longer than nickel-based batteries of comparable size. Also, Li-Ion batteries can be charged before they are fully discharged because they are not susceptible to the memory effect. A typical 6-cell Li-Ion battery pack takes 2.5 to 3 hours to fully charge to its maximum voltage with the system in off - Compaq nx9008 | Lithium-ion battery technology: Getting the most from Smart Batt - Page 3
or about one year of use (Figure 2). This estimate covers typical users who completely cycle the battery each working day by running low to medium power applications (word processing, e-mail, and spreadsheets) in wired or wireless modes. Figure 2. Full charge capacity with moderate use is about - Compaq nx9008 | Lithium-ion battery technology: Getting the most from Smart Batt - Page 4
charges will continue to decrease. Table 1 summarizes FCC projections after one year based on 2 user profiles and various power loads. The first profile is for a mobile user who fully discharges and charges the battery almost every working day (300 cycles per year) in a normal environment.

in monitoring and managing Li-Ion batteries, HP Compaq notebooks provide accurate and instantaneous status information using Smart Battery Technology. HP Smart Battery Technology is based on the Smart Battery System (SBS), which was established by major battery manufacturers in 1995 to promote an - Compaq nx9008 | Lithium-ion battery technology: Getting the most from Smart Batt - Page 6
will be plugged into AC power continuously (via a wall adapter or docking station) for more than 2 weeks. • Use the type of battery with the highest capacity (Ah) rating if the notebook will run high-end applications on battery power. • Periodically calibrate the battery based on the usage model - Compaq nx9008 | Lithium-ion battery technology: Getting the most from Smart Batt - Page 7
