Has anyone opened a Gigapan Epic Pro battery, the one with a 5.5mmx2.5mm connector on one side and there must be six NiMh cells enclosed.
I bought an Epic Pro second hand with two batteries, one completely dead and the other almost.
On ebay I found electrical compatible cells (the size maybe wrong), and if I only knew how the housing of the battery pack could be opened without destroying too much I would like to give it a try to exchange the set of cells and close the pack again.

Don’t worry about the electric intricacies, for that I think I am well qualified.
But I would like to pass the real test: the opening of the pack in such a way that it can be reused.

Any clarification is welcome and if possible a picture tells a thousand words.
