Has anyone found a UK source for the internal CR1220 PCB battery with the correct pin configuration?
They're also used in the CME BodyGuard.
We're paying nearly £12 each for the "official" ones, but the only ones I can seem to find by a third-party (eg: RS @ £1.08) requires a little tweaking and risks shorting the pins!

Any help to save a little would be much appreciated.
