Calibrating a Battery Pack

Three steps are involved in calibrating the battery pack: fully charging, fully discharging, and then fully recharging.

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.

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 you notice a significant change in battery run time.

■When battery charge displays seem inaccurate.

For more information about battery charge displays, refer to the “Monitoring the Battery Pack Charge” section earlier in this chapter.
