Which battery is flat

Did you press a button to change the display ?

Does the engine turn over, that voltage I would think would be too low making it the leisure battery most likely

Looks like no-one can tell from the display or the button positions. But by measuring a couple of voltages it would be easy to tell. There's a number of threads on how to do this, it's probably easier than you might be thinking if you've never used a multimeter before. Have a read of this one for example.
