subject: Notebook in the use of a longer period of time [print this page] Notebook in the use of a longer period of time, prone to the problem of declining battery capacity, resulting in shortened battery life notebook. This is mainly batteries inside the battery due to aging or failure. Serious cases, the use of battery calibration procedures or repeated charge and discharge the battery can not solve the problem. For this problem, dell laptop battery there are many fans that the battery case open, find and replace failed batteries will solve the problem. Reality is it really?
Replacement batteries should be cautious
Since many laptops now use lithium ion batteries, and lithium-ion battery life is basically constant, and its rechargeable life span of only 500 to 800 times. HP laptop battery So if on battery power frequently, 1 to 2 years, the battery is easy to achieve because of the internal life of the batteries fail. While we open the batteries when the battery test, is shown in one or two batteries damaged. However, due to other batteries that is about it, even if you replace the failed batteries, battery back to normal in a short time, will soon fail for other batteries can not be used again, leaving the entire battery.
So,Acer as07b31 Battery the laptop battery to replace all the internal ability to solve all the problems? In fact, this is difficult. Because the original battery, its internal batteries is the result of precise matching, and therefore the capacity of batteries, terminal voltage and internal resistance of a good consistency. And we bought in the market, batteries, and has not been tested and matched, we can not for the amateur conditions, matching batteries, Acer as07b41 Battery so its capacity, internal resistance and other parameters will inevitably vary. In the internal battery, the batteries are charged together in series (in most laptop batteries, is divided into two groups of 8 batteries, 4 series and then parallel to form a battery pack), due to the battery charging current as of which the smallest capacity batteries will certainly be full of electricity, while the battery is not sufficient because the other, so the terminal voltage of the battery pack can not set the voltage, the charging circuit will continue to charge the battery pack. In this way, the original will be fully charged batteries overcharge.
