Activation of new battery
It is not necessary to charge the battery for 10 hours to activate the battery activity and activate it according to the normal charge and discharge mode.
Suggested method: According to the information provided, the activation of the battery should be completed in the factory. The battery is shipped with a small amount of power to avoid damage to the battery caused by natural loss. The activation of the battery should be carried out without a protection circuit. The lithium battery circuit itself has a protection circuit. The purpose of this circuit is to avoid excessive charging and discharging of the battery. Generally, when the battery is fully charged, the charging indicator is off. The battery is not charged, then what is the use of plugging the power plug on the battery? It can be seen from the condition of the battery that the battery is not charged. In addition, you can tell you whether the battery is charging or not when you charge the battery. When the battery is fully charged, it will be heated for one hour. Plug is not pulled), you try the battery again, see if the battery is still hot? The result is definitely cold, because the battery is not in a state of charge and discharge, of course, it does not heat up. Notebook manufacturers will recommend charging new batteries for more than 10 hours at the factory . The author's view on this is that notebook manufacturers should consider that some new users can not fully grasp the charging skills when using new batteries, and simply let them charge for ten hours, so this should be the expedient of the business.
How to charge properly
Most people say that it is not necessary to use automatic shutdown to recharge, and do not charge very casually. Generally, when the battery is used to remind the user that it needs to be recharged, the charging time can be set by itself. The default is to 3 %.
The method suggested by the author is the same as that of most people. In fact, regardless of whether the notebook uses lithium or nickel-metal hydride batteries, these batteries have a memory effect. The memory efficiency of nickel-metal hydride batteries is obvious, but lithium batteries also have a memory effect, but its memory effect is smaller than that of nickel-metal hydride. . The statement that lithium battery has no memory effect, but the irresponsible exaggeration of advertising behavior by the merchants is completely wrong guidance. Then since the battery has a memory effect, it should be noted when charging, try to use up and recharge, but do not have to deliberately say that the computer must be automatically shut down, so there is no harm in using it (because the laptop battery has charging and discharging) Protection, the general notebook automatic shutdown does not reach the standard of battery discharge protection), but do you feel so tired? In fact, this method is better than 3 % charging, and the memory effect will definitely be there. It should be nothing compared to natural loss. As for the idea of ​​filling the charge, the author is totally disapproved. I have already said that the notebook battery, whether it is nickel-metal hydride or lithium battery, has a memory effect. If it is used in this way, the battery life will be greatly shortened.
Whether to unplug the battery when external power is supplied
Most people use the external power supply to remove the battery. Only a few of them use the external power supply when the battery is on the top, and the brands used are several international brands.
In fact, whether the battery is removed or not, the contradiction mainly focuses on whether the battery is charged when using an external power supply. It should be known that the number of times of charge and discharge of the battery is directly related to the life. Generally, the number of charge and discharge times set by the lithium battery is fixed, the number of times of charging is only 400 - 600 times, and the number of products that have been specially improved is not more than 800 times. Going forward to retirement. The first point is nothing more than the fear that when the power is used, the battery will be charged on the top, which not only increases the number of times of charging, but also causes overcharging. The second view is that a fully charged battery is placed on the computer and will not be recharged when using an external power source.
In fact, both views have their correct side, but there are also some mistakes. Because this is just a view expressed by individuals, it is not very comprehensive. After the author's investigation, many notebook manufacturers now consider the vulnerability of the battery, and added protection technology to the battery in the product, so the corresponding brands of laptop batteries Charging protection technology is different, like some big manufacturers do very well in this regard, such as: IBM , HP, Toshiba, Compaq and so on. The most thoughtful of these is IBM , IBM 's laptop can detect battery discharge, and ThinkPad will only automatically charge when the battery is less than 95 %. This can play a very good role in protecting the battery, and now many other manufacturers have followed suit. So a battery like this, you don't need to pull it out when you use it, because it only charges when the battery is below 95 %. Even so, if you are using the computer for a long time, it is better to remove the battery, because the heat generated by the notebook for a long time will cause some damage to the battery. However, some other "small brand" laptop batteries can not enjoy this treatment, because there is no protection technology inside the battery. Like a laptop brand used by the author, if the fully charged battery is placed on the top, you must first charge the battery when using the external power supply, because the battery will be lost when stored, it is impossible to reach 100 %, as long as it is not 100 % When the power is connected, it will be charged. Each time an external power supply is connected, it is equivalent to charging the battery once , although it only takes a small amount of time. Therefore, it is recommended that you use the machine according to the situation of your own machine, check the notebook manual, choose whether to remove the battery when using external power supply.
