Hello Nutters,<br>
<br>
I'm running nut 2.7.2 on FreeBSD 10-stable (via the FreeBSD port)
with an APC Back-UPS CS 350 connected via USB. I get persistent
(every few minutes) messages logged "battery is low" but I don't
understand why. I don't think it's for the reason described in the
FAQ (but I'm not 100% sure).<br>
<br>
In the trace output I can see that UPS.PowerSummary.RunTimeToEmpty
is usually around 150 - 170 seconds. Occasionally it drops to 105. I
don't see any reason why the load would be changing significantly.
In any case, I've set the threshold to 90 seconds in ups.conf.<br>
<br>
See below for debug info.<br>
<br>
If somebody could offer suggestions on how to fix it, I'd be very
grateful.<br>
<br>
Thanks in advance,<br>
   Graham<br>
