This guide will take you step by step through how to dismantle the Braun Oral-B Professional Care Type electric toothbrush and replace the battery. The tutorial is based on the Type toothbrush but also applies to Type toothbrushes. The type number of your toothbrush is marked on the bottom of the handle. For other toothbrush models and type numbers the battery replacement procedure is slightly different so please see our other guides to toothbrush battery replacement instead. This is documented in detail below along with lots of pictures.
Electric Toothbrush Battery Replacement (Oral B / Braun Vitality)
Can I replace the battery in my Oral-B electric toothbrush
I've been using this electric toothbrush for a few years now. Gradually the battery has lost it's ability to hold charge to the point where it needs to be plugged in or rather placed on the charging holder every few days. I though I'd try changing the battery actually 1 cell as I discovered and see if I couldn't get a performance enhancement at the same time. As with many of my Instrucables you can either read the steps here or sit back, relax and watch the video embedded here or browse my YouTube channel linked here. Set aside the main body and the spring - we won't need these until we come to reassemble the toothbrush. The PCB also has the momentary push button up near the top. Turning the mechanism over we can just see the cell yellow in colour.
