#12517: OFW text-formatted battery status may indicate "charging cooling"
(contradictory) at the same time

A XO4 with Q7B14/EC 0.3.10 on it was watched while charging a NiMH battery
from near-flat status. The battery got hot (~42C) so cooling was likely;
but OFW said that the battery was doing both "charging cooling" at the
same time.
In reality, the voltage & current readings indicated charging, and there
was no slow flash I recall of the charging LED.
This was true with both the "watch-battery" or "test /battery" commands,
which I believe provide the same output.
If an OFW battery status is seen again with "charging cooling" in it, the
following command should be run and the result noted to see if this is an
EC problem or an OFW one:
ok 70 ec-cmd-w@ .
