Background
The Oral-B Sonic Complete Type 4717 Toothbrush is an electric toothbrush from Oral-B powered by Braun. It uses a 56mm x 17mm NiMH battery.
Identification
Oral-B uses “Type numbers” to identify their large catalog of electric toothbrushes. Type numbers are usually a more effective way to locate repair and service information for your specific toothbrush.
Note that the packaging or box might also list a Type number, like “Type 3757.” This is the Type number for the charger, not the toothbrush. To learn more about Oral-B Type numbers, visit their support site. The type number (4717) can be found on the bottom of the brush. It has Braun Oral-B and Sonic Complete branding on the face of the brush.
