RELM UC 2200 VHF Transceiver

[btritch]

I'm not sure where this is supposed to be posted but I have a question, I have a Relm Communications Inc. Model Number UC2200, Serial Number: 7120006265, It's A VHF Radio Programmed at the time for 2 Channels, Channel 1 is Currently MURS 4, 154.570, Channel 2 is blank. I looked online and I couldn't find any information on it anywhere on google, I searched by both serial and model number and also by name and model number. I will need a new battery, It says BP700 7.2 Volts 700MAH, Rechargeable NICD. It's a square battery on the bottom of the radio. I didn't find anything on RELM Communications website either, So does anyone know anything about This brand/type of radio, mainly where the batteries can be purchased and what program will reprogram it, I'd like to program it to my fire channel with my dept. here if it's compatible with thieir system, Which is should be if I had the software to program it. Does anyone have idea where to find information on this type, Batteries, Program Software, etc.?

Note: I can post a picture if anyone needs one!
