To give these nice people here and their information about the DX80 something back, I just registered here and have images of the disassembly destruction of the battery part.

The DX80 stopped charging and after contacting the support, they send me a new one. TOP!

Later I tried to find out, why the first one stopped charging, to avoid mishandling the new one.

You all know how the battery back looks like, therefore I have no picture of an intact one here :)

First I removed the "do not disassembly" plastic cap, which was the easy part.

After that I tried to use force everywhere, but nothing more came out, besides the battery pack itself moved around a bit, just did not came out.

After some more brute force I got it open, here are the pictures and some notes, which may be help someone else not to destroy it too much in case of service needs :)

Besides my dremel cut, this what it looks like to remove the plastic cap:

I guess, if use some tools to turn flat surfaces, the black aluminum ring should be able to be removed by simple unscrewing it. Since I had no luck , I cut the ring and was able to lift it out with a little force.

That's it. The battery pack then came out.

This is how the electronics looks like. I got some corrosion and blown diodes and stuff there :(

These are the batteries. Maybe I can reuse them for something else :)

So have found with your DX80 and see you :)

Best,
