What is the Smart Battery Calibration?

Von laptop, 05:42
Repeated short-discharge and loading operations lead to discrepancies between the charge state of the battery and the battery gauge. The battery must be regularly calibrated to its usable capacity “to learn new,” so that it can synchronize its state of charge with the DELL XPS M1530 battery gauge. The calibration of the life of your notebook is optimized by the user receives an accurate estimate of remaining battery charge. Calibration also prevents data loss can occur if, during the resting state is not enough energy is available to perform critical storage operations on the hard disk.
Smart Batteries calibrate their FCC each time they go through a full Entladungs-/Ladezyklus, regardless of whether they are charged in a notebook or in a special charger. To calibrate the Dell Inspiron 1525 battery in the notebook is complicated because the process can take up to 4 hours. The result of this method can be more meaningful than using a special charger.
The results of calibration with the notebook are relevant because the battery’s FCC gets new, while it is exposed to a realistic power load. In a charger of the DELL Latitude D630 battery with a predetermined load is discharged. If this burden is lower than the load, the notebook is normally exposed, the learned capacity of the battery are greater than actual capacity. In other words, the new calibrated battery may not provide the running time, which is forecast by the battery indicator when it is exposed to a greater load than that with which it was calibrated.
The accuracy of today’s Smart Battery enables precise calibration when the Dell GD761 battery is discharged to about 5% of its remaining capacity. Consequently, the user can set the battery alarm at 5% of the remaining capacity for the smart battery’s capacity can be calibrated during normal use.
The user simply has to periodically discharge the Dell Inspiron 1520 battery until the capacity alarm is triggered at 5%. It depends on the individual conditions, whether this procedure is necessary. In general, a lithium-ion battery at least every three months to be calibrated. A battery that is seldom discharged completely should be calibrated about once a month.
