The sources of disused batteries

Filed under: Battery, digital camera battery — Tags: , , , — ecsem3 @ 2:44 am

Batteries are generally divided into disposable batteries and rechargeable Sony NP-BG1 batteries. The main disposable batteries includes zinc-manganese batteries (zinc and manganese dioxide) and zinc mercury batteries (zinc and mercury oxide), etc . The main rechargeable batteries includes cadmium – nickel, iron – nickel. the most we used frequently is zinc-manganese Samsung Battery and zinc-mercury batteries in Our daily life,the main pollution is maily caused by mercury (Hg) and cadmium (Cd) from Samsung SBL-1974 battery .

  1. Mercury toxicity

    2. Mercury, which are commonly called “mercury” is a liquid at room temperature,it can prevent cell cathode zinc oxide, this approach improves the storage life of the Sony Battery.The chemical combination of mercury and mercury have the neurotoxicity ,and also have an adverse effect on endocrine system, immune system,It will trigger people’s slurred speech, unsteady gait, limb paralysis, and lastly lead to generalized convulsions, mental disorders and died.and thae most important is that it is the essential and important element ofSamsung Battery battery,so it worth paying more attention to it for human .

  2. Cadmium Toxicity

    3. Cadmium is not a trace element necessary for the human body, and there is no cadmium in the body of newborn babies, , but it increases with age, and gradually accumulated. renal toxicity fiom Cadmium can cause kidney damage ,which is irreversible.but there are some Cadmium inSamsung Battery.

  3. Manganese toxicity

    4. Excessive(which is inSony NP-FC11battery) levels of manganese accumulation in the body can cause neurological dysfunction, it Showed early an integrated sexual dysfunction, the emergence of heavier speech monotonous, dull expression, emotional indifference, accompanied by psychological symptoms.The emergence of heavier is the speech monotonous, dull expression,and emotional indifference, and accompanied by psychological symptoms.

  4. Lead toxicity

    5. it also is the important element of the Samsung SLB-0637battery,so excessive Lead is harmful to human heath ,and Lead play a major role in the nervous system,hematopoietic system, digestive system, and liver, kidney and other organs,it Can inhibit the metabolism of hemoglobin synthesis,and also be able to directly act on the mature red blood cells,it have a more impact on infants and young children.It will lead to children’s physical growth retardation,and the chronic lead fromSony NP-FC11will lead children’s mental retardation.

  5. Nickel toxicity

    6. Nickel powder from Sony NP-BG1battery dissolved in the blood, and participate in the body circulation,beacause of the strong toxicity, it can damage the central nervous system, and cause abnormal blood vessels, thae severe cases lead to cancer.

  6. Zinc toxicity

    7. Zinc is an essential element of the human body(but meanwhile it also is the essential element of the Digital Camera Battery), less toxic,oral zinc sulphate 1000mg only make people acute poisoning,However, inhalation of zinc oxide dust can cause poisoning.Its symptoms are generalized fatigue, muscle pain, difficulty breathing, vomiting, diarrhea, severe heart weakness, prostration, died after convulsions .

Some ways to extend battery life

Filed under: battery grip, digital camera battery — Tags: , , , — ecsem3 @ 12:14 am

People have a great importance to improve the capacity of lithium-ion batteries ,and want to achieve maximum working hours by buying the physical size of the smallest battery products . However, in some applications,it is more important for longer battery life, charge times or more safer than the battery, Sony NP-BG1,capacity of the battery . Here are a few methods to extend the battery life.

there does not exist to extend or shorten theDigital Camera Battery life of any single factor, but often several factors which have combined to play a role. in terms of the extension of life cyclethe,there aire some following ways to extend battery life:

