Dell and Apple Computer announced massive recalls of laptop computer batteries in the summertime of 2006, followed by Toshiba and Lenovo. Under the right circumstances, these batteries could overheat, potentially causing burns, an explosion or a fire.
To understand why that happened, it is helpful to know a little bit about how batteries work.
Batteries have a negatively charged terminal and a positively charged terminal. In a battery, energy from electrochemical reactions causes electrons (negatively charged particles) to collect at the laptop battery dell negatively charged pole. Charged particles are drawn to opposite charge, so in the event you connect a battery to a circuit, the electrons will flow from the negative pole, through the circuit and to the battery positively charged pole. In other words, the battery generates a moving charge, or electricity.
The exact reaction that generates the electrons varies, depending on the type of battery. In a lithium-ion battery, you will find pressurized containers that house a coil of metal and a flammable, lithium-containing liquid. The manufacturing method creates tiny pieces of metal that float in the liquid. Manufacturers can not prevent these metal fragments, but nice manufacturing techniques limit their size and number.
The cells of a lithium-ion battery also contain separators that keep the anodes and cathodes, or positive and negative poles, from touching each other.

In case of problems HP laptop, some of the a lot of accustomed are accompanying to the battery, as credible in abounding forums belletrist on the Internet. (HP Pavilion dv2000 battery)
Here are a brace of HP notebooks that problems associated with all-overs and some annual on how to breach them:
One of the a lot of accustomed problems awning the HP laptop arrangement to charge, otherwise, if it is plugged. Even if the arrangement indicator laptop battery dell is at 0% and is acutely in allegation of the bulk can not admission this number. Another accustomed affirmation is to unplug the AC Adapter HP Pavilion DV6000 that does not changeabout off the laptop, although admonishing that the arrangement is consistently 0% with a calendar that it should be in. This is absolutely worrying, because even the new laptops are bogus are accustomed to affectation such problems HP laptop.
The ancient action to do if confronted with this problem, the arrangement and the Re-seat removed. In some cases, these types of problems HP laptop, abolishment worse than a contact, and this should be adequate to breach the problem.
In added cases, such problems HP laptop the aftereffect of a burst arrangement acquired by agonize or overheating. For these problems, you may be able to accompany the arrangement action if he provided a displace button, as in the case of abounding beat HP Pavilion ZV5000 album batteries.
Some of the HP laptop alarming problems to do with absolute batteries that acquire been articular as bonfire hazards. Up to 70,000 HP batteries acquire been recalled, so if your laptop uses one of them, the best action to do to stop and get in draft with them with a HP representative.

Will a higher capacity (mAh) battery ruin my laptop?
Rechargeable batteries have a lower capacity than disposable alkaline.
It is quite common that some people think that a single use battery lasts longer than a rechargeable battery. The logical error here is "give and take" alkaline battery provides a charge long, while the rechargeable battery offers many short positions. This is false. Rechargeable batteries are made using the chemistry of nickel-metal hydride is greater than the alkaline manganese http://dell6000.blog.com/ zinc and use of chemicals oxide. A charge cycle of a rechargeable battery will last 3-4 times longer than a charging cycle of disposable alkaline battery. The real "give and take" here is that the rechargeable batteries cost much more than disposable alkaline, well, you need a charger too.
Verdict: False
Misleading battery terms: Batteries Super last duty instead of a battery of non-super destination.
Do you recognize any of the following steps in the packaging of the batteries? high strength, high strength Super, Ultra capacity, rapid charger, long life, the maximum load, etc.
Since there is no industry standard capacity of a battery from now, many companies use these words to market their batteries. The correct way to find the power of a rating to see the chemistry of the battery and made. To clarify things, a "Super Mega Heavy Duty" alkaline battery would have no chance against a standard lithium battery.
Verdict: False
Put the batteries in the freezer prolongs its life.
Keep Alkaline batteries stored at room temperature, "only gives them a self-discharge rate of 2% per year. Since the type of car is so low, it is not really worth going through the hassle of putting them in the freezer and take space that could be used for ice cream. Although the myth is technically true, it is likely that you put the batteries for use in less than a year.
But, if the batteries are stored at higher temperatures around 85 degrees Fahrenheit, the actual discharge rises to 5% and the increase of 100 degrees at 25%. So basically, do not worry about the batteries lose their charge unless the weather is very hot.
Verdict: (technically) True
It is best to recharge batteries slowly.
There are some people who believe that chargers overnight are best for rapid battery chargers because the slow transfer of energy does not diminish its capacity. In fact, there fastloaders adversely affect battery capacity worse than other chargers out there. The real cause of the loss of capacity is overloaded. When a battery continues to charge after reaching maximum voltage, the capacity will slowly decrease. Make sure the charger is a "smart" charger automatically shuts off when the batteries are fully charged.
Verdict: False
You must use a rechargeable battery until you are dead.
This is true for Ni-Cad and Ni-MH batteries. If not fully used their energy and the defendants will begin to develop a "memory." Decreases the total memory capacity of a battery. The more memory the more it loses develops a battery capacity. This is not true for lithium ion cells however. the lithium ion cells are not affected by the memory effect and can be recharged at any time.
Verdict: True to Ni-Cad and Ni-MH, Li-Ion False.
Storing a lead acid battery on the cement floor slowly download.
The storage, charging batteries or operate in the concrete is perfectly fine. The most important things to avoid:
1.Freezing. Avoid places where it is expected that the freezing temperature. Keep the battery in a high state of charge also prevent freezing. Freezing results in irreparable damage to battery plates and containers. [The freeze may occur between -19 degrees Fahrenheit (40% load) and -98 degrees (fully charged)]
2.Heat. Avoid direct exposure to heat sources such as radiators or heaters. Temperatures above 80 degrees accelerate the characteristics of the battery self-discharge.
3.Step storage step of the procedure: 1. Fully charge the battery before storing. 2. Store in a cool, dry place, laptop battery dell protected from the weather. 3. During storage, monitor the specific gravity (flooded) or voltage. Storage batteries should be given a quick charge when they show a rate of 70% or less. Fully charge the battery before restarting.
The best place to keep an SLA battery is in a cool environment with a battery supply. offers from the battery to keep the battery at a voltage of proper storage so that it retains the capacity. Some of them also improve their performance.
Verdict: False
Increased capacity (mAh) battery ruin my laptop?
Increased capacity (mAh) will not ruin your laptop. Extended batteries are those that have more capacity (mAh), or amps, to improve the device for an extended period of time. If your laptop has been driven by a lower capacity (mAh) battery, switching to a long lasting battery with more capacity (mAh) will not damage your laptop. The devices can only be affected if the stresses do not coincide.

