Save the senile notebook battery

Along with notebook period of revolution passing, many friends obviously felt the battery gets older, the cruise duration reduced. Except purchases the new battery, has the method to be able to repairthe battery?

The overcharging and excessively will discharge creates the permanent damage to the lithium ion battery cathode, this also will be the battery life question.

But more importantly, if charging-up because the accident severs, its internal chemical reaction will be able to have the complex change, this time very possibly the cruise duration will have the influence to the battery. Therefore, the depth electric discharge and the charge are protects the notebook battery a very good solution. The very many name brands notebook, for example the IBM ThinkPad serieshas special-purpose electric discharge software, if your notebook unfortunately does not have special-purpose electric discharge software, then may carry on according to the under step. First is durable the screen protection, establishes in the Windows power source management the power source operational version for "as soon as is going directly to", but in the warning option card "the electric quantity insufficient warning" the establishment will be 10%, the operation establishes as "no operation". Afterwards "the electricquantity serious short warning" the establishment is 3%, the operationis "waits for", simultaneously adjusts the screen brightness is highest. Preserves all before works the data, and the confirmation battery charge after 80%, captures the power source and all outsidemeets the equipment.

After the electric discharge had finished the notebook canautomatically closing machine, afterwards inserts the power sourcelets the notebook charge, this process may repeatedly 2 ~ 3. In fact,this procedure goal is lets the battery continue electricity the electric discharge, but this kind of electric discharge condition is not impossible to achieve in ours daily use, its effect basic isconsistent with these special-purpose electric discharges software.

If this time or does not have the tangible effect, then basically is unable to restore the battery, may consider in the replacement lithiumion battery the core.

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)

The Laptop battery has the significant breakthrough

The notebook computer lengthens the battery period of revolution workteam (EBL-WG) to announce its low power loss display monitor planobtains the significant breakthrough.

The notebook computer lengthens the battery period of revolution workteam (EBL-WG) to announce its low power loss display monitor planobtains the significant breakthrough, the definite average may shipout more than 6 million power losses every year not to surpass 3 tilesthe low power loss 12.1/14.1/15.0 XGA display monitors, estimated willoccupy in 2004 the notebook computer to ship out the total quantityapproximately 12%.

Establishes this plan from a year ago to start, the display monitoraverage power loss already dropped from 4.3 - 4.5 tiles to 3 tiles orless ¨d¨d economical electric powers is equal extra to increases 60minutes batteries period of revolution for the notebook computer. TheEBL-WG goal will be realizes every year to the beginning of to produce1, 00.01 million power losses will not surpass 3 tiles the displaymonitors, estimated will occupy in 2005 the notebook computer to shipout the total quantity approximately 20%.

The Intel company moves the platform enterprise department migrationsupport to plan Manager concurrently EBL-WG President Kamal Shah toindicate that, the notebook computer demonstrated the subsystem holdsthe quite great proportion in the notebook computer whole averagepower loss. So far, in notebook computer interior each kind of moduleand the subsystem, involves the electric quantity which thedemonstration aspect the subsystem consumes to be most. Shah statedthat, "Along with the brand-new low power loss demonstrationtechnology appearance, demonstrated the subsystem also will certainlyto gradually decrease the power loss, thus continues to impel to movethe platform overall power loss unceasingly to drop."

He indicated that, "The consumer requests the notebook computer tohave the longer battery period of revolution the call to be more andmore high. If we must realize time charge the perfect condition whichthe entire day uses, then reduces the notebook computer to demonstratethe subsystem the power loss is the key is at."

The EBL-WG significant breakthrough indicated the manufacturer moreand more hoped reduces the platform the power loss, satisfies the userto lengthen the battery period of revolution the demand. Recentlyallied EBL-WG several companies to include: AMD, ATI Technologies Inc,BIC, Infineon, Millennium Cell Corporation, Motorola energy systementerprise department, O2Micro and Sion Power.

The great base value creation center (Acer Value Lab) vice- presidentArif Maskatia indicated that, "We universal migration life stylerequest 随时随地 can visit the information day by day. ThroughWi-Fi, the Internet visit changes more and more simple and is popular,we need to use the longer battery period of revolution to come for itto provide the powerful support, such user can truly have the splendidwireless experience."

EBL-WG unceasingly is expanding the work, in order to impels theentire profession to use its method to survey the battery period ofrevolution, from this will be allowed for the notebook computermanufacturer to appraise the different display monitor the power losswill provide an general reference. This group will be encouraging alldisplay monitors manufacturer the power loss which will surveyaccording to the EBL-WG criterion to join in its product data sheet.This plan will support the notebook computer manufacturercomprehensive appraisal display monitor characteristic to tabulate,and through will simplify the display monitor confirmation flow in theidentical place translation all correlation data.
