Question about laptop battery
Question:
My notebook uses the alternating current in the belt battery situation, the duty fence demonstrates is charging. Asked by now the notebook consumed the electricity was comes from the battery or the alternating current? When the battery fills 100%, by now the duty fence demonstrated uses the alternating current. Asked by now the notebook used was the battery electricity or the alternating current electricity?
Answer:
When your notebook belt battery uses on the other hand, this time ison the one hand charges by the city electricity power supply, the notebook consumes the electricity completely to come from to the alternating current. When the battery fills 100%, so long as the duty fence demonstrates uses the alternating current, then this time writes down originally can stop charging, also completely uses the alternating current to supply power. Needs to remind you is, if the long time does not use the battery, suggested takes down the battery, this regarding lengthens the life to be of great advantage. Surely do not have frequently to carry on the charge to the battery, because the lithium ion battery also has the life limit.

Knowledge about li-ion batteries
1. Lithium ion battery high performance
Does not contain any mercury, the cadmium virulent element, is thetrue environmental protection battery.
Besides has flowed the hot dual protection, but also in sets at theintelligent IC protection circuit.
Has the power carrying capacity, fully satisfies the camera/numericalcode camera each correlation load power request, displays theoutstanding constant pressure source characteristic.
But fast completes the charging-up, completely does not have thememory effect.
Even if the high efficiency sufficiently puts, high frequency use, itscycle life still compared to nickel hydrogen battery more than 1 timesabove.
The electrically charged maintenance ability is strong, the monthelectrically charged maintenance rate is bigger than 92%.
Has the finest internal uniformity, guaranteed each time "sufficientlyputs" the process uniformity, guarantees the battery longest overalllife
2. Lithium ion battery principle of work
The lithium ion battery principle of work refers to its sufficientelectric discharge principle. When carries on the charge to thebattery, on the battery positive electrode has the lithium ionproduction, the production lithium ion after the electrolyte movementto the cathode. But assumes the laminated structure as the cathodecarbon, it has very many pores, arrives the cathode the lithium ion toinsert to in the carbon level pore, inserts lithium ion more, thecharging capacity is higher. When carries on the electric discharge tothe battery, inlays the lithium ion leaves in the cathode carbonlevel, also the movement returns to the positive electrode. Returns tothe positive electrode the lithium ion many, the discharge capacity ishigher. Usually said the battery capacity refers is the dischargecapacity. The lithium ion battery sufficient electric dischargeprocess is from the positive electrode -> cathode -> positiveelectrode rate process.
3. Lithium ion battery security feature
Regarding the lithium ion battery security performance inspectiontarget, on international had stipulated below the extremely strictstandard, a qualified lithium ion battery should satisfy the conditionin the security performance:
<1> Short-circuits: Does not catch fire, does not explode
<2> Hot box experiment: Does not catch fire, does not explode (150 ℃constant temperatures 10min)
<3> The needle perverses: Does not explode (penetrates battery with Ф the3mm nail)
<4> Plate impact: Does not cook meals, does not explode (the 10kg heavyitem to pound from the 1M high place to battery)
<5> Burns down: Does not explode (coal gas flame to bake battery)
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.
