Hi @youssefsalib,

Please confirm the model number of your toothbrush?

In this question you said it was a Braun 3756 and in the question above it's a 3746.

They don't open the same way so showing the correct model number is important

If it is a Braun 3746 model, here's a guide that shows how to replace the battery in a Braun 4729 and a 3746 model toothbrush.
