battery.runtime is in seconds, so that agrees with the UPS display as
well.

APC batteries have a smart chip that records stuff like that and can
be read by the UPS.  Another possibility, is that they "refilled"
an old case.  The end result was a substandard (but working - and
cheap) battery.

That fluctuating runtime sounds suspicious - although the load is also
fluctuating between 32 and 28 in your examples.  Maybe the lower
runtime is a consequence of the higher load?  Why is your load varying?
It might be something plugged into the UPS.  Maybe your server makes
the load difference when CPUs are maxed out?
