Few acpi BIOSes does not support _BST (battery status) method, causing
that type of weird sysctl output (since it depends solely on _BST).
Your hope is to use acpiconf(8) i.e acpiconf -i <battery number>.
Unfortunately, acpiconf itself does not display all possible
values.

Try this patch against usr.sbin/acpi/acpiconf/acpiconf.c

  http://people.freebsd.org/~ariff/acpi/acpiconf.c.diff

Hopefully you will have the proper output in terms of percentage.
You won't have advance battery status such as remaining time and few
others. This is a limitation for BIOSes without _BST.

I believe Nate Lawson is the right person to comment on this.
