Correction to the Online User's Reference The following description in the information section no longer applies for your computer's battery pack. - If your battery is brand new and you are charging it for the first time, it might not become fully charged due to the characteristics of the chemicals in the cell. To maximize performance, ensure that all chemicals in the battery are fully activated by cycling the battery (fully charge, then fully discharge) three times. Also, follow this procedure if you stored the battery for a few months. - If the battery pack has not been used for a long time, it will not be fully charged with only a single charging. You will have to completely discharged it; then recharge it three to six times to maximize battery operating time.
