108 CK30 Handheld Computer User’s Manual
The Main Bat field displays the voltage of the AB1G battery.
The following table shows how to interpret the voltage levels.
Main
Battery Status
Main Battery Voltage
Percentage
of Battery
High 8500 mV 100%
High > 8000 mV > 75%
Medium 7600 to 7999 mV 50% to 75%
Low 7200 to 7599 mV 25% to 50%
Critically low < 7199 mV < 25%
The Main Batt Flag field displays the battery status, which is
linked to the battery icon described on page 8. You can continue
using the battery until the CK30 indicates that the battery is
low: the battery light turns on and the low battery icon (
)
appears on the taskbar.
The Supercap field displays the voltage of the backup battery.
The main battery continually charges the backup battery unless
the main battery is critically low or removed.
Backup
Battery
Status
Backup Battery
Voltage
Condition
High > 2400 mV Fully charged
High > 2200 mV OK to swap the main battery
Low > 1750 mV OK to swap the main battery if
you first suspend the CK30
Low < 1750 mV Do not swap the main battery
because the CK30 might cold
boot
There are some usage patterns that can cause the backup battery
to become depleted. For example, if you remove the main
battery every night to charge it outside the CK30, the backup
battery will be low in the morning. This usage pattern does not
harm the backup battery.
When the backup battery is low, the Backup Battery Very Low
dialog box appears on your CK30 screen.
