No battery that I can see, here's a couple of pics of the expansion:

/edit - I just noticed the flying lead has come unsoldered, I wonder if that's the problem there.  Can anyone confirm, it's the small pin with the track leading to the connector that needs to be resoldered?  I can do that tomorrow.

Looks like it goes next to the one still soldered. Its the only thing around with solder on the pad.
