Oral-B Vitality Battery Replacement

Introduction

Electric toothbrushes are powered by a rechargeable battery, that enables the reciprocating brushing motion of the bristles. If your electric toothbrush loses power quickly or doesn't hold charge, most likely the rechargeable battery needs to be replaced.

This is very easy to do. I had no problems following your instructions.

Thanks.

Is this a regular rechargeable AA?

Thanks again.

The original battery is a NiCd with tabs. I just spot welded tabs onto a standard AA NiMH battery and it worked fine.

Thanks.

I did fix an Oral B Braun PRO timer (2022) and the only part that is different is the head. It has two nail presses inside, one at the switch side and the other at the opposite side, that are very difficult to lose.
