I want to replace the rechargable battery in a Braun / Oral-B electric toothbrush. There are several videos on youtube showing how to disassemble one, such as
which appears to show a very similar model, but it doesn't work for me.
I've removed the ring at the top, and the base, and released the little plastic clips, but the mechanism doesn't slide out as shown in the videos. I've applied a lot of pressure, so I think there must be some concealed screw or similar.
Has anyone solved this problem?
