The only thing that comes to mind is to check out NUT ( Network UPS
Tools ) at http://www.networkupstools.org and see if their source code
can answer your questions.

I've been using NUT for some time with APC units and had no issues when
changing batteries, but I have a vague memory of some models being fussy
about noticing the new battery.  Google should be able to find those
discussions for you.
