Ah-hah! I'll give this a try. Unfortunately the batteries I want to use are $200 each. ;) Got a recommendation on batteries that will last with constantly being charged by the UPS?

You can't use just 1 battery. The APC units want to see 24vdc, so you need two batteries running in series.

It works perfectly, as I have 20+ remote locations running off two gel type batteries. Make sure you install some type of a fuse on the positive side of the connection.

I believe I remember some discussion on this list on connecting an external battery to an APC UPS. I'm in the middle of doing it right now and am having problems. The UPS just beep continuously with the 'bad battery' light on. I'm using a Lifeline deep cycle battery. Any ideas?
