Agreed batteries are unreliable, an alternative to battery based UPS
are flywheel energy storage devices, they come either as an integrated
solution with the diesel generator (i think cat offers such a package)
or as a standalone UPS (see:
www.pentadyne.com/uploads/18/File/Pentadyne-VSS-Brochure.pdf)
another vendor is Active Power (which i think partners with cat)
They seem to be MUCH more reliable than batteries from what i read
HE probably acquired one of those solutions
