I don't know about this specific model of Braun shaver (I have a Braun Model 7526).

I have looked at the instructions for a couple of models of Braun Shaver, and the instructions are similar so it may help you to replace the batteries in yours.

Here is one of the instructions:

2) Remove the silver sides
3) Using a small torq driver remove the 4 screws
4) Open shaver
5) Remove circuit board with batteries
6) Remove and replace circuit board with batteries (or solder in the new batteries)
