•To ensure you always have battery power available, purchase a spare standard or extended battery. The spare battery can be charged in the Battery Charger. For more information on purchasing optional batteries, visit the HP Web site at www.hp.com/go/ipaqaccessories.

Checking Your Battery

To check your battery charge level:

•From the TodayPanel on the Today screen, tap the Battery icon > Main tab.

•Or from the Today screen, tap Start > Settings > System tab > Power > Main tab.

You can view the amount of battery power remaining for both the main battery and the backup battery.

The main battery provides the HP iPAQ with power when it is not physically connected to the cradle or AC adapter. The internal backup battery provides the HP iPAQ with enough power to maintain data when you remove the battery for short periods of time. When the backup battery is fully charged, it maintains data for up to 15 minutes. However, you should always replace the main battery (extended or standard) immediately to minimize the drain on the backup battery.

If the main or backup battery charge level is low, recharge the battery by connecting the HP iPAQ to AC power using the cradle or the AC adapter

or insert a fully charged battery into the HP iPAQ. When the HP iPAQ turns off (due to low battery level) and does not turn on again, you have only

up to 72 hours to recharge the battery before you lose data.
