Braun Oral-B Professional Care Type 3728

We often get feedback from customers and today we received a tip that the single-speed version of the Braun Oral-B Professional Care type 3728 electric toothbrush takes a 42mm long by 17mm diameter battery (1.2V NiMH). These are available to buy in our replacement toothbrush battery shop now. The three-speed version of the 3728 takes a different size – the 42mm by 14mm diameter battery. Double-check your brush by opening it up before buying from our shop.
