Minolta Hi-Matic F Camera Battery Adapter

This adapter allows 2x LR44 (or SR44) coin cells to be installed in a Minolta Hi-Matic F camera, or similar. The camera originally took two RM-640 battery cells, which are no longer available.

To finish the adapter, a small metal strip must be installed in the slots in order to join one side to the other. I recommend 0.1mm thick bronze.

NOTE: The different voltage between the original 1.35v cells and the 1.5V+ alkaline/silver oxide cells does not affect the operation of the Minolta Hi-Matic F. The shutter speeds are independent of voltage in this camera.
