My Liebert UPSs (two PowerSure Interactive 1000's) have never done that, 
but I have had several APC's that have.  I have noticed, however, that 
my Lieberts shut themselves down and refuse to power on when their 
batteries are at the end of their useful life, but the APC's keep going 
and light up the bad battery indicator.  I haven't decided which 
behavior I like less.
