The Main Batt Flag field displays the battery status, which is
linked to the battery icon described on page 7. You can continue
using the battery until the CK31 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.

There are some usage patterns that can deplete the backup
battery. For example, if you remove the main battery every night
to charge it outside the CK31, 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 CK31 screen.
