Laptop Battery ,how much do you know

The birth of the day from the laptop, the battery of this “servant” had been accompanied on its side, there is no battery, it can be said can not be called the laptop “mobile computer.” With the notebook performance and technology continues to improve with the improvement, it is the “servant” of the “quality” is also getting higher and higher, from the past, nickel-chromium batteries, nickel-metal hydride batteries to now have been using lithium batteries may be popular even after the fuel the battery, few people care about this and notebooks are closely related to what – the battery, then let me work with you to look into the laptop battery.

The classification and distinction between the battery In general we use there are three kinds of batteries, 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI, in recent years, In the notebook field has also been a fuel cell, its only by-product of water and heat, no noise, the basic pollution-free, efficient power generation systems in general higher than the multi-reach 43 ~ 58%, if the heat produced by the reaction utilization, efficiency can be up to 80%! Is a clean and environmentally friendly power. Because of Dell GK479 its technology was not perfect, there are still many problems to be solved, and now it is in terms of cost, size, weight, ease of access to fuel, both absolutely can not and traditional lithium batteries and polymer lithium battery to compete.

NI-CD Ni-Cd batteries because of their age is too early, so have many of the shortcomings of a headache, such as: bulky, heavy weight, capacity, small, short life, there is memory effect, etc. (useless), and now no longer in use. Now mainly NI-MH battery Ni-MH and LI lithium two kinds. Ni-MH battery which is also active in the battery industry, 1:00, compared to other batteries, nickel-metal hydride batteries to be more environmentally friendly some, it is also by far the most environmentally friendly battery,like Dell xps m1730 battery while the lithium battery Well, with a small size, light weight, large capacity, low memory effect, charging time is short, etc., well received by customers love, but you will often see the back of the battery properly abandoned and handling lithium batteries instructions? Because the lithium batteries to discard will cause environmental pollution.

 

Now, some people may be misunderstanding of lithium batteries, lithium batteries do not remember that, in fact, lithium is not without memory, but only relatively small memory, it seems not very clear. And lithium batteries can be divided into lithium and lithium-ion battery two kinds. Lithium-Ion battery will have a long time ago, and it is not safe when used often in charge when burning, bursting, perhaps because of the sake of lithium element too active. Then there is an improved lithium-ion batteries, lithium can inhibit the added element of active ingredients, so that lithium really a safe, efficient, convenient, while the older Lithium-Ion battery also will be eliminated.more like Vaio VGN-SZ battery As to how to distinguish them from the battery’s label will be able to identify, lithium battery for LI, lithium-ion battery LI-ION.

 

Now that the market price of the original equipment batteries are very expensive, generally place around 1000-1500, so some of my friends started to replace the battery, through their own batteries to achieve the purpose of extending battery life. Theory should, it is possible, but due process reasons, the Presario V3000 battery batteries are generally used ultrasonic welding, there is no gap, it is difficult apart, even if the hardware is also very difficult to disassemble a close, I see the electronic Shangyuan to the two hands are their own battery replacement batteries and then sell finished, the battery can be a combination of Office, it is clear to see there are 502 marks, after gluing, even with batteries, replace more time to find a match difficult.

How to prevent battery explosion

Any part of the laptop battery within the instantaneous discharge of solid material, was pushed away from the battery to more than 25cm distance, called the explosion. Determine whether or not the battery explosion, using the following experimental conditions: a network of experimental hooded batteries, battery living in the middle, away from the net either side of cover for 25cm. Net density of 6-7 root / cm, a diameter of cable used 0.25mm soft aluminum, if the non-solid part of the experiment through the network mask to prove that the battery did not explode.

Battery explosion is generally

  • 1. safety valve design is unreasonable, will not achieve any security role.
  • 2. when the battery charge is too high internal pressure.
  • 3. the laptop battery has problems, such as: N / P ratio unreasonable; you will not hear a battery will explode, they have a fear of the battery. In fact, as long as you use the products (including batteries and chargers) is a qualified product, there would not have this problem.
  • Qualified products have been manufactured prior to the rigorous testing, and with batteries and chargers are red discharge protection device, so even if the battery or charger in which a loss of protection, another can also protect your battery will not have been sufficient, there will be no charge for the phenomenon of the explosion. even if the batteries and chargers are failure of the protection device, if you notice that the battery(dell gd761 , sony vgp-bps2c , vgp bps5a ) is hot, stop charging immediately and sent to professional inspection will prevent the occurrence of this phenomenon.

    Users to discuss on the battery explosion finishing: a statement

  • 1. the closure may be your very good, intense chemical reaction. There is no safe gas out, it may be fried.
  • 2. deburring and micro-short circuit caused by dust.
  • 3. the problem is the charger you?
  • 4. is not equipped with anti-overcurrent (short circuit) ptc used it.
  • 5. the battery should be no control of the production process, and lead to expansion of charging and cause a short circuit chip.
  • 6. may be bad batteries and charger, the charger lead to charge-off place which protect the sample (data) abnormal. Personal guess, bad is the cause of the explosion led to
  • 7. the ambient temperature to be considered, is likely to charge when the lenovo battery temperature, especially the kind of place in India, between the batteries and chargers poor thermal heating battery charger or the battery if the internal There are flaws in the internal short circuit is likely to lead to the gradual evolution of the explosion as the fire, if not the charger, the high temperature may also lead to over charge protection failure (provided that the internal battery overcharge protection circuit failure of protection).
  • 8. may be to protect the plate voltage up to a problem.
  • Another way of saying:

  • 1. in fact, the battery explosion, no analysis of several companies to come out, the majority of factory batteries are nonsense, to find themselves and their customers to comply with reasons to accept others.
  • 2. can not find a better reason, I remember that when you write the report insisted the explosion was an accident.
  • 3. if an explosion in here can clear the issue, I am afraid no one can do the battery. Lithium is now what is the biggest flaw?Good lithium iom battery, dell inspiron 6400 battery , powerbook G4 battery , inspiron e1705 battery , thinkpad t60 battery .
  • 4. the capacity of lithium batteries or not too much to prevent the explosion of offensive weapons into!
