As I understand it, the corrosion affected the 'cable' linking the batteries and module to the main PCB and the seller has got round this.
This is the comment from the seller "The electrolyte "wicks" up the flexible PCB and corrodes the internal PCB's distroying the unit. On some, only the first flexible PCB is affected. I remove this, clean up any residue and fit a usb power lead You can then power it from your PC or monitor. Alternatively I can supply a "wall-wart" for mans operation or an external battery box that takes 4xAA cells".
I intend to go for the latter.
I suspect the cable is soldered but not sure to which part. Why is it worse being soldered to the battery foil?

PS links should work, but you may need some patience. I used some free web server to host the pics and their webserver may not like it if you look at both pictures at the same time or perhaps other people are trying to download the same image ?
