Belkin Battery Backup Unit

This is a good find. I've been reading about uses for the Belkin Battery Backup Unit BU3DC001-12V Rev B UPS. These units were used for AT$T's Uverse box to keep the phone powered for emergencies. It outputs 12V into a very standard coaxial connector. The internal battery is a 12V 7Ah SLA battery. I picked my unit up on eBay for about $25 used including the battery.

Now that I have one of them, I'd like to get a couple more.

Here's a like to one of the blogs I was reading about this unit:
