Re: Float charging PP3 (as a ups)

What I'm after is basically a simple UPS. Will something along the
lines of the following work?
http://www.nogsnet.com/personal/images/ups.jpg

The connectors on the left are connected the PSU, the connectors on
the right connected to my load (the fire alarm circuit) and the
battery in the middle is my PP3.

If this does work what chemistry battery should I use and what would
be the float voltage?

Sorry if I have something wrong, I am a computer programmer not an
electrician (only by hobby). Feel free to correct/hurl abuse at me.

Looks ok... Just ensure that the current charging the battery is about 10mA
max
