 Battery Monitor is a battery monitor for laptops. It displays the current
 status of the battery (charge/discharge and energy level) as well as some
 information about the general health of the cell.
 .
 Due to the way Battery Monitor is implemented it currently works only on
 Linux 2.6 kernels with ACPI and that too reliably only on some acpi/bios
 combination (it is being worked on: the /proc file system is very
 inconsistent.) A user-contributed patch to make it work on FreeBSD has been
 merged in.
