 All three units were taken for a one hour 40 minute walk over outback
 terrain.  During the walk, psu_0/capacity_percentage was logged along with
 wireless signal and noise level.  The other battery monitoring parameters
 were not logged.  Each unit experienced the same usage pattern as part of
 a structured coverage test, beginning with fully charged battery,
 according to the monitoring parameters.

 On unit Quozl 3, the battery capacity remained at 100% throughout, and
 when it was returned to AC adaptor power showed a green battery light, and
 the battery status showed "full".

 On unit Quozl 2, the battery capacity declined as expected, and when
 returned to AC adaptor power showed a red-orange battery light, and the
 battery status showed "charging".

 On unit Quozl 1, the battery capacity declined as expected, and when
 returned to AC adaptor power showed a light-orange battery light, and the
 battery status showed "charging".

 All three units are on build 193 with A62 firmware.
