Is it a BackUPS Pro, by any chance?  They sort of straddled the two  
model lines and had some features I normally associate with SmartUPS  
units.  I have some older BackUPS 300, 600, and 900 units, and they  
don't do load tests.

Package tape also does a pretty good job of making "packs" out of  
multiple batteries.  You can fold over the end and leave it hanging  
as a handle to help get the pack out for replacement, next time.
