Updates on my progress for info only, I have managed to find (after much searching) a supplier of the correct batteries and a holder to replace the identical matching battery in my SDR from an electrical spares company called conrad-electronic.co.uk,
This should cut down of the effort to replace the old bios battery with a bigger version and keep it all neat and tidy on the board, I will update with photos once I have made progress, the parts should be with me in the next few days.
