First of all, got a new battery,   many users approach is in accordance with business tips in lithium batteries used in the previous three or more of charge 12 hours.

In this connection, there are also many online debates, but I found that in actual use, in fact, that for the majority of laptop batteries is not necessary. Why? Businessmen say this was done in order to fully activate the activity of the battery is completely wake-up a new battery. For this reason it sounds very full and credible, but we have not thought about this problem.

If, laptop battery completely wake-up a new battery. For this reason it sounds very full and credible, but we have not thought about this problem.

If, laptop battery manufacturer has not yet been fully activated on the appearance, then this can be said that only a semi-finished products. Can not require each user to activate cells to master the skills, in reality impossible.

Thus, in the battery factory has been in full activation of the vendor. How are users 12-hour rechargeable battery is conducive to use? In this I give a negative answer, the current laptop battery has improved power management circuitry and charging management system, when the battery reached saturation, the control circuit automatically switch to short-circuit state, so a later time is merely a waste of time only.

How can I do to activate the activity of the battery? In fact, the vendor for the activation of the battery case in the absence of overload will be a long time the battery charge and discharge. Therefore, the first three charge 12 hours is unnecessary.

Again, many users use the battery very confused, what should or should not be charged until the battery is fully depleted. In fact, answering this question should be like this, if you can do that is certainly a good thing, but only if you have too much trouble. Of course, I mean talking about here is absolutely not over-

discharge, over-discharge is absolutely proven harmful to the battery, it will shorten the battery life. Thus, when a low power consumption when the notebook

prompts can be a timely charge. Some merchants have repeatedly declared their lithium batteries no memory effect, this practice is extremely irresponsible.

So when you have more power when the battery is not charging for the good, because the memory effect does exist.

Third, for a long time without the battery should be how to do, it is recommended into the 40-50% of the electricity, placed in the cold shade, the following parameters illustrate the problem.        Of course, the best to take the battery out every month to use them once, both to ensure the battery a good state of preservation, but also alienating the loss of damage to the battery power completely.

Three dispute of the Notebook battery

Notebook batteries due to the high cost of belonging to the "consumables" that there is a lot of controversy over the use of.

With the gradual popularity of notebook computers, notebook computers on all the attendant problems, in a variety of media, the most controversial number of notebook batteries to the proper use of methods, some article said that the use of personal experiences notebook batteries, while others claimed expert guidance, all kinds of stories are, many argue.

The author is an ordinary notebook users, although not experts, but has many years experience in the use of the notebook, I found through friends dozens of university students using a laptop, so that they talk about their notebook battery life experiences, coupled with their own experience that summed up what we as a reference to the hope that can give us some help.

Argument 1:

Activation of a new Dell Ispiron 6400 battery

1 views: we buy a new battery in, there will be more than 3 percent of electricity, the battery's remaining power is used up, until the shutdown, and then use an external power supply charge. Charging time must be more than 12 hours, repeated three times to do in order to activate the battery.

2 views: no need for batteries for 10 hours to activate the battery charge activity, in accordance with the normal charge-discharge-activated manner.

Findings: The author, after investigation, 24 college notebook users, the 18 is the second point of view, but this approach did not charge the battery for future use can hurt, of course, to exclude damage to natural factors. I own the same way, the new normal use the battery when a maximum of two and a half hours, the current over the past two years, the state of the battery is still good, still able to achieve more than two hours, so I have been satisfied.

Proposed method: I agree with the second point of view, according to available data indicate that activation of the battery should be completed in the factory, the notebook battery factory with a little electricity is the natural wear and tear in order to avoid damage to the battery. Should be activated battery protection circuit in the absence of circumstances, the circuit itself can be a lithium battery protection circuit, this circuit is designed in order to avoid over-charging and discharging batteries, general battery after full charge when the indicator goes out , non-rechargeable batteries into the power on, then you plug then plug the battery in the face of what to charge for?

The situation from the battery on the battery will be able to see there is no charge, and teach you a simple way to determine the battery can be there in charge when the battery will heat the phenomenon, when an hour after the battery is full of (power do not pull the plug), you try the battery again to see if the battery does not heat hot?

