Activation of a new battery
1 views: we buy a new battery laptop battery in, there will be more than 3 percent of electricity, the battery's remaining power is used up, then shut down until the 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.
Recommendation: According to the author information available to indicate that the activation of the battery work should be completed at the factory, and laptop battery factory belt a little electricity, natural wear and tear in order to avoid damaging the battery. Cell activation, it should be in the absence of protection circuit conditions.
Circuit itself can be a lithium battery protection circuit, this circuit is designed in order to avoid over-charging and discharging batteries dell laptop battery . Fully charged battery, the charging indicator goes out, the battery on the charge is not into power. At this point you to plug in the power plug to charge the battery is also of little use. The situation from the battery, the battery can see there is no charge.
There is a simple way to determine whether the battery during charging:
Heat when the battery charge when the battery is full after an hour (do not pull the power plug), you try the battery again to see if the battery does not heat heat. 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 dell Y9943 battery does not charge a full picture of skills, simply so that they charge 10 hours, so this should be the business of expediency.

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.
Proposal: 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 dell RC107 battery 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 individuals, not very comprehensive.
At present, many notebook manufacturers are taking into account the vulnerability of the battery, and the product added to the battery protection technology, and thus the corresponding different brand laptop battery charging protection technology is different, like some large companies dell Latitude D620 battery have done very well in this , such as: the original IBM, Hewlett-Packard, Compaq, Toshiba. Which is considered the most thoughtful HP.
HP's notebook computers can detect the battery discharge situation, only less than 95% of the battery will automatically recharge when. 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 dell 312-0386 battery .
However, some "small brand" notebook batteries, may not enjoy such treatment because it did not take the protection of the battery technologies, such as a certain brand of notebook computer battery is full on top, in the use of external power supply when the first positive 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 is equivalent to charging the battery once, although only a small charge will be the time. It is proposed that we use the machine in accordance with  the case may be, look at the notebook description, choose whether to use an external power supply the battery dell PC764 battery removed.
