[Shop-talk] Boosting a UPS?

[Mark J Bradakis]

It is hot here in Salt Lake. I got a small fan for my office to help keep me cool.
I plugged it into one of the non-backup outlets on the UPS that powers the Team.Net
server. Now when I turn the little fan off or on, the UPS beeps a few times. Interesting.

It could be a sign that I need to replace the UPS soon. Maybe time for a mini fund drive?
I have also heard that one can increase the capacity by wiring normal 12 volt car, motorcycle,
lawn tractor, etc. batteries into the circuit. Anyone have any experience doing so?

ps: About the only thing I remember from all the electrical engineering classes I took
     in college is that given enough current, any circuit element can be modeled as a fuse.
