COMMERCIAL NOTEBOOK BATTERIES: PERFORMANCE OPTIMIZATION (cont.) BATTERY CALIBRATION DEFINED With the advancement in technology, the battery industry continues to provide solutions aimed at improving methods of accurately measuring a battery's charge capacity. Inherent in today's battery chemistry, the ability to store energy diminishes with each charge cycle. The Fuel Gauge that measures charge capacity is not able to account for the gradual diminishment in capacity. As a result, over time the gauge's measurement becomes inaccurate. To maintain the measurement accuracy, Compaq recommends periodic calibration about every 90 days to reassess the energy storing capacity of the cells. To complete the calibration of a battery, a full charge of the battery must be followed by a full uninterrupted discharge. Unless these two steps are completed together, proper calibration is not achieved and continued accuracy of the battery's Fuel Gauge cannot be assumed. The more frequently the battery is subjected to partial charges and discharges, the more frequently the battery should be calibrated. IMPORTANT! Although the Battery Calibration tab displays all batteries installed in the system including those in the ArmadaStation, only those batteries installed in the computer battery bay or MultiBay can be calibrated The battery can be calibrated using one of the following methods: Compaq Power Management Suite (PowerCon32) Unattended Battery Calibration Utility Manual Calibration 3
