    How correctly for notebook computer battery charge ?

    Some provide the lithium ion battery for notebook computer, hasutilized such as the SBS wisdom battery system technology, canprecisely survey the battery life, therefore uses must be free fromworry some. Although the lithium ion battery has very many merits, butmust lengthen the battery the service life, the maintenance longertime power supply, but also needs to grasp some specialized chargemethods.

    Newly buys back lithium ion battery when primary use, must carry on 3times of complete sufficient electric discharges, namely the batteryat least must completely fill time of electricity, again puts theelectric quantity, after duplicates three time uses again. Activatesthe battery interior the chemical substance, causes the batteryinterior the electrochemistry to respond enters the optimum condition,will be allowed namely to be at will sufficient in the later usenamely uses, but will have to guarantee a month the battery must havea time of complete electric discharge, such depth will put theelectrical energy to stimulate the battery the activation performance,will be playing the key role to the battery service life. If surpasses3 months batteries not to use before, uses once more also shouldequally carry on 3 times of complete sufficient electric dischargeswith the new battery, guarantees activates the battery.

    If the use nickel hydrogen battery, must control the duration ofcharging well, should pay attention do not have frequently theovercharging, otherwise can reduce the battery the service life. Inaddition, the nickel hydrogen battery should completely dischargebefore the charge, when charge also must fully charge, also beforenormal use, also requests to complete 3 times of complete sufficientelectric discharges.

    The majority user custom when each time is using the notebookcomputer, all peg grafts delivers flows the power source power supply,very little uses the battery to supply power to the notebook computer.Actually should each month at least use the battery to supply power 12times, completely uses up the battery, again meets disposable deliversthe discharge to fill. Please remember such, said regarding therechargeable battery, uses up the electric quantity fills again,beneficial and is harmless, because the notebook computer uses thelithium ion battery existence certain inert effect, the long time doesnot use can cause the lithium ion to lose activeness, needs retoactivate. When the notebook computer uses the alternating current whenthe room is best the battery takes out, in order to avoid causes itfrequently to be at the charge condition. When charge best closes thenotebook computer, enables the battery completely to fill theelectricity, do not have to capture the power source in the chargemidway. The charge finished, should use after 30 minutes.

    Moreover, because in the battery electric quantity is very easy toexhaust, the majority notebook computer only has together the battery,therefore, the partial pens let the computer factory develop the rapidcharge rate function, let the user exhaust after the electric quantitymay use the quickest speed to supplement the electrical energy. Forexample the Dell notebook computer has the ExpressCharge function, maycharge above 90% in a hour. For is assorted is not 100%? Because actsaccording to the lithium battery the sufficient flashovercharacteristic, if frequently the rapid charge rate to 100%, thebattery life considers greatly reduces, therefore behind 10% can quicksufficiently change by before slowly imitates lengthens the batterylife.

    Had not said regarding this kind of function ordinary notebookcomputer that, the best means are the closing machine charge, theclosing machine charge can compare the opening machine charge toreduce 30% above the duration of charging.
