I re-read the original report, and it seems like I misread: this was
*not* an issue on OpenBSD, and should therefore need no further
testing here.

Since Joseph has helped confirm that things are now working also on
FreeBSD, and no one else has commented in 3.5 weeks, I'll go ahead and
close this bug.

If anyone is still seeing issues with M-x battery on any *BSD system,
please reopen the bug report.

Best regards,

Running M-x battery in FreeBSD returns:

Power disconnected, battery high (illegal% load, remaining time 0:00)

The battery-bsd-apm function was contributed in [1]. It contains:

(apm-cmd (concat "/usr/sbin/apm -ablm" apm-flag))

The -m flag used in NetBSD[2] and OpenBSD[3] to show the remaining time
in minutes does not exist in FreeBSD[4]. Instead -t should be used to
show the remaining time in seconds.

Also the resulting output is in a different order than that expected by
the parser. battery-bsd-apm expects the order to be:

battery-status
battery-percentage
battery-life
line-status
apm-mode

In FreeBSD it is:

line-status
battery-status
battery-percentage
apm-mode
battery-life

As can be seen in the source of /usr/sbin/apm.c[5]
