Battery Packs

Charging a New Battery Pack

Fully charge the battery pack while the tablet PC is connected to
external power through the AC adapter or an optional DC cable.
A new battery pack that has been partially charged, but not fully
charged, can run the tablet PC, but battery charge displays may be
inaccurate.

Charging an In-Use Battery Pack

To prolong battery life and increase the accuracy of battery
charge displays:
■
Allow the battery pack to discharge to less than 10 percent of
a full charge through normal use before charging it.
■
When you charge the battery pack, charge it fully. An in-use
battery pack can be charged while the tablet PC is connected
to external power through the AC adapter or an optional
Automobile Power Adapter Charger, docking station, or
DC cable.
An optional Auto/Air Cable can be used to run the tablet PC, but
cannot be used to charge a battery pack.

Monitoring the Charge in a Battery Pack

Obtaining Accurate Charge Information

To increase the accuracy of all battery charge displays:
■
Allow a battery pack to discharge to less than 10 percent of a
full charge through normal use before charging it.
■
When you charge a battery pack, charge it fully.
■
If a battery pack has not been used for one month or more,
calibrate the battery pack instead of simply charging it. For
calibration instructions, see "Calibrating a Battery Pack,"
later in this chapter.
