.

  3. To identify the authenticity by observing the printing quality.
  4. In addition to observing the logo addition, you can identify the authenticity through print quality of the cell surface. True font size print of the battery is equal, and can be clearly read,but the printing font of the false battery will suddenly become smaller and obscure. The following point is to the the place of qualified label,take for instance the Sony battery, really Sony NP-BG1,their qualified label are in the battery below,the fake batteries qualified label appeared in the top of the battery.

  5. For distinguishing true and false to observe the logo.

    Before you buy battery,you can look at the manufacturers logo on the surface of the battery, including logo and product models mark the words,take the Sony NP-FC11 for example ,the SONY and "infoLITHIUM; The original equipment batteries surface of the logo is clear and accurate, such as Samsung battery,the battery on the back black with white characters Panasonic logo? Some fake batteries do not. If the deformation of the above logo, fonts, error or ambiguity, must be a fake no doubt.

  6. To observe the quality of the battery packaging
  7. The outer surface of really battery is smooth, the false bottom edge of the battery packaging is rough, not smooth; real battery with the battery-shaped plastic undulating and angular shell, fake batteries do not have the plastic shell edges and corners,let us say Samsung SBL-1974.

Finally, to remind consumers to buy Battery signs of the times necessary to keep their eyes open,such as these famous battery,Sony battery,Samsung battery,Samsung batteryand so on, so as to avoid causing unnecessary economic losses.
