[Premium-Rx] RA 1792 backup battery

[John Nelson]

The Racal RA1792 CPU board uses a 2.4V NiCd backup battery. In some early
samples I have, the battery is a GE DataSentry DS2SD. This measures about 40
x 13mm and has four pins on its base, of which two diagonally opposed ones
are positive and negative. For the life of me I can't find any reference to
this device and nothing of a similar size and pinout appears to be available
in the UK. It would be easy enough to fit one of a variety of 2.4V NiMH
batteries but it would be nice to find one that physically matches the old
one. 

Any thoughts from 1792 users greatly appreciated.