Battery manufacturers cost savings over
HP laptop similar problems have also arisen. For the network, statistics show that nearly two weeks, the complaint against Hewlett-Packard has reached hundreds of laptops overheating.
The network of 315 consumer complaints in July and August in the computer industry with the complaints lodged complaints HP laptop overheating have focused more in recent months one of the topics.
In this sense, the experts remind consumers should seek to safeguard their legitimate rights and interests, using these potential safety hazards of portable devices, users must take the initiative to log on to its official website or customer service center calls on the processes involved in memory, manufacturers of machine maintenance.
Fever is widespread
News HP Guo Zhenyu, head of public relations interviews means that the warming is due to these two series of notebooks used by faulty NVIDIA graphics cards, notebook itself is not a design flaw. As consumers of the application for recall, HP has so far not been a corresponding plan.
With the laptop in the world and the popularity of the domestic market in recent years, an increasing number of memory cards, and many of them are related to the Chinese market. Among them, laptop battery dell the number of complaints, the main reason is the battery and body heat.
Last year in September, Sony, due to its links with parts of laptop batteries and there is no risk of short circuit and overheating can cause security problems, problems in the overall recovery of nearly 44 million computers, of which August 7 million units in the Chinese market. Last year in October, Sony, Dell, Toshiba, HP announced the recall of 100,000 in the joint operation of the problems with Sony laptop battery were about 30 models of aircraft. notebook batteries due to occur in the course of overheating, some of them will appear the phenomenon of smoke and fire.
Remember similar events in the past two years after another, including the sellers of the world's largest PC brand, the types and quantities and also a lot. In addition, Apple and other notebook batteries overheating due to an explosion of video, occasionally appeared on the Internet.
More cost sources of the problem
With the industry analysis, resulting in recent years due to overheating problems caused by mobile security, often with some companies, the cost of excessive compression.
Moreover, while the Intel Atom processor and platform CULV are low power and low temperature, so thin and light notebook can achieve a small size, but also economic, for quality products and mobile home prices non-conventional points of thermal efficiency.
Reporter learned that most users now use their laptop battery dissatisfaction that many of the problems when the battery is the first part. They also said that although prices are a series of laptop power cord cheap laptops, but the material of the shell is not so good before, and situations of the position palm rest hot prone.
Notebook batteries and heating is more PC makers headaches. Until now, most laptops, hardware and internal battery, the heating line has been criticized by users.
PC makers have admitted in recent years, intense market competition, notebook, notebook margins have deteriorated to the market, the products not only to keep pace, prices should also have benefits which means that the cost of having some control.
