Does anyone here have DX9 D12 Gabriel? I need some help replacing the batteries.

I can see both forearms are exactly the same. Is it just a matter of twisting off the battery compartment (ie claw part on right/rocket nose part on left) on both forearms? There seems to be a little bit of ?give? on these parts.

So if the elbows are oriented downwards, should the battery compartment be turned clockwise or anti-clockwise? There is no mention of replacing the batteries in the instructions. Concerned something will break.
