Has anyone ever tried to use a 3.6v ni-cad battery from a cordless phone as a PRAM battery ? I made my own 4.5v battery for my PPC 5500 out of a 9volt battery(1/2 of the cells) and it works great. My 3.6v phone battery looks about the same and has wires already ! Will it work as a PRAM battery in my G3 ? ?Any thoughts ?
