As I recall it is one that has an internal battery to hold model memory? If so it has never been replaced and that would cost more then the radio is worth? It .
GB Hitec transmitters have all used non-volatile memories including your Prism 7X, They have never needed memory batterys.
AllModes the Hitec (s) plug on your Hitec servos are compatible with all the modern current plugs including the JR, Airtronics (Z) and Futaba (J).
