As the battery is soldered directly to one of the pcb's in the front of the radio the rearmost one making it relatively easy to remove the pcb I decided to replace it with a CR coin cell battery and to mount a battery holder onto the pcb. It's a good idea to change these atregular intervals anyway as i've known them to leak electrolyte onto the pcb which in turn attacks the copper track. To check it was retaining it's last used frequency I programmed a simplex frequency into the radio and then switched it off and left it off for anhour then checked, the last used frequency was still there.
