Thanks Bill!
I guess a super-cap would have done the job but, given the small available space inside the Ax (about ~15mm dia x ~3mm deep) , it wouldn't have a much capacity. Panasonic super-caps of that sort of size are 0.1F - 0.22F.

The Varta cell I used is 1.5mAh which is, very-very approximately, ~3F. I suppose it's possible that the prototype Axims used super-caps and the spec's were not updated.

The cell Dell used is the same physical size as the Varta, but has no obvious markings other than '5D f+' on the tab (which may be obscuring markings on the cell itself).
