When we buy a lapop, there is a original laptop battery and operating instruction in its package. We also can find a tip there: Calibrate your laptop battery once a month. But what is laptop battery calibration and why we calibrate our laptop battery?
Lithium-Ion Dell Latitude D630 Battery sport a battery level meter, like an electronic "fuel gauge" or State Of Charge meter which is responsible for reading the amount of charge your device’s battery holds at a certain point. Windows Mobile uses the information from those readings to display remaining battery level on your device.
Many of us may in this situation : your laptop notifies "low battery", but after a reset, power meter will show 20-30% remain, or simply the Toshiba PA3450U-1BRS battery can be not fully charged if it indicates the actual state of the battery in about 90% but not 100%. You know you have to "calibrate the battery" when it happens like this.
Without calibration the cells of the rechargeable battery can not be reconditioned, it only allows laptop "Smart" circuitry to accurately predict the level of the battery remains at all times. Battery calibration "teach" the smart battery so you can evaluate how long the fully charged Toshiba PA3399U-2BRS battery will last if - then shows the amount of remaining capacity.
A battery that is out of calibration, for example, a Toshiba PA3191U-3BRS battery show that 90% of the load, in fact less capcity remain. This can be explain taht why a laptop turns off suddenly while reporting a reasonable percentage of capacity remaining. In addition, the battery in the basic Windows screen may show 0% charge remaining after only 1.5 hours use, but the battery is only six months. Actually the battery has been fully charged and used for much more than a few months before .
If you are unsure of how to calibrate the Toshiba PA3465U-1BRS battery , this utility can run on any Tablet PC and laptop : full charge - full discharge - full charge cycle.
