APC Smart UPS shows overload with no load attached

How do I deal with a Smart UPS 1000 that shows overload after self
test when no load is attached? The inverter sounds quite a bit louder
than usual.
This unit worked fine for a long time until it was unplugged for
precisely 2 weeks and moved...
Typical failures of APC UPS -- in order of frequency
(based upon an APC refurbishment operation):
1. Battery
2. Charger circuit for battery
3. Inverter circuit from battery to outlets
