I presume my old Yamaha PSR uses some kind of memory back up as until now it would save songs I'd made . I posted this on another forum (general keyboard site) and got a guy arguing with me that according to the manual it only uses D type batteries for power.
Well that's obvious but I've never used it with batteries so obviously there must be something used to save settings and such!

Probably a coin-type lithium battery. They're common in computers and other hardware that save settings even after being disconnected from power. The details on such battery is probably buried somewhere in the user manual.
As for the battery being user-replaceable -- maybe, maybe not. Some are soldered in place while others are clipped. While the soldered ones can be removed, you do need to be fairly handy with a soldering iron. The actual battery itself should be widely available at any hardware store or electronics dealer. A PSR shouldn't be too hard to open up. The battery will be about the same size and shape as a US nickel.

I have some experience with electronics , (training course in the '90s) so I should be able to manage it if its soldered in. The manual doesnt mention it but then they dont want people opening their keyboards up! Will crack her open later...

I had a psr which failed to retain it`s memory without the D batteries (6 of `em) to the degree I couldn`t change the batteries witout having it plugged into the mains. I had it in bits and couldn`t find the onboard retaining device, whatever it was. The shop denied there was a problem. If you`ve had it some time, put some D batteries in if nobody else offers any other solutions . .

Batteries are too expensive and heavy, Ive never run it on batteries but it has saved stuff in the past.

The little batteries with the clips spot welded to them are typically a specific part # that electronic supply houses have. If you do identify a battery in your PSR it's advisable to order a replacement that has the same clip configuration. It is nearly impossible and dangerous to solder a clip to a battery yourself.
The owners manual does state that your keyboard 'might' have an internal battery.

Update:
I removed the back, nothing. There is a circuit board upside down but I think that's for all the switches.
But I did find a possible hack. The two wires from the battery tube. I could snip those at the tube end, solder on a square 9volt battery pad and attach such a battery!
Why oh why didn't Yamaha do something like that in the first place??

The internal battery is always on the mainboard. Sounds like you are looking at one of the little sub boards.

It's never a good thing to finally take it apart enough to then realize that to remove the battery, you would have to unscrew all the fasteners that afix the main board to the keyboards chassis. What typically happens then, as you try to remove the main board, you discover all the wiring harnesses still interfere with the extracting of the main board.
Those harnesses usually have locking plugs that can be old and brittle. And so on .....
