Thanks for the help.  I'm not sure I can change much about this UPS. 
When I run "upsrw" for it here is all I get back:

Interval to wait after shutdown with delay command (seconds)
Value: 64

There is nothing apparently settable about its LB point via the driver. 
  BTW -- What do you think "ups.delay.shutdown" means?

I hate to say it, but I guess I'll just have to pull the plug and see 
what happens....
