Calibrating a Battery Pack
When to Calibrate
Even if a battery pack is heavily used, calibration should be
necessary only once a month. You do not have to calibrate a new
battery pack before first use.
Calibration does not usually increase battery run time, but it can
increase the accuracy of battery charge displays, especially under
the following conditions:
■ When the battery pack has been unused for one month
or more.
■ When the notebook has been running primarily on
external power (and rarely on battery power) for more
than one month.
■ When battery charge displays report large changes in the
percentage of power remaining within 2 minutes. For
example, if the Power Meter displays 20 percent of a full
charge remaining and then less than 2 minutes later displays
only 5 percent of a full charge remaining, the rapid drop in
charge remaining indicates that the battery pack needs
calibration.
For more information about battery charge displays, refer to
“Monitoring the Charge in a Battery Pack,” earlier in this
chapter.
