Ultrabay 2000 Battery

The second battery is correctly detected by either the APM or ACPI subsystem.
However, the Linux ACPI subsystem only scans for batteries on boot. This means that the second battery must be present at boot time, or you will not be able to get any info for it.
We need to find a way of telling the ACPI subsystem to rescan for batteries.
