Maybe, maybe not.  It depends on what protocol your UPS uses.  A cursory 
glance over the compat list didn't list it, but you should certainly 
look for yourself, especially if it goes by more than one name.  Also 
google around, some quick googling for Energizer ups nut found a few 
drivers for NUT which may or may not work for you.  You'll have to read 
the fine print.  :)

Check out NUT (Network UPS Tools) at http://us1.networkupstools.org/  It 
may very well support your UPS, and having used both it an apcupsd, I 
can say that NUT is both better, and a touch more work to configure. 
But it supports *dramatically* more hardware, and there is good 
code-sharing going on between apcupsd and NUT's APC driver.