  1. to take the practice of using part of the discharge. it will greatly extend the cycle of life by using 20% or 30% of battery,Samsung Battery capacity before recharging up the battery . As a general rule,it is equal to for 5 to 10 shallow discharge cycles and a full discharge cycles. Even though some may reach thousands of discharge cycles, but it also can shorten battery life to keep the battery,Samsung SBL-1974,at full charge state. If possible, should avoid over-discharge cycles (down to 2.5 V or 3V, depending on chemicalmaterials).
  2. To avoid charging to 100% of capacity. it can do this to choose a lower float voltage . Reducing the float voltage will increase the cycle of life and service life, the cost is to reduce the battery , Samsung SBL-1974,capacity. Float ing ivoltage of 100mV to 300mV can reduce the cycle of life is prolonged from 2 to 5 times or more. Compared with other chemical materials, lithium-ion cobalt chemical materials are more sensitive to higher float voltage. the floating voltage of Lithium-ion batteries are lower than generally lithium-ion battery.
  3. Selection of suitable methods for charge termination. Choose one with the minimum charge current termination (C/10 or C / x) of the charger, you can also extend battery(for one thing,the Samsung SBL-1974) life by not charging to 100% of capacity,. For example, the effect is similar to reduce to C / 5 and ended at the float charge cycle and reduce float voltage down to 4.1V, In the both cases, the battery(such asSony NP-FC11) be charged to about 85% of capacity, which is an important factor in battery life.
  4. To Limit battery temperature. Restrictions on the limits of the battery (take the Samsung SLB-0637 for example )temperature can extend battery life, particularly the prohibition of charging below 0 ℃.
  5. To avoid a large charge and dischargeSony Batterycurrent , because it will shorten the cycle of life. Some chemical materials are more suitable for large currents, such as lithium-ion manganese and phosphate lithium-ion battery. Large current can impose too much pressure on the battery.
  6. Avoid 2V or 2.5V below the depth of discharge, because it would permanently damage the rapid lithium-ion ,Sony NP-FC11 batteries. the metal -plating deposition may occur , which would cause a short circuit so that the battery is not available or unsafe.

How to distinguish battery?

Filed under: digital camera battery — Tags: , , — ecsem3 @ 8:45 pm

In general there are three kinds of batteries for us to  use: 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? In general 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. Another distinction 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 scrapped after two years, while Ni-MH Digital Camera Battery can charge much more than 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.
  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-BG1 battery I useed is produced in Japanese.

Battery is made from the batteries, generally people are talking about 4Cell, 6Cell,it means 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 Samsung SLB-0637 from China ).China,Samsung ,and Taiwan Province of China  are mostly based on  in processing ,and the core of battery is produced in Japan . In the next-generation cell batteries, some already do not use such a garden-shaped batteries, but do  a lithium polymer block to get greater power and smaller size.

Now that the price of the original equipment batteries is very expensive in market, it is around 1000-1500 in general, so for extending battery life,some of my friends started to replace the battery with Batteries batteries. it is possible in Theory , but in fact it is not .the reason is as follow :

  1. Due to reasons in process, the batteries are generally used the ultrasonic welding, there is no gap,and  it is difficult to apart, even if the hardware is also very difficult to disassemble a close, and some camcorder batteries ,such as Sony NP-FC11 .
  2. because of the internal protection circuit in battery, the event of the internal temperature is too high,it  will automatically cut off to protective battery, the piece of the circuit are damaged when replacing the battery,consequences would be unthinkable.

So I still do not recommend to replace batteriesby yourself, 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

Filed under: digital camera battery — Tags: , , — ecsem3 @ 8:43 pm

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.

  2. To identify the authenticity by observing the printing quality.

    3. 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.

  3. 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 Samsung logo.Some fake batteries do not. If the deformation of the above logo, fonts, error or ambiguity, must be a fake no doubt.
  4. To observe the quality of the battery packaging

    5. 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.

The classification of the laptop battery

Filed under: Battery, battery grip — Tags: , , — ecsem3 @ 8:40 pm

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

  1. because of their too early age ,there are many headache shortcomings for Nickel Cadmium  Sony NP-FC11 NI-CD , such as: bulky, heavy weight, capacity, small, short life, there is memory effect, etc. (useless), and now no longer in use .
  2. Ni-MH battery is more environmentally friendly some compared to other Samsung,it is also by far the most environmentally friendly battery in the world.
  3. Li-ion Samsung SBL-1974could offer important advantages, including a small size, light weight, large capacity, low memory effect, charging time is short, etc.,but you will often see the back of the battery properly abandoned and handling lithium batteries instructions? It will cause environmental pollution. to discard the lithium Samsung SLB-0637

Now some people may be misunderstanding of lithium Sony NP-FC11 , they believe lithium batteries can not remember things, in fact , only  relatively small memory, it seems not to be very clear. And lithium batteries can be divided into lithium and lithium-ion battery two kinds. Lithium-Ion Digital Camera Battery has been in world for a long time ,but it is not safe when used and often might burn, burst when is  in charge, perhaps because of the sake of lithium element too active. Then there is an improved lithium-ion batteries,the element of active ingredients is added in lithium so that lithium is really safe .efficient and convenient, while the older Lithium-Ion Sony Batteryalso is eliminated.
