Have you checked the obvious things like the mains lead dose it have a break in it etc.

As someone who's voided many warranties in his time, I often find that a suitably sized flat jewellers screwdriver can sometimes be forced so it sits in the corners of some of the popular security heads. Sometimes you need to file the screwdriver down for a tight fit...

Be aware that the cells inside may well be solder-tag ones, soldered together to form the battery. It's nigh on impossible to solder regular batteries together like this - the solder tags are attached via a spot weld.

You can get solder tag cells from maplin etc, though probably at a premium.
