I have had this happen before but usually it was shortly before the entire UPS 
died.

I had a "what the heck" moment after reading the first line. It's so 
ridiculous, you almost have to think you're misunderstanding something.  I 
guess the assumption is that the power fails more often than the battery so 
it's a net gain for uptime.

  "The UPS has an automatic self-test feature which periodically tests the 
battery. When the battery needs to be replaced, the UPS will indicate this by 
dropping the load."

  We lost all phones and networking for a few minutes in one of our buildings 
today.  The APC Smart-UPS powering the comm rack did a self-test; apparently it 
didn't like the battery and dropped the load during the test.  It re-powered 
itself after, but with "Replace Battery" lit now.  This is the second time this 
year I've had a Smart-UPS do that.  I've had it happen to me before, too.  
What's the point of a self-test if the behavior is identical to failing during 
operation?

  F'ing APC.  I bet the batteries are swollen and stuck in the unit, too.