The results must be cold, because the state of battery charge and discharge is not of course, do not heat. Notebook manufacturers at the factory will be proposed that a new battery for more than 10 hours. This may allow some users have had the wrong point of view first, the author of this opinion is that notebook makers should take into account some new users to use a new battery when the charge does not fully grasp the skills, simply so that they charge 10 hours, so this should be the business of expediency.

Argument 2:

Unplug the external power supply when the battery?

1 views: the use of external power supply when the battery removed.

Perspective 2: the use of an external battery power when not removed.

Survey: Most students in the use of external power supply when the battery removed, only a small number of the use of external power supply when the battery is on top, which a small number of students are used in a number of international brand-name brand.

Proposed method: In fact, the battery is removed, the conflicts focused on the use of external power supply when the battery is charging up the issue. We should know that the number of battery charge and discharge is directly related to the life of lithium batteries in general set the number of charging and discharging are fixed number of charge cycles only 400-600 times, specially to improve the product but also 800 per charge on a battery a step forward to retirement. The first perspective is nothing more than fear of the use of power, the battery will be recharged on the top, not only increase the number of charge cycles and will have sufficient cause.

The second view is that the battery is full power on the computer, in the use of external power supplies will not recharge. In fact, both views have their right side, but also the wrong place. Because it is only the views expressed by individual people, not very comprehensive, after my investigation, many notebook manufacturers have to take into account the vulnerability of the battery and the product is added to the protection of the battery technology, and therefore the corresponding different brand notebook batteries charge of different protection technologies such as some large companies in this area is pretty good, such as: IBM, HP, Toshiba, Compaq, etc.. Which is considered the most thoughtful of IBM, IBM laptop battery discharge can detect the situation, ThinkPad notebook battery power only when less than 95% will be automatically recharged.

This can play a very good protective effect of the battery, and now have quite a number of other manufacturers to follow. Therefore, the battery like this, you do not need to use when drawing down, because only when the power is lower than 95% of the time it will charge. Nevertheless, such a long time if you are using your computer, or the battery removed for better long-running notebook because of the heat generated would cause some harm to the battery. However, some other "little brand" notebook batteries, may not enjoy such treatment because it has not done inside the battery protection technology.

I like to use a certain brand of notebook computers, if the battery is full on top, in the use of external power supply must certainly recharged, because the battery will have a loss when stored, it is impossible to achieve 100%, and if not 100% , power supply connected to the charge. Each access to external power supply to the battery charge is equivalent to one, although only a small charge will be the time. It is proposed that all the time in the use of machinery in accordance with their own circumstances, notebook manual check, choose whether to use an external power supply the Dell INSPIRON 6000 Notebook Battery removed.

Argument 3:

How to charge?

Point of view 1: battery power should always be all used up, so that consumption of notebook computer to shutdown automatically recharge every time must be filled.

Perspective 2: the battery is no need to use the time to deliberate about, would like to use when filling the filling.

Survey: Most students said that the first point of view unnecessary to automatically shut down and then used as filling, but also not the second point of view, it is free of charge. Are generally used when the batteries need charging when the computer prompts further charge, of course, can be prompted to set the time, the default is to 3%.

Proposed method: The authors suggest that the majority of the students with the methods of approach are the same. In fact, regardless of the notebook to use nickel-metal hydride or lithium Dell INSPIRON 9400 Battery, these batteries have a memory effect is, the nickel-hydrogen batteries have a memory effect is obvious, but the lithium will have the same memory effect, but its memory effect than Ni-MH small number of them . On the memory effect of lithium is not only irresponsible exaggeration business advertising is completely misleading.

Since then the battery has a memory effect when charging it should be noted that as far as possible and then run out of charge, but said there is no need to deliberate to the computer must automatically shut down, so did not use up what was so bad (because the notebook has a rechargeable battery discharge protection, automatic shutdown general notebook battery has not yet reached the standard discharge protection), but you do not feel so tired? In fact, less than 3% charge on the good in this way, there will certainly be the memory effect than the natural wear and tear, it should be nothing.

As for the second charge would like to charge on the point of view, the author is completely disagree, I have already mentioned the laptop battery, whether nickel or lithium hydroxide, which have a memory effect, so if the battery life in this way would be substantially shortened
