Status: offline 		Can anyone tell me if the backup battery in a JR PCM10X is draining all the time or does it only drain when the main battery is removed/flat?

Also can the data be retained during backup replacement by the main battery?

Thanks,

Malcolm

Yes it is quite normal for all memories to be safe

As in post #2, provided a JR Tx is turned on for a few moments every second day, the capacitor saves drain on the battery.
This will provide 3<5 years life for the on board Lithium button cell but even 7 years has been realised by frequent users.
If replacing the button cell is not done correctly, then user will loose their model data, the following may assist:

Good photos and schematics to use a cell holder rather than hard solder to board
