At Ionic Industries we have published another free guide to replacing the battery inside a Braun Oral-B electric toothbrush, this time for the Professional Care Type 3756 and 3754 models.
The Type 3756 and 3754 toothbrushes go by various names on the packaging, including the Professional Care, TriZone or PRO 500, 550, 600, 650, 700, 800, 1000, 2000, 3000 and 4000 etc. but all have similar internals. These are one of Braun Oral-B’s most popular ranges of electric toothbrush so we get a lot of readers using our guide.
