how lithium battery maintenance is correct

Tue, 15 Dec 2009 01:52:52 -0500

We love machine exactly how lithium battery maintenance is correct? This problem has plagued many people for a long time at the forum there is no uniform opinion. I looked up some information and consulted a friend (who the Department of electrochemical professional doctorate), and the introduction of the Friends under the advice of a well-known domestic battery, deputy director of the Institute. Can not arrogantly have resolved the issue and maintenance of lithium ion, but some of his recently acquired knowledge and experience to write about. The author of the study beyond the high school chemistry chemical Coban Orsay, have since been studying and working in the IT field, 隔行如隔山, one must understand that even more shallow, N. of salt, but expert Dell inspiron 9400 battery Compaq presario R3000 battery Dell inspiron 1300 Battery.

Lithium-ion battery cathode material of lithium active compounds are usually composed of negative electrode is a special molecular structure of carbon. The common major components of LiCoO2 cathode materials
Charging
Positive reaction: LiCoO2 Li1-xCoO2 + xLi + + xe -
Negative reaction: C + xLi + + xe-CLix
Battery overall reaction: LiCoO2 + C Li1-xCoO2 + CLix
Discharge, then the occurrence of the above reaction of the reverse reaction.

Charging, the battery added to the positive pole of the electric potential to force the release of compounds Li + ions, embedded negative elements arranged in lamellar structure of the carbon. Discharge, Li + ion from the lamellar structure of carbon in the escape and re-cathode combination of compounds. Li + movement to promote a current.

Laptop toshiba PA3399U-2BRS battery maintenance methods - 3, after the exhaustion of electricity charge and avoid charging time is too long regardless of your notebook to use nickel-metal hydride or lithium-electric power, it must take charge after the exhaustion of power (capacity less than 1%), which is The best way to avoid the memory effect. There is no memory effect on lithium to say, I have been in the preceding description is misleading and irresponsible businesses. Lithium-Ion battery memory effect will be the same, but it is the memory effect than nickel-metal hydride smaller Bale. Mobile phone battery charging with the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the battery contacts with metal objects such as attention, not much to mention here also.

【1】 errors reach 100% charge will be an explosion

As the operational need, urban areas, Mr. Lin has recently tried to buy a laptop computer. However, when he was buying was heard people say that when the laptop is usually in charge can only charge to 99%, can not charge to 100%, if the charge to 100%, then the laptop battery will explode. After hearing this, Mr. Lin hesitated, and in the end this laptop battery Security less secure?

Industry sources have told reporters on the market of this popular "saying" just a rumor. Because the laptop battery will appear in terms of risk of explosion is very small, only send a maximum of heat caused by melting shell and rarely cause an explosion. The few published laptop battery explosion, mostly due to the battery when in the production of quality problems caused. The reason why laptop battery can not charge to 99% after the then 100%, it is because the battery control circuit of the record and the state of the battery itself has gone wrong, the battery has not reached the voltage control circuit in the record, so control circuit has been In the power-up, charging, but in fact the battery is already full, and encountered this problem can be corrected to resolve.

And you need to recharge Dell Latitude D800 battery

Thu, 26 Nov 2009 02:25:51 -0500

And you need to recharge Dell Latitude D800 battery in order to cope with the anticipated upcoming busy communications will lead to an important event, even though there are a lot of battery power over time, then you just charge ahead, because you are not really lost, "a" sub-charge cycle life , that is, "0.x" times only, and often this x will be very small.
Run out of battery power and then filling the remainder of the principle is not want you to go to the extreme. And long, like charging a widespread view that "as far as possible the cell phone battery power runs out, it is best to use automatic shutdown." This is really just practice on nickel batteries, The purpose is to avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, still do not charge to continue to use the example has been used in automatic shutdown. The results in this case, cell phone charging and starting later in the no response, had to give customer service overhaul. In fact, this is because of the battery caused by excessive electrical discharges in low voltage, so that does not have the normal charge and the boot and conditions.

Laptop battery maintenance methods - 2, to minimize the use of this method gives the number of batteries I feel like some petty, but it is also the most effective. We should know that the battery charge and discharge frequency is directly related to life on one charge, the battery on a step forward to retirement. Suggest that you try to use an external power supply, use an external power supply when the battery removed. Some friends convenience, often several times a day Plug Power, and notebook computers equipped with a battery, to do so, even greater damage to the battery. Because each access to external power supply is equivalent to the battery charge time, battery life shortened by a naturally. Dell Inspiron E1405 battery HP PB994A battery Dell Latitude C600 battery

Toshiba Laptop Battery a long time do not use,

Thu, 12 Nov 2009 21:45:16 -0500

In other words, even if your Toshiba Laptop Battery a long time do not use, nor capable stood, preferably a period of time to conduct a charge and discharge, in order to maintain the Toshiba laptop battery "state." However, because Toshiba notebook Lithium-Ion battery itself has some memory effect (generally say that Lithium-Ion battery without memory effect is wrong, lithium power companies actually have memory effect, only a very small only), preferably within the first Toshiba laptop battery power runs out, and then for charging, such an effect would be better. Of course, the best control the charging time of 12 hours, or excessive charging will lead to a reduction of Toshiba notebook battery life.

So after a long period after use, how to judge their own Toshiba laptop battery is also a normal job? In fact, it is not hard, said Toshiba laptop batteries in general will increase with the frequency of use, gradual reduction in working time is short, once the Toshiba laptop battery life up to less than half the nominal use of time, or use a long time to instability when the short time you have to be vigilant, because your Toshiba laptop battery may have come to the end of life, the best preparation ahead of a danger.

Now that ride in the Ni-MH battery models have been difficult to see, so in this section I will focus on lithium-ion batteries are widely applied.
General lithium-ion battery life-cycle of 300 to 500 charge-discharge. But this does not mean you rarely use the battery it can be life extension.
Original Batteries as a physical work environment factors susceptible to influence, but the main reason leading to cell loss is caused by oxidation of the battery internal resistance increase,
This is why many users will complain that they are fully charged battery in use why suddenly has no power. It may therefore be understood that this problem,
That is when the end of the battery off the assembly line, it's internal life, the clock will then start walking, even if the battery you will be left unused, a
Can only be to a certain extent, the loss rate of only delay the battery. But then again, and always resting the side of the battery, then the meaning of mobile notebook computers idle talk?
