3V lithium battery for internal memory backup in the Roland MKS 50, Alpha Juno rack synthesizer.
This Panasonic 3V lithium battery is used to retain internal memory data in the Roland MKS 50, the rack version of the Alpha Juno synthesizer.
It allows patches, MIDI settings, and system parameters to remain stored when the unit is powered off.
The battery matches the original type installed in the MKS 50 and is suitable for maintenance and restoration of vintage Roland rack synthesizers.
Battery replacement requires soldering and should be carried out by a qualified technician.
